Page | 1 Invisible Forces and Powerful Beliefs: Gravity, Gods, and Minds By the Chicago Social Brain Network FT Press Upper Saddle River, NJ Page | 2 Invisible Forces and Unseen Powers: Gravity, Gods, and Minds Preface 1. Invisible Forces Operating on Human Bodies Gravity is an invisible force that holds us to the surface of the earth, and the fact that gravity is invisible does not place it beyond scientific scrutiny. Similarly, humans are a quintessentially social species whose need for social connection produces invisible forces on our brain, behavior, and biology that are subject to scientific investigation. Among these are forces that compel us to seek trusting and meaningful connections with others and to seek meaning and connection with something bigger than ourselves. The story of these invisible forces speaks to who we are as a species. From Selfish Genes to Social Brains 2. The Social Nature of Humankind The human brain has evolved under the guidance of selfish genes to produce more than a brain that is capable of powerful, isolated information processing operations. The human brain also evolved with inherent capacities for social cognition, compassion, empathy, bonding, coordination, cooperation, values, mortality and a need for social connection that extends beyond kin and even other individuals. From Inclusive Fitness to Spiritual Striving
 
 3. Science, Religion, and a Revised Religious Humanism The dialogue between science and religion, if properly pursued, can usher in a new era of religious humanism in the leading world religions. Their central beliefs and practices largely would remain intact, but their views of nature and their concerns with health and wellbeing would be refined through their conversations with the sciences. How this model would work is discussed in terms of the relation between love and health in Christian theology – especially the tension between the agape, caritas, and eros models of Christian love. 
 The Status of the Body Politic and the Status of the Body Itself 
 4. Health by Connection: From Social Brains to Resilient Bodies Most people feel socially connected most of the time. Felt connectedness is typically taken for granted, but the effects of its absence, as experienced in feelings of isolation, demonstrate that our evolutionary heritage as a social species has potent implications for health and well-being. 
 From Relationships to People and Groups to Relationships with God
 
 5. Psychosomatic Relations: From Superstition to Mortality It has long been recognized that mental states can impact health and well being, but the causal pathways have only recently begun to be understood. Thoughts, beliefs and attitudes can have powerful effects on physiological functions, health and disease. Examples range from superstitious beliefs associated with voodoo, bone pointing, or other black rituals to the more positive states associated with spirituality. The present essay considers these disparate psychological states and how they might translate into physiological effects having real health implications. 
 The Mind and Body Are One
 
 6. The Suspension of Individual Consciousness and the Dissolution of Self and Other Boundaries A special case of social interaction concerns two or more individuals engaging in temporally coordinated Page | 3 actions that imply particular timing patterns such as synchrony or rhythmic turn taking such as applauding in unison or the ‘wave’ that is produced by thousands of individual sports fans in a stadium. A model to explain such synchronized behavior is proposed in terms of the neural processes that are jointly recruited. One of the main implications suggested by this model is that taking part in or being part of a synchronized social interaction gives rise to a qualitative shift in subjective experience due to the difficulty of applying an individual centered explanation to collectively produced spontaneous co-action. You and I as One 7. Action at a Distance: The Invisible Force of Language Language forms the fabric of our social institutions and makes tangible the nature of our relationships. Although the function of language is typically viewed in terms of the information content that it provides, some of the social function of language may depend on the way it affects us. The idea of language impact – how language directly affects our emotions and social connections – may be fundamental to the way the social brain functions to connect people. 
 Systems and Signals for Social Coordination

 8. Hidden Forces in Understanding Others: Mirror Neurons and Neurobiological Underpinnings Specific brain regions in the monkey contain individual brain cells, or neurons, that respond to both observation and execution of identical hand and mouth actions. Brain imaging in humans has demonstrated that our brains have similarly localized regions with similar properties. These areas respond to execution of goal-directed actions of the hand and mouth and during observation of the same or similar actions. Interestingly, these brain regions in the human are also responsive to observation and imitation of facial movements, and appear to be sensitive to their emotional content. 
 Connecting and Binding Social Brains and Minds 
 9. Empathy and Interpersonal Sensitivity Empathy is thought to play a key role in motivating prosocial behavior, guiding our preferences and behavioral responses, and providing the affective and motivational base for moral development. While folk conceptions of empathy view it as the capacity to share, understand and respond with care to the affective states of others, neuroscience research demonstrates that these components can be dissociated. Empathy is not a unique characteristic of human consciousness, but it is an important adaptive behavior that evolved with the mammalian brain. However, humans are special in the sense that high-level cognitive abilities (language, theory of mind, executive functions) are layered on top of phylogenetically older social and emotional capacities. These higher level cognitive and social capacities expand the range of behaviors that can be driven by empathy. 
 Seeing into My Mind and Other Minds 
 10. Seeing Invisible Minds Other minds are inherently invisible. Being able to "see" them requires learning about other minds, attending to other minds, and projecting one's own mind onto others, and seeing minds in other agents can mean the difference between treating others as humans versus as objects. 
 Inferring Minds When None Can be Seen 
 11. Anthropomorphism: Human Connection to a Universal Society Page | 4 The human motivation for social connection extends beyond the boundary of the human in the (often misunderstood) religious language of anthropomorphism. In this chapter, an infamous sermon from colonial America—“Sinners in the Hands of an Angry God”—is used to illustrate the way anthropomorphic language works to incorporate human society in a web of ethical obligations that connect to the natural environment and, by imaginative extension, to the universe as a whole. 
 Personifications of God 
 12. How Does God Become Real Becoming a person of faith is not so much about acquiring certain beliefs but about learning to use one’s mind in particular ways; the often intensely private experience of God is built through a profoundly social learning process. 
 Belief and Connection 
 13. Theological Perspectives on God as an Invisible Force The beliefs that religious individuals hold about the way God operates in human life are potential factors affecting perceived social isolation. My paper discusses a specific type of such belief that is common in the history of Christian thought: the belief that God is an invisible force of a rather impersonal sort working for the good in everything that happens. The paper argues that this sort of belief has as great or greater potential than belief in God as a personal friend to give one the sense that one is never alone, but the conception of God as pervasive can also lead to inattention and disconnection. 
 The Elusiveness of Meaningful Connection 
 14. Visible Efforts to Change Invisible Connections Despite the human need for social connection, many individuals are lonely because they are unable to create meaningful social bonds. Interventions designed to reduce loneliness have not been successful, suggesting that a better understanding of loneliness, social connection, and the obstacles to forming meaningful connections with others is needed. 
 Reflections on Invisible Connections 
 15. Social Brain, Spiritual Medicine? Science and religion are inextricably intertwined in the practice of medicine. Science has provided modern medicine with extraordinary diagnostic and therapeutic capacities that can be employed to care for patients. Religions provide a fuller vision for the worthiness of caring for the sick, a framework to guide the application of medical science in that endeavor, and practices that strengthen the human capacity for treating patients as the mindful persons they are. Invisible Forces
 16. Epilogue Invisible forces that connect individuals to society, or to each other, have effects at both ends of the connection. As humans we are fundamentally individual and fundamentally social. We encompass both the pursuit of rational self interest of Homo economicus and the pursuit of approval, belonging, and intimacy of Homo socialis, the former grounded in eros, the latter in agape. These forces acting together represent a signature feature of Homo sapiens (the wise ones) and have contributed a record of influence and impact– both positive and negative –that is unmatched in biology. Page | 5 Preface We view our past through a reverse telescope, making it seem like contemporary events are a much larger part of our history than they are. Hominids have been estimated to have evolved about 7 million years ago, with our species having evolved only within approximately the last 1% of that period. The human brain was sculpted by evolutionary forces over tens of thousands of years, whereas the human achievements we take for granted, such as civilizations, law, and art, have emerged only during the past few thousands of years. A mere 300 years ago, theology and philosophy were the principal disciplinary lenses through which the world was viewed, and from which explanations and instruction were sought. Advances in science over the past 300 years have transformed how we think, act, and live. Nearly every aspect of human existence, ranging from agriculture, commerce, and transportation to technology, communication, and medicine, has been transformed by contemporary science. We have no hesitation to accept scientific explanations of physical entities being influenced by invisible forces such as gravity, magnetism, and genes. But when human mentation and behavior are the objects to be explained, deterministic scientific accounts seem to many to be less satisfying. For some, science and modernity are akin to the apple in the Garden of Eden, responsible for our fall from Grace. For others, theology and religion represent little more than the stuff of superstition with no place in an educated society. About six years ago, we had the opportunity to create a most unusual group of scholars to examine questions about the invisible forces acting on, within, and between human bodies. Superb scholars who individually had made major contributions to their own disciplinary field – fields as divergent as neuroscience and medicine to philosophy and theology – were invited to form an interdisciplinary network of scholars to consider such questions. The development of these discussions even over the first few meetings truly astonished us all. We decided to share what we learned through the present book, which represents a different perspective, one in which our understanding of human nature is enriched by serious insights and scrutiny that each perspective has to offer. Theology and religion have always relied on unseen forces as the basis for explanations of human behavior and experience. Science has been able to explicate those forces even if along different lines than originally conceived. As we start to consider some of the more complex aspects of human nature, science and theology may be able to work together to shed light on some of these complexities. We begin this preface and each chapter with a word cloud produced using Wordle at http://www.wordle.net. In the case of this preface, it illustrates key concepts that are found in this book. In the case of the chapters, the word cloud in each provides a visualization of Page | 6 the key terms and ideas expressed in that chapter. Each chapter, in turn, represents a contribution led by a particular member to the network but broadened to reflect the interactions of the network on that topic. Perusal of the word clouds across chapters makes the flow of ideas more visible. Together, the chapters speak to who we are as a species and the nature of the invisible forces that make us such a unique species. For instance, humans seem to strive for social connections in a variety of ways from friendships to identification with groups to religious affiliations. A major thesis of this book is that we are fundamentally a social species, and that this journey is less a march toward isolation and autonomy than it is a march to competence, interdependence, coordination, cooperation, and social resilience. Guiding us through this journey are our social brains, which have evolved to create anything but a blank slate at birth. We owe a debt of thanks to many for their contributions and support over the years, but we owe special thanks to Barnaby Marsh for approaching us with the idea of forming such a network and for his many contributions to the network, and to the John Templeton Foundation for their support and for their encouragement to pursue questions, ideas, and conclusions of our science regardless of where they led. Page | 7 Chapter 1 1 Invisible Forces Operating on Human Bodies We may believe we know why we think, feel, and act as we do, but various forces influence us in ways that are largely invisible to our senses. Gravity is an invisible force that holds us to the surface of the earth, and magnetism is an invisible force that we use in everyday life. The fact that gravity and magnetism are invisible to us does not place them beyond scientific scrutiny. Similarly, there are a host of forces that, over the course of human evolution, have emerged to influence our thoughts, emotions, and behaviors. Because many of these forces are 1 The Chicago Social Brain Network is a group of more than a dozen scholars from the neurosciences, behavioral sciences, social sciences, and humanities who share an interest in who we are as a species and the role of biological and social factors in the shaping of individuals, institutions, and societies across human history. The scientists and scholars in the Network differ in background, epistemologies, beliefs, and methods. After five years of working together, we found a common set of themes to have emerged in our work despite the differences among us. These themes, which provide a different perspective on how we might think about human history, experience, and spirituality, are examined here and explored in more detail in subsequent chapters. elemental, we will be dealing with an area of human behavior that has also been addressed for centuries by various religions. Among these are forces that compel us to seek trusting and meaningful connections with others and to seek meaning and connection with something larger than ourselves. The story of these invisible forces speaks to who we are and what our potential might be as a species. In short, it is the story of the human mind. The mind can be thought of as the structure and processes responsible for cognition, emotion, and behavior. It is now widely recognized that many structures and processes of the mind operate outside of awareness, with only the end products reaching awareness, and then only sometimes. But clearly we know a great deal about the mind from what we experience through our senses. It is just commonsense that we know the shape or color of an object from simply seeing it. Or do we? It is obvious that the tops of the tables depicted in the top panel of Figure 1 differ in size and shape. You may be surprised to learn that your mind is fooling you, that the tops of the table are precisely the same size and shape. If you don’t believe it, trace and cut a piece of paper the size of one table top and then place it over the other. Selfevident truths can sometimes be absolutely false. Page | 8 The science of the mind is not unique in this regard. As the historian Daniel Boorstin (1983, 1) noted: Nothing could be more obvious than that the earth is stable and unmoving, and that we are the center of the universe. Modern Western science takes its beginning from the denial of this commonsense axiom . . . Common sense, the foundation of everyday life, could no longer serve for the governance of the world. When “scientific” knowledge, the sophisticated product of complicated instruments and subtle calculations, provided unimpeachable truths, things were no longer as they seemed.” (p. 294) And just as the observation that we roam on stable ground led to the incorrect inference that we are the center of the universe, so too is the modern notion that the human brain is a solitary, autonomous instrument whose connections with other brains is a matter of deliberate choice and of no real import. The human brain, the organ of the mind, is housed deep within the cranial vault, where it is protected and isolated from others, so it may seem obvious that the brain is a solitary information processing device that has no special means of connecting with other brains. But we are fundamentally a social species. Faces, expressive displays, and human speech receive preferential processing in neonate as well as adult brains. When a person feels rejected by others, their brain shows the same pattern of activation as when they are exposed to a physically painful stimulus. Permit a person to cooperate with others, and their brain shows the same pattern of activation as when they are given a rich reward such as delicious food or drink. We may not be aware of it, but human evolution has sculpted a human need for social connection, along with neural circuits and hormonal processes that enable and promote communication and connection across brains. As we shall see in the chapters to follow, our sociality is an important part of who we are as a species and it plays an important though often invisible role in the operations of our brain and our biology. Among the questions we examine is whether our social brain also contributes to the ubiquitous human quest for spirituality. The Chicago Social Brain Network For hundreds of years, theology and philosophy were the hub disciplines of scholarship, and other fields of inquiry orbited around this dyad and were tightly constrained by it. Over the past three centuries, the sciences have come into their own, displacing theology and philosophy at the center of the academic universe. In so doing, they have produced extraordinary advances in everyday life. People may reminisce about the good old days, but thanks to science and technology the amount of total income spent on the necessities of food, clothing, and shelter dropped from 80% in 1901 to 50% in 2002/2003. Yet there remains an inchoate sense that something is missing in our lives, something intangible and elusive. Science has improved our material lives, but improvements in material life may not be enough to optimize human well being. Can these two very different ways of seeing the world be used Page | 9 synergistically to shed new light on the human mind? In the Fall of 2004, we established an ongoing network of more than a dozen scholars unbounded by disciplinary precincts, geographical borders, or methodological perspectives to set aside antagonisms that had grown up between science and humanities in order to explore this question. These Network scholars hail from disciplines as disparate as psychology, neurology, theology, statistics, philosophy, internal medicine, anthropology, and sociology. Each of these scholars was well known in their own field and were busy with other obligations, but it was the opportunity to achieve a deeper, more comprehensive discussion of the human mind that made it worth the time and effort it required to be part of the Network. Although various members of the Network interact on a daily or weekly basis, the entire Network convenes twice annually for a four-day retreat to discuss each other’s research, to critique each other and to learn from one other. Scientific analyses characterized by rigorous experimental designs and data analytic strategies are interlaced with rich philosophical, theological, and historical analyses of the same questions about invisible forces that act on us all. The dialogue between the Network scientists and the scholars from the humanities and theology is bidirectional. For instance, the beliefs and behavior described in the humanities and theology are rich in hypotheses that can now be tested empirically, and the measures and methods of the behavioral sciences and neurosciences now permit rigorous investigation of some of these hypotheses. Each of the Network members brings a unique perspective to the study of the human mind, and the provocative story of the mind that is emerging from the collective efforts of the Network is the subject of this book. The Network is unconventional in other ways, as well. Traditionally, scientists and scholars work together to achieve a common understanding and a consensus position. We quickly learned that we did not need to come to a consensus to benefit tremendously from the dialogue on the capacity and motivation for the ubiquitous human quest for sociality and spirituality. For instance, there is no consensus within the Network on whether there is a God, and we do not seek here to provide the final word on what science and the humanities each have to say to the other about the human mind. Instead, our purpose is to illustrate the possibility and importance of engaging others whose views we may not share in a serious dialogue on such topics. Among the lessons we as a Network have learned are: 1. that some questions about human nature and our social and spiritual aspirations have been asked by humankind for thousands of years. Accordingly, there may be more to be gained from engaging in a collaborative process of thinking about these questions than from demanding simple and immediate answers. We discuss what we see as possible answers to questions about our nature and strivings, but the value in stating these positions is to have clear positions from which to move thinking and research forward. Thus, our purpose in writing this book is to articulate ideas to be shaped and refined, not to provide the final word. Page | 10 2. that one need not agree with a position to perform a deep and thorough analysis of the arguments for and against the position. Objectivity in thought and analysis are keys to reaching a deep understanding of a topic. By taking a position, developing arguments for and against the position, then taking the opposite position and doing likewise, we develop the capacity to be more dispassionate and powerful thinkers – and gain deeper insight into a topic. 3. that one need not reach agreement with someone to learn a great deal from discussions with them or to make significant advances in addressing a complex question. The salve of affirmation can lead us to seek like-minded others and to denigrate and avoid those who disagree with us. Although this may provide temporary comfort, it does little to help address deep divisions or solve problems with which we must deal in an increasingly complex and diverse world. There are inherent tensions between the sciences and the humanities, and these tensions have led to a polarization of views, an “it’s my way or the highway” approach toward those holding divergent points of view. The contents of this book illustrate an alternative possibility. The Network is a very interdisciplinary group, and the perspectives captured in the subsequent chapters reflect some of the same tensions with which other books dealing with science and religion have dealt – and from which they have not benefitted. The tensions reflect deep and enduring differences in the way in which scholars in the humanities, the social sciences, and the sciences think about theory, methods, and evidence. These differences can test one’s mettle but if acknowledged, respected, embraced, and pursued, they result in a richer, more innovative and synergistic collaborative effort. In the case of our Network, this was neither easy nor quick, but it was achieved through a mutual respect and exchange of ideas and a shared conviction regarding the importance of the Network’s combination of approaches from the humanities and the sciences. In a sense, our Network is a microcosm of the structure that exists in our society. If these tensions are embraced and used to their full catapultic effect, one can make progress on serious problems, transforming not only how we think about the problem, but also how we think about those who hold different or opposing views. 4. that the insights or advances we can achieve need not be our or our opponent’s position, or a less-than optimal compromise between the two, but rather they can be truly innovative, building on and transcending both initial positions. The specific forms of such creative and transcendent solutions are difficult to articulate in advance but there is a thought process – characterized by clarity, openness, constructive criticism, and synthesis – that Page | 11 Background increases the likelihood one will reach such solutions. All of the perspectives discussed in this book have been transformed through this process. In pursuing the tandem lines of inquiry of science and the humanities, the Network itself serves as an example of the human capacities and emergent processes that can derive from collective social structures and actions. In the chapters to follow, the Network examines the nature and power of unseen forces ranging from human coregulation to physiological effects of spiritual beliefs. The exchanges across disciplinary perspectives suggest that the “dominion of the solitary individual” is insufficient to understand the human mind or to optimize human health and well being. To understand human nature and the human mind, one may need to appreciate human needs and capabilities that have not been given due attention. Homo sapiens are a social species, which means there are emergent organizations beyond individuals that contribute to the ability of our species to survive, reproduce, and care for our offspring sufficiently long that they too survive to reproduce. As a consequence, evolutionary forces have sculpted neural, hormonal, and genetic mechanisms that support these social structures. Among the possible consequences explored in this book are that: 1) people are not the entirely self-interested, short-term thinking, rational decision makers assumed by the mythical creature, Homo economicus, and 2) some of the amorphous dissatisfaction and chronic diseases that characterize contemporary society may be, in part, the consequence of the denial of the differences between the nature of these two beings. Existing scientific studies of religion have established the pervasiveness of religious beliefs and practices and an association between these beliefs or practices and physical as well as mental health. Religious beliefs and practices have also contributed to failures to heed life-saving medical advice and to the horrendous treatment of others. It will be through the serious investigation of such beliefs and practices, not through their denial, that we may ultimately be able to identify which aspects of these beliefs and practices are beneficial, for what individuals and in what contexts, and through what specific mechanisms. Recent research has made it patently clear that William James (1890, p. 442, 2) underestimated the faculties of human infants when he suggested that their first sensory experiences were a “blooming, buzzing confusion.” But what James’ sentiment did capture is the overwhelming complexity and uncertainty that exists in the child’s environment, and the inherent difficulty in making sense of that complexity from scratch. Our drive to make meaning is irrepressible---and when we do not understand the forces that drive our actions, we invent narratives that make these invisible forces feel more predictable and understandable even if only in hindsight. But we do not do it alone. Adults as well as children must explain the uncertainty and ambiguity of natural phenomena (calamities of weather, death and reproduction) as well as social phenomena (human agents) in order to operate effectively. But not all actions are perceived as being equivalent. Forces operating on objects to compel action, as when gravity causes rocks to slide down a mountain, are Page | 12 viewed as external causes. Forces operating on human bodies to produce action, in contrast, are viewed as reflective of purpose, driven not only by external causes but, more importantly, by abstract reasons such as goals, aspirations, and destiny. The meaningmaking proclivities of humans are so irrepressible that when external forces operate on human bodies to produce a significant impact on humankind, even the causes of the actions of these human bodies tend to be regarded in terms of more abstract purposes and reasons. The anthropomorphic description of hurricanes is a case in point. Actions of objects have causes, whereas actions of humans have reasons. Invisible forces that operate on humans but that appear to operate independent of human agency have been the subject of religious speculations for centuries. These invisible forces include: internal neural and biological forces (e.g., homeostatic processes, autonomic activity) that exert regulatory forces which are largely hidden from conscious experience or control; strong emotions that seem to arise apart from conscious human intention (e.g., rage, fear, empathy); phenomena such as dreams or hallucinations that seemingly operate independent from the human will; motivations, biases, inclinations, predilections (such as anthropomorphism, ambiguity avoidance, preference for simple explanations, etc.) whose presence is so universal that, like language, the capacities for their development or expression may have an evolutionary basis; individual beliefs (such as the belief that there is a reality outside our head/we are not dreaming; the belief in human freedom; in values such as equality, etc), attitudes, preferences, goals, or intentions; aggregated beliefs that result in social norms, values, religion, culture, and social movements; and codified forces such as decrees, rules, alliances, and laws. Before the enlightenment of the 18th century, many scholars believed that thought was instantaneous and that action was governed by an indivisible mind separate from the body. If a palpable cause for a person’s behavior could not be identified, the Divine or some counterpart constituted a more agreeable explanatory construct than invisible forces acting through scientifically specifiable mechanisms. Unparalleled advances in the sciences have occurred since the dawn of the Enlightenment, including the development of scientific theories about magnetism, gravity, quantum mechanics, and dark matter that depict invisible forces operating with measurable effects on physical bodies. During this same period, serious scientific research on invisible forces acting within, on and across human bodies was slowed and underfunded in part because the study of the human mind and behavior was regarded by many in the public and in politics as soft and of dubious validity. The result is that many still regard the mind and behavior as best understood in terms of the actions of non-scientific agents, such as a god or gods, and the manifestations of mental illness as the result of a failure of individual will – a denial of the possibility that invisible forces (that is, forces that are tractable scientifically but of which a person is not normally aware) can affect mind and behavior. One could try to explain away the gap in scientific knowledge about invisible forces by referring to the conception of science and religion as Page | 13 systems of knowledge that are in opposition. This approach is common and evident in a spate of contemporary books that take the position that science and religion represent competing ways of understanding the world and that science (or religion) is the one and only valid way of understanding human behavior and the world around us (3-8). For instance, in The God Delusion, Richard Dawkins places specific Judeo- Christian theological doctrines under the scrutiny of science only to find that none passes scientific muster. The vast majority of people from all educational backgrounds continue to harbor strong religious beliefs that affect their daily decisions and behavior, with both good and ill effects. These religious belief systems most commonly bump into scientific claims around invisible forces. When science opens up opportunities to improve the human condition by providing a more complete understanding of the causes of events, their measurable effects, and possible interventions– ranging from valid science education to medical advancements based on stem cell research – these opportunities are often threatened by the application of specific religious beliefs to these endeavors. Scientific research to understand religion and religious belief systems may be a more productive response than broad denouncements by scientists of any who hold such beliefs. Conversely, when religion opens up opportunities for improving the human condition by questioning the emphasis on short-term self-interests at the expense of the collective, providing a more complete understanding of the human need to attribute meaning to events and their effects, and identifying possible interventions– ranging from the provision of tangible support to individuals in need, to the promotion of healthy lifestyles and ethical behavior– scientific research to understand these influences may again be a more productive response than broad denouncements by scientists that such beliefs are irrational. Indeed, the question of whether God exists is of much less scientific interest, and of much more questionable scientific merit (how would one scientifically falsify such a claim?), than the question of the causes, consequences, and underlying mechanisms for the observable human behaviors affected by invisible forces--- whether they be physical (gravity), social (groups), or perceived spiritual (gods). Contemporary science explains many of these phenomena but also points to the human capacities and emergent processes that derive from collective social structures and actions and, underlying the emergence of these structures, the human need for meaningmaking and connecting to something beyond oneself. The dominant metaphor for the scientific study of the human mind during the latter half of the 20 th century has been the computer – a solitary device with massive information processing capacities. Computers today are massively interconnected devices with capacities that extend far beyond the resident hardware and software of a solitary computer. The extended capacities made possible by the internet can be said to be emergent because they represent a whole that is greater than the simple sum of the actions that are possible by the sum of the individual (disconnected) computers that constitute the internet. The telereceptors (e.g., eyes, ears) of the human brain have provided wireless broadband Page | 14 interconnectivity to humans for millennia. Just as computers have capacities and processes that are transduced through but extend far beyond the hardware of a single computer, the human brain has evolved to promote social and cultural capacities and processes that are transduced through but that extend far beyond a solitary brain. To understand the full capacity of humans, one needs to appreciate not only the memory and computational power of the brain but its capacity for representing, understanding, and connecting with other individuals. That is, one needs to recognize that we have evolved a powerful, meaning making social brain. Social species, by definition, create structures beyond the individual– structures ranging from dyads and families to institutions and cultures. These emergent structures have evolved hand in hand with neural and hormonal mechanisms to support them because the consequent social behaviors (e.g., cooperation, empathy, altruism, etc.) helped these organisms survive, reproduce, and care for offspring sufficiently long that they too reproduced. From an evolutionary perspective then, the social context is fundamental in the evolution and development of the human brain. The observable consequences of these higher organizations have long been apparent, but we are only now beginning to understand their genetic, neural, and biochemical basis and consequences. To fully delve into these complex behaviors, science needs to deal with the invisible forces that shape human life, whether it is in the form of physical, biological, or psychological forces. For instance, anthropomorphism, the irrepressible proclivity to attribute human characteristics onto nonhuman objects to achieve meaning, predictability, and human connection, is beginning to be subjected to productive multi-level scientific analysis. Experimental studies have shown that manipulations which increase feelings of social isolation without the possibility of resolving these feelings through human interaction have the compensatory effect of increasing people’s tendency to anthropomorphize, including heightened beliefs in God. This scientific work has implications for understanding claims regarding the success of religious practices such as solitude as paths to feeling closer God. Research on anthropomorphism has now identified developmental, situational, dispositional, and cultural factors that modulate people’s tendency to anthropomorphize nonhuman agents ranging from technological gadgets to animals to gods, and the neural mechanisms underlying this transconfiguration of nonhuman objects into human-like agents are beginning to be revealed. Guided by the insights from these new scientific theories of anthropomorphism, historical analyses may be worthwhile to determine whether concepts of god have changed across time and cultures such that god was created in the image of the believer rather than vice versa. Xenophanes (6th century B.C., cited in 9), for instance, was apparently the first to use the term “anthropomorphism” when describing the similarities between religious agents and their believers, noting that Greek gods were invariably fair skinned and blue-eyed whereas African gods were invariably dark skinned and dark-eyed (joking that cows would surely worship gods that looked strikingly cow-like). Brain imaging research has confirmed Page | 15 that anthropomorphism is associated with the activation of the same prefrontal areas that are active when people think about themselves or project themselves onto others. Conclusion Just as critically, the study of invisible forces requires a discussion of the method that successful teams use to work together as they cross disciplinary boundaries. Over the past few decades, there has been a demonstrable shift from the individual genius as the source of scientific and scholarly breakthroughs to interdisciplinary teams. This shift in the production of cutting-edge knowledge has been documented in all fields of scholarly activity, ranging from mathematics and theoretical physics to the humanities. This shift has both made possible and been necessitated by a need to understand complex behaviors. Although this project is primarily about the ways that scientists seek to study the impact of invisible forces, it will also reflect the methodologies that these researchers use so that their work is not constrained by common knowledge. The philosophy of science also looks different when dealing with simple causality (one-to-one relations) than with complex causality. Affirmation of the consequent, a logical error in which a given cause for an effect is inferred based on the observation of the effect, does not lead to a scientific error when there is but a single cause for the observed effect. However, as scientific inquiry addresses increasingly complex phenomena, and increasingly complexly determined phenomena, the philosophy of science needs to become more nuanced. A core challenge is to develop a “science” of identification and aggregation of these invisible forces at different levels. Related research questions include why they exist, and measures of robustness. One of our central goals is to demonstrate not only that considerations of these forces matter, but that that they can matter a lot. There also are questions of value and ethics that could be implicated: descriptive knowledge, models, awareness of causal relationships, and so on, might not be enough to answer some kinds of questions, especially those related to value and purpose, which are the very energies that animate and invigorate real human systems. Economics comes close with its proxy measure of value based on the distribution of scarce resources and people’s varying need for these resources. But this theory comes up short in many instances where other values are at play that are beyond markets, such as in assessing the value of a human life, or whether all lives are of equal value. It is an especially poor model for helping us understand something as simple as the value of articles of sentimental value, such as family photographs, which may have little or no market value at all. Thus, how do we best understand the “sentiments” that are important in the real world? The members of the Network have worked beyond the boundaries of disciplinary borders, geographical precincts, and epistemological comfort zones to develop a rigorous but innovative approach to the study of the human mind, sociality, spirituality, health, and well being.

Page | 17 From Selfish Genes to Social Brains The Chicago Social Brain Network was established to examine how science might inform us about our fundamental human nature, including the apparently irrepressible quest for connection with a higher understanding and organization. Science can describe what religion does in rigorous ways that benefit religion, and religion can serve a meaning-making function that science itself disclaims. This is not to say that science can address the existence of God. Our Network instead focuses on the consequences of believing in such a mind and of seeing into that mind. In the next chapter, John Cacioppo, a social neuroscientist, draws on work on evolutionary theory, sociobiology, and evolutionary psychology to examine the implications of the selfish gene hypothesis for Homo sapiens. He shows how the notion of the selfish gene has been joined with political theory, consumerism, and economics to produce a dominant modern image of humans summarized by the phrase “what is best for me is best for the society.” Without rejecting the selfish gene view, Cacioppo shows how it evolves in humans into what he calls the “social brain”– a large cerebral cortex and an interconnected limbic lobule that together are sensitive to the complexities of physical and social environments. Central to this complexity is the long period of dependency of the human infant and the interdependencies of adult humans for survival especially in hostile environments (e.g., warfare). For the selfish gene to contribute its DNA to the ongoing gene pool, the individual must not only reproduce but also cooperate with others to assure that his or her offspring also grow to maturity and reproduce. This leads to natural selection choosing those genes and capacities that contribute to cooperation, reciprocity, attachments, and generosity. Over the millennia of human evolution, this process has created the social brain and made humans a unique social animal. Page | 18 Chapter 2 2 2 The lead author is John T. Cacioppo, Ph.D., the Tiffany and Margaret Blake Distinguished Service Professor in the Departments of Psychology and Psychiatry and the Director of the Center for Cognitive and Social Neuroscience at the University of Chicago. He is a co-founder (with Gary Berntson) of the field of social neuroscience, a past president of the Association for Psychological Science and a recipient of numerous awards including the National Academy of Sciences Troland Research Award and the American Psychological Association Distinguished Scientific Contribution Award. Cacioppo’s research concerns the neural, hormonal, genetic, and behavioral mechanisms underlying the operation and maintenance of the emergent structures that characterize social species generally and humans in particular. He has published more than 400 scientific articles and 16 books, including Loneliness: Human nature and the need for social connection (2008, Norton Books) and Handbook of neuroscience for the behavioral sciences (2009, John Wiley & Sons). Cacioppo is also the Director of the Chicago Social Brain Network. Cacioppo has been interested both in the similarities and the differences between humans and other species. Human social cognition, emotion, behavior, and executive functioning – that is, our social brain – are especially sophisticated compared to those found in other species. Research in the neurosciences sometimes focuses so much on mechanisms divorced from the social settings and functions they may have evolved to serve in social species such as our own that the generalizations to humans are inaccurate. Animal models permit experimental control and interventions that cannot be carried out in humans, but understanding the implications of this work for the human brain and biology depends on explicit The Social Nature of Humankind Social species, by definition, are characterized by the formation of structures (e.g., dyads, families, tribes, cultures) that extend beyond an individual. Although we may revere the rugged individualist, we are fundamentally a social species. I begin by discussing some of the invisible evolutionary forces that led members of our species to band together to form such structures. I then consider how selfish genes (e.g., through anthropomorphism, 1) might have led to social brains and why the social connections and structures created by humans are especially powerful and flexible. Finally, I describe a nonintuitive way of thinking about the absence of satisfactory social connections (i.e., loneliness), mention how and why chronic loneliness can be so harmful, and discuss how our need for social connection motivates us to search for meaning and connections beyond ourselves and other individuals. One implication that is explored here, and in more detail in the essays to follow, is that genetic and cultural adaptations, not human ignorance, may be fueling the search for meaning and connection with a transcendent entity or being. Mythic Individualism For at least the past century, we have celebrated the power and intellectual might of the solitary genius. This includes individuals such as Thomas Edison who brought electrical power to individual households, transforming night into day; Henry Ford who introduced the mass production of comparison to and knowledge of the rich benefits of human social interaction and feelings of connection. This essay addresses this gap in our thinking about the genetic, neural, and hormonal processes that constitute our brain and body and in doing so provides a different perspective on who we are as a unique biological species. Page | 19 automobiles, changing how we transported and consequently how and where we worked and lived; Charles Darwin who argued that the difference in mind between humans and other species, great as it is, is one of degree and not of kind; and Albert Einstein who surmised a relationship between energy and matter, opening a universe of possibilities that previously was virtually unimaginable. As a result, the cultural focus moved from a focus on the social group – the family, neighborhood, or society – toward the autonomous individual. Forty years ago, the dominant metaphor for the human mind was the digital computer, complete with inputs, filing and memory systems, limited processing resources, and outputs. Evolutionary theory focused on the selfish gene and, by extension, on the individual whose purpose for living was to survive long enough to reproduce. Milton Friedman influenced economic theory and government policies for decades by positing that people, being fundamentally rational, are motivated first and foremost by self interests, and the adage of “united we stand, divided we fall” was supplanted by the notion that what is best for the me is best for the society. Moving from an economy based on manufacturing for the masses to one based on catering to idiosyncratic consumer interests further fueled a focus on the preferences of the autonomous individual. One can certainly find evidence in humans and other species for the view of life being best understood in terms of self-interest. Sardines, for example, swim in what appears to be synchronized schools until approached by a predator, at which time they dart about so chaotically that they create what appears to be a large, tumultuous ball with a mind of its own. The rule governing the behavior of this dynamic and adaptive collective action can be explained entirely in terms of self-interests. Each fish is driven to swim to the middle, where it is less likely to be eaten by the hungry predator. Sardines are born with the capacity to swim, find food, and avoid predators. If they survive long enough to reproduce, their genes will be part of the gene pool for future generations. That is, if those who are genetically predisposed to swim to the middle are more likely to survive predation, then the genetic predisposition to swim to the middle will become a characteristic of a larger percentage of sardines in future generations. The sardine ball is an example of a more general phenomenon, in which the choices made by members of a group endow the collective with properties that are consistent, predictable, and purposive enough that we can speak of them as “behaviors” of the group, even though the collective actions of the group are not directed by any of the individual members. This phenomenon can be called “emergent,” because the properties or behavior of the group are not determined by any individual but arises from the collective behaviors of the individuals who constitute the group. Social structures like the sardine ball have evolved because the sardines whose genes compelled them to swim to the middle in the presence of predators were more likely to survive to reproduce, thereby contributing these genes to this species’ gene pool. According to the National Science Foundation’s Tree of Life project, there are anywhere between 5 million and 100 million species on Page | 20 Earth, only 2 million of which have been identified thus far. Most of the species identified are either born with the capacity to find sustenance and avoid predation sufficiently well that some survive long enough to reproduce, or they are born in such large numbers that some survive long enough to reproduce. It is the ability of such organisms to reproduce that determines what genes constitute the gene pool for the future generations of that species. These genes, in turn, shape the structure and function of the organisms that constitute a species. This reasoning led George Williams (2) to suggest a half century ago that traits (i.e., behavioral tendencies) which benefit the group at the expense of the individual would evolve only if the process of groupselection was great enough to overcome selection within groups. He further suggested that group selection is nearly always weak, so that group-related adaptations do not exist (3). Richard Dawkins (1) popularized the notion that traits which evolve are adaptive at the gene level through his use of the metaphor of the selfish gene. Genes serve their own selfish interests in the sense that whatever the contributions made by a gene, or set of genes, to an organism’s structure and function would be passed on to the next generation if and only if the gene made its way to the gene pool. Survival of the fittest now had a biological basis. United We Stand, Divided We Fall Charles Darwin did not know that genes were the mechanism through which structures and behaviors evolved, but an important component of his original theory was the notion of survival of the fittest. Darwin was also puzzled by the observation that many individual organisms made themselves less fit so that the group might survive. Subsequent generations of evolutionary biologists realized that even though genes might act as if selfish, the vehicle responsible for the transport of these genes to the gene pool occasionally extended beyond the individual or parent to kin and even to unrelated members of groups. More specifically, in some cases the superorganismal structures formed by social organisms represent naturally selected levels of organization above individual organisms (4). Consider the example of the Emperor penguin (Aptenodytes forsteri). Emperor penguins typically reside near their food source of squid, shoaling fish, and small crustaceans but in early winter they gather into breeding colonies (rookeries) up to 60 miles inland in April and May during the Antarctic winter. They search for their mate from the previous year, and go through a courtship ritual before mating. The female lays only one egg in May or June, which coincides with the start of the bitter Antarctica winter. The Emperor penguins are thought to have developed this unusual winter breeding behavior to permit the chick to grow to independence the following summer, when food is plentiful. Ensuring the chick survives that long is a collective enterprise, with the vehicle responsible for the chick surviving long enough such that it too can reproduce not being solely the mother or the father but also the huddle. The birthing of the egg leaves the mother depleted, so she must return to the seaside to feed while the father assumes responsibility for the incubation of the egg during the winter. An egg from an Emperor penguin will quickly freeze if left exposed to harsh winter conditions of the Antarctica, so the Page | 21 transition of the egg from beneath the warmth and safety of the mother to atop the feet and under a fold of feathered abdominal skin of the father requires a bit of coordination on the part of the two. Even this is not sufficient for the genes of this pair to find their way into the gene pool. The conditions of the Antarctic winters are among the least hospitable on earth, with winter temperatures dipping below -60 degrees Celsius and winds reaching 120 mph. To protect themselves from the wind and cold, the male penguins huddle together, spending much of their time sleeping to conserve energy. In this harsh environment, survival of the chicks depends on the shared warmth and protection of the huddle, not the individual. The group as a whole is more likely to survive if each penguin and chick shares in the warmth and protection of the collective structure, which means selective pressures exist to promote cooperation to maintain the integrity of the huddle. More generally, for species born to a period of utter dependency, the genes that find their way into the gene pool are not defined solely or even mostly by likelihood that an organism will reproduce but by the likelihood that the offspring of the parent will live long enough to reproduce. As in the case of the Emperor penguins, one consequence is that selfish genes evolved through individual-level selection processes to promote social preferences and group processes, including reciprocal social behaviors, that can extend beyond kin relationships (e.g., 5). Examples of such selection processes in humans exist, as well (e.g., 6, 7). The environmental challenges facing Emperor penguins, as daunting as they are, pale by comparison to the complexities facing the human species. Indeed, the social brain hypothesis posits that the social complexities and demands of primate species contributed to the rapid increase in neocortical (i.e., the outer layer of the brain) connectivity and intelligence (8). Warfare among ancestral hunter-gatherers appears to have contributed to group selection for human social behaviors, especially altruistic behaviors (5). As Darwin (1871) noted: A tribe including many members who, from possessing a high degree of the spirit of patriotism, fidelity, obedience, courage, and sympathy, were always ready to aid one another, and to sacrifice themselves for the common good would be victorious over most other tribes; and this would be natural selection. (p. 166) Moreover, deducing better ways to find food, avoid perils, and navigate territories has adaptive value for large mammals, but the complexities of these ecological demands are no match for the complexities of social living (especially in hostile between-group social environments), which include: recognizing ingroup and outgroup members; learning by social observation; recognizing the shifting status of friends and foes; anticipating and coordinating efforts between two or more individuals; using language to communicate, reason, teach, and deceive others; orchestrating relationships, ranging from pair bonds and families to friends, bands, and coalitions; navigating complex social hierarchies, social norms and cultural developments; subjugating self-interests to the interests of the pair bond or social group in exchange for the possibility of long term benefits for oneself or one’s group; recruiting support to sanction Page | 22 individuals who violate group norms; and doing all this across time frames that stretch from the distant past to multiple possible futures (9). Consistent with this hypothesis, measures of sociality in troops of baboons have been found to be highly correlated with infant survival, and cross-species comparisons have shown that the evolution of large and metabolically expensive brains is more closely associated with social than ecological complexity (9). Our survival depends on our connection with others. Born to the most prolonged period of utter dependency of any animal, human infants must instantly engage their parents in protective behavior, and the parents must care enough about their offspring to nurture and protect them. If infants do not elicit nurturance and protection from caregivers, or if caregivers are not motivated to provide such care over an extended period of time, then the infants will perish along with the genetic legacy of the parents (10). Our developmental dependency mirrors our evolutionary heritage. Hunter/gatherers did not have the benefit of natural weaponry, armor, strength, flight, stealth, or speed relative to many other species. Human survival depended on collective abilities, not on individual might. Selfish Genes, Social Brains It is the gene that is obligatorily selfish, not the human brain. Genes that promote behaviors that increase the odds of the genes surviving are perpetuated. One implication of this simple insight is that evolution can be viewed as the competition between genes using individuals and social structures as their temporary vehicles. The genetic constitution of Homo Sapiens in the long run derives not solely from the reproductive success of individuals, but also from the success of their children to reproduce. Hunter/gatherers who did not form social connections and who did not feel a compulsion to return to share their food or defense with their offspring may have been more likely to survive to procreate again, but given the long period of dependency of human infants their offspring may have been less likely to survive to procreate. The result is selection that strongly favors the ability to process information that could contribute to the formation and maintenance of social capacities and connections – that is, a social brain. These social capacities evolved hand in hand with genetic, neural, and hormonal mechanisms to support them because the resulting social behaviors helped humans survive, reproduce, and care for offspring sufficiently long that they too survived to reproduce (11-13). Relative to other animals, the striking development of and increased connectivity within the human cerebral cortex, especially the frontal and temporal regions, are among the key evolutionary developments in this regard. The cerebral cortex is a mantle of between 2.6 to 16 billion neurons with each neuron receiving 10,000 to 100,000 synapses in their dendritic trees (e.g., 14). The expansion of the frontal regions in the human brain contributes to the human capacities for reasoning, planning, performing mental simulations, theory of mind, and thinking about self and others. The temporal regions of the brain, in turn, are involved with aspects of social perception, memory, and communication. The means for guiding behavior through the environment emerged prior to neocortical expansion. Page | 23 The evolutionarily older systems also play a role in human information processing and behavior, albeit in a more rigid and stereotyped fashion. The intricately interconnected neocortical regions of the frontal lobes are involved in self control, which permits the modulation of these older systems and the overriding of organismal hedonistic impulses for the benefit of others (15). Evidence across human history provides overwhelming support for the supposition that humans are fundamentally social creatures (13). Even in contemporary times in which autonomy is revered, the average person has been estimated to spend nearly 80% of waking hours in the company of others, most of which is spent in small talk with known individuals (16). These estimates have been supported in more detailed assessment using the dayreconstruction method to determine how people spend their time and how they experienced events in their lives on a daily basis (17). The results of these daily assessments indicate people spend only 3.4 hrs alone, or approximately 20% of their waking hours. The time spent with friends, relatives, spouse, children, clients, and coworkers is rated on average as more inherently rewarding than the time spent alone (17). Respondents indicate that their most enjoyable activities are intimate relations and socializing – activities that promote bonding and high quality relationships, whereas their least enjoyable activities are commuting and working. These results are consistent with survey data. When asked “what is necessary for happiness?” the majority of respondents rate “relationships with family and friends” as most important (18), although we certainly do not always act like this is most important. It is surprisingly easy to overlook the evident. Noticing the Unusual, Overlooking the Obvious On January 15, 2009, US Airways Flight 1549 departed from New York’s LaGuardia Airport for Charlotte, North Carolina when it struck a flock of geese during takeoff. Both engines were disabled, and the heavy aircraft quickly lost the power it needed to stay aloft, but Capt. Chesley Sullenberger somehow managed a controlled descent into the Hudson River. The media dubbed the ditching of the plane and the survival of all 155 passengers and crew the miracle on the Hudson, and Sullenberger was duly heralded as a hero. The ability to control the descent of an 84-ton plane without engine thrust is not something with which humans are naturally endowed. Sullenberger was not a novice, of course. He is a U.S. Air Force Academy graduate who flew F-4 fighter planes while in the Air Force, has 40 years of flight experience, and holds a commercial glider license and glider instructor rating. As remarkable as was his achievement relative to what one might normally expect in this situation, however, Sullenberger’s efforts were not sufficient for the miracle on the Hudson to be achieved. When Flight 1549 came to a stop in the frigid Hudson River, the passengers and crew scrambled to the wings and inflatable slides of their slowly sinking aircraft. Local commercial vessels from the New York Waterway and Circle Line fleets responded almost immediately, with the first of the vessels reaching the plane within four minutes. The crews of the various vessels worked together to rescue the passengers and crew of Flight Page | 24 1549, and various volunteers and agencies offered medical assistance. These rescue efforts were not motivated by personal or commercial self-interests, and none of the commercial vessel captains was lauded as a hero. Their efforts received less attention because their actions were precisely what we expect of one another. It is the unusual, not the commonplace, that is noticed. On March 13, 1964, Kitty Genovese parked near her home in Kew Gardens, New York, and proceeded to her residence in a small apartment complex. Winston Moseley, a business machine operator who later confessed that his motive was simply to kill a woman, overtook Genovese and stabbed her twice in the back. Genovese screamed, “Oh my God, he stabbed me! Help me!”, a call that was heard by neighbors. When one neighbor shouted at the attacker, “Leave that girl alone,” Moseley ran away. Genovese, who was wounded and bleeding, moved toward the apartment building slowly and alone. Moseley returned approximately 10 minutes later and searched for Genovese. Finding her nearly unconscious in a hallway of the building, he continued his knife attack on her and sexually assaulted her. The entire attack unfolded over about half an hour, and yet no one responded. The first clear call for help to the police did not occur until minutes following the final attack, and Genovese died in an ambulance en route to the hospital. The number of people who were aware of some aspect of the attack was estimated to be from a dozen to more than three dozen. One unidentified neighbor who saw part of the attack was quoted in a New York Times article as saying “I didn’t want to get involved.” (19). The notion that people might not go to the aid of another, even a stranger, in dire need led to public outrage. Decades of research led to the conclusion that the ambiguity of the situation and the diffusion of responsibility were contributing factors. These two news stories illustrate, in very different ways, how invisible forces sculpted by evolution and cultivated by the environment act on our species. When commercial boat captains act against their own financial interests to rescue others on a sinking aircraft, we think nothing of it because we believe it is what any individual in the same situation would naturally do. When observers of a brutal attack do nothing to aid the victim, we are horrified because we believe it goes against who we are as a species. Humans are not motivated solely by self interests but rather we work together and help one another when in need. We survive and prosper in the long term through collective concerns and actions, not by solely selfish pursuits (20). Danger Signals The stories of the sardine ball and the penguin huddle suggest that it is dangerous to be on the social perimeter. Living on the perimeter threatens the lives and genetic legacy of humans, as well. Epidemiological studies have found that social isolation is not only associated with lower levels of happiness and well being but with broad based morbidity and mortality (21). Moreover, humans are such meaningmaking creatures that perceived social isolation is at least as important a predictor of adverse outcomes on human health and well being as is objective social isolation (22). Writers may spend long periods by themselves, but the envisioned readers make this time feel Page | 25 anything but isolated. High school graduates who leave family and friends for the first time to attend college, on the other hand, typically experience intense feelings of social isolation even though they are physically around more people than before they left home. Caspi and colleagues (23) found that perceived social isolation in adolescence and young adulthood predicted how many cardiovascular risk factors (e.g., body mass index, waist circumference, blood pressure, cholesterol) were elevated in young adulthood, and that the number of developmental occasions (i.e., childhood, adolescence, young adulthood) at which participants felt socially isolated predicted the number of elevated risk factors in young adulthood. Perceived social isolation is known more colloquially as loneliness, which in early scientific investigations was depicted as “a chronic distress without redeeming features” (24, p. 15). Loneliness may feel like a painfully miserable, hopeless, and worthless state, but we have found it has a specific structure and a valuable adaptive function. Research on the ways in which people describe themselves when asked the question, “Who are you?”, reveals three basic dimensions (25): (1) a personal, or intimate, self, the “you” of your individual characteristics; (2) a social or relational self, which is who you are in relation to the people closest to you—your spouse, kids, friends, and neighbors; and (3) a collective self, the you that is the member of a certain ethnic group, has a certain national identity, belongs to certain professional or other associations, and a member of the fan club for certain sports teams. Similar to the relational self, this part of the self is social but what makes this self distinct is that these are broader social identities, linked to larger social groups rather than individual members of the groups. When we examined the dimensions underlying loneliness/social connectedness, we found the same three basic dimensions (26): (1) intimate connection/isolation refers to the perceived presence/absence of anyone in your life who affirms you as a valued person; (2) relational connection/isolation refers to the perceived presence/absence of quality friendships or family connections; and (3) collective connection/isolation refers to the perceived presence/absence of a meaningful connection with a group or social stimulus (e.g., school, team) beyond other individuals. When you perceive you are part of a valued group (collective connection), for instance, you may be more inclined to agree with other group members, even on beliefs that may seem irrational, than when you are thinking of yourself as a unique individual. Given that human survival and prosperity depends on inclusion in and participation with a social group, especially in evolutionary time when food was scarce and dangers were common, there is an adaptive benefit to having the strong and aversive response of loneliness when an individual feels his or her social connections might be weakening or broken, just as there is a benefit to having aversive signals for other conditions critical for survival. Hunger, thirst, and pain have evolved as aversive signals to prompt an organism to change their behavior in a way that protects the individual and promotes the likelihood their genes will make their way into the gene pool. The social pain of loneliness has evolved similarly – to serve as a signal that one’s connections Page | 26 to others are weakening and to motivate the repair and maintenance of the connections to others that are needed for our health and well being as for the survival of our genes (27). Physical pain is an aversive signal that evolved to motivate one to take action that minimizes damage to one’s body. Loneliness is an aversive signal that evolved to motivate one to take action that minimizes damage to one’s social body. People differ dispositionally in their sensitivity to the pain of social disconnection (i.e., feelings of loneliness; 28) just as people differ in sensitivity to physical pain. Ostracism or objective isolation in most species is associated with an early death (29). In humans, the chronic feeling of social isolation, even when the person remains among the protective embrace of others, is associated with significant mental and physical disorders (30). Chronic hunger, thirst, and pain can also have deleterious effects for, like loneliness, their adaptive value lies in their effects as acute signals, not as chronic conditions. The opposite of feeling hunger, thirst, pain, or loneliness is feeling normal, and this is the state in which most people exist most of the time. The social connections formed by humans need not be based on genetic similarities. The human species has evolved the capacity for and motivation to form relationships not only with other individuals but also with groups (e.g., a Chicago Cubs or Boston Red Sox fan) and nonhuman entities (e.g., through anthropomorphism, 31). Team spirit and school spirit are familiar notions, and although team or school spirit refers to an invisible influence, it is an invisible influence that is no less open to rigorous scientific inquiry than are the invisible influences of gravity or magnetic flux. In the cases of team and school spirit, this influence represents a specific form of social connection between an individual and an emergent structure. Perceived social connections are abstractions that can transcend time and space. People may feel a connection with their ancestors or family heritage even if they are the only remaining descendant, just as people can perceive personal connections with pets, cars, television characters, celebrities, and unseen spiritual entities with whom they do not actually interact. A potent component of spirituality (that does not depend on a specific religion) is the feeling of connection and purpose that come from forming a relationship with a higher being. A simple byproduct of our selfish genes and social brains may be our search for meaning in and connection with broader organizations or beings. Conclusion In 1939, the astrophysicist Sir Arthur Eddington published a book entitled The philosophy of physical science (32). In it he describes a hypothetical scientist who sought to determine the size of the various fish in the sea. The scientist began by weaving a 2-inch mesh net and setting sail across the seas, repeatedly sampling catches and carefully measuring, recording, and analyzing the results of each catch. After extensive sampling, the scientist concluded that there were no fish smaller than two inches in the sea. The moral of Sir Eddington's analogy is twofold. First, scientific instruments are shaped by people’s intuitive theories of the phenomena to be investigated. Second, once developed, scientific expectations and instruments shape data and theory in ways more powerfully and fundamentally than are often appreciated. Page | 27 What is the relevance of this to the story of the social nature of humankind? Our research findings have led me to believe that we all have made Eddington’s error in the way we have thought about, studied, and tried to deal with an invisible force that motivates us to seek and maintain our connection with others – including the loneliness one feels when we feel important social connections are threatened or absent. Historically, the scientific perspective on loneliness was not only that it was a painful and miserable state, but that it was an aversive state with no redeeming features. All one needs to do is to reflect on the last time one felt terribly lonely, and one can appreciate the seemingly selfevident truth of this characterization. But as Sir Arthur Eddington’s story shows us, the obvious and intuitive can sometimes be very misleading. It is now widely recognized that many structures and processes of the mind operate outside of awareness, with only the end products sometimes reaching awareness. Humans have evolved to seek connections with and validation from other minds, and these social connections represent an important set of invisible forces operating on our brain and biology. The need for social connection extends beyond kin relations and beyond face to face relations to include felt connections with superorganismal entities such as teams, political parties, nations, and God. The unseen forces compelling these connections can be quantified and investigated objectively independent of one’s spiritual beliefs. Underlying these aspirations are selfish genes that have produced a social brain which activates reward regions of the brain when we cooperate effectively with others (33) or punish the perpetrators of social exploitations (34), and which activates the pain matrix in the brain when we feel rejected by others (35). When people feel socially isolated (i.e., lonely) compared to when they do not feel lonely, they are more likely not only to perceive nonhuman objects as humanlike but to believe in the existence of God (31, 36). To understand the full capacity of and forces operating on humans, we need to appreciate not only the memory and computational power of the brain but its capacity for representing, understanding, and connecting with other individuals and with the emergent structures, fictional and real, that the brain can represent. That is, we need to recognize that we have evolved a powerful, meaningmaking social brain and a need for social connection. References 1. Dawkins R. The Selfish Gene. 1976. 2. Williams GC.

Page | 30 From Inclusive Fitness to Spiritual Striving The notion of “selfish genes” (and, by extension, selfish organisms) was popularized in Richard Dawkins’ 1976 book by that title. Not long afterwards, an article appeared in Science that presented evidence that the most vicious members of a warlike tribe in South America had the most wives and children. The underlying notion was one of (genetic) survival of the fittest: Those warriors who were particularly vicious were more likely to contribute their genes to the gene pool. Methodological objections have left this an open question, however, and new evidence now exists that calls this interpretation into question (1): the most aggressive warriors may have more children but they have lower indices of reproductive success than their milder brethren in part perhaps because the most aggressive warriors and their offspring are also more likely to be the targets of revenge killings. These new data are entirely consistent with John Cacioppo’s argument that the content of the human gene pool has more to do with the reproductive success of one’s offspring than one’s own reproductive success. Cacioppo argued further that this genetic selection resulted in a social brain that seeks meaning and connection with individuals and with social entities (e.g., groups) that extend beyond other individuals. In the next chapter, theologian Don Browning also embraces the concept of inclusive fitness and, through the writings of Thomas Aquinas, shows how religion serves the human need for meaning and connection through the ethics they advocate, the congregations they form, the institutions they represent, and the God they serve. In his view, religion serves to extend love and connection beyond kin. He further argues that new developments in the sciences and long-standing traditions in theology constitute fertile ground on which to build new and testable hypotheses regarding our fundamental human nature. 1.

Page | 31 Chapter 3 3 Science, Religion, and a Revived Religious Humanism For over 150 years there has been a vital, and often contentious, dialogue between science and religion. In recent 3 The lead author is Don Browning, Ph.D., the Alexander Campbell Professor of Religious Ethics and the Social Sciences, Emeritus, Divinity School, University of Chicago. He has interests in the relation of the social sciences to religious ethics for the purpose of addressing various challenges facing modern life. His books include Generative Man (1973, 1975; National Book Award Finalist, 1974), Religious Thought and the Modern Psychologies (1987, 2004), the co-authored From Culture Wars to Common Ground: Religion and the American Family Debate (1997, 2000), Christian Ethics and the Moral Psychologies (2006), and Equality and the Family (2007). He co-edited Sex, Marriage, and Family in the World Religions (2006), American Religions and the Family (2006), Children and Childhood in American Religions (2009), and Children and Childhood in World Religions (2009). He is the co-principal investigator with Jean Bethke Elshtain of a Templeton Foundation funded $4,000,000 New Science of Virtue project. In this essay, Browning acknowledges the antagonistic relationship that can be found between science and religion, but he proposes that the dialogue between science and religion can now be conducted on philosophical grounds that promote a new religious humanism that will honor the core ideas of the great religions, refine their view of nature, and increase the values of health, wealth, education, and general wellbeing. years, new energy and fresh public interest have been injected into this conversation. This largely has come about due to the new insights into religion and ethics achieved by collaboration between evolutionary psychology and cognitive and social neuroscience. What are the likely social consequences of this new interest in the relation of science and religion? There are at least three possible answers. One might be the new atheism exemplified by the writings of Richard Dawkins, Daniel Dennett, Sam Harris, and Christopher Hitchens. 1 In this approach, the alleged defective thinking of the world religions is exposed, and a worldview and way of life based strictly on science are offered as replacement. A second option might be the return of a hegemonic dominance of religion over science. However, polarizing rhetoric from advocates for the exclusive interpretive priority of either science or religion has long since ceased to be culturally or academically productive. Instead, through dialogue about common issues, scientific and theological thinkers may pose questions that lead to more sophisticated inquiry in both fields. Confidence in the productive possibilities of reciprocal questioning is a hallmark of the long tradition known as religious humanism. Here I illustrate the potential contribution of religious humanism by bringing recent psychological research into dialogue with the religious concept of love. What would this religious humanism be like? The major world religions would remain visible and viable as religious movements. But the contributions of science would help these religions refine their interests in improving the health, education, wealth, Page | 32 and overall well-being of their adherents. In addition, the sciences would help them refine their grasp of the empirical world about which they are, like humans in general, constantly making judgments, predictions, and characterizations. In my vision, the attitude of scientists toward religion would be first of all phenomenological; they would first attempt to describe and understand religious beliefs, ethics, and rituals in their full historical context. But their interest in explaining some of the conditions that give rise to religious phenomena would not be inhibited by either religion or the wider society. There are several different approaches to phenomenology. The perspective that I recommend follows the “critical hermeneutic phenomenology” of Paul Ricoeur. Ricoeur advocates beginning the study of religion with a phenomenology – a careful description – of the person’s or community’s words, symbols, metaphors, and narratives used to communicate the meaning of a religious experience or practice. This view assumes that we cannot describe experience directly but rather that experience is always mediated by symbols and metaphors. But Ricoeur’s phenomenology does not stop with a description of these meanings. It builds in a secondary place for science and explanation. It seeks through science to give explanatory accounts of the affects and motivations that humans bring to these words, symbols, and metaphors. If scientists followed Ricoeur’s model, they would understand the importance of beginning with description, be hesitant to skip lightly over initial phenomenological meanings, appreciate yet grasp the limits of explanation, and be reluctant to plunge into speculations, such as those of the new scientific atheism, about the ultimate truth or falsity of religious phenomena. 2 On the other hand, the religions themselves can contribute to the sciences. They can do this by offering hypotheses about how social and religious ideas, behaviors, and rituals can shape experience, even neural processes, often for the good but sometimes not. The religions can offer a more generous epistemology and ontology than science is inclined to find useful for the tight explanatory interests of the laboratory or scientific survey. This too might generate new hypotheses for scientific investigation. These would be some of the ground rules for how a dialogue between science and religion might stimulate a revived religious humanism. Religious Humanisms of the Past To speak of a revival suggests that there have been many expressions of religious humanism in the past when some form of science, philosophy, and religion creatively interacted. I will limit myself to speaking primarily about Judaism, Christianity, and Islam. A synthesis between Greek philosophical psychology and Christianity can be found in the use of Stoic theories of desire by the apostle Paul, 3 the presence of Aristotle’s family ethic – with its implicit psycho-biology - in the household codes of Ephesians and I Colossians, 4 and the gospel of John’s identification of Jesus with the Platonic and Stoic idea of the pre-existent “Word.” 5 A more intentional religious humanism can be found in Augustine’s use of the neo-Platonic Plotinus, especially in the philosophical psychology of remembrance developed in his Confessions. 6 But the most dramatic example of a religious Page | 33 humanism that spread simultaneously into Judaism, Christianity, and Islam can be found when the lost texts of Aristotle were discovered, translated, and appropriated by scholars from these three religions who worked at the same tables in Islamic libraries in Spain and Sicily during the ninth and tenth centuries. Richard Rubinstein in his timely book titled Aristotle’s Children (2003) tells the story well. 7 This gave rise to forms of Aristotelian religious humanism in the works of Thomas Aquinas in Christianity, Maimonides in Judaism, and Averroës in Islam. On the American scene, one sees another form of Christian humanism in the synthesis of philosophical pragmatism, with all its influence from Darwin, and expressions of liberal Christianity and the social gospel movement. 8 Religious humanisms have not always flourished and are subject to attacks from both fundamentalists and scientific secularists. They need constant updating and vigorous intellectual development. But at their best, they make it possible for societies to maintain strong religious communities as well as integrating symbolic umbrellas that protect the productive interaction of the scientific disciplines with the wider cultural and religious life. An Example: The Agape, Caritas, and Eros Debate Few words in the English language have such a range of everyday meanings and of serious philosophical and theological consideration as the word love. For this reason, it is an excellent candidate for scientific investigation that has potential benefits for religious practice and everyday life. Although some theologians have sought to create a sharp division between "Christian love" and all other forms of love, the tradition of religious humanism proposes that science clarifies the workings of love in human societies and religion extends the scope of love beyond its most immediate domain of kinship. There are three major tensions in theological discussions of Christian love. They center around the two Greek words agape and eros and the Latin word caritas. A famous book titled Agape and Eros (1953) written by the Swedish theologian Anders Nygren traced the debate through Christian history. 9 Nygren believed that the truly normative and authentic understanding of Christian love is found in the word agape, the Greek word used for Christian love in the New Testament. It refers to a kind of self-giving, even self-sacrificial, love that is only possible by the grace of God. 10 Nygren was particularly interested in arguing that Christian love did not build on what the Greek philosophers called eros. He claimed eros refers to the natural desires of humans to have and unite with the goods of life. This includes the goods of health, wealth, affiliation, and pleasure but it also includes the higher goods of beauty and truth. Nygren’s point, however, was that Christian love does not build on or incorporate eros – the natural aspirational strivings of humans. He believed he found this view of Christian love in the New Testament (especially the writing of the apostle Paul) and Martin Luther, the giant of the Protestant Reformation. Nygren was particularly interested in dismantling the classical medieval Roman Catholic view of Christian love that was often summarized with the English word charity or the Latin word caritas. Why Page | 34 did Nygren oppose the caritas view of Christian love? The answer is that the meaning of love as caritas did exactly what Nygren thought Paul and Luther, his theological heroes, did not do. In the classic Roman Catholic view, love as caritas builds on eros. Caritas was seen to include natural desires for health and affiliation. But the caritas view of love also held that religious education and God’s grace built on and expanded these natural inclinations to entail a self-giving benevolence to others, even strangers and enemies – an idea so central to the concept of Christian love. All of this seemed too naturalistic for Nygren. It seemed to play down the importance of God’s transforming grace. He joined other European neo-orthodox theologians of his day such as Karl Barth and Rudolph Bultmann in cutting off Christian love from eros, 11 which in effect was to cut Christian love from nature and desire – the very things scientists tend to study. Beginning with Nygren’s strong view of agape and the strong supernaturalism of both Nygren and Barth, there was little room in these mid-twentieth century Protestant trends for a productive dialogue between Christian ethics and the new scientific advances in moral psychology, evolutionary psychology, and neuroscience. At the same time, however, breakthroughs in these very disciplines have led to a new reassessment of the Catholic caritas model of Christian love. But before I review in more detail how this model worked, especially in the thought of the great medieval Roman Catholic theologian Thomas Aquinas, let me turn to review some of the moral implications of insights into kin altruism and inclusive fitness emerging today from evolutionary psychology and social neuroscience. Moral Implications of Kin Altruism and Inclusive Fitness As is well known, the idea of inclusive fitness was first put forth in 1964 by William Hamilton. 12 Hamilton’s view of inclusive fitness holds that living beings not only struggle for their individual survival but for the survival of offspring and kin who also carry their genes. Their altruism is likely to be proportional to the percentage of their genes that others carry. This insight was further developed by the concept of parental investment. Ronald Fisher and Robert Trivers (1972) defined it as “any investment by the parent in an individual offspring that increases the offspring’s chance of surviving…at the cost of the parent’s ability to invest in other offspring.” 13 These insights were at the core of the emerging field of sociobiology and were first brought to the wider public attention by E.O. Wilson’s Sociobiology: The New Synthesis (1975). 14 But the moral implications of the concept of inclusive fitness, parental investment, and kin altruism have received competing interpretations. Richard Dawkins in his The Selfish Gene (1976) turned these ideas into a defense
