Draws on a broad range of scientific evidence to theorize an evolutionary basis for religion, considering how religion may have served as an essential component of early society survival and that the brain may be inherently inclined toward religious behavior.

Did Newton "unweave the rainbow" by reducing it to its prismatic colors, as Keats contended? Did he, in other words, diminish beauty? Far from it, says Dawkins--Newton's unweaving is the key too much of modern astronomy and to the breathtaking poetry of modern cosmology. Mysteries don't lose their poetry because they are solved: the solution often is more beautiful than the puzzle, uncovering deeper mystery. (The Keats who spoke of "unweaving the rainbow" was a very young man, Dawkins reminds us.) (...) With the wit, insight, and spellbinding prose that have made his books worldwide bestsellers, Dawkins addresses the most important and compelling topics in modern science, from astronomy and genetics to language and virtual reality, and combines them in a landmark statement of the human appetite for wonder. This is the book that Richard Dawkins was meant to write: a brilliant assessment of what science is (and what it isn't), a tribute to science "not because it is useful (though it is), but but because it is uplifting, in the same way as the best poetry is uplifting.".

This paper argues that there is a general constraint on the evolution of culture. This constraint – what I am calling the Fundamental Constraint – must be satisfied in order for a cultural system to be adaptive. The Fundamental Constraint is this: for culture to be adaptive there must be a positive correlation between the fitness of cultural variants and their fitness impact on the organisms adopting those variants. Two ways of satisfying the Fundamental Constraint are introduced, structural solutions and (...) evaluative solutions. Because of the limitations on these solutions, this constraint helps explain why there is not more culture in nature, why the culture that does exist has the form it has, and why complex, cumulative culture is restricted to the human species.

This article offers a general definition of self-knowledge that embraces all forms and levels of self-knowledge in animals and humans. It is hypothesized that various levels of self-knowledge constitute an ordinal scale such that each species in a lineage displays the forms of self-knowledge found in related species as well as new forms it and its sister species may have evolved. Likewise, it is hypothesized that these various forms of levels of self-knowledge develop in the sequence in which they evolved. (...) Finally, a general hypothesis for the functional significance of self-knowledge is proposed along with subhypotheses regarding the adaptive significance of various levels of self-knowledge in mammals including human and nonhuman primates. The general hypothesis is that self-knowledge serves as a standard for assessing the qualities of conspecifics compared to those of the self. Such assessment is crucial to deciding among alternative reproductive and subsistence strategies. The qualities that are assessed, which vary across taxa, range from the size and strength of the self to its mathematical or musical abilities. This so-called assessment model of self-knowledge is based on evolutionary biological models for social selection and the role of assessment in animal communication. (shrink)

Save for Anthropologists, few social scientists have been among the participants in the discussions about the appropriate structure of a ‘Universal Darwinism’. Yet evolutionary theorizing about cultural, social, and economic phenomena has a long tradition, going back well before Darwin. And over the past quarter century significant literatures have grown up concerned with the processes of change operating on science, technology, business organization and practice, and economic change more broadly, that are explicitly evolutionary in theoretical orientation. In each of these (...) fields of study, the broad proposition put forth by Darwin that change proceeds through a process involving variation, systematic selection, renewed variation... has proved both persuasive and powerful. On the other hand, the evolutionary processes involved in these areas differ in essential ways from those we now know are operative in the evolution of biological species. The objective of this essay is to highlight those differences, which a ‘Universal Darwinism’ needs to encompass, if it is to be broad enough to be a theory that is applicable to the evolution of human cultures as well as evolution in biology.

Critics of Darwinian cultural evolution frequently assert that whereas biological evolution is blind and undirected, cultural change is directed or guided by people who possess foresight, thereby invalidating any Darwinian analysis of culture. Here I show this argument to be erroneous and unsupported in several respects. First, critics commonly conflate human foresight with supernatural clairvoyance, resulting in the premature rejection of Darwinian cultural evolution on false logical grounds. Second, the presence of foresight is perfectly consistent with Darwinian evolution, and is (...) found in biology, in the form of open, teleonomic processes such as genetically-biased behavioural learning. Finally, empirical evidence from the social sciences suggests that cultural change appears far less guided and directed, and human foresight far less accurate, than is commonly assumed. (shrink)

. Humans can be described as existing somewhere on a descriptive continuum between the poles expressed by the metaphors “humans are machines” and “humans are animals.” Arguments for these metaphors are examined, and the metaphors are rejected as absolute descriptions of humans. After a brief examination of the nature of metaphor, all metaphors are discovered to mediate between biological and cultural evolution. Contrary to the reductionist program of sociobiologists, religious metaphors that generate transcendent meaning offer a legitimate description of humans.

It has often been thought, and has recently been argued, that one of the most profound impacts of Darwin's theory of evolution is the threat that it poses to the very possibility of living a meaningful, and therefore worthwhile, life. Three attempts to ground the possibility of a meaningful life are considered. The first two are compatible with an exclusively Darwinian worldview. One is based on the belief that Darwinian evolution is, in some sense, progressive; the other is based on (...) the belief that the natural world is a thing of value and hence, that our lives are lived in the presence of value. The third is based on a belief in providence, and holds that we must transcend the exclusively Darwinian worldview if we are to find meaning. All three are, for different reasons, rejected. The conclusion reached is that, contrary to what has often been thought and recently argued, the impact of Darwin's theory is precisely to liberate us to lead the most meaningful of lives. (shrink)

The last century has witnessed a succession of revolutionary transformations in the discipline of biology. The rapid expansion of our understanding of life and its nature has however had curiously little impact on the way that questions about life and its significance have been discussed by philosophers. This paper explores the answers that biology provides to central questions about our existence, and examines why the substitution of causal explanations for teleological ones appears natural and satisfying in the case of physical (...) theory, but meets widespread resistance in the case of biology.

Science undermines the certitude of non‐naturalistic answers to the question of whether human life has meaning. I explore whether evolution can provide a naturalistic basis for existential meaning. Using the work of philosopher Daniel Dennett and scientist Ursula Goodenough, I argue that evolution is the locus of the possibility of meaning because it has produced intentionality, the matrix of consciousness. I conclude that the question of the meaning of human life is an existentialist one: existential meaning is a product of (...) the individual and collective tasks human beings undertake. (shrink)

Primordial emotions are the subjective element of the instincts which are the genetically programmed behaviour patterns which contrive homeostasis. They include thirst, hunger for air, hunger for food, pain and hunger for specific minerals etc.There are two constituents of a primordial emotion—the specific sensation which when severe may be imperious, and the compelling intention for gratification by a consummatory act. They may dominate the stream of consciousness, and can have plenipotentiary power over behaviour.It is hypothesized that early in animal evolution (...) complex reflex mechanisms in the basal brain subserving homeostatic responses, in concert with elements of the reticular activating system subserving arousal, melded functionally with regions embodied in the progressive rostral development of the telencephalon. This included the emergent limbic and paralimbic areas, and the insula. This phylogenetically ancient organization subserved the origin of consciousness as the primordial emotion, which signalled that the organisms existence was immediately threatened. Neuroimaging confirms major activations in regions of the basal brain during primordial emotions in humans. The behaviour of decorticate humans and animals is discussed in relation to the possible existence of primitive awareness.Neuroimaging of the primordial emotions reveals that rapid gratification of intention by a consummatory act such as ingestion causes precipitate decline of both the initiating sensation and the intention. There is contemporaneous rapid disappearance of particular regions of brain activation which suggests they may be part of the jointly sufficient and severally necessary activations and deactivations which correlate with consciousness [Crick, F. & Koch, C. . A framework for consciousness. NatureNeuroscience,6, 119–126]. (shrink)

This provocative text considers whether evolutionary explanations can be used to clarify some of life’s biggest questions. Examines topics of race, sex, gender, the nature of language, religion, ethics, knowledge, consciousness and ultimately, the meaning of life Each chapter presents a main topic, together with discussion of related ideas and arguments from various perspectives Addresses questions such as: Did evolution make men and women fundamentally different? Is the concept of race merely a social construction? Is morality, including universal human rights, (...) a mass delusion? Can religion and evolution really be harmonized? Does evolution render life meaningless? Written in a clear and informative style, with helpful references for further reading and research. (shrink)

Nozick analyzes fundamental issues, such as the identity of the self, knowledge and skepticism, free will, the foundations of ethics, and the meaning of life.

One of the most influential works of this century, The Myth of Sisyphus and Other Essays is a crucial exposition of existentialist thought. Influenced by works such as Don Juan and the novels of Kafka, these essays begin with a meditation on suicide; the question of living or not living in a universe devoid of order or meaning. With lyric eloquence, Albert Camus brilliantly posits a way out of despair, reaffirming the value of personal existence, and the possibility of life (...) lived with dignity and authenticity.

This ambitious, interdisciplinary book seeks to explain the origins of religion using our knowledge of the evolution of cognition. A cognitive anthropologist and psychologist, Scott Atran argues that religion is a by-product of human evolution just as the cognitive intervention, cultural selection, and historical survival of religion is an accommodation of certain existential and moral elements that have evolved in the human condition.

Through a series of essays, the author discusses the conflict between cultural and biological evolution, covering intelligent design, gender differences, and the meaning of life while offering insight into the ethical aspects of civilization.

Refinements in Darwin’s theory of the origin of a moral sense create a framework equipped to organize and integrate contemporary theory and research on morality. Morality originated in deferential, cooperative, and altruistic ‘‘social instincts,’’ or decision-making strategies, that enabled early humans to maximize their gains from social living and resolve their conflicts of interest in adaptive ways. Moral judgments, moral norms, and conscience originated from strategic interactions among members of groups who experienced confluences and conflicts of interest. Moral argumentation buttressed (...) by moral reasoning is equipped to generate universal and impartial moral standards. Moral beliefs and standards are products of automatic and controlled information-processing and decision making mechanisms. To understand how people make moral decisions, we must understand how early evolved mechanisms in the old brain and recently evolved mechanisms in the new brain are activated and how they interact. Understanding what a sense of morality is for helps us understand what it is. (shrink)

To properly understand behavior, we must obtain both ultimate and proximate explanations. Put briefly, ultimate explanations are concerned with why a behavior exists, and proximate explanations are concerned with how it works. These two types of explanation are complementary and the distinction is critical to evolutionary explanation. We are concerned that they have become conflated in some areas of the evolutionary literature on human behavior. This article brings attention to these issues. We focus on three specific areas: the evolution of (...) cooperation, transmitted culture, and epigenetics. We do this to avoid confusion and wasted effort—dangers that are particularly acute in interdisciplinary research. Throughout this article, we suggest ways in which misunderstanding may be avoided in the future. (shrink)
