There have been various attempts to apply Darwinian evolutionary theory to an understanding of the human condition within psychology and the social sciences. This paper evaluates whether Darwinian Theory can explain human consciousness. Starting with a brief definition of phenomenal consciousness and the central features of evolutionary theory, the paper examines whether random variations in the genome that confer a selective, reproductive advantage can explain both the emergence of consciousness and its varied forms. To inform the discussion, the paper reviews (...) what is known about the conditions for consciousness within the human mind/brain, understood in both structural (neural) terms and functional terms (in terms of human information processing), and concludes that “random variations in the genome” provide no explanatory mechanism for why some neural activities (but not others) are accompanied by consciousness. The paper then evaluates the many functional advantages that have been proposed for various forms of phenomenal consciousness once they emerge, and concludes that, on close examination, phenomenal experiences themselves do not carry out the information processing functions attributed to them, which challenges the Darwinian requirement that they could only have persisted (once emergent) it they enhanced reproductive fitness. The paper turns finally to what can be said about wider distribution of consciousness in non-humans, contrasting discontinuity theories with continuity theories. Discontinuity theories argue for a critical functional transition that “switches on consciousness” while continuity theories argue for a gradual transition in consciousness from unrecognisable to recognisable. All theories accept that there is an intimate, natural relationship of conscious experiences with their associated material forms. Consequently, as the material forms evolve, their associated experiences co-evolve—suggesting an indirect mechanism by which the emergence of species-specific forms of consciousness can be influenced by Darwinian evolution. It also allows a non-reductive understanding of human consciousness within the social sciences. (shrink)

This review summarises why it is difficult for Darwinian evolutionary theory to explain the existence and function of consciousness. It then evaluates whether Humphrey's book Soul Dust overcomes these problems. According to Humphrey, consciousness is an illusion constructed by the brain to enhance reproductive fitness by motivating creatures that have it to stay alive. Although the review entirely accepts that consciousness gives a first-person meaning to existence, it concludes that Humphrey does not give a convincing account of how this can (...) arise from random variations in the genome. Nor does he demonstrate how first-person experiences might enter into or be reducable to third-person functioning. The review concludes that Humphrey's case is unconvincing, and goes on to suggest that an entirely different, non-reductive approach may be required to understand consciousness. (shrink)

During human evolutionary history, there were “trade-offs” between expending time and energy on child-rearing and mating, so both men and women evolved conditional mating strategies guided by cues signaling the circumstances. Many short-term matings might be successful for some men; others might try to find and keep a single mate, investing their effort in rearing her offspring. Recent evidence suggests that men with features signaling genetic benefits to offspring should be preferred by women as short-term mates, but there are trade-offs (...) between a mate's genetic fitness and his willingness to help in child-rearing. It is these circumstances and the cues that signal them that underlie the variation in short- and long-term mating strategies between and within the sexes. Key Words: conditional strategies; evolutionary psychology; fluctuating asymmetry; mating; reproductive strategies; sexual selection. (shrink)

Practically all theories of iconicity are denunciations of its subject matter (for example, those of Goodman, Bierman and the early Eco). My own theory of iconicity was developed in order to save a particular kind of iconicity, pictoriality, from such criticism. In this interest, I distinguished pure iconicity, iconic ground, and iconic sign, on one hand, and primary and secondary iconic signs, on the other hand. Since then, however, several things have happened. The conceptual tools that I created to explain (...) pictoriality have been shown by others to be relevant to linguistic iconicity. On the other hand, semioticians with points of departure different from mine have identified mimicry as it is commonly found in the animal world as a species of iconicity. In the evolutionary semiotics of Deacon, iconicity is referred to in such a general way that it seems to be emptied of all content, while in the variety invented by Donald the term mimesis is used for a particular phase in the evolution of iconic meaning. The aim of this article is to consider to what extent the extension of iconicity theory to new domains will necessitate the development of new models. (shrink)

Previous discussions of the evolution of the self have diverged greatly in their estimates of the date at which the capacity for self-thought emerged, the factors that led self-reflection to evolve, and the nature of the evidence offered to support these disparate conclusions. Beginning with the assumption that human self-awareness involves a set of distinct cognitive abilities that evolved at different times to solve different adaptive problems, we trace the evolution of self-awareness from the common ancestor of humans and apes (...) to the beginnings of culture, drawing upon paleontological, anthropological, biological, and psychological evidence. These data converge to suggest that that modern self-thought appeared just prior to the Middle-Upper Paleolithic transition, approximately 60,000 years ago.Recto running head: Evolution of the Self.

Darwin, Sex and Statusargues that a human sociobiology that mistakes evolutionary theory for theories of psychology and culture is wrong, as are psychologies that could never have evolved or social sciences that posit impossible psychologies. Status develops theories of human self-awareness, cognition, and cultural capacity that are compatible with evolutionary theory. Recurring themes include: the importance of sexual selection in human evolution; our species' preoccupation with self-esteem and relative standing; the individual as an active strategist, regularly revising culturally provided information; (...) and awareness as an impressionmanagement device. Culture is a somewhat structured information pool that itself evolves, often in ways that reduce the genetic fitness of its participants. (shrink)

Altruistic behavior and motivation has traditionally been regarded as a defense mechanism defined by the vicissitudes of instinctual gratification. In this article, we suggest that there exists a substantial body of evidence from the fields of ethology, infant research, and experimental psychology to support the existence of an independently motivated altruism that is nondefensive in nature. We attempt to show how the view of altruism as a universal motivational system stems from the recent developments in evolutionary theory and contributes to (...) our understanding of intrapsychic factors influencing human behavior in general and the process of psychotherapy in particular. It is not our goal to prove the existence of "pure altruism" that can never be derived from selfish motives. Rather, our thesis is that self-oriented and altruistic motivations are equal and essential partners in human evolution and development. It is the optimal balance of these two forces that is necessary for evolutionary advancement and for psychological health. (shrink)

Starting from the concept of Digital Earth, the article questions the effects that Google’s geo-spatial applications have produced on our daily relationship with information, and the way we experience the spaces around us. Its aim is twofold: on the one hand, I intend to examine the implications that bring Google’s digital maps closer to the invention of the print or telescope; on the other hand, I intend to explain, through a medio-anthropological investigation, how the map, as a medium of perception, (...) falls not only de facto, but also de jure, into the field of aesthetics.

The broad character of the arguments used by sociobiologists is assessed, particularly in relation to criticisms coming from anthropology. The implications of sociobiology for theology are developed with respect to the general impact of evolutionary ideas, the reductionist assumptions of sociobiologists, whether or not “survival” can be a value, and more holistic accounts of the physical and biological grounding of the mental and spiritual lives of human beings.

Though I have not found enough of the latter to test out this bromide, I am sensible of the value bestowed by colleagues who have taken such exacting care in analyzing my arguments. While their incisive observation and hard objections threaten to leave an extinct theory, I hope the reader will rather judge it one strengthened by adversity. Let me initially expose the heart of my argument so as to make obvious the shocks it must endure. I ask the reader (...) to grant that altruistic behavior can be empirically justified, that is, to allow that we have evolved under the aegis of kin and group selection (or comparably effective mechanisms) to heed the community welfare, to be moved to aid the distressed even at..

After stressing the shortcomings of Darwinian accounts of self-consciousness and knowledge - i.e. in terms of their survival value - Anthony O'Hear presents Peirce's metaphysical hypotheses on cosmic evolution as an alternative approach that avoids those shortcomings. Although O'Hear does not straightforwardly defend Peirce's views, his argument suggests that only some teleological account of self-consciousness and knowledge is reasonable. The argument, though correct, is not enough to establish the metaphysical point O'Hear defends. Before developing his metaphysical ideas, Peirce's rejection of (...) natural selection as an explanation for every phenomenon brought him to consider the more appropriate question of how natural selection could give rise to a different kind of evolution. This involved outlining an evolutionary account of the origin of self-consciousness and of the mechanisms of belief fixation. The point is not one about Peirce, of course, but about the relationship between, on the one hand, biological and, on the other, psychological and cultural phenomena. (shrink)
