A novel account of the evolution of language and the cognitive capacities on which language depends.In From Signal to Symbol, Ronald Planer and Kim Sterelny propose a novel theory of language: that modern language is the product of a long series of increasingly rich protolanguages evolving over the last two million years. Arguing that language and cognition coevolved, they give a central role to archaeological evidence and attempt to infer cognitive capacities on the basis of that evidence, which they link in turn to communicative capacities.  Countering other accounts, which move directly from archaeological traces to language, Planer and Sterelny show that rudimentary forms of many of the elements on which language depends can be found in the great apes and were part of the equipment of the earliest species in our lineage. After outlining the constraints a theory of the evolution of language should satisfy and filling in the details of their model, they take up the evolution of words, composite utterances, and hierarchical structure. They consider the transition from a predominantly gestural to a predominantly vocal form of language and discuss the economic and social factors that led to language. Finally, they evaluate their theory in terms of the constraints previously laid out.

An argument that achieving millennial life spans or monumental intellects will destroy values that give meaning to human lives.

A philosophical account of human nature that defends the concept against dehumanization, Darwinian, and developmentalist challenges.Human nature has always been a foundational issue for philosophy. What does it mean to have a human nature? Is the concept the relic of a bygone age? What is the use of such a concept? What are the epistemic and ontological commitments people make when they use the concept? In What's Left of Human Nature? Maria Kronfeldner offers a philosophical account of human nature that defends the concept against contemporary criticism. In particular, she takes on challenges related to social misuse of the concept that dehumanizes those regarded as lacking human nature (the dehumanization challenge); the conflict between Darwinian thinking and essentialist concepts of human nature (the Darwinian challenge); and the consensus that evolution, heredity, and ontogenetic development result from nurture and nature.After answering each of these challenges, Kronfeldner presents a revisionist account of human nature that minimizes dehumanization and does not fall back on outdated biological ideas. Her account is post-essentialist because it eliminates the concept of an essence of being human; pluralist in that it argues that there are different things in the world that correspond to three different post-essentialist concepts of human nature; and interactive because it understands nature and nurture as interacting at the developmental, epigenetic, and evolutionary levels. On the basis of this, she introduces a dialectical concept of an ever-changing and "looping” human nature. Finally, noting the essentially contested character of the concept and the ambiguity and redundancy of the terminology, she wonders if we should simply eliminate the term "human nature” altogether.

Why the "nature versus nurture" debate persists despite widespread recognition that human traits arise from the interaction of nature and nurture.

Addresses the question of localization: whether psychological processes can be defined and isolated in a way that permits them to be associated with particular brain regions.

Paul Thagard proposes a general theory of coherence as the satisfaction of multiple interacting constraints, and discusses the theory's numerous psychological and philosophical applications.

The nature/nurture debate is not dead. Dichotomous views of development still underlie many fundamental debates in the biological and social sciences. Developmental systems theory (DST) offers a new conceptual framework with which to resolve such debates. DST views ontogeny as contingent cycles of interaction among a varied set of developmental resources, no one of which controls the process. These factors include DNA, cellular and organismic structure, and social and ecological interactions. DST has excited interest from a wide range of researchers, from molecular biologists to anthropologists, because of its ability to integrate evolutionary theory and other disciplines without falling into traditional oppositions.The book provides historical background to DST, recent theoretical findings on the mechanisms of heredity, applications of the DST framework to behavioral development, implications of DST for the philosophy of biology, and critical reactions to DST.

Essays from a range of disciplinary perspectives show the central role that cooperation plays in structuring our world.

A psychologist and a philosopher with opposing viewpoints discuss the extent to which it is possible to report accurately on our own conscious experience, considering both the reliability of introspection in general and the particular self-reported inner experiences of "Melanie," a subject interviewed using the Descriptive Experience Sampling method.Can conscious experience be described accurately? Can we give reliable accounts of our sensory experiences and pains, our inner speech and imagery, our felt emotions? The question is central not only to our humanistic understanding of who we are but also to the burgeoning scientific field of consciousness studies. The two authors of Describing Inner Experience disagree on the answer: Russell Hurlburt, a psychologist, argues that improved methods of introspective reporting make accurate accounts of inner experience possible; Eric Schwitzgebel, a philosopher, believes that any introspective reporting is inevitably prone to error. In this book the two discuss to what extent it is possible to describe our inner experience accurately. Hurlburt and Schwitzgebel recruited a subject, "Melanie," to report on her conscious experience using Hurlburt's Descriptive Experience Sampling method (in which the subject is cued by random beeps to describe her conscious experience). The heart of the book is Melanie's accounts, Hurlburt and Schwitzgebel's interviews with her, and their subsequent discussions while studying the transcripts of the interviews. In this way the authors' dispute about the general reliability of introspective reporting is steadily tempered by specific debates about the extent to which Melanie's particular reports are believable. Transcripts and audio files of the interviews will be available on the MIT Press website. Describing Inner Experience? is not so much a debate as it is a collaboration, with each author seeking to refine his position and to replace partisanship with balanced critical judgment. The result is an illumination of major issues in the study of consciousness—from two sides at once.

An analysis of the cognitive consequences of diminished contact with nature examines the relationship between how people think about the natural world and how they act on it, and how these are affected by cultural differences.

Moral thinking pervades our practical lives, but where did this way of thinking come from, and what purpose does it serve? Is it to be explained by environmental pressures on our ancestors a million years ago, or is it a cultural invention of more recent origin? In The Evolution of Morality, Richard Joyce takes up these controversial questions, finding that the evidence supports an innate basis to human morality. As a moral philosopher, Joyce is interested in whether any implications follow from this hypothesis. Might the fact that the human brain has been biologically prepared by natural selection to engage in moral judgment serve in some sense to vindicate this way of thinking—staving off the threat of moral skepticism, or even undergirding some version of moral realism? Or if morality has an adaptive explanation in genetic terms—if it is, as Joyce writes, "just something that helped our ancestors make more babies"—might such an explanation actually undermine morality's central role in our lives? He carefully examines both the evolutionary "vindication of morality" and the evolutionary "debunking of morality," considering the skeptical view more seriously than have others who have treated the subject.Interdisciplinary and combining the latest results from the empirical sciences with philosophical discussion, The Evolution of Morality is one of the few books in this area written from the perspective of moral philosophy. Concise and without technical jargon, the arguments are rigorous but accessible to readers from different academic backgrounds. Joyce discusses complex issues in plain language while advocating subtle and sometimes radical views. The Evolution of Morality lays the philosophical foundations for further research into the biological understanding of human morality.
