In this original and provocative account of the evolutionary origins of human communication, Michael Tomasello connects the fundamentally cooperative structure of human communication (initially discovered by Paul Grice) to the especially ...

In the last 60,000 years humans have expanded across the globe and now occupy a wider range than any other terrestrial species. Our ability to successfully adapt to such a diverse range of habitats is often explained in terms of our cognitive ability. Humans have relatively bigger brains and more computing power than other animals and this allows us to figure out how to live in a wide range of environments. Here we argue that humans may be smarter than other (...) creatures, but none of us is nearly smart enough to acquire all of the information necessary to survive in any single habitat. In even the simplest foraging societies, people depend on a vast array of tools, detailed bodies of local knowledge, and complex social arrangements, and often do not understand why these tools, beliefs, and behaviors are adaptive. We owe our success to our uniquely-developed ability to learn from others. This capacity enables humans to gradually accumulate information across generations, and develop well-adapted tools, beliefs, and practices that are too complex for any single individual to invent during their lifetime.

Reactive crying, displayed by children as a response to the distress of another, is described as a precursor of helping and caring. There are several stages during the transition from the innate, reactive cry to the intentional response. Children at the age of 6–14 months are able to control their reactive distress response, yet still respond to the distress of others by displaying distress behavior themselves. Two explanations are discussed. According to one explanation, children are confused about what happens to (...) the self and what happens to the other. This explanation is criticized for being based on misunderstandings of the nature of sensations. An alternative and more promising explanation is derived from kin selection theory. According to this explanation, the development of reactive crying and the transition to caring and helping have been shaped by different forces acting on paternally and maternally derived genes.

Autistic-spectrum conditions and psychotic-spectrum conditions (mainly schizophrenia, bipolar disorder, and major depression) represent two major suites of disorders of human cognition, affect, and behavior that involve altered development and function of the social brain. We describe evidence that a large set of phenotypic traits exhibit diametrically opposite phenotypes in autistic-spectrum versus psychotic-spectrum conditions, with a focus on schizophrenia. This suite of traits is inter-correlated, in that autism involves a general pattern of constrained overgrowth, whereas schizophrenia involves undergrowth. These disorders also (...) exhibit diametric patterns for traits related to social brain development, including aspects of gaze, agency, social cognition, local versus global processing, language, and behavior. Social cognition is thus underdeveloped in autistic-spectrum conditions and hyper-developed on the psychotic spectrum.;>We propose and evaluate a novel hypothesis that may help to explain these diametric phenotypes: that the development of these two sets of conditions is mediated in part by alterations of genomic imprinting. Evidence regarding the genetic, physiological, neurological, and psychological underpinnings of psychotic-spectrum conditions supports the hypothesis that the etiologies of these conditions involve biases towards increased relative effects from imprinted genes with maternal expression, which engender a general pattern of undergrowth. By contrast, autistic-spectrum conditions appear to involve increased relative bias towards effects of paternally expressed genes, which mediate overgrowth. This hypothesis provides a simple yet comprehensive theory, grounded in evolutionary biology and genetics, for understanding the causes and phenotypes of autistic-spectrum and psychotic-spectrum conditions.

This major study examines the most fundamental categories in terms of which we conceive of ourselves, critically surveying the concepts of substance, causation, agency, teleology, rationality, mind, body and person, and elaborating the conceptual fields in which they are embedded. The culmination of 40 years of thought on the philosophy of mind and the nature of the mankind Written by one of the world’s leading philosophers, the co-author of the monumental 4 volume _Analytical Commentary on the Philosophical Investigations_ Uses broad (...) categories, such as substance, causation, agency and power to examine how we think about ourselves and our nature Platonic and Aristotelian conceptions of human nature are sketched and contrasted Individual chapters clarify and provide an historical overview of a specific concept, then link the concept to ideas contained in other chapters.

This major new study by one of the most penetrating and persistent critics of philosophical and scientific orthodoxy, returns to Aristotle in order to examine the salient categories in terms of which we think about ourselves and our nature, and the distinctive forms of explanation we invoke to render ourselves intelligible to ourselves.

Badcock and Crespi have advanced the hypothesis that autism and schizophrenia are caused by imbalanced imprinting in the brain. They argue that an imbalance between the effects of paternally and maternally expressed genes on brain development results in either an extreme paternal (autism) or maternal brain (schizophrenia). In this paper their conceptual model is discussed and criticized since it presupposes an incoherent distinction between observable physical and hidden mental phenomena. An alternative model is discussed that may be more fruitful for (...) investigating the possible role of imprinted genes in the development of social behaviour. The development of crying and reactive crying and behaviours necessary for collaborative action are discussed as a promising research area for understanding the effects of imprinted genes. (shrink)
