The ultimate source of explanation in biology is the principle of natural selection. Natural selection means differential reproduction of genes and gene combinations. It is a mechanistic process which accounts for the existence in living organisms of end-directed structures and processes. It is argued that teleological explanations in biology are not only acceptable but indeed indispensable. There are at least three categories of biological phenomena where teleological explanations are appropriate.

A problem that has troubled both neo-Darwinists and neo-Lamarckians is whether instincts involve knowledge. This paper discusses the contributions to this problem of the evolutionary biologist August Weismann and the philosopher Ludwig Wittgenstein. Weismann discussed an empirical homunculus fallacy: Lamarck’s theory mistakenly presupposes a homunculus in the germ cells. Wittgenstein discussed a conceptual homunculus fallacy which applies to Lamarck’s theory: it is mistaken to suppose that knowledge is stored in the brain or DNA. The upshot of these two fallacies is (...) that instincts arise through a neo-Darwinian process but are not cognitions in the sense that they involve knowledge. Although neo-Lamarckians have rightly argued that learning processes may contribute to the development of instincts, their ideas about the role of knowledge in the evolution and development of instincts are mistaken.

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.

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)

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.

The present paper constitutes a development of the position that illness, whether bodily or mental, should be analyzed as an incapacitating failure of bodily or mental capacities, respectively, to realize their functions. The paper undertakes this development by responding to two critics. It addresses first Szasz’s continued claims that (1) physical illness is the paradigm concept of illness and (2) a philosophical analysis of mental illness does not shed any light on the social and legal role of the idea. Then, (...) in reply to Wakefield, the aim is to defend the account as an interpretation of Aristotle and to argue that this Aristotelian view of mental illness is preferable to one that rests on a supposed value free account of human function. More generally the discussion points to the fact that both Wakefield and Szasz rely on a number of metaphysical assumptions about the supposedly empirical nature of medical diagnosis, about the relation between facts and values, and about mind and body (among others), which are open to challenge. In particular the paper indicates an aristotelian approach to the fusion, in the natural world, of so-called facts and values, and the relevance of this fusion to the analysis of the concept of illness. This suggests the debate over distinct conceptions of that concept must both illumine and be illuminated by these deeper metaphysical questions. (shrink)
