The view that organisms deserve moral respect because they have their own purposes is often grounded in a specification of the biological functions that the organism has. One way to identify such functions, adopted by Gary Varner, is to determine the etiology of some behavior based on the evolution of the structures enabling it. This view suffers from some unacceptable problems, including that some organisms with profound defects will by definition have a welfare interest in their defects. For example, this (...) view entails that the patented oncomice, intentionally engineered and bred for a genetic defect that leads to extremely high incidence of cancer, would have a welfare interest in the development of tumors. The systems-based theory of biological functions, which refers not to the evolution of structures but rather to their role in the organism, escapes these problems, and shows how a theory of an organism’s welfare interest in its purposes can be grounded in a sound naturalistic approach. This approach also has some fruitful corollaries, including an elegant theory of why species may require special moral regard. (shrink)

The paper explores the distinction between two doctrines, both of which inform theory construction in much of modern cognitive psychology: the representational theory of mind and the computational theory of mind. According to the former, propositional attitudes are to be construed as relations that organisms bear to mental representations. According to the latter, mental processes have access only to formal (nonsemantic) properties of the mental representations over which they are defined.The following claims are defended: (1) That the traditional dispute between (...) “rational” and “naturalistic” psychology is plausibly viewed as an argument about the status of the computational theory of mind. Rational psychologists accept a formality condition on the specification of mental processes; naturalists do not. (2) That to accept the formality condition is to endorse a version of methodological solipsism. (3) That the acceptance of some such condition is warranted, at least for that part of psychology which concerns itself with theories of the mental causation of behavior. This is because: (4) such theories require nontransparent taxonomies of mental states; and (5) nontransparent taxonomies individuate mental states without reference to their semantic properties. Equivalently, (6) nontransparent taxonomies respect the way that the organism represents the object of its propositional attitudes toitself, and it is this representation which functions in the causation of behavior.The final section of the paper considers the prospect for a naturalistic psychology: one which defines its generalizations over relations between mental representations and their environmental causes, thus seeking to account for the semantic properties of propositional attitudes. Two related arguments are proposed, both leading to the conclusion that no such research strategy is likely to prove fruitful. (shrink)

In this paper I defend an etiological theory of biological functions (according to which the proper function of a trait is the effect for which it was selected by natural selection) against three objections which have been influential. I argue, contrary to Millikan, that it is wrong to base our defense of the theory on a rejection of conceptual analysis, for conceptual analysis does have an important role in philosophy of science. I also argue that biology requires a normative notion (...) of a "proper function", and that a normative notion is not ahistorical. (shrink)

Biological functions are dispositions or effects a trait has which explain the recent maintenance of the trait under natural selection. This is the "modern history" approach to functions. The approach is historical because to ascribe a function is to make a claim about the past, but the relevant past is the recent past; modern history rather than ancient.

What rational justification is there for conceiving of all living things as possessing inherent worth? In _Respect for Nature_, Paul Taylor draws on biology, moral philosophy, and environmental science to defend a biocentric environmental ethic in which all life has value. Without making claims for the moral rights of plants and animals, he offers a reasoned alternative to the prevailing anthropocentric view--that the natural environment and its wildlife are valued only as objects for human use or enjoyment. _Respect for Nature_ (...) provides both a full account of the biological conditions for life--human or otherwise--and a comprehensive view of the complex relationship between human beings and the whole of nature. This classic book remains a valuable resource for philosophers, biologists, and environmentalists alike--along with all those who care about the future of life on Earth. A new foreword by Dale Jamieson looks at how the original 1986 edition of _Respect for Nature_ has shaped the study of environmental ethics, and shows why the work remains relevant to debates today.

Function and teleology can be naturalized either by reference to systems with a particular type of organization or by reference to a particular kind of history. As functions are generally ascribed to states or traits according to their current role and regardless of their origin, etiological accounts are inappropriate. Here, I offer a systems-theoretical interpretation as a new version of an organizational account of functionality, which is more comprehensive than traditional cybernetic views and provides explicit criteria for empirically testable function (...) ascriptions. I propose, that functional states, traits or items are those components of a complex system, which are under certain circumstances necessary for their self-re-production. I show, how this notion can be applied in intra- and trans-generational function ascriptions in biology, how it can deal with the problems of multifunctionality and functional equivalents, and how it relates to concepts like fitness and adaptation. Finally, I argue that most intentional explanations can be treated as functional explanations. (shrink)

This collection of essays serves both as an introduction to Ruth Millikan’s much-discussed volume Language, Thought, and Other Biological Categories and as an extension and application of Millikan’s central themes, especially in the philosophy of psychology. The title essay discusses meaning rationalism and argues that rationality is not in the head, indeed, that there is no legitimate interpretation under which logical possibility and necessity are known a priori. In other essays, Millikan clarifies her views on the nature of mental representation, (...) explores whether human thought is a product of natural selection, examines the nature of behavior as studied by the behavioral sciences, and discusses the issues of individualism in psychology, psychological explanation, indexicality in thought, what knowledge is, and the realism/antirealism debate.

The etiological approach to ‘proper functions’ in biology can be strengthened by relating it to Robert Cummins' general treatment of function ascription. The proper functions of a biological trait are the functions it is assigned in a Cummins-style functional explanation of the fitness of ancestors. These functions figure in selective explanations of the trait. It is also argued that some recent etiological theories include inaccurate accounts of selective explanation in biology. Finally, a generalization of the notion of selective explanation allows (...) an analysis of the proper functions of human artifacts. (shrink)

This book offers a powerful response to what Varner calls the "two dogmas of environmental ethics"--the assumptions that animal rights philosophies and anthropocentric views are each antithetical to sound environmental policy. Allowing that every living organism has interests which ought, other things being equal, to be protected, Varner contends that some interests take priority over others. He defends both a sentientist principle giving priority to the lives of organisms with conscious desires and an anthropocentric principle giving priority to certain very (...) inclusive interests which only humans have. He then shows that these principles not only comport with but provide significant support for environmental goals. (shrink)

In this adventurous contribution to the project of combining philosophy and biology to understand the mind, Carolyn Price investigates what it means to say that mental states--like thoughts, wishes, and perceptual experiences--are about things in the natural world. Her insight into this deep philosophical problem offers a novel teleological account of intentional content, grounded in and shaped by a carefully constructed theory of functions. Along the way she defends her view from recent objections to teleological theories and indicates how it (...) might be applied to notable problems in the philosophy of mind. (shrink)
