Arguments for the autonomy of psychology or other higher-level sciences have often taken the form of denying the possibility of reduction. The form of reduction most proponents and critics of the autonomy of psychology have in mind is theory reduction. Mechanistic explanations provide a different perspective. Mechanistic explanations are reductionist insofar as they appeal to lower-level entities—the component parts of a mechanism and their operations— to explain a phenomenon. However, unlike theory reductions, mechanistic explanations also recognize the fundamental role of organization in enabling mechanisms to engage their environments as units (as well as the role of yet higher-level structures in constraining such engagement). Especially when organization is non-linear, it can enable mechanisms to generate phenomena that are quite surprising given the operations of the components taken in isolation. Such organization must be discovered—it cannot simply be derived from knowledge of lower-level parts and their operations. Moreover, the organized environments in which mechanisms operate must also be discovered. It is typically the higher-level disciplines that have the tools for discovering the organization within and between mechanisms. Although these inquiries are constrained by the knowledge of the parts and operations constituting the mechanism, they make their own autonomous contribution to understanding how a mechanism actually behaves. Thus, mechanistic explanations provide a strong sense of autonomy for higher levels of organization and the inquiries addressing them even while recognizing the distinctive contributions of reductionistic research investigating the operations of the lower level components.

Multiple realization historically mandated the autonomy of psychology, and its principled irreducibility to neuroscience. Recently, multiple realization and its implications for the reducibility of psychology to neuroscience have been challenged. One challenge concerns the proper understanding of reduction. Another concerns whether multiple realization is as pervasive as is alleged. I focus on the latter question. I illustrate multiple realization with actual, rather than hypothetical, cases of multiple realization from within the biological sciences. Though they do support a degree of autonomy for higher levels of explanation and organization, they do not have the dire consequences critics of multiple realization fear. †To contact the author, please write to: Department of Philosophy, University of Cincinnati, P.O.

Although there are many variations on the theme, so much is made of the good of moral autonomy that it is difficult not to suppose that there is everything to be said for being morally autonomous and nothing at all to be said for being morally nonautonomous. However, this view of moral autonomy cannot be made to square with the well-received fact that most people are morally nonautonomous — not, at any rate, unless one is prepared to maintain that most people are irrational in this respect. I am not. Thus, I reject what I take to be the prevailing view of moral autonomy. I argue that it is false that (1) moral autonomy is such that it is rational for every person to prefer being morally autonomous to being morally nonautonomous, but true that (2) moral autonomy is such that if anyone is morally autonomous, then it is rational for him to prefer being morally autonomous to being morally nonautonomous.

I contrast Bickle's new wave reductionismwith other relevant views about explanation across intertheoretic contexts. I then assess Bickle's empirical argument for psychoneural reduction. Bickle shows that psychology is not autonomous from neuroscience, and concludes that at least some versions of nonreductive physicalism are false. I argue this is not sufficient to establish his further claim that psychology reduces to neuroscience. Examination of Bickle's explanations reveals that they do not meet his own reductive standard. Furthermore, there are good empirical reasons to doubt that the cognitive approach to mind should be abandoned. I suggest that the near future will not see a reduction of psychology to neuroscience, so much as a replacement of both sciences by an improved form of neuropsychology.

This paper explores the relationship between psychology and neurobiology in the context of cognitive science. Are the sciences that constitute cognitive science independent and theoretically autonomous, or is there a necessary interaction between them? I explore Fodor's Multiple Realization Thesis (MRT) which starts with the fact of multiple realization and purports to derive the theoretical autonomy of special sciences (such as psychology) from structural sciences (such as neurobiology). After laying out the MRT, it is shown that, on closer inspection, the argument is either circular or self-undermining--the argument either assumes the very autonomy it seeks to demonstrate or the concluded autonomy is contradicted by the theoretical interdependence invoked by the premises of the argument. Next, I explore a concrete example of multiple realization in the explanation of animal behavior: the convergent evolution of jamming avoidance behaviors in three genera of weakly electric fish. Contrary to the image painted by the MRT, the work on these animals involves a high degree of interaction between the various levels of investigation. The fact that our understanding of electric fish behavior involves functional theories and multiple realization without the kind of disunified science that is supposed to follow from such a situation indicates that the mere fact of multiple realization cannot be the basis for an autonomous psychology.

What does it mean to say that the discipline of psychology is autonomous? Jerry Fodor (1998, p. 9) says that ‘a law or theory that figures in bona fide empirical explanations but that is not reducible to a law or theory of physics is ipso facto autonomous’. F-autonomy is irreducibility. The Churchlands mean more than this by autonomy; for them, to regard a discipline as autonomous is to ‘try to conduct the affairs of [that discipline] independently of the affairs of its immediate neighbours, both upward and downward in level’ (Churchland and Churchland, 1996, p. 220). We take it that this is not just a matter of pragmatic choices about conducting research with limited resources; rather, a discipline is autonomous when it is not governed or constrained by other disciplines. In this sense, C-autonomy is independence. On the face of it, the two doctrines are distinct and C-autonomy entails F- autonomy.

This paper examines the notion that psychology is autonomous. It is argued that we need to distinguish between (a) the question of whether psychological explanations are autonomous, and (b) the question of whether the process of psychological discovery is autonomous. The issue is approached by providing a reinterpretation of Robert Cummins's notion of functional analysis (FA). A distinction is drawn between FA as an explanatory strategy and FA as an investigative strategy. It is argued that the identification of functional components of the cognitive system may draw on knowledge about brain structure, without thereby jeopardizing the explanatory autonomy of psychology.
