In an explanation, what does the explaining and what gets explained? What are the relata of the explanation relation? Candidates include: people, events, facts, sentences, statements, and propositions.

Davidson has argued that there can be no laws linking psychological states with physical states. I stress that this argument depends crucially on there being no purely psychological laws. All of this has to do with the holism and indeterminacy of the psychological domain. I criticize this claim by showing how Davidson misconstrues the role of ceteris paribus clauses in psychological explanation. Using a model of how ceteris paribus clauses operate derived from Lakatos, I argue that if Davidson is correct, then there can be no purely physical laws either. This is illustrated with a case from immunology involving interferons. Since there clearly are physical laws, Davidson cannot be correct.

Evolutionary psychology purports to explain human capacities as adaptations to an ancestral environment. A complete explanation of human language or human reasoning as adaptations depends on assessing an historical claim, that these capacities evolved under the pressure of natural selection and are prevalent because they provided systematic advantages to our ancestors. An outline of the character of the information needed in order to offer complete adaptation explanations is drawn from Robert Brandon (1990), and explanations offered for the evolution of language and reasoning within evolutionary psychology are evaluated. Pinker and Bloom's (1992) defense of human language as an adaptation for verbal communication, Robert Nozick's (1993) account of the evolutionary origin of rationality, and Cosmides and Tooby's (1992) explanation of human reasoning as an adaptation for social exchange, are discussed in light of what is known, and what is not known, about the history of human evolution. In each case, though a plausible case is made that these capacities are adaptations, there is not enough known to offer even a semblance of an explanation of the origin of these capacities. These explanations of the origin of human thought and language are simply speculations lacking the kind of detailed historical information required for an evolutionary explanation of an adaptation.

As much as assumptions about mechanisms and mechanistic explanation have deeply affected psychology, they have received disproportionately little analysis in philosophy. After a historical survey of the influences of mechanistic approaches to explanation of psychological phenomena, we specify the nature of mechanisms and mechanistic explanation. Contrary to some treatments of mechanistic explanation, we maintain that explanation is an epistemic activity that involves representing and reasoning about mechanisms. We discuss the manner in which mechanistic approaches serve to bridge levels rather than reduce them, as well as the different ways in which mechanisms are discovered. Finally, we offer a more detailed example of an important psychological phenomenon for which mechanistic explanation has provided the main source of scientific understanding.

Philosophy of Psychology i s an introduction to philosophical problems that arise in the scientific study of cognition and behavior. Jose; Luis Bermúdez introduces the philosophy of psychology as an interdisciplinary exploration of the nature and mechanisms of cognition. He charts out four influential "pictures of the mind" and uses them to explore central topics in the philosophical foundations of psychology, covering all the core concepts and themes found in undergraduate courses in philosophy and psychology, including: · Models of psychological explanation · The nature of commonsense psychology · Arguments for the autonomy of psychology · Fuctionalist approaches to cognition · Computational models of the mind · Neural network modeling · Rationality and mental causation · Perception, action and cognition · The language of thought and the architecture of cognition Philosophy of Psychology: A Contemporary Introduction is a very clear and well-structured textbook from one of the leaders in the field.

The essays in this volume investigate the norms of reason--the standards which contribute to determining whether beliefs, inferences, and actions are rational. Nine philosophers and two psychologists discuss what kinds of things these norms are, how they can be situated within the natural world, and what role they play in the psychological explanation of belief and action. Current work in the theory of rationality is subject to very diverse influences ranging from experimental and theoretical psychology, through philosophy of logic and language, to metaethics and the theory of practical reasoning; this range is well represented here.

Familiar accounts have it that one explains thoughts or actions by showing them to be rational. It is common to find that the standards of rationality presupposed in these accounts are drawn from what would be thought to be aprioristic sources. I advance an argument to show this must be mistaken. But, recent work in epistemology and on rationality takes a less aprioristic approach to such standards. Does the new (psychological or cognitive scientific) realism in accounts of rationality itself significantly improve the prospects for unproblematic forms of rationalizing explanation? Do earlier misgivings about rationalizing explanation ring hollow when the rationality to be attributed is "naturalized"? Answer: while explanation in terms of naturalized rationality would be free of one fatal flaw possessed by explanation in terms of rationality understood in the traditional fashion, it would yet have parallel flaws.
