This 2001 book offers an examination of functional explanation as it is used in biology and the social sciences, and focuses on the kinds of philosophical presuppositions that such explanations carry with them. It tackles such questions as: why are some things explained functionally while others are not? What do the functional explanations tell us about how these objects are conceptualized? What do we commit ourselves to when we give and take functional explanations in the life sciences and the social sciences? McLaughlin gives a critical review of the debate on functional explanation in the philosophy of science. He discusses the history of the philosophical question of teleology, and provides a comprehensive review of the post-war literature on functional explanation. What Functions Explain provides a sophisticated and detailed Aristotelian analysis of our concept of natural functions, and offers a positive contribution to the ongoing debate on the topic.

One result of recent discussions on the notion of function is that the appeal to the function of something in order to explain why it is there and what it is, presupposes (willingly or not) that some system particularly relevant to the function bearer has a good. Some recent analyses of what it means to have a good trace having a good back to having a function. Two such attempts are examined and compared to a more traditional analysis. An anachronistic version of Aristotle, involving the self-production of the beneficiary, is recommended as a better starting point for a naturalistic reconstruction of the subject of benefit.
