Is unethical conduct necessarily irrational? Answering this question requires giving an account of practical reason, of practical good, and of the source or point of wrongdoing. By the time most contemporary philosophers have done the first two, they have lost sight of the third, chalking up bad action to rashness, weakness of will, or ignorance. In this book, Candace Vogler does all three, taking as her guides scholars who contemplated why some people perform evil deeds. In doing so, she sets out to at once engage and redirect contemporary debates about ethics, practical reason, and normativity.

Staged as a limited defense of a standard view of practical reason (an ancestor of contemporary instrumentalist views), Vogler's essay develops Aquinas's remark about three ways an action might be desirable into an exhaustive system for categorizing reasons for acting. Drawing on Elizabeth Anscombe's pioneering work on intention, Vogler argues that one sort (means/end or calculative reasons for acting) sets the terms for all sound work on practical rationality.

She takes up Aquinas's work on evil throughout, arguing that he provides us with a systematic theory of immorality that takes seriously the goods at issue in wrongdoing and the reasons for unethical conduct. Vogler argues that, shorn of its theological context, this theory leaves us with no systematic, uncontroversial way of arguing that wrongdoing is necessarily contrary to reason.


  • It is sometimes better in philosophy not to allow oneself to be distracted by a range of possible objections to this or that aspect of a complex theory that one is developing, but instead to restrict oneself to articulating it as fully and adequately as possible, so that it becomes available as an object of critical discussion. And here Vogler has performed magnificently, drawing first upon Elizabeth Anscombe's for too long unjustly neglected Intention, and supplementing it with arguments that elucidate the notion of a desirability-characterization. She makes excellent use both of Aquinas's three-fold division of good and of some of his discussions of vice and of pleasure. She develops the notion of the benefiting in a way that makes it highly relevant to contemporary discussions. And she elaborates an unusually interesting theory about why and how practical reason has to be calculative. What we are given is a distinctive, well-argued, in some key respects original and beautifully written account of practical reason. I cannot imagine anyone who has involved her or himself in this area of enquiry who would not find it profitable reading, even if it only moved them to redefine and to sharpen their disagreements with the positions taken by the author. It is a very enjoyable book to read.
