Philosophy as Therapy: An Interpretation and Defense of Wittgenstein's Later Philosophical Project

This book presents an account and defense of Wittgenstein's later philosophy emphasizing its therapeutic character. Peterman argues that any therapeutic philosophy must present an account of human health, a related account of the mechanisms of health and illness, and finally an account of how philosophy can bring someone from a state of illness to health. In light of this general model, he presents an interpretation of Wittgenstein's therapeutic project that emphasizes the continuity between it and the earlier ethical project of the Tractatus. The book confronts the problem of continuity by arguing that the earlier ethical goal of coming into agreement with the world as such is replaced in the later views by the therapeutic goal of coming into agreement with forms of life. In the course of the argument, Peterman challenges standard interpretations of Wittgenstein's project and standard modes of criticizing and defending it. The book also contributes to contemporary philosophical discussion by showing why we should take seriously the project of philosophical therapy.
