Thomist Realism and the Linguistic Turn

Philosophers will be richly rewarded by reading John OCallaghans new book, Thomistic Realism and the Linguistic Turn. Based on his broad knowledge of Aristotle and Aquinas, OCallaghan provides not only an excellent treatment of Aquinass epistemology but also a superb demonstration of just how Aquinas might contribute to contemporary debates. Traditionally, the camps of realism and idealism fiercely engaged one another in the field of epistemology. Thomists participated in confronting idealism from their unique realist position. Post-Wittgenstein, the conflict has been dominated by a form of epistemology that grounds all knowledge in linguistic practice. Since Thomists work in a textual and historical mode, their response to the technical approach of the analytic philosophy in which most of the linguistic epistemologists write has been slow in coming. OCallaghan expertly closes that gap by successfully bringing together these fields.
