The essays were written by faculty, undergraduate philosophy majors, and graduate students who have taught or led discussions on philosophy in prison; the essays also represent the personal reflections of incarcerated men who have studied philosophy in prison. . . .The varied essays may be organized into the following groups: theoretical reflections on the contributions of certain philosophers (Hegel, Foucault, Kant, and Davis), proposals for reforming the system of mass incarceration in the US, reflections by imprisoned men, critiques of the extreme misogyny in men’s prisons, and the role of philosophy in prison. Of all of the essays, the personal reflections concerning the impact of philosophy on the lives and experiences of incarcerated men were the most moving and powerful. Though the book considers the important transformative role of philosophy in prison, other studies point to the greater importance of college in prison programs in reducing recidivism rates. Summing Up: Recommended. Upper-division undergraduates through researchers/faculty.
