It is, no doubt, the best we have.""- Thomist;""Both Thomistic scholars and analytic phi- losophers interested in theories of human action and accountability will find this book a welcome addi- tion to their libraries. Truly a substantive addition to both Thomistic scholarship and the ongoing analytic investigation into human action and responsible agency.""- American Catholic Philosophical Quarterly;""A first-rate book...Brock's lucid and illuminating analysis offers much of value to both intellecutal historians and theologians, as well as philosophers.""- Theological Studies;""A tremendously successful exposition of Aquinas, which brings him into conversation with contemporary and analytic philosophy in a mutually illuminating way. Action and Conduct is so thorough and so lucid that no students of Aquinas or of contemporary action theory can afford to neglect it.""- Modern Theology
