Richard J. Regan is Professor of Political Science, Fordham University.
"Those approaching Aquinas from the side of philosophy, and for the first time, have been done a great service by Richard Regan's selective translation of the first part (prima pars) and the first part of the second part (prima secundae) of the Summa Theologiae. By focusing on the questions raised and answers given by Aquinas (and including only the most salient objections and replies), Regan reveals Thomas as a great dialectician, grappling with issues of perennial philosophical interest. Regan's general introduction and chapter introductions together enable the reader to see the point and power of Aquinas' discussions." -- John Haldane, University of St Andrews.
