Peter Weigel is Associate Professor of Philosophy at Washington College in Maryland. He is the author of Aquinas on Divine Simplicity (2008).

'Book length studies of the 'Five Ways' are rare, so this book fills a definite gap in the literature on Aquinas and does so very well.  Weigel explains in detail what the Ways argue and how other texts by Aquinas are relevant to understanding their content and function in the Summa Theologiae. He also documents a range of published criticisms of the Ways while commenting on them in a judicious and professional manner.' Brian Davies, Fordham University
