The discussions and debates are as often between a medieval and an ancient Greek philosopher as between contemporaries, and Bosley and Tweedale (both emeritus philosophy, U. of Alberta) think discourse of both kinds is the best framework within which to understand the ideas being presented. Their reader for either introductory or more advanced courses addresses such themes as determinism, free will, and divine foreknowledge; universals and particulars; and sin and sex. No date is cited for the first edition. There is no index. Annotation ©2007 Book News, Inc., Portland, OR (booknews.com)
