Thomas Aquinas (1225-74) was an Italian philosopher and Dominican friar. Ralph McInerny is Professor of Medieval Studies at the University of Notre Dame. Pre-eminent as a Thomas scholar, his many books include Aquinas Against the Averroists & A First Glance at St Thomas Aquinas.
There are readers of Aquinas's works, but Penguin's surpasses all by its sheer size, the very representative choice of texts, the excellent translations, and scholarly, informative introductions. Albert E. Gunn
