"Careless about dress and demeanor and other worldly fripperies, St. Thomas is a man who enjoys banquets, conviviality, jokes and pranks. His inner certitude about religious truth permits him to accept the world and its freedom and it endows him with a childlike innocence" (L.J. Clipper).
The twentieth century's foremost authority on St. Thomas Aquinas, Etienne Gilson, has commented on this work, "I consider it as being without possible comparison the best book ever written on St. Thomas. Nothing short of a genius can account for such an achievement."
Many consider this to be Chesterton's best book.
