This is my first foray into Thomas Aquinas. The author, Peter Kreeft, is a catholic devotee of Thomism, and this permeates the whole book, for better or worse. I found the lectures to get progressively more annoying as Kreeft dismissively put a match to all opposing straw views and delighted in Aquinas's simple common sense approach. Aquinas clearly suffered from a Middle Ages obsession with forms, essences, spirits, beings, natures, mind, soul, hierarchies, and a whole list of theoretical assumptions that must have seemed so common sensical to him, but have been seriously questioned by later thinkers (not to mention earlier thinkers) as to their relevance to epistemology and metaphysics. I'd like to see Thomas go head to head with a good reductionist. IMO, Thomas simply deduced his way to the nice conclusions that he wanted in the first place, which isn't so bad because he seemed like a pretty nice guy.
