“This is a course I gave at home to my own high-school age youngsters as an uncomplicated introduction to Thomistic philosophy. It is meant to be an ‘easy listening’ intro that is not demanding; simply an introduction to the concepts, the structure, the principles of Thomistic philosophy.
And it is fun, as are all ventures of great truth. Originally designed for home-school high-schoolers, it soon became enthusiastically sought by adults. Aquinas Alive is now one of the most popular CD sets I’ve released.” – John Vennari
