I guess that this is my whole point. The book is entitled:
How the Church Built Western Civilization
But the poster changed the title by adding - Catholic -
I don't think that there had to be a Pope, or Saints, or other precepts of today's Catholism to advance western civilization. Just the opposite, as many independent thinkers decided to break away from these religious trappings starting in the 1500's.
Certainly these thinkers have added as much wisdom to modern man, although they're not Catholic. Also, certainly Judiasm was instrumental in the early years, and their influence has growth over the centuries.
Maybe we're talking semantics, like what the meaning of is - is, but I reject the notion that it was the trappings of Catholicism that fostered knowledge, and that if other Christian idealogy had been in place during that period that the growth of knowledge would have suffered.
