Who this is

“While all of Germany decided that reality was made of mind, a silenced priest in a Bohemian farmhouse quietly built the mind-independent logic that the modern world — from set theory to computer science — actually runs on.”
— The Great Philosophers, Ch. 166

The big idea, in the book's words:

“Truths exist in themselves. A proposition is true or false whether or not any mind ever thinks it — and logic is the science of these mind-independent truths, not of how humans happen to reason.”
— The Great Philosophers, Ch. 166
