If one does not make human knowledge wholly dependent upon the original self-knowledge and consequent revelation of God to man, then man will have to seek knowledge within himself as the final reference point. Then he will have to seek an exhaustive understanding of reality. He will have to hold that if he cannot attain to such an exhaustive understanding of reality he has no true knowledge of anything at all. Either man must then know everything or he knows nothing. This is the dilemma that confronts every form of non-Christian epistemology
“I would not talk endlessly about facts and more facts without ever challenging the non-believer’s philosophy of fact.” — Cornelius Van Til
