There are those, of course, who deny that they need any form of authority. They are the popular atheists and agnostics. Such men say that they must be shown by 'reason' whatever they are to accept as true. But the great thinkers among non-Christian men have taken no such position.

Cornelius Van TilIf 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
