Dr. Billy Sichone concludes:

We can safely conclude that Theistic Epistemology is the way to go as taught by Cornelious Van Til, the presuppositionalist apologetics approach fore-runner, because we cannot truly know anything in the truest sense of the word unless we begin with God. Though Polanyi was on track towards the truth, he failed to point the finger ultimately where the truth originates-God. He instead pointed his thinking towards what he called “Tacit knowledge”. Perhaps that is the best light Polanyi had and should thus commend him somewhat because he differs from other epistemologists radically though he too does not match up to Van Til’s position where God is over all things and it is from/in Him that all things consist.
