A rare example of honesty, from The Trinity: Evidence and Issues
the non-Christian begins with his own set of presuppositions. He assumes that his first principles are a priori truths. Even the idea that induction is neutral is an a priori concept.
Just as the Christian philosopher begins with the assumption that God is the measure of all things, the humanistic philosopher begins with the assumption that man is the measure of all things.
To the Christian philosopher, the existence of man is justified by the prior existence of God, while to the humanist philosopher, the existence of God is justified by the priori existence of man
What a rare piece of truth.
