Skepticism and dogmatism about revelation are correlate. And the way in which Christianity emphasized revelation in the earlier period and almost up to the Renaissance, is based on the tremendous shock Western mankind experienced when all the attempts of the Greek philosophers to bring certainty proved to be in vain. And this proof was given by the skeptical philosophers, which permeated all schools at that time.

Secondly, this skepticism gave rise to something else, namely to the new doctrine of knowledge, to the new epistemology, which Augustine created and which starts with the inner man instead of the experience of the external world. The skepticism, which was the end of all attempts to build a world in the objective realm, in the realm of things and objects, had the consequence that Augustine was thrown into himself to find the place of truth there, instead of outside. So we have two consequences of his participation in skepticism: the one is that he accepted revelation, and the other that insofar as he tried to find certainty as a philosopher, he tried to find it in the innermost center of his soul – in the subject himself.
