For a man to know God, and to know himself and his proper rank — a knowledge now possessed even by Christians who are thought to be quite unlearned — is a knowledge superior to natural science and astronomy and to all philosophy concerning such matters.

Moreover, for our intellect to know its own infirmity, and to seek healing for it, is incomparably greater than to know and search out the magnitude of the stars… and, in short, all of the multiform relationships which arise from the many different motions in the heavens. For the intellect that recognizes its own infirmity has discovered where to enter in order to find salvation and how to approach the light of knowledge and receive the true wisdom that does not pass away with this present world.

– St. Gregory Palamas, Philokalia, Vol. 4
