Because you are trustworthy, you do not allow us to be tempted more fiercely than we can bear, but along with the temptation you ordain the outcome of it, so that we can endure. Let me, then, confess what I know about myself, and confess too what I do not know, because what I know of myself I know only because you shed light on me, and what I do not know I shall remain ignorant about until my darkness becomes like bright noon before your face.

– Saint Augustine, The Confessions X, 5, 7.
