-- from Paradoxes of Faith
We do not know what man is, or rather, we forget. The farther we go in studying him, the greater our loss of knowledge of him. We study him like an animal or like a machine. We see in him merely an object, odder than all the others. We are bewitched by physiology, psychology, sociology, and all their appendages.
Are we wrong, then, to pursue these branches of learning? Certainly not. Are the results bogus, then, or negligible? No. The fault lies not with them, but with ourselves, who know neither how to assign them their place nor how to judge them. We believe, without thinking, that the 'scientific' study of man can, at least by right, be universal and exhaustive. So it has the same deceptive - and deadly - result as the mania of introspection or the search for a static sincerity. The farther it goes, the more fearful it becomes. It eats into man, disintegrates and destroys him.
