Philosophical studies are beset by one peril, a person easily brings himself to think that he thinks; and a smattering of science encourages conceit. He is above his companions. A hieroglyphic is a spell. The gnostic dogma is cuneiform writing to the million. Moreover, the vain man is generally a doubter. It is Newton who sees himself in a child on the sea shore, and his discoveries in the colored shells.
