"Nothing is better than conversation as a corrective of self-sufficiency. In educated conversation a person soon finds his own level. He learns more truly than from books, in converse with living people, he learns to estimate his powers modestly and justly. A book is passive; it does not repel pretensions; it does not rebuke vanity. Indeed, reading and study become to many but the nature of conceit. In conversation a person is not long discovering that he alone does not know everything, and that though he were to die, wisdom would not perish with him." Author unknown.
