Arthur Schopenhauer,
The Essays of Arthur Schopenhauer…
“ The thought we read is related to the thought which springs up in ourselves, as the fossil-impress of some prehistoric plant to a plant as it buds forth in spring-time. Reading is nothing more than a substitute for thought of one's own. It means putting the mind into leading-strings. The multitude of books serves only to show how many false paths there are, and how widely astray a man may wander if he follows any of them. But he who is guided by his genius, he who thinks for himself, who thinks spontaneously and exactly, possesses the only compass by which he can steer aright. ”
