The art of not reading is highly important. This consists in not taking a book into one’s hand merely because it is interesting the great public at the time. […] Remember rather that the man who writes for fools always finds a large public: and only read for a limited and definite time exclusively the works of great minds, those who surpass other men of all times and countries, and whom the voice of fame points to as such. These alone really educate and instruct.
Arthur Schopenhauer, On Reading and Books
