Hence, in regard to our subject, 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--such as
political or religious pamphlets, novels, poetry, and the like, which
make a noise and reach perhaps several editions in their first and last
years of existence. 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.

One can never read too little of bad, or too much of good books: bad
books are intellectual poison; they destroy the mind.

In order to read what is good one must make it a condition never to read
what is bad; for life is short, and both time and strength limited.

shallow, insipid gossip of some stupid head of to-day more homogeneous
and agreeable than the thoughts of great minds. I have to thank fate,
however, that a fine epigram of A.B. Schlegel, which has since been my
guiding star, came before my notice as a youth:
