Men of learning are those who have read the contents of books. Thinkers, geniuses, and those who have enlightened the world and furthered the race of men, are those who have made direct use
of the book of the world.
If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence, or at any rate not take it upon himself to impose that burden upon it in cold blood?
The auspices for philosophy are bad if, when proceeding ostensibly on the investigation of truth, we start saying farewell to all uprightness, honesty and sincerity, and are intent only on passing ourselves off for what we are not. We then assume, like those three sophists [Fichte, Schelling and Hegel], first a false pathos, then an affected and lofty earnestness, then an air of infinite superiority, in order to impose where we despair of ever being able to convince.
Virtue is as little to be acquired by learning as genius; nay, the idea is barren, and is only to be employed as an instrument, in the same way as genius in respect to art. It would be as foolish to expect that our moral and ethical systems would turn out virtuous, noble, and holy beings, as that our aesthetic systems would produce poets, painters, and musicians.
For it is a matter of daily observation that people take the greatest pleasure in that which satisfies their vanity; and vanity cannot be satisfied without comparison with others.
It is only the man whose intellect is clouded by his sexual impulse that could give the name of the fair sex to that undersized, narrow-shouldered, broad-hipped, and short-legged race.
It is only a man's own fundamental thoughts that have truth and life in them. For it is these that he really and completely understands. To read the thoughts of others is like taking the remains of someone else's meal, like putting on the discarded clothes of a stranger.
Just as the witticism brings two very different real objects under one concept, the pun brings two different concepts, by the assistance of accident, under one word.
The inexpressible depth of music, so easy to understand and yet so inexplicable, is due to the fact that it reproduces all the emotions of our innermost being, but entirely without reality and remote from its pain… Music expresses only the quintessence of life and its events, never these themselves.
