The assumption that animals are without rights, and the illusion that our treatment of them has no moral significance, is a positively outrageous example of Western crudity and barbarity. Universal compassion is the only guarantee of morality.
We must set limits to our wishes, curb our desires, moderate our anger, always remembering that an individual can attain only an infinitesimal share in anything that is worth having; and that on the other hand, everyone must incur many of the ills of life
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.
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.
If children were brought into the world by an act of pure reason alone, would the human race continue to exist?

That the outer man is a picture of the inner, and the face an expression and revelation of the whole character, is a presumption likely enough in itself, and therefore a safe one to go on; borne out as it is by the fact that people are always anxious to see anyone who has made himself famous.
