Nietzsche was stupid and abnormal.

If a man's aspirations towards a righteous life are serious.. .if he earnestly and sincerely seeks a righteous life, his first act of abstinence is from animal food, because, not to mention the excitement of the passions produced by such food, it is plainly immoral, as it requires an act contrary to moral feeling, i. e., killing - and is called forth only by greed.

Knowledge is real knowledge only when it is acquired by the efforts of your intellect, not by memory

What is reason given me for, if I am not to use it to avoid bringing unhappy beings into the world!

It may be suggested by some books that it is not a sin to kill an animal, but it is written in our own hearts - more clearly than in any book - that we should take pity on animals in the same way as we do on humans.

If people lacked the capacity to receive the thoughts of the men who preceded them and to pass on to others their own thoughts, men would be like wild beasts. And if men lacked this other capacity of being infected by art, people would be almost more savage still, and, above all, more separated from and more hostile to one another. Therefore the activity of art is a most important one, as important as the activity of speech itself and as generally diffused.

Art begins when a man, with a purpose of communicating to other people a feeling he once experienced, calls it up again within himself and expresses it by certain external signs.
