Happiness of any given life is to be measured, not by its joys and pleasures, but by the extent to which it has been free from suffering-from positive evil.

It is only a man's own fundamental thoughts that have truth and life in them.

Every time a man is begotten and born, the clock of human life is wound up anew to repeat once more its same old tune that has already been played innumerable times, movement by movement and measure by measure, with insignificant variations.

Although as a rule the absurd culminates, and it seems impossible for the voice of the individual ever to penetrate through the chorus of foolers and fooled, still there is left to the genuine works of all times a quite peculiar, silent, slow, and powerful influence; and as if by a miracle, we see them rise at last out of the turmoil like a balloon that floats up out of the thick atmosphere of this globe into purer regions. Having once arrived there, it remains at rest, and no one can any longer draw it down again.

Just as a stream flows smoothly on as long as it encounters no obstruction, so the nature of man and animal is such that we never really notice or become conscious of what is agreeable to our will; if we are to notice something, our will has to have been thwarted, has to have experienced a shock of some kind.

We will gradually become indifferent to what goes on in the minds of other people when we acquire a knowledge of the superficial nature of their thoughts, the narrowness of their views and of the number of their errors. Whoever attaches a lot of value to the opinions of others pays them too much honor.

Nothing shocks our moral feelings so deeply as cruelty does. We can forgive every other crime, but not cruelty. The reason for this is that it is the very opposite of compassion.
