Science ... has no consideration for ultimate purposes, any more than Nature has, but just as the latter occasionally achieves things of the greatest suitableness without intending to do so, so also true science, as the imitator of nature in ideas, will occasionally and in many ways further the usefulness and welfare of man,-but also without intending to do so.

Reason is the cause of our falsification of the evidence of the senses. In so far as the senses show becoming, passing away, change, they do not lie.

A degree of culture, and assuredly a very high one, is attained when man rises above superstitions and religious notions and fears, and, for instance, no longer believes in guardian angels or in original sin, and has also ceased to talk of the salvation of his soul.

Creating-that is the great salvation from suffering.

The condition that gives birth to a rule is not the same as the condition to which the rule gives birth.

Every word has its fragrance: there is a harmony and a disharmony of fragrances, and hence of words.

The best of all things is something entirely outside your grasp: not to be born, not to be, to be nothing. But the second-best thing for you - is to die soon.
