What we call truths are just those errors that we cannot give up.

There is nothing more necessary than truth, and in comparison with it everything else has only secondary value. This absolute will to truth: what is it? Is it the will to not allow ourselves to be deceived? Is it the will not to deceive? One does not want to be deceived, under the supposition that it is injurious, dangerous, or fatal to be deceived.

Against war it may be said that it makes the victor stupid and the vanquished revengeful.

If you have an enemy, do not requite him evil with good, for that would put him to shame. Rather prove that he did you some good.

There is nothing that has caused me to meditate more on Plato's secrecy and sphinx-like nature, than the happily preserved petit fait that under the pillow of his death-bed there was found no 'Bible,' nor anything Egyptian, Pythagorean, or Platonic - but a book of Aristophanes. How could even Plato have endured life - a Greek life which he repudiated - without an Aristophanes!

I love him whose soul is deep even in the wounding, and may succumb through a small matter: thus goeth he willingly over the bridge.
