Nihilism: any aim is lacking, any answer to the question "why" is lacking. What does nihilism mean?--that the supreme values devaluate themselves.

So far there has been no philosopher in whose hands philosophy has not grown into an apology for knowledge; on this point, at least, every one is an optimist, that the greatest usefulness must be ascribed to knowledge. They are all tyrannized over by logic, and this is optimism in its essence.

O sancta simplicitas! What strange simplification and falsification mankind lives on! One can never cease to marvel once one has acquired eyes for this marvel!
