Every word instantly becomes a concept precisely insofar as it is not supposed to serve as a reminder of the unique and entirely individual original experience to which it owes its origin; but rather, a word becomes a concept insofar as it simultaneously has to fit countless more or less similar cases -- which means, purely and simply, cases which are never equal and thus altogether unequal.
Friedrich NietzscheSo 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.
Friedrich NietzscheNo more fiction, for now we calculate; but that we may calculate, we had to make fiction first.
