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.
Man is the cruelest animal. At tragedies, bullfights, and crucifixions he has so far felt best on earth; and when he invented hell for himself, behold, that was his very heaven.
All roads are blocked to a philosophy which reduces everything to the word "no." To "no" there is only one answer and that is "yes." Nihilism has no substance. There is no such thing as nothingness, and zero does not exist. Everything is something. Nothing is nothing. Man lives more by affirmation than by bread.
The poor and the low have their way of expressing the last facts of philosophy as well as you. "Blessed be nothing," and "The worse things are, the better they are," are proverbs which express the transcendentalism of common life.
A philosophy can and must be worked out with the greatest rigour and discipline in the details, but can ultimately be founded on nothing but faith: and this is the reason, I suspect, why the novelties in philosophy are only in elaboration, and never in fundamentals.
