“It has gradually become clear to me what every great philosophy up till now has consisted of – namely, the confession of its originator, and a species of involuntary and unconscious autobiography; and moreover that the moral (or immoral) purpose in every philosophy has constituted the true vital germ out of which the entire plant has always grown.”

“That philosophy died yesterday, since Hegel or Marx, Nietzsche, or Heidegger—and philosophy should still wander toward the meaning of its death—or that it has always lived knowing itself to be dying... that philosophy died one day, within history, or that it has always fed on its own agony, on the violent way it opens history by opposing itself to nonphilosophy, which is its past and its concern, its death and wellspring; that beyond the death, or dying nature, of philosophy, perhaps even because of it, thought still has a future, or even, as is said today, is still entirely to come because of what philosophy has held in store; or, more strangely still, that the future itself has a future—all these are unanswerable questions. By right of birth, and for one time at least, these are problems put to philosophy as problems philosophy cannot resolve.”

“Noone has yet succeeded in inventing a philosophy at once credible and self-consistent. Locke aimed at credibility, and achieved it at the expense of consistency. Most of the great philosophers have done the opposite. A philosophy which is not self-consistent cannot be wholly true, but a philosophy which is self-consistent can very well be wholly false. The most fruitful philosophies have contained glaring inconsistencies, but for that very reason have been partially true. There is no reason to suppose that a self-consistent system contains more truth than one which, like Locke’s, is more or less wrong.”

“Every one of us, unconsciously, works out a personal philosophy of life, by which we are guided, inspired, and corrected, as time goes on. It is this philosophy by which we measure out our days, and by which we advertise to all about us the man, or woman, that we are... It takes but a brief time to scent the life philosophy of anyone. It is defined in the conversation, in the look of the eye, and in the general mien of the person. It has no hiding place. It's like the perfume of a flower -- unseen, but known almost instantly. It is the possession of the successful, and the happy. And it can be greatly embellished by the absorption of ideas and experiences of the useful of this earth.”

“One more word about giving instruction as to what the world ought to be. Philosophy in any case always comes on the scene too late to give it. As the thought of the world, it appears only when actuality is already there cut and dried after its process of formation has been completed... When philosophy paints its grey in grey, then has a shape of life grown old. By philosophy's grey in grey it cannot be rejuvenated but only understood. The owl of Minerva spreads its wings only with the falling of the dusk.”

“A history of civilization shares the presumptuousness of every philosophical enterprise: it offers the ridiculous spectacle of a fragment expounding the whole. Like philosophy, such a venture has no rational excuse, and is at best but a brave stupidity; but let us hope that, like philosophy, it will always lure some rash spirits into its fatal depths.”
