The torch of doubt and chaos, this is what the sage steers by.

My opinion is that you never find happiness until you stop looking for it.

All men know the use of the useful, but nobody knows the use of the useless. Where can I find a man who has forgotten words so that I can have a word with him?

The birth of a man is the birth of his sorrow. The longer he lives, the more stupid he becomes, because his anxiety to avoid unavoidable death becomes more and more acute. What bitterness! He lives for what is always out of reach! His thirst for survival in the future makes him incapable of living in the present.

Great understanding is broad and unhurried; little understanding is cramped and busy

Study is to study what cannot be studied. Undertaking means undertaking what cannot be undertaken. Philosophizing is to philosophize about what cannot be philosophized about. Knowing that knowing is unknowable is true perfection.
