Religion is the metaphysics of the masses.

This is the case with many learned persons; they have read themselves stupid.

It is, indeed, only in old age that intellectual men attain their sublime expression, whilst portraits of them in their youth show only the first traces of it.

Thus, the task is not so much to see what no one yet has seen, but to think what nobody yet has thought about that which everybody sees.

Pleasure is never as pleasant as we expected it to be and pain is always more painful. The pain in the world always outweighs the pleasure. If you don't believe it, compare the respective feelings of two animals, one of which is eating the other.

The greatest wisdom is to make the enjoyment of the present the supreme object of life; because that is the only reality, all else being merely the play of thought. On the other hand, such a course might just as well be called the greatest folly: for that which in the next moment exists no more, and vanishes utterly, like a dream, can never be worth a serious effort.

If the lives of men were relieved of all need, hardship and adversity; if everything they took in hand were successful, they would be so swollen with arrogance that, though they might not burst, they would present the spectacle of unbridled folly-nay, they would go mad. And I may say, further, that a certain amount of care or pain or trouble is necessary for every man at all times. A ship without ballast is unstable and will not go straight.
