If children were brought into the world by an act of pure reason alone, would the human race continue to exist? Would not a man rather have so much sympathy with the coming generation as to spare it the burden of existence, or at any rate not take it upon himself to impose that burden upon it in cold blood?
The little incidents and accidents of every day fill us with emotion, anxiety, annoyance, passion, as long as they are close to us, when they appear so big, so important, so serious; but as soon as they are borne down the restless stream of time they lose what significance they had; we think no more of them and soon forget them altogether. They were big only because they were near.
If anyone spends almost the whole day in reading...he gradually loses the capacity for thinking...This is the case with many learned persons; they have read themselves stupid
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.

If, while hurrying ostensibly to the temple of truth, we hand the reins over to our personal interests which look aside at very different guiding stars, for instance at the tastes and foibles of our contemporaries, at the established religion, but in particular at the hints and suggestions of those at the head of affairs, then how shall we ever reach the high, precipitous, bare rock whereon stands the temple of truth?
Sleep is the interest we have to pay on the capital which is called in at death; and the higher the rate of interest and the more regularly it is paid, the further the date of redemption is postponed.
If a man sets out to hate all the miserable creatures he meets, he will not have much energy left for anything else; whereas he can despise them, one and all, with the greatest ease.
