Our moral virtues benefit mainly other people; intellectual virtues, on the other hand, benefit primarily ourselves; therefore the former make us universally popular, the latter unpopular.
As the strata of the earth preserve in succession the living creatures of past epochs, so the shelves of libraries preserve in succession the errors of the past and their expositions, which like the former were very lively and made a great commotion in their own age but now stand petrified and stiff in a place where only the literary palaeontologist regards them.
There is more to be learnt from every page of David Hume than from the collected philosophical works of Hegel, Herbart, and Schleiermacher are taken together.
Every hero is a Samson. The strong man succumbs to the intrigues of the weak and the many; and if in the end he loses all patience he crushes both them and himself.
If two men who were friends in their youth meet again when they are old, after being separated for a life-time, the chief feeling they will have at the sight of each other will be one of complete disappointment at life as a whole; because their thoughts will be carried back to that earlier time when life seemed so fair as it lay spread out before them in the rosy light of dawn, promised so much — and then performed so little.
It often happens that we blurt out things that may in some kind of way be harmful to us, but we are silent about things that may make us look ridiculous; because in this case effect follows very quickly on cause.
Authors may be divided into falling stars, planets, and fixed stars: the first have a momentary effect; the second have a much longer duration; but the third are unchangeable, possess their own light, and work for all time.
A man who has no mental needs, because his intellect is of the narrow and normal amount, is, in the strict sense of the word, what is called a philistine.
Consider the Koran... this wretched book was sufficient to start a world-religion, to satisfy the metaphysical need of countless millions for twelve hundred years, to become the basis of their morality and of a remarkable contempt for death, and also to inspire them to bloody wars and the most extensive conquests. In this book we find the saddest and poorest form of theism. Much may be lost in translation, but I have not been able to discover in it one single idea of value.
That the outer man is a picture of the inner, and the face an expression and revelation of the whole character, is a presumption likely enough in itself, and therefore a safe one to go on; borne out as it is by the fact that people are always anxious to see anyone who has made himself famous. Photography offers the most complete satisfaction of our curiosity.
And yet, just as our body would burst asunder if the pressure of the atmosphere were removed from it, so would the arrogance of men expand, if not to the point of bursting then to that of the most unbridled folly, indeed madness, if the pressure of want, toil, calamity and frustration were removed from their life. One can even say that we require at all times a certain quantity of care or sorrow or want, as a ship requires ballast, in order to keep on a straight course.
Every woman while she would be ready to die of shame if surprised in the act of generation, nonetheless carries her pregnancy without a trace of shame and indeed with a kind of pride. The reason is that pregnancy is in a certain sense a cancellation of the guilt incurred by coitus; thus coitus bears all the shame and disgrace of the affair, while pregnancy, which is so intimately associated with it, stays pure and innocent and is indeed to some extent sacred.
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.
