To buy books would be a good thing if we could also buy the time to read them; but the purchase of books is often mistaken for the assimilation and mastering of their contents.
A man never is happy, but spends his whole life in striving after something which he thinks will make him so; he seldom attains his goal, and when he does, it is only to be disappointed; he is mostly shipwrecked in the end, and comes into harbor with mast and rigging gone. And then, it is all one whether he has been happy or miserable; for his life was never anything more than a present moment always vanishing; and now it is over.
As the biggest library if it is in disorder is not as useful as a small but well-arranged one, so you may accumulate a vast amount of knowledge but it will be of far less value than a much smaller amount if you have not thought it over for yourself.
No one knows what capacities for doing and suffering he has in himself, until something comes to rouse them to activity: just as in a pond of still water, lying there like a mirror, there is no sign of the roar and thunder with which it can leap from the precipice, and yet remain what it is; or again, rise high in the air as a fountain. When water is as cold as ice, you can have no idea of the latent warmth contained in it.
Optimism is not only a false but also a pernicious doctrine, for it presents life as a desirable state and man's happiness as its aim and object. Starting from this, everyone then believes he has the most legitimate claim to happiness and enjoyment. If, as usually happens, these do not fall to his lot, he believes that he suffers an injustice, in fact that he misses the whole point of his existence.
It is only a man's own fundamental thoughts that have truth and life in them. For it is these that he really and completely understands. To read the thoughts of others is like taking the remains of someone else's meal, like putting on the discarded clothes of a stranger.
Truth that is naked is the most beautiful, and the simpler its expression the deeper is the impression it makes; this is partly because it gets unobstructed hold of the hearer’s mind without his being distracted by secondary thoughts, and partly because he feels that here he is not being corrupted or deceived by the arts of rhetoric, but that the whole effect is got from the thing itself.
