Mostly it is loss which teaches us about the worth of things.
Life is a constant process of dying.
Human life must be some form of mistake.
Our life is a loan received from death with sleep as the daily interest on this loan.
This is the case with many learned persons; they have read themselves stupid.
The conviction that the world and man is something that had better not have been, is of a kind to fill us with indulgence towards one another.
That I could clamber to the frozen moon. And draw the ladder after me.
I am often surprised by the cleverness, and now and again by the stupidity, of my dog; and I have similar experiences with mankind.
We forfeit three-quarters of ourselves in order to be like other people.
So the problem is not so much to see what nobody has yet seen, as to think what nobody has yet thought concerning that which everybody sees.
If the world were a paradise of luxury and ease, a land flowing with milk and honey, where every Jack obtained his Jill at once and without any difficulty, men would either die of boredom or hang themselves; or there would be wars, massacres, and murders; so that in the end mankind would inflict more suffering on itself than it has now to accept at the hands of Nature.
There is only one inborn error, and that is the notion that we exist in order to be happy... So long as we persist in this inborn error... the world seems to us full of contradictions. For at every step, in things great and small, we are bound to experience that the world and life are certainly not arranged for the purpose of maintaining a happy existence... hence the countenances of almost all elderly persons wear the expression of what is called disappointment.
Genius is the ability to leave entirely out of sight our own interest, our willing, and our aims, and consequently to discard entirely our own personality for a time, in order to remain pure knowing subject, the clear eye of the world; and this not merely for moments, but with the necessary continuity and conscious thought to enable us to repeat by deliberate art what has been apprehended and “what in wavering apparition gleams fix in its place with thoughts that stand for ever!
A man is never happy, but spends his whole life in striving after something that 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 harbour with mast and rigging gone. And then, it is all one whether he is happy or miserable; for his life was never anything more than a present moment always vanishing; and now it is over.
The life of an individual is a constant struggle, and not merely a metaphorical one against want or boredom, but also an actual struggle against other people. He discovers adversaries everywhere, lives in continual conflict and dies with sword in hand.
If the immediate and direct purpose of our life is not suffering then our existence is the most ill-adapted to its purpose in the world.
All striving comes from lack, from a dissatisfaction with one’s condition, and is thus suffering as long as it is not satisfied; but no satisfaction is lasting; instead, it is only the beginning of a new striving. We see striving everywhere inhibited in many ways, struggling everywhere; and thus always suffering; there is no final goal of striving, and therefore no bounds or end to suffering.
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 to you than a much smaller amount if you have not thought it over for yourself; because only through ordering what you know by comparing every truth with every other truth can you take complete possession of your knowledge and get it into your power.
Sociability belongs to the most dangerous, even destructive inclinations, since it brings us into contact with beings the great majority of whom are morally bad and intellectually dull or perverted.
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.
