Vanity is a desire of personal glory, the wish to be appreciated, honoured, and run after, not because of one's personal qualities, merits, and achievements, but because of one's individual existence. At best, therefore, it is a frivolous beauty whom it befits.

The most important matters of feeling as of reason, of experience as of reflection, should be treated of only by word of mouth. The spoken word at once dies if it is not kept alive by some other word following on it and suited to the hearer. Observe what happens in social converse. If the word is not dead when it reaches the hearer, he murders it at once by a contradiction, a stipulation, a condition, a digression, an interruption, and all the thousand tricks of conversation. With the written word the case is still worse. No one cares to read anything to which he is not already to some extent accustomed: he demands the known and the familiar under an altered form. Still the written word has this advantage, that it lasts and can await the time when it is allowed to take effect.

378

Both what is reasonable and what is unreasonable have to undergo the like contradiction.

379

Dialectic is the culture of the spirit of contradiction, which is given to man that he may learn to perceive the differences between things.

380

With those who are really of like disposition with himself a man cannot long be at variance; he will always come to an agreement again. With those who are really of adverse disposition, he may in vain try to preserve harmony; he will always come to a separation again.

381

Opponents fancy they refute us when they repeat their own opinion and pay no attention to ours.

382

People who contradict and dispute should now and then remember that not every mode of speech is intelligible to every one.

383

Every man hears only what he understands.

384

I am quite prepared to find that many a reader will disagree with me; but when he has a thing before him in black and white, he must let it stand. Another reader may perhaps take up the very same copy and agree with me.

385

The truest liberality is appreciation.

386

For the strenuous man the difficulty is to recognise the merits of elder contemporaries and not let himself be hindered by their defects.

387

Some men think about the defects of their friends, and there is nothing to be gained by it. I have always paid attention to the merits of my enemies, and found it an advantage.

388

There are many men who fancy they understand whatever they experience.

389

The public must be treated like women: they must be told absolutely nothing but what they like to hear.

390

Every age of man has a certain philosophy answering to it. The child comes out as a realist: he finds himself as convinced that pears and apples exist as that he himself exists. The youth in a storm of inner pa.s.sion is forced to turn his gaze within, and feel in advance what he is going to be: he is changed into an idealist. But the man has every reason to become a sceptic: he does well to doubt whether the means he has chosen to his end are the right ones. Before and during action he has every reason for keeping his understanding mobile, that he may not afterwards have to grieve over a false choice. Yet when he grows old he will always confess himself a mystic: he sees that so much seems to depend on chance; that folly succeeds and wisdom fails; that good and evil fortune are brought unexpectedly to the same level; so it is and so it has been, and old age acquiesces in that which is and was and will be.

391

When a man grows old he must consciously remain at a certain stage.

392

It does not become an old man to run after the fashion, either in thought or in dress. But he must know where he is, and what the others are aiming at.

What is called fashion is the tradition of the moment. All tradition carries with it a certain necessity for people to put themselves on a level with it.

393

We have long been busy with the critique of reason. I should like to see a critique of common-sense. It would be a real benefit to mankind if we could convincingly prove to the ordinary intelligence how far it can go; and that is just as much as it fully requires for life on this earth.

394

The thinker makes a great mistake when he asks after cause and effect: they both together make up the indivisible phenomenon.

395

All practical men try to bring the world under their hands; all thinkers, under their heads. How far each succeeds, they may both see for themselves.

396

Shall we say that a man thinks only when he cannot think out that of which he is thinking?

397

What is invention or discovery? It is the conclusion of what we were looking for.

398

It is with history as with nature and with everything of any depth, it may be past, present, or future: the further we seriously pursue it, the more difficult are the problems that appear. The man who is not afraid of them, but attacks them bravely, has a feeling of higher culture and greater ease the further he progresses.

399

Every phenomenon is within our reach if we treat it as an inclined plane, which is of easy ascent, though the thick end of the wedge may be steep and inaccessible.

If a man would enter upon some course of knowledge, he must either be deceived or deceive himself, unless external necessity irresistibly determines him. Who would become a physician if, at one and the same time, he saw before him all the horrible sights that await him?
