“A poet or philosopher should have no fault to find with his age if it only permits him to do his work undisturbed in his own corner; nor with his fate if the corner granted him allows of his following his vocation without having to think about other people.”

“The cheapest sort of pride is national pride; for if a man is proud of his own nation, it argues that he has no qualities of his own of which he can be proud; otherwise he would not have recourse to those which he shares with so many millions of his fellowmen. The man who is endowed with important personal qualities will be only too ready to see clearly in what respects his own nation falls short, since their failings will be constantly before his eyes. But every miserable fool who has nothing at all of which he can be proud adopts, as a last resource, pride in the nation to which he belongs; he is ready and glad to defend all its faults and follies tooth and nail, thus reimbursing himself for his own inferiority.”

“I have long held the opinion that the amount of noise that anyone can bear undisturbed stands in inverse proportion to his mental capacity and therefore be regarded as a pretty fair measure of it.”

“There is one thing that, more than any other, throws people absolutely off their balance — the thought that you are dependent upon them. This is sure to produce an insolent and domineering manner towards you. There are some people, indeed, who become rude if you enter into any kind of relation with them; for instance, if you have occasion to converse with them frequently upon confidential matters, they soon come to fancy that they can take liberties with you, and so they try and transgress the laws of politeness. This is why there are so few with whom you care to become more intimate, and why you should avoid familiarity with vulgar people. If a man comes to think that I am more dependent upon him than he is upon me, he at once feels as though I had stolen something from him; and his endeavor will be to have his vengeance and get it back. The only way to attain superiority in dealing with men, is to let it be seen that you are independent of them.”

“To free a man from error is not to deprive him of anything but to give him something: for the knowledge that a thing is false is a piece of truth. No error is harmless: sooner or later it will bring misfortune to him who harbours it. Therefore deceive no one, but rather confess ignorance of what you do not know, and leave each man to devise his own articles of faith for himself.”

“Everyone takes the limits of his own vision for the limits of the world.”

“A constant flow of thoughts expressed by other people can stop and deaden your own thought and your own initiative…. That is why constant learning softens your brain…. Stopping the creation of your own thoughts to give room for the thoughts from other books reminds me of Shakespeare’s remark about his contemporaries who sold their land in order to see other countries.”
