If you want to overcome the whole world, overcome yourself.

Man grows used to everything, the scoundrel!

You know, my boy, he said, it's impossible to love men such as they are. And yet we must. So try to do good to men by doing violence to your feelings, holding your nose, and shutting your eyes, especially shutting your eyes. Endure their villainy without anger, as much as possible; try to remember that you're a man too. For, if you're even a little above average intelligence, you'll have the propensity to judge people severely. Men are vile by nature and they'd rather love out of fear. Don't give in to such love: despise it always.

One can't understand everything at once, we can't begin with perfection all at once! In order to reach perfection one must begin by being ignorant of a great deal. And if we understand things too quickly, perhaps we shan't understand them thoroughly.

Every decent man of our age must be a coward and a slave. That is his normal condition. Of that I am firmly persuaded. He is made and constructed to that very end. And not only at the present time owing to some casual circumstance, but always, at all times, a decent man is bound to be a coward and a slave.

One can tell a child everything, anything. I have often been struck by the fact that parents know their children so little. They should not conceal so much from them. How well even little children understand that their parents conceal things from them, because they consider them too young to understand! Children are capable of giving advice in the most important matters.

So long as man remains free he strives for nothing so incessantly and so painfully as to find someone to worship.
