Psychology lures even most serious people into romancing, and quite unconsciously.

That's always the way with fanatics; they cross themselves at the tavern and throw stones at the temple.

I cannot understand why the world is arranged as it is.

At some thoughts one stands perplexed, especially at the sight of men's sin, and wonders whether one should use force or humble love. Always decide to use humble love. If you resolve on that once for all, you may subdue the whole world.

Above all, don't lie to yourself.

The man who lies to himself can be more easily offended than anyone else. You know it is sometimes very pleasant to take offense, isn't it? A man may know that nobody has insulted him, but that he has invented the insult for himself, has lied and exaggerated to make it picturesque, has caught at a word and made a mountain out of a molehill--he knows that himself, yet he will be the first to take offense, and will revel in his resentment till he feels great pleasure in it.

Intelligence alone is not nearly enough when it comes to acting wisely.
