There is nothing in the world more difficult than candor, and nothing easier than flattery. If there is a hundredth of a fraction of a false note to candor, it immediately produces dissonance, and as a result, exposure. But in flattery, even if everything is false down to the last note, it is still pleasant, and people will listen not without pleasure; with coarse pleasure, perhaps, but pleasure nevertheless.
Fyodor DostoevskyEvery man has some reminiscences which he would not tell to everyone, but only to his friends. He has others which he would not reveal even to his friends, but only to himself, and that in secret. But finally there are still others which a man is even afraid to tell himself, and every decent man has a considerable number of such things stored away. That is, one can even say that the more decent he is, the greater the number of such things in his mind.
Fyodor DostoevskyWe must never forget that human motives are generally far more complicated than we are apt to suppose, and that we can very rarely accurately describe the motives of another.
