“Lesson Number One in controlling a man: find his weakness. Every man had one.”

“The wise man understands his weakness and seeks to find a lesson from it. The fool lets it control and destroy him.”

“We all are weak, in one way or another. It does not matter the species. Some times that weakness is a strength in dusguise. Sometimes it is our utter undoing. Some times it is both. A wise man seeks to find a lesson from it. A fool lets it control and destroy him.And sometimes the wise man is the fool.”

“[The shock of finding a familiar word in an unfamiliar setting.] A SS man would examine us. Whenever he found a weak one, a musulman as we called them, he would write his number down: good for the crematory.”

“Every man finds his limitations, Mr. Holmes, but at least it cures us of the weakness of self-satisfaction.”

“Every 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.”
