“He is not in the habit of explaining himself. He is not in the habit of discussing his successes. But whenever good fortune has called on him, he has been there, planted on the threshold, ready to fling open the door to her timid scratch on the wood.”

“What virtue is there in a man who demonstrates goodness because he has been bred to it? It is his habit from youth. But a man who has known unkindness and want, for him to be kind and charitable to those who have been the cause of his misfortunes, that is a virtuous man.”

“It is thus religion infatuates man from his infancy, fills him with vanity and fanaticism: if he has a heated imagination it drives him on to fury; if he has activity, it makes him a madman, who is frequently as cruel to himself, as he is dangerous and incommodious to others: if, on the contrary, he be phlegmatic or of a slothful habit, he becomes melancholy and is useless to society.”

“For several thousand years man has been in contact with animals whose character and habits have been deformed by domestication. He has ended by believing that he understands them. All he means by this is that he is able to rely on certain reflex actions which he himself has implanted in them. He will flatter himself at times on the grasp of animal psychology which has brought him the love of the dog and the purr of the cat; and on the strength of such assumptions he approaches the beasts of the jungle. The old tag about nature being an open book is just not true. What nature offers on a first examination may appear to be simple but it is never as simple as it appears.”

“He has a habit of runnng faster than he should and using his superior hearing when he should not.”

“As Aristotle said, 'Excellence is a habit.' I would say furthermore that excellence is made constant through the feeling that comes right after one has completed a work which he himself finds undeniably awe-inspiring. He only wants to relax until he's ready to renew such a feeling all over again because to him, all else has become absolutely trivial.”
