“Father Brown got to his feet, putting his hands behind him. 'Odd, isn't it,' he said, 'that a thief and a vagabond should repent, when so many who are rich and secure remain hard and frivolous, and without fruit for God or man?”

“Yes, he said in a voice indescribable, you are right. I am afraid of him. Therefore I swear by God that I will seek out this man whom I fear until I find him, and strike him on the mouth. If heaven were his throne and the earth his footstool, I swear that I would pull him down. How? asked the staring Professor. Why? Because I am afraid of him, said Syme; and no man should leave in the universe anything of which he is afraid.”

“He is a man, I think," he said, "who cares for nothing but a joke. He is a dangerous man."Lambert laughed in the act of lifting some macaroni to his mouth."Dangerous!" he said. "You don't know little Quin, sir!""Every man is dangerous," said the old man, without moving, "Who cares only for one thing. I was once dangerous myself.”

“The word "good" has many meanings. For example, if a man were to shoot his grandmother at a range of five hundred yards, I should call him a good shot, but not necessarily a good man.”

“Some stupid people started the idea that because women obviously back up their own people through everything, therefore women are blind and do not see anything. They can hardly have known any women. The same women who are ready to defend their men through thick and thin are (in their personal intercourse with the man) almost morbidly lucid about the thinness of his excuses or the thickness of his head. A man's friend likes him but leaves him as he is: his wife loves him and is always trying to turn him into somebody else. Women who are utter mystics in their creed are utter cynics in their criticism. Thackeray expressed this well when he made Pendennis' mother, who worshipped her son as a god, yet assume that he would go wrong as a man. She underrated his virtue, though she overrated his value. The devotee is entirely free to criticise; the fanatic can safely be a sceptic. Love is not blind; that is the last thing that it is. Love is bound; and the more it is bound the less it is blind.”

“Sunday is a fixed star," he said."You shall see him a falling star," said Syme, and put on his hat.The decision of his gesture drew the Professor vaguely to his feet."Have you any idea," he asked, with a sort of benevolent bewilderment, "exactly where you are going?""Yes," replied Syme shortly, "I am going to prevent this bomb being thrown in Paris.""Have you any conception how?" inquired the other."No," said Syme with equal decision.”

“Is that all?" asked Flambeau after a long pause. "Have we got to the dull truth at last?""Oh, no," said Father Brown.As the wind died in the most distant pine woods with a long hoot as of mockery Father Brown, with an utterly impassive face, went on:"I only suggested that because you said one could not plausibly connect snuff with clockwork or candles with bright stones. Ten false philosophies will fit the universe; ten false theories will fit Glengyle Castle. But we want the real explanation of the castle and the universe. But are there no other exhibits?"Craven laughed, and Flambeau rose smiling to his feet and strolled down the long table. [Ch.6]”
