“The obvious effect of frivolous divorce will be frivolous marriage. If people can be separated for no reason they will feel it all the easier to be united for no reason.”

“Reason is always reasonable, even in the last limbo, in the lost borderland of all things. I know that people charge the Church with lowering reason, but it is really the other way. Alone on earth, the Church makes reason really supreme. Alone on earth, the Church affirms that God Himself is bound by reason.”

“All roads lead to Rome; which is one reason why many people never get there.”

“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?”

“The substance of all such paganism may be summarised thus. It is an attempt to reach the divine reality through the imagination alone; in its own field reason does not restrain it at all. It is vital to the view of all history that reason is something separate from religion even in the most rational of these civilisations. It is only as an afterthought, when such cults are decadent or on the defensive, that a few Neo-Platonists or a few Brahmins are found trying to rationalise them, and even then only by trying to allegorise them. But in reality the rivers of mythology and philosophy run parallel and do not mingle till they meet in the sea of Christendom.”

“Realism is simply Romanticism that has lost its reason...that is its reason for existing.”

“A fairly clear line separated advertisement from art. The First Effect I should say the first effect of the triumph of the capitalist (if we allow him to triumph) will be that that line of demarcation will entirely disappear.”
