Idolatry is committed, not merely by setting up false gods, but also by setting up false devils; by making men afraid of war or alcohol, or economic law, when they should be afraid of spiritual corruption and cowardice.

The materialist theory of history, that all politics and ethics are the expression of economics, is a very simple fallacy indeed. It consists simply of confusing the necessary conditions of life with the normal preoccupations of life, that are quite a different thing.

Very few people in the world would care to listen to the real defense of their own characters. The real defense, the defense which belongs to the Day of Judgment, would make such damaging admissions, would clear away so many artificial virtues, would tell such tragedies of weakness and failure, that a man would sooner be misunderstood and censured by the world than exposed to that awful and merciless eulogy.

Progress is Providence without God. That is, it is a theory that everything has always perpetually gone right by accident. It is a sort of atheistic optimism, based on an everlasting coincidence far more miraculous than a miracle.

The modern world is not evil; in some ways the modern world is far too good. It is full of wild and wasted virtues. When a religious scheme is shattered (as Christianity was shattered at the Reformation), it is not merely the vices that are let loose. The vices are, indeed, let loose, and they wander and do damage. But the virtues are let loose also; and the virtues wander more wildly, and the virtues do more terrible damage. The modern world is full of the old Christian virtues gone mad. The virtues have gone mad because they have been isolated from each other and are wandering alone.

Only friendliness produces friendship. And we must look far deeper into the soul of man for the thing that produces friendliness.

Life is serious all the time, but living cannot be. You may have all the solemnity you wish in your neckties, but in anything important (such as sex, death, and religion), you must have mirth or you will have madness.
