"I told Mr. Shaw (in substance) that he was a charming and clever fellow, but a common Calvinist. He admitted that this was true, and there (so far as I am concerned) is an end of the matter. He said that, of course, Calvin was quite right in holding that “if once a man is born it is too late to damn or save him.” That is the fundamental and subterranean secret; that is the last lie in hell.
The difference between Puritanism and Catholicism is not about whether some priestly word or gesture is significant and sacred. It is about whether any word or gesture is significant and sacred. To the Catholic every other daily act is dramatic dedication to the service of good or of evil. To the Calvinist no act can have that sort of solemnity, because the person doing it has been dedicated from eternity, and is merely filling up his time until the crack of doom. The difference is something subtler than plum-puddings or private theatricals; the difference is that to a Christian of my kind this short earthly life is intensely thrilling and precious; to a Calvinist like Mr. Shaw it is confessedly automatic and uninteresting. To me these threescore years and ten are the battle. To the Fabian Calvinist (by his own confession) they are only a long procession of the victors in laurels and the vanquished in chains. To me earthly life is the drama; to him it is the epilogue. Shavians think about the embryo; Spiritualists about the ghost; Christians about the man. It is as well to have these things clear.
…..though Mr. Shaw and his friends admit it is a superstition that a man is judged after death, they stick to their central doctrine, that he is judged before he is born.
Man is a misshapen monster, with his feet set forward and his face turned back. He can make the future luxuriant and gigantic, so long as he is thinking about the past. When he tries to think about the future itself, his mind diminishes to a pin point with imbecility, which some call Nirvana. To-morrow is the Gorgon; a man must only see it mirrored in the shining shield of yesterday. If he sees it directly he is turned to stone. This has been the fate of all those who have really seen fate and futurity as clear and inevitable. The Calvinists, with their perfect creed of predestination, were turned to stone. The modern sociological scientists (with their excruciating Eugenics) are turned to stone. The only difference is that the Puritans make dignified, and the Eugenists somewhat amusing, statues."

“Imagination does not breed insanity. Exactly what does breed insanity is reason. Poets do not go mad; but chess players do... Perhaps the strongest case of all is this: that only one great English poet went mad, Cowper. And he was definitely driven mad by logic, by the ugly and alien logic of predestination. Poetry was not the disease, but the medicine... He was damned by John Calvin... Poetry is sane because it floats easily in an infinite sea; reason seeks to cross the infinite sea, and so make it finite. The result is mental exhaustion... The poet only asks to get his head into the heavens. It is the logician who seeks to get the heavens into his head. And it is his head that splits... The madman is not the man who has lost his reason. The madman is the man who has lost everything except his reason... Materialists and madmen never have doubts... Mysticism keeps men sane. As long as you have the mystery you have health; when you destroy mystery you create morbidity.” ("Orthodoxy")
"A miracle only means the liberty of God. You may conscientiously deny either of them, but you cannot call your denial a triumph of the liberal idea. The Catholic Church believed that man and God both had a sort of spiritual freedom. Calvinism took away the freedom from man, but left it to God. Scientific materialism binds the Creator Himself; it chains up God as the Apocalypse chained the devil. It leaves nothing free in the universe. And those who assist this process are called the 'liberal theologians.'” (Orthodoxy")
