Thackeray expressed this well when he made Pendennis mother, who worsh — Orthodoxy (book)

"The only possible excuse for this book is that it is an answer to a challenge. Even a bad shot is dignified when he accepts a duel. When some time ago I published a series of hasty but sincere papers, under the name of "Heretics," several critics for whose intellect I have a warm respect (I may mention specially Mr. G.S. Street) said that it was all very well for me to tell everybody to affirm his cosmic theory, but that I had carefully avoided supporting my precepts with example. "I will begin to worry about my philosophy," said Mr. Street, "when Mr. Chesterton has given us his." It was perhaps an incautious suggestion to make to a person only too ready to write books upon the feeblest provocation. But after all, though Mr. Street has inspired and created this book, he need not read it. If he does read it, he will find that in its pages I have attempted in a vague and personal way, in a set of mental pictures rather than in a series of deductions, to state the philosophy in which I have come to believe. I will not call it my philosophy; for I did not make it. God and humanity made it; and it made me."

"The strongest saints and the strongest sceptics alike took positive evil as the starting-point of their argument. If it be true (as it certainly is) that a man can feel exquisite happiness in skinning a cat, then the religious philosopher can only draw one of two deductions. He must either deny the existence of God, as all atheists do; or he must deny the present union between God and man, as all Christians do. The new theologians seem to think it a highly rationalistic solution to deny the cat."

"If you consulted your business experience instead of your ugly individualistic philosophy, you would know that believing in himself is one of the commonest signs of a rotter. Actors who cant act believe in themselves; and debtors who wont pay. It would be much truer to say that a man will certainly fail because he believes in himself. Complete self-confidence is not merely a sin; complete self-confidence is a weakness."

"For if this book is a joke it is a joke against me. I am the man who with the utmost daring discovered what had been discovered before. If there is an element of farce in what follows, the farce is at my own expense; for this book explains how I fancied I was the first to set foot in Brighton and then found I was the last. It recounts my elephantine adventures in pursuit of the obvious. No one can think my case more ludicrous than I think it myself; no reader can accuse me here of trying to make a fool of him: I am the fool of this story, and no rebel shall hurl me from my throne. I freely confess all the idiotic ambitions of the end of the nineteenth century. I did, like all other solemn little boys, try to be in advance of the age. Like them I tried to be some ten minutes in advance of the truth. And I found that I was eighteen hundred years behind it. I did strain my voice with a painfully juvenile exaggeration in uttering my truths. And I was punished in the fittest and funniest way, for I have kept my truths: but I have discovered, not that they were not truths, but simply that they were not mine. When I fancied that I stood alone I was really in the ridiculous position of being backed up by all Christendom. It may be, Heaven forgive me, that I did try to be original; but I only succeeded in inventing all by myself an inferior copy of the existing traditions of civilized religion. The man from the yacht thought he was the first to find England; I thought I was the first to find Europe. I did try to found a heresy of my own; and when I had put the last touches to it, I discovered that it was orthodoxy."

"Mere light sophistry is the thing that I happen to despise most of all things, and it is perhaps a wholesome fact that this is the thing of which I am generally accused. I know nothing so contemptible as a mere paradox; a mere ingenious defence of the indefensible. If it were true (as has been said) that Mr. Bernard Shaw lived upon paradox, then he ought to be a mere common millionaire; for a man of his mental activity could invent a sophistry every six minutes. It is as easy as lying; because it is lying. The truth is, of course, that Mr. Shaw is cruelly hampered by the fact that he cannot tell any lie unless he thinks it is the truth. I find myself under the same intolerable bondage."

"And if great reasoners are often maniacal, it is equally true that maniacs are commonly great reasoners. When I was engaged in a controversy with the Clarion on the matter of free will, that able writer Mr. R. B. Suthers said that free will was lunacy, because it meant causeless actions, and the actions of a lunatic would be causeless. I do not dwell here upon the disastrous lapse in determinist logic. Obviously if any actions, even a lunatics, can be causeless, determinism is done for. If the chain of causation can be broken for a madman, it can be broken for a man."
