From the first chapter of Heretics:

Nothing more strangely indicates an enormous and silent evil of modern society than the extraordinary use which is made nowadays of the word “orthodox.” In former days the heretic was proud of not being a heretic. It was the kingdoms of the world and the police and the judges who were heretics. He was orthodox. He had no pride in having rebelled against them; they had rebelled against him. The armies with their cruel security, the kings with their cold faces, the decorous processes of State, the reasonable processes of law–all these like sheep had gone astray. The man was proud of being orthodox, was proud of being right. If he stood alone in a howling wilderness he was more than a man; he was a church. He was the centre of the universe; it was round him that the stars swung. All the tortures torn out of forgotten hells could not make him admit that he was heretical. But a few modern phrases have made him boast of it. He says, with a conscious laugh, “I suppose I am very heretical,” and looks round for applause. The word “heresy” not only means no longer being wrong; it practically means being clear-headed and courageous. The word “orthodoxy” not only no longer means being right; it practically means being wrong. All this can mean one thing, and one thing only. It means that people care less for whether they are philosophically right. For obviously a man ought to confess himself crazy before he confesses himself heretical. The Bohemian, with a red tie, ought to pique himself on his orthodoxy. The dynamiter, laying a bomb, ought to feel that, whatever else he is, at least he is orthodox.

It is foolish, generally speaking, for a philosopher to set fire to another philosopher in Smithfield Market because they do not agree in their theory of the universe. That was done very frequently in the last decadence of the Middle Ages, and it failed altogether in its object. But there is one thing that is infinitely more absurd and unpractical than burning a man for his philosophy. This is the habit of saying that his philosophy does not matter, and this is done universally in the twentieth century, in the decadence of the great revolutionary period. General theories are everywhere contemned; the doctrine of the Rights of Man is dismissed with the doctrine of the Fall of Man. Atheism itself is too theological for us to-day. Revolution itself is too much of a system; liberty itself is too much of a restraint. We will have no generalizations….

This was certainly not the idea of those who introduced our freedom. When the old Liberals removed the gags from all the heresies, their idea was that religious and philosophical discoveries might thus be made. Their view was that cosmic truth was so important that every one ought to bear independent testimony. The modern idea is that cosmic truth is so unimportant that it cannot matter what any one says. The former freed inquiry as men loose a noble hound; the latter frees inquiry as men fling back into the sea a fish unfit for eating. Never has there been so little discussion about the nature of men as now, when, for the first time, any one can discuss it. The old restriction meant that only the orthodox were allowed to discuss religion. Modern liberty means that nobody is allowed to discuss it. Good taste, the last and vilest of human superstitions, has succeeded in silencing us where all the rest have failed. Sixty years ago it was bad taste to be an avowed atheist. Then came the Bradlaughites, the last religious men, the last men who cared about God; but they could not alter it. It is still bad taste to be an avowed atheist. But their agony has achieved just this– that now it is equally bad taste to be an avowed Christian. Emancipation has only locked the saint in the same tower of silence as the heresiarch. Then we talk about Lord Anglesey and the weather, and call it the complete liberty of all the creeds.
