ONE OF the most irrational of all the conventions of modern society is the one to the effect that religious opinions should be respected. It is largely to blame, I suspect, for the slowness with which sound ideas are disseminated in the world. The minute a new one bobs up some faction or other of theologians falls upon it furiously, seeking to put it down. The most effective way to defend it, of course, would be to fall upon the theologians, for the only really useful defense is an all-out offensive. But the convention aforesaid protects them, and so they proceed with their blather unwhipped and almost unmolested, to the great damage of common sense and common decency. That they should have this immunity is an outrage. There is nothing in religious ideas, as a class, to lift them above other ideas. On the contrary, they are always dubious and often quite silly. Nor is there any visible intellectual dignity in theologians. Few of them know anything that is worth knowing, and not many of them are even honest.
