The special mark of the modern world is not that it is skeptical, but that it is dogmatic without knowing it. It says, in mockery of old devotees, that they believed without knowing why they believed. But the moderns believe without knowing what they believe—and without even knowing that they do believe it. Their freedom consists in first freely assuming a creed, and then freely forgetting that they are assuming it. In short, they always have an unconscious dogma…Their thoughts will work out to most interesting conclusions; but they can never tell you anything about their beginnings. They have always taken away the number they first thought of. They have always forgotten the very fact or fancy on which their whole theory depends.
–G.K. Chesterton, “The Debate on Spiritualism”
