Thought control, like birth control, is best undertaken as long as possible before the fact. Many grown-ups will obstinately persist, if only now and then, in composing small strings of sentences in their heads and achieving at least momentary logic. This probably cannot be prevented, but we have learned how to minimize the consequences by arranging that such grown-ups will be unable to pursue that logic very far. If they were at home in the technology of writing, there's no telling how much social disorder they would cause by thinking things out at length.Our schools have chosen to cut this danger off as close to the root as possible, thus taking measures to preclude not only the birth of thought but its conception. They give the pill to even the youngest children, but just to be on the safe side, they give it to everybody else, too, especially all would-be schoolteachers.

It is perhaps not entirely so, though it has often been said, that man makes his God in his own image. Rather does he create Him in the image of his cravings and dreams- in the image of what man wants to be. God making could be part of the process by which a society realizes its aspirations: it first embodies them in the conception of a particular God, and then proceeds to imitate that God. The confidence requisite for attempting the unprecedented is most effectively generated by the fiction that in realizing the new we are imitating rather than originating. Our preoccupation with heaven can be part of an effort to find precedents for the unprecedented.
