Context: It is probably safe to say that at one time, or during one phase of the development of man, everything was miraculous. After a time, the mind slowly developing, certain phenomena, always happening under like conditions, were called “natural,” and none suspected any special interference. The domain of the miraculous grew less and less—the domain of the natural larger; that is to say, the common became the natural, but the uncommon was still regarded as the miraculous. The rising and setting of the sun ceased to excite the wonder of mankind—there was no miracle about that; but an eclipse of the sun was miraculous. Men did not then know that eclipses are periodical, that they happen with the same certainty that the sun rises. It took many observations through many generations to arrive at this conclusion. Ordinary rains became “natural,” floods remained “miraculous.” But it can all be summed up in this: The average man regards the common as natural, the uncommon as supernatural. The educated man—and by that I mean the developed man—is satisfied that all phenomena are natural, and that the supernatural does not and can not exist.

Context: All government, in its essence, is a conspiracy against the superior man: its one permanent object is to oppress him and cripple him. If it be aristocratic in organization, then it seeks to protect the man who is superior only in law against the man who is superior in fact; if it be democratic, then it seeks to protect the man who is inferior in every way against both. One of its primary functions is to regiment men by force, to make them as much alike as possible and as dependent upon one another as possible, to search out and combat originality among them. All it can see in an original idea is potential change, and hence an invasion of its prerogatives. The most dangerous man to any government is the man who is able to think things out for himself, without regard to the prevailing superstitions and taboos. Almost inevitably he comes to the conclusion that the government he lives under is dishonest, insane and intolerable, and so, if he is romantic, he tries to change it. And even if he is not romantic personally he is very apt to spread discontent among those who are.
