“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.”
Rome, or Reason? A Reply to Cardinal Manning. Part I. The North American Review (1888)
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.

The New Divinity (1964)
Context: The entire cosmos is made out of one and the same world-stuff, operated by the same energy as we ourselves. "Mind" and "matter" appears as two aspects of our unitary mind-bodies. There is no separate supernatural realm: all phenomena are part of one natural process of evolution. There is no basic cleavage between science and religion; they are both organs of evolving humanity.
