“In my answer, I shall have to divide your question into two. First, it cannot be a moral truth, since it is not deduced from the consequences of human action. It can be simply a truth, that is, a fact. Secondly, it is not a self-evident truth, since it is not evident to all minds, and frequently becomes less and less evident, the more it is examined.”

“But is not the existence of a first or creating cause demonstrated to our senses, by all we see, and hear, and feel?”

“The existence of all that we see and hear and feel is demonstrated to our senses; and the belief we yield to this existence is immediate and irresistible, that is, intuitive.—The existence of the creating cause, that you speak of, is not demonstrated to our senses; and therefore the belief in it cannot be immediate and irresistible. I prefer the expression ‘creating’ to ‘first’ cause, because it seems to present a more intelligible meaning. When you shall have examined farther into the phenomena of nature, you will see, that there can be as little a first as a last cause.”

“But there must be always a cause, producing an effect?”

“Certainly; and so your cause,—creating all that we see and hear and feel—must itself have a producing cause, otherwise you are in the same difficulty as before.”

“I suppose it a Being unchangeable and eternal, itself unproduced, and producing all things.”

“Unchangeable it may be,—eternal it must be—since every thing is eternal.”

“Every thing eternal?”

“Yes; that is, the elements composing all substances are, so far as we know and can reason, eternal, and in their nature unchangeable; and it is apparently only the different disposition of these eternal and unchangeable atoms that produces all the varieties in the substances constituting the great material whole, of which we form a part. Those particles, whose peculiar agglomeration or arrangement, we call a vegetable to-day, pass into, and form part of, an animal to-morrow; and that animal again, by the falling asunder of its constituent atoms, and the different approximation and agglomeration of the same,—or, of the same with other atoms,—is transformed into some other substance presenting a new assemblage of qualities. To this simple exposition of the phenomena of nature (which, you will observe, is not explaining their wonders, for that is impossible, but only observing them,) we are led by the exercise of our senses. In studying the existences which surround us, it is clearly our business to use our eyes, and not our imaginations. To see things as they are, is all we should attempt, and is all that is possible to be done. Unfortunately, we can do but little even here, as our eyes serve us to see but a very little way. But, were our eyes better—were they so good as to enable us to observe all the arcana of matter, we could never acquire any other knowledge of them, than that they are as they are;—and, in knowing this, that is, in seeing every link in the chain of occurrences, we should know all that even an omniscient being could know. One astronomer traces the course of the sun round the earth, another imagines that of the earth round the sun. Some future improvements in science may enable us to ascertain which conjecture is the true one. We shall then have ascertained a fact, which fact may lead to the discovery of other facts, and so on. Until this plain and simple view of the nature of all science be generally received, all the advances we may make in it are comparatively as nothing. Until we occupy ourselves in examining, observing, and ascertaining, and not in explaining, we are idly and childishly employed.—With every truth we may discover we shall mix a thousand errors; and, for one matter of fact, we shall charge our brain with a thousand fancies. To this leading misconception of the real, and only possible object of philosophical enquiry, I incline to attribute all the modes and forms of human superstition. The vague idea that some mysterious cause not merely precedes but produces the effect we behold, occasions us to wander from the real object in search of an imaginary one. We see the sun rise in the east: Instead of confining our curiosity to the discovery of the time and manner of its rising, and of its course in the heavens, we ask also—why does it rise? What makes it move? The more ignorant immediately conceive some Being spurring it through the heavens, with fiery steeds, and on wheels of gold, while the more learned tell us of laws of motion, decreed by an almighty fiat, and sustained by an almighty will. Imagine the truth of both suppositions: In the one case, we should see the application of what we call physical power in the driver and the steeds followed by the motion of the sun, and in the other, an almighty volition followed by the motion of the sun. But, in either case, should we understand why the sun moved?—why or how its motion followed what we call the impulse of the propelling power, or the propelling volition? All that we could then know, more than we now know, would be, that the occurrence of the motion of the sun was preceded by another occurrence; and if we afterwards frequently observed the same sequence of occurrences, they would become associated in our mind as necessary precedent and consequent—as cause and effect: and we might give to them the appellation of law of nature, or any other appellation; but they would still constitute merely a truth—that is, a fact, and envelope no other mystery, than that involved in every occurrence and every existence.”

“But, according to this doctrine,” said Theon, “there would be no less reason in attributing the beautiful arrangement of the material world to the motion of a horse, than to the volition of an almighty mind.”
