The Teacher sighed gently at these words of mine, and then said; Maybe these were the objections, or such as these, that the Stoics and Epicureans collected at Athens made in answer to the Apostle. I hear that Epicurus carried his theories in this very direction. The framework of things was to his mind a fortuitous and mechanical affair, without a Providence penetrating its operations; and, as a piece with this, he thought that human life was like a bubble, existing only as long as the breath within was held in by the enveloping substance, inasmuch as our body was a mere membrane, as it were, encompassing a breath; and that on the collapse of the inflation the imprisoned essence was extinguished. To him the visible was the limit of existence; he made our senses the only means of our apprehension of things; he completely closed the eyes of his soul, and was incapable of seeing anything in the intelligible and immaterial world, just as a man, who is imprisoned in a cabin whose walls and roof obstruct the view outside, remains without a glimpse of all the wonders of the sky. Verily, everything in the universe that is seen to be an object of sense is as an earthen wall, forming in itself a barrier between the narrower souls and that intelligible world which is ready for their contemplation; and it is the earth and water and fire alone that such behold; whence comes each of these elements, in what and by what they are encompassed, such souls because of their narrowness cannot detect. While the sight of a garment suggests to any one the weaver of it, and the thought of the shipwright comes at the sight of the ship, and the hand of the builder is brought to the mind of him who sees the building, these little souls gaze upon the world, but their eyes are blind to Him whom all this that we see around us makes manifest; and so they propound their clever and pungent doctrines about the soul's evanishment;— body from elements, and elements from body, and, besides, the impossibility of the soul's self-existence (if it is not to be one of these elements, or lodged in one); for if these opponents suppose that by virtue of the soul not being akin to the elements it is nowhere after death, they must propound, to begin with, the absence of the soul from the fleshly life as well, seeing that the body itself is nothing but a concourse of those elements; and so they must not tell us that the soul is to be found there either, independently vivifying their compound. If it is not possible for the soul to exist after death, though the elements do, then, I say, according to this teaching our life as well is proved to be nothing else but death. But if on the other hand they do not make the existence of the soul now in the body a question for doubt, how can they maintain its evanishment when the body is resolved into its elements? Then, secondly, they must employ an equal audacity against the God in this Nature too. For how can they assert that the intelligible and immaterial Unseen can be dissolved and diffused into the wet and the soft, as also into the hot and the dry, and so hold together the universe in existence through being, though not of a kindred nature with the things which it penetrates, yet not thereby incapable of so penetrating them? Let them, therefore, remove from their system the very Deity Who upholds the world.
That is the very point, I said, upon which our adversaries cannot fail to have doubts; viz. that all things depend on God and are encompassed by Him, or, that there is any divinity at all transcending the physical world.
It would be more fitting, she cried, to be silent about such doubts, and not to deign to make any answer to such foolish and wicked propositions; for there is a Divine precept forbidding us to answer a fool in his folly; and he must be a fool, as the Prophet declares, who says that there is no God. But since one needs must speak, I will urge upon you an argument which is not mine nor that of any human being (for it would then be of small value, whosoever spoke it), but an argument which the whole Creation enunciates by the medium of its wonders to the audience of the eye, with a skilful and artistic utterance that reaches the heart. The Creation proclaims outright the Creator; for the very heavens, as the Prophet says, declare the glory of God with their unutterable words. We see the universal harmony in the wondrous sky and on the wondrous earth; how elements essentially opposed to each other are all woven together in an ineffable union to serve one common end, each contributing its particular force to maintain the whole; how the unmingling and mutually repellent do not fly apart from each other by virtue of their peculiarities, any more than they are destroyed, when compounded, by such contrariety; how those elements which are naturally buoyant move downwards, the heat of the sun, for instance, descending in the rays, while the bodies which possess weight are lifted by becoming rarefied in vapour, so that water contrary to its nature ascends, being conveyed through the air to the upper regions; how too that fire of the firmament so penetrates the earth that even its abysses feel the heat; how the moisture of the rain infused into the soil generates, one though it be by nature, myriads of differing germs, and animates in due proportion each subject of its influence; how very swiftly the polar sphere revolves, how the orbits within it move the contrary way, with all the eclipses, and conjunctions, and measured intervals of the planets. We see all this with the piercing eyes of mind, nor can we fail to be taught by means of such a spectacle that a Divine power, working with skill and method, is manifesting itself in this actual world, and, penetrating each portion, combines those portions with the whole and completes the whole by the portions, and encompasses the universe with a single all-controlling force, self-centred and self-contained, never ceasing from its motion, yet never altering the position which it holds.
And pray how, I asked, does this belief in the existence of God prove along with it the existence of the human soul? For God, surely, is not the same thing as the soul, so that, if the one were believed in, the other must necessarily be believed in.
She replied: It has been said by wise men that man is a little world in himself and contains all the elements which go to complete the universe. If this view is a true one (and so it seems), we perhaps shall need no other ally than it to establish the truth of our conception of the soul. And our conception of it is this; that it exists, with a rare and peculiar nature of its own, independently of the body with its gross texture. We get our exact knowledge of this outer world from the apprehension of our senses, and these sensational operations themselves lead us on to the understanding of the super-sensual world of fact and thought, and our eye thus becomes the interpreter of that almighty wisdom which is visible in the universe, and points in itself to the Being Who encompasses it. Just so, when we look to our inner world, we find no slight grounds there also, in the known, for conjecturing the unknown; and the unknown there also is that which, being the object of thought and not of sight, eludes the grasp of sense.
I rejoined, Nay, it may be very possible to infer a wisdom transcending the universe from the skilful and artistic designs observable in this harmonized fabric of physical nature; but, as regards the soul, what knowledge is possible to those who would trace, from any indications the body has to give, the unknown through the known?
