(3.) Of the nature of the soul. From the material quality assigned to the soul by the early Ionian schools, as that it was air, fire, or the like, there was a gradual passage to the opinion of its immateriality. To this, precision was given by the assertion that it had not only an affinity with, but even is a part of God. Whatever were the views entertained of the nature and attributes of the Supreme Being, they directly influenced the conclusions arrived at respecting the nature of the soul.

Its immortality and final absorption.

Greek philosophy, in its highest state of development, regarded the soul as something more than the sum of the moments of thinking. It held it to be a portion of the Deity himself. This doctrine is the necessary corollary of Pantheism. It contemplated a past eternity, a future immortality. It entered on such inquiries as whether the number of souls in the universe is constant. As upon the foregoing point, so upon this: there was a complete analogy between the decision arrived at in Grecian and that in Indian philosophy. Thus the latter says, "I am myself an irradiated manifestation of the supreme Brahm." "Never was there a time in which I was not, nor thou, nor these princes of the people, and never shall I not be; henceforth we all are." Viewing the soul as merely a spectator and stranger in this world, they regarded it as occupying itself rather in contemplation than in action, asserting that in its origin it is an immediate emanation from the Divinity—not a modification nor a transformation of the Supreme, but a portion of him; "its relation is not that of a servant to his master, but of a part to the whole." It is like a spark separated from a flame; it migrates from body to body, sometimes found in the higher, then in the lower, and again in the higher tribes of life, occupying first one, then another body, as circumstances demand. And, as a drop of water pursues a devious career in the cloud, in the rain, in the river, a part of a plant, or a part of an animal, but sooner or later inevitably finds its way back to the sea from which it came, so the soul, however various its fortunes may have been, sinks back at last into the divinity from which it emanated.

Both Greeks and Hindus turned their attention to the delusive phenomena of the world. Among the latter many figuratively supposed that what we call visible nature is a mere illusion befalling the soul, because of its temporary separation from God. In the Buddhist philosophy the world is thus held to be a creature of the imagination. But among some in those ancient, as among others in more modern times, it was looked upon as having a more substantial condition, and the soul as a passive mirror in which things reflected themselves, or perhaps it might, to some extent, be the partial creator of its own forms. However that may be, its final destiny is a perfect repose after its absorption in the Supreme.

Illustration of the nature of the soul.

On this third topic of ancient philosophy an illustration may not be without use. As a bubble floats upon the sea, and, by reason of its form, reflects whatever objects may be present, whether the clouds in the sky, or the stationary and moving things on the shore, nay, even to a certain extent depicts the sea itself on which it floats, and from which it arose, offering these various forms not only in shapes resembling the truth in the proper order of light and shade, the proper perspective, the proper colours, but, in addition thereto, tincturing them all with a play of hues arising from itself, so it is with the soul. From a boundless and unfathomable sea the bubble arose. It does not in any respect differ in nature from its source. From water it came, and mere water it ever is. It gathers its qualities, so far as external things are concerned, only from its form, and from the environment in which it is placed. As the circumstances to which it is exposed vary, it floats here and there, merging into other bubbles it meets, and emerging from the collected foam again. In such migrations it is now larger, now smaller; at one moment passing into new shapes, at another lost in a coalescence with those around it. But whatever these its migrations, these its vicissitudes, there awaits it an inevitable destiny, an absorption, a re-incorporation with the ocean. In that final moment, what is it that is lost? what is it that has come to an end? Not the essential substance, for water it was before it was developed, water it was during its existence, and water it still remains, ready to be re-expanded.

Nor does the resemblance fail when we consider the general functions discharged while the bubble maintained its form. In it were depicted in their true shapes and relative magnitudes surrounding things. It hence had a relation to Space. And, if it was in motion, it reflected in succession the diverse objects as they passed by. Through such successive representations it maintained a relation to Time. Moreover, it imparted to the images it thus produced a coloration of its own, and in all this was an emblem of the Soul. For Space and Time are the outward conditions with which it is concerned, and it adds thereto abstract ideas, the product of its own nature.

Its continued existence—its Nirwana.

But when the bubble bursts there is an end of all these relations. No longer is there any reflection of external forms, no longer any motion, no longer any innate qualities to add. In one respect the bubble is annihilated, in another it still exists. It has returned to that infinite expanse in comparison with which it is altogether insignificant and imperceptible. Transitory, and yet eternal: transitory, since all its relations of a special and individual kind have come to an end; eternal in a double sense—the sense of Platonism—since it was connected with a past of which there was no beginning, and continues in a future to which there is no end.

As to the criterion of truth—sense-delusions.
