THE SIX ENNEADS [41]
entities continue eternally unchanged in identity?"- evidently agreeing, in this matter also, with Herakleitos who maintained that even the sun is perpetually coming anew into being. To Aristotle there would be no problem; it is only accepting his theories of a fifth-substance. But to those who reject Aristotle's Quintessence and hold the material mass of the heavens to consist of the elements underlying the living things of this sphere, how is individual permanence possible? And the difficulty is still greater for the parts, for the sun and the heavenly bodies. Every living thing is a combination of soul and body-kind: the celestial sphere, therefore, if it is to be everlasting as an individual entity must be so in virtue either of both these constituents or of one of them, by the combination of soul and body or by soul only or by body only. Of course anyone that holds body to be incorruptible secures the desired permanence at once; no need, then, to call on a soul or on any perdurable conjunction to account for the continued maintenance of a living being. But the case is different when one holds that body is, of itself, perishable and that Soul is the principle of permanence: this view obliges us to the proof that the character of body is not in itself fatal either to the coherence or to the lasting stability which are imperative: it must be shown that the two elements of the union envisaged are not inevitably hostile, but that on the contrary [in the heavens] even Matter must conduce to the scheme of the standing result. 3. We have to ask, that is, how Matter, this entity of ceaseless flux constituting the physical mass of the universe, could serve towards the immortality of the Kosmos. And our answer is "Because the flux is not outgoing": where there is motion within but not outwards and the total remains unchanged, there is neither growth nor decline, and thus the Kosmos never ages. We have a parallel in our earth, constant from eternity to pattern and to mass; the air, too, never fails; and there is always water: all the changes of these elements leave unchanged the Principle of the total living thing, our world. In our own constitution, again, there is a ceaseless shifting of particles- and that with outgoing loss- and yet the individual persists for a long time: where there is no question of an outside region, the body-principle cannot clash with soul as against the identity and endless duration of the living thing. Of these material elements- for example- fire, the keen and swift, cooperates by its upward tendency as earth by its lingering below; for we must not imagine that the fire, once it finds itself at the point where its ascent must stop, settles down as in its appropriate place, no longer seeking, like all the rest, to expand in both directions. No: but higher is not possible; lower is repugnant to its Kind; all that remains for it is to be tractable and, answering to a need of its nature, to be drawn by the Soul to the activity of life, and so to move to in a glorious place, in the Soul. Anyone that dreads its falling may take heart; the circuit of the Soul provides against any declination, embracing, sustaining; and since fire has of itself no downward tendency it accepts that guiding without resistance. The partial elements constituting our persons do not suffice for their own cohesion; once they are brought to human shape, they must borrow elsewhere if the organism is to be maintained: but in the upper spheres since there can be no loss by flux no such replenishment is needed. Suppose such loss, suppose fire extinguished there, then a new fire must be kindled; so also if such loss by flux could occur in some of the superiors from which the celestial fire depends, that too must be replaced: but with such transmutations, while there might be something continuously similar, there would be, no longer, a Living All abidingly self-identical. 4. But matters are involved here which demand specific investigation and cannot be treated as incidental merely to our present
