Enneads VI.2: The Categories of Plotinos
Fundamental Unity of Genera Would Destroy Species; Manifoldness Must Pre-exist
Now that we have explained the existence of genera, which, besides, are principles of being, and that from another point of view there are principles (or elements), and compounds, we shall have to set forth the criterion by which we constitute these genera; we shall have to ask how they may be distinguished from each other, instead of reducing them to a single (principle), as if they had been united by chance, although it does indeed seem more rational to reduce them to a single (principle). It would be possible to reduce them in this way if all things were species of essence, if the individuals were contained within these species, and if there were nothing outside of these species. But such a supposition would destroy the species—for such species would no longer be species, or forms;—and from that moment there would be no further need for reducing plurality to unity, and everything forming a single unity; so that, all things belonging to this One, no being outside of the One would exist, as far as it was something else.
How indeed could the One have become manifold, and how could it have begotten the species, if nothing but it existed? For it would not be manifold if there were not something to divide it, such as a size; now that which divides is other than that which is divided. The mere fact that it divides itself, or imparts itself to others, shows that it was already divisible before the division.
THERE IS MORE THAN ONE GENUS, FOR NOT EVERYTHING CAN BE SUBSUMED UNDER BEING AND ESSENCE.
For this and other reasons, therefore, we must take good care to avoid assertion of a single genus; for it would be impossible to apply to everything the denominations of “being” and essence. If indeed there be very different objects called essence, this is only accidentally, just as if one called the color white a being; for strictly we cannot apply “being” to white, as considered alone.
THE ONE IS SO FAR ABOVE ALL THE GENERA AS NOT TO BE COUNTED.
3. We therefore assert the existence of several genera, and that this plurality is not accidental. These divers genera, however, depend from the One. But even though they do depend from the One, if the One be not something which may be affirmed of each of them as considered in its being, then nothing hinders each of them, having nothing similar to the others, from constituting a genus apart. We also grant that the One, existing outside of the genera which are begotten of Him, is their cause, although the other essences considered in their being do not proclaim this. Yes indeed, the One is outside of the other essences. Besides, He is above them; so much so, that He is not counted as one of them; for it is through Him that the other essences exist, which, so far as they are genera, are equal.
WE ARE DISCUSSING HERE NOT THE ABSOLUTE ONE, BUT THE ESSENTIAL RELATED ONE.
Still, it will be asked, Of what nature is the One which does not count among the genera? This (absolute One) is outside of our present consideration; for we are not studying Him who is above essence, but the essences themselves. We must therefore pass by the absolute One, and seek the one which is counted among the genera.
THE RELATED ONE IS IN SOME GENERA, BUT NOT IN OTHERS.
To begin with (if we consider the related One from this point of view), it will seem astonishing to see the cause numbered along with the effects. It would indeed be unreasonable to cram into a single genus both superior and inferior things. If nevertheless, on counting the one amidst the essences of which He is the cause, He was to be considered as a genus to which the other essences were to be subordinated, and from which they differed; if, besides, the one was not to be predicated of the other essences either as genus, or in any other respect, it would still be necessary that the genera which possessed essence subsume species under them; since, for instance, by moving, you produce walking, and yet walking cannot be considered a genus subordinate to you; but above the walking there existed nothing else that could, in respect to it, operate as a genus; and if nevertheless there existed things beneath walking, walking would, in respect to them, be a genus of the essences.
THE PARTS OF A MANIFOLD UNITY ARE APART ONLY FOR EXAMINATION.
Perhaps, instead of saying that the one is the cause of the other things, we would have to admit that these things are as parts and elements of the one; and that all things form a single nature in which only our thought establishes divisions; so that, by virtue of its admirable power, this nature be unity distributed in all things, appearing and becoming manifold, as if it were in movement, and that the one should cease being unity as a result of the fruitfulness of its nature. If we were to enumerate successively the parts of such a nature, we would grant to each of them a separate existence, ignoring that we had not seen the whole together. But after thus having separated the parts, we would soon reapproximate them, not for long being able to keep apart the isolated elements which tend to reunite. That is why we could not help making a whole out of them, letting them once more become unity, or rather, be unity. Besides, this will be easier to understand when we shall know what these essences are, and how many are the genera of essences; for we shall then be able to conceive their mode of existence. And as, in these matters, it is not well to limit oneself to negations, but to aim at positive knowledge, and at the full intelligence of the subject here treated, we shall have to make this inquiry.
THE GENERA OF ESSENCE WILL BE DETERMINED BY AN EXAMINATION OF THE PROBLEM OF THE ONE AND MANY.
4. If, on occupying ourselves with this sense-world, we wished to determine the nature of bodies, would we not begin by studying some part thereof, such as a stone? We could then distinguish therein substance, quantity—such as dimension—and quality, such as color; and after having discovered these same elements in other bodies, we could say that the elements of the corporeal nature are being, quantity, and quality; but that these three coexist; and that, though thought distinguish them, all three form but one and the same body. If, besides, we were to recognize that movement is proper to this same organization, would we not add it to the three elements already distinguished? These four elements, however, would form but a single one, and the body, though one, would, in its nature, be the reunion of all four. We shall have to take the same course with our present subject, intelligible Being, and its genera and principles. Only, in this comparison, we shall have to make abstraction of all that is peculiar to bodies, such as generation, sense-perception, and extension. After having established this separation, and having thus distinguished essentially different things, we shall arrive at the conception of a certain intelligible existence, which possesses real essence, and unity in a still higher degree. From this standpoint, one might be surprised how the (substance which is thus) one can be both one and many. In respect to bodies, it is generally recognized that the same thing is both one and many; the body can indeed be divided infinitely; color and appearance, for instance, are therein very differing properties, since they are separated here below. But in respect to the soul, if she be conceived as one, without extent, dimension and absolutely simple, as it appears at first sight, how could we, after that, believe that the soul were manifold? We should have here expected to reach unity, all the more as, after having divided the animal in body and soul, and after having demonstrated that the body is multiform, composite and diverse, one might well, on the contrary, have expected to find the soul simple; and to have accepted this conclusion as final, as the end of our researches. We would thus have taken the soul as a sample of the intelligible world, just as the body represents the sense-world. Having thus considered this soul, let us examine how this unity can be manifold; how, in its turn, the manifold can be unity; not indeed a composite formed of separable parts, but a single nature simultaneously one and manifold.
For, as we have already said, it is only by starting from this point and demonstrating it, that we will establish solidly the truth about the genera of essence.
