(12) For, after dividing "the animal" into mortal and immortal, then into terrestrial and aquatic; and the terrestrial again into those who fly and those who walk; and so dividing the species which is nearest to what is sought, which also contains what is sought, we arrive by division at the simplest species, which contains nothing else, but what is sought alone.

(14) But the question was, whether the embryo is already an animal, or still a plant. And then the name animal was reduced to definition, for the sake of perspicuity. But having discovered that it is distinguished from what is not an animal by sensation and motion from appetency; we again separated this from its adjuncts; asserting that it was one thing for that to be such potentially, which is not yet possessed of the power of sensation and motion, but will some time be so, and another thing to be already so actually; and in the case of such, it is one thing to exert its powers, another to be able to exert them, but to be at rest or asleep. And this is the question.

(19) Having established our four primary genera, it remains for us to enquire whether each of them of itself alone produces species. And especially, can Being be divided independently, that is without drawing upon the other genera? Surely not: the differentiae must come from outside the genus differentiated: they must be differentiae of Being proper, but cannot be identical with it.

Where then is it to find them? Obviously not in non-beings. If then in beings, and the three genera are all that is left, clearly it must find them in these, by conjunction and couplement with these, which will come into existence simultaneously with itself.

But if all come into existence simultaneously, what else is produced but that amalgam of all Existents which we have just considered ? How can other things exist over and above this all-including amalgam? And if all the constituents of this amalgam are genera, how do they produce species? How does Motion produce species of Motion? Similarly with Stability and the other genera.

A word of warning must here be given against sinking the various genera in their species; and also against reducing the genus to a mere predicate, something merely seen in the species. The genus must exist at once in itself and in its species; it blends, but it must also be pure; in contributing along with other genera to form Substance, it must not destroy itself. There are problems here that demand investigation.

But since we identified the amalgam of the Existents with the particular intellect, Intellect as such being found identical with Being or Substance, and therefore prior to all the Existents, which may be regarded as its species or members, we may infer that the intellect, considered as completely unfolded, is a subsequent.

Our treatment of this problem may serve to promote our investigation; we will take it as a kind of example, and with it embark upon our enquiry.

(11) We divide, therefore, the genus of what is proposed for consideration into the species contained in it; as, in the case of man, we divide animal, which is the genus, into the species that appear in it, the mortal, and the immortal. And thus, by continually dividing those genera that seem to be compound into the simpler species, we arrive at the point which is the subject of investigation, and which is incapable of further division.

(8) As then there is a Life-Form primal- which therefore is the Life-Form Absolute- and there is Intellectual-Principle or Being, Authentic Being, these, we affirm, contain all living things and all Number, and Absolute Justice and Beauty and all of that order; for we ascribe an existence of their own to Absolute Man, Absolute Number, Absolute Justice. It remains to discover, in so far as such knowledge is possible, how these distinct entities come to be and what is the manner of their being.

At the outset we must lay aside all sense-perception; by Intellectual-Principle we know Intellectual-Principle. We reflect within ourselves there is life, there is intellect, not in extension but as power without magnitude, issue of Authentic Being which is power self-existing, no vacuity but a thing most living and intellective- nothing more living, more intelligent, more real- and producing its effect by contact and in the ratio of the contact, closely to the close, more remotely to the remote. If Being is to be sought, then most be sought is Being at its intensest; so too the intensest of Intellect if the Intellectual act has worth; and so, too, of Life.

First, then, we take Being as first in order; then Intellectual-Principle; then the Living-Form considered as containing all things: Intellectual-Principle, as the Act of Real Being, is a second.

Thus it is clear that Number cannot be dependent upon the Living-Form since unity and duality existed before that; nor does it rise in the Intellectual-Principle since before that there existed Real Being which is both one and numerous.

(25) Thus all creatures are relatively ignorant yet relatively wise; comparatively nothing yet comparatively all. The microscope reveals to man his significance; the telescope, his insignificance. Through the eternities of existence man is gradually increasing in both wisdom and understanding; his ever-expanding consciousness is including more of the external within the area of itself. Even in man's present state of imperfection it is dawning upon his realization that he can never be truly happy until he is perfect, and that of all the faculties contributing to his self-perfection none is equal in importance to the rational intellect. Through the labyrinth of diversity only the illumined mind can, and must, lead the soul into the perfect light of unity.

(8) From this basis we proceed:

In the advancing stages of Contemplation rising from that in Nature, to that in the Soul and thence again to that in the Intellectual-Principle itself- the object contemplated becomes progressively a more and more intimate possession of the Contemplating Beings, more and more one thing with them; and in the advanced Soul the objects of knowledge, well on the way towards the Intellectual-Principle, are close to identity with their container.

Hence we may conclude that, in the Intellectual-Principle Itself, there is complete identity of Knower and Known, and this not by way of domiciliation, as in the case of even the highest soul, but by Essence, by the fact that, there, no distinction exists between Being and Knowing; we cannot stop at a principle containing separate parts; there must always be a yet higher, a principle above all such diversity.

The Supreme must be an entity in which the two are one; it will, therefore, be a Seeing that lives, not an object of vision like things existing in something other than themselves: what exists in an outside element is some mode of living-thing; it is not the Self-Living.

Now admitting the existence of a living thing that is at once a Thought and its object, it must be a Life distinct from the vegetative or sensitive life or any other life determined by Soul.

In a certain sense no doubt all lives are thoughts- but qualified as thought vegetative, thought sensitive and thought psychic.

What, then, makes them thoughts?

The fact that they are Reason-Principles. Every life is some form of thought, but of a dwindling clearness like the degrees of life itself. The first and clearest Life and the first Intelligence are one Being. The First Life, then, is an Intellection and the next form of Life is the next Intellection and the last form of Life is the last form of Intellection. Thus every Life, of the order strictly so called, is an Intellection.

But while men may recognize grades in life they reject grade in thought; to them there are thoughts and anything else is no thought.

This is simply because they do not seek to establish what Life is.

The essential is to observe that, here again, all reasoning shows that whatever exists is a bye-work of visioning: if, then, the truest Life is such by virtue of an Intellection and is identical with the truest Intellection, then the truest Intellection is a living being; Contemplation and its object constitute a living thing, a Life, two inextricably one.

The duality, thus, is a unity; but how is this unity also a plurality?

The explanation is that in a unity there can be no seeing ; and in its Contemplation the One is not acting as a Unity; if it were, the Intellectual-Principle cannot exist. The Highest began as a unity but did not remain as it began; all unknown to itself, it became manifold; it grew, as it were, pregnant: desiring universal possession, it flung itself outward, though it were better had it never known the desire by which a Secondary came into being: it is like a Circle which in projection becomes a figure, a surface, a circumference, a centre, a system of radii, of upper and lower segments. The Whence is the better; the Whither is less good: the Whence is not the same as the Whence-followed-by-a-Whither; the Whence all alone is greater than with the Whither added to it.

The Intellectual-Principle on the other hand was never merely the Principle of an inviolable unity; it was a universal as well and, being so, was the Intellectual-Principle of all things. Being, thus, all things and the Principle of all, it must essentially include this part of itself which is universal and is all things: otherwise, it contains a part which is not Intellectual-Principle: it will be a juxtaposition of non-Intellectuals, a huddled heap waiting to be made over from the mass of things into the Intellectual-Principle!

We conclude that this Being is limitless and that, in all the outflow from it, there is no lessening either in its emanation, since this also is the entire universe, nor in itself, the starting point, since it is no assemblage of parts .

(2) Such, then, is the method of the discovery [of truth]. For we must begin with the knowledge of the questions to be discussed. For often the form of the expression deceives and confuses and disturbs the mind, so that it is not easy to discover to what class the thing is to be referred; as, for example, whether the foetus be an animal. For, having a conception of an animal and a foetus, we inquire if it be the case that the foetus is an animal; that is, if the substance which is in the foetal state possesses the power of motion, and of sensation besides. So that the inquiry is regarding functions and sensations in a substance previously known. Consequently the man who proposes the question is to be first asked, what he calls an animal. Especially is this to be done whenever we find the same term applied to various purposes; and we must examine whether what is signified by the term is disputed, or admitted by all. For were one to say that he calls whatever grows and is fed an animal, we shall have again to ask further, whether he considered plants to be animals; and then, after declaring himself to this effect, he must show what it is which is in the foetal state, and is nourished.

(4) Now, on the man who proposes the question denying that plants are animals, we shall show that he affirms what contradicts himself. For, having defined the animal by the fact of its nourishment and growth, but having asserted that a plant is not an animal, it appears that he says nothing else than that what is nourished and grows is both an animal and not an animal.

(15) For the embryo is not to be called an animal from the fact that it is nourished; which is the allegation of those who turn aside from the essence of the question, and apply their minds to what happens otherwise. But in the case of all conclusions alleged to be found out, demonstration is applied in common, which is discourse (logos), establishing one thing from others. But the grounds from which the point in question is to be established, must be admitted and known by the learner. And the foundation of all these is what is evident to sense and to intellect.

(29) the Corporeal Intelligence, so called because it forms every body which is, formed beneath the whole set of worlds and the increment of them.

(20) We may thus distinguish two phases of Intellect, in one of which it may be taken as having no contact whatever with particulars and no Act upon anything; thus it is kept apart from being a particular intellect. In the same way science is prior to any of its constituent species, and the specific science is prior to any of its component parts: being none of its particulars, it is the potentiality of all; each particular, on the other hand, is actually itself, but potentially the sum of all the particulars: and as with the specific science, so with science as a whole. The specific sciences lie in potentiality in science the total; even in their specific character they are potentially the whole; they have the whole predicated of them and not merely a part of the whole. At the same time, science must exist as a thing in itself, unharmed by its divisions.

So with Intellect. Intellect as a whole must be thought of as prior to the intellects actualized as individuals; but when we come to the particular intellects, we find that what subsists in the particulars must be maintained from the totality. The Intellect subsisting in the totality is a provider for the particular intellects, is the potentiality of them: it involves them as members of its universality, while they in turn involve the universal Intellect in their particularity, just as the particular science involves science the total.

The great Intellect, we maintain, exists in itself and the particular intellects in themselves; yet the particulars are embraced in the whole, and the whole in the particulars. The particular intellects exist by themselves and in another, the universal by itself and in those. All the particulars exist potentially in that self-existent universal, which actually is the totality, potentially each isolated member: on the other hand, each particular is actually what it is , potentially the totality. In so far as what is predicated of them is their essence, they are actually what is predicated of them; but where the predicate is a genus, they are that only potentially. On the other hand, the universal in so far as it is a genus is the potentiality of all its subordinate species, though none of them in actuality; all are latent in it, but because its essential nature exists in actuality before the existence of the species, it does not submit to be itself particularized. If then the particulars are to exist in actuality- to exist, for example, as species- the cause must lie in the Act radiating from the universal.

(4) and endowed with their intelligent rational principles, it bears the male Intellect Protophanes as an image, and acts within the Individuals either with craft or with skill or with partial instinct;

(1) And all dependent from Above are subdivided into species in the fashion which I am to tell. The genera of all things company with their own species; so that the genus is a class in its entirety, the species is part of a genus. The genus of the Gods will, therefore, make the species of the Gods out of itself. In like way, too, the genus of the daimons, and of men, likewise of birds, and of all [animals] the Cosmos doth contain within itself, brings into being species like itself. There is besides a genus other than the animal,—a genus, or indeed a soul, in that it’s not without sensation,—in consequence of which it both finds happiness in suitable conditions, and pines and spoils in adverse ones;—I mean [the class] of all things on the earth which owe their life to the sound state of roots and shoots, of which the various kinds are scattered through the length and breadth of Earth.

(3) From It, both all living creatures and plants draw their life and nourishment; and whether you speak of intellectual, or rational, or sensible, or nourishing, or growing, or whatever, life, or source of life, or essence of life, from It, which is above every life, it both lives and thrives; and in It, as Cause, uniformly pre-existed. For the super-living, and life-springing Life is Cause both of all life, and is generative, and completive, and dividing of life, and is to be celebrated from every life, in consequence of its numerous generation of all lives, as Manifold, and contemplated, and sung by every life; and as without need, yea, rather, superfull of life, the Self-living, and above every life, causing to live and super-living, or in whatever way one might extol the life which is unutterable by human speech.

(7) It is inevitably necessary to think of all as contained within one nature; one nature must hold and encompass all; there cannot be as in the realm of sense thing apart from thing, here a sun and elsewhere something else; all must be mutually present within a unity. This is the very nature of the Intellectual-Principle as we may know from soul which reproduces it and from what we call Nature under which and by which the things of process are brought into their disjointed being while that Nature itself remains indissolubly one.

But within the unity There, the several entities have each its own distinct existence; the all-embracing Intellect sees what is in it, what is within Being; it need not look out upon them since it contains them, need not separate them since they stand for ever distinct within it.

Against doubters we cite the fact of participation; the greatness and beauty of the Intellectual-Principle we know by the soul's longing towards it; the longing of the rest towards soul is set up by its likeness to its higher and to the possibility open to them of attaining resemblance through it.

It is surely inconceivable that any living thing be beautiful failing a Life-Absolute of a wonderful, an ineffable, beauty: this must be the Collective Life, made up of all living things, or embracing all, forming a unity coextensive with all, as our universe is a unity embracing all the visible.

(1) We have now explained our conception of Reality and considered how far it agrees with the teaching of Plato. We have still to investigate the opposed principle .

There is the possibility that the genera posited for the Intellectual sphere will suffice for the lower also; possibly with these genera others will be required; again, the two series may differ entirely; or perhaps some of the sensible genera will be identical with their intellectual prototypes, and others different- "identical," however, being understood to mean only analogous and in possession of a common name, as our results will make dear.

We must begin on these lines:

The subject of our discussion is the Sensible realm: Sensible Existence is entirely embraced by what we know as the Universe: our duty, then, would seem to be clear enough- to take this Universe and analyse its nature, classifying its constituent parts and arranging them by species. Suppose that we were making a division of speech: we should reduce its infinity to finite terms, and from the identity appearing in many instances evolve a unity, then another and another, until we arrived at some definite number; each such unit we should call a species if imposed upon individuals, a genus if imposed upon species. Thus, every species of speech- and similarly all phenomena- might be referred to a unity; speech- or element- might be predicated of them all.

This procedure however is as we have already shown, impossible in dealing with the subject of our present enquiry. New genera must be sought for this Universe-genera distinct from those of the Intellectual, inasmuch as this realm is different from that, analogous indeed but never identical, a mere image of the higher. True, it involves the parallel existence of Body and Soul, for the Universe is a living form: essentially however Soul is of the Intellectual and does not enter into the structure of what is called Sensible Being.

Remembering this fact, we must- however great the difficulty- exclude Soul from the present investigation, just as in a census of citizens, taken in the interests of commerce and taxation, we should ignore the alien population. As for the experiences to which Soul is indirectly subject in its conjunction with Body and by reason of Body's presence, their classification must be attempted at a later stage, when we enquire into the details of Sensible Existence.

(26) We may now take the various specific types of Motion, such as locomotion, and once again enquire for each one whether it is not to be divided on the basis of direction, up, down, straight, circular- a question already raised; whether the organic motion should be distinguished from the inorganic- they are clearly not alike; whether, again, organic motions should be subdivided into walking, swimming and flight.

Perhaps we should also distinguish, in each species, natural from unnatural motions: this distinction would however imply that motions have differences which are not external. It may indeed be the case that motions create these differences and cannot exist without them; but Nature may be supposed to be the ultimate source of motions and differences alike.

Motions may also be classed as natural, artificial and purposive: "natural" embracing growth and decay; "artificial" architecture and shipbuilding; "purposive" enquiry, learning, government, and, in general, all speech and action.

Again, with regard to growth, alteration and birth, the division may proceed from the natural and unnatural, or, speaking generally, from the characters of the moved objects.

(1) And yet the species of all genera are interblended with all genera; some which have previously been made, some which are made from these. The latter, then, which are being made,—either by Gods, or daimons, or by men,—are species all most closely like to their own several genera. For that it is impossible that bodies should be formed without the will of God; or species be configured without the help of daimons; or animals be taught and trained without the help of men.

(6) We take it, then, that the Intellectual-Principle is the authentic existences and contains them all- not as in a place but as possessing itself and being one thing with this its content. All are one there and yet are distinct: similarly the mind holds many branches and items of knowledge simultaneously, yet none of them merged into any other, each acting its own part at call quite independently, every conception coming out from the inner total and working singly. It is after this way, though in a closer unity, that the Intellectual-Principle is all Being in one total- and yet not in one, since each of these beings is a distinct power which, however, the total Intellectual-Principle includes as the species in a genus, as the parts in a whole. This relation may be illustrated by the powers in seed; all lies undistinguished in the unit, the formative ideas gathered as in one kernel; yet in that unit there is eye-principle, and there is hand-principle, each of which is revealed as a separate power by its distinct material product. Thus each of the powers in the seed is a Reason-Principle one and complete yet including all the parts over which it presides: there will be something bodily, the liquid, for example, carrying mere Matter; but the principle itself is Idea and nothing else, idea identical with the generative idea belonging to the lower soul, image of a higher. This power is sometimes designated as Nature in the seed-life; its origin is in the divine; and, outgoing from its priors as light from fire, it converts and shapes the matter of things, not by push and pull and the lever work of which we hear so much, but by bestowal of the Ideas.
