(2) In the first place, therefore, we shall divide the genera of the proposed problems, in order that we may know the quantity and quality of them. And, in the next place, we shall show from what theologies the doubts are assumed, and according to what sciences they are investigated. For some things that are badly confused, require a certain distinction; others are conversant with the cause through which they subsist, and are apprehended; others, which we propose according to a certain contrariety, draw our decision on both sides; and some things require from us the whole development of mystic doctrines. Such, therefore, being the nature of the subjects of discussion, they are assumed from many places, and from different sciences. For some things introduce animadversions from what the wise men of the Chaldeans have delivered; others produce objections from what the prophets of the Egyptians teach; and there are some that, adhering to the theory of philosophers, make inquiries conformably to them. There are now likewise some, that from other opinions, which do not deserve to be mentioned, elicite a certain dubitation; and others originate from the common conceptions of mankind. These things, therefore, are of themselves variously disposed, and are multiformly connected with each other. Hence, through all these causes, a certain discussion is requisite for the management of them in a becoming manner.

(2) But indications of this theory worthy of notice may be mentioned, by which it is possible for you, and those who resemble you, to be conducted by intellect to the essence of [real] beings. And with respect to such things as become known by a reasoning process, we shall leave no one of these without a perfect demonstration. But in all things we shall give to each that which is appropriate. And such questions, indeed, as are theological, we shall answer theologically; such as are theurgic, theurgically; but such as are philosophical, we shall, in conjunction with you, philosophically explore. Of these, also, such as extend to first causes, we shall unfold into light, by following them conformably to first principles. But such as pertain to morals, or to ends, we shall fitly discuss, according to the ethical mode. And, in a similar manner, we shall examine other things methodically and appropriately. Let us, therefore, now betake ourselves to your inquiries.

(2) Now the reasoning faculty which undertakes this problem is not a unity but a thing of parts; it brings the bodily nature into the enquiry, borrowing its principles from the corporeal: thus it thinks of the Essential Existence as corporeal and as a thing of parts; it baulks at the unity because it does not start from the appropriate principles. We, however, must be careful to bring the appropriately convincing principles to the discussion of the Unity, of perfect Being: we must hold to the Intellectual principles which alone apply to the Intellectual Order and to Real Being.

On the one hand there is the unstable, exposed to all sorts of change, distributed in place, not so much Being as Becoming: on the other, there is that which exists eternally, not divided, subject to no change of state, neither coming into being nor falling from it, set in no region or place or support, emerging from nowhere, entering into nothing, fast within itself.

In dealing with that lower order we would reason from its own nature and the characteristics it exhibits; thus, on a plausible foundation, we achieve plausible results by a plausible system of deduction: similarly, in dealing with the Intellectual, the only way is to grasp the nature of the essence concerned and so lay the sure foundations of the argument, not forgetfully straying over into that other order but basing our treatment on what is essential to the Nature with which we deal.

In every entity the essential nature is the governing principle and, as we are told, a sound definition brings to light many even of the concomitants: where the essential nature is the entire being, we must be all the more careful to keep to that, to look to that, to refer all to that.

(532) even with their weak eyes the images 6 in the water (which are divine), and are the shadows of true existence (not shadows of images cast by a light of fire, which compared with the sun is only an image)—this power of elevating the highest principle in the soul to the contemplation of that which is best in existence, with which we may compare the raising of that faculty which is the very light of the body to the sight of that which is brightest in the material and visible world—this power is given, as I was saying, by all that study and pursuit of the arts which has been described. I agree in what you are saying, he replied, which may be hard to believe, yet, from another point of view, is harder still to deny. This, however, is not a theme to be treated of in passing only, but will have to be discussed again and again. And so, whether our conclusion be true or false, let us assume all this, and proceed at once from the prelude or preamble to the chief strain 7 , and describe that in like manner. Say, then, what is the nature and what are the divisions of dialectic, and what are the paths which lead thither; for these paths will also lead to our final rest.

(1) Let us then, in the next place, consider the opposing arguments, what they are, and what reason they possess. And if we should discuss some things a little more abundantly, in consequence of speaking freely and at leisure, it is requisite that you should promptly attend to, and endure what, we say. For it is necessary that great labour should be bestowed on the greatest disciplines, and that they should be accurately explored for a long time, if you intend to know them perfectly. Do you, therefore, conformably to the present hypothesis, propose the arguments which occasion the doubt, and I will answer you. Say then, “ it very much perplexes me to understand how superior beings, when invoked, are commanded by those that invoke them, as if they were their inferiors .” But I will unfold to you the whole division, which is worthy of regard, concerning the powers that are invoked; from which you will be able clearly to define what is possible and what is impossible, in the subjects of your investigation. For the Gods, indeed, and the natures that are more excellent than we, through the wish of what is beautiful, and from an unenvying and exuberant fulness of good, benevolently impart to those that are worthy, such things as are fit for them, commiserating the labours of sacerdotal men, but being delighted with those that they have begotten, nourished, and instructed. But the middle genera are the inspective guardians of judgment.

(1) But the inquiries which follow in the next place, require a more abundant doctrine, in order to their elucidation. At the same time, however, it is necessary to discuss the truth concerning them with brevity. For you inquire “ what efficacy there is in names that are not significant .” They are not, however, as you think, without signification; but let them be indeed unknown to us (though some of them are known to us, the explications of which we receive from the Gods), yet to the Gods all of them are significant, though not according to an effable mode; nor in such a way as that which is significant and indicative with men through imaginations; but either intellectually, conformably to the divine intellect which is in us; or ineffably, and in a way more excellent and simple, and conformably to the intellect which is united to the Gods. It is requisite, therefore, to take away all conceptions derived by an abstraction from sensibles, and all logical evolutions from divine names; and likewise the connascent physical similitudes of language to things which exist in nature. But the intellectual and divine symbolical character of divine similitude must be admitted to have a subsistence in names.

(4) Hence, through these things such a corporeal-formed division as you introduce, is demonstrated to be false. It is, indeed, especially necessary not to propose any thing of this kind; but if this should appear to you to be requisite, yet you must not think, that what is false deserves to be discussed. For such a discussion does not exhibit a copiousness of arguments; but he wearies himself in vain, who, proposing things that are false, endeavours afterwards to subvert them, as things that are not true. For how is it possible that an essence, which is of itself incorporeal, and which has nothing in common with the bodies that participate of it, should be distinguished from other things by corporeal qualities? How can that which is not locally present with bodies, be separated by corporeal places? And how can that which is not inclosed by the partible circumscriptions of subjects, be partibly detained by the parts of the world? What, also, is that which can prevent the Gods from being every where? And what can restrain their power from extending as far as to the celestial arch? For to effect this, must be the work of a more powerful cause, which is able to inclose and circumscribe them in certain parts.

(4) If we had to ascertain the nature of body and the place it holds in the universe, surely we should take some sample of body, say stone, and examine into what constituents it may be divided. There would be what we think of as the substrate of stone, its quantity- in this case, a magnitude; its quality- for example, the colour of stone. As with stone, so with every other body: we should see that in this thing, body, there are three distinguishable characteristics- the pseudo-substance, the quantity, the quality- though they all make one and are only logically trisected, the three being found to constitute the unit thing, body. If motion were equally inherent in its constitution, we should include this as well, and the four would form a unity, the single body depending upon them all for its unity and characteristic nature.

The same method must be applied in examining the Intellectual Substance and the genera and first-principles of the Intellectual sphere.

But we must begin by subtracting what is peculiar to body, its coming-to-be, its sensible nature, its magnitude- that is to say, the characteristics which produce isolation and mutual separation. It is an Intellectual Being we have to consider, an Authentic Existent, possessed of a unity surpassing that of any sensible thing.

Now the wonder comes how a unity of this type can be many as well as one. In the case of body it was easy to concede unity-with-plurality; the one body is divisible to infinity; its colour is a different thing from its shape, since in fact they are separated. But if we take Soul, single, continuous, without extension, of the highest simplicity- as the first effort of the mind makes manifest- how can we expect to find multiplicity here too? We believed that the division of the living being into body and soul was final: body indeed was manifold, composite, diversified; but in soul we imagined we had found a simplex, and boldly made a halt, supposing that we had come to the limit of our course.

Let us examine this soul, presented to us from the Intellectual realm as body from the Sensible. How is its unity a plurality? How is its plurality a unity? Clearly its unity is not that of a composite formed from diverse elements, but that of a single nature comprising a plurality.

This problem attacked and solved, the truth about the genera comprised in Being will thereby, as we asserted, be elucidated also.

(1) The Intellectual-Principle, the veritably and essentially intellective, can this be conceived as ever falling into error, ever failing to think reality?

Assuredly no: it would no longer be intelligent and therefore no longer Intellectual-Principle: it must know unceasingly- and never forget; and its knowledge can be no guesswork, no hesitating assent, no acceptance of an alien report. Nor can it call on demonstration or, we are told it may at times act by this or, I method, at least there must be something patent to it in virtue of its own nature. In actual fact reason tells us that all its knowledge is thus inherent to it, for there is no means by which to distinguish between the spontaneous knowledge and the other. But, in any case, some knowledge, it is conceded, is inherent to it. Whence are we to understand the certainty of this knowledge to come to it or how do its objects carry the conviction of their reality?

Consider sense-knowledge: its objects seem most patently certified, yet the doubt returns whether the apparent reality may not lie in the states of the percipient rather than in the material before him; the decision demands intelligence or reasoning. Besides, even granting that what the senses grasp is really contained in the objects, none the less what is thus known by the senses is an image: sense can never grasp the thing itself; this remains for ever outside.

Now, if the Intellectual-Principle in its act- that is in knowing the intellectual- is to know these its objects as alien, we have to explain how it makes contact with them: obviously it might never come upon them, and so might never know them; or it might know them only upon the meeting: its knowing, at that, would not be an enduring condition. If we are told that the Intellectual-Principle and the Intellectual Objects are linked in a standing unity, we demand the description of this unity.

Next, the intellections would be impressions, that is to say not native act but violence from without: now how is such impressing possible and what shape could the impressions bear?

Intellection, again, becomes at this a mere handling of the external, exactly like sense-perception. What then distinguishes it unless that it deals with objects of less extension? And what certitude can it have that its knowledge is true? Or what enables it to pronounce that the object is good, beautiful, or just, when each of these ideas is to stand apart from itself? The very principles of judgement, by which it must be guided, would be excluded: with objects and canons alike outside it, so is truth.

Again; either the objects of the Intellectual-Principle are senseless and devoid of life and intellect or they are in possession of Intellect.

Now, if they are in possession of Intellect, that realm is a union of both and is Truth. This combined Intellectual realm will be the Primal Intellect: we have only then to examine how this reality, conjoint of Intellectual-Principle and its object, is to be understood, whether as combining self-united identity with yet duality and difference, or what other relation holds between them.

If on the contrary the objects of Intellectual-Principle are without intelligence and life, what are they? They cannot be premises, axioms or predicates: as predicates they would not have real existence; they would be affirmations linking separate entities, as when we affirm that justice is good though justice and good are distinct realities.

If we are told that they are self-standing entities- the distinct beings Justice and Good- then the Intellectual Realm will not be a unity nor be included in any unity: all is sundered individuality. Where, then, are they and what spatial distinction keeps them apart? How does the Intellectual-Principle come to meet with them as it travels round; what keeps each true to its character; what gives them enduring identity; what conceivable shape or character can they have? They are being presented to us as some collection of figures, in gold or some other material substance, the work of some unknown sculptor or graver: but at once the Intellectual-Principle which contemplates them becomes sense-perception; and there still remains the question how one of them comes to be Justice and another something else.

But the great argument is that if we are to allow that these objects of Intellection are in the strict sense outside the Intellectual-Principle, which, therefore, must see them as external, then inevitably it cannot possess the truth of them.

In all it looks upon, it sees falsely; for those objects must be the authentic things; yet it looks upon them without containing them and in such knowledge holds only their images; that is to say, not containing the authentic, adopting phantasms of the true, it holds the false; it never possesses reality. If it knows that it possesses the false, it must confess itself excluded from the truth; if it fails of this knowledge also, imagining itself to possess the truth which has eluded it, then the doubled falsity puts it the deeper into error.

It is thus, I suppose, that in sense-perception we have belief instead of truth; belief is our lief; we satisfy ourselves with something very different from the original which is the occasion of perception.

In fine, there would be on the hypothesis no truth in the Intellectual-Principle. But such an Intellectual-Principle would not be truth, nor truly an Intellectual-Principle. There would be no Intellectual-Principle at all : yet elsewhere truth cannot be.

(5) In short, whether you think that there is one genus of the Gods, one of dæmons, and in a similar manner of heroes, and souls essentially incorporeal; or whether you admit that these are severally many, you inquire what the difference of them is according to peculiarities. For if you apprehend that each of these is one [and the same genus] the whole arrangement of scientific theology is confounded. But if, as truth requires, you admit that they are genetically distinguished, and that there is not in them one common essential definition, but that those of them which are prior, are exempt from those that are inferior, it is not possible to discover their common boundaries. And even if this were possible, this very thing would destroy their peculiarities. In this way, therefore, the object of investigation cannot be found. He, however, he who directs his attention to the analogous sameness which exists in superior natures, as, for instance, in the many genera of the Gods, and again in dæmons and heroes, and, in the last place, in souls, will be able to define their peculiarities. Hence through this, it is demonstrated by us what the rectitude is of the present inquiry, and what its [accurate] distinction, and also in what manner it is impossible, and in what manner it is possible, for it to subsist.

(1) If, however, it be necessary, dismissing these particulars, to speak what appears to me to be the truth, you do not rightly infer “ that a knowledge of this mathematical science cannot be obtained, because there is much dissonance concerning it, or because Chæremon, or some other, has written against it .” For if this reason were admitted, all things will be incomprehensible. For all sciences have ten thousand controvertists, and the doubts with which they are attended are innumerable. As, therefore, we are accustomed to say in opposition to the contentious, that contraries in things that are true are naturally discordant, and that it is not falsities alone that are hostile to each other; thus, also, we say respecting this mathematical science, that it is indeed true; but that those who wander from the scope of it, being ignorant of the truth, contradict it. This, however happens not in this science alone, but likewise in all the sciences, which are imparted by the Gods to men.

(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.

(3) We assert, then, a plurality of Existents, but a plurality not fortuitous and therefore a plurality deriving from a unity.

But even admitting this derivation from a unity- a unity however not predicated of them in respect of their essential being- there is, surely, no reason why each of these Existents, distinct in character from every other, should not in itself stand as a separate genus.

Is, then, this unity external to the genera thus produced, this unity which is their source though it cannot be predicated of them in respect of their essence? it is indeed external; the One is beyond; it cannot, therefore, be included among the geneANSWER: it is the source, while they stand side by side as genera. Yet surely the one must somehow be included ? No: it is the Existents we are investigating, not that which is beyond Existence.

We pass on, then, to consider that which is included, and find to our surprise the cause included with the things it causes: it is surely strange that causes and effects should be brought into the same genus.

But if the cause is included with its effects only in the sense in which a genus is included with its subordinates, the subordinates being of a different order, so that it cannot be predicated of them whether as their genus or in any other relation, these subordinates are obviously themselves genera with subordinates of their own: you may, for example, be the cause of the operation of walking, but the walking is not subordinate to you in the relation of species to genus; and if walking had nothing prior to it as its genus, but had posteriors, then it would be a genus and rank among the Existents.

Perhaps, however, it must be utterly denied that unity is even the cause of other things; they should be considered rather as its parts or elements- if the terms may be allowed,- their totality constituting a single entity which our thinking divides. All unity though it be, it goes by a wonderful power out into everything; it appears as many and becomes many when there is a motion; the fecundity of its nature causes the One to be no longer one, and we, displaying what we call its parts, consider them each as a unity and make them into "genera," unaware of our failure to see the whole at once. We display it, then, in parts, though, unable to restrain their natural tendency to coalesce, we bring these parts together again, resign them to the whole and allow them to become a unity, or rather to be a unity.

All this will become clearer in the light of further consideration- when, that is to say, we have ascertained the number of the genera; for thus we shall also discover their causes. It is not enough to deny; we must advance by dint of thought and comprehension. The way is clear:

(2) But are we really obliged to posit the existence of such genera?

Take Substance, for Substance must certainly be our starting-point: what are the grounds for regarding Substance as one single genus?

It has been remarked that Substance cannot be a single entity common to both the Intellectual and the Sensible worlds. We may add that such community would entail the existence of something prior to Intellectual and Sensible Substances alike, something distinct from both as predicated of both; and this prior would be neither body nor unembodied; for it were one or the other, body would be unembodied, or the unembodied would be the body.

This conclusion must not however prevent our seeking in the actual substance of the Sensible world an element held in common by Matter, by Form and by their Composite, all of which are designated as substances, though it is not maintained that they are Substance in an equal degree; Form is usually held to be Substance in a higher degree than Matter, and rightly so, in spite of those who would have Matter to be the more truly real.

There is further the distinction drawn between what are known as First and Second Substances. But what is their common basis, seeing that the First are the source from which the Second derive their right to be called substances?

But, in sum, it is impossible to define Substance: determine its property, and still you have not attained to its essence. Even the definition, "That which, numerically one and the same, is receptive of contraries," will hardly be applicable to all substances alike.
