(1) With respect to your inquiry, “ what the peculiarities are in each of the more excellent genera, by which they are separated from each other? ” if you understand by peculiarities the specific differences under the same genus, which are distinguished by opposite qualities, as the rational and irrational under animal; we by no means admit peculiarities of this kind, in things which neither have one common essence, nor an equal contradistinction, nor receive a composition from something common, which is indefinite, and defines the peculiarity. But if you apprehend the peculiarity to be, as in prior and secondary natures, differing in their whole essence and whole genus, a certain simple condition of being, definite in itself; in this case, your conception of peculiarities will be reasonable. For these peculiarities of things, which have an eternal subsistence, are simple, and entirely exempt. The inquiry, however, proceeds imperfectly. For it was necessary, in the first place, to inquire what the peculiarities are of the more excellent genera, according to essence; in the next place, what they are according to power; and thus afterwards, what they are according to energy.

(1) "Substance" means: "that which underlies all outward manifestations; the essence; the essential reality; the thing in itself," etc. "Substantial" means: "actually existing; being the essential element; being real," etc. "Reality" means: "the state of being real; true, enduring; valid; fixed; permanent; actual," etc.

(1) But neither must we admit that cause of the distinction of these genera which you subjoin, viz. “ that it is an arrangement with reference to different bodies; as, for instance, of Gods to etherial bodies, but of dæmons to aerial bodies, and of souls to such as are terrene .” For such an arrangement as this, which resembles that of Socrates to a tribe, when he is a senator, is unworthy of the divine genera, because all of them are essentially unrestrained and free. To which may be added, that it is dreadfully absurd to ascribe to bodies a principal power of giving a specific distinction to the first causes of themselves. For bodies are in servile subjection to these causes, and are ministrant to generation. And farther still, the genera of the more excellent natures are not in bodies, but the former externally rule over the latter. Hence they are not changed in conjunction with bodies. Again, they impart from themselves to bodies every such good as they are able to receive, but they themselves receive nothing from bodies; so that neither will they derive from them certain peculiarities.

(2) These, also, may now be divided according to the difference of commixture. For mundane vapours are mingled with dæmons, and are unstably borne along, contrary to the motion of the world. Genesiurgic compositions of pneumatic substances are mingled with heroes, about which substances, also, they are moved. The archons of the world remain invariably the same, exhibiting the mundane nature which they possess. But the archons of matter are full of material substances. And souls are filled with an abundance of stains and foreign spirits, together with which, when they become visible, each of these genera presents itself to the view.

(2) For if they were as the habits of bodies, or as material forms, or were in some other way corporeal-formed, it would, perhaps, be possible for them to be changed together with the differences of bodies. But if they are separate from bodies, and essentially preexist unmingled with them, what reasonable distinction, produced from bodies, can be transferred to them? To which also may be added, that this assertion of yours makes bodies to be more excellent than the divine genera, since the former afford a seat to superior causes, and insert in them peculiarities essentially. He, therefore, who coarranges allotments, distributions, and consociations of governors with the governed, will evidently assign a principal authority to more excellent natures. For, because the presiding powers are such [as we have shown them to be], on this account they have such an allotment, and give to it an essential specific distinction, but they are not assimilated to the nature of their receptacles.

(24) Now in definitions, difference is assumed, which, in the definition, occupies the place of sign. The faculty of laughing, accordingly, being added to the definition of man, makes the whole - a rational, mortal, terrestrial, walking, laughing animal. For the things added by way of difference to the definition are the signs of the properties of things; but do not show the nature of the things themselves. Now they say that the difference is the assigning of what is peculiar; and as that which has the difference differs from all the rest, that which belongs to it alone, and is predicated conversely of the thing, must in definitions be assumed by the first genus as principal and fundamental.

(32) Thereafter comes the completion of the series of transformations of the three nature potencies, since their purpose is attained.

(19) And so every Element qualifies [or acts] in its own Source [or Manner of Operation,] and one could do nothing without the other, neither could one have any Mobility without the other. For one generates the other, and they go all four out of one Original, and it is in its Birth but one only [Thing or] Substance as I have mentioned before at large about the Creation, concerning the Birth of the four Elements.

(27) Accordingly, while the definition is explanatory of the essence of the thing, it is incapable of accurately comprehending its nature. By means of the principal species, the definition makes an exposition of the essence, and almost has the essence in the quality.

(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.

(3) It is necessary, therefore, to admit a thing of this kind in partial souls. For such as is the life which the soul received, prior to its insertion in a human body, and such as the form which it readily exerted; such also is the organical body which it has suspended from itself, and such the consequent corresponding nature, which receives the more perfect life of the soul. But with respect to more excellent natures, and which, as wholes, comprehend the principle [of parts] in these, inferior are produced in superior natures; bodies, in incorporeal essences; things fabricated, in the fabricators; and, being circularly comprehended in, are directed and governed by, them. Hence, the circulations of the celestial bodies, being primarily inserted in the celestial circulations of the etherial soul, are perpetually inherent in them; and the souls of the worlds [ i. e. of the spheres], being extended to their intellect, are perfectly comprehended by it, and are primarily generated in it. Intellect, also, both that which is partial and that which is universal, is in a similar manner comprehended in the genera that are more excellent than intellect. Since, therefore, second are always converted to first natures, and superior are the leaders of inferior essences, as being the paradigms of them, hence essence and form accede to subordinate from superior natures, and things posterior are primarily produced in such as are more excellent; so that order and measure are derived from primary to secondary beings, and the latter possess that which they are from the former. But the contrary must not be admitted, viz. that peculiarities emanate from things less excellent to the natures which precede them.

(2) But, as your question now stands, with respect to the peculiarities by which these genera are separated, you alone speak of the peculiarities of energies. Hence you inquire concerning the difference in the last things pertaining to them; but you leave uninvestigated such things as are first, and most honourable in them, and which are the elements of their difference. In the same place, also, something is added concerning “ efficacious and passive motions ,” which is a division by no means adapted to the difference of the more excellent genera. For the contrariety of action and passion is not inherent in any one of them; but their energies are unrestrained, immutable, and without habitude to their opposites. Hence, neither must we admit in them motions of such a kind as arise from action and passion. For neither do we admit in the soul a self-motion, which consists of the mover and that which is moved; but we conceive that it is a certain simple essential motion, subsisting from itself, and not possessing a habitude to another thing, and exempt from acting on, and suffering from, itself. Who, therefore, can endure that the peculiarities of the genera superior to the soul, should be distinguished according to active or passive motions?

(9) Accordingly we must first take the genus, in which are the points that are nearest those above; and after this the next difference. And the succession of differences, when cut and divided, completes the "What it is." There is no necessity for expressing all the differences of each thing, but those which form the species.

(3) That also which is added by you, “ or of accidents ,” is foreign from these genera. For in composites, and things which exist together with, or in others, or are comprehended by others, some things are conceived to be precedaneous, but others consequent; and some as essences, but others, as afterwards acceding to essences. For there is a certain coarrangement of them, and incongruity and interval intervenes. But, in the more excellent genera, all things must be conceived in τῳ ειναι , i. e. in merely existing ; and wholes have a precedaneous subsistence, are separate by themselves, and have not their hypostasis from, or in others; so that there is not any thing in them which is accidental. Hence the peculiarity of them is not characterized from accidents.

(1) This is the meaning of that saying of St. Paul: “When that which is perfect is come” (that is, when it is known), “then that which is in part” (to wit, creature-nature, qualities, the I, the Self, the Mine) will be despised and counted for nought. So long as we think much of these things, cleave to them with love, joy, pleasure or desire, so long remaineth the Perfect unknown to us. But it might further be said, “Thou sayest, beside the Perfect there is no Substance, yet sayest again that somewhat floweth out from it: now is not that which hath flowed out from it, something beside it.” Answer: This is why we say, beside it, or without it, there is no true Substance. That which hath flowed forth from it, is no true Substance, and hath no Substance except in the Perfect, but is an accident, or a brightness, or a visible appearance, which is no Substance, and hath no Substance except in the fire whence the brightness flowed forth, such as the sun or a candle.

(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.

(3) Of things stated, some are stated without connection; as, for example, "man" and "runs," and whatever does not complete a sentence, which is either true or false. And of things stated in connection, some point out "essence," some "quality," some "quantity," some "relation,'' some "where," some "when," some "position," some "possession," some "action," some "suffering," which we call the elements of material things after the first principles. For these are capable of being contemplated by reason.

(22) For each of the species is either an essence; as when we say, Some substances are corporeal and some incorporeal; or how much, or what relation, or where, or when, or doing, or suffering.

(1) Leaving, therefore, these particulars, you wish in the next place that I would unfold to you “ What the Egyptians conceive the first cause to be; whether intellect, or above intellect; whether alone, or subsisting with some other or others; whether incorporeal, of corporeal; and whether it is the same with the Demiurgus, or is prior to the Demiurgus? Likewise, whether all things are from one principle, or from many principles; whether they have a knowledge of matter, or of primary corporeal qualities; and whether they admit matter to be unbegotten, or to be generated? ” I, therefore, will in the first place relate to you the cause why in the books of the ancient writers of sacred concerns many and various opinions concerning these things are circulated, and also why among those that are still living, and are renowned for their wisdom, the opinion on this subject is not simple and one. I say then, that as there are many essences, and these differing from each other, the all-various multitude of the principles of these, and which have different orders, were delivered by different ancient priests. As Seleucus narrates, therefore, Hermes described the principles that rank as wholes in two myriads of books; or, as we are informed by Manetho , he perfectly unfolded these principles in three myriads six thousand five hundred and twenty five volumes. But different ancient writers differently explained the partial principles of essences. It is necessary, however, by investigation to discover the truth about all these principles, and concisely to unfold it to you as much as possible. And, in the first place, hear concerning that which is the first subject of your inquiry.

(2) But it reasonably follows, according to continuity of alliance, that the medium which begins from the most excellent natures, should proceed to such as are less excellent; but that the medium which primarily produces a contact with the last of things, should also in a certain respect communicate with the natures that transcend it. From these media, also, the completion may be seen of the first and last genera, and this entirely connascent, in a similar manner, in existence, in power, and in energy. As we have, therefore, in these two ways, perfectly completed the division of the four genera, we shall deem it sufficient in the others, to exhibit the extreme peculiarities alone, for the sake of conciseness, and because what remains, i. e. the comprehension of the media, is in a certain respect evident. But the media themselves, as being known from the extremes, we shall omit; making a definition of the extremes in the shortest way, as follows.
