(4) But this science, this Dialectic essential to all the three classes alike, what, in sum, is it?

It is the Method, or Discipline, that brings with it the power of pronouncing with final truth upon the nature and relation of things- what each is, how it differs from others, what common quality all have, to what Kind each belongs and in what rank each stands in its Kind and whether its Being is Real-Being, and how many Beings there are, and how many non-Beings to be distinguished from Beings.

Dialectic treats also of the Good and the not-Good, and of the particulars that fall under each, and of what is the Eternal and what the not Eternal- and of these, it must be understood, not by seeming-knowledge but with authentic science.

All this accomplished, it gives up its touring of the realm of sense and settles down in the Intellectual Kosmos and there plies its own peculiar Act: it has abandoned all the realm of deceit and falsity, and pastures the Soul in the "Meadows of Truth": it employs the Platonic division to the discernment of the Ideal-Forms, of the Authentic-Existence and of the First-Kinds : it establishes, in the light of Intellection, the unity there is in all that issues from these Firsts, until it has traversed the entire Intellectual Realm: then, resolving the unity into the particulars once more, it returns to the point from which it starts.

Now rests: instructed and satisfied as to the Being in that sphere, it is no longer busy about many things: it has arrived at Unity and it contemplates: it leaves to another science all that coil of premisses and conclusions called the art of reasoning, much as it leaves the art of writing: some of the matter of logic, no doubt, it considers necessary- to clear the ground- but it makes itself the judge, here as in everything else; where it sees use, it uses; anything it finds superfluous, it leaves to whatever department of learning or practice may turn that matter to account.

(511) I understand, he said, that you are speaking of the province of geometry and the sister arts. And when I speak of the other division of the intelligible, you will understand me to speak of that other sort of knowledge which reason herself attains by the power of dialectic, using the hypotheses not as first principles, but only as hypotheses—that is to say, as steps and points of departure into a world which is above hypotheses, in order that she may soar beyond them to the first principle of the whole; and clinging to this and then to that which depends on this, by successive steps she descends again without the aid of any sensible object, from ideas, through ideas, and in ideas she ends. I understand you, he replied; not perfectly, for you seem to me to be describing a task which is really tremendous; but, at any rate, I understand you to say that knowledge and being, which the science of dialectic contemplates, are clearer than the notions of the arts, as they are termed, which proceed from hypotheses only: these are also contemplated by the understanding, and not by the senses: yet, because

(6) Philosophy has other provinces, but Dialectic is its precious part: in its study of the laws of the universe, Philosophy draws on Dialectic much as other studies and crafts use Arithmetic, though, of course, the alliance between Philosophy and Dialectic is closer.

And in Morals, too, Philosophy uses Dialectic: by Dialectic it comes to contemplation, though it originates of itself the moral state or rather the discipline from which the moral state develops.

Our reasoning faculties employ the data of Dialectic almost as their proper possession for they are mainly concerned about Matter .

And while the other virtues bring the reason to bear upon particular experiences and acts, the virtue of Wisdom is a certain super-reasoning much closer to the Universal; for it deals with correspondence and sequence, the choice of time for action and inaction, the adoption of this course, the rejection of that other: Wisdom and Dialectic have the task of presenting all things as Universals and stripped of matter for treatment by the Understanding.

But can these inferior kinds of virtue exist without Dialectic and philosophy?

Yes- but imperfectly, inadequately.

And is it possible to be a Sage, Master in Dialectic, without these lower virtues?

It would not happen: the lower will spring either before or together with the higher. And it is likely that everyone normally possesses the natural virtues from which, when Wisdom steps in, the perfected virtue develops. After the natural virtues, then, Wisdom and, so the perfecting of the moral nature. Once the natural virtues exist, both orders, the natural and the higher, ripen side by side to their final excellence: or as the one advances it carries forward the other towards perfection.

But, ever, the natural virtue is imperfect in vision and in strength- and to both orders of virtue the essential matter is from what principles we derive them.

(1) We shall, therefore, deliver to you the peculiar dogmas of the Assyrians; and also clearly develop to you our own opinions; collecting some things from the infinite writings of the ancients, but others from those particulars which were comprehended by the ancients in one treatise, and pertain to the whole knowledge of divine natures. If also you should propose any philosophic inquiry, we shall discuss it for you, according to the ancient pillars of Hermes, which Plato and Pythagoras knew before, and from thence constituted their philosophy. But such things as exhibit foreign inquiries, or which are contradictory and contentious, we shall assist mildly and aptly, or we shall demonstrate their absurdity. Such, likewise, as proceed conformably to common conceptions, we shall endeavour to discuss in a way perfectly known and clear. And things, indeed, which require the experience of divine operations to an accurate knowledge of them, we shall explain, as far as this is possible to be effected by words alone; but such as are full of intellectual theory, we shall develop with a view to the purification of the soul.

(8) (At this point, it may be proper for me to state that we make a distinction between Religion and Theology--between Philosophy and Metaphysics. Religion, to us, means that intuitional realization of the existence of THE ALL, and one's relationship to it; while Theology means the attempts of men to ascribe personality, qualities, and characteristics to it; their theories regarding its affairs, will, desires, plans, and designs, and their assumption of the office of '' middle-men'' between THE ALL and the people. Philosophy, to us, means the inquiry after knowledge of things knowable and thinkable; while Metaphysics means the attempt to carry the inquiry over and beyond the boundaries and into regions unknowable and unthinkable, and with the same tendency as that of Theology. And consequently, both Religion and Philosophy mean to us things having roots in Reality, while Theology and Metaphysics seem like broken reeds, rooted in the quicksands of ignorance, and affording naught but the most insecure support for the mind or soul of Man. we do not insist upon our students accepting these definitions--we mention them merely to show our position. At any rate, you shall hear very little about Theology and Metaphysics in these lessons.)

(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.

(2) ... For in any one science the reduction of the total of knowledge into its separate propositions does not shatter its unity, chipping it into unrelated fragments; in each distinct item is talent the entire body of the science, an integral thing in its highest Principle and its last detail: and similarly a man must so discipline himself that the first Principles of his Being are also his completions, are totals, that all be pointed towards the loftiest phase of the Nature: when a man has become this unity in the best, he is in that other realm; for it is by this highest within himself, made his own, that he holds to the Supreme.

At no point did the All-Soul come into Being: it never arrived, for it never knew place; what happens is that body, neighbouring with it, participates in it: hence Plato does not place Soul in body but body in Soul. The others, the secondary Souls, have a point of departure- they come from the All-Soul- and they have a Place into which to descend and in which to change to and fro, a place, therefore, from which to ascend: but this All-Soul is for ever Above, resting in that Being in which it holds its existence as Soul and followed, as next, by the Universe or, at least, by all beneath the sun.

The partial Soul is illuminated by moving towards the Soul above it; for on that path it meets Authentic Existence. Movement towards the lower is towards non-Being: and this is the step it takes when it is set on self; for by willing towards itself it produces its lower, an image of itself- a non-Being- and so is wandering, as it were, into the void, stripping itself of its own determined form. And this image, this undetermined thing, is blank darkness, for it is utterly without reason, untouched by the Intellectual-Principle, far removed from Authentic Being.

As long as it remains at the mid-stage it is in its own peculiar region; but when, by a sort of inferior orientation, it looks downward, it shapes that lower image and flings itself joyfully thither.

(1) The soul: what dubious questions concerning it admit of solution, or where we must abide our doubt- with, at least, the gain of recognizing the problem that confronts us- this is matter well worth attention. On what subject can we more reasonably expend the time required by minute discussion and investigation? Apart from much else, it is enough that such an enquiry illuminates two grave questions: of what sphere the soul is the principle, and whence the soul itself springs. Moreover, we will be only obeying the ordinance of the God who bade us know ourselves.

Our general instinct to seek and learn, our longing to possess ourselves of whatsoever is lovely in the vision will, in all reason, set us enquiring into the nature of the instrument with which we search.

Now even in the universal Intellect there was duality, so that we would expect differences of condition in things of part: how some things rather than others come to be receptacles of the divine beings will need to be examined; but all this we may leave aside until we are considering the mode in which soul comes to occupy body. For the moment we return to our argument against those who maintain our souls to be offshoots from the soul of the universe .

Our opponents will probably deny the validity of our arguments against the theory that the human soul is a mere segment of the All-Soul- the considerations, namely, that it is of identical scope, and that it is intellective in the same degree, supposing them, even, to admit that equality of intellection.

They will object that parts must necessarily fall under one ideal-form with their wholes. And they will adduce Plato as expressing their view where, in demonstrating that the All is ensouled, he says "As our body is a portion of the body of the All, so our soul is a portion of the soul of the All." It is admitted on clear evidence that we are borne along by the Circuit of the All; we will be told that- taking character and destiny from it, strictly inbound with it- we must derive our souls, also, from what thus bears us up, and that as within ourselves every part absorbs from our soul so, analogically, we, standing as parts to the universe, absorb from the Soul of the All as parts of it. They will urge also that the dictum "The collective soul cares for all the unensouled," carries the same implication and could be uttered only in the belief that nothing whatever of later origin stands outside the soul of the universe, the only soul there can be there to concern itself with the unensouled.

(47) Though the modern world may know a million secrets, the ancient world knew one--and that one was greater than the million; for the million secrets breed death, disaster, sorrow, selfishness, lust, and avarice, but the one secret confers life, light, and truth. The time will come when the secret wisdom shall again be the dominating religious and philosophical urge of the world. The day is at hand when the doom of dogma shall be sounded. The great theological Tower of Babel, with its confusion of tongues, was built of bricks of mud and the mortar of slime. Out of the cold ashes of lifeless creeds, however, shall rise phœnixlike the ancient Mysteries. No other institution has so completely satisfied the religious aspirations of humanity, for since the destruction of the Mysteries there never has been a religious code to which Plato could have subscribed. The unfolding of man's spiritual nature is as much an exact science as astronomy, medicine or jurisprudence. To accomplish this end religions were primarily established; and out of religion have come science, philosophy, and logic as methods whereby this divine purpose might be realized.

(5) Man, thus, must be some Reason-Principle other than soul. But why should he not be some conjoint- a soul in a certain Reason-Principle- the Reason-Principle being, as it were, a definite activity which however could not exist without that which acts?

This is the case with the Reason-Principles in seed which are neither soulless nor entirely soul. For these productive principles cannot be devoid of soul and there is nothing surprising in such essences being Reason-Principles.

But these principles producing other forms than man, of what phase of soul are they activities? Of the vegetal soul? Rather of that which produces animal life, a brighter soul and therefore one more intensely living.

The soul of that order, the soul that has entered into Matter of that order, is man by having, apart from body, a certain disposition; within body it shapes all to its own fashion, producing another form of Man, man reduced to what body admits, just as an artist may make a reduced image of that again.

It is soul, then, that holds the pattern and Reason-Principles of Man, the natural tendencies, the dispositions and powers- all feeble since this is not the Primal Man- and it contains also the Ideal-Forms of other senses, Forms which themselves are senses, bright to all seeming but images, and dim in comparison with those of the earlier order.

The higher Man, above this sphere, rises from the more godlike soul, a soul possessed of a nobler humanity and brighter perceptions. This must be the Man of Plato's definition , where the addition "Soul as using body" marks the distinction between the soul which uses body directly and the soul, poised above, which touches body only through that intermediary.

The Man of the realm of birth has sense-perception: the higher soul enters to bestow a brighter life, or rather does not so much enter as simply impart itself; for soul does not leave the Intellectual but, maintaining that contact, holds the lower life as pendant from it, blending with it by the natural link of Reason-Principle to Reason-Principle: and man, the dimmer, brightens under that illumination.

(531) regard the skilled mathematician as a dialectician? Assuredly not, he said; I have hardly ever known a mathematician who was capable of reasoning. But do you imagine that men who are unable to give and take a reason will have the knowledge which we require of them? Neither can this be supposed. And so, Glaucon, I said, we have at last arrived at the hymn of dialectic. This is that strain which is of the intellect only, but which the faculty of sight will nevertheless be found to imitate; for sight, as you may remember, was imagined by us after a while to behold the real animals and stars, and last of all the sun himself. And so with dialectic; when a person starts on the discovery of the absolute by the light of reason only, and without any assistance of sense, and perseveres until by pure intelligence he arrives at the perception of the absolute good, he at last finds himself at the end of the intellectual world, as in the case of sight at the end of the visible. Exactly, he said. Then this is the progress which you call dialectic? True. But the release of the prisoners from chains, and their translation from the shadows to the images and to the light, and the ascent from the underground den to the sun, while in his presence they are vainly trying to look on animals and plants and the light of the sun, but are able to perceive

(1) Since it is usual with all men of sound understandings, to call on divinity, when entering on any philosophic discussion, it is certainly much more appropriate to do this in the consideration of that philosophy which justly receives its denomination from the divine Pythagoras. For as it derives its origin from the Gods, it cannot be apprehended without their inspiring aid. To which we may also add, that the beauty and magnitude of it so greatly surpasses human power, that it is impossible to survey it by a sudden view; but then alone can any one gradually collect some portion of this philosophy, when, the Gods being his leaders, he quietly approaches to it. On all these accounts, therefore, having invoked the Gods as our leaders, and converting both ourselves and our discussion to them, we shall acquiesce in whatever they may command us to do.

We shall not, however, make any apology for this sect having been neglected for a long time, nor for its being concealed by foreign disciplines, and certain arcane symbols, nor for having been obscured by false and spurious writings, nor for many other such-like difficulties by which it has been impeded. For the will of the Gods is sufficient for us, in conjunction with which it is possible to sustain things still more arduous than these. But after the Gods, we shall unite ourselves as to a leader, to the prince and father of this divine philosophy; of whose origin and country we must rise a little higher in our investigation.

(26) The sect of the Academic philosophers instituted by Plato (427-347 B.C.) was divided into three major parts--the old, the middle, and the new Academy. Among the old Academics were Speusippus, Zenocrates, Poleman, Crates, and Crantor. Arcesilaus instituted the middle Academy and Carneades founded the new. Chief among the masters of Plato was Socrates. Plato traveled widely and was initiated by the Egyptians into the profundities of Hermetic philosophy. He also derived much from the doctrines of the Pythagoreans. Cicero describes the threefold constitution of Platonic philosophy as comprising ethics, physics, and dialectics. Plato defined good as threefold in character: good in the soul, expressed through the virtues; good in the body, expressed through the symmetry and endurance of the parts; and good in the external world, expressed through social position and companionship. In The Book of Speusippus on Platonic Definitions, that great Platonist thus defines God: "A being that lives immortally by means of Himself alone, sufficing for His own blessedness, the eternal Essence, cause of His own goodness. According to Plato, the One is the term most suitable for defining the Absolute, since the whole precedes the parts and diversity is dependent on unity, but unity not on diversity. The One, moreover, is before being, for to be is an attribute or condition of the One.

(2) Enquiring, then, of Plato as to our own soul, we find ourselves forced to enquire into the nature of soul in general- to discover what there can be in its character to bring it into partnership with body, and, again, what this kosmos must be in which, willing unwilling or in any way at all, soul has its activity.

We have to face also the question as to whether the Creator has planned well or ill...... like our souls, which it may be, are such that governing their inferior, the body, they must sink deeper and deeper into it if they are to control it.

No doubt the individual body- though in all cases appropriately placed within the universe- is of itself in a state of dissolution, always on the way to its natural terminus, demanding much irksome forethought to save it from every kind of outside assailant, always gripped by need, requiring every help against constant difficulty: but the body inhabited by the World-Soul- complete, competent, self-sufficing, exposed to nothing contrary to its nature- this needs no more than a brief word of command, while the governing soul is undeviatingly what its nature makes it wish to be, and, amenable neither to loss nor to addition, knows neither desire nor distress.

This is how we come to read that our soul, entering into association with that complete soul and itself thus made perfect, walks the lofty ranges, administering the entire kosmos, and that as long as it does not secede and is neither inbound to body nor held in any sort of servitude, so long it tranquilly bears its part in the governance of the All, exactly like the world-soul itself; for in fact it suffers no hurt whatever by furnishing body with the power to existence, since not every form of care for the inferior need wrest the providing soul from its own sure standing in the highest.

The soul's care for the universe takes two forms: there is the supervising of the entire system, brought to order by deedless command in a kindly presidence, and there is that over the individual, implying direct action, the hand to the task, one might say, in immediate contact: in the second kind of care the agent absorbs much of the nature of its object.

Now in its comprehensive government of the heavenly system, the soul's method is that of an unbroken transcendence in its highest phases, with penetration by its lower power: at this, God can no longer be charged with lowering the All-Soul, which has not been deprived of its natural standing and from eternity possesses and will unchangeably possess that rank and habit which could never have been intruded upon it against the course of nature but must be its characteristic quality, neither failing ever nor ever beginning.

Where we read that the souls or stars stand to their bodily forms as the All to the material forms within it- for these starry bodies are declared to be members of the soul's circuit- we are given to understand that the star-souls also enjoy the blissful condition of transcendence and immunity that becomes them.

And so we might expect: commerce with the body is repudiated for two only reasons, as hindering the soul's intellective act and as filling with pleasure, desire, pain; but neither of these misfortunes can befall a soul which has never deeply penetrated into the body, is not a slave but a sovereign ruling a body of such an order as to have no need and no shortcoming and therefore to give ground for neither desire nor fear.

There is no reason why it should be expectant of evil with regard to such a body nor is there any such preoccupied concern, bringing about a veritable descent, as to withdraw it from its noblest and most blessed vision; it remains always intent upon the Supreme, and its governance of this universe is effected by a power not calling upon act.

(44) When the physical body of pagan thought collapsed, an attempt was made to resurrect the form by instilling new life into it by the unveiling of its mystical truths. This effort apparently was barren of results. Despite the antagonism, however, between pristine Christianity and Neo-Platonism many basic tenets of the latter were accepted by the former and woven into the fabric of Patristic philosophy. Briefly described, Neo-Platonism is a philosophic code which conceives every physical or concrete body of doctrine to be merely the shell of a spiritual verity which may be discovered through meditation and certain exercises of a mystic nature. In comparison to the esoteric spiritual truths which they contain, the corporeal bodies of religion and philosophy were considered relatively of little value. Likewise, no emphasis was placed upon the material sciences.

(5) But whence does this science derive its own initial laws?

The Intellectual-Principle furnishes standards, the most certain for any soul that is able to apply them. What else is necessary, Dialectic puts together for itself, combining and dividing, until it has reached perfect Intellection. "For," we read, "it is the purest of Intellection and Contemplative-Wisdom." And, being the noblest method and science that exists it must needs deal with Authentic-Existence, The Highest there is: as Contemplative-Wisdom it deals with Being, as Intellection with what transcends Being.

What, then, is Philosophy?

Philosophy is the supremely precious.

Is Dialectic, then, the same as Philosophy?

It is the precious part of Philosophy. We must not think of it as the mere tool of the metaphysician: Dialectic does not consist of bare theories and rules: it deals with verities; Existences are, as it were, Matter to it, or at least it proceeds methodically towards Existences, and possesses itself, at the one step, of the notions and of the realities.

Untruth and sophism it knows, not directly, not of its own nature, but merely as something produced outside itself, something which it recognises to be foreign to the verities laid up in itself; in the falsity presented to it, it perceives a clash with its own canon of truth. Dialectic, that is to say, has no knowledge of propositions- collections of words- but it knows the truth, and, in that knowledge, knows what the schools call their propositions: it knows above all, the operation of the soul, and, by virtue of this knowing, it knows, too, what is affirmed and what is denied, whether the denial is of what was asserted or of something else, and whether propositions agree or differ; all that is submitted to it, it attacks with the directness of sense-perception and it leaves petty precisions of process to what other science may care for such exercises.

(5) But what place is left for the particular souls, yours and mine and another's?

May we suppose the Soul to be appropriated on the lower ranges to some individual, but to belong on the higher to that other sphere?

At this there would be a Socrates as long as Socrates' soul remained in body; but Socrates ceases to exist, precisely on attainment of the highest.

Now nothing of Real Being is ever annulled.

In the Supreme, the Intellectual-Principles are not annulled, for in their differentiation there is no bodily partition, no passing of each separate phase into a distinct unity; every such phase remains in full possession of that identical being. It is exactly so with the souls.

By their succession they are linked to the several Intellectual-Principles, for they are the expression, the Logos, of the Intellectual-Principles, of which they are the unfolding; brevity has opened out to multiplicity; by that point of their being which least belongs to the partial order, they are attached each to its own Intellectual original: they have already chosen the way of division; but to the extreme they cannot go; thus they keep, at once, identification and difference; each soul is permanently a unity and yet all are, in their total, one being.

Thus the gist of the matter is established: one soul the source of all; those others, as a many founded in that one, are, on the analogy of the Intellectual-Principle, at once divided and undivided; that Soul which abides in the Supreme is the one expression or Logos of the Intellectual-Principle, and from it spring other Reason-Principles, partial but immaterial, exactly as in the differentiation of the Supreme.

(27) Platonic philosophy is based upon the postulation of three orders of being: that which moves unmoved, that which is self-moved, and that which is moved. That which is immovable but moves is anterior to that which is self-moved, which likewise is anterior to that which it moves. That in which motion is inherent cannot be separated from its motive power; it is therefore incapable of dissolution. Of such nature are the immortals. That which has motion imparted to it from another can be separated from the source of its an animating principle; it is therefore subject to dissolution. Of such nature are mortal beings. Superior to both the mortals and the immortals is that condition which continually moves yet itself is unmoved. To this constitution the power of abidance is inherent; it is therefore the Divine Permanence upon which all things are established. Being nobler even than self-motion, the unmoved Mover is the first of all dignities. The Platonic discipline was founded upon the theory that learning is really reminiscence, or the bringing into objectivity of knowledge formerly acquired by the soul in a previous state of existence. At the entrance of the Platonic school in the Academy were written the words: "Let none ignorant of geometry enter here."

(1) Hermes, the God who presides over language, was formerly very properly considered as common to all priests; and the power who presides over the true science concerning the Gods is one and the same in the whole of things. Hence our ancestors dedicated the inventions of their wisdom to this deity, inscribing all their own writings with the name of Hermes. If, therefore, we participate of a portion of this God, adapted and commensurate to our powers, you do well to propose your theological doubts to the priests, as friends, and to make these doubts known to them. I also very properly conceiving that the epistle sent to my disciple Anebo was written to me, shall give you a true answer to your inquiries. For it would not be becoming, that Pythagoras and Plato, Democritus and Eudoxus, and many other of the ancient Greeks, should have obtained appropriate instruction from the sacred scribes of their time, but that you who are our contemporary, and think conformably to those ancients, should be frustrated of your wish by those who are now living, and who are called common preceptors. I, therefore, thus betake myself to the present discussion; and do you, if you please, conceive that the same person to whom you sent the letter returns you an answer. Or, if it should seem fit to you, admit it to be me who discourses with you in writing, or some other prophet of the Egyptians, for this is of no consequence. Or, which I think is still better, dismiss the consideration whether the speaker is an inferior or a superior character, but direct your attention to what is said, so as readily to excite your mind to survey whether what is asserted is true or false.

(1) It is also said, that Pythagoras was the first who called himself a philosopher; this not being a new name, but previously instructing us in a useful manner in a thing appropriate to the name. For he said that the entrance of men into the present life, resembled the progression of a crowd to some public spectacle. For there men of every description assemble with different views; one hastening to sell his wares for the sake of money and gain; but another that he may acquire renown by exhibiting the strength of his body; and there is also a third class of men, and those the most liberal, who assemble for the sake of surveying the places, the beautiful works of art, the specimens of valor, and the literary productions which are usually exhibited on such occasions.

Thus also in the present life, men of all-various pursuits are collected together in one and the same place. For some are influenced by the desire of riches and luxury; others by the love of power and dominion; and others are possessed with an insane ambition for glory. But the most pure and unadulterated character, is that of the man who gives himself to the contemplation of the most beautiful things, and whom it is proper to call a philosopher. He adds, that the survey of all heaven, and of the stars that revolve in it, is indeed beautiful, when the order of them is considered. For they derive this beauty and order by the participation of the first and the intelligible essence.

But that first essence is the nature of number and reasons [i. e. productive principles,] which pervades through all things, and according to which all these [celestial bodies] are elegantly arranged, and fitly adorned. And wisdom indeed, truly so called, is a certain science which is conversant with the first beautiful objects, and these divine, undecaying, and possessing an invariable sameness of subsistence; by the participation of which other things also may be called beautiful. But philosophy is the appetition of a thing of this kind. The attention therefore to erudition is likewise beautiful, which Pythagoras extended, in order to effect the correction of mankind.
