Introduction to the Philosophy and Writings of Plato
Chapter 5
The next important Platonic dogma in order, is that doctrine concerning ideas, about which the reader will find so much said in the notes on the Parmenides, that but little remains to be added here. That little however is as follows: The divine Pythagoras, and all those who have legitimately received his doctrines, among whom Plato holds the most distinguished rank, asserted that there are many orders of beings, viz. intelligible, intellectual, dianoetic, physical, or in short, vital and corporeal essences. For the progression of things, the subjection which naturally subsists together with such progression, and the power of diversity in coordinate genera give subsistence to all the multitude of corporeal and incorporeal natures. They said, therefore, that there are three orders in the whole extent of beings; viz. the intelligible, the dianoetic, and the sensible; and that in each of these ideas subsist, characterized by the respective essential properties of the natures by which they are contained. And with respect to intelligible ideas, these they placed among divine natures, together with the producing, paradigmatic, and final causes of things in a consequent order. For if these three causes sometimes concur, and are united among themselves, (which Aristotle says is the case), without doubt this will not happen in the lowest works of nature, but in the first and most excellent causes of all things, which on account of their exuberant fecundity have a power generative of all things, and from their converting and rendering similar to themselves the natures which they have generated, are the paradigms, or exemplars of all things. But as these divine causes act for their own sake, and on account of their own goodness, do they not exhibit the final cause? Since therefore intelligible forms are of this kind, and are the leaders of so much good to wholes, they give completion to the divine orders, though they largely subsist about the intelligible order contained in the artificer of the universe. But dianoetic forms or ideas imitate the intellectual, which have a prior subsistence, render the order of soul similar to the intellectual order, and comprehend all things in a secondary degree.
These forms beheld in divine natures possess a fabricative power, but with us they are only gnostic, and no longer demiurgic, through the defluxion of our wings, or degradation of our intellectual powers. For, as Plato says in the Phaedrus, when the winged powers of the soul are perfect and plumed for flight, she dwells on high, and in conjunction with divine natures governs the world. In the Timaeus, he manifestly asserts that the demiurgus implanted these dianoetic forms in souls, in geometric, arithmetic, and harmonic proportions: but in his Republic (in the section of a line in the 6th book) he calls them images of intelligibles; and on this account does not for the most part disdain to denominate them intellectual, as being the exemplars of sensible natures. In the Phaedo he says that these are the causes to us of reminiscence; because disciplines are nothing else than reminiscences of middle dianoetic forms, from which the productive powers of nature being derived and inspired, give birth to all the mundane phenomena.
Plato however did not consider things definable, or in modern language abstract ideas, as the only universals, but prior to these he established those principles productive of science which essentially reside in the soul, as is evident from his Phaedrus and Phaedo. In the 10th book of the Republic too, he venerates those separate forms which subsist in a divine intellect. In the Phaedrus, he asserts that souls elevated to the supercelestial place, behold Justice herself, temperance herself, and science herself; and lastly in the Phaedo he evinces the immortality of the soul from the hypothesis of separate forms.
Syrianus[11], in his commentary on the 13th book of Aristotle's Metaphysics, shows in defense of Socrates, Plato, the Parmenideans, and Pythagoreans, that ideas were not introduced by these divine men according to the usual meaning of names, as was the opinion of Chrysippus, Archedemus, and many of the junior Stoics; for ideas are distinguished by many differences from things which are denominated from custom. Nor do they subsist, says he, together with intellect, in the same manner as those slender conceptions which are denominated universals abstracted from sensibles, according to the hypothesis of Longinus:[12] for if that which subsists is unsubstantial, it cannot be consubsistent with intellect.
[11] See my translation of Aristotle's Metaphysics, p. 347. If the reader conjoins what is said concerning ideas in the notes on that work, with the introduction and notes to the Parmenides in this, he will be in possession of nearly all that is to be found in the writings of the ancients on this subject.
[12] It appears from this passage of Syrianus that Longinus was the original inventor of the theory of abstract ideas; and that Mr. Locke was merely the restorer of it. -----------------
Nor are ideas according to these men notions, as Cleanthes afterwards asserted them to be. Nor is idea definite reason, nor material form; for these subsist in composition and division, and verge to matter. But ideas are perfect, simple, immaterial, and impartible natures. And what wonder is there, says Syrianus, if we should separate things which are so much distant from each other? Since neither do we imitate in this particular Plutarch, Atticus, and Democritus, who, because universal reasons perpetually subsist in the essence of the soul, were of opinion that these reasons are ideas: for though they separate them from the universal in sensible natures, yet it is not proper to conjoin in one and the same the reason of soul, and an intellect such as ours, with paradigmatic and immaterial forms, and demiurgic intellections. But as the divine Plato says, it is the province of our soul to collect things into one by a reasoning process, and to possess a reminiscence of those transcendent spectacles, which we once beheld when governing the universe in conjunction with divinity. Boethus,[13] the peripatetic too, with whom it is proper to join Cornutus; thought that ideas are the same with universals in sensible natures. However, whether these universals are prior to particulars, they are not prior in such a manner as to be denudated from the habitude which they possess with respect to them, nor do they subsist as the causes of particulars; both which are the prerogatives of ideas; or whether they are posterior to particulars, as many are accustomed to call them, how can things of posterior origin, which have no essential subsistence, but are nothing more than slender conceptions, sustain the dignity of fabricative ideas?
[13] This was a Greek philosopher, who is often cited by Simplicius in his Commentary on the Predicaments, and must not therefore be confounded with Boetius, the roman senator and philosopher. -------------------
In what manner then, says Syrianus, do ideas subsist according to the contemplative lovers of truth? We reply, intelligibly and tetradically ([Greek: noeros kai tetradikos]), in animal itself ([Greek: en to antozoo]), or the extremity of the intelligible order; but intellectually and decadically ([Greek: noeros kai dekadikos]), in the intellect of the artificer of the universe; for, according to the Pythagoric Hymn, "Divine number proceeds from the retreats of the undecaying monad, till it arrives at the divine tetrad which produced the mother of all things, the universal recipient, venerable, circularly investing all things with bound, immovable and unwearied, and which is denominated the sacred decad, both by the immortal gods and earth-born men."
[Greek: Proeisi gar o Theios arithmos, os phesin o Pythagoreios eis auton umnos, Monados ek keuthmonos akeralou esti'an iketai Tetrada epi zatheen, he de teke metera panton, Pandechea, presbeiran, oron peri pasi titheiran, Atropon, akamatou, dekada kleiousi min agnen, Athanatoi to theoi kai gegeneeis anthropoi.]
And such is the mode of their subsistence according to Orpheus, Pythagoras and Plato. Or if it be requisite to speak in more familiar language, an intellect sufficient to itself, and which is a most perfect cause, presides over the wholes of the universe, and through these governs all its parts; but at the same time that it fabricates all mundane natures, and benefits them by its providential energies, it preserves its own most divine and immaculate purity; and while it illuminates all things, is not mingled with the natures which it illuminates. This intellect, therefore, comprehending in the depths of its essence an ideal world, replete with all various forms, excludes privation of cause and casual subsistence, from its energy. But as it imparts every good and all possible beauty to its fabrications, it converts the universe to itself, and renders it similar to its own omniform nature. Its energy, too, is such as its intellection; but it understands all things, since it is most perfect. Hence there is not any thing which ranks among true beings, that is not comprehended in the essence of intellect; but it always establishes in itself ideas, which are not different from itself and its essence, but give completion to it, and introduce to the whole of things, a cause which is at the same time productive, paradigmatic, and final. For it energizes as intellect, and the ideas which it contains are paradigmatic, as being forms; and they energize from themselves, and according to their own exuberant goodness. And such are the Platonic dogmas concerning ideas, which sophistry and ignorance may indeed oppose, but will never be able to confute.
From this intelligible world, replete with omniform ideas, this sensible world, according to Plato, perpetually flows, depending on its artificer intellect, in the same manner as shadow on its forming substance. For as a deity of an intellectual characteristic is its fabricator, and both the essence and energy of intellect are established in eternity the sensible universe, which is the effect or production of such an energy, must be consubsistent with its cause, or in other words, must be a perpetual emanation from it. This will be evident from considering that every thing which is generated, is either generated by art or by nature, or according to power. It is necessary, therefore, that every thing operating according to nature or art should be prior to the things produced; but that things operating according to power should have their productions coexistent with themselves; just as the sun produces light coexistent with itself; fire, heat; and snow, coldness. If therefore the artificer of the universe produced it by art, he would not cause it simply to be, but to be in some particular manner; for all art produces form. Whence therefore does the world derive its being? If he produced it from nature, since that which makes by nature imparts something of itself to its productions, and the maker of the world is incorporeal, it would be necessary that the world, the offspring of such an energy, should be incorporeal. It remains therefore, that the demiurgus produced the universe by power alone; but every thing generated by power subsists together with the cause containing this power: and hence production of this kind cannot be destroyed unless the producing cause is deprived of power. The divine intellect therefore that produced the sensible universe caused it to be coexistent with himself.
This world thus depending on its divine artificer, who is himself an intelligible world replete with the archetypal ideas of all things, considered according to its corporeal nature, is perpetually flowing, and perpetually advancing to being (en to gignesthai), and compared with its paradigm, has no stability or reality of being. However, considered as animated by a divine soul, and as receiving the illuminations of all the supermundane gods, and being itself the receptacle of divinities from whom bodies are suspended, it is said by Plato in the Timaeus to be a blessed god. The great body of this world too, which subsists in a perpetual dispersion of temporal extension, may be properly called a whole with a total subsistence, on account of the perpetuity of its duration, though this is nothing more than a flowing eternity. And hence Plato calls it a whole of wholes; by the other wholes which are comprehended in its meaning, the celestial spheres, the sphere of fire, the whole of air considered as one great orb; the whole earth, and the whole sea. These spheres, which are called by Platonic writers parts with a total subsistence, are considered by Plato as aggoregately perpetual. For if the body of this world is perpetual, this also must be the case with its larger parts, on account of their exquisite alliance to it, and in order that wholes with a partial subsistence, such as all individuals, may rank in the last gradation of things.
As the world too, considered as one great comprehending whole, is called by Plato a divine animal, so likewise every whole which it contains is a world, possessing in the first place, a self-perfect unity; proceeding from the ineffable, by which it becomes a god; in the second place, a divine intellect; in the third place, a divine soul; and in the last place, a deified body. Hence each of these wholes is the producing cause of all the multitude which it contains, and on this account is said to be a whole prior to parts; because, considered as possessing an eternal form which holds all its parts together, and gives to the whole perpetuity of subsistence, it is not indigent of such parts to the perfection of its being. That these wholes which rank thus high in the universe are animated, must follow by a geometrical necessity. For, as Theophrastus well observes, wholes would possess less authority than parts, and things eternal than such as are corruptible, if deprived of the possession of soul.
And now having with venturous, yet unpresuming wing, ascended to the ineffable principle of things, and standing with every eye closed in the vestibules of the adytum, found that we could announce nothing concerning him, but only indicate our doubts and disappointment, and having thence descended to his occult and most venerable progeny, and passing through the luminous world of ideas, holding fast by the golden chain of deity, terminated our downward flight in the material universe, and its undecaying wholes, let us stop awhile and contemplate the sublimity and magnificence of the scene which this journey presents to our view. Here then we see the vast empire of deity, an empire terminated upwards by a principle so ineffable that all language is subverted about it, and downwards, by the vast body of the world. Immediately subsisting after this immense unknown we in the next place behold a mighty all- comprehending one, which as being next to that which is in every respect incomprehensible, possesses much of the ineffable and unknown. From this principle of principles, in which all things casually subsist absorbed in superessential light and involved in unfathomable depths, we view a beauteous progeny of principles, all largely partaking of the ineffable, all stamped with the occult characters of deity, all possessing an over-flowing fullness of good. From these dazzling summits, these ineffable blossoms, these divine propagations, we next see being, life, intellect, soul, nature and body depending; monads suspended from unities, deified natures proceeding from deities. Each of these monads too, is the leader of a series which extends from itself to the last of things, and which while it proceeds from, at the same time abides in, and returns to its leader. And all these principles and all their progeny are finally centred, and rooted by their summits in the first great all- comprehending one. Thus all beings proceed from, and are comprehended in the first being; all intellects emanate from one first intellect; all souls from one first soul; all natures blossom from one first nature; and all bodies proceed from the vital and luminous body of the world. And lastly, all these great monads are comprehended in the first one, from which both they and all their depending series are unfolded into light. Hence this first one is truly the unity of unities, the monad of monads, the principle of principles, the God of gods, one and all things, and yet one prior to all.
Such, according to Plato, are the flights of the true philosopher, such the August and magnificent scene which presents itself to his view. By ascending these luminous heights, the spontaneous tendencies of the soul to deity alone find the adequate object of their desire; investigation here alone finally reposes, doubt expires in certainty, and knowledge loses itself in the ineffable.
And here perhaps some grave objector, whose little soul is indeed acute, but sees nothing with a vision healthy and sound, will say that all this is very magnificent, but that it is soaring too high for man; that it is merely the effect of spiritual pride; that no truths, either in morality or theology, are of any importance which are not adapted to the level of the meanest capacity; and that all that it is necessary for man to know concerning either God or himself is so plain, that he that runs may read. In answer to such like cant, for it is nothing more,--a cant produced by the most profound ignorance, and frequently attended with the most deplorable envy, I ask, is then the Delphic precept, KNOW THYSELF, a trivial mandate? Can this be accomplished by every man? Or can any one properly know himself without knowing the rank he holds in the scale of being? And can this be effected without knowing what are the natures which he surpasses, and what those are by which he is surpassed? And can he know this without knowing as much of those natures as it is possible for him to know? And will the objector be hardy enough to say that every man is equal to this arduous task? That he who rushes from the forge, or the mines, with a soul distorted, crushed and bruised by base mechanical arts, and madly presumes to teach theology to a deluded audience, is master of this sublime, this most important science? For my own part I know of no truths which are thus obvious, thus accessible to every man, but axioms, those self-evident principles of science which are conspicuous by their own light, which are the spontaneous unperverted conceptions of the soul, and to which he who does not assent deserves, as Aristotle justly remarks, either pity or correction. In short, if this is to be the criterion of all moral and theological knowledge, that it must be immediately obvious to every man, that it is to be apprehended by the most careless inspection, what occasion is there for seminaries of learning? Education is ridiculous, the toil of investigation is idle. Let us at once confine Wisdom in the dungeons of Folly, recall Ignorance from her barbarous wilds, and close the gates of Science with everlasting bars.
Having thus taken a general survey of the great world, and descended from the intelligible to the sensible universe, let us still, adhering to that golden chain which is bound round the summit of Olympus, and from which all things are suspended, descend to the microcosm man. For man comprehends in himself partially everything which the world contains divinely and totally. Hence, according to Pluto, he is endued with an intellect subsisting in energy, and a rational soul proceeding from the same father and vivific goddess as were the causes of the intellect and soul of the universe. He has likewise an ethereal vehicle analogous to the heavens, and a terrestrial body, composed from the four elements, and with which also it is coordinate.
With respect to his rational part, for in this the essence of man consists, we have already shown that it is of a self-motive nature, and that it subsists between intellect, which is immovable both in essence and energy, and nature, which both moves and is moved. In consequence of this middle subsistence, the mundane soul, from which all partial souls are derived, is said by Plato in the Timaeus, to be a medium between that which is indivisible and that which is divisible about bodies, i.e. the mundane soul is a medium between the mundane intellect, and the whole of that corporeal life which the world participates. In like manner, the human soul is a medium between a daemoniacal intellect proximately, established above our essence, which it also elevates and perfects, and that corporeal life which is distributed about our body, and which is the cause of its generation, nutrition and increase. This daemoniacal intellect is called by Plato, in the Phaedrus, theoretic and, the governor of the soul. The highest part therefore of the human soul is the summit of the dianoetic power ([Greek: to akrotaton tes dianoias]), or that power which reasons scientifically; and this summit is our intellect. As, however, our very essence is characterized by reason, this our summit is rational, and though it subsists in energy, yet it has a remitted union with things themselves. Though too it energizes from itself, and contains intelligibles in its essence, yet from its alliance to the discursive nature of soul, and its inclination to that which is divisible, it falls short of the perfection of an intellectual essence and energy profoundly indivisible and united, and the intelligibles which it contains degenerate from the transcendently fulged and self-luminous nature of first intelligibles. Hence, in obtaining a perfectly indivisible knowledge, it requires to be perfected by an intellect whose energy is ever vigilant and unremitted; and it's intelligibles, that they may become perfect, are indigent of the light which proceeds from separate intelligibles. Aristotle, therefore, very properly compares the intelligibles of our intellect to colors, because these require the splendour of the sun, and denominates an intellect of this kind, intellect in capacity, both on account of its subordination to an essential intellect, and because it is from a separate intellect that it receives the full perfection of its nature. The middle part of the rational soul is called by Plato, dianoia, and is that power which, as we have already said, reasons scientifically, deriving the principles of its reasoning, which are axioms from intellect. And the extremity of the rational soul is opinion, which in his Sophista he defines to be that power which knows the conclusion of dianoia. This power also knows the universal in sensible particulars, as that every man is a biped, but it knows only the oti, or that a thing is, but is ignorant of the dioti, or why it is: knowledge of the latter kind being the province of the dianoetic power.
And such is Plato's division of the rational part of our nature, which he very justly considers as the true man; the essence of every thing consisting in its most excellent part.
