Introduction to the Philosophy and Writings of Plato

by Thomas Taylor

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.

After this follows the irrational nature, the summit of which is the phantasy, or that power which perceives every thing accompanied with figure and interval; and on this account it may be called a figured intelligence ([Greek: morphotike noesis]). This power, as Jamblichus beautifully observes, groups upon, as it were, and fashions all the powers of the soul; exciting in opinion the illuminations from the senses, and fixing in that life which is extended with body, the impressions which descend from intellect. Hence, slays Proclus, it folds itself about the indivisibility of true intellect, conforms itself to all formless species, and becomes perfectly every thing, from which the dianoetic power and our indivisible reason consists. Hence too, it is all things passively which intellect is impassively, and on this account Aristotle calls it passive intellect. Under this subsist anger and desire, the former resembling a raging lion, and the latter a many-headed beast; and the whole is bounded by sense, which is nothing more than a passive perception of things, and on this account is justly said by Plato, to be rather passion than knowledge; since the former of these is characterized by alertness, and the latter by energy.

Further still, in order that the union of the soul with this gross terrestrial body may be effected in a becoming manner, two vehicles, according to Plato, are necessary as media, one of which is ethereal, and the other aerial, and of these, the ethereal vehicle is simple and immaterial, but the aerial, simple and material; and this dense earthly body is composite and material.

The soul thus subsisting as a medium between natures impartible and such as are divided about bodies, it produces and constitutes the latter of these; but establishes in itself the prior causes from which it proceeds. Hence it previously receives, after the manner of an exemplar, the natures to which it is prior as their cause; but it possesses through participation, and as the blossoms of first natures, the causes of its subsistence. Hence it contains in its essence immaterial forms of things material, incorporeal of such as are corporeal, and extended of such as are distinguished by interval. But it contains intelligibles after the manner of an image, and receives partibly their impartible forms, such as are uniform variously, and such as are immovable, according to a self-motive condition. Soul therefore is all things, and is elegantly said by Olympiodorus to be an omniform statue ([Greek: pammorphon agalma]): for it contains such things as are first through participation, but such as are posterior to its nature, after the manner of an exemplar.

As, too, it is always moved; and this always is not eternal, but temporal, for that which is properly eternal, and such is intellect, is perfectly stable, and has no transitive energies, hence it is necessary that its motions should be periodic. For motion is a certain mutation from some things into others. And beings are terminated by multitudes and magnitudes. These therefore being terminated, there can neither be an infinite mutation, according to a right line, nor can that which is always moved proceed according to a finished progression. Hence that which is always moved will proceed from the same to the same; and will thus form a periodic motion. Hence, too, the human, and this also is true of every mundane soul, uses periods and restitutions of its proper life. For, in consequence of being measured by time, it energizes transitively, and possesses a proper motion. But every thing which is moved perpetually and participates of time, revolves periodically and proceeds from the same to the same. And hence the soul, from possessing motion, and energizing according to time, will both possess periods of motion and restitutions to its pristine state.

Again, as the human soul, according to Plato, ranks among the number of those souls that sometimes follow the mundane divinities, in consequence of subsisting immediately after daemons and heroes, the perpetual attendants of the gods, hence it possesses a power of descending infinitely into generation, or the sublunary region, and of ascending from generation to real being. For since it does not reside with divinity through an infinite time, neither will it be conversant with bodies through the whole succeeding time. For that which has no temporal beginning, both according to Plato and Aristotle, cannot have an end; and that which has no end, is necessarily without a beginning. It remains, therefore, that every soul must perform periods, both of ascensions from generation, and of descensions into generation; and that this will never fail, through an infinite time.

From all this it follows that the soul, while an inhabitant of earth, is in a fallen condition, an apostate from deity, an exile from the orb of light. Hence Plato, in the 7th book of his Republic, considering our life with reference to erudition and the want of it, assimilates us to men in a subterranean cavern, who have been there confined from their childhood, and so fettered by chains as to be only able to look before them to the entrance of the cave which expands to the light, but incapable through the chain of turning themselves round. He supposes too, that they have the light of a fire burning far above and behind them; and that between the fire and the fettered men, there is a road above, along which a low wall is built. On this wall are seen men bearing utensils of every kind, and statues in wood and stone of men and other animals. And of these men some are speaking and others silent. With respect to the fettered men in this cave, they see nothing of themselves or another, or of what is carrying along, but the shadows formed by the fire falling on the opposite part of tho cave. He supposes too, that the opposite part of this prison has an echo; and that in consequence of this the fettered men, when they hear any one speak, will imagine that it is nothing else than the passing shadow.
