Guthrie-Plotinus: sensitive

If, however, the Soul be one, why is some one soul reasonable, another irrational, or some other one merely vegetative? The indivisible part of the soul consists in reason, which is not divided in the bodies, while the part of the divisible soul in the bodies (which, though being one in herself, nevertheless divides herself in the bodies, because she sheds sentiment everywhere), must be regarded as another power of the soul (the sensitive power); likewise, the part which fashions and produces the bodies is still another power (the vegetative power); nevertheless, this plurality of powers does not destroy the unity of the soul. For instance, in a grain of seed there are also several powers; nevertheless this grain of seed is one, and from this unity is born a multiplicity which forms a unity. [Ennead IV,9 (8) 3]

One more subject remains to be considered. The lowest power of the universal Soul (the inferior soul), rests on the earth, and thence radiates abroad throughout the universe. The (higher, or celestial) power (of the world-Soul) which, by nature, possesses sensation, opinion, and reasoning, resides in the celestial spheres, whence it dominates the inferior power, and communicates life to it. It thereby moves the inferior power, embracing it in a circle; and it presides over the universe as it returns (from the earth) to the celestial spheres. The inferior power, being circularly embraced by the superior power, reflects upon itself, and thus operates on itself a conversion by which it imparts a movement of rotation to the body within which it reacts. (This is how motion starts) in a sphere that is at rest: as soon as a part moves, the movement spreads to the rest of it, and the sphere begins to revolve. Not otherwise is our body; when our soul begins to move, as in joy, or in the expectation of welfare, although this movement be of a kind very different from that natural to a body, this soul-movement produces local motion in the body. Likewise the universal Soul, on high, while approaching the Good, and becoming more sensitive (to its proximity), thereby impresses the body with the motion proper to it, namely, the local movement. (Our own human) sense-(faculty), while receiving its good from above, and while enjoying the pleasures proper to its nature, pursues the Good, and, inasmuch as the Good is everywhere present, it is borne everywhere. The intelligence is moved likewise; it is simultaneously at rest and in motion, reflecting upon itself. Similarly the universe moves in a circle, though simultaneously standing still. [Ennead II,2 (14) 3]

It is to this (universal) Soul especially that may be applied these words of Plato: “The general Soul cares for all that is inanimate.” The other (individual) souls are in different conditions. “The Soul (adds Plato), circulates around the heavens successively assuming divers forms”; that is, the forms of thought, sense or growth. The part which dominates in the soul fulfills its proper individual function; the others remain inactive, and somehow seem exterior to them. In man, it is not the lower powers of the soul that dominate. They do indeed co-exist with the others. Neither is it always the best power (reason), which always dominates; for the inferior powers equally have their place. Consequently, man (besides being a reasonable being) is also a sensitive being, because he possesses sense-organs. In many respects, he is also a vegetative being; for his body feeds and grows just like a plant. All these powers (reason, sensibility, growth), therefore act together in the man; but it is the best of them that characterizes the totality of the man (so that he is called a “reasonable being”). On leaving the body the soul becomes the power she had preponderatingly developed. Let us therefore flee from here below, and let us raise ourselves to the intelligible world, so as not to fall into the pure sense-life, by allowing ourselves to follow sense-images, or into the life of growth, by abandoning ourselves to the pleasures of physical love, and to gormandizing; rather, let us rise to the intelligible world, to the intelligence, to the divinity! [Ennead III,4 (15) 2]

The musician allows himself to be easily moved by beauty, and admires it greatly; but he is not able by himself to achieve the intuition of the beautiful. He needs the stimulation of external impressions. Just as some timorous being is awakened by the least noise, the musician is sensitive to the beauty of the voice and of harmonies. He avoids all that seems contrary to the laws of harmony and of unity, and enjoys rhythm and melodies in instrumental and vocal music. After these purely sensual intonations, rhythm and tunes, he will surely in them come to distinguish form from matter, and to contemplate the beauty existing in their proportions and relations. He will have to be taught that what excites his admiration in these things, is their intelligible harmony, the beauty it contains, and, in short, beauty absolute, and not particular. He will have to be introduced to philosophy by arguments that will lead him to recognize truths that he ignored, though he possessed them instinctively. Such arguments will be specified elsewhere. [Ennead I,3 (20) 1]

Enough of this. Let us return to the question from which we digressed. We granted that the desires, pains and pleasures (considered not only as sentiments, but as passions), originate in the constitution of the organized and living body. Must the same origin be assigned to the irascible (power)? Were this so, we would have several questions to ask: Does anger belong to the entire organism, or only to a particular organ, such as the heart when so disposed, or to the bile, as long as it is part of a living body? Is anger different from the principle which gives the body a trace of the soul, or is it an individual power, which depends on no other power, whether irascible or sensitive? [Ennead IV,4 (28) 28]

It might, indeed, be objected that (the divinity) knew that the living organism would be exposed to heat, cold, and other physical conditions; and that as a result of this knowledge, to keep them from perishing, He granted them, as tools, senses and organs. In our turn we shall ask whether the divinity gave the organs to the living organisms that already possessed the senses, or whether, He endowed souls with senses and organs simultaneously. In the latter case, though they were souls, they did not previously possess the sensitive faculties. But if the souls possessed the sensitive faculties since the time they were produced, and if they were produced (with these faculties) in order to descend into generation, then it was natural for them to do so. In this case it seems that it must be contrary to their nature to avoid generation, and to dwell in the intelligible world. They would seem made to belong to the body, and to live in evil. Thus divine Providence would retain them in evil, and the divinity would arrive at this result by reasoning; in any case, He would have reasoned. [Ennead VI,7 (38) 1]

It may further be objected that matter gives essence to material things, as Socrates   gives essence to the white that is in him. We will answer that what possesses a superior degree of Essence may well confer a lesser degree of essence to what possesses a still inferior degree thereof, but that the reciprocal or converse condition is impossible. Now, as form is more essence than matter, essence cannot be predicated equally of matter and form, and “being” is not a genus whose species is matter, form and the combination. These three things have several common characteristics, as we have already said, but they differ in respect to essence; for when something which possesses a superior degree of essence approaches something which possesses an inferior degree (as when form approaches matter), this thing, although anterior in (the ontological) order, is posterior in respect to being; consequently, if matter, form and the combination be not “beings” equally, no longer is being for them something common, like a genus. Nevertheless, “being” will be in a less narrow relation with things which are posterior to matter, to form, and to the combination, though it gives each of them the property of belonging to themselves. It is thus that life has different degrees, one stronger, the other weaker, and that the images of a same object are some more lively, others more obscure. If essence be measured by a lower degree of essence, and if the superior degree which exists in other things be omitted, essence thus considered will be a common element. But that is not a good way of procedure. Indeed, each whole differs from the others, and the lesser degree of essence does not constitute something that was common to all; just as, for life, there is not something common to vegetative life, to sensitive life, and rational life. [Ennead VI,3 (44) 7]

The beings which possess a nature inferior to the star-Souls, that is, men, occupy the second rank in the universe, and play in it the same part played in us by the second power of the soul (the discursive reason). The other beings, that is, the animals, occupy about the same rank occupied in us by the lowest (or vegetative) power of the soul; for all these powers in us are not of equal rank. Consequently, all the beings which are in the heaven, or which are distributed in the universe are animated beings, and derive their life from the total Reason of the universe (because it contains the “seminal reasons” of all living beings). None of the parts of the universe, whatever be its greatness, possesses the power of altering the reasons, nor the beings engendered with the co-operation of these reasons. It may improve or degrade these beings, but cannot deprive them of their individual nature. It degrades them by injuring either their body or their soul; which occurs when an accident becomes a cause of vice for the soul which partakes of the passions of the body (the sensitive and vegetative soul) and which is given over to the inferior principle (to the animal) by the superior principle (the reasonable soul); or when the body, by its poor organization, hinders the actions in which the soul needs its co-operation; then it resembles a badly attuned lyre, which is incapable of producing sounds which could form a perfect harmony. [Ennead II,3 (52) 13]

The real Man differs from the body; pure from every passion, he possesses the intellectual virtues, virtues which reside in the soul, either when she is separated from the body, or when she is — as usually here below — only separable by philosophy; for even when she seems to us entirely separated, the soul is, in this life, ever accompanied by a lower sensitive part, or part of growth, which she illuminates. [Ennead I,1 (53) 10]
