How does it happen that we possess principles that are so elevated, almost in spite of ourselves, and for the most part without busying ourselves about them? For there are even men who never notice them. Nevertheless these principles, that is, intelligence, and the principle superior to intelligence, which ever remains within itself (that is, the One), these two principles are ever active. The case is similar with the soul. She is always in motion; but the operations that go on within her are not always perceived; they reach us only when they succeed in making themselves felt. When the faculty that is active within us does not transmit its action to the power that feels, this action is not communicated to the entire soul; however, we may not be conscious thereof because, although we possess sensibility, it is not this power, but the whole soul that constitutes the man. So long as life lasts, each power of the soul exercises its proper function by itself; but we know it only when communication and perception occur. In order to perceive the things within us, we have to turn our perceptive faculties towards them, so that (our soul) may apply her whole attention thereto. The person that desires to hear one sound must neglect all others, and listen carefully on its approach. Thus we must here close our senses to all the noises that besiege us, unless necessity force us to hear them, and to preserve our perceptive faculty pure and ready to listen to the voices that come from above. [Ennead V,1 (10) 12]

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]

Can memory be referred to sensibility? Is the faculty that feels also the one that remembers? But if the image of the soul (the irrational soul) possess the memory, as we said above, there would be in us two faculties that will feel. Further, if sensibility be capable of grasping notions, it will also have to perceive the conceptions of discursive reason, or it will be another faculty that will perceive both. [Ennead IV,3 (27) 29]

Are we compelled to remember sensations by sensibility, whether it be the same power which feels sensation, and which remembers sensation, or is it also discursive reason which conceives and remembers conceptions. But the men who reason the best are not those who also remember the best; and those who have equally delicate senses, do not all, on that account, have an equally good memory. On the contrary, some have delicate senses, while others have a good memory, without however being capable of perceiving equally well. On the other hand, if feeling and remembering be mutually independent, there will be (outside of sensibility) another power which will remember things formerly perceived by sensation, and this power will have to feel what it is to remember. [Ennead IV,3 (27) 29]

What is the relation of the sense-power within the superior Soul (or, in the rational soul)? Intelligible sensation perceives (intelligible) objects that, speaking strictly, are not sensible, and corresponds to the (intelligible) manner in which they are perceivable. Thus (by this intelligible sense-power) the Soul perceives the supersensual harmony and also the sensual, but in a manner such as the sense-man perceives it, relating it so far as possible to the superior harmony, just as he relates the earthly fire to the intelligible Fire, which is above, and which the superior Soul felt in a manner suitable to the nature of this fire. If the bodies which are here below were up there also, the superior Soul would feel them and perceive them. The man who exists on high is a Soul disposed in some particular manner, capable of perceiving these objects; hence the man of the last degree (the sense-man) being the image of the intelligible Man, has reasons (faculties) which are also images (faculties possessed by the superior Man). The man who exists in the divine Intelligence constitutes the Man superior to all men. He illuminates the second (the reasonable man), who in his turn illuminates the third (the sense-man). The man of this last degree somewhat possesses the two others; he is not produced by them, he is rather united to them. The man who constitutes us actualizes himself as the man of the last degree. The third receives something of the second; and the second is the actualization of the first. Each man’s nature depends on the “man” according to whom he acts (the man is intellectual, reasonable, or sensual according as he exercises intelligence, discursive reason, or sensibility). Each one of us possesses the three men in one sense (potentially); and does not possess them in another (in actualization; that is, he does not simultaneously exercise intellect, reason, or sense). [Ennead VI,7 (38) 6]

Such considerations have been arrived at merely as result of scrutiny of the consequences of the principles laid down. Our purpose was to discover how sensibility occurs in the man himself, without intelligible things falling into generation. We recognized and demonstrated that intelligible things do not incline towards sense-things, but that, on the contrary, it is the latter that aspire and rise to the former, and imitate them; that the sense-man derives from the intellectual man the power of contemplating intelligible entities, though the sense-man remain united to sense-things, as the intellectual man remains united to the intelligible entities. Indeed, intelligible things are in some respects sensual; and we may call them such because (ideally) they are Bodies, but they are perceived in a manner different from bodies. Likewise, our sensations are less clear than the perception which occurs in the intelligible world, and that we also call Sensation, because it refers to Bodies (which exist on high only in an ideal manner). Consequently, we call the man here below sensual because he perceives less well things which themselves are less good; that is, which are only images of intelligible things. We might therefore say that sensations here below are obscure thoughts, and that the Thoughts on high are distinct Sensations. Such are our views about sensibility. [Ennead VI,7 (38) 7]

It is not otherwise with water and air. If by their nature these elements were more consistent, they would reveal the universal Soul; but as their essence is dispersed, they do not reveal the power that animates them. In a similar case are the fluids occurring in our body, as, for instance, the blood; the flesh, which seems animated, is formed at the expense of the blood. The latter must therefore enjoy the presence of the soul, though it seem deprived of the (soul) because (the blood) manifests no sensibility, opposes no resistance, and by its fluidity easily separates itself from the soul that vivifies it, as happens to the three elements already mentioned. Likewise the animals which Nature forms out of condensed air feel without suffering. As fixed and permanent light penetrates the air so long as the air itself is permanent, the soul also penetrates the atmosphere surrounding her without being absorbed by it. Other elements are in the same case. [Ennead VI,7 (38) 11]

Let us consider the implications of the principles we have studied. If that which a being receives as good be everywhere a form, if the good of matter be a form, we might ask ourselves whether matter, granting it here the faculty of volition, would even wish to be a form? Such a wish would be tantamount to a wish to be destroyed. (But matter could not wish this), for every being seeks its own good. But perhaps matter might not wish to be matter, but simply to be essence; possessing which, matter would wish to free itself from all the evil within it. But how can that which is evil (for such is the nature of matter) desire the good? Besides, we are not attributing desire to matter itself. It was only to meet the exigencies of the discussion that we employed the hypothesis which accorded sensibility to matter, if indeed it can be granted to matter without destroying its nature. We have at least shown that when form has come, as a dream of the Good, to unite itself to matter, the latter found itself in a better condition. [Ennead VI,7 (38) 28]

Supposing then that the pleasure does not accompany the good, but that anterior to pleasure there have existed something which would have naturally given rise to it (because of its goodness); why then might not the good be considered lovable? But the mere assertion that good is lovable, already implies that it is accompanied by pleasure. But supposing now that the good could exist without being lovable (and consequently not accompanied by pleasure). In that case, even in presence of the good, the being that possesses sensibility will not know that the good is present. What would however hinder a being from knowing the presence of the good without feeling any emotion at its possession, which would exactly represent the case of the temperate man who lacks nothing? The result would be that pleasure could not be suitable to the First (being), not only because He is simple, but also because pleasure results from the acquisition of what is lacking (and the First lacks nothing, therefore could not feel pleasure). [Ennead VI,7 (38) 29]

Once more it may be objected that it is essential to wisdom to be self-conscious, for happiness resides only in actualized wisdom. This objection would hold if reason and wisdom were incidentals. But if the hypostatic substance of wisdom consist in an essence (being), or rather, in being itself, and if this being do not perish during sleep, nor during unconsciousness, if consequently the activity of being continue to subsist in him; if by its very nature this (being) ceaselessly watch, then the virtuous man must even in this state (of sleep or unconsciousness), continue to exercise his activity. Besides, this activity is ignored only by one part of himself, and not by himself entirely. Thus during the operation of the actualization of growth, the perception of its activity is not by his sensibility transmitted to the rest of the man. If our personality were constituted by this actualization of growth, we would act simultaneously with it; but we are not this actualization, but that of the intellectual principle, and that is why we are active simultaneously with this (divine intellectual activity). [Ennead I,4 (46) 9]

But why should this whole (soul-) part that is superior to sensation be assigned to the soul rather than to intelligence? Because the power of the soul consists in reasoning, and because all these operations belong to the discursive reason. But why can we not simply assign to it, in addition, self-consciousness, which would immediately clear up this inquiry? Because the nature of discursive reason consists in considering exterior things, and in scrutinizing their diversity, while to intelligence we attribute the privilege of contemplating itself, and of contemplating its own contents. But what hinders discursive reason, by some other faculty of the soul, from considering what belongs to it? Because, in this case, instead of discursive reason and reasoning, we would have pure Intelligence. But what then hinders the presence of pure Intelligence within the soul? Nothing, indeed. Shall we then have a right to say that pure Intelligence is a part of the soul? No indeed; but still we would have the right to call it “ours.” It is different from, and higher than discursive reason; and still it is “ours,” although we cannot count it among the parts of the soul. In one respect it is “ours,” and in another, is not “ours;” for at times we make use of it, and at other times we make use of discursive reason; consequently, intelligence is “ours” when we make use of it; and it is not “ours” when we do not make use of it. But what is the meaning of “making use of intelligence”? Does it mean becoming intelligence, and speaking in that character, or does it mean speaking in conformity with intelligence? For we are not intelligence; we speak in conformity with intelligence by the first part of discursive reason, the part that receives impressions from Intelligence. We feel through sensation, and it is we who feel. Is it also we who conceive and who simultaneously are conceived? Or is it we who reason, and who conceive the intellectual notions which enlighten discursive reason? We are indeed essentially constituted by discursive reason. The actualizations of Intelligence are superior to us, while those of sensation are inferior; as to us, “we” are the principal part of the soul, the part that forms a middle power between these two extremes, now lowering ourselves towards sensation, now rising towards Intelligence. We acknowledge sensibility to be ours because we are continually feeling. It is not as evident that intelligence is ours, because we do not make use of it continuously, and because it is separated, in this sense, that it is not intelligence that inclines towards us, but rather we who raise our glances towards intelligence. Sensation is our messenger, Intelligence is our king. [Ennead V,3 (49) 3]
