Guthrie-Plotinus: sense-nature

As there are two kinds of being (or, existence), one of sensation, and the other intelligible, it is preferable for the soul to live in the intelligible world; nevertheless, as a result of her nature, it is necessary for her also to participate in sense-affairs. Since she occupies only an intermediate rank, she must not feel wronged at not being the best of beings. Though on one hand her condition be divine, on the other she is located on the limits of the intelligible world, because of her affinity for sense-nature. She causes this nature to participate in her powers, and she even receives something therefrom, when, instead of managing the body without compromising her own security, she permits herself to be carried away by her own inclination to penetrate profoundly within it, ceasing her complete union with the universal Soul. Besides, the soul can rise above the body after having learned to feel how happy one is to dwell on high, by the experience of things seen and suffered here below, and after having appreciated the true Good by the comparison of contraries. Indeed the knowledge of the good becomes clearer by the experience of evil, especially among souls which are not strong enough to know evil before having experienced it. [Ennead IV,8 (6) 7]

Above existence, therefore, is the One. This has by us been proved as far as could reasonably be expected, and as far as such subjects admit of demonstration. In the second rank are Existence and Intelligence; in the third, the Soul. But if these three principles, the One, Intelligence, and the Soul, as we have said, obtain in nature, three principles must also obtain within us. I do not mean that these three principles are in sense-objects, for they are separate therefrom; they are outside of the sense-world, as the three divine principles are outside of the celestial sphere, and, according to Plato’s expression, they constitute the “the interior man.” Our soul, therefore, is something divine; it has a nature different (from sense-nature), which conforms to that of the universal Soul. Now the perfect Soul possesses intelligence; but we must distinguish between the intelligence that reasons (the discursive reason), and the Intelligence that furnishes the principles of reasoning (pure intelligence). The discursive reason of the soul has no need, for operation, of any bodily organ; in its operations, it preserves all its purity, so that it is capable of reasoning purely. When separated from the body, it must, without any hesitation, be ranked with highest intellectual entities. There is no need of locating it in space; for, if it exist within itself, outside of body, in an immaterial condition, it is evidently not mingled with the body, and has none of its nature. Consequently Plato says, “The divinity has spread the Soul around the world.” What he here means is that a part of the Soul remains in the intelligible world. Speaking of our soul he also says, “she hides her head in heaven.” He also advises us to wean the soul from the body; and he does not refer to any local separation, which nature alone could establish. He means that the soul must not incline towards the body, must not abandon herself to the phantoms of imagination, and must not, thus, become alienated from reason. He means that the soul should try to elevate to the intelligible world her lower part which is established in the sense-world, and which is occupied in fashioning the body. [Ennead V,1 (10) 10]

As the human reason which undertakes to examine the question here raised is not one, but divided, it makes use of corporeal nature in its researches, by borrowing its principles. That is why reason, thinking it intelligible being, similar to bodies, divides it, doubting its unity. It could not be otherwise, because its investigation was not founded on the proper immanent principles. We must, therefore, in our discussion about the one universal Essence, choose principles capable of enlisting support, principles that would be intellectual, that is, would connect with intelligible entities, and veritable being. For since our sense-nature is agitated by continual flux, being subject to all kinds of changes, trending towards all directions of space; it should consequently be called not “being,” but generation, or becoming. The eternal Essence, on the contrary, is not divided; it subsists ever in the same manner and in the same state, neither is born, nor perishes; occupies neither place nor space; does not reside in any determinate location; neither enters, nor issues, but remains in itself. A discussion about the nature of bodies begins with this (physical) nature, and the things that are related to it, which (deductively) give rise to probable proofs by the aid of syllogisms equally probable. But when we deal with intelligible entities, our starting-point must be the nature of the being considered; principles have to be legitimately derived therefrom; and then, without surreptitiously substituting any other nature (inductively), borrow from the intelligible Being itself the conception formed about it; for being, or whatness, is everywhere taken as principle; and it is said that the definition of an object, when well made, sets forth many of its accidents. Therefore, when we are dealing with things where being is everything, we must, so much the more, apply our whole attention to this being; base all our (arguments) thereon, and refer everything to it. [Ennead VI,5 (23) 2]

How can the intelligible, which has no extension, penetrate into the whole body of the universe, which has no such extension? How does it remain single and identical, and how does it not split up? This question has been raised several times, and we sought to answer it, so as to leave no uncertainty. We have often demonstrated that the things are thus; nevertheless, it will be well to give some further convincing proofs, although we have already given the strongest demonstration, and the most evident one, by teaching the quality of the nature of the intelligible, explaining that it is not a vast mass, some enormous stone which, located in space, might be said to occupy an extension determined by its own magnitude, and would be incapable of going beyond its limits; for its mass and its power would be measured by its own nature, which is that of a stone. (The intelligible Essence, on the contrary,) being the primary nature, has no extension that is limited or measured, because it itself is the measure of the sense-nature; and because it is the universal power without any determinate magnitude. Nor is it within time, because the time is continually divided into intervals, while eternity dwells in its own identity, dominating and surpassing time by its perpetual power, though this seemed to have an unlimited course. Time may be compared to a line which, while extending indefinitely, ever depends from a point, and turns around it; so, that, into whatever place it advances, it always reveals the immovable point around which it moves in a circle. If, by nature, time be in the same relation (as is this line with its centre), and if the identical Essence be infinite by its power as well as by its eternity, by virtue of its infinite power it will have to produce a nature which would in some way be parallel to this infinite power, which rises with it, and depends from it, and which finally, by the movable course of time, tries to equal this power which remains movable in itself. But then even this power of the intelligible Essence remains superior to the universe, because the former determines the extension of the latter. [Ennead VI,5 (23) 11]
