Untruth and sophism it knows, not directly, not of its own nature, but merely as something produced outside itself, something which it recognises to be foreign to the verities laid up in itself; in the falsity presented to it, it perceives a clash with its own canon of truth. Dialectic, that is to say, has no knowledge of propositions – collections of words – but it knows the truth, and, in that knowledge, knows what the schools call their propositions: it knows above all, the operation of the soul, and, by virtue of this knowing, it knows, too, what is affirmed and what is denied, whether the denial is of what was asserted or of something else, and whether propositions agree or differ; all that is submitted to it, it attacks with the directness of sense-perception and it leaves petty precisions of process to what other science may care for such exercises. Enneads I,3,
When the Intellect is in upward orientation that [lower part of it] which contains [or, corresponds to] the life of the Soul, is, so to speak, flung down again and becomes like the reflection resting on the smooth and shining surface of a mirror; in this illustration, when the mirror is in place the image appears but, though the mirror be absent or out of gear, all that would have acted and produced an image still exists; so in the case of the Soul; when there is peace in that within us which is capable of reflecting the images of the Rational and Intellectual-Principles these images appear. Then, side by side with the primal knowledge of the activity of the Rational and the Intellectual-Principles, we have also as it were a sense-perception of their operation. Enneads I,4,
But, once more, admitting two distinct principles, something quite separate remembering what sense-perception has first known – still this something must have felt what it is required to remember? No; we may well conceive that where there is to be memory of a sense-perception, this perception becomes a mere presentment, and that to this image-grasping power, a distinct thing, belongs the memory, the retention of the object: for in this imaging faculty the perception culminates; the impression passes away but the vision remains present to the imagination. Enneads IV,3,
But, we will be asked to say what are the experiences, within the earth, upon which the earth-soul is thus to form its decisions: certainly vegetal forms, in so far as they belong to earth have no sensation or perception: in what then, and through what, does such sensation take place, for sensation without organs is too rash a notion. Besides, what would this sense-perception profit the soul? It could not be necessary to knowledge: surely the consciousness of wisdom suffices to beings which have nothing to gain from sensation? This argument is not to be accepted: it ignores the consideration that, apart from all question of practical utility, objects of sense provide occasion for a knowing which brings pleasure: thus we ourselves take delight in looking upon sun, stars, sky, landscape, for their own sake. But we will deal with this point later: for the present we ask whether the earth has perceptions and sensations, and if so through what vital members these would take place and by what method: this requires us to examine certain difficulties, and above all to decide whether earth could have sensation without organs, and whether this would be directed to some necessary purpose even when incidentally it might bring other results as well. Enneads IV,4,
If this theory of ours is sound, bodily organs are necessary to sense-perception, as is further indicated by the reflection that the soul entirely freed of body can apprehend nothing in the order of sense. Enneads IV,4,
The soul, isolated, has no sense-perception; sensations go with the body; sensation itself therefore must occur by means of the body to which the sensations are due; it must be something brought about by association with the body. Enneads IV,4,
At this, sense-impressions would aim at utility. They may serve also to knowledge, but that could be service only to some being not living in knowledge but stupefied as the result of a disaster, and the victim of a Lethe calling for constant reminding: they would be useless to any being free from either need or forgetfulness. This This reflection enlarges the enquiry: it is no longer a question of earth alone, but of the whole star-system, all the heavens, the kosmos entire. For it would follow that, in the sphere of things not exempt from modification, sense-perception would occur in every part having relation to any other part: in a whole, however – having relation only to itself, immune, universally self-directed and self-possessing – what perception could there be? Granted that the percipient must act through an organ and that this organ must be different from the object perceived, then the universe, as an All, can have [no sensation since it has] no organ distinct from object: it can have self-awareness, as we have; but sense-perception, the constant attendant of another order, it cannot have. Enneads IV,4,
Now it is the soul’s character to be ever in the Intellectual sphere, and even though it were apt to sense-perception, this could not accompany that intention towards the highest; to ourselves when absorbed in the Intellectual, vision and the other acts of sense are in abeyance for the time; and, in general, any special attention blurs every other. The desire of apprehension from part to part – a subject examining itself – is merely curiosity even in beings of our own standing, and, unless for some definite purpose, is waste of energy: and the desire to apprehend something external – for the sake of a pleasant sight – is the sign of suffering or deficiency. Enneads IV,4,
This seems to oblige us to accord sense-perception to the earth. Enneads IV,4,
It has been explained that seeing and all sense-perception can occur only through the medium of some bodily substance, since in the absence of body the soul is utterly absorbed in the Intellectual Sphere. Sense-perception being the gripping not of the Intellectual but of the sensible alone, the soul, if it is to form any relationship of knowledge, or of impression, with objects of sense, must be brought in some kind of contact with them by means of whatever may bridge the gap. Enneads IV,5,
Observe these facts: memory follows upon attention; those who have memorized much, by dint of their training in the use of leading indications [suggestive words and the like], reach the point of being easily able to retain without such aid: must we not conclude that the basis of memory is the soul-power brought to full strength? The lingering imprints of the other explanation would tell of weakness rather than power; for to take imprint easily is to be yielding. An impression is something received passively; the strongest memory, then, would go with the least active nature. But what happens is the very reverse: in no pursuit to technical exercises tend to make a man less the master of his acts and states. It is as with sense-perception; the advantage is not to the weak, the weak eye for example, but to that which has the fullest power towards its exercise. In the old, it is significant, the senses are dulled and so is the memory. Enneads IV,6,
It is easy to show that if the Soul were a corporeal entity, there could be no sense-perception, no mental act, no knowledge, no moral excellence, nothing of all that is noble. Enneads IV,7,
But how reconcile this unity with the existence of a reasoning soul, an unreasoning, even a vegetal soul? [It is a question of powers]: the indivisible phase is classed as reasoning because it is not in division among bodies, but there is the later phase, divided among bodies, but still one thing and distinct only so as to secure sense-perception throughout; this is to be classed as yet another power; and there is the forming and making phase which again is a power. But a variety of powers does not conflict with unity; seed contains many powers and yet it is one thing, and from that unity rises, again, a variety which is also a unity. Enneads IV,8,
Possessed of such powers, how does it happen that we do not lay hold of them, but for the most part, let these high activities go idle – some, even, of us never bringing them in any degree to effect? The answer is that all the Divine Beings are unceasingly about their own act, the Intellectual-Principle and its Prior always self-intent; and so, too, the soul maintains its unfailing movement; for not all that passes in the soul is, by that fact, perceptible; we know just as much as impinges upon the faculty of sense. Any activity not transmitted to the sensitive faculty has not traversed the entire soul: we remain unaware because the human being includes sense-perception; man is not merely a part [the higher part] of the soul but the total. Enneads: V I
Are we to think that a being knowing itself must contain diversity, that self-knowledge can be affirmed only when some one phase of the self perceives other phases, and that therefore an absolutely simplex entity would be equally incapable of introversion and of self-awareness? No: a being that has no parts or phases may have this consciousness; in fact there would be no real self-knowing in an entity presented as knowing itself in virtue of being a compound – some single element in it perceiving other elements – as we may know our own form and entire bodily organism by sense-perception: such knowing does not cover the whole field; the knowing element has not had the required cognisance at once of its associates and of itself; this is not the self-knower asked for; it is merely something that knows something else. Enneads V,3,
The reasoning-principle in the Soul acts upon the representations standing before it as the result of sense-perception; these it judges, combining, distinguishing: or it may also observe the impressions, so to speak, rising from the Intellectual-Principle, and has the same power of handling these; and reasoning will develop to wisdom where it recognizes the new and late-coming impressions [those of sense] and adapts them, so to speak, to those it holds from long before – the act which may be described as the soul’s Reminiscence. Enneads V,3,
Still; we perceive by means of the perceptive faculty and are, ourselves, the percipients: may we not say the same of the intellective act? No: our reasoning is our own; we ourselves think the thoughts that occupy the understanding – for this is actually the We – but the operation of the Intellectual-Principle enters from above us as that of the sensitive faculty from below; the We is the soul at its highest, the mid-point between two powers, between the sensitive principle, inferior to us, and the intellectual principle superior. We think of the perceptive act as integral to ourselves because our sense-perception is uninterrupted; we hesitate as to the Intellectual-Principle both because we are not always occupied with it and because it exists apart, not a principle inclining to us but one to which we incline when we choose to look upwards. Enneads V,3,
Next, the intellections would be impressions, that is to say not native act but violence from without: now how is such impressing possible and what shape could the impressions bear? Intellection, again, becomes at this a mere handling of the external, exactly like sense-perception. What then distinguishes it unless that it deals with objects of less extension? And what certitude can it have that its knowledge is true? Or what enables it to pronounce that the object is good, beautiful, or just, when each of these ideas is to stand apart from itself? The very principles of judgement, by which it must be guided, would be [as Ideas] excluded: with objects and canons alike outside it, so is truth. Enneads V,5,
If we are told that they are self-standing entities – the distinct beings Justice and Good – then [supposing them to be outside] the Intellectual Realm will not be a unity nor be included in any unity: all is sundered individuality. Where, then, are they and what spatial distinction keeps them apart? How does the Intellectual-Principle come to meet with them as it travels round; what keeps each true to its character; what gives them enduring identity; what conceivable shape or character can they have? They are being presented to us as some collection of figures, in gold or some other material substance, the work of some unknown sculptor or graver: but at once the Intellectual-Principle which contemplates them becomes sense-perception; and there still remains the question how one of them comes to be Justice and another something else. Enneads V,5,
It is thus, I suppose, that in sense-perception we have belief instead of truth; belief is our lief; we satisfy ourselves with something very different from the original which is the occasion of perception. Enneads V,5,
Many as are the objections to this theory, we pass on for fear of the ridicule we might incur by arguing against a position itself so manifestly ridiculous. We may be content with pointing out that it assigns the primacy to the Non-existent and treats it as the very summit of Existence: in short, it places the last thing first. The reason for this procedure lies in the acceptance of sense-perception as a trustworthy guide to first-principles and to all other entities. Enneads: VI I
Most surprising of all is that, while they make sense-perception their guarantee of everything, they hold that the Real cannot be grasped by sensation; – for they have no right to assign to Matter even so much as resistance, since resistance is a quality. If however they profess to grasp Reality by Intellect, is it not a strange Intellect which ranks Matter above itself, giving Reality to Matter and not to itself? And as their “Intellect” has, thus, no Real-Existence, how can it be trustworthy when it speaks of things higher than itself, things to which it has no affinity whatever? But an adequate treatment of this entity [Matter] and of substrates will be found elsewhere. Enneads: VI I
Differentiation by form or shape is no more out of place than a division based on qualities – heat, cold and the like. If it be objected that qualities go to make bodies what they are, then, we reply, so do blendings, colours, shapes. Since our discussion is concerned with Sensible Substance, it is not strange that it should turn upon distinctions related to sense-perception: this Substance is not Being pure and simple, but the Sensible Being which we call the Universe. Enneads VI,3,
We have remarked that its apparent subsistence is in fact an assemblage of Sensibles, their existence guaranteed to us by sense-perception. But since their combination is unlimited, our division must be guided by the Form-Ideas of living beings, as for example the Form-Idea of Man implanted in Body; the particular Form acts as a qualification of Body, but there is nothing unreasonable in using qualities as a basis of division. Enneads VI,3,
The arts concerned with material objects and making use of perceptible instruments and sense-perception must be classed with Sensible Quality, even though they are dispositions of the Soul, attendant upon its apostasy. Enneads VI,3,
These problems at any rate all serve to show that, while in general it is necessary to look for differences by which to separate things from each other, to hunt for differences of the differences themselves is both futile and irrational. We cannot have substances of substances, quantities of quantities, qualities of qualities, differences of differences; differences must, where possible, be found outside the genus, in creative powers and the like: but where no such criteria are present, as in distinguishing dark-green from pale-green, both being regarded as derived from white and black, what expedient may be suggested? Sense-perception and intelligence may be trusted to indicate diversity but not to explain it: explanation is outside the province of sense-perception, whose function is merely to produce a variety of information; while, as for intelligence, it works exclusively with intuitions and never resorts to explanations to justify them; there is in the movements of intelligence a diversity which separates one object from another, making further differentiation unnecessary. Enneads VI,3,
At the outset we must lay aside all sense-perception; by Intellectual-Principle we know Intellectual-Principle. We reflect within ourselves there is life, there is intellect, not in extension but as power without magnitude, issue of Authentic Being which is power self-existing, no vacuity but a thing most living and intellective – nothing more living, more intelligent, more real – and producing its effect by contact and in the ratio of the contact, closely to the close, more remotely to the remote. If Being is to be sought, then most be sought is Being at its intensest; so too the intensest of Intellect if the Intellectual act has worth; and so, too, of Life. Enneads VI,6,
Now what is the foundation of reasoned plan? Precedent planning, it may be; but still we are forced back to some thing or things determining it. What would these be here? Either sense-perception or intellect. But sense-perception it cannot in this case be: intellect is left; yet, starting from intellect, the conclusion will be knowledge, not therefore the handling of the sensible; what begins with the intellectual and proceeds to the intellectual can certainly not end in dealings with the sensible. Providence, then, whether over living beings or over any part of the universe was never the outcome of plan. Enneads VI,7,
But, at this, sense-perception – even in its particular modes – is involved in the Idea by eternal necessity, in virtue of the completeness of the Idea; Intellectual-Principle, as all-inclusive, contains in itself all by which we are brought, later, to recognise this perfection in its nature; the cause, There, was one total, all-inclusive; thus Man in the Intellectual was not purely intellect, sense-perception being an addition made upon his entry into birth: all this would seem to imply a tendance in that great Principle towards the lower, towards this sphere. Enneads VI,7,
But how could that Principle have such perception, be aware of things of sense? Surely it is untenable on the one hand that sense-perception should exist There, from eternity, and on the other that only upon the debasement of the soul should there be sense-perception here and the accomplishment in this realm of the Act of what was always a power in that? Enneads VI,7,
The Man of the realm of birth has sense-perception: the higher soul enters to bestow a brighter life, or rather does not so much enter as simply impart itself; for soul does not leave the Intellectual but, maintaining that contact, holds the lower life as pendant from it, blending with it by the natural link of Reason-Principle to Reason-Principle: and man, the dimmer, brightens under that illumination. Enneads VI,7,
But how can that higher soul have sense-perception? It is the perception of what falls under perception There, sensation in the mode of that realm: it is the source of the soul’s perception of the sense-realm in its correspondence with the Intellectual. Man as sense-percipient becomes aware of that correspondence and accommodates the sense-realm to the lowest extremity of its counterpart There, proceeding from the fire Intellectual to the fire here which becomes perceptible by its analogy with that of the higher sphere. If material things existed There, the soul would perceive them; Man in the Intellectual, Man as Intellectual soul, would be aware of the terrestrial. This is how the secondary Man, copy of Man in the Intellectual, contains the Reason-Principles in copy; and Man in the Intellectual-Principle contained the Man that existed before any man. The diviner shines out upon the secondary and the secondary upon the tertiary; and even the latest possesses them all – not in the sense of actually living by them all but as standing in under-parallel to them. Some of us act by this lowest; in another rank there is a double activity, a trace of the higher being included; in yet another there is a blending of the third grade with the others: each is that Man by which he acts while each too contains all the grades, though in some sense not so. On the separation of the third life and third Man from the body, then if the second also departs – of course not losing hold on the Above – the two, as we are told, will occupy the same place. No doubt it seems strange that a soul which has been the Reason-Principle of a man should come to occupy the body of an animal: but the soul has always been all, and will at different times be this and that. Enneads VI,7,
But this is to anticipate: our enquiry was How there can be sense-perception in man without the implication that the Divine addresses itself to the realm of process. We maintained, and proved, that the Divine does not look to this realm but that things here are dependent upon those and represent them and that man here, holding his powers from Thence, is directed Thither, so that, while sense makes the environment of what is of sense in him, the Intellectual in him is linked to the Intellectual. Enneads VI,7,
What we have called the perceptibles of that realm enter into cognisance in a way of their own, since they are not material, while the sensible sense here – so distinguished as dealing with corporeal objects – is fainter than the perception belonging to that higher world; the man of this sphere has sense-perception because existing in a less true degree and taking only enfeebled images of things There – perceptions here are Intellections of the dimmer order, and the Intellections There are vivid perceptions. Enneads VI,7,
