The Will of God is able to cope with the ceaseless flux and escape of body stuff by ceaselessly reintroducing the known forms in new SUBSTANCES, thus ensuring perpetuity not to the particular item but to the unity of idea: now, seeing that objects of this realm possess no more than duration of form, why should celestial objects, and the celestial system itself, be distinguished by duration of the particular entity? Let us suppose this persistence to be the result of the all-inclusiveness of the celestial and universal – with its consequence, the absence of any outlying matter into which change could take place or which could break in and destroy. Enneads: II I
A soul, then, of the minor degree – reproducing, indeed, that of the Divine sphere but lacking in power inasmuch as it must exercise its creative act upon inferior stuff in an inferior region – the SUBSTANCES taken up into the fabric being of themselves repugnant to duration; with such an origin the living things of this realm cannot be of strength to last for ever; the material constituents are not as firmly held and controlled as if they were ruled immediately by a Principle of higher potency. Enneads: II I
But all this does not assure us that the earth to be visible must contain fire: light is sufficient: snow, for example, and other extremely cold SUBSTANCES gleam without the presence of fire – though of course it might be said that fire was once there and communicated colour before disappearing. Enneads: II I
Some enquiry must be made into what is known as the complete transfusion of material SUBSTANCES. Enneads: II VII.
But there are those who, admitting coalescence, confine it to the qualities: to them the material SUBSTANCES of two bodies are in contact merely, but in this contact of the matter they find footing for the qualities of each. Enneads: II VII.
Their view is plausible because it rejects the notion of total admixture and because it recognizes that the masses of the mixing bodies must be whittled away if there is to be mixture without any gap, if, that is to say, each substance must be divided within itself through and through for complete interpenetration with the other. Their theory is confirmed by the cases in which two mixed SUBSTANCES occupy a greater space than either singly, especially a space equal to the conjoined extent of each: for, as they point out, in an absolute interpenetration the infusion of the one into the other would leave the occupied space exactly what it was before and, where the space occupied is not increased by the juxtaposition, they explain that some expulsion of air has made room for the incoming substance. They ask further, how a minor quantity of one substance can be spread out so as to interpenetrate a major quantity of another. In fact they have a multitude of arguments. Enneads: II VII.
Those, on the other hand, that accept “complete transfusion,” might object that it does not require the reduction of the mixed things to fragments, a certain cleavage being sufficient: thus, for instance, sweat does not split up the body or even pierce holes in it. And if it is answered that this may well be a special decree of Nature to allow of the sweat exuding, there is the case of those manufactured articles, slender but without puncture, in which we can see a liquid wetting them through and through so that it runs down from the upper to the under surface. How can this fact be explained, since both the liquid and the solid are bodily SUBSTANCES? Interpenetration without disintegration is difficult to conceive, and if there is such mutual disintegration the two must obviously destroy each other. Enneads: II VII.
But then, where is the water? and (if only a quality has entered) why is there a change of volume? The pulp has been expanded by the addition: that is to say it has received magnitude from the incoming substance but if it has received the magnitude, magnitude has been added; and a magnitude added has not been absorbed; therefore the combined matter must occupy two several places. And as the two mixing SUBSTANCES communicate quality and receive matter in mutual give and take so they may give and take magnitude. Indeed when a quality meets another quality it suffers some change; it is mixed, and by that admixture it is no longer pure and therefore no longer itself but a blunter thing, whereas magnitude joining magnitude retains its full strength. Enneads: II VII.
But let it be understood how we came to say that body passing through and through another body must produce disintegration, while we make qualities pervade their SUBSTANCES without producing disintegration: the bodilessness of qualities is the reason. Matter, too, is bodiless: it may, then, be supposed that as Matter pervades everything so the bodiless qualities associated with it – as long as they are few – have the power of penetration without disintegration. Anything solid would be stopped either in virtue of the fact that a solid has the precise quality which forbids it to penetrate or in that the mere coexistence of too many qualities in Matter (constitutes density and so) produces the same inhibition. Enneads: II VII.
This would mean that the qualities of two SUBSTANCES do not bring about the mixing by merely being qualities but by being apt to mixture; nor does Matter refuse to enter into a mixing as Matter but as being associated with a quality repugnant to mixture; and this all the more since it has no magnitude of its own but only does not reject magnitude. Enneads: II VII.
May we not think that, similarly, the light belonging to bodies that have been dissolved remains in being while the solid total, made up of all that is characteristic, disappears? It might be said that the seeing is merely the sequel to some law (of our own nature), so that what we call qualities do not actually exist in the SUBSTANCES. Enneads IV,4,
Now if, thus, it enters into other SUBSTANCES from something gleaming, could it exist in the absence of its container? There is a distinction to be made: if it is a quality, some quality of some substance, then light, equally with other qualities, will need a body in which to lodge: if, on the contrary, it is an activity rising from something else, we can surely conceive it existing, though there be no neighbouring body but, if that is possible, a blank void which it will overleap and so appear on the further side: it is powerful, and may very well pass over unhelped. If it were of a nature to fall, nothing would keep it up, certainly not the air or anything that takes its light; there is no reason why they should draw the light from its source and speed it onwards. Enneads IV,5,
All existences, as long as they retain their character, produce – about themselves, from their essence, in virtue of the power which must be in them – some necessary, outward-facing hypostasis continuously attached to them and representing in image the engendering archetypes: thus fire gives out its heat; snow is cold not merely to itself; fragrant SUBSTANCES are a notable instance; for, as long as they last, something is diffused from them and perceived wherever they are present. Enneads: V I
More truly, this is the one God who is all the gods; for, in the coming to be of all those, this, the one, has suffered no diminishing. He and all have one existence while each again is distinct. It is distinction by state without interval: there is no outward form to set one here and another there and to prevent any from being an entire identity; yet there is no sharing of parts from one to another. Nor is each of those divine wholes a power in fragment, a power totalling to the sum of the measurable segments: the divine is one all-power, reaching out to infinity, powerful to infinity; and so great is God that his very members are infinites. What place can be named to which He does not reach? Great, too, is this firmament of ours and all the powers constellated within it, but it would be greater still, unspeakably, but that there is inbound in it something of the petty power of body; no doubt the powers of fire and other bodily SUBSTANCES might themselves be thought very great, but in fact, it is through their failure in the true power that we see them burning, destroying, wearing things away, and slaving towards the production of life; they destroy because they are themselves in process of destruction, and they produce because they belong to the realm of the produced. Enneads V,8,
This conclusion must not however prevent our seeking in the actual substance of the Sensible world an element held in common by Matter, by Form and by their Composite, all of which are designated as SUBSTANCES, though it is not maintained that they are Substance in an equal degree; Form is usually held to be Substance in a higher degree than Matter, and rightly so, in spite of those who would have Matter to be the more truly real. Enneads: VI I
There is further the distinction drawn between what are known as First and Second Substances. But what is their common basis, seeing that the First are the source from which the Second derive their right to be called SUBSTANCES? But, in sum, it is impossible to define Substance: determine its property, and still you have not attained to its essence. Even the definition, “That which, numerically one and the same, is receptive of contraries,” will hardly be applicable to all SUBSTANCES alike. Enneads: VI I
But perhaps we should rather speak of some single category, embracing Intellectual Substance, Matter, Form, and the Composite of Matter and Form. One might refer to the family of the Heraclids as a unity in the sense, not of a common element in all its members, but of a common origin: similarly, Intellectual Substance would be Substance in the first degree, the others being SUBSTANCES by derivation and in a lower degree. Enneads: VI I
But what is the objection to including everything in a single category, all else of which existence is predicated being derived from that one thing, Existence or Substance? Because, granted that things be no more than modifications of Substance, there is a distinct grading of SUBSTANCES themselves. Moreover, the single category does not put us in a position to build on Substance, or to grasp it in its very truth as the plausible source of the other SUBSTANCES. Enneads: VI I
Supposing we grant that all things known as SUBSTANCES are homogeneous as possessing something denied to the other genera, what precisely is this something, this individuality, this subject which is never a predicate, this thing not present in any thing as in a subject, this thing which does not owe its essential character to any other thing, as a quality takes character from a body and a quantity from a substance, as time is related to motion and motion to the moved? The Second Substance is, it is true, a predicate. But predication in this case signifies a different relation from that just considered; it reveals the genus inherent in the subject and the subject’s essential character, whereas whiteness is predicated of a thing in the sense of being present in the thing. Enneads: VI I
The properties adduced may indeed be allowed to distinguish Substance from the other Existents. They afford a means of grouping SUBSTANCES together and calling them by a common name. They do not however establish the unity of a genus, and they do not bring to light the concept and the nature of Substance. Enneads: VI I
Are we then to consider numbers, and numbers only, as constituting the category of Quantity? If we mean numbers in themselves, they are SUBSTANCES, for the very good reason that they exist independently. If we mean numbers displayed in the objects participant in number, the numbers which give the count of the objects – ten horses or ten oxen, and not ten units – then we have a paradoxical result: first, the numbers in themselves, it would appear, are SUBSTANCES but the numbers in objects are not; and secondly, the numbers inhere in the objects as measures (of extension or weight), yet as standing outside the objects they have no measuring power, as do rulers and scales. If however their existence is independent, and they do not inhere in the objects, but are simply called in for the purpose of measurement, the objects will be quantities only to the extent of participating in Quantity. Enneads: VI I
We have however to enquire in what sense the abstract numbers are SUBSTANCES. Can it be that they are also in a manner quantitative? Into whatever category they fall, the other numbers (those inherent in objects) can have nothing in common with them but the name. 5>Speech, time, motion – in what sense are these quantities? Let us begin with speech. It is subject to measurement, but only in so far as it is sound; it is not a quantity in its essential nature, which nature is that it be significant, as noun and verb are significant. The air is its Matter, as it is Matter to verb and noun, the components of speech. Enneads: VI I
It need hardly be said that we are not to affirm Relation where one thing is simply an attribute of another, as a habit is an attribute of a soul or of a body; it is not Relation when a soul belongs to this individual or dwells in that body. Relation enters only when the actuality of the relationships is derived from no other source than Relation itself; the actuality must be, not that which is characteristic of the SUBSTANCES in question, but that which is specifically called relative. Thus double with its correlative, half gives actuality neither to two yards’ length or the number two, nor to one yard’s length or the number one; what happens is that, when these quantities are viewed in their relation, they are found to be not merely two and one respectively, but to produce the assertion and to exhibit the fact of standing one to the other in the condition of double and half. Out of the objects in a certain conjunction this condition of being double and half has issued as something distinct from either; double and half have emerged as correlatives, and their being is precisely this of mutual dependence; the double exists by its superiority over the half, and the half by its inferiority; there is no priority to distinguish double from half; they arise simultaneously. Enneads: VI I
What then will be the common ground in habit, disposition, passive quality, figure, shape? In light, thick and lean? If we hold this common ground to be a power adapting itself to the forms of habits, dispositions and physical capacities, a power which gives the possessor whatever capacities he has, we have no plausible explanation of incapacities. Besides, how are figure and the shape of a given thing to be regarded as a power? Moreover, at this, Being will have no power qua Being but only when Quality has been added to it; and the activities of those SUBSTANCES which are activities in the highest degree, will be traceable to Quality, although they are autonomous and owe their essential character to powers wholly their own! Enneads: VI I
Perhaps, however, qualities are conditioned by powers which are posterior to the SUBSTANCES as such (and so do not interfere with their essential activities). Boxing, for example, is not a power of man qua man; reasoning is: therefore reasoning, on this hypothesis, is not quality but a natural possession of the mature human being; it therefore is called a quality only by analogy. Thus, Quality is a power which adds the property of being qualia to SUBSTANCES already existent. Enneads: VI I
The differences distinguishing SUBSTANCES from each other are called qualities only by analogy; they are, more strictly, Acts and Reason-Principles, or parts of Reason-Principles, and though they may appear merely to qualify the substance, they in fact indicate its essence. Enneads: VI I
If however Possession is not to be predicated of Quality because Quality stands recognised as a category, nor of Quantity because the category of Quantity has been received, nor of parts because they have been assigned to the category of Substance, why should we predicate Possession of weapons, when they too are comprised in the accepted category of Substance? Shoes and weapons are clearly SUBSTANCES. Enneads: VI I
Now in the case of composite SUBSTANCES – those constituted from diverse elements – number and qualities provide a means of differentiation: the qualities may be detached from the common core around which they are found to group themselves. But in the primary genera there is no distinction to be drawn between simples and composites; the difference is between simples and those entities which complete not a particular substance but Substance as such. A particular substance may very well receive completion from Quality, for though it already has Substance before the accession of Quality, its particular character is external to Substance. But in Substance itself all the elements are substantial. Enneads VI,2,
Nevertheless, we ventured to assert elsewhere that while the complements of Substance are only by analogy called qualities, yet accessions of external origin and subsequent to Substance are really qualities; that, further, the properties which inhere in SUBSTANCES are their activities (Acts), while those which are subsequent are merely modifications (or Passions): we now affirm that the attributes of the particular substance are never complementary to Substance (as such); an accession of Substance does not come to the substance of man qua man; he is, on the contrary, Substance in a higher degree before he arrives at differentiation, just as he is already “living being” before he passes into the rational species. Enneads VI,2,
Matter will be found common to all SUBSTANCES, not however as a genus, since it has no differentiae – unless indeed differentiae be ascribed to it on the ground of its taking such various forms as fire and air. Enneads VI,3,
We may, also, restrict Substance to the Composite. Matter and Form then cease to be SUBSTANCES. If they are Substance equally with the Composite, it remains to enquire what there is common to all three. Enneads VI,3,
The “mere predicates” fall under the category of Relation: such are cause and element. The accidents included in the composite SUBSTANCES ire found to be either Quality or Quantity; those which are inclusive are of the nature of Space and Time. Activities and experiences comprise Motions; consequents Space and Time, which are consequents respectively of the Composites and of Motion. Enneads VI,3,
The division into elements must, in short, be abandoned, especially in regard to Sensible Substance, known necessarily by sense rather than by reason. We must no longer look for help in constituent parts, since such parts will not be SUBSTANCES, or at any rate not sensible SUBSTANCES. Enneads VI,3,
Our plan must be to apprehend what is constant in stone, earth, water and the entities which they compose – the vegetal and animal forms, considered purely as sensibles – and to confine this constant within a single genus. Neither Matter nor Form will thus be overlooked, for Sensible Substance comports them; fire and earth and the two intermediaries consist of Matter and Form, while composite things are actually many SUBSTANCES in one. They all, moreover, have that common property which distinguishes them from other things: serving as subjects to these others, they are never themselves present in a subject nor predicated of any other thing. Similarly, all the characteristics which we have ascribed to Substance find a place in this classification. Enneads VI,3,
But Sensible Substance is never found apart from magnitude and quality: how then do we proceed to separate these accidents? If we subtract them – magnitude, figure, colour, dryness, moistness – what is there left to be regarded as Substance itself? All the SUBSTANCES under consideration are, of course, qualified. Enneads VI,3,
Another method of division is possible: SUBSTANCES may be classed as hot-dry, dry-cold, cold-moist, or however we choose to make the coupling. We may then proceed to the combination and blending of these couples, either halting at that point and going no further than the compound, or else subdividing by habitation – on the earth, in the earth – or by form and by the differences exhibited by living beings, not qua living, but in their bodies viewed as instruments of life. Enneads VI,3,
It may be urged that the triangle is essentially a particular shape. Then what prevents our ranking the sphere also as a quality? To proceed on these lines would lead us to the conclusion that geometry is concerned not with magnitudes but with Quality. But this conclusion is untenable; geometry is the study of magnitudes. The differences of magnitudes do not eliminate the existence of magnitudes as such, any more than the differences of SUBSTANCES annihilate the SUBSTANCES themselves. Enneads VI,3,
Here a difficulty may be raised: we divide the varieties of Substance and their functions and activities, fair or foul or indeed of any kind whatsoever, on the basis of Quality, Quantity rarely, if ever, entering into the differences which produce species; Quantity, again, we divide in accordance with qualities of its own: how then are we to divide Quality itself into species? what differences are we to employ, and from what genus shall we take them? To take them from Quality itself would be no less absurd than setting up SUBSTANCES as differences of SUBSTANCES. 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.
