(18) Things seen have as their property manifestation, action, inertia. They form the basis of the elements and the sense-powers. They make for experience and for liberation.

(14) Every object has its characteristics which are already quiescent, those which are active, and those which are not yet definable.

(3) 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.

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.

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.

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.

These considerations are sufficient for our purpose: let us now proceed to investigate the nature of Quantity.

(23) A first principle is that the knowing of sensible objects is an act of the soul, or of the living conjoint, becoming aware of the quality of certain corporeal entities, and appropriating the ideas present in them.

This apprehension must belong either to the soul isolated, self-acting, or to soul in conjunction with some other entity.

Isolated, self-acting, how is it possible? Self-acting, it has knowledge of its own content, and this is not perception but intellection: if it is also to know things outside itself it can grasp them only in one of two ways: either it must assimilate itself to the external objects, or it must enter into relations with something that has been so assimilated.

Now as long as it remains self-centred it cannot assimilate: a single point cannot assimilate itself to an external line: even line cannot adapt itself to line in another order, line of the intellectual to line of the sensible, just as fire of the intellectual and man of the intellectual remain distinct from fire and man of the sensible. Even Nature, the soul-phase which brings man into being, does not come to identity with the man it shapes and informs: it has the faculty of dealing with the sensible, but it remains isolated, and, its task done, ignores all but the intellectual as it is itself ignored by the sensible and utterly without means of grasping it.

Suppose something visible lying at a distance: the soul sees it; now, admitting to the full that at first only the pure idea of the thing is seized- a total without discerned part- yet in the end it becomes to the seeing soul an object whose complete detail of colour and form is known: this shows that there is something more here than the outlying thing and the soul; for the soul is immune from experience; there must be a third, something not thus exempt; and it is this intermediate that accepts the impressions of shape and the like.

This intermediate must be able to assume the modifications of the material object so as to be an exact reproduction of its states, and it must be of the one elemental-stuff: it, thus, will exhibit the condition which the higher principle is to perceive; and the condition must be such as to preserve something of the originating object, and yet not be identical with it: the essential vehicle of knowledge is an intermediary which, as it stands between the soul and the originating object, will, similarly, present a condition midway between the two spheres, of sense and the intellectual-linking the extremes, receiving from one side to exhibit to the other, in virtue of being able to assimilate itself to each. As an instrument by which something is to receive knowledge, it cannot be identical with either the knower or the known: but it must be apt to likeness with both- akin to the external object by its power of being affected, and to the internal, the knower, by the fact that the modification it takes becomes an idea.

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.

The organ must be either the body entire or some member set apart for a particular function; thus touch for one, vision for another. The tools of craftsmanship will be seen to be intermediaries between the judging worker and the judged object, disclosing to the experimenter the particular character of the matter under investigation: thus a ruler, representing at once the straightness which is in the mind and the straightness of a plank, is used as an intermediary by which the operator proves his work.

Some questions of detail remain for consideration elsewhere: Is it necessary that the object upon which judgement or perception is to take place should be in contact with the organ of perception, or can the process occur across space upon an object at a distance? Thus, is the heat of a fire really at a distance from the flesh it warms, the intermediate space remaining unmodified; is it possible to see colour over a sheer blank intervening between the colour and the eye, the organ of vision reaching to its object by its own power?

For the moment we have one certainty, that perception of things of sense belongs to the embodied soul and takes place through the body.

(15) The paths of material things and of states of consciousness are distinct, as is manifest from the fact that the same object may produce different impressions in different minds.

(43) When the object dwells in the mind, clear of memory-pictures, uncoloured by the mind, as a pure luminous idea, this is perception without exterior or consideration.

(25) There are those who lay down four categories and make a fourfold division into Substrates, Qualities, States, and Relative States, and find in these a common Something, and so include everything in one genus.

Against this theory there is much to be urged, but particularly against this posing of a common Something and a single all-embracing genus. This Something, it may be submitted, is unintelligible to themselves, is indefinable, and does not account either for bodies or for the bodiless. Moreover, no room is left for a differentia by which this Something may be distinguished. Besides, this common Something is either existent or non-existent: if existent, it must be one or other of its species;- if non-existent, the existent is classed under the non-existent. But the objections are countless; we must leave them for the present and consider the several heads of the division.

To the first genus are assigned Substrates, including Matter, to which is given a priority over the others; so that what is ranked as the first principle comes under the same head with things which must be posterior to it since it is their principle.

First, then: the prior is made homogeneous with the subsequent. Now this is impossible: in this relation the subsequent owes its existence to the prior, whereas among things belonging to one same genus each must have, essentially, the equality implied by the genus; for the very meaning of genus is to be predicated of the species in respect of their essential character. And that Matter is the basic source of all the rest of things, this school, we may suppose, would hardly deny.

Secondly: since they treat the Substrate as one thing, they do not enumerate the Existents; they look instead for principles of the Existents. There is however a difference between speaking of the actual Existents and of their principles.

If Matter is taken to be the only Existent, and all other things as modifications of Matter, it is not legitimate to set up a single genus to embrace both the Existent and the other things; consistency requires that Being be distinguished from its modifications and that these modifications be duly classified.

Even the distinction which this theory makes between Substrates and the rest of things is questionable. The Substrate is one thing and admits of no differentia- except perhaps in so far as it is split up like one mass into its various parts; and yet not even so, since the notion of Being implies continuity: it would be better, therefore, to speak of the Substrate, in the singular.

(8) For my part I am satisfied that anyone considering the mode in which Matter participates in the Ideas will be ready enough to accept this tenet of omnipresence in identity, no longer rejecting it as incredible or even difficult. This because it seems reasonable and imperative to dismiss any notion of the Ideas lying apart with Matter illumined from them as from somewhere above- a meaningless conception, for what have distance and separation to do here?

This participation cannot be thought of as elusive or very perplexing; on the contrary, it is obvious, accessible in many examples.

Note, however, that when we sometimes speak of the Ideas illuminating Matter this is not to suggest the mode in which material light pours down on a material object; we use the phrase in the sense only that, the material being image while the Ideas are archetypes, the two orders are distinguished somewhat in the manner of illuminant and illuminated. But it is time to be more exact.

We do not mean that the Idea, locally separate, shows itself in Matter like a reflection in water; the Matter touches the Idea at every point, though not in a physical contact, and, by dint of neighbourhood- nothing to keep them apart- is able to absorb thence all that lies within its capacity, the Idea itself not penetrating, not approaching, the Matter, but remaining self-locked.

We take it, then, that the Idea, say of Fire- for we had best deal with Matter as underlying the elements- is not in the Matter. The Ideal Fire, then, remaining apart, produces the form of fire throughout the entire enfired mass. Now let us suppose- and the same method will apply to all the so-called elements- that this Fire in its first material manifestation is a multiple mass. That single Fire is seen producing an image of itself in all the sensible fires; yet it is not spatially separate; it does not, then, produce that image in the manner of our visible light; for in that case all this sensible fire, supposing that it were a whole of parts , must have generated spatial positions out of itself, since the Idea or Form remains in a non-spatial world; for a principle thus pluralized must first have departed from its own character in order to be present in that many and participate many times in the one same Form.

The Idea, impartible, gives nothing of itself to the Matter; its unbreaking unity, however, does not prevent it shaping that multiple by its own unity and being present to the entirety of the multiple, bringing it to pattern not by acting part upon part but by presence entire to the object entire. It would be absurd to introduce a multitude of Ideas of Fire, each several fire being shaped by a particular idea; the Ideas of fire would be infinite. Besides, how would these resultant fires be distinct, when fire is a continuous unity? and if we apply yet another fire to certain matter and produce a greater fire, then the same Idea must be allowed to have functioned in the same way in the new matter as in the old; obviously there is no other Idea.

(3) But it leaves that conjunction; it cannot suffer that unity; it falls in love with its own powers and possessions, and desires to stand apart; it leans outward so to speak: then, it appears to acquire a memory of itself.

In this self-memory a distinction is to be made; the memory dealing with the Intellectual Realm upbears the soul, not to fall; the memory of things here bears it downwards to this universe; the intermediate memory dealing with the heavenly sphere holds it there too; and, in all its memory, the thing it has in mind it is and grows to; for this bearing-in-mind must be either intuition or representation by image: and the imaging in the case of the is not a taking in of something but is vision and condition- so much so, that, in its very sense- sight, it is the lower in the degree in which it penetrates the object. Since its possession of the total of things is not primal but secondary, it does not become all things perfectly ; it is of the boundary order, situated between two regions, and has tendency to both.

(4) What, then, we have to ask, is the constant element in the first three entities? What is it that identifies them with their inherent Substance?

Is it the capacity to serve as a base? But Matter, we maintain, serves as the base and seat of Form: Form, thus, will be excluded from the category of Substance. Again, the Composite is the base and seat of attributes: hence, Form combined with Matter will be the basic ground of Composites, or at any rate of all posteriors of the Composite- Quantity, Quality, Motion, and the rest.

But perhaps we may think Substance validly defined as that which is not predicated of anything else. White and black are predicated of an object having one or other of these qualities; double presupposes something distinct from itself- we refer not to the half, but to the length of wood of which doubleness is affirmed. father qua father is a predicate; knowledge is predicated of the subject in whom the knowledge exists; space is the limit of something, time the measure of something. Fire, on the other hand, is predicated of nothing; wood as such is predicated of nothing; and so with man, Socrates, and the composite substance in general.

Equally the Substantial Form is never a predicate, since it never acts as a modification of anything. Form is not an attribute of Matter hence, is not predicable of Matter it is simply a constituent of the Couplement. On the other hand, the Form of a man is not different from the man himself .

Matter, similarly, is part of a whole, and belongs to something else only as to a whole and not as to a separate thing of which it is predicated. White, on the contrary, essentially belongs to something distinct from itself.

We conclude that nothing belonging to something else and predicated of it can be Substance. Substance is that which belongs essentially to itself, or, in so far as it is a part of the differentiated object, serves only to complete the Composite. Each or either part of the Composite belongs to itself, and is only affirmed of the Composite in a special sense: only qua part of the whole is it predicated of something else; qua individual it is never in its essential nature predicated of an external.

It may be claimed as a common element in Matter, Form and the Couplement that they are all substrates. But the mode in which Matter is the substrate of Form is different from that in which Form and the Couplement are substrates of their modifications.

And is it strictly true to say that Matter is the substrate of Form? Form is rather the completion which Matter's nature as pure potentiality demands.

Moreover, Form cannot be said to reside in Matter . When one thing combines with another to form a unity, the one does not reside in the other; both alike are substrates of a third: thus, Man and a man are substrates of their experiences, and are prior to their activities and consequents.

Substance, then, is that from which all other things proceed and to which they owe their existence; it is the centre of passivity and the source of action.

(23) The psychic nature, taking on the colour of the Seer and of things seen, leads to the perception of all objects.

(28) We have already indicated that Activity and Passivity are to be regarded as motions, and that it is possible to distinguish absolute motions, actions, passions.

As for the remaining so-called genera, we have shown that they are reducible to those which we have posited.

With regard to the relative, we have maintained that Relation belongs to one object as compared with another, that the two objects coexist simultaneously, and that Relation is found wherever a substance is in such a condition as to produce it; not that the substance is a relative, except in so far as it constitutes part of a whole- a hand, for example, or head or cause or principle or element.

We may also adopt the ancient division of relatives into creative principles, measures, excesses and deficiencies, and those which in general separate objects on the basis of similarities and differences.

Our investigation into the kinds of Being is now complete.

(10) In view of all this we must now work back from the items to the unit, and consider the entire scheme as one enduring thing.

We ascend from air, light, sun- or, moon and light and sun- in detail, to these things as constituting a total- though a total of degrees, primary, secondary, tertiary. Thence we come to the Soul, always the one undiscriminated entity. At this point in our survey we have before us the over-world and all that follows upon it. That suite we take to be the very last effect that has penetrated to its furthest reach.

Our knowledge of the first is gained from the ultimate of all, from the very shadow cast by the fire, because this ultimate itself receives its share of the general light, something of the nature of the Forming-Idea hovering over the outcast that at first lay in blank obscurity. It is brought under the scheme of reason by the efficacy of soul whose entire extension latently holds this rationalizing power. As we know, the Reason-Principles carried in animal seed fashion and shape living beings into so many universes in the small. For whatsoever touches soul is moulded to the nature of soul's own Real-Being.

We are not to think that the Soul acts upon the object by conformity to any external judgement; there is no pause for willing or planning: any such procedure would not be an act of sheer nature, but one of applied art: but art is of later origin than soul; it is an imitator, producing dim and feeble copies- toys, things of no great worth- and it is dependent upon all sorts of mechanism by which alone its images can be produced. The soul, on the contrary, is sovereign over material things by might of Real-Being; their quality is determined by its lead, and those elementary things cannot stand against its will. On the later level, things are hindered one by the other, and thus often fall short of the characteristic shape at which their unextended Reason-Principle must be aiming; in that other world the entire shape comes from soul, and all that is produced takes and keeps its appointed place in a unity, so that the engendered thing, without labour as without clash, becomes all that it should be. In that world the soul has elaborated its creation, the images of the gods, dwellings for men, each existing to some peculiar purpose.

Soul could produce none but the things which truly represent its powers: fire produces warmth; another source produces cold; soul has a double efficacy, its act within itself, and its act from within outwards towards the new production.

In soulless entities, the outgo remains dormant, and any efficiency they have is to bring to their own likeness whatever is amenable to their act. All existence has this tendency to bring other things to likeness; but the soul has the distinction of possessing at once an action of conscious attention within itself, and an action towards the outer. It has thus the function of giving life to all that does not live by prior right, and the life it gives is commensurate with its own; that is to say, living in reason, it communicates reason to the body- an image of the reason within itself, just as the life given to the body is an image of Real-Being- and it bestows, also, upon that material the appropriate shapes of which it contains the Reason-Forms.

The content of the creative soul includes the Ideal shapes of gods and of all else: and hence it is that the kosmos contains all.

(23) As for Possession, if the term is used comprehensively, why are not all its modes to be brought under one category? Possession, thus, would include the quantum as possessing magnitude, the quale as possessing colour; it would include fatherhood and the complementary relationships, since the father possesses the son and the son possesses the father: in short, it would include all belongings.

If, on the contrary, the category of Possession comprises only the things of the body, such as weapons and shoes, we first ask why this should be so, and why their possession produces a single category, while burning, cutting, burying or casting them out do not give another or others. If it is because these things are carried on the person, then one's mantle lying on a couch will come under a different category from that of the mantle covering the person. If the ownership of possession suffices, then clearly one must refer to the one category of Possession all objects identified by being possessed, every case in which possession can be established; the character of the possessed object will make no difference.

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.

How, further, is "He possesses weapons," signifying as it does that the action of arming has been performed by a subject, to be regarded as an entirely simple notion, assignable to a single category?

Again, is Possession to be restricted to an animate possessor, or does it hold good even of a statue as possessing the objects above mentioned? The animate and inanimate seem to possess in different ways, and the term is perhaps equivocal. Similarly, "standing" has not the same connotation as applied to the animate and the inanimate.

Besides, how can it be reasonable for what is found only in a limited number of cases to form a distinct generic category?

(8) 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.

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.

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.

There is, however, something in relation to which whatever turns Substance into qualified Substance is accidental: thus, the whole of fire is not Substance, but only a part of it- if the term "part" be allowed.

What then can this "part" be? Matter may be suggested. But are we actually to maintain that the particular sensible substance consists of a conglomeration of qualities and Matter, while Sensible Substance as a whole is merely the sum of these coagulations in the uniform Matter, each one separately forming a quale or a quantum or else a thing of many qualities? Is it true to say that everything whose absence leaves subsistence incomplete is a part of the particular substance, while all that is accidental to the substance already existent takes independent rank and is not submerged in the mixture which constitutes this so-called substance?

I decline to allow that whatever combines in this way with anything else is Substance if it helps to produce a single mass having quantity and quality, whereas taken by itself and divorced from this complementary function it is a quality: not everything which composes the amalgam is Substance, but only the amalgam as a whole.

And let no one take exception on the ground that we produce Sensible Substance from non-substances. The whole amalgam itself is not True Substance; it is merely an imitation of that True Substance which has Being apart from its concomitants, these indeed being derived from it as the possessor of True Being. In the lower realm the case is different: the underlying ground is sterile, and from its inability to produce fails to attain to the status of Being; it remains a shadow, and on this shadow is traced a sketch- the world of Appearance.

(17) An object is perceived, or not perceived, according as the mind is, or is not, tinged with the colour of the object.

(13) It cannot reasonably be thought that the notion of unity is derived from the object since this is physical- man, animal, even stone, a presentation of that order is something very different from unity ; if that presentation were unity, the mind could never affirm unity unless of that given thing, man, for example.

Then again, just as in the case of "On the right" or other such affirmation of relation, the mind does not affirm in some caprice but from observation of contrasted position, so here it affirms unity in virtue of perceiving something real; assuredly the assertion of unity is not a bare attitude towards something non-existent. It is not enough that a thing be alone and be itself and not something else: and that very "something else" tells of another unity. Besides Otherness and Difference are later; unless the mind has first rested upon unity it cannot affirm Otherness or Difference; when it affirms Aloneness it affirms unity-with-aloneness; thus unity is presupposed in Aloneness.

Besides, that in us which asserts unity of some object is first a unity, itself; and the object is a unity before any outside affirmation or conception.

A thing must be either one thing or more than one, manifold: and if there is to be a manifold there must be a precedent unity. To talk of a manifold is to talk of what has something added to unity; to think of an army is to think of a multitude under arms and brought to unity. In refusing to allow the manifold to remain manifold, the mind makes the truth clear; it draws a separate many into one, either supplying a unity not present or keen to perceive the unity brought about by the ordering of the parts; in an army, even, the unity is not a fiction but as real as that of a building erected from many stones, though of course the unity of the house is more compact.

If, then, unity is more pronounced in the continuous, and more again where there is no separation by part, this is clearly because there exists, in real existence, something which is a Nature or Principle of Unity. There cannot be a greater and less in the non-existent: as we predicate Substance of everything in sense, but predicate it also of the Intellectual order and more strictly there- since we hold that the greater and more sovereign substantiality belongs to the Real Beings and that Being is more marked in Substance, even sensible Substance, than in the other Kinds- so, finding unity to exhibit degree of more and less, differing in sense-things as well as in the Intellectual, we must similarly admit that Unity exists under all forms though still by reference, only, to that primal Unity.

As Substance and Real Being, despite the participation of the sensible, are still of the Intellectual and not the sensible order, so too the unity observed present in things of sense by participation remains still an Intellectual and to be grasped by an Intellectual Act. The mind, from a thing present to it, comes to knowledge of something else, a thing not presented; that is, it has a prior knowledge. By this prior knowledge it recognises Being in a particular being; similarly when a thing is one it can affirm unity as it can affirm also duality and multiplicity.

It is impossible to name or conceive anything not making one or two or some number; equally impossible that the thing should not exist without which nothing can possibly be named or conceived; impossible to deny the reality of that whose existence is a necessary condition of naming or affirming anything; what is a first need, universally, to the formation of every concept and every proposition must exist before reasoning and thinking; only as an existent can it be cited to account for the stirring of thought. If Unity is necessary to the substantial existence of all that really is- and nothing exists which is not one- Unity must precede Reality and be its author. It is therefore, an existent Unity, not an existent that develops Unity; considered as Being-with-Unity it would be a manifold, whereas in the pure Unity there is no Being save in so far as Unity attends to producing it. As regards the word "This," it is nat a bare word; it affirms an indicated existence without using the name, it tells of a certain presence, whether a substance or some other existent; any This must be significant; it is no attitude of the mind applying itself to a non-existent; the This shows a thing present, as much as if we used the strict name of the object.

(2) those things that are difficult to distinguish you might distinguish, and those things that are unknown to the multitude you might know, and that you might be restored to that which is yours, which was already intact and so needs no restoration.

(1) We undertook to discuss the question whether sight is possible in the absence of any intervening medium, such as air or some other form of what is known as transparent body: this is the time and place.

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.

The knowledge, then, is realized by means of bodily organs: through these, which are almost of one growth with it, being at least its continuations, it comes into something like unity with the alien, since this mutual approach brings about a certain degree of identity .

Admitting, then, that some contact with an object is necessary for knowing it, the question of a medium falls to the ground in the case of things identified by any form of touch; but in the case of sight- we leave hearing over for the present- we are still in doubt; is there need of some bodily substance between the eye and the illumined object?

No: such an intervening material may be a favouring circumstance, but essentially it adds nothing to seeing power. ! Dense bodies, such as clay, actually prevent sight; the less material the intervening substance is, the more clearly we see; the intervening substance, then, is a hindrance, or, if not that, at least not a help.

It will be objected that vision implies that whatever intervenes between seen and seer must first experience the object and be, as it were, shaped to it; we will be reminded that anyone facing to the object from the side opposite to ourselves sees it equally; we will be asked to deduce that if all the space intervening between seen and seer did not carry the impression of the object we could not receive it.

But all the need is met when the impression reaches that which is adapted to receive it; there is no need for the intervening space to be impressed. If it is, the impression will be of quite another order: the rod between the fisher's hand and the torpedo fish is not affected in the same way as the hand that feels the shock. And yet there too, if rod and line did not intervene, the hand would not be affected- though even that may be questioned, since after all the fisherman, we are told, is numbed if the torpedo merely lies in his net.

The whole matter seems to bring us back to that sympathy of which we have treated. If a certain thing is of a nature to be sympathetically affected by another in virtue of some similitude between them, then anything intervening, not sharing in that similitude, will not be affected, or at least not similarly. If this be so, anything naturally disposed to be affected will take the impression more vividly in the absence of intervening substance, even of some substance capable, itself, of being affected.

(1) Philosophy at a very early stage investigated the number and character of the Existents. Various theories resulted: some declared for one Existent, others for a finite number, others again for an infinite number, while as regards the nature of the Existents- one, numerically finite, or numerically infinite- there was a similar disagreement. These theories, in so far as they have been adequately examined by later workers, may be passed over here; our attention must be directed upon the results of those whose examination has led them to posit on their awn account certain well-defined genera.

These thinkers rejected pure unity on the ground of the plurality observed even in the Intellectual world; they rejected an infinite number as not reconcilable with the facts and as defying knowledge: considering the foundations of being to be "genera" rather than elements strictly so called, they concluded for a finite number. Of these "genera" some found ten, others less, others no doubt more.

But here again there is a divergence of views. To some the genera are first-principles; to others they indicate only a generic classification of the Existents themselves.

Let us begin with the well-known tenfold division of the Existents, and consider whether we are to understand ten genera ranged under the common name of Being, or ten categories. That the term Being has not the same sense in all ten is rightly maintained.

But a graver problem confronts us at the outset: Are the ten found alike in the Intellectual and in the Sensible realms? Or are all found in the Sensible and some only in the Intellectual? All in the Intellectual and some in the Sensible is manifestly impossible.

At this point it would be natural to investigate which of the ten belong to both spheres, and whether the Existents of the Intellectual are to be ranged under one and the same genus with the Existents in the Sensible, or whether the term "Existence" is equivocal as applied to both realms. If the equivocation exists, the number of genera will be increased: if there is no equivocation, it is strange to find the one same "Existence" applying to the primary and to the derivative Existents when there is no common genus embracing both primal and secondary.

These thinkers are however not considering the Intellectual realm in their division, which was not intended to cover all the Existents; the Supreme they overlooked.
