(46) Timaeus: the causes which belong to the Intelligent Nature, and put second all such as are of the class of things which are moved by others, and themselves, in turn, move others because they cannot help it. And we also must act likewise. We must declare both kinds of Causes, but keep distinct those which, with the aid of thought, are artificers of things fair and good, and all those which are devoid of intelligence and produce always accidental and irregular effects. Now regarding the auxiliary causes which have helped the eyes to acquire the power which they now possess, let this statement suffice. Next we must declare the most important

(1) In the two orders of things- those whose existence is that of process and those in whom it is Authentic Being- there is a variety of possible relation to Cause.

Cause might conceivably underly all the entities in both orders or none in either. It might underly some, only, in each order, the others being causeless. It might, again, underly the Realm of Process universally while in the Realm of Authentic Existence some things were caused, others not, or all were causeless. Conceivably, on the other hand, the Authentic Existents are all caused while in the Realm of Process some things are caused and others not, or all are causeless.

Now, to begin with the Eternal Existents:

The Firsts among these, by the fact that they are Firsts, cannot be referred to outside Causes; but all such as depend upon those Firsts may be admitted to derive their Being from them.

And in all cases the Act may be referred to the Essence , for their Essence consists, precisely, in giving forth an appropriate Act.

As for Things of Process- or for Eternal Existents whose Act is not eternally invariable- we must hold that these are due to Cause; Causelessness is quite inadmissible; we can make no place here for unwarranted "slantings," for sudden movement of bodies apart from any initiating power, for precipitate spurts in a soul with nothing to drive it into the new course of action. Such causelessness would bind the Soul under an even sterner compulsion, no longer master of itself, but at the mercy of movements apart from will and cause. Something willed- within itself or without- something desired, must lead it to action; without motive it can have no motion.

On the assumption that all happens by Cause, it is easy to discover the nearest determinants of any particular act or state and to trace it plainly to them.

The cause of a visit to the centre of affairs will be that one thinks it necessary to see some person or to receive a debt, or, in a word, that one has some definite motive or impulse confirmed by a judgement of expediency. Sometimes a condition may be referred to the arts, the recovery of health for instance to medical science and the doctor. Wealth has for its cause the discovery of a treasure or the receipt of a gift, or the earning of money by manual or intellectual labour. The child is traced to the father as its Cause and perhaps to a chain of favourable outside circumstances such as a particular diet or, more immediately, a special organic aptitude or a wife apt to childbirth.

And the general cause of all is Nature.

(31) The Cause of things good is One. If the Evil is contrary to the Good, the many causes of the Evil, certainly those productive of things evil, are not principles and powers, but want of power, and want of strength, and a mixing of things dissimilar without proportion. Neither are things evil unmoved, and always in the same condition, but endless and undefined, and borne along in different things, and those endless. The Good will be beginning and end of all, even things evil, for, for the sake of the Good, are all things, both those that are good, and those that are contrary. For we do even these as desiring the Good (for no one does what he does with a view to the Evil), wherefore the Evil has not a subsistence, but a parasitical subsistence, coming into being for the sake of the Good, and not of itself.

(2) Thus we have even here the means of knowing the nature of the Intellectual-Principle, though, seeing it more closely than anything else, we still see it at less than its worth. We know that it exists but its cause we do not see, or, if we do, we see that cause as something apart. We see a man- or an eye, if you like- but this is an image or part of an image; what is in that Principle is at once Man and the reason of his being; for There man- or eye- must be, itself, an intellective thing and a cause of its being; it could not exist at all unless it were that cause, whereas here, everything partial is separate and so is the cause of each. In the Intellectual, all is at one so that the thing is identical with the cause.

Even here the thing and its cause are often identical- an eclipse furnishes an example- what then is there to prevent other things too being identical with their cause and this cause being the essence of the thing? It must be so; and by this search after the cause the thing's essence is reached, for the essence of a thing is its cause. I am not here saying that the informing Idea is the cause of the thing- though this is true- but that the Idea itself, unfolded, reveals the cause inherent in it.

A thing of inactivity, even though alive, cannot include its own cause; but where could a Forming-Idea, a member of the Intellectual-Principle, turn in quest of its cause? We may be answered "In the Intellectual-Principle"; but the two are not distinct; the Idea is the Intellectual-Principle; and if that Principle must contain the Ideas complete, their cause must be contained in them. The Intellectual-Principle itself contains every cause of the things of its content; but these of its content are identically Intellectual-Principle, each of them Intellectual-Principle; none of them, thus, can lack its own cause; each springs into being carrying with it the reason of its being. No result of chance, each must rise complete with its cause; it is an integral and so includes the excellence bound up with the cause. This is how all participants in the Idea are put into possession of their cause.

In our universe, a coherent total of multiplicity, the several items are linked each to the other, and by the fact that it is an all every cause is included in it: even in the particular thing the part is discernibly related to the whole, for the parts do not come into being separately and successively but are mutually cause and caused at one and the same moment. Much more in the higher realm must all the singles exist for the whole and each for itself: if then that world is the conjoint reality of all, of an all not chance-ruled and not sectional, the cause There must include the causes: every item must hold, in its very nature, the uncaused possession of its cause; uncaused, independent and standing apart from cause, they must be self-contained, cause and all.

Further, since nothing There is chance-sprung, and the multiplicity in each comprehends the entire content, then the cause of every member can be named; the cause was present from the beginning, inherent, not a cause but a fact of the being; or, rather, cause and manner of being were one. What could an Idea have, as cause, over and above the Intellectual-Principle? It is a thought of that Principle and cannot, at that, be considered as anything but a perfect product. If it is thus perfect we cannot speak of anything in which it is lacking nor cite any reason for such lack. That thing must be present, and we can say why. The why is inherent, therefore, in the entity, that is to say in every thought and activity of the Intellectual-Principle. Take for example the Idea of Man; Man entire is found to contribute to it; he is in that Idea in all his fulness including everything that from the beginning belonged to Man. If Man were not complete There, so that there were something to be added to the Idea, that additional must belong to a derivative; but Man exists from eternity and must therefore be complete; the man born is the derivative.

(3) How then do we go to work?

Let us begin by distinguishing Matter, Form, the Mixture of both, and the Attributes of the Mixture. The Attributes may be subdivided into those which are mere predicates, and those serving also as accidents. The accidents may be either inclusive or included; they may, further, be classified as activities, experiences, consequents.

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.

It may be held that Matter is sufficiently constituted a genus by the fact that the things in which it appears hold it in common, or in that it presents itself as a whole of parts. In this sense Matter will indeed be a genus, though not in the accepted sense of the term. Matter, we may remark, is also a single element, if the element as such is able to constitute a genus.

Further, if to a Form be added the qualification "bound up with, involved in Matter," Matter separates that Form from other Forms: it does not however embrace the whole of Substantial Form .

We may, again, regard Form as the creator of Substance and make the Reason-Principle of Substance dependent upon Form: yet we do not come thereby to an understanding of the nature of Substance.

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.

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.

The first three entities go, as we have discovered, to make a single common genus, the Sensible counterpart of Substance. Then follow in order Relation, Quantity, Quality, Time-during-which, Place-in-which, Motion; though, with Time and Space already included , Time-during-which and Place-in-which become superfluous.

Thus we have five genera, counting the first three entities as one. If the first three are not massed into a unity, the series will be Matter, Form, Composite, Relation, Quantity, Quality, Motion. The last three may, again, be included in Relation, which is capable of bearing this wider extension.

(3) We assert, then, a plurality of Existents, but a plurality not fortuitous and therefore a plurality deriving from a unity.

But even admitting this derivation from a unity- a unity however not predicated of them in respect of their essential being- there is, surely, no reason why each of these Existents, distinct in character from every other, should not in itself stand as a separate genus.

Is, then, this unity external to the genera thus produced, this unity which is their source though it cannot be predicated of them in respect of their essence? it is indeed external; the One is beyond; it cannot, therefore, be included among the geneANSWER: it is the source, while they stand side by side as genera. Yet surely the one must somehow be included ? No: it is the Existents we are investigating, not that which is beyond Existence.

We pass on, then, to consider that which is included, and find to our surprise the cause included with the things it causes: it is surely strange that causes and effects should be brought into the same genus.

But if the cause is included with its effects only in the sense in which a genus is included with its subordinates, the subordinates being of a different order, so that it cannot be predicated of them whether as their genus or in any other relation, these subordinates are obviously themselves genera with subordinates of their own: you may, for example, be the cause of the operation of walking, but the walking is not subordinate to you in the relation of species to genus; and if walking had nothing prior to it as its genus, but had posteriors, then it would be a genus and rank among the Existents.

Perhaps, however, it must be utterly denied that unity is even the cause of other things; they should be considered rather as its parts or elements- if the terms may be allowed,- their totality constituting a single entity which our thinking divides. All unity though it be, it goes by a wonderful power out into everything; it appears as many and becomes many when there is a motion; the fecundity of its nature causes the One to be no longer one, and we, displaying what we call its parts, consider them each as a unity and make them into "genera," unaware of our failure to see the whole at once. We display it, then, in parts, though, unable to restrain their natural tendency to coalesce, we bring these parts together again, resign them to the whole and allow them to become a unity, or rather to be a unity.

All this will become clearer in the light of further consideration- when, that is to say, we have ascertained the number of the genera; for thus we shall also discover their causes. It is not enough to deny; we must advance by dint of thought and comprehension. The way is clear:

(2) But it reasonably follows, according to continuity of alliance, that the medium which begins from the most excellent natures, should proceed to such as are less excellent; but that the medium which primarily produces a contact with the last of things, should also in a certain respect communicate with the natures that transcend it. From these media, also, the completion may be seen of the first and last genera, and this entirely connascent, in a similar manner, in existence, in power, and in energy. As we have, therefore, in these two ways, perfectly completed the division of the four genera, we shall deem it sufficient in the others, to exhibit the extreme peculiarities alone, for the sake of conciseness, and because what remains, i. e. the comprehension of the media, is in a certain respect evident. But the media themselves, as being known from the extremes, we shall omit; making a definition of the extremes in the shortest way, as follows.

(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.

(15) How then do the four genera complete Substance without qualifying it or even particularizing it?

It has been observed that Being is primary, and it is clear that none of the four- Motion, Stability, Difference, Identity- is distinct from it. That this Motion does not produce Quality is doubtless also clear, but a word or two will make it clearer still.

If Motion is the Act of Substance, and Being and the Primaries in general are its Act, then Motion is not an accidental attribute: as the Act of what is necessarily actual , it is no longer to be considered as the complement of Substance but as Substance itself. For this reason, then, it has not been assigned to a posterior class, or referred to Quality, but has been made contemporary with Being.

The truth is not that Being first is and then takes Motion, first is and then acquires Stability: neither Stability nor Motion is a mere modification of Being. Similarly, Identity and Difference are not later additions: Being did not grow into plurality; its very unity was a plurality; but plurality implies Difference, and unity-in-plurality involves Identity.

Substance requires no more than these five constituents; but when we have to turn to the lower sphere, we find other principles giving rise no longer to Substance (as such) but to quantitative Substance and qualitative: these other principles may be regarded as genera but not primary genera.

(69) Timaeus: and to seek the necessary for the sake of the divine, reckoning that without the former it is impossible to discern by themselves alone the divine objects after which we strive, or to apprehend them or in any way partake thereof. Seeing, then, that we have now lying before us and thoroughly sifted—like wood ready for the joiner, —the various kinds of causes, out of which the rest of our account must be woven together, let us once more for a moment revert to our starting-point, and thence proceed rapidly to the point

(7) What, then, are the several entities observable in this plurality?

We have found Substance and life simultaneously present in Soul. Now, this Substance is a common property of Soul, but life, common to all souls, differs in that it is a property of Intellect also.

Having thus introduced Intellect and its life we make a single genus of what is common to all life, namely, Motion. Substance and the Motion, which constitutes the highest life, we must consider as two genera; for even though they form a unity, they are separable to thought which finds their unity not a unity; otherwise, it could not distinguish them.

Observe also how in other things Motion or life is clearly separated from Being- a separation impossible, doubtless, in True Being, but possible in its shadow and namesake. In the portrait of a man much is left out, and above all the essential thing, life: the "Being" of sensible things just such a shadow of True Being, an abstraction from that Being complete which was life in the Archetype; it is because of this incompleteness that we are able in the Sensible world to separate Being from life and life from Being.

Being, then, containing many species, has but one genus. Motion, however, is to be classed as neither a subordinate nor a supplement of Being but as its concomitant; for we have not found Being serving as substrate to Motion. Motion is being Act; neither is separated from the other except in thought; the two natures are one; for Being is inevitably actual, not potential.

No doubt we observe Motion and Being separately, Motion as contained in Being and Being as involved in Motion, and in the individual they may be mutually exclusive; but the dualism is an affirmation of our thought only, and that thought sees either form as a duality within a unity.

Now Motion, thus manifested in conjunction with Being, does not alter Being's nature- unless to complete its essential character- and it does retain for ever its own peculiar nature: at once, then, we are forced to introduce Stability. To reject Stability would be more unreasonable than to reject Motion; for Stability is associated in our thought and conception with Being even more than with Motion; unalterable condition, unchanging mode, single Reason-Principle- these are characteristics of the higher sphere.

Stability, then, may also be taken as a single genus. Obviously distinct from Motion and perhaps even its contrary, that it is also distinct from Being may be shown by many considerations. We may especially observe that if Stability were identical with Being, so also would Motion be, with equal right. Why identity in the case of Stability and not in that of Motion, when Motion is virtually the very life and Act both of Substance and of Absolute Being? However, on the very same principle on which we separated Motion from Being with the understanding that it is the same and not the same- that they are two and yet one- we also separate Stability from Being, holding it, yet, inseparable; it is only a logical separation entailing the inclusion among the Existents of this other genus. To identify Stability with Being, with no difference between them, and to identify Being with Motion, would be to identify Stability with Motion through the mediation of Being, and so to make Motion and Stability one and the same thing.

(79) "The Cause is, that the first four Forms of Nature, are one at Enmity against the other without the Light; and yet they are the Causes of Life."

(8) We cannot indeed escape positing these three, Being, Motion, Stability, once it is the fact that the Intellect discerns them as separates; and if it thinks of them at all, it posits them by that very thinking; if they are thought, they exist. Things whose existence is bound up with Matter have no being in the Intellect: these three principles are however free of Matter; and in that which goes free of Matter to be thought is to be.

We are in the presence of Intellect undefiled. Fix it firmly, but not with the eyes of the body. You are looking upon the hearth of Reality, within it a sleepless light: you see how it holds to itself, and how it puts apart things that were together, how it lives a life that endures and keeps a thought acting not upon any future but upon that which already is, upon an eternal present- a thought self-centred, bearing on nothing outside of itself.

Now in the Act of Intellect there are energy and motion; in its self-intellection Substance and Being. In virtue of its Being it thinks, and it thinks of itself as Being, and of that as Being, upon which it is, so to speak, pivoted. Not that its Act self-directed ranks as Substance, but Being stands as the goal and origin of that Act, the object of its contemplation though not the contemplation itself: and yet this Act too involves Being, which is its motive and its term. By the fact that its Being is actual and not merely potential, Intellect bridges the dualism and abjures separation: it identifies itself with Being and Being with itself.

Being, the most firmly set of all things, that in virtue of which all other things receive Stability, possesses this Stability not as from without but as springing within, as inherent. Stability is the goal of intellection, a Stability which had no beginning, and the state from which intellection was impelled was Stability, though Stability gave it no impulsion; for Motion neither starts from Motion nor ends in Motion. Again, the Form-Idea has Stability, since it is the goal of Intellect: intellection is the Form's Motion.

Thus all the Existents are one, at once Motion and Stability; Motion and Stability are genera all-pervading, and every subsequent is a particular being, a particular stability and a particular motion.

We have caught the radiance of Being, and beheld it in its three manifestations: Being, revealed by the Being within ourselves; the Motion of Being, revealed by the motion within ourselves; and its Stability revealed by ours. We accommodate our being, motion, stability to those , unable however to draw any distinction but finding ourselves in the presence of entities inseparable and, as it were, interfused. We have, however, in a sense, set them a little apart, holding them down and viewing them in isolation; and thus we have observed Being, Stability, Motion- these three, of which each is a unity to itself; in so doing, have we not regarded them as being different from each other? By this posing of three entities, each a unity, we have, surely, found Being to contain Difference.

Again, inasmuch as we restore them to an all-embracing unity, identifying all with unity, do we not see in this amalgamation Identity emerging as a Real Existent?

Thus, in addition to the other three , we are obliged to posit the further two, Identity and Difference, so that we have in all five genera. In so doing, we shall not withhold Identity and Difference from the subsequents of the Intellectual order; the thing of Sense has, it is clear, a particular identity and a particular difference, but Identity and Difference have the generic status independently of the particular.

They will, moreover, be primary genera, because nothing can be predicated of them as denoting their essential nature. Nothing, of course we mean, but Being; but this Being is not their genus, since they cannot be identified with any particular being as such. Similarly, Being will not stand as genus to Motion or Stability, for these also are not its species. Beings comprise not merely what are to be regarded as species of the genus Being, but also participants in Being. On the other hand, Being does not participate in the other four principles as its geneANSWER: they are not prior to Being; they do not even attain to its level.

(2) But to halt at these nearest determinants, not to be willing to penetrate deeper, indicates a sluggish mind, a dullness to all that calls us towards the primal and transcendent causes.

How comes it that the same surface causes produce different results? There is moonshine, and one man steals and the other does not: under the influence of exactly similar surroundings one man falls sick and the other keeps well; an identical set of operations makes one rich and leaves another poor. The differences amongst us in manners, in characters, in success, force us to go still further back.

Men therefore have never been able to rest at the surface causes.

One school postulates material principles, such as atoms; from the movement, from the collisions and combinations of these, it derives the existence and the mode of being of all particular phenomena, supposing that all depends upon how these atoms are agglomerated, how they act, how they are affected; our own impulses and states, even, are supposed to be determined by these principles.

Such teaching, then, obtrudes this compulsion, an atomic Anagke, even upon Real Being. Substitute, for the atoms, any other material entities as principles and the cause of all things, and at once Real Being becomes servile to the determination set up by them.

Others rise to the first-principle of all that exists and from it derive all they tell of a cause penetrating all things, not merely moving all but making each and everything; but they pose this as a fate and a supremely dominating cause; not merely all else that comes into being, but even our own thinking and thoughts would spring from its movement, just as the several members of an animal move not at their own choice but at the dictation of the leading principle which animal life presupposes.

Yet another school fastens on the universal Circuit as embracing all things and producing all by its motion and by the positions and mutual aspect of the planets and fixed stars in whose power of foretelling they find warrant for the belief that this Circuit is the universal determinant.

Finally, there are those that dwell on the interconnection of the causative forces and on their linked descent- every later phenomenon following upon an earlier, one always leading back to others by which it arose and without which it could not be, and the latest always subservient to what went before them- but this is obviously to bring in fate by another path. This school may be fairly distinguished into two branches; a section which makes all depend upon some one principle and a section which ignores such a unity.

Of this last opinion we will have something to say, but for the moment we will deal with the former, taking the others in their turn.

(28) Timaeus: and things sensible, being apprehensible by opinion with the aid of sensation, come into existence, as we saw, and are generated. And that which has come into existence must necessarily, as we say, have come into existence by reason of some Cause. Now to discover the Maker and Father of this Universe were a task indeed; and having discovered Him, to declare Him unto all men were a thing impossible. However, let us return and inquire further concerning the Cosmos,—after which of the Models did its Architect construct it?

(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.
