(2) But, as your question now stands, with respect to the peculiarities by which these genera are separated, you alone speak of the peculiarities of energies. Hence you inquire concerning the difference in the last things pertaining to them; but you leave uninvestigated such things as are first, and most honourable in them, and which are the elements of their difference. In the same place, also, something is added concerning “ efficacious and passive motions ,” which is a division by no means adapted to the difference of the more excellent genera. For the contrariety of action and passion is not inherent in any one of them; but their energies are unrestrained, immutable, and without habitude to their opposites. Hence, neither must we admit in them motions of such a kind as arise from action and passion. For neither do we admit in the soul a self-motion, which consists of the mover and that which is moved; but we conceive that it is a certain simple essential motion, subsisting from itself, and not possessing a habitude to another thing, and exempt from acting on, and suffering from, itself. Who, therefore, can endure that the peculiarities of the genera superior to the soul, should be distinguished according to active or passive motions?

(436) rather say that one part of him is in motion while another is at rest. Very true. And suppose the objector to refine still further, and to draw the nice distinction that not only parts of tops, but whole tops, when they spin round with their pegs fixed on the spot, are at rest and in motion at the same time (and he may say the same of anything which revolves in the same spot), his objection would not be admitted by us, because in such cases things are not at rest and in motion in the same parts of themselves; we should rather say that they have both an axis and a circumference, and that the axis stands still, for there is no deviation from the perpendicular; and that the circumference goes round. But if, while revolving, the axis inclines either to the right or left, forwards or backwards, then in no point of view can they be at rest. That is the correct mode of describing them, he replied. Then none of these objections will confuse us, or incline us to believe that the same thing at the same time, in the same part or in relation to the same thing, can act or be acted upon in contrary ways. Certainly not, according to my way of thinking. Yet, I said, that we may not be compelled to examine all such objections, and prove at length that they are untrue, let us assume their absurdity, and go forward on the understanding that hereafter, if this assumption turn out to be untrue, all the consequences which follow shall be withdrawn. Yes, he said, that will be the best way.

(24) Now in definitions, difference is assumed, which, in the definition, occupies the place of sign. The faculty of laughing, accordingly, being added to the definition of man, makes the whole - a rational, mortal, terrestrial, walking, laughing animal. For the things added by way of difference to the definition are the signs of the properties of things; but do not show the nature of the things themselves. Now they say that the difference is the assigning of what is peculiar; and as that which has the difference differs from all the rest, that which belongs to it alone, and is predicated conversely of the thing, must in definitions be assumed by the first genus as principal and fundamental.

(35) The following interesting quotation from a writer on the subject serves to bring out some of the main points concerned in the consideration of the activities of this particular principle: "Cyclicity is akin to Rhythm, and arise by reason of it. All events tend to move in cyclic trend—in constant circular movement. The Law of Cyclicity manifests in the universal tendency of things to swing in circles. Cyclicity is the outgrowth, or more complex form, of Rhythm. The primal manifestation of Rhythm is action to-and-fro in. a straight line or path—a movement backward and forward between two extremes or poles of action. This would be the invariable movement if the particular force manifested were the only manifestation of force or energy in that particular field of the Cosmos. But when the swinging pendulum (free to move in any direction) is subjected to the conflicting attractions and repulsions of other manifestations of force and energy, then there is manifested the universal tendency toward the circular trend—the tendency to convert the straight path of the swing into a circular path or cycle. The action and reaction, the attraction and repulsion, arising from the conflict between the force of the rhythmic swing in a straight line on the one hand, and the attractive and repellant forces from without, on the other hand, tend to swing the moving thing in a perfect circle around a central point, axis, or pivotal centre. And these conflicting forces are in operation through the Cosmos, and the manifestation of Cyclicity may be noticed on all planes. There is ever the evidence of the cyclic trend of things and events—the tendency to move in circles. The electrons in the atoms move in circles, just as do the planets around the sun, and just as does the sun move around some other centre in space.

(1) With respect to your inquiry, “ what the peculiarities are in each of the more excellent genera, by which they are separated from each other? ” if you understand by peculiarities the specific differences under the same genus, which are distinguished by opposite qualities, as the rational and irrational under animal; we by no means admit peculiarities of this kind, in things which neither have one common essence, nor an equal contradistinction, nor receive a composition from something common, which is indefinite, and defines the peculiarity. But if you apprehend the peculiarity to be, as in prior and secondary natures, differing in their whole essence and whole genus, a certain simple condition of being, definite in itself; in this case, your conception of peculiarities will be reasonable. For these peculiarities of things, which have an eternal subsistence, are simple, and entirely exempt. The inquiry, however, proceeds imperfectly. For it was necessary, in the first place, to inquire what the peculiarities are of the more excellent genera, according to essence; in the next place, what they are according to power; and thus afterwards, what they are according to energy.

(43) Timaeus: so that the whole of the living creature was moved, but in such a random way that its progress was disorderly and irrational, since it partook of all the six motions : for it progressed forwards and backwards, and again to right and to left, and upwards and downwards, wandering every way in all the six directions. For while the flood which foamed in and streamed out, as it supplied the food, was immense, still greater was the tumult produced

(8) Of this I'll give thee here on earth an instance, which the eye can see. Regard the animals down here - a man, for instance, swimming! The water moves, yet the resistance of his hands and feet give him stability, so that he is not borne along with it, nor sunk thereby. A: Thou hast, Thrice-greatest one, adduced a most clear instance. H: All motion, then, is caused in station and by station. The motion, therefore, of the cosmos (and of every other hylic to the cosmos, but by things interior [outward] to the exterior - such [things] as soul, or spirit, or some such other thing incorporeal. 'Tis not the body that doth move the living thing in it; nay, not even the whole [body of the universe a lesser] body e'en though there be no life in it.

(5) And, again, of the things contained under these ten Categories, some are Univocal, as ox and man, as far as each is an animal. For those are Univocal terms, to both of which belongs the common name, animal; and the same principle, that is definition, that is animate essence. And Heteronyms are those which relate to the same subject under different names, as ascent or descent; for the way is the same whether upwards or downwards. And the other species of Heteronyms, as horse and black, are those which have a different name and definition from each other, and do not possess the same subject. But they are to be called different, not Heteronyms. And Polyonyms are those which have the same definition, but a different name, as, hanger, sword, scimitar. And Paronyms are those which are named from something different, as "manly" from "manliness."

(7) Hence, too, the errant spheres, being moved contrarily to the inerrant one, are moved by one another by mutual contrariety, [and also] by the spable one through contrariety itself. And this can otherwise not be. The Bears up there , which neither set nor rise, think'st thou they rest or move? A: They move, Thrice-greatest one. H: And what their motion, my Asclepius? A: Motion that turns for ever round the same. H: But revolution - motion around same - is fixed by rest. For "round-the-same" doth stop "beyond-same". "Beyond-same" then, being stopped, if it be steadied in "round-same" - the contrary stands firm, being rendered ever stable by its contrariety.

(34) Timaeus: For movement He assigned unto it that which is proper to its body, namely, that one of the seven motions which specially belongs to reason and intelligence; wherefore He spun it round uniformly in the same spot and within itself and made it move revolving in a circle; and all the other six motions He took away and fashioned it free from their aberrations. And seeing that for this revolving motion it had no need of feet, He begat it legless and footless. Such, then, was the sum of the reasoning of the ever-existing God concerning the god

(4) For from its twofold source, everything has its great mobility, running, springing, driving and growing; For meekness in nature is a still rest, but the fierceness in every power makes all things moveable, running and generative.

(58) Timaeus: and motion in non-uniformity; and the cause of the non-uniform nature lies in inequality. Now we have explained the origin of inequality ; but we have not declared how it is that these bodies are not separated according to their several Kinds, and cease not from their motion and passage one through another. Wherefore, we shall once more expound the matter as follows. The revolution of the All, since it comprehends the Kinds, compresses them all, seeing that it is circular and tends naturally to come together to itself ; and thus it suffers no void place to be left.

(40) Timaeus: another the winged kind which traverses the air; thirdly, the class which inhabits the waters; and fourthly, that which goes on foot on dry land. The form of the divine class He wrought for the most part out of fire, that this kind might be as bright as possible to behold and as fair; and likening it to the All He made it truly spherical; and He placed it in the intelligence of the Supreme to follow therewith, distributing it round about over all the Heaven, to be unto it a veritable adornment cunningly traced over the whole. And each member of this class He endowed with two motions, whereof the one is uniform motion in the same spot, whereby it conceives always identical thoughts about the same objects,

(1) Now every single class of living thing, Asclepius, of whatsoever kind, or it be mortal or be rational, whether it be endowed with soul, or be without one, just as each has its class, so does each several [class] have images of its own class. And though each separate class of animal has in it every form of its own class, still in the selfsame [kind of] form the units differ from each other. And so although the class of men is of one kind, so that a man can be distinguished by his [general] look, still individual men within the sameness of their [common] form do differ from each other.

(89) Timaeus: Further, as concerns the motions, the best motion of a body is that caused by itself in itself; for this is most nearly akin to the motion of intelligence and the motion of the Universe. Motion due to the agency of another is less good; and the least good motion is that which is imparted to a body lying in a state of rest and which moves it piecemeal and by means of others. Wherefore the motion that is best for purgings and renovations of the body consists in gymnastic exercises; and second-best is the motion provided by swaying vehicles, such as boats or any conveyances that produce no fatigue; while the third kind of motion, although useful for one who is absolutely driven to it,

(9) Further, there is a movement of soul, circular indeed,--the entrance into itself from things without, and the unified convolution of its intellectual powers, bequeathing to it inerrancy, as it were, in a sort of circle, and turning and collecting itself, from the many things without, first to itself, then, as having become single, uniting with the uniquely unified powers, and thus conducting to the Beautiful and Good, which is above all things being, and One and the Same, and without beginning and without end. But a soul is moved spirally, in so far as it is illuminated, as to the divine kinds of knowledge, in a manner proper to itself, not intuitively and at once, but logically and discursively; and, as it were, by mingled and relative operations; but in a straight line, when, not entering into itself, and being moved by unique intuition (for this, as I said, is the circular), but advancing to things around itself, and from things without, it is, as it were, conducted from certain symbols, varied and multiplied, to the simple and unified contemplations.

(11) For of objects that are moved, some are moved by impulse and appearance, as animals; and some by transposition, as inanimate objects. And of things without life, plants, they say, are moved by transposition in order to growth, if we will concede to them that plants are without life. To stones, then, belongs a permanent state. Plants have a nature; and the irrational animals possess impulse and perception, and likewise the two characteristics already specified.

(47) In this ascending scale of animal life the student will perceive countless varieties and species, subspecies and variations among species. And in each there will be perceived some slight difference in the degree and quality of the intelligence manifested by the creature. Even among the individuals of the same species there is found a great variation in such manifestations. But throughout it all, there is perceived to be a certain general plane of consciousness which may be called "The Animal Plane" as distinguished from "The Mineral Plane" on the one hand, and "The Human Plane" on the other hand.

(13) These four Forms are in the Originality of Nature, and from thence the Mobility exists, as also the Life in the Seed, and in all the Creatures, has its Original from thence; and there is no Comprehensibility in the Originality, but such a Virtue or Power and Spirit. For it is a poisonous or venomous, hostile or enemicitious a Thing: And it must be so, or else there would be no Mobility, but all [would be as] nothing, and the Source of Wrath or Anger is the first Original of Nature.

(34) He has no impulse or driving, without or distinct from himself; his impulse and mobility stands in his body, which is of such a kind and manner as the whole God is; and his light and knowledge, as also his life, is generated in that manner as the whole divine being is generated.
