   consecutive series of motions. The only continuous motion, then, is
   that which is caused by the unmoved movent: and this motion is
   continuous because the movent remains always invariable, so that its
   relation to that which it moves remains also invariable and
   continuous.
   Now that these points are settled, it is clear that the first
   unmoved movent cannot have any magnitude. For if it has magnitude,
   this must be either a finite or an infinite magnitude. Now we have
   already'proved in our course on Physics that there cannot be an
   infinite magnitude: and we have now proved that it is impossible for a
   finite magnitude to have an infinite force, and also that it is
   impossible for a thing to be moved by a finite magnitude during an
   infinite time. But the first movent causes a motion that is eternal
   and does cause it during an infinite time. It is clear, therefore,
   that the first movent is indivisible and is without parts and
   without magnitude.

   POETICS|1
   I
   I PROPOSE to treat of Poetry in itself and of its various kinds,
   noting the essential quality of each, to inquire into the structure of
   the plot as requisite to a good poem; into the number and nature of
   the parts of which a poem is composed; and similarly into whatever
   else falls within the same inquiry. Following, then, the order of
   nature, let us begin with the principles which come first.
   Epic poetry and Tragedy, Comedy also and Dithyrambic poetry, and the
   music of the flute and of the lyre in most of their forms, are all
   in their general conception modes of imitation. They differ,
   however, from one another in three respects- the medium, the
   objects, the manner or mode of imitation, being in each case distinct.
   For as there are persons who, by conscious art or mere habit,
   imitate and represent various objects through the medium of color
   and form, or again by the voice; so in the arts above mentioned, taken
   as a whole, the imitation is produced by rhythm, language, or
   'harmony,' either singly or combined.
   Thus in the music of the flute and of the lyre, 'harmony' and rhythm
   alone are employed; also in other arts, such as that of the shepherd's
   pipe, which are essentially similar to these. In dancing, rhythm alone
   is used without 'harmony'; for even dancing imitates character,
   emotion, and action, by rhythmical movement.
   There is another art which imitates by means of language alone,
   and that either in prose or verse- which verse, again, may either
   combine different meters or consist of but one kind- but this has
   hitherto been without a name. For there is no common term we could
   apply to the mimes of Sophron and Xenarchus and the Socratic dialogues
   on the one hand; and, on the other, to poetic imitations in iambic,
   elegiac, or any similar meter. People do, indeed, add the word 'maker'
   or 'poet' to the name of the meter, and speak of elegiac poets, or
   epic (that is, hexameter) poets, as if it were not the imitation
   that makes the poet, but the verse that entitles them all to the name.
   Even when a treatise on medicine or natural science is brought out
   in verse, the name of poet is by custom given to the author; and yet
   Homer and Empedocles have nothing in common but the meter, so that
   it would be right to call the one poet, the other physicist rather
   than poet. On the same principle, even if a writer in his poetic
   imitation were to combine all meters, as Chaeremon did in his Centaur,
   which is a medley composed of meters of all kinds, we should bring him
   too under the general term poet.
   So much then for these distinctions.
   There are, again, some arts which employ all the means above
   mentioned- namely, rhythm, tune, and meter. Such are Dithyrambic and
   Nomic poetry, and also Tragedy and Comedy; but between them originally
   the difference is, that in the first two cases these means are all
   employed in combination, in the latter, now one means is employed, now
   another.
   Such, then, are the differences of the arts with respect to the
   medium of imitation
   POETICS|2
   II
   Since the objects of imitation are men in action, and these men must
   be either of a higher or a lower type (for moral character mainly
   answers to these divisions, goodness and badness being the
   distinguishing marks of moral differences), it follows that we must
   represent men either as better than in real life, or as worse, or as
   they are. It is the same in painting. Polygnotus depicted men as
   nobler than they are, Pauson as less noble, Dionysius drew them true
   to life.
   Now it is evident that each of the modes of imitation above
   mentioned will exhibit these differences, and become a distinct kind
   in imitating objects that are thus distinct. Such diversities may be
   found even in dancing, flute-playing, and lyre-playing. So again in
   language, whether prose or verse unaccompanied by music. Homer, for
   example, makes men better than they are; Cleophon as they are; Hegemon
   the Thasian, the inventor of parodies, and Nicochares, the author of
   the Deiliad, worse than they are. The same thing holds good of
   Dithyrambs and Nomes; here too one may portray different types, as
   Timotheus and Philoxenus differed in representing their Cyclopes.
   The same distinction marks off Tragedy from Comedy; for Comedy aims at
   representing men as worse, Tragedy as better than in actual life.
   POETICS|3
   III
   There is still a third difference- the manner in which each of these
   objects may be imitated. For the medium being the same, and the
   objects the same, the poet may imitate by narration- in which case
   he can either take another personality as Homer does, or speak in
   his own person, unchanged- or he may present all his characters as
   living and moving before us.
   These, then, as we said at the beginning, are the three
   differences which distinguish artistic imitation- the medium, the
   objects, and the manner. So that from one point of view, Sophocles
   is an imitator of the same kind as Homer- for both imitate higher
   types of character; from another point of view, of the same kind as
   Aristophanes- for both imitate persons acting and doing. Hence, some
   say, the name of 'drama' is given to such poems, as representing
   action. For the same reason the Dorians claim the invention both of
   Tragedy and Comedy. The claim to Comedy is put forward by the
   Megarians- not only by those of Greece proper, who allege that it
   originated under their democracy, but also by the Megarians of Sicily,
   for the poet Epicharmus, who is much earlier than Chionides and
   Magnes, belonged to that country. Tragedy too is claimed by certain
   Dorians of the Peloponnese. In each case they appeal to the evidence
   of language. The outlying villages, they say, are by them called
   komai, by the Athenians demoi: and they assume that comedians werer />
   so named not from komazein, 'to revel,' but because they wandered from
   village to village (kata komas), being excluded contemptuously from
   the city. They add also that the Dorian word for 'doing' is dran,
   and the Athenian, prattein.
   This may suffice as to the number and nature of the various modes of
   imitation.
   POETICS|4
   IV
   Poetry in general seems to have sprung from two causes, each of them
   lying deep in our nature. First, the instinct of imitation is
   implanted in man from childhood, one difference between him and
   other animals being that he is the most imitative of living creatures,
   and through imitation learns his earliest lessons; and no less
   universal is the pleasure felt in things imitated. We have evidence of
   this in the facts of experience. Objects which in themselves we view
   with pain, we delight to contemplate when reproduced with minute
   fidelity: such as the forms of the most ignoble animals and of dead
   bodies. The cause of this again is, that to learn gives the
   liveliest pleasure, not only to philosophers but to men in general;
   whose capacity, however, of learning is more limited. Thus the
   reason why men enjoy seeing a likeness is, that in contemplating it
   they find themselves learning or inferring, and saying perhaps, 'Ah,
   that is he.' For if you happen not to have seen the original, the
   pleasure will be due not to the imitation as such, but to the
   execution, the coloring, or some such other cause.
   Imitation, then, is one instinct of our nature. Next, there is the
   instinct for 'harmony' and rhythm, meters being manifestly sections of
   rhythm. Persons, therefore, starting with this natural gift
   developed by degrees their special aptitudes, till their rude
   improvisations gave birth to Poetry.
   Poetry now diverged in two directions, according to the individual
   character of the writers. The graver spirits imitated noble actions,
   and the actions of good men. The more trivial sort imitated the
   actions of meaner persons, at first composing satires, as the former
   did hymns to the gods and the praises of famous men. A poem of the
   satirical kind cannot indeed be put down to any author earlier than
   Homer; though many such writers probably there were. But from Homer
   onward, instances can be cited- his own Margites, for example, and
   other similar compositions. The appropriate meter was also here
   introduced; hence the measure is still called the iambic or lampooning
   measure, being that in which people lampooned one another. Thus the
   older poets were distinguished as writers of heroic or of lampooning
   verse.
   As, in the serious style, Homer is pre-eminent among poets, for he
   alone combined dramatic form with excellence of imitation so he too
   first laid down the main lines of comedy, by dramatizing the ludicrous
   instead of writing personal satire. His Margites bears the same
   relation to comedy that the Iliad and Odyssey do to tragedy. But
   when Tragedy and Comedy came to light, the two classes of poets
   still followed their natural bent: the lampooners became writers of
   Comedy, and the Epic poets were succeeded by Tragedians, since the
   drama was a larger and higher form of art.
   Whether Tragedy has as yet perfected its proper types or not; and
   whether it is to be judged in itself, or in relation also to the
   audience- this raises another question. Be that as it may, Tragedy- as
   also Comedy- was at first mere improvisation. The one originated
   with the authors of the Dithyramb, the other with those of the phallic
   songs, which are still in use in many of our cities. Tragedy
   advanced by slow degrees; each new element that showed itself was in
   turn developed. Having passed through many changes, it found its
   natural form, and there it stopped.
   Aeschylus first introduced a second actor; he diminished the
   importance of the Chorus, and assigned the leading part to the
   dialogue. Sophocles raised the number of actors to three, and added
   scene-painting. Moreover, it was not till late that the short plot was
   discarded for one of greater compass, and the grotesque diction of the
   earlier satyric form for the stately manner of Tragedy. The iambic
   measure then replaced the trochaic tetrameter, which was originally
   employed when the poetry was of the satyric order, and had greater
   with dancing. Once dialogue had come in, Nature herself discovered the
   appropriate measure. For the iambic is, of all measures, the most
   colloquial we see it in the fact that conversational speech runs
   into iambic lines more frequently than into any other kind of verse;
   rarely into hexameters, and only when we drop the colloquial
   intonation. The additions to the number of 'episodes' or acts, and the
   other accessories of which tradition tells, must be taken as already
   described; for to discuss them in detail would, doubtless, be a
   large undertaking.
   POETICS|5
   V
   Comedy is, as we have said, an imitation of characters of a lower
   type- not, however, in the full sense of the word bad, the ludicrous
   being merely a subdivision of the ugly. It consists in some defect
   or ugliness which is not painful or destructive. To take an obvious
   example, the comic mask is ugly and distorted, but does not imply
   pain.
   The successive changes through which Tragedy passed, and the authors
   of these changes, are well known, whereas Comedy has had no history,
   because it was not at first treated seriously. It was late before
   the Archon granted a comic chorus to a poet; the performers were
   till then voluntary. Comedy had already taken definite shape when
   comic poets, distinctively so called, are heard of. Who furnished it
   with masks, or prologues, or increased the number of actors- these and
   other similar details remain unknown. As for the plot, it came
   originally from Sicily; but of Athenian writers Crates was the first
   who abandoning the 'iambic' or lampooning form, generalized his themes
   and plots.
   Epic poetry agrees with Tragedy in so far as it is an imitation in
   verse of characters of a higher type. They differ in that Epic
   poetry admits but one kind of meter and is narrative in form. They
   differ, again, in their length: for Tragedy endeavors, as far as
   possible, to confine itself to a single revolution of the sun, or
   but slightly to exceed this limit, whereas the Epic action has no
   limits of time. This, then, is a second point of difference; though at
   first the same freedom was admitted in Tragedy as in Epic poetry.
   Of their constituent parts some are common to both, some peculiar to
   Tragedy: whoever, therefore knows what is good or bad Tragedy, knows
   also about Epic poetry. All the elements of an Epic poem are found
   in Tragedy, but the elements of a Tragedy are not all found in the
   Epic poem.
   POETICS|6
   VI
   Of the poetry which imitates in hexameter verse, and of Comedy, we
   will speak hereafter. Let us now discuss Tragedy, resuming its
   formal definition, as resulti
ng from what has been already said.
   Tragedy, then, is an imitation of an action that is serious,
   complete, and of a certain magnitude; in language embellished with
   each kind of artistic ornament, the several kinds being found in
   separate parts of the play; in the form of action, not of narrative;
   through pity and fear effecting the proper purgation of these
   emotions. By 'language embellished,' I mean language into which
   rhythm, 'harmony' and song enter. By 'the several kinds in separate
   parts,' I mean, that some parts are rendered through the medium of
   verse alone, others again with the aid of song.
   Now as tragic imitation implies persons acting, it necessarily
   follows in the first place, that Spectacular equipment will be a
   part of Tragedy. Next, Song and Diction, for these are the media of
   imitation. By 'Diction' I mean the mere metrical arrangement of the
   words: as for 'Song,' it is a term whose sense every one understands.
   Again, Tragedy is the imitation of an action; and an action
   implies personal agents, who necessarily possess certain distinctive
   qualities both of character and thought; for it is by these that we
   qualify actions themselves, and these- thought and character- are
   the two natural causes from which actions spring, and on actions again
   all success or failure depends. Hence, the Plot is the imitation of
   the action- for by plot I here mean the arrangement of the
   incidents. By Character I mean that in virtue of which we ascribe
   certain qualities to the agents. Thought is required wherever a
   statement is proved, or, it may be, a general truth enunciated.
   Every Tragedy, therefore, must have six parts, which parts determine
   its quality- namely, Plot, Character, Diction, Thought, Spectacle,
   Song. Two of the parts constitute the medium of imitation, one the
   manner, and three the objects of imitation. And these complete the
