All men by nature desire to know. An indication of this is the delight we take in our senses.Metaphysics, Book I.1 (980a), trans. W. D. Ross

36-37. ‘ And so they identify the odd with the One (a principle, not a number); for if oddness had depended on the first odd numéer, how would 5 (which according to the theory has not the ideal 3 in it) be odd?’ To say that the number 3 is the principle of oddness would imply deriving 5 from the union of 2 and 3, whereas according to the Platonic view itis otherwise derived.

The force of 80 seems to be this: The Platonists derived all derivative entities either from the first principles or from the numbers up to 10. Now oddness could not be derived from a number such as 3, because this would not explain the oddness of any other number (the numbers being supposed independent of each other) ; sherefore it had to be derived from one of the principles, and of the two the One rather than the indefinite dyad was indicated for the purpose.

SexdSos, ‘ Further, magnitudes and the like extend, they say, only up to a certain point, e.g. there is the first or indivi- sible line, then the two, &c.; these entities also extend only up to ro.’ Aristotle is giving a further ground for his statement that the Pla- tonists treat 10 as the perfect or complete number (I. 31). They recognize first the primary or indivisible line (their substitute for the ‘point’ of geometrical theory, A. 992% 22). mpdérn ypappi) dropos is difficult, and it seems best to read 4} rpérn ypayyn, 4 dropos. (Alterna- tively we might omit % after otov as Schwegler proposes, and translate ‘first comes the indivisible line’; but 7 is more likely to have been omitted after zpary than to have been inserted after ofov.) I know of no exact parallel to zpwry ypaypy in this sense, but in A. 9924 21 the indivisible line is called dpy% ypappys, and 4 te dpxi mpGrov Kal 70 mpa@tov dpyyn, Top, 121? 9.

Certain Platonists (A. 992°21, De An. 404» 16-24 suggest that Plato himself was among them, while a comparison with N. 1090 20- 32 suggests that Xenocrates also is referred to) connected the point or indivisible line with the number 1, the line with 2, the plane with 3, the solid with 4 (N. rogob22, Z. 1036514, H. 1043%33); and I+24+3+4= Io.

b 4-13. The discussion whether the One or number is prior may be compared with the discussion in Z. 10, 11, where the same illustration (the right and acute angles) is used (1034> 28, 10356, 1036% 14). The present passage seems to be written without any reference to the previous one.

15-16. ddXG tpdtrov Gov kth, An opposition of ‘indivisible in Aéyos’ and ‘indivisible in time’ would be quite unparalleled in Aristotle, and no reasonable meaning can be attached to it. Alexander explains that the universal is indivisible in Adyos because ‘ footed two-footed animal’ is not divisible into other Adyou and eidy as ‘animal’ is into ‘man’ and ‘horse ’—which is evidently nonsense ; and that the particular is indivisible in time because my form is not prior in time to me— which, besides interpreting 76 émi pépovs in a sense which we have seen reason to doubt, is a very unnatural interpretation of ‘indivisible in time’. Nor does any better interpretation of this last phrase seem possible. We are driven, then, to suppose that rpomov dAXov KTAi does not qualify ‘indivisible’. Ifwith Bekker we read a full stop before dAAd, we may take tpdrov addAov as qualifying dpyy. ‘The One is

said to be dpxy because it is indivisible. But the universal as well as the element is indivisible. Yes, but their consequent primariness is of different kinds.’ We thus get the ordinary opposition of zpdérepov Aoyw and xpovw, for which cf. ll. 12, 13, Z. 1028%32, 1038 27, @. 1049 11, Phys. 265% 22.

18. Kat ckatépa, pia may mean (1), as Alexander says, ‘ and each of these is one and the same with itself’. I.e. these words may simply emphasize the fact that one single thing may be in one sense prior, in another posterior, to another single thing. But it seems more likely (2) that these words fit into the argument as follows: In which sense is the One dpxyn? The right angle is prior to the acute angle, and in another sense the acute angle is prior to the right angle, and each of these is one (s¢.the acute angle is one as an element is one, and the right angle is one as a whole—here confused with a universal—is one). |The Platonists accordingly (84) make the One primary in both senses, in time and in Aéyos. But this is impossible ; for ‘One’ is here used ambiguously— it is what is one, as a form or essence (= universal) is one, that is primary xara Adyov, but it is what is one as a part, or as matter, that is primary kata xpovov.

or element in the definition predicable of each number, as well as a material part of it. For this line of thought about 76 év, which led the Platonists to treat it as the very essence of real things, cf. B. 996 4, 998 17, 10017 4, 20, I. 10539, 20, K. 1059 27, 1060? 3.

Thus the two clauses have not any such connexion as ydp indicates, and can hardly be right as they stand. Alexander feels no difficulty, but gives an impossible interpretation; and Bz’.s interpretation, which takes aerov as if it could mean dpyixdy, does nothing to meet the difficulty. The proposed emendations of dOerov (ddvaiperov Schwegler, dovvOerov Bywater) would give a satisfactory sense if it were not for pdvov, but in the presence of povov are unsatisfactory. Two suggestions may be made. (tr) It is just possible that a@eroy may be used in a new sense. Each unit has, on the Platonic view, a setting or Oéc1s in some parti- cular number ; all that distinguishes the One which is the formal prin- ciple of number is that it has no such particular setting, that it is aerov. It would not be unlike Aristotle to use dOeros thus in a different sense from that which it bore in l. 27, but the suggested use of d@eros is apparently without parallel. (2) We might suppose povaducoy to have been corrupted into pdvoy ddiov, and this to have been altered through a reminiscence of ]. 27 into povoy aberov.

1085* 1-2. The argument is not, as Bz. says, the same as that in 1081 25-35. It is simply this: If one thing added to another always makes a two, the two itself and the three itself make a two, and a two of whose generation the Platonists can give no account. They cannot derive it from the One and the indefinite dyad, since what these originate is the two itself, the three itself, and so on.

6. Bz. reads r@ ebe&fs and claims the authority of Alexander. But it is not clear what Alexander read, so that it seems better to retain the manuscript reading trav édeéjs, which gives a good sense. Aristotle does not here state the objections which follow if (1) the units, or one of the units, in two, or (2) two itself, are to succeed the number one directly. The objection to (1) is that then there is a two (composed of the number one + one of the units in two) before there is the number two itself (cf. 10818 32). The objection to (2) is that the first unit in two, being prior to the second unit, should be prior to the two composed of them (10818 25~27),

(1) That it is the various kinds of the great and the small (108529, A. 992%11, N. 1090537). Some, if we may believe Aristotle, did not distinguish the great and the small which is the material principle of number from that which is the material principle of spatial magnitudes (B. roo1» 19). Al. 228. 10, Asc. 207. 37, Syr. 48. 20 think Plato himself is here referred to, and this may well be so. Others divided the great and small into the many and few, which is the épy7 of number, and the long and short, the broad and narrow, the deep and shallow, which are the dpxaé of spatial magnitudes (N. 1089? 11).
