of our Organon, we have also the names of a great
Interpr. 11, 20, b, 26; Anal. pr.
i. 11, 24, b. 12 ; ii. 15, 17, 64, a,
37, 65, b, 16 ; Rliet. i. 1, 1355, a,
28, c. 2, 1356, b, 11, 1358, a, 29 ;
ii. 22, 1396, b, 4, c. 23, 1398, a,
28, 1399, a, 6, c. 25, 1402, a, 36,
c. 26, 1403, a, 32 ; iii. 18, 1419, a,
24). For the art of proof by
probabilities Aristotle uses the
term ' Dialectic ' (Top. init., Rliet.
init., etc.), and he refers to the
Topics in a similar way as irpayfiareia
ir. t^v SiaAe/cri/c^y (Anal,
pri. i. 30, 46, a, 30). It is probable,
therefore, that by ^e6o5i/c4
(Rliet. i. 2, 1356, b, 19) he meant
the Tojnos, which in the opening
words announce as their object,
peBoSov eipe'iv, etc., and in which
(i. 12, 105, a, 16 ; viii. 2 init.)
the relative passage is to be
found, rather than, as Heitz
(p. 81 sq., Fr. Hz. 117) suggests,
a lost work; cf. ROSE,
Ar. Zibr. Ord. 120 ; Vahlbn,
Wien. Altad, xxxviii. 99 ; Bonitz,
Ztschr. Oesterr. Gymn. 1866,
11, 774. It seems, also, that
in several MSS. the Topics were
headed with the title MedoSi/ccfc,
so that an idea arose that
they were distinct works. This
ideahasbeenattributedto Dionys.
(Up. I. ad Amm. 6, p. 729, on
Mhet. i. 2), but he speaks only of
avaKvriK^i KaX /x€0o8i/c^ irpayfiaTeia,
and does not specially include the
Topics in the latter. But D. 52
inserts McfloSi/ca in eight books,
and An. 49, the like title including
seven books, although
both know the Topics as well.
So Diog. (v. 29) distinguishes t a'.—The theory
of Spengel (Abli. d. Mimchn.
A/tad. vi. 497) that our text of
the Topics contains grave lacunce
does not seem to be proved by
the passages he quotes (Rliet. i.
2, 1356, b, 10; ii. 25, 1402, a,
34). As to the former, which
refers to the Topics only for the
