On the stylistic argument as applied to Platonic controversies Janell's _Quaestiones Platonicae_ (1901) is important. On the whole question of genuineness and dates of the dialogues, H. Raeder, _Platons philosophische Entwickelung_ (1905), gives an excellent conspectus of the views held and the grounds alleged. See also PLATO. [22] E.g. that of essence and accident. Republic, 454. [23] E.g. the discussion of correlation, ib. 437 sqq. [24] _Politicus_, 285d. [25] _Sophistes_, 261c sqq. [26] E.g. in _Nic. Eth._ i. 6. [27] _Philebus_, 16d. [28] Principal edition still that of Waitz, with Latin commentary, (2 vols., 1844-1846). Among the innumerable writers who have thrown light upon Aristotle's logical doctrine, St Hilaire, Trendelenburg, Ueberweg, Hamilton, Mansel, G. Grote may be named. There are, however, others of equal distinction. Reference to Prantl, op. cit., is indispensable. Zeller, _Die philosophie der Griechen_, ii. 2, "Aristoteles" (3rd ed., 1879), pp. 185-257 (there is an Eng. trans.), and Maier, _Die Syllogistik des Aristoteles_ (2 vols., 1896, 1900) (some 900 pp.), are also of first-rate importance. [29] _Sophist. Elench._ 184, espec. b 1-3, but see Maier, _loc. cit._ i. 1. [30] References such as 18b 12 are the result of subsequent editing and prove nothing. See, however, ARISTOTLE. [31] Adrastus is said to have called them [Greek: pro tôn topikôn]. [32] _Metaphys._ E. 1. [33] _De Part. Animal._ A. 1, 639a 1 sqq.; cf. _Metaphys._ 1005b 2 sqq. [34] _De Interpretatione_ 16a sqq. [35] _De Interpretatione_ 16a 24-25. [36] _Ib._ 18a 28 sqq. [37] _Ib._ 19a 28-29. [38] As shown e.g. by the way in which the relativity of sense and the object of sense is conceived, 7b 35-37. [39] _Topics_ 101a 27 and 36-b 4. [40] _Topics_ 100. [41] _Politics_ 1282a 1 sqq. [42] 103b 21. [43] _Topics_ 160a 37-b 5. [44] This is the explanation of the formal definition of induction, _Prior Analytics_, ii. 23, 68b 15 sqq. [45] 25b 36. [46] _Prior Analytics_, i. 1. 24a 18-20, [Greek: Syllogismos de esti logos en ô tethentôn tinôn eteron ti tôn keimenôn ex anankês snmbainei tô tauta einai]. The equivalent previously in _Topics_ 100a 25 sqq. [47] _Prior Analytics_, ii. 21; _Posterior Analytics_, i. 1. [48] 67a 33-37, [Greek: mê syntheôrôn to kath' ekateron]. [49] 67a 39-63. [50] 79a 4-5. [51] 24b 10-11. [52] _Posterior Analytics_, i. 4 [Greek: kath auto] means (1) contained in the definition of the subject; (2) having the subject contained in its definition, as being an alternative determination of the subject, crooked, e.g. is _per se_ of line; (3) self-subsistent; (4) connected with the subject as consequent to ground. Its needs stricter determination therefore. [53] 73b 26 sqq., 74a 37 sqq. [54] 90b 16.
