<* Other groups will get broken up under several lines of 

 division, as Aristotle goes on to say, and he repeats this at 

 643 b 14, where he adds that " contrary " groups will get 

 lumped together under a single line (and " contrariety is 

 maximum ' difference,' " see Met. 1055 a 5 ff., cf. 1018 a 30). 



" Aristotle holds that one is not enough ; see 643 b 9 ff. 

 and 29 ff.
