Aristotle - index for METAPHYSICA Book 10 Part 4


Paragraph 1 Since things which differ may differ from one another more or less, there is also a greatest difference, and this I call contrariety.
Paragraph 2 But surely that which is greatest in each class is complete.
Paragraph 3 This being so, it is clear that one thing have more than one contrary (for neither can there be anything more extreme than the extreme, nor can there be more than two extremes for the one interval), and, to put the matter generally, this is clear if contrariety is a difference, and if difference, and therefore also the complete difference, must be between two things.
Paragraph 4 And the other commonly accepted definitions of contraries are also necessarily true.
Paragraph 5 For not only is (1) the complete difference the greatest difference (for we can get no difference beyond it of things differing either in genus or in species;
Paragraph 6 but also (2) the things in the same genus which differ most are contrary (for the complete difference is the greatest difference between species of the same genus);
Paragraph 7 and (3) the things in the same receptive material which differ most are contrary (for the matter is the same for contraries);
Paragraph 8 and (4) of the things which fall under the same faculty the most different are contrary (for one science deals with one class of things, and in these the complete difference is the greatest).
Paragraph 9 The primary contrariety is that between positive state and privation - not every privation, however (for 'privation' has several meanings), but that which is complete.
Paragraph 10 And this is obvious also by induction.
