Opposite and contrary, other in species

Paragraph 1	The term 'opposite' is applied to contradictories, and to contraries, and to relative terms, and to privation and possession, and to the extremes from which and into which generation and dissolution take place;
Paragraph 2	The term 'contrary' is applied:
Paragraph 3	(1) to those attributes differing in genus which cannot belong at the same time to the same subject,
Paragraph 4	(2) to the most different of the things in the same genus,
Paragraph 5	(3) to the most different of the attributes in the same recipient subject,
Paragraph 6	(4) to the most different of the things that fall under the same faculty,
Paragraph 7	(5) to the things whose difference is greatest either absolutely or in genus or in species.
Paragraph 8	The other things that are called contrary are so called, some because they possess contraries of the above kind, some because they are receptive of such, some because they are productive of or susceptible to such, or are producing or suffering them, or are losses or acquisitions, or possessions or privations, of such.
Paragraph 9	The term 'other in species' is applied to things which being of the same genus are not subordinate the one to the other, or which being in the same genus have a difference, or which have a contrariety in their substance;
