6 Next, look from the point of view of the respective opposites, and first (a) from that of the contraries, and see, for destructive purposes, if the contrary of the term rendered fails to be a property of the contrary subject. For then neither will the contrary of the first be a property of the contrary of the second. Thus (e.g.) inasmuch as injustice is contrary to justice, and the lowest evil to the highest good, but ‘to be the highest good’ is not a property of ‘justice’, therefore ‘to be the lowest evil’ could not be a property of ‘injustice’. For constructive purposes, on the other hand, see if the contrary is the property of the contrary: for then also the contrary of the first will be the property of the contrary of the second. Thus (e.g.) inasmuch as evil is contrary to good, and objectionable to desirable, and ‘desirable’ is a property of ‘good’, ‘objectionable’ would be a property of ‘evil’. Secondly (h) look from the point of view of relative opposites and see, for destructive purposes, if the correlative of the term rendered fails to be a property of the correlative of the subject: for then neither will the correlative of the first be a property of the correlative of the second. Thus (e.g.) inasmuch as ‘double’ is relative to ‘half’, and ‘in excess’ to ‘exceeded’, while ‘in excess’ is not a property of ‘double’, exceeded’ could not be a property of ‘half’. For constructive purposes, on the other hand, see if the correlative of the alleged property is a property of the subject’s correlative: for then also the correlative of the first will be a property of the correlative of the second: e.g. inasmuch as ‘double’ is relative to ‘half’, and the proportion 1:2 is relative to the proportion 2:1, while it is a property of ‘double’ to be ‘in the proportion of 2 to 1’, it would be a property of ‘half’ to be ‘in the proportion of 1 to 2’. Thirdly (c) for destructive purposes, see if an attribute described in terms of a state (X) fails to be a property of the given state (Y): for then neither will the attribute described in terms of the privation (of X) be a property of the privation (of Y). Also if, on the other hand, an attribute described in terms of the privation (of X) be not a property of the given privation (of Y), neither will the attribute described in terms of the state (X) be a property of the state (Y). Thus, for example, inasmuch as it is not predicated as a property of ‘deafness’ to be a ‘lack of sensation’, neither could it be a property of ‘hearing’ to be a ‘sensation’. For constructive purposes, on the other hand, see if an attribute described in terms of a state (X) is a property of the given state (Y): for then also the attribute that is described in terms of the privation (of X) will be a property of the privation (of Y). Also, if an attribute described in terms of a privation (of X) be a property of the privation (of Y), then also the attribute that is described in terms of the state (X) will be a property of the state (Y). Thus (e.g.) inasmuch as ‘to see’ is a property of ‘sight’, inasmuch as 282
