justly with courageously. So also with opposites, for if these be the same, the opposites to these also are the same, according to any of the modes of opposition stated, since it makes no difference whether we take an opposite to this or that, as they are the same. Again, from efficients and corruptives, also from generations, corruptions, and in short, from things which subsist similarly with reference to either, for whatever are simply the same, the generations and corruptions also of these are the same, and besides, the efficients and corruptives.
Examine also, whether of those things of which one is especially said to be a certain thing, another also is especially predicated according to the same; as Xenocrates shows that a happy and a worthy life are the same, because a worthy and a happy, are the most eligible of all lives, for the most eligible, and the greatest, are one thing. Likewise, in other things of the same kind; yet it is necessary that each of those which are said to be the greatest, or the most eligible, should be one in number, otherwise it will not be demonstrated that it is the same, since it is not necessary, if the Peloponnesians and the Lacedæmonians are the bravest of the Greeks, that the Peloponnesians should be the same with the Lacedæmonians, as a Peloponnesian and a Lacedaemonian are not one in number. Still it is requisite that one should be contained under the other, as Lacedæmonians under Peloponnesians, otherwise it will happen that they are better than each other, if the one be not comprehended under the other, for it is necessary that the Peloponnesians should be better than the Lacedæmonians, if the one be not contained under the other, for they are better than all the rest (of the Greeks). So also it is necessary that the Lacedæmonians should be better than the Peloponnesians, for these also are better than all the rest, so that they are better than each other. It is clear then, that what is said to be best, and greatest, ought to be one in number, if we would show that it is the same, for which reason
