each, seems predicated similarly, and of the same number, as in "a gift," and "giving," for a "gift," is said to be "of" some one, or "to" some one, and "giving" also, "of" a certain one, and "to" a certain one; still "giving" is the genus of "gift," for "a gift," is "a giving" not to be returned. With some, predication with reference to an equal number, does not occur; for the double is the double of something, but the excessive, and the greater, (are predicated) of, and with reference to, a certain thing, for every thing excessive, and that which is greater, exceeds in something, and is the excess of a certain thing. Wherefore, what are mentioned, are not the genera of the double, since they are not predicated with reference to an equal number in species, or it is not universally true that species and genus are predicated with reference to an equal number of things.
Examine, likewise, whether the opposite is the genus of the opposite, as if the multiple is the genus of the double, the sub-multiple is so, of the half, for the opposite must necessarily be the genus of the opposite. If, then, any one asserts science to be sense, it will be requisite that the object of science should be sensible, which, however, is not the case, for not every object of science is sensible, as some things intelligible are objects of science. Wherefore, the sensible is not the genus of the object of science, but if it be not, neither is sense, the genus of science.
Nevertheless, since of those which are enunciated with reference to any thing, some are necessarily in, or about, those, to which they happen to be referred, as disposition, habit, and symmetry, (for these can possibly be in nothing else, than in those things to which they are referred;) but others are not necessarily in those, to which they are sometimes referred, yet may be in them, (as if the soul is an object of science, since nothing prevents the soul having science of itself, yet it is not necessary, since this very science may possibly be in something
