Book 10
4
To all things, however, which are divisible the term many is applicable: in one sense, if there is a plurality which involves excess either absolutely or relatively (and similarly few is a plurality involving defect); and in another in the sense of number, in which case it is opposed to one only. For we say one or many just as if we were to say one and ones, or white thing and white things, or were to compare the things measured with the measure.
5
Multiples, too, are spoken of in this way; for every number is many, because it consists of ones, and because every number is measurable by one; and also as being the opposite of one, and not of few. In this sense even two is many; but as a plurality involving excess either relatively or absolutely it is not many, but the first plurality. Two is, however, absolutely few; because it is the first plurality involving defect
