How then is multitude classified among relatives? It forms part of relatives in that multitude is an extension of number, while its contrary is a contraction. Likewise is it with continuous dimension; we conceive of it as prolonged. Quantity therefore has a double origin: progression of unity, and of the point. If either progression cease promptly, the first one produces "little," and the second, "small." If both be prolonged, they produce "much," and "large." What then is the limit that determines these things? The same question may be asked about the beautiful, and about warmth; for there is also "warmer"; only, the latter is a relative, while Warm, taken absolutely, is a quality. As there is a "reason" of the beautiful (a reason that would produce and determine the beautiful), likewise there must be a reason for the Great, a reason by participation in which an object becomes great, as the reason of the Beautiful makes beautiful. Such are the things for which quantity admits contraries. THERE IS NO CONTRARY FOR PLACE. For space, there is no contrary, because strictly space does not belong to the genus of quantity. Even if space were part of quantity, "high" would not be the contrary of anything unless the universe contained also "low." The terms high and low, applied to parts, signify only higher and lower than something else. It is so also with right and left, which are relatives. CLASSIFICATION OF SYLLABLES AND SPEECH. Syllables and speech are quantitatives; they might be subjects in respect to quantity, but only so by accident. Indeed, the voice, by itself, is a movement,[386] it must therefore be reduced to movement and action. DISCRETE QUANTITY QUITE DISTINCT FROM CONTINUOUS QUANTITY. 13. We have already explained that discrete quantity is clearly distinguished from continuous quantity, both by its own definition, and the general definition (for quantity).[387] We may add that numbers are distinguished from each other by being even and odd. If besides there be other differences amidst the even and odd numbers, these differences will have to be referred to the objects in which are the numbers, or to the numbers composed of unities, and not any more to those which exist in sense-beings. If reason separate sense-things from the numbers they contain, nothing hinders us then from attributing to these numbers the same differences (as to the numbers composed of unities).[388] ELEMENTS OF CONTINUOUS QUANTITY.
