But if it pleases our adversaries to say that the significance of the term is not operation, but nature, we shall fall back upon our original argument, that custom applies the name of a nature to denote multitude erroneously: since according to true reasoning neither diminution nor increase attaches to any nature, when it is contemplated in a larger or smaller number. For it is only those things which are contemplated in their individual circumscription which are enumerated by way of addition. Now this circumscription is noted by bodily appearance, and size, and place, and difference figure and colour, and that which is contemplated apart from these conditions is free from the circumscription which is formed by such categories. That which is not thus circumscribed is not enumerated, and that which is not enumerated cannot be contemplated in multitude. For we say that gold, even though it be cut into many figures, is one, and is so spoken of, but we speak of many coins or many staters, without finding any multiplication of the nature of gold by the number of staters; and for this reason we speak of gold, when it is contemplated in greater bulk, either in plate or in coin, as “much,” but we do not speak of it as “many golds” on account of the multitude of the material,—except when one says there are “many gold pieces” (Darics, for instance, or staters), in which case it is not the material, but the pieces of money to which the significance of number applies: indeed, properly, we should not call them “gold” but “golden.”
