First, let us consider speech. It can be measured.[254] In this respect, speech is a quantity, but not in so far as it is speech, whose nature is to be significant, as the noun, or the verb.[255] The vocal air is the matter of the word, as it also is of the noun and the verb, all which constitute the language. The word is principally an impulse launched on the air, but it is not a simple impulse; because it is articulated it somehow fashions the air; consequently it is a deed, but a significant one. It might be reasonably said that this movement and impulse constitute a deed, and that the movement which follows is a modification, or rather that the first movement is the deed, and the second movement is the modification of another, or rather that the deed refers to the subject, and the modification is in the subject. If the word consisted not in the impulse, but in the air, there would result from the significant characteristic of the expressive impulse two distinct entities, and no longer a single category. NEITHER IS TIME A QUANTITY. Let us pass to time.[256] If it exist in what measures, that which measures must be examined; it is doubtless the soul, or the present instant. If it exist in what is measured, it is a quantity so far as it has a quantity; as, for instance, it may be a year. But, so far as it is time, it has another nature; for what has such a quantity, without (essentially) being a quantity, is not any the less such a quantity. QUANTITY AS EQUAL AND UNEQUAL DOES NOT REFER TO THE OBJECTS. As to (Aristotle's) assertion that the property of quantity is to be both equal and unequal,[257] this property belongs to quantity itself, and not to the objects which participate in quantity, unless it be by accident, so far as one does not consider these objects in themselves. A three foot object, for instance, is a quantity so far as it is taken in its totality; but it does not form a kind with quantity itself; only, along with it, it is traced back to a kind of unity, a common category.
