The composition of the bodies being varied, they may also be classified according to the specific forms of the animals. Such, for instance, would be the specific form of a man united to a body; for this form is a quality of body, and it is reasonable to analyze it according to the qualities. If it should be objected that we have said above that some bodies are simple, while others are composite, thus contrasting the simple and the composite, we shall answer that, without regarding their composition, we have also said that they are either brute or organized. The classification of bodies should not be founded on the contrast between the simple and the composite, but, as we first did, we may classify the simple bodies in the first rank. Then, by considering their blendings, one may start from another principle to determine the differences offered by the composites under the respect of their figure or their location; thus, for instance, bodies might be classified in celestial and terrestrial. This may close our consideration of sense-being, or generation. DEFINITION OF QUANTITY. 11. Let us now pass to quantity and quantitatives. When treating of quantity, we have already said that it consists in number and dimension, in so far as some thing possesses such a quantity, that is, in the number of material things, and in the extension of the subject.[380] Here indeed we are not treating of abstract quantity, but of a quantity which causes a piece of wood to measure three feet, or that horses are five in number. Consequently, as we have said, we should call extension and number (considered from the concrete viewpoint) "quantitatives"; but this name could could be applied neither to time nor space; time, being the measure of movement,[381] re-enters into relation; and place, being that which contains the body,[382] consists of a manner of being, and consequently, in a relation. (So much the less should we call time and place "quantitatives," as) movement, though continuous, does not either belong to the genus of quantity. LARGE AND SMALL ARE CONCEPTIONS BELONGING TO QUANTITY.
