  In Aristotle’s opinion, all actual matter exists with certain properties like dimension, quality (cold, warm, humid and dry) and weight. Crescas distinguishes between the different properties. In his opinion there are three different levels of material  existence.[22]  Matter in and of itself has no properties. The body is the unification of matter and dimensionality (i.e. matter in corporeal form). It is possible that a pure body without any other quality has actual existence. The third level of material existence is the unification of the corporeal form (matter) with some other unique form. This latter unification affords matter the additional properties of weight and quality.
