 Spinoza agrees with the Cartesian conception of body as res extensa (Latin, extended thing), i.e., things necessarily and exhaustively conceived through  extension.[1]  He was, like Descartes, a plenist, rejecting the intelligibility of a vacuum. Furthermore, we know from Spinoza's correspondence that he accepted nearly all of Descartes' kinematic views, that is, the laws he articulated describing the course of physical phenomena. He likewise agrees with Descartes that physical nature should not be conceived as a teleological system, and that appeals to final causes should be banished from physical theory.
