Will, Motion, Rest

According to Spinoza, Extension consists of two primary characteristics that he sometimes calls 'infinite modes'--Motion and Rest. Now, insofar as Extension is a dynamic divine Attribute, the derivation of Rest from it is unclear. Furthermore, the concept does not explain how Motion can become Rest, or vice versa, the former of which is entailed in any completion of creativity, e. g. the completion of the creation of a finite Mode, and the latter of which is entailed in divine self-causality, i. e. in which God sets himself in motion. In contrast, here, Motion and Rest are conceived as abstractions from more primitive originating and terminating processes, i. e. from the Material Principle and the Formal Principle, respectively, of the system, e. g. Will and Comprehension in the context of personal experience. Accordingly, Motion and Rest are just as much infinite modes of Spinozist dynamic Thought as they are of Spinozist dynamic Extension.
