Will, Actuality, Actualization

In some passages, Spinoza defines the 'actuality' of a Mode as its endeavor to persist in its being, while in others, he proposes that it consists in a specific configuration of its various parts. However, he does not elaborate on the relation between these two characteristics, which must be more fundamental than that between Body and Mind in his system, because he ascribes the endeavor to the Body-Mind conjunction, and he proposes that Body and Mind are parallel composites. In contrast, here, exertion and structure are expressions of the two principles of personal experience--Will and Comprehension, respectively--the combination of which constitutes the process of Actualization. On that basis, the endeavor and the configuration of Spinoza's Modes are each a necessary, but not a sufficient, condition of actuality, i. e. of the product of Actualization.
