Persistence in Being and Adaptation

One of Spinoza's Postulates is "The human body stands in need for its preservation of a number of other bodies, by which it is continually, so to speak, regenerated." However, he does not explore the relation of this Postulate to "The human body can move external bodies, and arrange them in a variety of ways", i. e. he does not explore how the latter capacity serves the former need.  Nor does he incorporate the two of them into his fundamental principle, the endeavor to persist in one's being.  A concept that can mediate that incorporation, one that emerges two centuries later, is Adaptation, thus revising the principle as, e. g. 'the endeavor to persist in one's being via Adaptation', which expresses that interaction with external bodies is essential to that persistence.  Now, the second of the Postulates signifies a cardinal distinction--between Adaptation-To those bodies, and Adaptation-Of.  One Philosopher who recognizes that distinction is Kant, who contrasts the conformity of Mind to Object, and the conformity of Object to Mind, but restricts the recognition to Epistemological relations.  The distinction is potentially decisive to Spinoza's doctrine--an Active relation to external bodies vs. a Passive relation to them, a contrast that is at the heart of what he is cultivating.  And, as Kant characterizes it, the transition from the latter to the former constitutes a 'revolution'--from Homo Sapiens, to Homo Techne.  So, the incorporation of the concept of Adaptation into Spinoza's doctrine can clarify its primary ambition.
