Passion, Reason, Adaptation

Kant's response to Hume regarding the relation between Passion and Reason is more radical than it is often taken to be.  The main point of that response is that Hume's thesis applies to Instrumental Reason, i. e. to the use of Reason in determining the Means to Ends, but not to Pure Practical Reason, in which Reason functions to mediate interpersonal relations.  The specific decisive evidence, according to Kant, is that this Reason can control the Passions, which prompts Schopenhauer, implicitly defending Hume, to argue that Kantian Reason has ulterior passionate motives.  However, Kant's Copernican Revolution suggests that at issue is more than an internal Psychological struggle.  For, from an Ecologic perspective, Kant, perhaps inspired by the emergence of Automation, detects that the basic Human Experience is undergoing a more radical transformation: from Adaptation-To to Adaptation-Of, with Reason emerging as Technical Reason.  However, because of his Theological commitments, in this pre-Darwinian period, he can develop his insight only in terms of a Psychological struggle between Heteronomous and Autonomous influences, i. e. between Passion and Reason.
