Technical Reason, Practical Reason, Morality

As previously proposed, 'Technical Reason' recasts empirical causal knowledge for use.  Hence, Technical Reason is the source of maxims, i. e. it recasts 'A causes B' as 'A is a means to B'.  Now, insofar as the exercise of human skill is the Ultimate Purpose of Nature, as Kant argues in the 3rd Critique, all of Nature is potential raw material for Technical Reason.  However, included in Nature are physical human beings, which are, thus, likewise, susceptible to the healthy exercise of Technical Reason.  It is this susceptibility that Pure Practical Reason implicitly corrects by conditioning maxims, and explicitly addresses when it requires that humans not be used as mere means.  In other words, his Moral doctrine is primarily a product of an internal self-modification of Reason, and not a marshaling of Reason against indifferent or hostile external forces--self-love, the senses, etc.--as the conventional dimension of his exposition often seems to suggest.
