Rational Ethics and Deontic Logic

As has been previously discussed, what begins as the development by Kant of a Rational Ethics, stops well short of Actualization, which would require an introduction of Technical Reason to explain how Reason can create behavior.  Instead, he introduces into the breach the concept of Duty, as part of his effort to coordinate Rational Ethics with conventional, Theology-based, Deontic Morality.  As a result, Obedience replaces Autonomy as the behavioral focus of his doctrine, and, hence, is the ground of Virtue.  Accordingly, to whatever extent Kant's Moral doctrine can be credited with pioneering more recent Deontic Logic, it is not on the basis of his Rationalist Ethics, which transcends the mere exercise of the so-called Practical Syllogism.
