Reason, Choice, Bi-Heliocentrism

Silber interprets Kant as effecting a Moral 'Copernican revolution', i. e. as inverting the traditional concept of Reason as conforming to independently set 'goods'.  His analogy, thus, abstracts from the "motions" that Kant ascribes to the source of Reason, thereby falling short of the 'Copernican revolution' that has been proposed here--from passive Subject to dynamic Agent.  Accordingly, Silber settles for Heliocentric imagery, with Pure Practical Reason as the 'Sun'.  Now, as has been previously argued, Silber fails to make the case that Freedom of Choice is derived from Pure Practical Reason.  Hence, a more accurate characterization of that imagery is 'Bi-Heliocentric', because that failure leaves the model with two 'Suns'--Pure Practical Reason and Freedom of Choice.  In that respect, Silber's representation of the outcome of Kant's effort to reconcile rational morality and popular morality, is accurate.
