Heliocentrism, Reason, Empowerment

The Sun is central to human experience not only insofar as it enables visibility, but also insofar as it is source of physiological energy, i. e. via photosynthesis.  Thus, the Sun not only enlightens, but it empowers, as well.  Now, many of the Heliocentric interpretations of Kant's system, e. g. Silber's, recognize only the first as analogous to the influence of Reason on human experience.  But, that Reason is causal, which Kant labors at great length to establish, suggests that the second solar property is the more fundamental analogy in his doctrine.  So, the empowerment by Reason is the focal point of the Copernican transformation of a passive Subject to a dynamic Agent.
