Centripetal, Centrifugal, Mind

As has been previously discussed, the repudiation of Geocentrism and Anthopocentrism, entailed by the Copernican discoveries, is preparatory to a replacement of Centripetal Geocentrism and Centripetal Anthropocentrism, by Centrifugal Geocentrism and Centrifugal Anthropocentrism.  In other words, the concept of humans as protagonists on a cosmic stage in a drama determined by impregnable Heavens, is replaced by that of humans as centers of action, with the Heavens an accessible destination, as history has proven.  Now, one set of inhabitants of the Ancient Heavens is Platonic Ideas, which are thus passively experienced, e. g. contemplated.  But Spinoza inverts that relation, with a concept of Mind that anticipates Brentano's Intentionality.  According to this concept, Mind experiences an Idea only insofar as it posits it, i. e. affirms it, which Spinoza ascribes to Volition, rather than to Brentano's Intention.  On this basis, Volition and Understanding are one and the same, in opposition to Descartes' contrary concept of their relation. Kant later briefly similarly posits the unity of Will and Reason, but squanders the opportunity to further develop the insight, and to perhaps extend his rubric 'Copernican Revolution' to that unity.
