Reason and Causality

Without causal efficacy, the ideas of Reason remain Theoretical and regulative, not Practical and constitutive.  Now, while Kant demonstrates that it is not impossible that Reason can be a cause, and asserts that it is a cause, he not only does not explain how it is a cause, but insists that the impossibility of such an explanation is a virtue.  However, that immunization against the demand for an explanation is based on two premises--that Reason is supernatural, and that its causality is of the Efficient category.  In contrast, if, as previously proposed here, Reason is fundamentally proprioceptive, and its causality is of the Formal variety, then its efficacy is not only a plain fact of experience, but one that can be explained.
