There is perhaps no part of Kant’s Critique of Pure Reason which has called forth such severe criticism as his deduction of the System of Categories in the Transcendental Analytic. I am not aware of even one among his many followers who holds to this part of Kant’s doctrine. And the reason for this disagreement is obvious. Kant’s deduction of his System of Categories is based on Formal Logic, the theory of syllogism, first laid down by Aristotle. Mediaeval scholars had (...) changed some details and partly systematized the subject. Kant himself had added some finishing touches to produce his famous number of a dozen categories, but the gist of this logical theory was the same as that found in Aristotle’s Organon. (shrink)
