 Kant’s rejection of Leibniz’s Principle of the Identity of Indiscernibles is related to his complaint that the Leibnizians treated perception and thought as a single representational faculty that was “logically” (by which Kant meant “qualitatively”) distinguished in terms of the clarity of the representation, rather than “transcendentally.” With their theory of a single cognitive faculty, Kant maintained, Leibniz and Wolff “abolished the distinction between phenomena and noumena to the great detriment of philosophy.” Leibniz treated the senses according to Kant as an inferior mode of cognition, the senses having only the “despicable task” of confusing and distorting the representations of reason (KRV B. 332).
