 While there may be a variety of reasons for reading Kant as endorsing Conceptualism, so understood, two stand out. The first is philosophically motivated by the position that sense experience can play a rational or justificatory role with respect to belief or judgment only if such experience possesses conceptual content (see  §5.1  for discussion). Second, many think that the only plausible way of interpreting Kant’s argument in the Transcendental Deduction of the Critique of Pure Reason requires that he endorse Conceptualism (see  §5.5  for discussion).
