Transcendental Knowability and A Priori Luminosity

Abstract This paper draws out and connects two neglected issues in Kant’s conception of a priori knowledge. Both concern topics that have been central to contemporary epistemology formal particular: knowability luminosity. Does Kant commit some form principle according which certain necessary truths are knowable beings like us? luminosity which, if subject knows , then they can know ? I defend affirmative answers both these questions, by considering the special kind modality involved conceptions possible experience essential completability metaphysics, argue his combination principles leads into difficulty.
