In the third Critique, Kant collapses his deduction of the universal validity of judgements of sublimity into his exposition of such judgements, a decision called into question by commentators. I defend Kant on this score, explaining how the exposition of judgements of sublimity serves as their deduction. Kant’s key move is his claim that natural objects are not, strictly speaking, sublime. I argue that ideas of reason, on Kant’s view, are the only truly sublime objects and show how this allows him to establish that the imaginations of all observers operate in the same way in experiences of sublimity.
