 The fact that we are capable, through reason, of thinking infinity as a whole, “indicates a faculty of the mind which surpasses every standard of sense” (§26, 254). While Kant’s discussion of the mathematically sublime mentions the Pyramids in Egypt and St. Peter’s Basilica in Rome (§26, 252), it is not clear that these are intended as examples of the sublime; and Kant claims explicitly that the most appropriate examples are of things in nature. More specifically, they must be natural things the concept of which does not involve the idea of a purpose (§26, 252–253): this rules out animals, the concept of which is connected with the idea of biological function, but it apparently includes mountains and the sea (§26, 256).
