Graham Bird Kant's account of mathematics in the Critique is not confined to his discussion of space and time in the Aesthetic; it is outlined also in the Analytic and in the Methodology. But the link in Kant's account between mathematics on one side and space, time, and perception on the other is one reason for my raising the question in this context. In whatever way his account of space and time relates to our phenomenology and perception, it includes also an account of an objective, a priori, mathematics. Another reason lies in my response to a common conviction nowadays that Kant's account of mathematics is so outdated that it has no value at all. Though the account I offer at some points goes beyond what Kant actually says, I want to explore aspects of it whichhave some connection with contemporary debates and may still have some value.
