Abstract
In the "Transcendental Aesthetic" of the Critique of Pure Reason, Kant offers an argument for transcendental idealism. This argument is one focus of the longstanding controversy between "one-world" and "two-world" interpretations of the distinction between things in themselves and things as they appear. I present an interpretation of the argument of the "Aesthetic" that supports a novel "one-world" interpretation. On this interpretation, Kant is concerned with the mind-dependence of spatial and temporal properties; and with the idea that space and time can be identified with mental objects. I end by arguing that, for Kant, even on a "one-world" interpretation, we do not know the nature or even the existence of mind-independent things
