The World According to Kant offers an interpretation of Immanuel Kant’s critical idealism, as developed in the Critique of Pure Reason and associated texts. Critical idealism is understood as an ontological position, which comprises transcendental idealism, empirical realism, and a number of other basic ontological theses. According to Kant, the world, understood as the sum total of everything that has reality, comprises several levels of reality, most importantly, the transcendental level and the empirical level. The transcendental level is a mind-independent level at which things in themselves exist. The empirical level is a fully mind-dependent level at which appearances exist, which are intentional objects of experience. Empirical objects and empirical minds are appearances, and empirical space and time are constituted by the spatial and temporal determinations of appearances. On the proposed interpretation, Kant is thus a genuine idealist about empirical objects, empirical minds, and space and time. But in contrast to other intentional objects, appearances genuinely exist, which is due both to the special character of experience compared to other kinds of representations such as illusions or dreams, and to the grounding of appearances in things themselves. This is why, on the proposed interpretation, Kant is also a genuine realist about empirical objects, empirical minds, and empirical space and time. This book develops the indicated interpretation, spells out Kant’s case for critical idealism thus understood, pinpoints the differences between critical idealism and ‘ordinary’ idealism, such as Berkley’s, and clarifies the relation between Kant’s conception of things in themselves and the conception of things in themselves by other philosophers, in particular, Kant’s Leibniz-Wolffian predecessors.
