 Kant was familiar with arguments of the kind that we just saw Descartes mount (chiefly from similar reasoning in Leibniz and Mendelssohn) but he was not impressed. For Kant, that consciousness is unified tells us nothing about what sorts of entity minds are, including whether or not they are made out of matter (1781, chapter on the Paralogisms of Pure Reason). He argues that the achievement of unified consciousness by a system of components acting together would be no more or less mysterious than its being achieved by something that is simple, i.e., has no components (1781: A352).
