||The nature of the human mind is a central concern in all of Kant's major works. His view of the mind is shaped by two fundamental distinctions: (1) activity vs. passivity and (2) form vs. matter. The paradigmatic activity of the mind, for Kant, is judgment, which involves the unification of representations through concepts. This activity is directed at intuitions/sensations, which are distinguished by our passivity in receiving them. While both judgment and intuition involve certain forms, the latter is the source of all the matter of our experience. Judgments, for Kant, are essentially connected to self-consciousness. Kant gives broadly similar accounts of practical and aesthetic experience, in each case emphasizing forms that we actively apply to the passive elements of our mental lives.
