Critique of Pure Reason Lecture notes, January 29, 1997: Transcendental Deduction I The production of the list of pure concepts of the understanding (categories) from the table of judgments is known as the "metaphysical deduction." It has been roundly criticized as being ad hoc , no the product of a "single principle," as Kant hand maintained. Nonetheless, we shall try to see what the principle is, in the hope that the discovery of Kant's strategy can shed some light on his overall treatment of the categories. The key point of similarity between judgments and concepts is that both introduce unity into representations. A judgment subsumes an intuition under a concept or places one concept in the sphere of another. Thus in a categorical judgment, the subject is included in the sphere of the predicate concept. In general, Kant called the unity produced in judgments an "analytical unity," and held that there are twelve forms by which the unification takes place.

Unformatted text preview: Although Kant's target is pure concepts of the understanding (concepts which have their origin in the understanding itself), I will begin my discussion of the unifying function of concepts by showing the unity in empirical concepts. When I am given a number of intuitions, I can discern in them some common characters ("marks," or Merkmale ). A number of characters together make up the intension of a general concept. In Locke's example, the characters hard, malleable, ductible, fusible and others go together to make up the concept of metal. We form the concept by observing objects sharing these characteristics. The unity provided by the concept is both that of the intension (the sum total of the characters making up its intension) and that of the extension , the sum total of intuitions which fall under the concept (my watch, a plate in my study, my car's engine, etc.). Note that both the intension and extension are elements given in experience....
