The paper proposes an interpretation of the Table of Nothing in the Critique of Pure Reason, which relates the table closely to the tables of the categories and the principles of the pure understanding. The paper argues that the fourth type of nothing on Kant’s table should not be identified with the impossible of the rationalist tradition, i.e. with the object of a contradictory concept. The break between Kant and his rationalist predecessors with regard to the question of possibility, or to the distinction between something and nothing, is concluded to be more radical than often assumed.
