Abstract
When exposing and interpreting Kant’s transcendental Deduction (in Der philosophische Kritizismus, Geschichte und System, Volume 1), Riehl employs the same vocabulary used by Kant himself, but he attributes a realistic meaning to some of Kant’s technical expressions. Thus, in order to properly understand his view of the Deduction it is convenient to grasp Riehl’s realistic assumptions, especially his theory of sensation and his statement that pure concepts cannot be separated from their objects but by means of an operation of abstraction. Accordingly, in the present paper, I examine Riehl’s theory of sensation and his explanation of the mentioned operation of abstraction, before exposing, in the last chapter, his account of the Deductions A and B contained in the Critique of Pure Reason.
