Dieter Henrich's writings on Immanuel Kant's philosophy have set new international standards in the interpretation of Kant. Henrich's method of argument-analytical reconstruction is paradigmatic in that it presents Kant's main questions and lines of reasoning, identifies unclear and contradictory statements and translates them into a precisely comprehensible sequence of arguments. At the same time, Henrich works out the starting points for corrections, modifications and shifts in fundamental philosophical questions in the Kant reception of German idealism. His interpretations of Kant's philosophy were taken up early and intensively in the English-speaking world. As a result, he triggered lively discussions that continue to this day, in which efforts to find an appropriate interpretation of Kant are combined with systematic questions about the structure of epistemic and personal self-consciousness. Henrich conceived the two volumes himself. The contributions in the first volume are devoted to an understanding of the epistemological and ethical foundations of Kant's system of philosophy; the second volume comprises the writings on the transcendental deduction of the pure concepts of understanding, the conceptual elucidation of which Henrich regarded as his most original achievement within Kant research. The edition contains an unpublished exposition of the Transcendental Deduction in 12 steps, The edition contains an unpublished presentation of the Transcendental Deduction in 12 steps, a text on the 'Composition of the Critique of Pure Reason', previously only published in Russian, and an epilogue by the author, which he wrote just a few weeks before his death in December 2022.
