Vorträge. Teil 1: 1915–1932 (edited by Günther Neumann). This much shorter version was not included in these investigations. Heidegger’s extensive lecture manuscripts on the Satz vom Widerspruch (Principle of Non Contradiction, PNC)—based strictly on the extracted content. GA 91: 189-346. The PNC is treated not merely as a logical axiom but as a site where the fundamental structures of Greek philosophy, Aristotelian metaphysics, and the question of Being cross one another. Heidegger covers the Six Classical Determinations of the PNC. Discussions include Aristotle, Leibniz, Kant, Fichte, Scholastics/Suarez, Wolff, and he uses the expression "linguistic/semiotic norm" perhaps Husserl. Plus, Hegel. Heidegger’s own counter proposal that the PNC is grounded neither in “logic” nor in “objective being,” but in the existential disclosedness (λόγος) of Dasein. Auch muss auf Heidegger zurückgegangen werden! Note: this is not Standard English and it is mixed with Heidegger's German and Greek.
