Heidegger on Authentic and Academic Logic

Throughout his work M. Heidegger develops the theme of authentic logic contrasting it with the prevailing understanding of the character, essence and goals of academic logic. He pays special attention to the ontological justification of logic, the derivative nature of the truth, the subject-predicate structure of judgement, copula and derivation rules. He also focuses on the status of logical negation and the language ofsymbolic logic. M. Heidegger examines in detail the justificatory role of the law of identity, the relations of difference and the law of sufficient reason, and not just as logical principles but fundamental statements of logic. The conclusion of this paper is the understanding that M. Heidegger’s doctrine of authentic logic is a challenge to academic logic and a decisive step towards philosophical logic in the tradition of continental philosophy.
