 Another, related difficulty of self-interpretation concerns the historical transmission of interpretations. In this, Heidegger maintains that, as interpretations of existence are passed down from tradition, the “original sources” of concrete, existential concern, come to be covered over (Heidegger, Ontology, 59). Indeed, for this reason, Heidegger calls for a “destruction” or, perhaps, ‘de-structuration’ (Destruktion) of interpretations of being and the being of existence that have been passed down from the history of Western philosophy (see Heidegger, Being and Time, §6). This, to be sure, is a call that has important implications for the study of the history of philosophy, one that has been influential for philosophers such as Jacques Derrida, John Sallis, and Claudia Baracchi.
