Abstract
Heidegger’s thought, particularly in the middle and late periods, is often characterized—and criticized—as historicist. The strands of reflection constituting Heidegger’s historicism lead to the core of his most profound contributions to fundamental questions concerning the structure of Being. We should expect therefore that understanding this historicism will be as complicated as it is important, and that suitable criticism of his position should be attempted only when this understanding has been approximated, if not achieved.
