Abstract
In this article I claim that distinction should be made between an "early Derrida" and a "later Derrida," similar to the one made between Wittgenstein of the Tractatus and Wittgenstein of the Investigations, or between Heidegger before the Kehre and Heidegger after it. Acceptance of such a distinction enables us to understand Derrida's teachings more clearly, to solve a disagreement in Derrida scholarship, and to understand his deconstruction as less contradictory. I shall also explain the reasons for, and causes of, the change in Derrida' teachings and distinguish between those aspects that changed and those that did not.
