This article is inserted in the theoretical framework of current and contemporary controversies around the discussion of the Heideggerian categories. It aims to expose the meaning of the notions of event and difference, since these notions have a problematic character, because they can not be substantiated but are founded on the abyss. In the conclusions, we present an appropriate conceptual framework to think about the event and the difference based on the interpretation of the Zwischen regarding its tensive status.
