Heidegger sees the term Ereignis explaining presence in its entirety without the need for a privileged ontological point. Everything that we witness is possible because of the appropriating event. We are not only talking about beings, the world and language here, but also about Being itself. Before introducing this concept, Heidegger speaks about the givenness of Being: "there is" (Es gibt) Being, he tells us. Ereignis is regarded as the source of this givenness: The appropriating event grants this givenness. It is, in turn, the source of language. Ereignis is that which allows language to be granted and for the human being to receive the grant, the listening and saying as disclosure.
With this new expression, Heidegger is trying to expose a dimension of Being that had been concealed until now. Being's occurrence, as well as the possibility of exposing it, cannot be explained in any other terms, not even those of the cause and effect.
