The Stone (Lawrence Berger) on presence
We have come up against a deeply ingrained view of what it is to be a human being (which lends credence to views that our experience ultimately does not matter), which is that subjective experience takes place in a private realm that is cut off from the rest of reality. But Heidegger does not even make the distinction between the mental and the physical; for him our experience is an event in the world. The experience of the stone that I come to is part of the process of its manifestation in all of its possibilities. In this manner we are intimately related to the stone in our worldly presence, which is the site of its more profound manifestation. The claim is that the being of the stone itself is not independent of such an event.
