Inner Space

Since I have looked into Heidegger and Wittgenstein I have found that the main force they battle against is the idea of a mind removed from the public world. Before being exposed to these ideas I was a property dualist. Now that I have a more holistic view of the mind there are still some questions that bother me. In this public view of the world can we now address the idea of the inner space with more clarity? That is, can we return to the old epistemological questions without worrying that if we fail the solipsists win? We now know there is the world of our existence that we live in and deal with. But this picture does not address the sense of wonder that dualists like Descartes had about the way the senses and mind deal. When we go to sleep at night our minds enter a different kind of existence (though still laden with concepts and ideas of the public world). Our senses are giving us existence but what if we bracket them out? What is it that we are left with and how does it relate back to the public world. More importantly how does it relate to being?
