1) I am uncertain I am right about this, but [early] Heidegger appears to view death and demise as separate, but essentially linked in that both refer to the end of life. Whether he means “impossibility of Dasein” to refer primarily to something coinciding with biological death or simply emphasizes it, I think the emphasis is misplaced. Any deep change in Dasein’s orientation to being-in-the-world is a kind of death, and it is here that the religious conceptions of death-and-rebirth have their sense. Anxiety occurs whenever Dasein is faced with a future transformation that it cannot foresee with any degree of specificity, and the anxiety intensifies with the degree of impossibility of foresight. An impending religious rebirth is existentially equivalent to biological extinction.

2) Heidegger (appears to) see Dasein in strictly individualistic terms. I believe Dasein exists collectively, and that even an individual comprises a plurality of Daseins. And I believe what can be said of individual Dasein can be said of supra-individual Dasein. Most importantly collective Dasein can be authentic or inauthentic. Heidegger’s factical situation misled him to believe collectivity is essentially inauthentic, and therefore always “the They”. It might be that any Dasein will eventually discover a limit to the being in which it can participate, and all beyond that point it will encounter They, but I deny this boundary is necessarily that of the individual. Unfortunately, this denial is based entirely in faith, and not in experience. My personal experience confirms Heidegger’s views.

Both of these points have deep practical consequences for how I live in the mundane world, the hopes I hold for it, and my strategies for acting in it.
