Isn't the reason why "Dasein dies, but animals perish" the presumed
fact that animals don't have any direct knowledge of their own eventual
deaths, whereas human beings are given death in the form of the
certainty of their mortality? No givenness of death, no Being-toward-
death, no differentiation between authenticity and inauthenticity.
What's unfortunate about this?
This of course assumes animals don't know they're going to die, which
is problematic especially in the case of 'higher' animals. One thinks
of elephant post-mortum 'rituals' and the like.
