As the subject’s intensity of self-consciousness increases, so does its pain and anxiety in the face of death. This causes hopelessness and despair which may or may not lead to a total devastation of the project of inverting and putting into the spotlight the nothingness at the centre of the subject. Heidegger repeatedly puts all this down in Being and Time when he says that “being-towards-death is angst.” One cure for expelling anxiety has been to believe in god, any other metaphysical construct, or in some cases it has even taken the form of a materialist system of thought; in all these cases, however, an escape is seen as a solution when in fact it is the problem itself. For our concerns, an escapist attitude, and especially one that tries to go beyond the physical, does not work at all, for what we are looking for is a way of learning to make use of the reality of the death drive as an interior exteriority constitutive of the subject as a creative agent.
"...an interior exteriority constitutive of the subject as a creative agent."
You mean it is OK to be anxious? I have found that to be a "hard-sell." We are taught that anxiety is not just painful but it is abnormal. We'd rather have the disability where we are unable to feel any pain. Or maybe there is a distinction between necessary and unnecessary anxiety?
PS. Might it be that the poetic invention of "beyng" and "differance" are aids to mindfulness?
