Deprivation offers a plausible explanation for the badness of death, so fear is not unreasonable. But horror at the prospect of one's death is not just extreme fear because horror is structurally different than fear. Horror requires a different explanation. For Sartre, horror is possible only in unique circumstances. I argue that Sartre's view, when combined with the subjective incomprehensibility of one's annihilation, can explain horror and other negative emotions that are not contingent on deprivation. Further, I argue that while (...) fear can be reasonable if one's death will deprive, Lucretius's Symmetry Argument shows that horror is unreasonable. (shrink)
