> if we care about existing, our sole responsibility is to each other and ourselves The conclusion does not derive from the premise... I can care about existing in a hedonistic way and then responsibility in no way derives from my caring about existing. I’ll just do whatever I want to do and get the most pleasure possible while I exist, with nary a worry. Unless you mean “we” as in “all of humanity” and “existing” as in “humanity surviving”, but then I don’t see why we should assume this premise to hold. Most people don’t have the energy to care about the survival of their entire species, there are enough problems to deal with in an individual’s life.
