My problem with hedonism, or decadence, or any mode of existence that could be described as self-serving, is that I could not be convinced, even if I were an atheist, that living for one’s pleasure alone is an actual form of happiness, neither for those around you nor for you yourself. Which, in a paradoxical way, would mean that it is not self-serving at all. Or, anyway, would mean that it is self-defeating.
