"Hedonism, pessimism, utilitarianism, or eudaemonism, all those modes of thinking which measure the worth of things according to pleasure and pain, ... are plausible modes of thought and naïvetés, which every one conscious of creative powers and an artist’s conscience will look down upon with scorn. ... We regard your seriousness as more dangerous than any kind of levity. ... Well-being, as you understand it—is certainly not a goal; it seems to us ... a condition which at once renders man ludicrous and contemptible."
