eudaemonism
A philosophical notion, or system of ethics, which measures happiness in relation to morality.
countable, uncountable
Whether it be hedonism, pessimism, utilitarianism, or eudaemonism, all those modes of thinking which measure the worth of things according to pleasure and pain, that is, according to accompanying circumstances and secondary considerations, are plausible modes of thought and naivetes, which every one conscious of creative powers and an artist's conscience will look down upon with scorn, though not without sympathy.
Where it comes from
Borrowed from Ancient Greek εὐδαίμων (eudaímōn, “having a good genius, happy, fortunate”).
