Though time does not permit me to explore this fully immediately, or really in the near future, this is a question that often enters my mind.
Understanding that knowledge does not invariably make one happy, could it be possible that the ancient thinkers who had such objective views on happiness were not themselves truly happy?
In the future, I’ll add snippets of philosophical tracts related to this subject (e.g. Aristotle’s Ethica Nicomachea, Plato’s Republic, Epicurus etc.) with some comments alongside. Though our knowledge of the characters of these men is rarely reliable, I think it’d be an interesting course of investigation regardless.
