I'm not sure if I've redefined it, but I've been encountering terminology that
better expresses my thoughts. Originally, I would have stated the path to
happiness would be to "behave honorably", and I still believe that is correct.
Along similar lines, in Adam Smith's "Theory of Moral Sentiments", it is
not enough to be loved, but to be a lovely person -- i.e. worthy of being loved.
The Stoics replace the term 'happiness' with eudaimonia, and argue
that only moral virtue and wisdom are necessary, which may be an ideal too
difficult for most of us to attain to "live in accord with nature".
I've been impressed with Adam's Smith's 18th century knowledge of Stoicism
and implicit critique of it in his book. To the extent that he builds on that basis
is his insistence in behaving with "propriety", which I don't think the Stoics were
interested in.
It might be debated that moral virtue may not make automatically make you
a happy person, but all paths to happiness appear to require virtue as a
prerequisite.
