If there's one word that defines what the
Fellowship of Reason is all about, it is "eudaimonism."
Pronounced "yoo-DIE-mon-ism", it is derived from the Greek word eudaimonia,
which is loosely translated into English as “well-being."Although
you can find a variety of specific definitions (depending on which
dictionary you use), we like this one:
"A
theory that the highest ethical goal is happiness and personal
well-being."
- Merriam-Webster's
Collegiate Dictionary (2002)
Some
dictionaries include the phrase "through a life governed by
reason" or something similar.
In short, Eudaimonists are people who think
that they should make flourishing in this life, through rationality and
virtue, their highest priority.
