Personally I would stick to the word "pleasure" where DO uses hedone, and consider using "satisfaction" where he uses eudaimonia. But I much prefer Don 's "well-being" to satisfaction: well-being seems much more complete to me, if that makes any sense. As for substituting satisfaction for pleasure, I can't imagine running around and shouting to everyone about satisfaction! Also, I think over time we've been getting to a more specific definition of "pleasure" as one part of the faculty of feeling…
