Mr. Spock would wish someone farewell by saluting them and saying, “Live long and prosper.” Other Vulcans or those in the know might respond, “Peace and long life.”
Things go in cycles, and we’ve been hearing a lot about “flourishing” lately. I’m a bit tired of it, frankly, and am making a plea for speaking about “prosperity” instead.
At least for today, that seems appropriate (and as long as we remember that, as the preacher of true prosperity put it, “Life does not consist in an abundance of possessions.”).
