Eudaimonia THIS IS AN ANCIENT GREEK WORD, normally translated as 'fulfilment', particularly emphasised by the philosopher Aristotle. It deserves wider currency because it corrects the shortfalls in one of the most central terms in our contemporary idiom: happiness. The Ancient Greeks resolutely did not believe that the purpose of life was to be happy; they proposed that it was to be fulfilled. What distinguishes happiness from fulfilment is pain. It is eminently possible to be fulfilled and, at the same time, under pressure, suffering physically or mentally, overburdened and in a tetchy mood. Many of life's most worthwhile projects will, at points, be quite at odds with contentment, but may be worth pursuing nevertheless. Henceforth, we shouldn't try to be happy; we should accept the greater realism, ambition and patience that accompanies the quest for eudaimonia.
