Aristotle on Leisure

At a conference on ‘Leisure in Canada,’ held more than a decade ago at Montmorency in Quebec, a participant observed that ‘practically all writers on the subject take Aristotle as the point of departure in discussing leisure but seldom seem to move from that point.’ At first sight this statement may seem surprising. How is it to be understood? Certainly recent writers on leisure do in fact list Aristotle's conception as one of the significant positions on it.
