Mortimer Adler,
Labor, Leisure, and Liberal Education
“ The results of leisure activity are two sorts of human excellence or perfection: those private excellences by which a man perfects his own nature and those public excellences which can be translated into the performance of his moral or political duty—the excellence of a man in relation to other men and to society. Hence I would define leisure activities as those activities desirable for their own sake (and so uncompensated and not compulsory) and also for the sake of the excellencies, private and public, to which they give rise. ”
