Yet is it really so obvious that the tennis or golf professional is a more useful member of society than the wealthy amateurs who devoted their time to perfecting these games? Or that the paid curator of a public museum is more useful than a private collector? Before the reader answers these questions too hastily, I would ask him to consider whether there would ever have been golf or tennis professionals or museum curators if wealthy amateurs had not preceded them. Can we not hope that other new interests will still arise from the playful explorations of those who can indulge in them for the short span of a human life? It is only natural that the development of the art of living and of the non-materialistic values should have profited most from the activities of those who had no material worries.
