"For a society surviving to no purpose is one that makes no provision for purposeless behavior - that is, for actions not directly aimed at survival, which fulfill themselves in being done in the present and do not necessarily imply some future reward. But indirectly and unintentionally, such behaviour is useful for survival because it gives a point to surviving - not, however, when pursued for that reason."

(Alan Watts, The Book On the Taboo Against Knowing Who You Are, 1966)
