"...the power to know leisure is the power to overstep the boundaries of
the workaday world and reach out to superhuman, life-giving existential
forces which refresh and renew us before we turn back to our daily work.
Only in leisure ... man may escape from the 'restricted area' of that
'latent anxiety' which a keen observer has perceived to be the mark of
the world of work, where 'work and unemployment are the two inescapable
poles of existence." - Pieper, Leisure, IiI
