Ski-touring in Norway, Easter 2008

"Child and animal play because they enjoy playing, and therein precisely lies their freedom. Be that as it may, for the adult and responsible human being, play is a function which he could equally well leave alone. Play is superfluous. The need for it is only urgent to the extent that the enjoyment of it makes a need. Play can be deferred or suspended at any time. It is never imposed by physical necessity, or moral duty. It is never a task. It is done at leisure, during 'free time'. Here then, we have the main charasteristic of play: that it is free, is in fact freedom."

- Johan Huizinga (quote from book "How to be free" by Tom Hodginson)
