"I see art as the continuation of the instinctive drive to play.  It is these instincts, I believe, which have led to the evolution in modern mammals of more sophisticated levels of intelligence.  The correlation in species such as dolphins, whales and primates, between extended periods of neoteny and increased intelligence and communication is directly causal, in my opinion.  I believe the act of playing is the process by which the self learns about itself.  It is a process which allows individuals to develop and test a rich range of responses to challenges and opportunities with which one is confronted.  We are the games we play."
