I think Art is the social statement of the solitary human- the oyster making a pearl in response to the sand grain that got in it's shell.Balinese culture doesn't have the distintion between Art and craft that wetern culture traditinally has had. The Balinese also have ritual performance in which they act out,give expression to their scary monsters from the Id,seemingly making it much less likely that they project them onto each other,or better yet the Other as we in the west do so much. This manifests in everything from rejection and mistreatment of kids who are different, to rascism and xenophobia ,to polarized tribal politics , to War. In western culture the outsider status of artists ,makes it more likely that the artists have enough perspective to reflect something meaningful back into the group,if it cares to notice.Van Gogh only sold one painting in his life .I think the misfit thing starts in school which tends to cultivate a sort of attenuated cognitive dissonance .We are taught that we are free,freer than any one else in the world has ever been,and that we're all equal.Then we're forced to conform by sittng still in one place all day,learning what we're supposed to,basically punished if we don't learn it,on schedule ,and then we must compete with each other(even tho we're spozedto be equal) for who gets the privileges,ie getting into the best colleges,getting the best education allowing one to get prefered employment,afford to buy the best houses and consumer goodies.Cognitive dissonance craves resolution -some find it in actively competeing,and getting the goodies-some by rebellling ,and getting negative attention-Some just don't accept,or even understand the terms of the game and dabble in creating more interesting worlds for themselves . I think the term self esteem is partly misleading,because what the pressure for social conformity often causes people to do ,is to create a social persona.Persona is the name for the masks worn in the Roman version of Greek theater .Persona,personality is a mask for playing a role. I think social conformity involves convincing oneself that one is the character,by convincing others.Some of us have trouble with this,or aren;t convinced that they are the character they portray. This could be low self esteem,or I could call it ,not getting juicy feedback for the characdter one portrays.The Jungians use the term Individuation ,for the procerss of forming a sense of self that includes the whole psyche,not just the social surface.I think the misfit artists in our culture are the ones who have access to the deeper subconscious parts of the psyche,which are mostly suppressed when they can't be ignored in "normal "life,thus we can give expression to a deeper richer sense of the moment, of the experience of living.We can bring the best of our solitary deep selves and imaginations to the group in a way that enriches everyone,and strikes a balance between self and group that doesn't require suppression of the self. As a child the outsider thing was painful,but now I feel almost like I escaped prison by not being able to fit in. BTW there is a huge Poetry Slam movement going on inthe US .I'm not that interestsed in poetry as a competitive performance art myself,but the ancient Greeks were,The Laureate was the winner of a huge competition that drew thousands of spectators and was fiercely competitive.
