Watching Shine last night, about the pianist David Helfgott who suffers from schizoaffective disorder, and talking about Daniel Johnston (schizophrenic and bipolar, among a myriad of other things, I would imagine) on the "What are you listening to" thread, got me to thinking about repressed beauty of feeling and passion that manifests in profound art.
They have a block on their interpersonal expression, and the only way to get across how they feel is through music. It's tragic yet beautiful. Poe should have written a poem about it, or perhaps Poe is one of them.
The interesting thing about Daniel and David, is their relative normality in their youth, and the possibility that their disorders are heavily pathologically influenced (religion, social suppression). And as the disorder has progressed, it has become cumulatively self-inflicting.
In David Helfgott's situation, it seemed that his father's desire to isolate and push his son into becoming a virtuoso pianist (projecting dreams) created a self-fulfilling prophecy, and indirectly lead to his institutionalization.
Here's that article on the upsides of being down, again:
