The purpose of art is not to communicate a description of objective reality. It only works when it communicates, successfully and convincingly, one mind's perception of subjective reality to another--or to many others.

And to a very great extent, the process of creation itself is subliminal, automatic, outside conscious control. It is often rather chilling, when actually meeting an artist, to see how quite often they are very ordinary people, sometimes even rather unpleasant. It makes you wonder "how could that insight have come from that mind?". In the case of music, and especially drama and cinema, the artistic communication is collaborative, it involves the coordination of multiple artists, operating on many different levels. The final product somehow transcends the sum of its parts.

Maybe we're making it all up, and maybe its all nonsense, maybe there is no great hidden truth or insight, that we make it up in our own minds just to justify or explain the way it affects us emotionally. Maybe its all just bullshit.

But still, isn't it unexpected (and wonderful!) when someone elses bullshit can affect and move us so profoundly?
