Regardless of any misconceptions, I thoroughly enjoy the art of most proper outsider artists. I actually chuckled that Wesley Willis was on Wikipedia's list of outsider artists. I love me some tunes about whoopin Spiderman's ass.
On slightly different note, I am also fascinated with the illustrative works found in Carl Jung's Liber Novus now known as The Red Book. Like most early "Outsider Artists", he would simply illustrate the crazy shit he saw in the state of psychosis. Only thing was, he was a leader in the field of psychotherapy, therefor his "unconscious" was at his control to capture in an organized manner.
Most of you have probably heard about this guy in a psychology class or know him at Freud's pupil. The guy was a pioneer in psychological studies. Being the theorist behind the complex, collective unconsciousness, and even word association. He was also an artist of different sorts. His artistry which I find most interesting as I mentioned before, are the illustrations within The Red Book. This dude would hallucinate and suffer from elaborate illusions depicting apocalyptic-like situations. As someone who had studied the human mind for years, he confronted his psychosis and begun a long series of self examination. He believed the only way to capture his visions and dreams was through symbolic imagery, so he would paint.
