Manson: My philosophy is: Don't think. I don't believe in the mind that you think with and scheme with. I don't believe in words.

Reporter: If you don't believe in words, why do you use so many of them?

Manson: Words are symbols. All I'm doing is jumbling the symbols in your brain. Everything is symbolic. Symbols are just connections in your brain. Even your body is a symbol.
