Psychiatry's a young science. Yesterday's madman may be tomorrow's genius. Beethoven and Van Gogh were both a bit loopy. In my view, most madmen are remarkable. They're explorers, travelers beyond the rim of consciousness. Not surprising if they pick up a few bugs and get sick. That's all it is, madness. Mad just means sick. If you get fluid on the lungs it's pleurisy. If it's fluid on the brain, it's insanity.
