@Fil Albuquerque,
FBM believes his body is separated from his mind, but also that his body can think by itself without involving the mind. It's a bit of a strange mythology indeed, one that may lead to schyzophrenia, but it allows him to entertain the illusion that he doesn't need beliefs: whenever he acts based on a belief, it's his body doing it..... not his mind. Another artificial segmentation he uses to maintain the illusion, is between his normal & daily self, who acts just like everybody else based on all sorts of assumptions and beliefs -- e.g. in the existence of the universe, in the love of his dog, or in fiat currency (paper money) -- and his philosophical self, when he sits in his armchair at night to pounder what if the universe did not exist.
IOW, his 'pyrrhonism' has not application whatsoever in real life. It's just a funny way to pass time off.
