It is a curiosity to me--perhaps an odd part about positivism--that only what we know exists. But if someone rejects that, does that turn them into a mystic? Or is it at the point at which someone tries ot understand that unknown? Certainly an understanding transcendence isn't what turns one mystic, or else Aristotle is one too?
Hmmm… Has the positivist transcended the mystic objectively?
