  A demonic being, introduced by Maxwell, to miraculously create thermal
non-equilibrium and violate the Second law of thermodynamics, has been among
the most intriguing and elusive wishful concepts for over 150 years. Maxwell
and his followers focused on 'effortless gating' a molecule at a time, but
overlooked simultaneous interference of other chaotic molecules, while the
demon exorcists tried to justify impossible processes with misplaced
'compensations' by work of measurements and gate operation, and information
storage and memory erasure with entropy generation. The illusive and persistent
Maxwell's demon fallacies by its advocates, as well as its exorcists, are
scrutinized and resolved here. Based on holistic, phenomenological reasoning,
it is deduced here that a Maxwell's demon operation, against natural forces and
without due work effort to suppress interference of competing thermal particles
while one is selectively gated, is not possible at any scale, since it would be
against the physics of the chaotic thermal motion, the latter without
consistent molecular directional preference for selective timing to be
possible. Maxwell's demon would have miraculous useful effects, but also some
catastrophic consequences.
