  Atomic physics allows the possibility of evolutions to states that would usually be characterised as having a lower thermodynamic entropy.  An exorcism of Maxwell's demon, therefore, cannot be taken to be the claim that this entropy cannot go down, as this is definitely possible.  Smoluchowski proposed, not an outright exorcism of Maxwell's demon, but an argument that Maxwell's demon could not violate a modified second law. He offered a modified formulation of the second law which states the demon is unable to reliably, continuously produce work. Such a demon, while not exorcised, might be considered “tamed”. A tame demon could produce (in the terminology of Earman and Norton (1998)) “straight” violations of the second law, but not “embellished” violations, where the straight violation is exploited in such a way as to reliably, continuously produce such work.
