The demon has to find out which corpuscles are moving fast and which are not. In gaining this information he increases his entropy, and voila! calculations show that the entropy the demon gains is equal to the entropy the gas system loses by his ministrations! No contradiction. This is a well-known result in modern thermodynamics.
