In their recent paper and the associated Response to this Comment, Tuckerman {ital et al.} dispute the form of the Liouville equation, as proposed by Liouville in 1838. They go on to introduce a definition of the entropy which is at variance with Boltzmann{close_quote}s H-function and with Gibbs{close_quote} definition of entropy. They argue that their {open_quotes}entropy{close_quotes} is a constant of the motion, equal to its initial equilibrium value regardless of the imposition of external fields. We argue that the analysis of Tuckerman {ital et al.} is incorrect and that issues raised by Tuckerman {ital et al.} are not at all new but have already been correctly incorporated into nonequilibrium statistical mechanics. {copyright} {ital 1998 American Institute of Physics.}
