The conventional way of explaining Gibbs paradox as due to the distinguish-ability of particles has been challenged recently and a new fundamental definition for the entropy has been proposed that gives the same entropy for distinguishable particles as for indistinguishable particles. In this paper arguments are presented that strongly favor the conventional definition of entropy and its resolution of Gibbs paradox.
