The kinetic approach of Boltzmann to non-equilibrium phenomena in dilute gases is briefly discussed. Bogolubov's generalization of Boltzmann's method to dense gases is presented. The essential difficulties encountered in this attempt are exhibited and the impossibility of a straight-forward generalization of the Boltzmann equation to higher densities is concluded. Some hydrodynamical consequences of this are mentioned.
