Abstract
A clarification concerning the solution of the initial-value problem for the propagation of light pulses in dispersive media is given. In a proper interpretation, this solution corresponds to two single pulses traveling in opposite directions. Furthermore, a critical review of important research related to Rubin's arguments but not mentioned by him in the preceding Comment [Phys. Rev. A 41, 1727 (1990)] is presented.
