In my recent Brief Report [Phys. Rev. A 32, 1239 (1985)] it was pointed out that the widespread confusion over the nature of material frame-indifference (MFI) is due to the attempts to justify this useful approximation by an appeal to the correct, but irrelevant, idea of material behavior being independent of the motion of an observer. The Comment by C. G. Speziale does not address this point, but concentrates instead on discussing how good an approximation the MFI is. This discussion is criticized below.
