 Three replies are available, then: (i) To insist that the visual intentional contents would not shift. Word meanings would shift, but it does not follow that visual contents ever would. (ii) To hold that although all the ordinary intentional contents would shift, there is a special class of narrow though still representational contents underlying the wide contents; sensory qualities can be identified with the special narrow contents. (iii) To deny that qualitative content is narrow and argue that it is wide, i.e., that two molecularly indistinguishable people could indeed experience different qualities. This last is the position that Dretske (1996) has labelled “phenomenal externalism,” though in our terminology that would have been “qualitative” externalism.
