On the Asymmetry between Twin Earth and Inverted Earth

A crucial disanalogy between Twin Earth and Inverted Earth undermines qualia-internalism. A recent transplant to Inverted Earth has been equipped with color-inverting contact lenses, so that she is unable to see the colors of objects whereas a recent transplant to Twin Earth can see twater. It is implausible to think that time alone could rectify this perceptual shortcoming – that the passage of time could alter the contents of her visual perceptions or the meaning of her color terms. Thus, the thought experiment does not refute the close tie between phenomenology and representation in the case of color.
