The inverted spectrum is a hypothetical concept that some people have a qualia which is symmetrically different for the colours in which other people see. It is considered an inverted qualia. It is unusual neural ‘wiring’; the retinal stimulation is systematically wired and induces light of any given wavelength which then generates one’s visual cortex the same way our neural activity is generated by the spectral inverse of that wavelength. …show more content…
Partial functionalism manages to maintain this conception of human beings as physicochemical system whose experience behaviour which is completely explainable, of course solely in physicochemical terms. David Lewis then goes on to claim that the qualia is nothing more than a particular neurophysiological state-type (Lewis, 1983). They are not a higher-level state-type whose, as Lewis stated, presence and causal efficacy in human beings are mysterious from the perspective of natural science (Lewis, 1983). Although, the concept of functionalism goes far beyond what has been written on this paper, in general a theory of mind should not be made solely on the concepts of seemingly obvious facts about our mental life, like assuming two separate people with different mental states is an absolute, non-population-relative
