I will start giving a simple example. We have differentiated photosensitive cells ( cones ) in our eyes. Each type is sensitive to different luminous electromagnetic frequency. Unlike what some people think, these cells do not “read” the colour of the light rays. Colour does not exist in nature. It is a perceptual construct ( qualia ) of particular neuronal circuitries in our brains. It is how our brains interpret and translate to our consciousness different slices of the light spectrum. Since we are all allele mutants to each other in some set of genes or other, it is perfectly possible that, in some case, our QUALIAS ( the way we perceive the information coming from our senses ) are different ( or even radically different ). For instance, it is perfectly possible that a colour that I see as red, you see it as blue or some bizarre colour. But there is no way to realize this difference ( at least up to now ) because we use the same label of colour to the same object. We both call it “red” without realizing that internally we are seeing different colours. For instance, I might see a piece of meat as “red” and label it as “red”, but you could actually see it as blue and also use the label “red” because that is how you learned to label the colour of the meat, without knowing that you internally are seeing something very different from me.
