If your "inner mental world" is to be dismissed as "spooky", how do you think we evolved a sense of colour discrimination?


Simple, the functional aspects of colour discrimination are beneficial traits. The interesting question is why we also evolved a subjective experience of colour qualia to go along with it, which we could call consciousness of colour discrimination. That has some additional benefits.

Subjective experience is the only way we see colours, is it not? Also, I was the one who first mentioned the evolution of colour discrimantion as a beneficial trait (years ago), so you can't use that against me.


I should think discriminating colours is done by the networks of cells in CNS, not by a homunculus observing qualia. We can make instruments to discriminate colours and they don't need qualia. I think the idea that we can discriminate colours by having conscious experience of redness etc. is highly dubious.

I should think you have it backwards. You experience seeing red because your brain has discriminated a colour and made a conscious event to suit.
