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.

The thing about illusions is that they mislead the viewer, by definition.
By your definition perhaps, but not by anyone else's. Here it just means not quite as it seems. It certainly has nothing to do with misleading anyone about what is the colour of a bus.

What is the difference between "not quite as it seems" and "misleading"? :scratch:
