This is exactly Chomsky’s point. Try to get through life considering the color of the traffic light you’re approaching as a subjective rather than objective fact.

To pick an example closer to the morality case: Hunger could equally be called a subjective phenomenon. Aliens may not experience anything like hunger. A rare genetic condition might produce a human who experiences escalating hunger as an escalating degree of pleasure.

But as humans making our way through the real world, we are forced by physical and anatomical reality to see the causes and consequences of human hunger as objective truths.
