Subjective, Intersubjective And Objective

Subjectively, each sighted person sees colors.

We learn words for colors when we learn to speak.

Thus, we learn to recognize and respond appropriately to particular colors.

Stop at red lights; go at green lights; people with pink skin and coffee with milk in are "white."

 

Intersubjectively, we agree about colors.

Grass is green; the sky is blue.

Objectively, scientific instruments detect and measure electromagnetic wavelengths.

Electromagnetic radiation causes color perceptions in sighted organisms.

Longer wavelengths correspond to red; shorter to blue.

Cause and effect exist and are not identical.

If only the objective existed, the nothing would be subjective.

Then there would be no distinction between subjective and objective.

 

Neurons cause consciousness.

If only neurons existed without any effects, then there would be no consciousness.
