Consciousness

Look at your right index finger. The physical space around you is a seething cauldron of electromagnetic radiation. Some of this radiation bounces off your finger and is focused on your retina. The wavelengths between about 400-700 nanometers stimulate your retinal cells. They constitute the visible light spectrum from violet to red.

Note well; your finger is a physical object in physical space and is still firmly attached to your hand. Your finger did not enter your eye, the light did. Retinal cells convert the electromagnetic energy of the visible light to nerve signals. Information about your finger is digitized into a staccato stream of nerve signals racing along the million fibers in each optic nerve, in total darkness.

The light did not enter your brain, the coded impulses did. The signals enter the amazing machinery of your brain and the next thing you know, a finger appears in your perceptual space.

This visual perceptual space is private. You are the percipient and your finger is the percept.

Is the perception of your finger inside or outside your brain?

NEITHER……………………...
