THE SKULL contains the brain, but it doesn’t contain the mind. We walk around thinking our minds are in our heads, but the mind is only an inner space of the body metaphorically. Eyeballs aren’t peepholes brains peek through. Movies aren’t projected in some cinema between our ears. It’s pitch black inside there every second of every day. Even in full sun, our brains are always dark. Our heads are light-tight, even when our eyes are open.
