Sacks on the brain!
The facts explained in this video are
fascinating! Blind people seeing realistic scenes or figures? That's
amazing! Indeed, these results help us answer a question put by
Breuer, in an article co-written with Freud: Can we live without the
use of a sense (and more generally, what is the role of senses)?
Sachs gives a scientific, empirical answer to this metaphysical
question: no, we cannot! We might be blind, yet the parts of our
brain related to vision work. Hallucinations have huge psychological
importance, in so far as they reveal what we WANT to see or the desires
deep in our minds...
