"When you start thinking about art and creativity, rationality is not big enough to contain it all. Otherwise you end up at a B.F. Skinner hypothesis where it is all purely to do with stimulus and response. B. F. Skinner actually put forward — and this is a measure of scientific desperation over consciousness — the idea that consciousness was a weird vibrational by-product of the vocal cords. That we did not actually think. We thought we thought because of this weird vibration caused by the vocal cords. This shows the lengths that hard science will go to to banish the ghost from the machine."
