When I play a video game I am conscious. Presumably I would still be
conscious even using a fully immersive system like the vertebrain system
described on this page ( http://marshallbrain.com/discard8.htm ). If that
is true, and you agree with me so far, do you think a brain in a vat (
http://en.wikipedia.org/wiki/Brain_in_a_vat ) would be conscious? Would it
be conscious whether its optic nerve were connected to a webcam or connected
to the TV/OUT port of a video game? What about a human brain that spent its
whole life as a brain in a vat from the time it was born (assuming it were
given a robot body for input, or assuming it was given a computer game
realistic reality)? I am curious at what point you think the consciousness
If you agree that the brain in the vat would be conscious in all cases (even
when given input from a video game) and you agree that a robot body with a
software brain would be conscious, why would it stop working when you put a
software brain in the same position as the brain in a vat?
