We imagine brains as stationary. Contemporary philosophers often use the metaphor of a “brain in a vat”, or something close to that. Brains do not have arms. They do not have legs. Thus we assume they do not move.
But this is stupid. Outside of purely instinctive, reactive physical behaviors, substantially everything we ever do begins as a thought–perhaps a thought following an emotion, but the thought is what leads to actual action.
Thoughts have patterns, just as our bodies have patterns. Moshe Feldenkrais said that every person has their own unique dysfunction. Only those who move perfectly all move alike. (And the Police State has of course seized on this–as they seized on the Killing Joke–to develop software that recognizes distinctive motor patterns in people, as an adjunct to facial recognition software.)
Minds, likewise, move well only when spontaneous, only when not jumping from box to box. Minds constrained may as well be suffering from paralysis. In an ironic twist, the legs and arms move just fine: only the mind is paralyzed.
Again, fatigue and bubbles involved. Use these ideas at your own risk.
