Massage replaced by a passive sort of callisthenics. Nurse moves my limbs for me. This made me realise how little I know about “my will.” I want to move a leg. Then I’m aware of its moving. But what moved it? At what point does the sum of anonymous electric impulses + twitching muscles become me? Can I rightly call that force “I”? What’s the difference, regarding my participation, between the nurse’s moving my leg and the leg’s moving “on its own”?
