It&#x27;s odd, I know, but entirely factual. All sensation, all your experience of anything ever is a processing <i>output</i> of your brain.<p>Certainly if you hit my hand with a sledgehammer i will scream about my hand hurting. But what has happened? Nerves depolarise, synapses communicate, a pattern of activity emerges in my brain. And as the conscious entity experiencing that pattern, i experience pain.<p>If my spinal cord is severed (and i survive otherwise intact) those signals never reach my brain, and i experience no pain. No physical pain as a direct result of your actions, anyway. I may still be annoyed :)<p>Your experience is 100% dependant on and exclusive to your brain, sledgehammer or no.
