Suppose your brain contained identical parallel circuits A and B, tied together at input and output, which could be switched on and off independently of each other. It would be difficult to do with biological tissue due to chaotic internal processes but more straightforward if you consider a digital implant. Obviously, if you switch A and B off together you will lose all the functionality of the circuitry. But if you switch off either A or B, you will notice no change. </span></div></div></blockquote><div><br></div></span><div>### Let's say the A/B circuits run all the way from a simulation of your spinal cord sensory areas, such as the substantia gelatinosa, all the way to the frontal lobe cortical areas involved in attaching an affective valence to sensory stimuli (cingulate cortex, DLPF and others). We simulate the neural processes of you being slowly burned alive, separately in circuit A and in circuit B, and route the identical output to the rest of the brain. Obviously, the other parts of the brain, involved in e.g. producing screams and generating a memory of pain, will not scream twice as loud, or remember twice the pain. Yet, a process sufficient to produce the experience of pain ran twice. Are you sure you know how much pain was actually experienced by the system as a whole (A+B+ the rest of you)? Please note that the observable results of the experiment (loud screaming) would be the same no matter whether A/B are digital or analog.</div><div><br></div><div>As I mentioned in the initial post, I do not know. My intuitions are overtaxed by the problem.</div></div></div></div></blockquote><div><br></div><div>If I tried either a 20% reduction in the painful stimulus I would be in slightly less pain and scream slightly less, while if circuit A were switched off I would feel I was in just as much pain and scream just the same. So if I had a choice, I would choose the 20% reduction. If you told me that I was deluded about my pain, and I was actually better off switching circuit A, I would probably use some bad words telling you what you could do with your advice.</div></div></div></div></blockquote><div><br></div><div>### Obviously, other people's pain doesn't hurt much. I know that. The discussion is not just about the pain you remember but about the sum total of pain being experienced in the system under consideration.</div><div><br></div><div>Rafal </div></div>

</div></blockquote><br></span></div></div><div>But in your example *I* am the system under consideration. And as far as I'm concerned, the duplicated neural circuits make no difference to the pain I experience. Who rather than I, the experiencer, would be in a better position to judge this?</div></div></blockquote><div><br></div><div>### Who is this "I" you are talking about? Remember, circuits A and B are a huge chunk of neural wetware, they contain all you need to feel pain (as far as we can tell from fMRI scans and other sources). If you remove both, what is left is a mind that can talk, see, hear and do math, among other things, but cannot feel or remember pain. The human mind is largely modular and from the existence of congenital analgesia we know you can have a more or less normal human who cannot feel physical pain.</div><div><br></div><div>So again, a human mind with duplicated and independently running pain circuitry - he clearly will not say he feels double the pain, because the rest of him does not know that there are two pain circuits running, and the output of the circuits is not summed. But the question for us who know he has two pain circuits - does he as a whole feel twice the pain and just not know it?</div><div><br></div><div>Does it hurt if you don't remember?</div></div></div></div></blockquote><div><br></div><div>Something enjoyed the 11th bite of the breakfast Rafal ate 89 days ago. Was that something you, if you don't remember it?</div><div><br></div><div>I don't think memories have any bearing on the validity of past experiences. If the block time view of time is correct, then humanity (if we survive) 500 years from now could look back at this moment, and conclude that because we are all dead in their time frame, our experiences don't matter. But their opinion is of no relevance to the we who inhabit and experience this moment.</div><div><br></div><div>Jason</div><div> </div></div><br></div></div>
