That they all mean the same thing by the word? Perhaps I say well if the fMRI scans match, then they must experience the same thing, but for me to make such an assumption I must assume some kind of philosophy of mind (do the fMRIs show a functional behavioral match?, do they show a biochemical match?, do they show a neural activity match?, etc.)</div><div dir="auto"><br></div><div dir="auto">You will say, we can, with a neural ponytail, merge two minds, and then shortcircuit the problem of other minds and other's qualia. But I would not be so sure. Does the visual cortex of a colorblind person even have the right circuitry to apprehended colors of a normally sighted person? In experiments with monkeys it took several weeks for their neurons to rewire themselves to be able to discriminate the new colors they were enabled to see via gene editing their retinas.</div><div dir="auto"><br></div><div dir="auto">So the idea that we could simply connect two brains, and have them immediately know how the other feels, seems uncertain to work in practice. If you merged two brains, one who hates the taste of chocolate and one who loves the taste of chocolate, what do the merged brains experience when they taste chocolate? It seems to me they would experience only one or the other, or some third thing neither experienced before. In either case, one brain doesn't learn what it was like for the other brain. So it seems the ponytail mind merger is not a panacea for solving the problem of understanding the qualia of others.</div><div dir="auto"><br></div><div dir="auto">Jason </div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, Jul 23, 2025, 6:15 PM Brent Allsop <<a href="mailto:brent.allsop@gmail.com">brent.allsop@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr"><br><div>In a conversation with ChatGPT about qualia, I said:</div><div><br></div><div><br></div><div>"<span style="font-family:Aptos,sans-serif;font-size:11pt">Something in the brain must be behaving
