answer:I’m not quite sure what you’re asking here. If you’re asking “Is there some kind of machine that will let me feel exactly what another person is feeling?” then your answer is no. If you’re talking about the more abstract “Bob says he is sad, how can I feel that sadness?” then I think the answer to that is a bit more complex. Assuming that’s the question, I’d say no. You can be told exactly why Bob is sad, he can describe his feelings, but unless you somehow are Bob, and have experienced everything he has in his life, you can’t fully grasp why Bob is sad, and how that actually feels. If you’re asking a more physical question of “Bob says his hand is hot, Is there a way for me to experience that feeling in my hand?” then I’d answer I don’t know. I’m sure there’s been research put into artificial nerve stimulation. (if not research, I know it’s been thought about in SciFi genres.) I don’t know if they’ve been able to say something like “this one nerve makes your brain think your hand is hot, so if we stimulate it in this way, your hand will feel hot, even though it’s cold” My guess would be that the technology to do this is a few years off. Maybe you’re asking if there’s a way to translate Bob’s nervous system reactions into your own, and I’d assume that that’s a couple decades off.
