I also attempted to solve the “other peoples mind” problem by introducing empathetical experiences where you know you mutually experienced something. I got this idea when I was reading Lemune’s q&a with Googles AI, where the AI was describing the experience with data processing. For a second I believe I also experienced a touch of it though it might be an illusion. But gradually I learnt to trust my gut feeling. Many spiritual teachings seemed to resonate with my experiences but yes it seems not many commenters on this thread even consider empathic experiences to exist.
