Then this goes back to my point of “if you can’t prove your own sentience to yourself, maybe that’s worth digging into.” The very baseline of philosophy is “I think therefore I am.” It’s the one thing Descartes thought one can know with certainty. If you question even that about yourself, it might imply an abnormal psychology or that you’re overthinking things to a point of pedantry that even a 17th century philosopher would say is “a bit much.”
