is it a heavy proposition that you were in an accident, were operated on while unconscious, had hands transplanted, or had technically advanced lifelike robotic hands neurologically connected to the brain. Woke up with amnesia about the accident, fully recovered and see you have working hands? Or would that still be considered as having hands, they're just not your hands? 🙃
It would depend on the wording of the proposition. "I have hands" and "I see that I have hands" are different from saying "I have the same hands as when I was born." And of course, it can also be true that you think something and for it not to be knowledge.
