edit: didn’t see rule 1, but anyway I expect answers to be open ended. Just give your thoughts
We are fundamentally ignorant, and are tricked by our brains into thinking we fundamentally know.
Have a look at the book, “The Self Illusion” by Bruce Hood and “The Mind is Flat” by Nick Chater.
Very simplistic question demanding very simplistic answer on a subject with a history of 2000+ years of epistemology that should have been in a philosophy community instead of asklemmy.
One could get good answers from a philosophy community, I agree. My original motivation was getting answers from people in general further than philosophy-subscribed people, almost like trying to start a discussion with friends, you know? One can always do own research or ask an AI otherwise.
