It seems like we know many facts about ourselves and the world around us, even if there vastly many others we know that we don’t know. But how do we know if what we believe to be true is really knowledge? Can our beliefs be both justified and true, yet still not count as genuine knowledge? If so, then how much confidence should we really have in our beliefs? Is there a way to strike a balance between paralyzing skepticism, on the one hand, and dogmatic conviction, on the other?
