“so much knowledge against it”? We live in a n overwhelming ocean of information, what seems obvious to many people may be completely unheard of in other areas, we’re not all getting our information from the same sources. Or some people have become indoctrinated by other groups and have become basically inoculated against “wokeism”. Plato’s allegory of the cave is just as relevant today as it was in his time (if not more so). There are people spending their whole lives looking at shadow puppets dancing on the wall, thinking that that’s reality. Who knows, maybe it’s us, but the point is, even though we’re awash in information, ignorance is alive and well.
