Twenty four hundred years ago, Plato, one of history’s most famous thinkers, said life is like being chained up in a cave forced to watch shadows flitting across a stone wall. Beyond sounding quite morbid, what exactly did he mean? Alex Gendler unravels Plato's Allegory of the Cave, found in Book VII of "The Republic."
