The allegory of the cave PDF is a philosophical dialogue by Plato that presents the idea of the allegory of the cave. The allegory is a metaphor for our restricted understanding of actuality and the significance of looking for information and fact.
Within the allegory, a bunch of prisoners is chained in a cave, going through a wall. All they’ll see are shadows projected on the wall by objects passing behind them. The prisoners imagine that the shadows are actual, and so they know nothing of the surface world.
