The Allegory of the Cave by Plato
Presented by the Greek philosopher Plato, it consists of a dialogue between Plato’s brother in addition to his mentor, Socrates. The Allegory of the Cave presents a scenario with which a collective group has spent their entire existence chained in a cave only able to observe the shadows being cast by objects passing in front of a fire positioned behind them. To those living in the cave, the shadows are perceived as absolute reality, and if one was to break free from the cave and enter the world outside one would observe an environment that is very different from the reality they have known through their entire existence, with the light being painful to perceive, as one has spent their existence in the dark observing shadows. In essence, there exist higher realms of reality that one may not be aware of, and oftentimes individuals are quite accepting of a life in the cave, as that has been their only known existence.
