Plato's Allegory Of The Cave
Here is Plato’s “Allegory Of The Cave”
So, there are some men who have spent their whole life inside a cave, chained to a wall. The wall they are chained to faces the wall of the cave.
These men have never left the cave and have never spoken to anybody else.
Behind them is a fire, which lights the cave that is in front of them.
The people who chained them to the wall use shadow puppets to entertain the men who are chained to the wall.
To the men chained to the wall the shadows produced by the shadow puppets is their entire world. They are their reality. Their reality is the reality of the shadow puppets.
But: What would happen if they were released from the cave?
They would soon see that their whole reality was a sham reality that bared no resemblance to the real world, outside the cave.
They would be bewildered and shocked. They would be disoriented and confused.
Humankind inside The Simulation are in the same predicament as the men in Plato’s allegorical cave. We are unaware of the world outside and we have no means of knowing anything at all about it at all.
