Does the prisoner in the cave in Plato's allegory in The Republic have free will?
The prisoners in the cave are just ordinary human beings; whether or not they have free will is another question in philosophy. The point behind the "allegory of the cave" is the prisoners believe the projection screen in front of them is real, in much the same way a motion picture appears real. One day a prisoner escapes and discovers the world is much larger and more unusual that he had thought. He returns to the cave to share this knowledge with the other prisoners. They just laugh at him and think he has gone mad.
