Before them is a wall and behind them a fire burns. Others in the cave pass before the fire holding objects which cast shadows on the wall.

Later, a prisoner is released and taken to the outside world. At first he recoils from the bright light, but he gradually adjusts until he sees the outside world just as if he had lived his whole life above ground instead of in a cave.

Plato’s purpose in telling this story through Socrates is not to entertain with a tale of fancy, but to describe in metaphorical form the reasoning behind one of his chief philosophies:

the senses cannot be trusted. The connection is clear; the prisoners in the cave are as ignorant of the truth as Glaucon was, if he relied solely on what he saw. The prisoners, having lived their whole life in the cave, would look upon the shadows they saw and recognize them as reality. In

the same way, Glaucon and others like him believed what they saw and experienced was in fact the reality of the Universe. Conversely, Plato believed that the truth of the Universe was hidden and that the way to discover it was not through observation of the surrounding world but through

logic and reasoning.

You must experience something and not only judge something from the way it looks. You must first live in someone’s shoes before you are able to feel what they feel and understand how they live. Never judge something by its cover and from the outside. Live and breathe, then speak.

Hope that helps you. 🙂

RE:
What is the moral of the Allegory and the Cave?
and if you know, how?

The meaning is that most people prefer to remain in chains and to see only shadows of the truth. Only the few — and the wise — are willing to free themselves from the shackles and look the truth in the face, even if it is blinding at first.
