Socrates: And now, let me give an illustration to show how far our nature is enlightened or unenlightened:--Behold! a human being in a darkened den, who has a slack jaw towards only source of light in the den; this is where he has gravitated since his childhood, and though his legs and neck are not chained or restrained any way, yet he scarcely turns round his head. In front of him are images from faroff, projected onto a flickering screen. And others whom he cannot see, from behind their walls, control the images like marionette players manipulating puppets. And there are many people in such dens, some isolated one way, some another.
Glaucon: I see.
Socrates: And do you see, I said, the flickering screen showing men, and all sorts of vessels, and statues and collectible animals made of wood and stone and various materials, and all sorts of commercial products which appear on the screen? Some of them are talking, and there is rarely silence.
Glaucon: You have shown me a strange image, and they are strange prisoners.
Socrates: Much like us. And they see only their own images, or the images of one another, as they appear on the screen opposite them?
Glaucon: True, he said; how could they see anything but the images if they never chose to look anywhere else?
Socrates: And they would know nothing about a product they buy, except for what brand it is?
Socrates: And if they were able to converse with one another, wouldn't they think that they were discussing what mattered?
Glaucon: Very true.
Socrates: And suppose further that the screen had sounds which came from its side, wouldn't they imagine that they were simply hearing what people said?
Glaucon: No question.
Socrates: To them, the truth would be literally nothing but those shadowy things we call the images.
Glaucon: That is certain.
Socrates: And now look again, and see what naturally happens next: the prisoners are released and are shown the truth. At first, when any of them is liberated and required to suddenly stand up and turn his neck around, and walk and look towards the light, he will suffer sharp pains; the glare will distress him, and he will be unable to see the realities of which in his former state he had seen the images; and then imagine someone saying to him, that what he saw before was an illusion, but that now, when he is approaching nearer to being and his eye is turned towards more real existence, he has a clearer vision, -what will be his reply? And you may further imagine that his instructor is asking him to things, not as they are captured on the screen, but in living color -will he not be perplexed? Won't he imagine that the version which he used to see on the screen are better and more real than the objects which are shown to him in real life?
Glaucon: Far better.
Socrates: And if he is compelled to look straight at the light, will he not have a pain in his eyes which will make him turn away to take and take in the objects of vision which he can see, and which he will conceive to be in reality clearer than the things which are now being shown to him?
Glaucon: True, he now will.
Socrates: And suppose once more, that he is reluctantly dragged up a steep and rugged ascent, and hindered in his self-seeking until he's forced to think about someone besides himself, is he not likely to be pained and irritated? He will find that he cannot simply live life as he sees fit, and he will not have even the illusion of finding comfort by living for himself.
Glaucon: Not all in a moment, he said.
Socrates: He will require time and practice to grow accustomed to the sight of the upper world. And first he will see the billboards best, next the product lines he has seen advertised, and then things which are not commodities; then he will talk with adults and children, and will he know greater joy in having services done to him, or will he prefer to do something for someone else?
Socrates: Last of he will be able to search for the One who is greatest, reflected in each person on earth, but he will seek him for himself, and not in another; and he will live to contemplate him.
Socrates: He will then proceed to argue that this is he who gives the season and the years, and is the guardian of all that is in the visible world, and is absolutely the cause of all things which he and his fellows have been accustomed to behold?
Glaucon: Clearly, he said, his mind would be on God and his reasoning towards those things that come from him.
Socrates: And when he remembered his old habitation, and the wisdom of the den and his fellow-prisoners, do you not suppose that he would felicitate himself on the change, and pity them?
Glaucon: Certainly, he would.
Socrates: And if they were in the habit of conferring honours among themselves on those who were quickest to observe what was happening in the world of brands and what new features were marketed, and which followed after, and which were together; and who were therefore best able to draw conclusions as to the future, do you think that he would care for such honours and glories, or envy the possessors of them? Would he not say with Homer, "Better to be the poor servant of a poor master" than to reign as king of this Hell, and to endure anything, rather than think as they do and live after their manner?
Glaucon: Yes, he said, I think that he would rather suffer anything than entertain these false notions and live in this miserable manner.
Socrates: Imagine once more, I said, such an one coming suddenly out of the sun to be replaced in his old situation; would he not be certain to have his eyes full of darkness, and seem simply not to get it?
Glaucon: To be sure.
Socrates: And in conversations, and he had to compete in one-upsmanship of knowing the coolest brands with the prisoners who had never moved out of the den, while his sight was still weak, and before his eyes had become steady (and the time which would be needed to acquire this new habit of sight might be very considerable) would he not be ridiculous? Men would say of him that up he went with his eyes and down he came without them; and that it was better not even to think of ascending; and if any one tried to loose another and lead him up to the light, let them only catch the offender, and they would give him an extremely heavy cross to bear.
Glaucon: No question. Then is the saying, "In the land of the blind, the one eyed man is king," in fact false?
Socrates: In the land of the blind, the one-eyed man is crucified. Dear Glaucon, you may now add this entire allegory to the discussion around a matter; the den arranged around a flickering screen is deeply connected to the world of living to serve your pleasures, and you will not misapprehend me if you interpret the journey upwards to be the spiritual transformation which alike may happen in the monk keeping vigil or the mother caring for children, the ascent of the soul into the world of spiritual realities according to my poor belief, which, at your desire, I have expressed whether rightly or wrongly God knows. But, whether true or false, my opinion is that in the world of knowledge the Source of goodness appears last of all, and is seen only with an effort; and, when seen, is also inferred to be the universal author of all things beautiful and right, parent of light and of the lord of light in this visible world, and the immediate source of reason and truth in the intellectual; and that this is the power upon which he who would act rationally, either in public or private life must have his eye fixed.
Glaucon: I agree, he said, as far as I am able to understand you.
