The people in F451 are like the men in the cave in Plato's Myth of the Cave. Both of these poeple are not enlightened and don't see the world as it really is. The main population in F451 are told not to think about things, they are only supposed to absorb and consume things. To think about things might make them realize something more than themselves annd make them unhappy. It is easier to stay secure and ignorant than find true knowledge.
In Plato's "Myth of the Cave", when the men leave the cave and are enlightened, it is difficult for them to take it all in at first. They need to look at the shadows after looking at the sun so their eyes can adjust. When they go back to the cave and tell others of what they have seen, the others don't want to hear it. They want to stay in the security of their shadows. The population of F451 wants to stay secure too, they don't to be enlightened, they want to be happy.
So what do you think? Agree or disagree? Want to add? (Btw Brittany, can I edit this later? I think I said "thing" too much.)
