In the Eden of the East opening, there are a lot of quotes from different sources. The only one I know the origin of is "The abuse of greatness is when it disjoins remorse from power," which is from Julius Caesar by William Shakespeare. I don't know what the other quotes that show up on the screen are from or are in reference to. Can someone tell me?
This blogpost has a transcript of all of the text from the opening. Not all of them are famous quotes.
"I saw you in Heaven and heard of your glory You saved our world from the fallen angels I saw Messiah standing Standing before me with no words Nothing but "Hope" When we lost dread, a Demon was laughing But now you are showing us wonder Giving your love With awe, down on my knees again I've got to know you're the one The only one reveals the world"
This is repeated multiple times throughout the OP and seems to be part of the song 東のエデン挿入歌「Reveal The World」
"The abuse of greatness is when it disjoins remorse from power."
As you've noted, it's Brutus from Julius Caesar, by William Shakespeare.

These seem to be options (partially obscured) of the phone.
"Let me walk with you when I'm lost in the wild I know you always lead me to another Eden Let me bless your name, O Lord, O Lord Your words will never fade away Since we believe you're the light on earth Reveals the world"
Also from the "Reveal the world" song lyrics.
The rest seems to be proper names and instances from the show itself, like "noblesse oblige", and "Juiz", and "Selecao system 12 persons selected in Japan". So the only real quote I guess is from the Julius Caesar play.
