The Second Renaissance Part 1 & 2 
Zion Archive Computer: In the beginning, there was man. And for a time, it was good. But humanity's so-called civil societies soon fell victim to vanity and corruption. Then man made the machine in his own likeness. Thus did man become the architect of his own demise.
Kid: Somebody tell me. Why does it feel more real when I dream than when I am awake?, How can I know if my senses are lying?
Neo: There is some fiction in your truth, and some truth in your fiction. To know the truth, you must risk everything.
(written and directed by Yoshiaki Kawajiri)
Duo: Maybe you regret taking the red pill.
(directed by Koji Morimoto)
Manabu: You know, you're not supposed to go in there... but we don't really care about that.
(written and directed by Shinichiro Watanabe)
Trinity: There's a difference between a test and a choice. For what it's worth, I think you could've handled the truth.
(written and directed by Peter Chung)
- [Nonaka and Alexa talk of converting a intelligent machine to help them]
Alexa: Will it...? Do you think it will convert?
Nonaka: To convert is its choice to make.
Alexa: Do you think we ought to reprogram it?
Nonaka: No. We can't make slaves of them.
Alexa: Because that would be simpler.
Nonaka: We won't beat the machines by making them our slaves. Better to let them join us by choice.
Alexa: Make them believe the right choice is the one we want.
Nonaka: All right. Yes, machines are tools. They're made to be used. It's their nature.
Alexa: To be slaves.
Nonaka: That's why we show them a better world, why they convert.
Alexa: But that world we show them isn't real.
Nonaka: It doesn't matter.
Alexa: I'm afraid they'll figure out that we've made up the thing in our heads.
Nonaka: They can't tell the difference. To an artificial mind, all reality is virtual. How do they know that the real world isn't just another simulation? How do you?
Alexa: I know I' m not dreaming now because I know what its like being in a dream.
Nonaka: So dreaming lets you know that reality exists?
Alexa: No. Just that my mind exists. I don't know about the rest.
