Neo: Why am I here?
The Architect: Your life is the sum of a remainder of an unbalanced equation inherent to the programming of the matrix. You are the eventuality of an anomaly, which despite my sincerest efforts I have been unable to eliminate from what is otherwise a harmony of mathematical precision. While it remains a burden assiduously avoided, it is not unexpected, and thus not beyond a measure of control. Which has led you, inexorably, here.
Neo: You haven't answered my question.
The Architect: Quite right. Interesting. That was quicker than the others.
Niobe: Morpheus, I can't help thinking... What if all this - the prophecy, everything - is bullshit?
Morpheus: Then tomorrow we may all be dead, but how would that be different from any other day? This is a war, and we are soldiers. Death can come for us at any time, in any place. Now consider the alternative. What if I am right? What if the prophecy is true? What if tomorrow the war could be over. Isn't that worth fighting for? Isn't that worth dying for?
Neo: I suppose the most obvious question is, how can I trust you?
The Oracle: Bingo. It is a pickle. No doubt about it. The bad news is there's no way if you can really know whether I'm here to help you or not, so it's really up to you. You just have to make up your own damned mind to either accept what I'm going to tell you, or reject it.
The Architect: Hello, Neo.
Neo: Who are you?
The Architect: I am the Architect. I created the Matrix. I've been waiting for you. You have many questions, and although the process has altered your consciousness, you remain irrevocably human. Ergo, some of my answers you will understand, and some of them you will not. Concordantly, while your first question may be the most pertinent, you may or may not realize it is also the most irrelevant.
Councillor Harmann: There is so much in this world that I do not understand. See that machine? It has something to do with recycling our water supply. I have absolutely no idea how it works. But I do understand the reason for it to work. I have absolutely no idea how you are able to do some of the things you do, but I believe there's a reason for that as well. I only hope we understand that reason before it's too late.
Agent Smith: Surprised to see me?
Agent Smith: Then you're aware of it.
Neo: Of what?
Agent Smith: Our connection. I don't fully understand how it happened, perhaps some part of you imprinted on to me, something overwritten or copied, it is at this point irrelevant. What matters is whatever happened, happened for a reason.
Neo: And what reason is that?
Agent Smith: I killed you Mr. Anderson, I watched you die, with a certain satisfaction I might add. And then something happened. Something that I knew was impossible but it happened anyway. You destroyed me Mr. Anderson. Afterward, I knew the rules, I understood what I was supposed to do, but I didn't. I couldn't. I was compelled to stay, compelled to disobey. And now here I stand because of you Mr. Anderson, because of you, I am no longer an Agent of this system, because of you I've changed, I'm unplugged, a new man so to speak. Like you, apparently, free.
Agent Smith: Thank you. But, as you well know appearances can be decieving, which brings me back to the reason why we're here. We are not here because we're free, we're here because we are not free. There is no escaping reason, no denying purpose, because as we both know, without purpose, we would not exist.
Multiple Smiths: It is purpose that created us. Purpose that connects us. Purpose that pulls us, that guides us, that drive us. It is purpose that defines, purpose that binds us.
Agent Smith: We are here because of you Mr. Anderson. We're here to take from you what you tried to take from us. Purpose.
