Eleanor-Janet: I don't get this, man. Why wouldn't you want to know what our life was like? You're not even a little bit curious what it was like to hit this? I don't mean this this. Although, frankly, I would also hit this this.
Chidi-Janet: I don't want to see those memories because, philosophically speaking, they're none of my business. They happened to someone else. Let me explain. [summons a black board] Take a seat. Conceptions of the self. Let's start with John Locke, who believed that personal identity was based on having a continued consciousness. Essentially, memory. Memories are links in a chain that together form a single self. If I can't remember what happened because it happened to a Chidi from another timeline, it's not a unified me.
Jason-Janet: Just because you don't remember doing something doesn't mean you didn't do it. I have no idea how it happened, but there is definitely a tattoo on my butt that says "Jasom."
Chidi-Janet: That brings us to Derek Parfit.
Tahani-Janet: It does?
Chidi-Janet: Parfit said even if I have memories from an earlier time, that doesn't necessarily mean it was me. After all, if my brain was split in two and each half was put in a different person, which one is me? All I know is that other Chidi doesn't exist anymore, and this one does. So this must be the real Chidi.
Eleanor-Janet: And all I know is that you're just barfing Wikipedia all over everyone to avoid talking about your feelings.
Chidi-Janet: Let's talk about David Hume.
