Me: How do you know you're not a moron? Alex: How do you know I'm a moron? Me: What makes you intelligent then? Alex: What makes me intelligent is that I'm intelligent. Me: See, you started off with the wrong foot. That's a logical fallacy called "circular reasoning," or "begging the question." Alex: I don't beg for anything. Me: Well, you are begging the question. Alex: What question? Me: What makes you intelligent. Alex: I'm just intelligent. Me: It's fine to think that, but what makes you intelligent? Alex: The fact that I'm intelligent. Me: Whatever.
