There was a fella once running for a train, and he’s carrying a pair of gloves, this man. He drops a glove on the platform, but he doesn’t notice. And then later on, inside the train, he’s sitting by the window and he realizes that he’s just got this one glove left. But the train’s already started pulling out of the station, right? So what does he do? He opens the window and he drops the other glove onto the platform. That way, whoever finds the first glove can just have the pair.
Let me tell you what’s gonna happen Officer Grimly. I’m going to roll my window up, then I’m going to drive away, and you’re gonna go home to your daughter, and every few years, you’re gonna look at her face and know that you’re alive because you chose not to go down a certain road on a certain night, that you chose to walk into the light instead of into the darkness. Do you understand me?
Lorne Malvo, Fargo S01E01 The Crocodile’s Dilemma
The crocodile paradox, also known as crocodile sophism, is a paradox in logic in the same family of paradoxes as the liar paradox. The premise states that a crocodile, who has stolen a child, promises the father/mother that their child will be returned if and only if they correctly predict what the crocodile will do next. The crocodile dilemma serves to expose some of the logical problems presented by metaknowledge. Ancient Greek sources were the first to discuss the crocodile dilemma.
