Politics in a nutshell:
Peter has a banana. He says that eating it would leave him feeling “pretty good”.
Paul (who does not have a banana) says that eating a banana would make him feel “on top of the world”.
Peter says being dispossessed of the banana would leave him feeling “a bit gutted”.
Paul says if he were to receive a banana he’d be “over the moon”.
If we subtract “a bit gutted” from “over the moon”, we are left with “chuffed to bits”; and if we subtract “pretty good” from “on top of the world”, we are left with “tip top”. As “chuffed to bits” ranks higher than “pretty good”, and “tip top” ranks higher than “a bit gutted”, not only are we justified in taking Peter’s banana and giving it to Paul, we are morally obligated to do so.
