Pat was feeling swampy (gross!) so Ben freshens him up with a zesty thought experiment called The Swamp Man. Conceived by American philosopher/rip-off artist Donald Davidson, The Swamp Man is a bananas thought experiment meant to illustrate the theory of meaning called semantic externalism. How do you mean the words you say if you’re a Swamp Man who has never experienced anything and never encountered any of the objects of this world? Find out on this very special screaming match of I Learned Nothing.
