So if I say that a joke is funny, they can provide the quantum rules describing why?
And also why you may not think it's funny?
This theory may well be neato spiffy, but it's not universal.
One question which Wittgenstein concerned himself with is the rules of language. He postulated a language which consisted of two speakers, one of whom was a mason and the other of whom was a mason's assistant. The language had two words - "brick" and "mortar". Each time the mason uttered "brick" it meant that the assistant would hand him a brick and each time he said "mortar" the assistant would provide him with mortar. Wittgenstein postulated that even in so impoverished a system humor would be possible - the one type of joke in this language would be if the mason said "mortar" and the assistant handed him a "brick" instead.
