What happens when impeccable reasoning is applied to nonsense premises
Carroll was a logician by day, and his Wonderland is full of arguments that are structurally flawless and entirely deranged. The Mad Hatter proves that I see what I eat and I eat what I see are not the same thing; Humpty Dumpty demonstrates that a word can mean whatever the speaker chooses, provided the speaker is willing to pay it; the Queen of Hearts operates on the principle that sentence comes before verdict because it saves time. The joke, gently made, is that valid reasoning is not the same as sound reasoning — and that polite society does a great deal of the former while pretending it is doing the latter.
