Logiklektion i Underlandet

Det finns en del att lära om vikten av klarhet i tanken i Alice’s Adventures in Wonderland:

”Then you should say what you mean,” the March Hare went on.
”I do,” Alice hastily replied; ”at least at least I mean what I say that’s the same thing, you know.”
”Not the same thing a bit!” said the Hatter. ”Why, you might just as well say that ‘I see what I eat’ is the same thing as ‘I eat what I see’!”
“You might just as well say,” added the March Hare, “that ‘I like what I get’ is the same thing as ‘I get what I like’!”

Bertrand Russell kommenterar boken:

It raises metaphysical points, very interesting logical points, that are good for the older ponderer, but for the young produce only confusion.

(Tack till David N. för tipset.)

Uppdatering: Peter Santesson-Wilson ger en utmärkt illustration av poängen ovan då han skriver:

Alla dyslektiker stavar illa, men om alla som stavar illa befordras till dyslektiker saknar ordet mening.
