She [Alice] went on "And how do you know that you're mad?" "To begin with," said the Cat, "a dog's not mad. You grant that?" "I suppose so," said Alice. "Well, then," the Cat went on, "you see, a dog growls when it's angry, and wags it's tail when it's pleased. Now I growl when I'm pleased, and wag my tail when I'm angry. Therefore I'm mad."
Lewis CarrollI maintain that any writer of a book is fully authorised in attaching any meaning he likes to a word or phrase he intends to use. If I find an author saying, at the beginning of his book, "Let it be understood that by the word 'black' I shall always mean 'white,' and by the word 'white' I shall always mean 'black,'" I meekly accept his ruling, however injudicious I think it.
