"I don't know what you mean by 'glory'," Alice said.
Humpty Dumpty smiled contemptuously. "Of course you don't --

"But glory doesn't mean 'a nice knock-down argument'," Alice
objected.
"When I use a word," Humpty Dumpty said, in a rather scornful
tone, "it means just what I choose it to mean -- neither more nor less."
"The question is," said Alice, "whether you can make words mean
so many different things."
"The question is," said Humpty Dumpty, "which is to be master --
that's all."
