Humpty Dumpty on the meaning of words

"When I use a word, "said Humpty Dumpty in rather a 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."
