Words, and their meanings, matter. Words are not vessels that can be filled with whatever meaning one wants. Kung Fu-tzu, who lived 500 years before Christ, said that before a debate begins, the participants should participate in “rectification of terms.” What he meant was that the participants in the debate should agree on the definitions of the key words to be used. After rectification of terms, many points of dispute disappear. In the US today, we need a rectification of terms, especially in politics and media news. Opposing sides use the same words in disputation, but give them very different meanings.
