In popular culture, people like to say “It’s just semantics!” which is a kind of put-down: it implies that their correspondent is quibbling over minor details of meaning in a jesuitical way. But communication is all about meaning: even if you and I use different words to mean the same thing, we understand one another, but if we use the same word to mean different things, great confusion results. In this study, therefore, we will wear the phrase “It’s just semantics!” as a badge of honor, because semantics leads to discourse which (we hope) leads to civilization.

Just semantics. That’s all there is.
