'A bodily action is like a word; we mean things to each other no less by what we do than by what we say. In fact, when the speech of the mouth contradicts the speech of the body, the body's speech reveals the mouth's. To crush your windpipe with my thumbs is to say to you, "Now die," even if I tell you with my mouth, "Be alive." To join one flesh, is to say, "I give myself to you in all this act means," even if my mouth shapes the words, "This means nothing,"'
J Budziszewski, On the Meaning of Sex, p.27.
