It’s wonderful stuff, swearing. It stiffens the sinews and summons up the blood, and not just metaphorically. Obscenities actually do act on us physiologically. Swearing increases electrical conductance across the skin, pushes the heart rate higher and measurably increases resistance to pain.
Obscenities are also linguistically interesting in themselves: the more currency they have, the more their emotional colouring and the associations they trigger overwhelms what they actually mean. ”Fucking”, these days, only rarely means “having sex”. And they become marvellously plastic, grammatically.
Swearing doesn’t just mean what we now understand by “dirty words”. It is entwined, in social and linguistic history, with the other sort of swearing: vows and oaths. Consider for a moment the origins of almost any word we have for bad language – “profanity”, “curses”, “oaths” and “swearing” itself .
Melissa Mohr’s title, then, is more than just an attention-grabber: the history of swearing is one of a movement back and forth between the holy and the shit. At different times in the history of the west, the primary taboo has been to do either with God, or with the functions of the human body. (The latter, though, does subdivide in a meaningful way between the sexual and the excremental. Really, this book should have been called “Holy Fucking Shit”.)
