Cool blast through three-and-a-bit millennia of talk of Christ’s bowels and fucking shit. She distinguishes between ‘obscenities’ and ‘oaths’ (the first takes profane subjects, the second sacred) and then between the proper and the vain oath (e.g. “Bejasus! Godammit! Hell’s teeth!”). Adding the generalisation that ‘we swear about what we care about’, she can use known changes in the expressive power of swearwords to cleverly trace the movement of taboos across cultures and over time. (Very broadly: power went from Shit’s precedence to Holy and now back and with more political terms.) Rome’s nasty little sexuality is seen to be the model of a lot of our crap associations; in the Middle Ages vain oaths were criminal while scholars and physicians used ‘cunt’ in textbooks without heat. In our time, racial slurs (very young as slurs – only around WWII for their worst malevolence) have taken the biscuit from sex, excrement and God - which you can see as encouraging (if that means we now care about the targets of racial language) - or depressing (if that means we now care more about Race, dividing lines for their own sake). Mohr is full of fact without being trivial; she lets graffiti, court records, and primary quotation damn the damnable – e.g. DH Lawrence’s holy cock-mysticism, the spume of Twitter bigots.
