… on Crap, Castration, and Two Creations, concerning inter alia the biblical authors’ lack of hesitance in using… organic… imagery to get a point across.
I wrote on something similar once in treating of Swearing and Vulgarity (they are not the same thing).
What’s interesting about vulgarity is that a word that (in English, at any rate) emerges from the lower class is considered dirty. In post-Norman Conquest England, the Anglish speakers were the lower orders while the French conquerors used a more Latinate tongue. Consequently you wind up with lots of synonyms that mean exactly the same thing, but the words of the conquered are “crude” or “dirty” while the words of the conquerers are considered refined. A Norman noblewoman mentruated, expectorated, and perspired while her serving maid bled, spat, and sweated. The conquerers copulated, defecated, flatulated, and urinated while the conquered (pardon my English) fucked, shitted, farted, and pissed. The meanings of the words are identical, but the words originating in the languages of the conquered were designated as “filthy”. It’s interesting how the English class system still exerts this dead hand of oppression on our use of the language, long after the distinction between Norman and Anglo-Saxon disappeared and long after the English class system ceased to have anything like the impact on Americans that it did on Britons.
I suspect that every language has certain “taboo” words. Blasphemy (whether against God or human social norms) tells us what a society values above all. In an age that revered God, there were certain things you Could Not Say because they insulted the Holy One. Today, blasphemers continue to pay backward homage to God by always blaspheming the God of Abraham and never blaspheming Quetzlcoatl or Thor.
That said, we still have blasphemy and it still tells us what is sacrosanct to us. Revulsion at rape jokes, or use of the word “nigger” (by somebody outside the black community), revulsion at words like “kike” or “wetback” or various other racial slurs and so forth make perfectly clear what is valued by what is taboo to speak.
