Every other man spoke a language entirely his own, which he had figured out by private thinking: he had his own ideas and peculiar ways. If you wanted to talk about a glass of water, you had to start back with God creating the heavens and earth; Abraham, Moses and Jesus; Rome; the Middle Ages; gunpowder; the Revolution; back to Newton; up to Einstein; then war and Lenin and Hitler. After reviewing this and getting it all straight again you could proceed to talk about a glass of water. ‘I’m fainting, please get me a little water.’ You were lucky even then to make yourself understood.
~ Saul Bellow, Seize the Day
Montaigne somewhere reminds us that “we can misuse only things which are good.” Language is misused for the same reason most things are: because the pleasures of bad grammar beat the pleasures of good. I wonder if the abuses of language don’t generally tend toward solipsism, the temptation to isolate oneself or to push others away. You may end up incomprehensible to anyone but yourself, of course, but masturbation has always been a private pastime.
