Edward Skidelsky in Prospect Magazine writes about words that think for us:
No words are more typical of our moral culture than “inappropriate” and “unacceptable.” They seem bland, gentle even, yet they carry the full force of official power. When you hear them, you feel that you are being tied up with little pieces of soft string.
Inappropriate and unacceptable began their modern careers in the 1980s as part of the jargon of political correctness. They have more or less replaced a number of older, more exact terms: coarse, tactless, vulgar, lewd. They encompass most of what would formerly have been called “improper” or “indecent.” An affair between a teacher and a pupil that was once improper is now inappropriate; a once indecent joke is now unacceptable.
This linguistic shift is revealing. Improper and indecent express moral judgements, whereas inappropriate and unacceptable suggest breaches of some purely social or professional convention. Such “non-judgemental” forms of speech are tailored to a society wary of explicit moral language. As liberal pluralists, we seek only adherence to rules of the game, not agreement on fundamentals. What was once an offence against decency must be recast as something akin to a faux pas.
