In her delightful book In the Land of Invented Languages, just out in paperback and written up in yesterday's Philadelphia Inquirer, one of my fellow Chicago-trained linguists, Arika Okrent, explores the world's myriad made-up languages and the eccentrics behind them.
"There is a lot of messiness and ambiguity in language... We need it. We need that wiggle room. But if you have an engineering mind, you'll see irritating things. Why do words have more than one meaning?...Why do we have irregular verbs? Why are pronouns in English so messed up?"
In the late 1940s, Austrian engineer Charles Bliss invented Blissymbolics, which he hoped could become a writing system for all languages, "logical writing for an illogical world." And James Cooke Brown [better known for the board game Careers] invented Loglan, a language that followed the rules of logic.
