David Crystal (whose work on Original Pronunciation (OP) for Shakespearean productions I love) writes in his *The Cambridge Encyclopedia of Language*,
“This work is founded on the belief that the systematic analysis and discussion of #language is an essential step towards any world in which mutual respect and tolerance is a reality. ‘They don't speak like us; therefore, they aren't like us; therefore they don't like us’. This is the kind of logic that this book seeks to deny.”
