George Orwell: Politics, Rhetoric, And the Public Intellectual‪.‬

For the rest, talking to one's fellow man in a language that he cannot understand may be the bad habit of some revolutionaries, but it is not at all a revolutionary instrument: it is on the contrary, an ancient repressive artifice, known to all churches, the typical vice of our political class, the foundation of all colonial empires. (Primo Levi, "On Obscure Writing")
