George Orwell (Eric Arthur Blair), 1903-1950
was an English essayist, novelist, and satirist
The great enemy of clear language is insincerity. When there is a gap between one's real and one's declared aims, one turns as it were instinctively to long words and exhausted idioms, like a cuttlefish spurting out ink.
( “Politics and the English Language”, 1946 )
