Mention George Orwell's name, and most people think of Animal Farm(1945) or 1984 (1949). Fewer will recall his 1946 essay, "Politics and the English Language."
That's a shame, because that essay is an insightful analysis of how words' meaning can be manipulated to advance political causes.
On the surface, Orwell's essay was about how the English language has been debased, and how language corruption cripples our ability to comprehend what writers mean. An implication is that as words' meaning becomes obtuse, ideological causes can be advanced.
