Their friendship was at an end, it seemed to him. The evil time when he had lived on Ravelston had spoiled everything. Charity kills friendship. - George Orwell

Don’t you see that the whole aim of Newspeak is to narrow the range of thought? In the end we shall make thoughtcrime literally impossible, because there will be no words in which to express it.

Doublethink means the power of holding two contradictory beliefs in one's mind simultaneously, and accepting both of them.

The idea that an advanced civilization need not rest on slavery is a relatively new idea, for instance; it is a good deal younger than the Christian religion. But even if Chesterton's dictum were true, it would only be true in the sense that a statue is contained in every block of stone. Ideas may not change, but emphasis shifts constantly. It could be claimed, for example, that the most important part of Marx's theory is contained in the saying: ‘Where your treasure is, there will your heart be also.’ But before Marx developed it, what force had that saying had? Who had paid any attention to it? Who had inferred from it — what it certainly implies — that laws, religions and moral codes are all a superstructure built over existing property relations? It was Christ, according to the Gospel, who uttered the text, but it was Marx who brought it to life. And ever since he did so the motives of politicians, priests, judges, moralists and millionaires have been under the deepest suspicion — which, of course, is why they hate him so much.'
