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. Every concept that can ever be needed will be expressed by exactly one word, with its meaning rigidly defined and all its subsidiary meanings rubbed out and forgotten.”
The problem is the same for all three super-states. It is absolutely necessary to their structure that there should be no contact with foreigners, except, to a limited extent, with war prisoners and colored slaves. Even the official ally of the moment is always regarded with the darkest suspicion. War prisoners apart, the average citizen of Oceania never sets eyes on a citizen of either Eurasia or Eastasia, and he is forbidden the knowledge of foreign languages. If he were allowed contact with foreigners he would discover that they are creatures similar to him and that most of what he has been told about them is lies. The sealed world in which he lives would be broken, and the fear, hatred, and self-righteousness on which his morale depends might evaporate.
