For if leisure and security were enjoyed by all alike, the great mass of human beings who are normally stupefied by poverty would become literate and would learn to think for themselves; and when once they had done this, they would sooner or later realise that the privileged minority had no function, and they would sweep it away. In the long run, a hierarchical society was only possible on a basis of poverty and ignorance.
From where Winston stood it was just possible to read, picked out on its white face in elegant lettering, the three slogans of the Party: WAR IS PEACE FREEDOM IS SLAVERY IGNORANCE IS STRENGTH.
It was with the last revolution and the coming of INGSOC (Inglish/English Socialism) that the latest High learnt how to keep their position permanently - by cultivating ignorance among the other classes and by constantly surveying them through the Thought Police.
