In principle, membership of these three groups is not hereditary. The child of Inner Party parents is in theory not born into the Inner Party. Admission to either branch of the Party is by examination, taken at the age of sixteen. Nor is there any racial discrimination, or any marked domination of one province by another. Jews, Negroes, South Americans of pure Indian blood are to be found in the highest ranks of the Party, and the administrators of any area are always drawn from the inhabitants of that area. In no part of Oceania do the inhabitants have the feeling that they are a colonial population ruled from a distant capital. Oceania has no capital, and its titular head is a person whose whereabouts nobody knows. Except that English is its chief lingua franca and Newspeak its official language, it is not centralised in any way. Its rulers are not held together by blood-ties but by adherence to a common doctrine. It is true that our society is stratified, and very rigidly stratified, on what at first sight appear to be hereditary lines. There is far less to-and-fro movement between the different groups than happened under capitalism or even in the pre-industrial ages. Between the two branches of the Party there is a certain amount of interchange, but only so much as will ensure that weaklings are excluded from the Inner Party and that ambitious members of the Outer Party are made harmless by allowing them to rise. Proletarians, in practice, are not allowed to graduate into the Party. The most gifted among them, who might possibly become nuclei of discontent, are simply marked down by the Thought Police and eliminated. But this state of affairs is not necessarily permanent, nor is it a matter of principle. The Party is not a class in the old sense of the word. It does not aim at transmitting power to its own children, as such; and if there were no other way of keeping the ablest people at the top, it would be perfectly prepared to recruit an entire new generation from the ranks of the proletariat. In the crucial years, the fact that the Party was not a hereditary body did a great deal to neutralise opposition. The older kind of Socialist, who had been trained to fight against something called ‘class privilege’, assumed that what is not hereditary cannot be permanent. He did not see that the continuity of an oligarchy need not be physical, nor did he pause to reflect that hereditary aristocracies have always been shortlived, whereas adoptive organisations such as the Catholic Church have sometimes lasted for hundreds or thousands of years. The essence of oligarchical rule is not father-to-son inheritance, but the persistence of a certain world-view and a certain way of life, imposed by the dead upon the living. A ruling group is a ruling group so long as it can nominate its successors. The Party is not concerned with perpetuating its blood but with perpetuating itself. Who wields power is not important, provided that the hierarchical structure remains always the same.
