By the late nineteenth century the recurrence of this pattern had become obvious to many observers. There then rose schools of thinkers who interpreted history as a cyclical process and claimed to show that inequality was the unalterable law of human life. This doctrine, of course, had always had its adherents, but in the manner in which it was now put forward there was a significant change. In the past the need for a hierarchical form of society had been the doctrine specifically of the High. It had been preached by kings and aristocrats and by the priests, lawyers, and the like who were parasitical upon them, and it had generally been softened by promises of compensation in an imaginary world beyond the grave. The Middle, so long as it was struggling for power, had always made use of such terms as freedom, justice, and fraternity. Now, however, the concept of human brotherhood began to be assailed by people who were not yet in positions of command, but merely hoped to be so before long. In the past the Middle had made revolutions under the banner of equality, and then had established a fresh tyranny as soon as the old one was overthrown. The new Middle groups in effect proclaimed their tyranny beforehand. Socialism, a theory which appeared in the early nineteenth century and was the last link in a chain of thought stretching back to the slave rebellions of antiquity, was still deeply infected by the Utopianism of past ages. But in each variant of Socialism that appeared from about 1900 onwards the aim of establishing liberty and equality was more and more openly abandoned. The new movements which appeared in the middle years of the century, Ingsoc in Oceania, Neo-Bolshevism in Eurasia, Death-Worship, as it is commonly called, in Eastasia, had the conscious aim of perpetuating UNfreedom and INequality. These new movements, of course, grew out of the old ones and tended to keep their names and pay lip-service to their ideology. But the purpose of all of them was to arrest progress and freeze history at a chosen moment. The familiar pendulum swing was to happen once more, and then stop. As usual, the High were to be turned out by the Middle, who would then become the High; but this time, by conscious strategy, the High would be able to maintain their position permanently.
