The mass political movements of the 20th century were vehicles for myths inherited from religion, and it is no accident that religion is reviving now… - John N. Gray

Not everything in religion is precious or deserving of reverence. There is an inheritance of anthropocentrism, the ugly fantasy that the Earth exists to serve humans, which most secular humanists share. There is the claim of religious authorities, also made by atheist regimes, to decide how people can express their sexuality, control their fertility and end their lives, which should be rejected categorically. Nobody should be allowed to curtail freedom in these ways, and no religion has the right to break the peace.

Contrary to generations of western progressives, it was not Russian backwardness or mistakes in applying Marxian theory that produced the society that Lyons observed. Similar regimes came into being wherever the communist project was attempted. Lenin’s Russia, Mao’s China, Ceausescu’s Romania and many more were variants of a single dictatorial model. From being a movement aiming for universal freedom, communism turned into a system of universal despotism. That is the logic of utopia. If 1984 is such a powerful myth, one reason is that it captures this truth. Yet there is a flaw in Orwell’s story, which emerges in his picture of the all-powerful interrogator. The dystopia of perpetual power is a fantasy, and so is O’Brien. Soviet torturers were sweating functionaries living in constant fear. Like their victims, they knew that they were resources that would be used up in the service of power. There was no inner-party elite safe from the contingencies of history.

In Leopardi’s view, the universal claims of Christianity were a licence for universal savagery. Because it is directed to all of humanity, the Christian religion is usually praised, even by its critics, as an advance on Judaism. Leopardi – like Freud a hundred years later – did not share this view. The crimes of medieval Christendom were worse than those of antiquity, he believed, precisely because they could be defended as applying universal principles: the villainy introduced into the world by Christianity was ‘entirely new and more terrible … more horrible and more barbarous than that of antiquity’. Modern rationalism renews the central error of Christianity – the claim to have revealed the good life for all of humankind. Leopardi described the secular creeds that emerged in modern times as expressions of ‘half-philosophy’, a type of thinking with many of the defects of religion. What Leopardi called ‘the barbarism of reason’ – the project of remaking the world on a more rational model – was the militant evangelism of Christianity in a more dangerous form. Events have confirmed Leopardi’s diagnosis. As Christianity has waned, the intolerance it bequeathed to the world has only grown more destructive. From imperialism through communism and incessant wars launched to promote democracy and human rights, the most barbarous forms of violence have been promoted as means to a higher civilization.
