Today those who peer into the future want only relief from anxiety. Unable to face the prospect that the cycles of war will continue, they are desper… - John N. Gray

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.

If our universe is one of many, unlike others in containing observers like ourselves, there is no need to posit a designer. Most universes will be too chaotic to allow the emergence of life or mind. In that case, the fact that humans exist in this universe needs no special explanation

Human knowledge increases, while human irrationality stays the same. Scientific inquiry may be an embodiment of reason, but what such inquiry demonstrates is that humans are not rational animals. The fact that humanists refuse to accept the demonstration only confirms its truth.
