"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."

“Science is not distinguished from myth by science being literally true and myth only a type of poetic analogy. While their aims are different, both are composed of symbols we use to deal with a slippery world.”

“The belief in unity that has fuelled so many utopian dreams is an effort to reconcile the irreconcilable that ends in repression. Berlin suggests we renounce this venerable faith, and learn how to live with intractable conflict.”

“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.”

“Freud taught that for any human being kindness or cruelty, having a sense of justice or lacking it, depend on the accidents of childhood. We all know this to be true, but it goes against much of what we say we believe. We cannot give up the pretence that being good is something anyone can achieve. If we did, we would have to admit that, like beauty and intelligence, goodness is a gift of fortune. We would have to accept that, in the parts of our lives where we are most attached to it, freedom of the will is an illusion.”

“Action preserves a sense of self-identity that reflection dispels. When we are at work in the world we have a seeming solidity. Action gives us consolation for our inexistence. It is not the idle dreamer who escapes from reality. It is practical men and women, who turn to a life of action as a refuge from insignificance.”

“Gamblers wager for the sake of playing. Among those who fish for pleasure, the best fisherman is not the one who catches the most fish but the one who enjoys fishing the most. The point of playing is that the play has no point.”
