Terry Eagleton in Sidecar [h/t: Leonard Benardo]:
A well-known member of the British left once discovered to his surprise that several of his socialist friends, including myself, had all attended the same school. We weren’t, however, public schoolboys in flight from our privileged backgrounds; nor was the school the kind of place where you call the teachers Nick and Maggie and are encouraged to have sex on the floor of the assembly hall. It was a Roman Catholic grammar school in Manchester, run by an obscure order of clerics, and like most Catholic schools in Britain its pupils were almost all descendants of Irish working-class immigrants.
There have been a number of prominent Catholics on the British left, most of them what the church would call ‘lapsed’. To be lapsed is less a matter of ceasing to be a Catholic than a particular way of being one – a fairly honorific way, in fact, which includes such luminaries as Graham Greene and Seamus Heaney. The result is that nobody can ever leave the Catholic church; instead, they are simply shuttled from one category to another, rather as a retired Brigadier is still a Brigadier. The political philosopher Raymond Geuss confesses in his latest book, Not Thinking like a Liberal, that his religious upbringing failed to make him even a bad Catholic; yet bad Catholics are what the lapsed really are, often productively so. They can be heretics in the truth, to use John Milton’s phrase. Geuss may not go along with the church on such minor matters as the existence of God, but he insists that none of his fundamental attitudes have changes since his schooldays, which the clerics who taught him would no doubt be delighted to hear. As a staunch anti-liberal, he remains a bad Catholic to the end.
