"In the brave old days, I used to know Ralph Miliband, father of David and Edward and one of Britain’s leading Marxist intellectuals. There was a European for you: part Polish, part Belgian, and part Jewish, arriving in England on forged papers as an illegal immigrant refugee from Hitler. His best-known book was Parliamentary Socialism, in which he analyzed Labor’s attempt to transform society through the ballot box. His conclusion was that a party too wedded to pragmatism and compromise would in the end sacrifice its principles, but in doing so it would also cease to work as an electoral machine. Perhaps I’ll take this book down from the dusty old shelf on which I have preserved it."
