“It would be impossible for me, for instance, to debate the rights and wrongs of the Barcelona fighting with a Communist Party member, because no Communist—that is to say, no ‘good’ Communist—could admit that I have given a truthful account of the facts. If he followed his party ‘line’ dutifully he would have to declare that I am lying or, at best, that I am hopelessly misled and that anyone who glanced at the Daily Worker headlines a thousand miles from the scene of events knows more of what was happening in Barcelona than I do. In such circumstances there can be no argument; the necessary minimum of agreement cannot be reached.”
