The point is that we are all capable of believing things which we know to be untrue, and then, when we are finally proved wrong, impudently twisting the facts so as to show that we were right. Intellectually, it is possible to carry on this process for an indefinite time: the only check on it is that sooner or later a false belief bumps up against solid reality, usually on a battlefield.
George OrwellExcept for the small revolutionary groups which exist in all countries, the whole world was determined upon preventing revolution in Spain. In particular the Communist Party, with Soviet Russia behind it, had thrown its whole weight against the revolution. It was the Communist thesis that revolution at this stage would be fatal and that what was to be aimed at in Spain was not workers' control, but bourgeois democracy. It hardly needs pointing out why 'liberal' capitalist opinion took the same line.
