" The official philosophies of the totalitarian regimes unanimously brand as nonsensical the idea that there exists a single objective truth valid for everybody. The criterion of "truth," they say, is not agreement with reality, but agreement with the spirit of a race or nation or class—that is, racial, national or utilitarian. Pushing to their limits the biological, pragmatist, activist theories of truth, the official philosophies of the totalitarian regimes deny the inherent value of thought. For them thought is not a light but a weapon: its function, they say, is not to discover reality as it is, but to change and transform it with the purpose of leading us towards what is not. Such being the case, myth is better than science and rhetoric that works on the passions preferable to proof that appeals to the intellect. "
