Theodore Dalrymple on the purposes of lies in totalitarian societies:
In my study of communist societies, I came to the conclusion that the purpose of communist propaganda was not to persuade or convince, nor to inform, but to humiliate; and therefore, the less it corresponded to reality the better. When people are forced to remain silent when they are being told the most obvious lies, or even worse when they are forced to repeat the lies themselves, they lose once and for all their sense of probity. To assent to obvious lies is to co-operate with evil, and in some small way to become evil oneself. One's standing to resist anything is thus eroded, and even destroyed. A society of emasculated liars is easy to control.
We are at war with a depraved enemy, but we cannot be allowed to assert our moral superiority even to head-choppers, rapists, slavers and immolators. Thus the priority of Barack ("Hey, how 'bout those Crusades?") Obama has been to undermine our sense of probity, and make us not merely equivalent to but worse than our enemies. That was the purpose of this last week of Official Lies.
