“The very efficacy of opinion manipulation rests on the fact that we do not know we are being manipulated. The most insidious forms of oppression are those that so insinuate themselves into our communication universe and the recesses of our minds that we do not even realize they are acting upon us. The most powerful ideologies are not those that prevail against all challengers but those that are never challenged because in their ubiquity they appear as nothing more than the unadorned truth.”
