[D]o not expect Americans to believe that freedom of speech is some disguised puppetry of the powerful. It is, to the contrary, an indispensable ingredient in the recipe for preventing tyrannies, be they of the left or right, be they in the name of the Fatherland, the Volk, or the workers. To say otherwise is merely to perform what Michael Polanyi called a "moral inversion”-an intellectual juggling act in which we are asked, in Orwellian terms, to regard freedom as slavery, discrimination as nondiscrimination, and truth as power.
