There is, of course, an interaction between freedom of conscience and belief, on the one hand, and freedom of speech, on the other. Usually when one speaks, one is expressing what one believes. Although belief and speech are, in one sense, two sides of the same coin, there is an important distinction between them. When the government seeks to prevent someone from speaking his or her mind, that is what we traditionally call censorship. Censorship is generally a dreadful thing, but coercing belief and conscience is yet more pernicious and evil, because it invades the inner being of an individual's life. Sometimes tyrannical power seeks to force individuals under its sway to speak or utter things that the speaker does not believe. In our moral tradition, that is a frightful assault upon the innermost sanctum of human privacy and dignity. In our legal tradition, it is a worse violation of the First Amendment to force someone to say that which he does not believe (which we might describe as an affirmative form of censorship) than to prevent him from saying that which he does believe (which we might describe as a negative form of censorship).
