A free society does not ban or burn books. It does not attempt to control the language and thought of its citizens.

As we see censorship, it is a stupid giant traffic policeman answering ‘Yes’ to ‘Am I my brother’s copper?’ He guards a one-way street and his semaphore has four signs, all marked ‘STOP.’

Franklin P. Adams, Nods and Becks, 1944

The problem of freedom in America is that of maintaining a competition of ideas, and you do not achieve  that by silencing one brand of idea.

Max Lerner, Actions and Passion, 1949
