Assassination is the extreme form of censorship.

Don't be afraid to go in your library and read every book, as long as that document does not offend our own ideas of decency. That should be the only censorship.

Censorship, in my opinion, is a stupid and shallow way of approaching the solution to any problem... because in censorship always lurks the very great danger of working to the disadvantage of the American nation.

If in other lands the press and books and literature of all kinds are censored, we must redouble our efforts here to keep them free.

All censorships exist to prevent anyone from challenging current conceptions and existing institutions.

But we know that freedom cannot be served by the devices of the tyrant. As it is an ancient truth that freedom cannot be legislated into existence, so it is no less obvious that freedom cannot be censored into existence. And any who act as if freedoms defenses are to be found in suppression and suspicion and fear confess a doctrine that is alien to America.
