I am here to speak on freedom of speech. It is a great topic, and I am going to make my speech as free as possible. But you know that this cannot be done, for when anyone announces that he is going to speak his mind freely, everyone is frightened. This shows that there is no such thing as true freedom of speech. No one can afford to let his neighbors know what he is thinking about them. Society can exist only on the basis that there is some amount of polished lying and that no one says exactly what he thinks.
