who said i do not agree with what you say but i will defend to death your right to say it
Evelyn Beatrice Hall In The Friends of Voltaire, Hall wrote the phrase: "I disapprove of what you say, but I will defend to the death your right to say it"[4] (which is often misattributed to Voltaire himself) as an illustration of Voltaire's beliefs.[5][6][7] Hall's quotation is often cited to describe the principle of freedom of speech.
Right to silence Neither the reasons nor the history behind the right to silence are entirely clear. The Latin brocard nemo tenetur se ipsum accusare ('no man is bound to accuse himself') became a rallying cry for religious and political dissidents who were prosecuted in the Star Chamber and High Commission of 16th-century England. People coming before these tribunals were forced to make the ex officio oath by which they swore to truthfully answer the questions to be put before them without knowing what they were being accused of. This created what has been termed the cruel trilemma whereby these accused were forced to choose between committing the mortal sin of perjury (if they lied under oath to protect themselves), harsh punishment for contempt of court (if they refused to answer), or betraying their "natural" duty of self-preservation (if they told the truth to honour their oath).
