Right to Protest Quotes
Marie Joseph Paul Yves Roch Gilbert du Motier
Samuel Langhorne Clemens, 1835-1910. Twain was referring to the social norms and customs which make us all edit our speech so that we do not hurt people unnecessarily or mislead someone. True freedom of speech of this kind would exist only if there were no social structure of morality. For almost all of us, the political freedom of speech is what we cherish. The right to say anything and to be edited only by ourselves and our own personal view of propriety is the political. See linked quote for his quotation about the social consequences of exercising freedom of speech.
This quotation was used ten years later by Virginia which, in convention, passed a resolution objecting to the Alien & Sedition Acts. The drafter of the original resolution was James Madison.
