Speech, truth and liberty: Bentham to John Stuart Mill

Bentham’s Utilitarianism transforms earlier free speech doctrine in the service of the pursuit of truth and the control of government, preserving the distinction between statements of opinion and of fact and awarding the latter a lesser degree of protection.
