This is a polemical tract in defence of press freedoms, and free speech generally, on philosophical grounds.

Bentham’s statement of press freedom argues to permit political associations/assemblies in public and resistance to governmental authority as a check to abuse of power. Special mention of permitting criticism, including of state officials, and a discussion of how sedition and defamation of public officials should be addressed.

Mill argues for limited governmental intervention in silencing or compelling speech, emphasizes the value of contrary and minority opinions and presents a principle on which any governmental action in respect of speech should be based.

Bagehot argues for toleration by the state and under law of a diversity of opinions, and argues that discussions and exchange of opinions must be in pursuit of uncovering truths.

Originally intended as the preface to Animal Farm, discusses the motivations to self-censorship in literary endeavours.
