Although none of Mill’s other essays—save, perhaps, “The Church, and Its Reform” (1835)—proved so controversial, each expands upon points made in passing in the Essay on Government. Jurisprudence deals extensively with rights—what they are, by whom they are defined, and how they are best protected. In a similar vein and in a way that anticipates (and arguably influenced) the younger Mill’s On Liberty (1859) Liberty of the Press defends the right of free speech and discussion against arguments in favor of restriction and censorship. Free government requires the free communication of ideas and opinions, and good government requires an informed and critical citizenry. For both, a free press is an indispensable instrument.
