This chapter explores the particularity of Montesquieu’s political vision that includes a commitment to traditional social orders alongside a defence of liberty. It demonstrates how later theorists associated with the liberal tradition develop at least one of three features largely derived from Montesquieu’s work that we now associate with modern liberalism once combined with a commitment to social and political equality. These features are: institutional and constitutional organization to guarantee political accountability and the rule of law; social pluralism and representative government as a structure for the aggregation, education and voicing of broad social interests; and an ethos of moderation and avoidance of cruelty in social and political life. They characterize broad aspects of the liberal tradition at the level of institutional design, the structure of civil society and the broad social ethos needed to sustain it. The chapter concludes with reflections on perceived threats to liberalism today.
