Chapter Two examines the status of political science, or prudence, in the League years. It looks at ways in which some leading League intellectuals sought to reclaim the idea of the ‘politique’ for their own cause, aligning the League with ‘correct’ political reasoning that reconciled Catholic orthodoxy with French political identity, and condemning the ‘false’ political reasoning of the so-called Machiavellians who opposed the movement. Intellectually speaking this chapter demonstrates that we can, therefore, discuss the notion of the ‘politique Leaguer’, and identify the common ground of understanding that united lawyers in the Paris parlement.
