Recent work by party scholars reveals a widening gap between the normative ideals we set out for political parties and the empirical evidence that reveals their deep and perhaps insurmountable shortcomings in realizing these ideals. This disjunction invites us to consider the perspective of David Hume, who offers a theory of the value and proper function of parties that is resilient to the pessimistic findings of recent empirical scholarship. I analyze Hume's writings to show that the psychological experience of party informs the opinions by which governments can be considered legitimate. Hume thus invites us to consider the essential role parties might play in securing legitimacy as that ideal is practiced or understood by citizens, independent of the ideal understandings of legitimacy currently being articulated by theorists. My analysis contributes to both recent party scholarship and to our understanding of the role of parties in Hume's theory of allegiance.

Machiavelli's influence on David Hume's political thought is a subject of growing scholarly attention. I analyze Hume's “Of Parties in General” to show that the introduction to this essay is a critical appropriation of Machiavelli'sDiscourses on Livy. I argue that Hume's appropriation of Machiavelli provides a meaningful frame to an essay in which Hume will consciously build upon one of Machiavelli's most controversial teachings, that good political founding is hampered by the effects of Christianity on political thinking. My analysis contributes to our understanding of Machiavelli's influence on Hume by showing Machiavelli's imprint much beyond where it is usually the subject of debate, in Hume's political science.
