The text for this essay comes from Sir Lewis Namier. “One has to steep oneself in the political life of a period,” so the decree reads, “before one can safely speak, or be sure of understanding, its language.” This article is an attempt to supply, not a complete grammar of Augustan politics, but a minor lexicographical entry. Historians sometimes talk as though the most urgent need were for an advanced glossary. The assumption behind this essay is that a more elementary gradus is required. The two key words under review, “party” and “faction,” have always occupied neighbouring berths in the British synonymy. Unfortunately, in the eighteenth-century vocabulary of politics, they became overlapping concepts. Or rather — this is the trouble — they sometimes merged, partially or completely; sometimes they did not; and sometimes they were even employed as antonymous terms. Examples of all these contrary applications are found in the work of Swift and Bolingbroke. As with other lexicographical enquiries, then, usage and abusage must be considered, as well as the simple dictionary definition of these terms.IEdmund Burke is still, in some quarters, valued more highly as a prophet than as a political thinker. His forecasts of the likely course of the Revolution have brought him a reputation for the occult among those who hold his moral views in little esteem, even though he may be regarded, most unfairly, as a sorcerer's apprentice who was engulfed by his own charmed vision.
