Iván Szelényi's Yale course Foundations of Modern Social Thought turns to John Locke as a liberal counterpoint to Hobbes. The lecture places Locke in his historical context before working through the First and Second Treatises, covering his claim that individuals are born free and equal, his account of why a common superior requires consent, and his theory of the origins and limits of private property. Szelényi contrasts Locke's assumption of resource abundance with Hobbes's scarcity, and distinguishes absolute monarchy from civil society before ending on Locke's separation of powers into executive, legislative, and federative branches. Chapter markers break the 45 minute talk into eight segments tracking this argument from state of nature to constitutional structure. Recorded in Fall 2009 as part of Yale's Open Courses, the lecture is lecture-hall plain: one instructor, a blackboard argument, and close textual reading of Locke's own words.
