With the emergence of democracies in Europe and the New World at the beginning of the nineteenth century, political philosophers began to re-evaluate the relationship between freedom and equality. Tocqueville, in particular, saw the creation of new forms of social power that presented threats to human liberty.

The concept of "general will" is considered Rousseau's most important contribution to political science. It is presented as the answer to the gravest problems of civilization, namely, the problems of inequality, amour-propre, and general discontent. The social contract is the foundation of the general will and the answer to the problem of natural freedom, because nature itself provides no guidelines for determining who should rule. The lecture ends with Rousseau's legacy and the influence he exercised on later nineteenth-century writers and philosophers.

The discussion on the origins of inequality in the Second Discourse continues. This lecture focuses on amour-propre, a faculty or a disposition that is related to a range of psychological characteristics such as pride, vanity, and conceit. The Social Contract is subsequently discussed with an emphasis on the concept of freedom and how one's desire to preserve one's freedom is often in conflict with that of others to protect and defend their own. General will becomes Rousseau's solution to the problem of securing individual liberty.

This lecture is an introduction to the life and works of Rousseau, as well as the historical and political events in France after the death of Louis XIV. Writing in a variety of genres and disciplines, Rousseau helped bring to fruition the political and intellectual movement known as the Enlightenment. Among his most important works is the Second Discourse (Discourse on Inequality), in which Rousseau traces the origins of inequality and addresses the effects of time and history on humans.

In this lecture, two important issues are addressed in the context of Locke's Second Treatise. First, there is discussion on the role of the executive vis-a-vis the legislative branch of government in Locke's theory of the constitutional state. Second, Locke's political theories are related to the American regime and contemporary American political philosophy. The lecture concludes with John Rawls' book, A Theory of Justice, and how his general theory relates to Locke's political ideas.

In the opening chapters of his Second Treatise, Locke "rewrites" the account of human beginnings that had belonged exclusively to Scripture. He tells the story of how humans, finding themselves in a condition of nature with no adjudicating authority, enjoy property acquired through their labor. The lecture goes on to discuss the idea of natural law, the issue of government by consent, and what may be considered Locke's most significant contribution to political philosophy: the Doctrine of Consent.

John Locke had such a profound influence on Thomas Jefferson that he may be deemed an honorary founding father of the United States. He advocated the natural equality of human beings, their natural rights to life, liberty, and property, and defined legitimate government in terms that Jefferson would later use in the Declaration of Independence. Locke's life and works are discussed, and the lecture shows how he transformed ideas previously formulated by Machiavelli and Hobbes into a more liberal constitutional theory of the state.

The concept of sovereignty is discussed in Hobbesian terms. For Hobbes, "the sovereign" is an office rather than a person, and can be characterized by what we have come to associate with executive power and executive authority. Hobbes' theories of laws are also addressed and the distinction he makes between "just laws" and "good laws." The lecture ends with a discussion of Hobbes' ideas in the context of the modern state.

Hobbes' most famous metaphor, that of "the state of nature," is explained. It can be understood as the condition of human life in the absence of authority or anyone to impose rules, laws, and order. The concept of the individual is also discussed on Hobbesian terms, according to which the fundamental characteristics of the human beings are the capacity to exercise will and the ability to choose. Hobbes, as a moralist, concludes that the laws of nature, or "precepts of reason," forbid us from doing anything destructive in life.

This is an introduction to the political views of Thomas Hobbes, which are often deemed paradoxical. On the one hand, Hobbes is a stern defender of political absolutism. The Hobbesian doctrine of sovereignty dictates complete monopoly of power within a given territory and over all institutions of civilian or ecclesiastical authority. On the other hand, Hobbes insists on the fundamental equality of human beings.
