23 - Paradise XXX, XXXI, XXXII, XXXIII
Professor Mazzotta lectures on the final cantos of Paradiso (30-33). The pilgrim's journey through the physical world comes to an end with his ascent into the Empyrean, a heaven of pure light beyond time and space. Beatrice welcomes Dante into the Heavenly Jerusalem, where the elect are assembled in a celestial rose. By describing the Empyrean as both a garden and a city, Dante recalls the poles of his own pilgrimage while dissolving the classical divide between urbs and rus, between civic li
20 - Paradise XVIII, XIX, XXI, XXII
In this lecture, Professor Mazzotta examines Paradiso 18-19 and 21-22. In Paradiso 18, Dante enters the heaven of Jupiter, where the souls of righteous rulers assume the form of an eagle, the emblem of the Roman Empire. The Eagle's outcry against the wickedness of Christian kings leads Dante to probe the boundaries of divine justice by looking beyond the confines of Christian Europe. By contrasting the political with the moral boundaries that distinguish one culture from another, Dante opens
17 - Paradise IV, VI, X
This lecture deals with Paradiso 4, 6 and 10. At the beginning of Paradiso 4, the pilgrim raises two questions to which the remainder of the canto is devoted. The first concerns Piccarda (Paradiso 3) who was constrained to break her religious vows. The second concerns the arrangement of the souls within the stars. The common thread that emerges from Beatrice’s reply is the relationship between intellect and will. Just as Piccarda’s fate reveals the limitations of the will, the represent
13 - Purgatory XIX, XXI, XXII
This lecture deals primarily with Purgatorio 19, 21 and 22. The ambiguity of the imagination discussed in the preceding lecture as the selfsame path to intellectual discovery and disengagement is explored in expressly poetic terms. While the pilgrim’s dream of the siren in Purgatorio 19 warns of the death-dealing power of aesthetics, the encounter between Statius and Virgil in the cantos that follow points to its life-giving potential by casting poetry as a means of conversion.
08 - Inferno XXVI, XXVII, XXVIII
Professor Mazzotta begins this lecture by recapitulating the ambivalent nature of Ulysses’ sin and its relevance to Dante’s poetic project. Inferno 27 is then read in conjunction with the preceding canto. The antithetical relationship between Dante’s false counselors, Ulysses and Guido da Montefeltro, anchors an overarching discussion of the relationship between rhetoric and politics. The latter half of the lecture is devoted to Inferno 28, where Dante’s preeminent sower of discord, B
05 - Inferno IX, X, XI
In this lecture, Professor Mazzotta discusses Inferno 9-11. An impasse at the entrance to the City of Dis marks Virgil’s first failure in his role as guide (Inferno 9). The invocation of Medusa by the harpies that descend while they wait for divine aid elicits Dante’s first address to the reader. The question of literary mediation, posed in the previous lecture in the context of Inferno 5, is explored further, and the distinction Dante draws between the “allegory of poets” and the “
2.019 Design of Ocean Systems (MIT)

01 - Introduction
Professor Mazzotta introduces students to the general scheme and scope of the Divine Comedy and to the life of its author. Various genres to which the poem belongs (romance, epic, vision) are indicated, and special attention is given to its place within the encyclopedic tradition. The poem is then situated historically through an overview of Dante's early poetic and political careers and the circumstances that led to his exile. Professor Mazzotta concludes by discussing the central role Dante
26 - Race and Reunion: the Civil War in American Memory
Having dealt with the role of violence and the Supreme Court in bringing about the end of Reconstruction in his last lecture, Professor Blight now turns to the role of national electoral politics, focusing in particular on the off-year Congressional election of 1874 and the Presidential election of 1876. 1874 saw the return of the Democrats to majority status in the Senate and the House of Representatives, as voters sick of corruption and hurt by the Panic of 1873 fled the Republicans in droves.
The Joy of Economics: Making Sense out of Life
My goal is to provide an accessible book that reflects this theme of choice and conveys a sense of the breadth and power of basic economic analysis. It assumes no prior knowledge of economics and can be read and appreciated by anyone. While some parts of the book cover conventional material, others do not. I've ignored many traditional topics and substituted ones that apply economics in unusual and often provocative ways. The chapters are not meant to be definitive, they are meant to raise q

AlgTop2: Homeomorphism and the group structure on a circle
This is the first video of the second lecture in this beginner's course on Algebraic Topology. We give the basic definition of homeomorphism between two topological spaces, and explain why the line and circle are not homeomorphic.
Then we introduce the group structure on a circle, or in fact a general conic, in a novel way, following Lemmermeyer and as explained by S. Shirali.
This gives a gentle intro to the definition of a group. It also uses Pascal's theorem in an interesting way, so we gi

17.57J Soviet Politics and Society, 1917-1991 (MIT)
At its greatest extent the former Soviet Union encompassed a geographical area that covered one-sixth of the Earth's landmass. It spanned 11 time zones and contained over 100 distinct nationalities, 22 of which numbered over one million in population. In the 74 years from the October Revolution in 1917 to the fall of Communism in 1991, the Union of Soviet Socialist Republics, its leaders and its people, had to face a number of difficult challenges: the overthrow of the Tsarist autocracy, the est
17.508 The Rise and Fall of Democracy/ Regime Change (MIT)
Coups, civil wars, revolutions, and peaceful transitions are the "real stuff" of political science. They show us why politics matters, and they highlight the consequences of political choices in times of institutional crisis. This course will help you understand why democracies emerge and why they die, from ancient times to the recent wave of democratization in Southern Europe, Eastern Europe, and the developing world.
Few things are more dramatic than the collapse of a political system, whether
