In this six-lecture course recorded in July of 2010 at the Objectivist summer conference in Las Vegas, Nevada, Leonard Peikoff discusses the final parts of his then book-in-progress The DIM Hypothesis, published in 2012.

Here is a description of the book from the back cover of the softcover edition:

“In this far-reaching study, Peikoff identifies the three methods of integrating data, as when connecting diverse experiments by a scientific theory, or separate laws into a Constitution, or single events into a story. The first method, in which data is integrated through rational means, he calls Integration. The second, which employs nonrational means, he calls Misintegration. The third is Disintegration—which is nihilism, the desire to tear things apart.

“In The DIM Hypothesis, Peikoff demonstrates the power of these three methods in shaping the West, by using the categories to examine the culturally representative fields of literature, physics, education, and politics. Extrapolating from the historical pattern he identifies, Peikoff concludes by explaining why the lights of the West are going out—and predicts the most likely future for the United States.”

Note: Since the lectures that compose this course predate the book’s completion, the book supersedes the course. If and when there are disagreements between the two, listeners should assume that the published book represents Peikoff’s viewpoint.
