20. The purpose of doing history: to create knowledge of the past or to inform where we are headed in the future?

Greg and Mike think about what the practice of history is for — whether or not it should have a purpose or destination, how it opens up or forecloses certain possibilities, and what historical ‘objectivity’ really consists of.

19. What are revolutions, and when are they necessary?

Greg and Mike talk (political, social, economic) revolution: what it is, when it’s necessary, how it’s represented, and what history has to teach us. Then, they turn to the present—the revolutions, or lack thereof, that we’re facing, and the challenges that incipient revolutionaries face in current conditions.
