This lecture, part of Yale instructor Paul North's chapter by chapter study of Marx's Capital, Volume 1, focuses on Chapter 23 and Marx's claim that capital accumulation follows a discernible, lawful process. North examines what that law consists of and how Marx uses it to explain recurring patterns in capitalist economies, building directly on the course's prior sessions covering expanded reproduction. The lecture continues the course's close, sequential engagement with the 1872 text, situating this chapter as a turning point before the course moves into Marx's account of so-called original accumulation in the following class.
