In this lecture from Yale instructor Paul North's chapter by chapter study of Marx's Capital, Volume 1, the course turns to the general formula of capital and the constant movement Marx associates with it. North examines how capital, once set into circulation, continually seeks to expand itself, laying groundwork for the concepts of absolute surplus value and valorization that structure the following chapters. The session marks a shift in the course from analyzing exchange and money toward analyzing production itself, previewing the extended discussion of the working day that follows in later classes. North continues his close, sequential reading of the 1872 text throughout.
