This chapter addresses various interpretations of Marx’s plans, as well as what Marx managed to complete during his lifetime. This chapter explores how the different levels of completeness should be understood for an accurate reading of Capital as a whole. It reviews several debates that occurred both before and after the release of MEGA2 and suggests that the interpretations made prior to MEGA2 can now be reassessed with empirical evidence on Marx’s efforts, potentially challenging some of those earlier views. Furthermore, the chapter highlights the unfinished nature of Capital, showing how the new findings of MEGA2 enhance our understanding of its incomplete state. This chapter presents MEGA2 as both a tool for interpreting the result of Marx’s work and a guide for further research into his extensive and unfinished project.
