I provide a qualitative study of the unpublished portions of the Middle Stone Age (MSA) lithic assemblage from the Porc-Epic cave site in Ethiopia, presently conserved at the National Museum of Ethiopia (NME), in Addis Ababa.

Previous investigation of all the lithic material collected during the 1933 excavations resulted in an in-depth technological study, revealing its important technical variability, and integrated this material into a regional and continental context. The focus here are the 1975-76 excavations at Porc-Epic Cave, which have provided a collection of several tens of thousands of stone tools, forming the majority of the total lithic material of the cave. This collection, never before studied, published, or inventoried, is stored at the NME in Addis Ababa. It is remarkable for its quantitative importance and its relevance to Ethiopian heritage, as well as for its scientific interest concerning the behaviour of modern humans more than 70,000 years ago.

industrial capital remained subject to the restrictions of use-value production. Through the theories of profit and rent, therefore, industrial capital had to subdue the technical variability and contingency inherent in the production of use-values. Only after this problem was settled in its teleological
