Social Scientist Capital These essays had attracted wide attention at the time they were published, and were used extensively in Marx study circles all over the country. What distinguished them was the fact that they were authored by an outstanding professional economist, familiar with frontier research not only in Marxist economics but in bourgeois economics as well, and with a rare mastery over mathematical and statistical techniques. They were therefore written with a panache and sureness of touch that one often finds lacking in standard textbooks. Since the 1970s, when these essays were written, there have been dramatic changes in the world capitalist system which are of far- reaching economic, political and ideological significance. However, they are being presented in this book exactly as they were when first published. The central reason for this is that they did not deal with capitalism as it existed at the time they were written, except for passing references. Instead, they are an exposition of Marx's ideas as presented in Volume I of , intended for lay readers and students with an inclination to analytical thinking as well as interest in progressive thought. The book does, however, include an introduction by the author explaining the changed context.
