Economic and Philosophic Manuscripts of 1844 (also referred to as The Paris Manuscripts) are a series of notes written between April and August 1844 by Karl Marx. Not published by Marx during his lifetime, they were first released in 1927 by researchers in the Soviet Union. The notebooks are an early expression of Marx's analysis of economics and critique of G.W.F. Hegel. The notes cover a wide range of topics including private property, communism, and money. They are best known for their early expression of Marx's argument that the conditions of modern industrial societies result in the estrangement (or alienation) of wage-workers from their own life. Because the 1844 manuscripts show Marx's thought at the time of its early genesis, their publication has profoundly affected recent scholarship on Marx and Marxism, particularly regarding the relation of Marxism to earlier work in German Idealism. The young Marx had been ignored until recently, because his early works were considered more "philosophical" and not enough "scientific," that is, "economic" as in Das Kapital. However, Marxist humanists regard this book as one of the most important books of Marx and crucial for understanding his thought, and Marxians also refer to it.
