Because the 1844 manuscripts show Marx's thought at the time of its early genesis, their publication, in English not until 1959,[2] 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 relatively ignored until recently, because his early works were considered more "philosophical" and by some as not "scientific" enough, that is, "economic" as in Das Kapital. However, Marxist humanists regard this book as one of the most important texts by Marx and crucial for understanding his entire thought, and Marxians also refer to it.
