Karl Marx wrote "The Poverty of Philosophy" (1847) in response to the respected work "The Philosophy of Poverty" by Proudhon published that same year. "The Poverty of Philosophy" is a rebuttal to Proudhon's anarcho-socialist opining. It focuses, as much of Marx's writings do, on the philosophy of economy. Most ardently, Marx views Proudhon as wrongfully attempting to raise above the bourgeoisie, an act which dislocates him from Marx's revolutionary platform. The text fits neatly into the evolution of Marx's developing dialectical materialism and is seen as clearly demarcating scientific socialism from utopian socialism. A great treatise in itself, "The Poverty of Philosophy" also forms an interesting dialogue with Proudhon-one that eventually dismantled their friendship, simultaneously creating a schism between Anarchist and Socialist schools of thought. The work is seen as essential to the philosophical apotheosis found in Marx and Engel's revolutionary text "The Communist Manifesto."
