In Lire le Capital,Louis Althusser suggests a philosophical reading of Marx's works.In his view,the western economists'and historian interpretation of Marx's works is a kind of “sinful” reading,debasing Marx's object and concept in the epistemology system of philosophy.He considers that Das Capital raised a question to the objects of classical Political Economics,and discovered the objective laws of Economics based on the crossing of their Discourses and Objects,and summarized the“Nonlinear”Development Pattern and scientific practice methods in Economic History.The essence of his reading lies in applying the analytical methods of Philosophy of Science to Political Economy and reading of Marx's works,but this approach does not have a reasonable theoretical basis.
