Althusser "epistemological Break" Discussion

Louis Althusser, a French contemporary philosopher emerged in Western Marxism. Althusser to oppose the humanitarian of Marxism, to defend the scientific nature of Marxist theory and devoting himself to re-interpretation of Marx's theory of activity. He takes Marx's "German ideology" as the boundary, the former Marxist ideology completely separates later, and with the two basic concepts of ideology and science to show this "fault." Althusser, this new interpretation of Marx, dressing Marx as a really "theoretical anti-humanist." Before 1845, Marx's thought showed great immaturity, making pre-and post ideas of Marx to show different characteristics. But, Althusser's "epistemological break" that separates pre-and post ideas of Marx into two pieces is metaphysical, one-sided, does not meet the true history of the development of Marxist thought process of development.
