Economics research methods of economics that were affected by different philosophy were also self-contradicted. It was until Marxist philosophy, which explained human essence correctly, that economics research methods became matured and perfect. 2 Contradiction of economics research methods because of human essence complexity reflected that, research subject of economics is basis on human or on matter, the contradiction between abstraction and description, the contradiction between individualism and wholisms, the contradiction between views of static and movement. 3 Economics should be practical economics, whose research subject was the law of movement, which unified the practical economic la\v and human economic objective.
