Dialectics constitutes the philosophical method in Marx's Das Capital.If we look from the perspective of the object of study,the dialectics of Das Capital are Parallax Dialectics:it is embodied in the parallax of currency and the parallax of surplus value.Parallax is the difference formed by observing different perspectives of the same object.This difference depends on both the subject and the object.Therefore,the dialectics of parallax are formed between the subject and the object,and then be-tween the"positive object"and"the real object".Parallax dialectics,by facing this parallax,grasps the reality behind parallax phenomenon,and criticizes the observation still in the stage of"visual deception"on the basis of parallax reality.This paper holds that Marx's investigation of currency and surplus value is the embodiment of parallax dialectics.Therefore,the philo-sophical methodology of Das Capital from the perspective of parallax will be helpful to deepen the study of Das Capital in Chi-na.
