近代伊始的西方哲学有以主客二分式的“自我”为原则的传统，这一传统对“自我”的认识势所必然会导致自我认识循环的困境。马克思对人的自由及其社会本质的规定，为走出自我性的圈子和自我认识循环的困境提供了最为有益的启示。 The western philosophy of the beginning of modern times had the tradition of “subject” and “self” as the principle. The understanding of “self” by this tradition inevitably leads to the dilemma of self-awareness cycle. Marx’s stipulation of human freedom and its social essence provides the most beneficial enlightenment for going out of self-circle and self-understanding cycle.
