In the contemporary philosophical movements that emphasize the philosophy of anti-hegelianism, it is interesting to note that the philosophy of Hegel has been interpreted in the contrary way. On the one hand, by highlighting the concept of the Absolute Subjectivity the philosophy of Hegel is understood as the philosophy of identity or as the prototype of the closed philosophical system. But on the other hand, with the concept of the "Absolute Negativity," one argues that the philosophy of Hegel essentially coincides with the contemporary philosophy that pursues the philosophy of difference. Facing these contrary interpretations, we first want to investigate the structure of Hegel's philosophy, which makes possible these contrary understandings. In order to clarify these two opposed interpretations, we will examine the concept of Being and Nothing which constitute the essential aspects of Hegel's philosophy. According to Hegel, there are two ways, namely, metaphysical approach and anthropological approach, to clarify the concept of Being and Nothing. Hence in this paper, by clarifying these two approaches, we seek to elucidate the double-aspects in the philosophy of Hegel. For Hegel, while Being refers to the concept of identity, nothing signifies the concept of difference. However, the concept of pure Being that relates to itself in terms of absolute identity is nothing other than pure Nothing. From the perspective of the indeterminateness, pure Being and Nothing are identical, and this unity of Being and Nothing is understood as 'Becoming'. So in the philosophy of Hegel, the concept of Being that is immediately given comprises the 'movement' and 'becoming.' This metaphysical understanding of Being and Nothing is rediscovered in the anthropological explanation of man. Man finds her/himself in nature, and he is defined as 'in itself.' But on the other hand man has a power to negate nature, so that he can become a 'for-in-itself' that is free by creating one's own self. In other words, man defined as a 'for-in-itself' is essentially constituted in negation and freedom. So in the philosophy of Hegel Being and Nothing, 'in-itself' and 'for-in-itself' and the natural being and freedom discloses the double aspects of the same state of affair. Here one can see that the philosophy of Hegel can be explained by the double aspect of Being and Nothing which leads to the contrary interpretation on his thoughts.
