In the history of Chinese and European philosophy, metaphysics has played an outstanding role: it is a theoretical framework which provides the basis for a philosophical understanding of the world and the self. A theory of the self is well integrated in a metaphysical understanding of the totality of nature as a dynamic process of continuous changes.Metaphysics has, however, suffered a loss of importance in current debates, especially in ethics. As a result, we observe the emergence of such philosophical views as moral skepticism and even nihilism. The consequence of this tendency has been the renunciation of a claim to understanding and to providing a solid ground for ethics.
