Abstract: Rejected by modern western philosophy,metaphysics was marked as a dying philosophy.However,it is eager to play an increasingly important role in influencing people’s spirit.The reason why metaphysics has been rebelled is that only in the field of transcendental ideas is it valid.Metaphysics has essential value,which shows pure spirit of freedom,criticism and transcendence.Thought is the nature of metaphysics,and the thinking mode which is in accordance with the nature of thinking is dialectics.In a material world which lacks thinking,a pure theoretic attitude and solid metaphysics are needed.

Key words: metaphysics, transcendental ideas, dialectics, pure theory attitude
