Abstract: The thought of “Nature is the spiritual nourishment for human” was put forward by Karl Marx in view of the existence of “the ego-alienation of human being” in his era,which reflects his concern and consideration for the development of human beings.Therefore,we should focus on the development of the people's spiritual dimension on the basis of nature's germination and perfection for human beings to become themselves for a better understanding of the thought.Meanwhile,we should grasp it from three aspects:liberating nature to restore its character as the spiritual nourishment for human,liberating humans to restore the intrinsic spiritual relationship between human and nature,and constructing the beauty of nature “according to the aesthetic law”.By activating these thoughts,it will be helpful to solve the ecological and spiritual crisis at present intelligently,and highlight the value of time.

Key words: Karl Marx, nature, spiritual nourishment for human, value of the time
