本文简要叙述了海德格尔前后期思想的转变,着重阐述了后期海德格尔通过对“思”、“在”、“人”的规定,试图建立“天人合一”的新型关系的生态思想。笔者认为海德格尔提出的“人的本质就是人的存在”以及在自然面前尽可能地保持无言和沉默具有较多的合理性,并结合当前“全球问题”与“人类困境”对此作了适当的论证。 This paper briefly narrates the transformation of Heidegger’s thoughts before and after the period, emphasizing that Heidegger attempts to establish “harmony between man and nature through the stipulation of” thinking “,” being “and” person “ ”The new relationship between the ecological thinking. The author thinks that Heidegger proposed that “the essence of human beings is the existence of human being” and that there is more rationality in keeping silence and silence as far as possible in front of nature. Combining the current “global problems” with “human beings Dilemma ”made an appropriate argument.
