Abstract: In todays world， human existence is a major theme of the times. As the earliest eco-Marxist who studies the way of existence from the perspective of Marxist theory， William Leiss has his unique logic thinking and research paradigm. He precisely predicts the turning of human alienation from production fields to consumption fields in the setting of high-intensity market and ascertains the historical trend of the way of existence from rational control to irrational cunning. William Leiss’s depiction of the eco-socialist blueprint seems to be an extremely romantic Utopia， but it is of greater importance that he opens up a research orientation from the perspective of ecological Marxism.

Key words: William Leiss, way of existence, critical reconstruction
