Abstract: Starting from the famous opinion of Leo Strauss on Weber, and based on works in the tradition of general Phenomenological Sociology, this paper tries to analyze Max Weber's thoughts on Science and Homelessness. Through an analysis of Weber's texts, this paper finds that, contrary to Strauss's assertion, in his sober analysis of the protestant in terms of the historical analysis of rationalization, Weber describes Calvinist Puritans as an image of homeless orphan. The meaningful structure within this image is similar to "schizophrenia", but it is understood by Weber as a relationship of innere Verwandtschaft. This image and its corresponding structure are further clarified in Weber's later comparative study on civilization between China and European civilization. Similarly, this homeless orphan image of protestant and the corresponding structure are also in his works on the methodology of social science, and become the required ethos of science, especially for sociology as he understood it. This "understanding" resonates with modern society, modern university system and the production of modern knowledge. It has its origin in its own civilization. Finally, this paper argues that Weber's understanding of science and vocation, reflected in his lecture on Science as a Vocation, has this image of homeless orphan and structure of affinity as its essential inner substance.From the comparative perspective of home and homeless, this paper argues that, in Weber's thoughts, there is an intrinsic affinity between the image of homeless orphan and science as a vocation. Studies on this affinity offer an important clue for us to understand Weber's thoughts and to reflect the subjectivity building of China's social science.

Key words: home, homeless, orphan, vocation, science
