This paper deals with the status of Pierre Bourdieu’s incorporating theory within the expanse of the social sciences. First, it describes the philosophy relational as a bridge between objectivism and subjectivism. Then, it tries to show the origins of this theory in the theory of physical field and the theory of psychological field. Finally, the paper focuses on Bourdieu’s theory and attempts at an explication of his theory of practice by illustrating the two concepts of habitus and field. Thus, the relational substances of these two concepts are discussed in this paper. Here, habitus and field are defined in relation to each other. Ultimately, we try to arrive at a deeper understanding of Bourdieu’s conceptualizations, in the form of a powerful theoretical apparatus, for the analysis and explanation of various subjects in different fields.
