The value of Pierre Bourdieu’s theory is proven not only by his recognized position in contemporary social thought, but also numerous polemics, criticism which it faces and proposals of reformulation it inspires. This article presents one of the most important theoretical and research projects related to reinterpretation of Bourdieu’s category – Bernard Lahire’s sociology. It takes as a starting point the proposal to correct the thoughts of the author of Distinction if it comes to studies on social classes and the meaning of the concepts of habitus, cultural capital and reproduction. The article presents Lahire’s ideas in action, as he uses them in his early research. Moreover, the evolution of Lahire’s views is examined starting from continuation to criticism of structural constructivism with L’homme pluriel as culmination. The concept of a polymorphic human is confronted critically with Bourdieu’s work to demonstrate simplifications and limitations of Lahire’s theory. There are also other proposals of reformulation and continuation of the concept of Pierre Bourdieu’s classes.
