In their book titled Architectures of Knowledge, Amin and Cohendet (2004) propose an approach to the mobilization of knowledge in the firm, and beyond the firm, in human organizations that place priority on embodied, socially inscribed practices anchored in artefacts. This leads them to largely remodel the theory of collective knowledge mobilization. At the center of this new conceptualization is the community, seen as a place where this intersubjective, social practice is effected. In doing so, they offer a broad, rich, and well-articulated epistemological background that can be called a “praxeology”, and a methodology based on an ethnography, a clinic of the flow of knowledge in organizations. In this text I propose a reading of this conceptualization from a psychologist point of view. I do so by pointing out that there is a important proximity between their epistemological roots (american pragmatism, maturanian and varelian enactionism, situated action, socio-culturalism, and the Science Studies movement) and some works which consider the cognitive processes as being primarly socially inscribed practices instead of brain informational processes. In doing so, I argue the possibility to base this type of reflexion on a meadian perspective.
