Although we have to welcome the renewed interest in socio-materiality in organization studies, I claim that we are yet to understand what taking matter seriously really means. The mistake we especially need to stop making consists of automatically associating matter to something that can be touched or seen, that is, something tangible or visible, an association that irremediably leads us to recreate a dissociation between the world of human affairs and the so-called material world. To address this issue, I mobilize a communication-centered perspective to elaborate that (1) materiality is a property of all (organizational) phenomena and that (2) studying these phenomena implies a focus on processes of materialization, that is, ways by which various beings come to appear and make themselves present throughout space and time. In the paper I conceptualize the contours of these materialization processes and discuss the implications of this perspective on materiality for organizational theory and research.
