Since the publication of Between Facts and Norms, Habermas’s concept of communicative power has been the topic of significant discussion. This article contributes to this conversation by examining Habermas’s account of what makes communication powerful. I argue that Habermas’s conception of communicative power describes a nonviolent and noninstrumental mode of acting and being with others in language. This mode of engagement underwrites a conception of power that is structurally different from willing, one that builds meaningful worlds and (trans-)forms those engaging (...) in communicative procedures. In drawing out this aspect of Habermas’s conception, I show that he is not a rationalist and proceduralist whose account of communicative procedures protects decision-making from irrational aesthetic powers. Rather, he presents communication as a mimetic achievement, a set of aesthetic practices and experiences that affectively alter its participants. With this position, Habermas makes an important contribution to and not just against the analysis of the aesthetic dimensions of political life. In casting communication as a mimetic achievement, Habermas presents an account of how communication opens worlds and forms subjects. Yet since these aspects of communication arrive in linguistic form, he can also examine affective and aesthetic experiences within discursive procedures. We can understand world-opening and aesthetic (trans-)formation as an essential part of democratic politics while also identifying the perspectives and resources by which actors can reflect on and critically evaluate whether an opinion is justified or whether a political project is worth pursuing.
