Deliberative democracy harbors a recurrent tension between full inclusion and intelligible speech. People with profound cognitive disabilities often signify this tension. While liberal deliberative theorists sacrifice inclusion for intelligibility, this exclusion is unnecessary. Instead, by analyzing deliberative locations that already include people with disabilities, I offer two ways to revise deliberative norms. First, the physical presence of disabled bodies expands the value of publicity in deliberative democracy, demonstrating that the publicity of bodies provokes new conversations similar to rational speech acts. (...) Second, the inclusion of people with profound disabilities necessitates a form of collaborative speech in which individuals make claims collaboratively. Habermas offers an ideal site to pursue this analysis because he recognizes the theoretical tension between inclusion and intelligibility and because his personal testimony reveals important insight into the lived experience of disability.

Since its inception, a core aspiration of deliberative democracy has been to enable more and better inclusion within democratic politics. In this article, we argue that deliberative democracy can achieve this aspiration only if it goes beyond verbal forms of communication and acknowledges the crucial role of non-verbal communication in expressing and exchanging arguments. The article develops a multidimensional approach to deliberative democracy by emphasizing the visual, sonic and physical dimensions of communication in public deliberation. We argue that non-verbal modes (...) of communication can contribute to public deliberation when they (1) are used as part of reason-giving processes, (2) enable the inclusion of marginalized actors in public debates and (3) induce reflection and encourage new ways of thinking about the public controversies at hand.
