Book excerpt: Democratic Speech in Divided Times offers a comprehensive account of the norms that should govern public discourse in circumstances marked by deep and often unjust social divisions. Part I investigates what forms of democratic speech are desirable in these settings. This part shows, firstly, that some forms of public discourse that are symptomatic of division can nevertheless play a crucial democratic function. In particular, it argues that emotionally charged speech--and most notably, speech voicing deep anger--plays a fundamental role in overcoming entrenched epistemic divisions and in facilitating the exchange of shared reasons. This part also examines how, in contrast, other characteristic features of the public discourse of divided societies endanger democratic life. Here, the argument considers the proliferation of hate speech and misinformation, and examines what forms of democratic speech should be used to combat them. Part II considers how realistic the foregoing account of public discourse is. Specifically, it assesses the complications that arise from intergroup antipathy, pervasive political ignorance, and the fragmentation of the public sphere. The normative picture of public discourse that this book defends can largely withstand these problems. And, while these social conditions do qualify the value of democratic speech in some respects, they are at least as problematic for political ideals that give up on inclusive democratic speech altogether. Accordingly, while realising the ideal of democratic speech that this book outlines is challenging, we should not lose patience with this task.
