"With its excellent contributors writing on topical issues of disagreement, this is a very welcome collection. It will attract much interest and should enhance the ongoing debates concerning those issues."--Ernest Sosa, Rutgers University“The essays are uniformly lucid, and the argumentative moves that are considered are well handled. Overall, the essays make a solid contribution to the ongoing disagreements about disagreement…” --Guy Longworth, University of Warwick, UK
