Scholars have long recognized the existence of myriad widespread deep disagreements on values, justice, morality, and ethics. In order to come to terms with such deep disagreements, resistant to rational solution, this article asserts the need for developing an ethics of disagreement. The reality that theoretical disagreements often turn into practical conflicts is a major justification for why such an ethics is necessary. This paper outlines an ethics of deep disagreement that is primarily conceived of as a form of virtue (...) ethics. Such an ethics asks opposing parties in moral and intellectual conflicts to acknowledge that (a) deep disagreements exist, (b) opposing positions should be recognized as worthy of respect, and that (c) one should seek dialogue and mutual understanding. This ethical approach conceives of toleration as a moral and political virtue and presents an argument for toleration based on deep disagreements. (shrink)
