The concept of deep disagreement is useful for highlighting skills and resources required for reasons-giving to be effective in restoring cooperative or joint action. It marks a limit. When it is instead understood as a challenge to be overcome by using reasons, it leads to significant practical, theoretical, and moral distortions.

I will connect the literature on deep disagreements with the literature on trust to construct a two-dimensional picture of the limits of argument. Argumentation and trust are important to the functioning of society, but each sets different expectations for when arguments can and should be used to resolve disagreements. When trust is factored in, we see a more nuanced picture of which disagreements will remain too deep for objective argument. Affective and social aspects of argument are not independent of procedure (...) and content. (shrink)
