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.

The judgment competent reasoners exhibit in deciding when reasoning should not be used to resolve disagreements is eroded by adopting the popular strategy of ascending to higher levels of generality. That strategy encourages disputants to believeoften incorrectly-that they stand on some common ground that can be exploited to reach agreement. But if we regularly assume that we share values and interests with our opponents in seemingly intractable disputes, we risk losing the ability to judge whether or not we share enough. (...) And when we lose track of the difference between promising and unpromising conditions for reasoning, we end up trying to reason at the wrong times. Such reasoning can in turn seriously damage our reasoning skills themselves. (shrink)

In the appropriate contexts reasoning is a powerful tool for producing intersubjective agreement about what counts as the best answer to a question that generates inquiry; sometimes employing arguments can lead to agreement about what is the right answer. In this paper we hope to show, however, that unabashed optimism about the power of argument is misplaced. Such optimism rests on an implausible picture of the power of articulation. Sentences cashed out as reasons to believe another sentence is true cannot (...) bridge large gaps in substantive understanding. A failure to realize this fact, moreover, leads to an uncautious and unreflective optimism about the power of argument that ultimately threatens the very reasons-giving process. What is needed, then, is a much more modest sense of the role of argument. (shrink)
