This article introduces Metaphilosophy's special issue on metatheories of disagreement, with the aim of promoting discussion on the nature of disagreement on a metatheoretical level. The contributions to this issue cover the following key topics related to disagreement: faultless disagreement, metaontological disagreement, metalinguistic disagreement, responses to peer disagreement in philosophy, hinge epistemology and deep disagreement, disagreement asymmetry, factual and nonfactual disagreement, and defining disagreement or verbal dispute. This introduction also provides general background on four major topics in order to contextualize the contributions to the special issue: first, the problem of characterizing the subject matter of disagreements; second, the most prominent accounts of deep disagreement, disagreement asymmetry and hinges; third, the notion of faultless disagreement; and finally, the problem of offering different approaches on what disagreements are.
