This paper critically examines Coliva and Palmira’s characterization of the disagreement between Humean skeptics and hinge epistemologists as a distinctive kind of conceptual disagreement. Humean skepticism requires evidential justification for all rational beliefs, presenting a narrower conception of rationality. This contrasts with constitutivist hinge epistemology, which posits that our unwarranted hinge propositions — the basic certainties which makes the justifications for ordinary empirical propositions possible — are constitutive of the concept of epistemic rationality, thus they are also rationally accepted by us. Coliva and Palmira (2020, 2021) argue that this divergence reflects a conceptual disagreement over the conception of epistemic rationality, implying a dispute about how the concept of epistemic rationality should be understood. Their strategy is two-fold: they first mentioned Stroud’s (2019) categorization of conceptual disagreement, but contended that the disagreement between Humean skeptics and hinge epistemologists represents a novel kind of conceptual disagreement that Stroud’s categorization cannot encompass. They suggest this new framing allows for a rational resolution of the disagreement; second, they argue that the extended conception of rationality is superior because it coherently accounts for the rationality of our epistemic practices. However, I contend that both parts of their two-fold strategy fail. Even if the disagreement is conceptual, it can be understood as a type of disagreement within Stroud’s categorization; therefore, it does not represent a novel type of disagreement. Additionally, I argue that they misinterpret the skeptic’s stance. Skeptics do not assume that our epistemic practices are rational; rather, they doubt the rationality of these practices and the possibility of knowledge. Therefore, for a skeptic, there is no advantage from a conceptual proposal that makes a coherent account of the alleged rationality of our epistemic practices.
