Interpersonal disagreement happens all the time. How to properly characterize interpersonal disagreement and how to respond to it are important problems, but the existence of such disagreements at least is obvious. The existence of intrapersonal disagreement, however, is another matter. On the one hand, we do change our minds sometimes, especially when new evidence comes in, and so there is a clear enough sense in which we can be characterized as having disagreements with our past selves. But what about synchronic (...) disagreements with ourselves? Are such cases possible, or is there something about the nature of belief that rules out the possibility of knowingly holding beliefs which cannot be rationally held at the same time? In this paper, I argue that there can be cases of intrapersonal synchronic disagreement, and that such disagreements can be deep, in the same way that interpersonal disagreements can be deep. For intrapersonal disagreements, just like interpersonal disagreements, can be grounded in conflicting frameworks for interpreting and reasoning about the world. I also argue that synchronic intrapersonal disagreements are peer disagreements. The paper ends with a discussion of four possible responses to interpersonal deep disagreements, concluding that if those responses are sometimes rational responses in the interpersonal case, then they are also sometimes rational responses in the intrapersonal case.

In this paper, we bring into focus the level of thought or content in the elucidation of disagreement. We set out the view that disagreement at this level involves a specific form of noncotenability, namely, noncotenability as captured by sense or intension as opposed to reference. We present the challenge that nourishes the alternative referential view and suggest, through examples, that (i) only intensional disagreement is apt to adequately accommodate basic rationality constraints on disagreement, and (ii) it can meet the (...) aforementioned challenge insofar as we discriminate between noncotenability affecting one's concepts, intensionally conceived, and noncotenability affecting merely one's particular understanding of those concepts. We conclude that intensional disagreement is our best choice for an account of disagreement at the level of thought. (shrink)

Philosophical literature has focused on the concept of trust, but often considers distrust merely as an afterthought. Distrust however, because of its pervasive role in our everyday lives, can be quite damaging. Thus, understanding the rationality of distrust is crucial for understanding our testimonial practices. In this paper I analyze whether it is rational or irrational to distrust an informant on the basis of identity bias. My aim is to show that distrust is irrational when based on negative identity bias. (...) First, I adopt Annalisa Coliva’s account of social hinge epistemology where it is rationally required to assume certain basic presuppositions, such that people are generally reliable informants, to obtain propositional justification and participate in the testimonial practice. Secondly, I show how distrust based on negative identity bias can spread across other domains of interaction and jeopardize the testimonial practice as we fail to assume that people are generally reliable informants. Thirdly, I argue that considering bias as a defeater is beneficial to maintain the claim that bias-based distrust is irrational, as it prevents the acquisition of propositional justification. Finally, I show that distrust is rational when based on evidence and reason that the speaker is not reliable or sincere. (shrink)
