Sometimes we disagree because of fundamental differences in what we treat as reasons for belief. Such are ‘deep disagreements'. Amongst the questions we might ask about deep disagreement is the epistemic normative one: how ought one to respond to disagreement, when that disagreement is deep. This paper addresses that question. According to the position developed, how one ought to respond to deep disagreement depends upon two things: (i) Whether one remains, in the context of disagreement, permitted to trust oneself in following one's epistemic norms and in relation to that (ii) whether one has the shared stock of social-epistemic experiences with followers of one's rival's norms such that one could reasonably be expected to see their way of doing things as a genuine epistemic alternative to one's own. Section 1 introduces a model of deep disagreement such that deep disagreements occur when disputants disagree because they follow different epistemic norms. Section 2 surveys the possible theoretical stances to take towards the epistemic-normative question. Section 3 develops an account of what it is to follow an epistemic norm. Section 4 applies this conception of norm-following to the epistemic-normative question. Section 5 discusses two points of clarification.

This paper offers a defense of ‘publishing without belief’ (PWB) – the view that authors are not required to believe what they publish. I address objections to the view ranging from outright denial and advocacy of a belief norm for publication, to a modified version that allows for some cases of PWB but not others. I reject these modifications. In doing so, I offer both an alternative story about the motivations for PWB and a diagnosis of the disagreement over its permissibility. The original defense focused on consequentialist reasons for allowing PWB, offering mostly defensive arguments against potential criticisms. But I argue that once we shift our focus to the reasons why authors might be prone to PWB, we see a difference in two types of motivation: whereas I imagine PWB as arising from underconfident agents, critics point to cagey or nefarious authorial practices, or authors’ failure to clarify their own degrees of belief. Underlying the debate over norms of philosophical publishing, we find two different conceptions of philosophy itself.

Post-truth politics has been diagnosed as harmful to both knowledge and democracy. I argue that it can also fundamentally undermine epistemic autonomy in a way that is similar to the manipulative technique known as gaslighting. Using examples from contemporary politics, I identify three categories of post-truth rhetoric: the introduction of counternarratives, the discrediting of critics, and the denial of more or less plain facts. These strategies tend to isolate people epistemically, leaving them disoriented and unable to distinguish between reliable and unreliable sources. Like gaslighting, post-truth politics aims to undermine epistemic autonomy by eroding someone's self-trust, in order to consolidate power. Shifting the focus to the effects on the victim allows for new insights into the specific harms of post-truth politics. Applying the concept of gaslighting to this domain may also help people recognize a pernicious dynamic that was invisible to them before, giving them an important tool to resist it.

What is epistemic self-trust? There is a tension in the way in which prominent accounts answer this question. Many construe epistemic trust in oneself as no more than reliance on our sub-personal cognitive faculties. Yet many accounts – often the same ones – construe epistemic trust in others as a normatively laden attitude directed at persons whom we expect to care about our epistemic needs. Is epistemic self-trust really so different from epistemic trust in others? I argue that it is not. We certainly do rely on our cognitive faculties to achieve epistemic ends; but I argue that we also have the normatively rich sort of epistemic trust in ourselves. Moreover, there is a theoretical need for this normatively rich notion of epistemic self-trust: positing it yields the best account of how we secure important epistemic goods, including knowledge and recognition as knowers. I argue this by giving an account of epistemic trust in others and showing that it can be generalized to epistemic trust in oneself.
