In the current debate on the relation between how-possibly explanations (HPEs) and understanding, two seemingly irreconcilable positions have emerged, which either deny or assert HPEs’ contribution to understanding. We argue, in contrast, that there is substantial room for reconciliation between these positions. First, we show that a shared assumption is unfounded: HPEs can be...
How can a persisting object change whilst remaining the same object? Lewis, who frames this as the problem of temporary intrinsics, presents us with the perdurance solution: objects persist by having temporal parts which may have differing properties. And in doing so he characterises the opposing view as persisting but not by having temporal parts – a view he calls endurance. But...
My interest is in an apparent tension between two epistemological theses. The first is veritism, which is roughly the claim that truth is the fundamental epistemic good. The second is the idea that understanding is the proper goal of inquiry. The two theses seem to be in tension because the former seems to imply that the proper goal of inquiry should be truth rather than...
A jury needs “proof beyond a reasonable doubt” in order to convict a defendant of a crime. The standard is vexingly difficult to pin down, but some legal epistemologists have given this account: knowledge is the standard of legal proof. On this account, a jury should deliver a guilty verdict just in case they know that the defendant is guilty. In this paper, I’ll argue that legal...
How do we control what we do not do? What are the relevant guiding mental states when an agent intentionally omits to perform an action? I argue that what happens when an agent intentionally omits is a two-part metacognitive process in which a representation of an action is brought to the agent’s mind for further processing and evaluated by her as something not to be done...
How reliable are causal inferences in complex empirical scenarios? For example, a physician prescribes a drug to a patient, and then the patient undergoes various changes to their symptoms. They then increase their confidence that it is the drug that causes such changes. Are such inferences reliable guides to the causal relation in question, particularly when the physician can...
Climate change is one of the most important issues we are currently facing. There are many ways in which states can fight climate change. Some of them involve interfering with citizens’ personal lives. The question of whether such interference is justified is under-explored in philosophy. This paper focuses on a specific aspect of people’s personal lives, namely their...
According to directionalism, non-symmetric relations are distinct from their converses. Kit Fine (2000a) argues that the directionalist faces a dilemma; they must either (i) reject the principle Uniqueness, which states that no completion (fact, state of affairs, or proposition) is a completion of more than one relation, or (ii) reject the principle Identity, which states that...
The value alignment problem for artificial intelligence (AI) asks how we can ensure that the “values”—i.e., objective functions—of artificial systems are aligned with the values of humanity. In this paper, I argue that linguistic communication is a necessary condition for robust value alignment. I discuss the consequences that the truth of this claim would have for research...
It is widely held that metaphysical modality is the broadest non-epistemic, alethic modality, and that a posteriori modal essentialist truths, like that gold has atomic number 79, enjoy the necessity of the broadest alethic modality. One prominent argument for these conclusions—given by Cian Dorr, John Hawthorne, and Juhani Yli-Vakkuri—rests upon an extremely dubious premise...
This paper considers two recent views on the structure of justification and closure of knowledge by Ernest Sosa. It provides reason to believe that neither view is ultimately viable and sketches a better alternative.
Silence sometimes constitutes moral complicity. We see this when protestors take to the streets against racial injustice. Think of signs with the words: “Silence is complicity.” We see this in instances of sexual harassment, when we learn that many knew and said nothing. We see this in cases of wrongdoing within a company or organization, when it becomes clear that many were...
Consider the class of contextually sensitive expressions whose context invariant meanings arguably do not suffice to secure semantic values in context. Demonstratives and demonstrative pronouns are the examples of such expressions that have received the most attention from philosophers. However, arguably this class of contextually sensitive expressions includes among other...
In practical rationality, if two reasons for alternative actions are tied, then either action is *permissible*. In epistemic rationality, we get the Epistemic Ties Datum: if the reasons for belief and disbelief are tied, then withholding judgment is *required*. I argue that this difference is explained by a difference in default biases. Practical rationality is biased toward...
My aim in this paper is to introduce and motivate a general normative framework, which I call feasibilism, and to sketch a view of the relationship between the prescriptive and the hypological in the epistemic domain by drawing on the theoretical resources provided by this framework. I then generalise the lesson to the moral domain. I begin by motivating feasibilism. A wide range...
What is the status of metaphorical meaning? Is it an input to semantic composition or is it derived post-semantically? This question has divided theorists for decades. Griceans argue that metaphorical meaning/content is a kind of implicature that is generated through post-semantic processing. Others, such as the contextualists, argue that metaphorical meaning is an input to...
Often, a health resource distribution (or, more generally, a health policy) ranks higher than another on one value, say, on promoting total population health; and lower on another, say, on promoting that of the worst off. Then, some opine, there need not be a rational determination as to which of the multiple distributions that partially fulfill both one ought to choose...
The dominant practice of AI alignment assumes (1) that preferences are an adequate representation of human values, (2) that human rationality can be understood in terms of maximizing the satisfaction of preferences, and (3) that AI systems should be aligned with the preferences of one or more humans to ensure that they behave safely and in accordance with our values. Whether...
There are two leading theories about the ontology of dreams. One holds that dreams involve hallucinations and beliefs. The other holds that dreaming involves sensory and propositional imagining. I highlight two features of dreams which are more easily explained by the imagination theory. One is that certain things seem to be true in our dreams, even though they are not...
This paper develops and defends novel accounts of accurate and reasonable doubt. We take a cue from Sosa's telic epistemic normative picture to argue that one’s degree of doubt that p is accurate just in case it matches the level of veritic risk involved in believing that p. In turn, on this account, reasonable doubt is doubt that is generated by a properly functioning cognitive...
By definition, the implicit commitment of a formal theory $$\textrm{Th}$$ consists of sentences that are independent of the axioms of $$\textrm{Th}$$ , but their acceptance is implicit in the acceptance of $$\textrm{Th}$$ . In Cieśliński (2017, 2018), the phenomenon of implicit commitments was studied from the epistemological perspective through the lenses of the formal theory of...
Several influential thought experiments from Harman 1973 purport to show that unpossessed evidence can undermine knowledge. Recently, some epistemologists have appealed to these thought experiments in defense of a logically stronger thesis: unpossessed evidence can defeat justification. But these appeals fail to appreciate that Harman himself thought of his examples as Gettier...
Suppose there are no in-principle restrictions on the contents of arbitrarily intelligent agents’ goals. According to “instrumental convergence” arguments, potentially scary things follow. I do two things in this paper. First, focusing on the influential version of the instrumental convergence argument due to Nick Bostrom, I explain why such arguments require an account of...
