A new wave of evidentialist theorizing concedes that evidentialism may be extensionally incorrect as an account of all-things-considered rational belief. Nevertheless, these _newer evidentialists_ maintain that there is an importantly distinct type of epistemic rationality about which evidentialism may be the correct account. I argue that natural ways of developing the newer evidentialist position face opposite problems. One version, due to Christensen (Philos Phenomenol Res 103:501–517, 2021), may correctly describe what rationality requires, but does not entail the existence of a (...) distinctively epistemic type of rationality. Another version, due to Maguire and Woods (Philos Rev 129:211–249, 2020), characterizes a normative concept that is both distinct and epistemic, but struggles to explain why this concept should be classified as a type of rationality. I conclude that the newer evidentialist strategy of extensional compromise may be less favorable to evidentialism than previously supposed. (shrink)

Scale-based models of weighing reasons face challenges concerning the context sensitivity of weight, the aggregation of weight, and the methodology for determining what the weights of reasons are. I resolve these challenges.

The metaphor of weighing reasons brings to mind a single (double-pan balance) scale. The reasons for φ go in one pan and the reasons for ~φ go in the other. The relative weights, as indicated by the relative heights of the two pans of the scale, determine the deontic status of φ. This model is simple and intuitive, but it cannot capture what it is to weigh reasons correctly. A reason pushes the φ pan down toward permissibility (has justifying weight) (...) only insofar as it pushes the ~φ pan up toward impermissibility (has requiring weight). Thus, Single Scale is committed to Single Proportion (first pass): all reasons have the same proportion of justifying and requiring weight. Many normative theories reject Single Proportion, and they are not thereby confused about how to weigh reasons. One can be mistaken about the weight of a reason without being confused about how reasons are to be weighed. Single Scale is problematic, not because it appeals to the image of a scale, but because it appeals to the image of a single scale. We need two scales to capture what it is to weigh reasons correctly. (shrink)

[Significantly updated in Chapter 7 of Awareness and the Substructure of Knowledge] Many have found it plausible that knowledge is a constitutively normative state, i.e. a state that is grounded in the possession of reasons. Many have also found it plausible that certain cases of proprioceptive knowledge, memorial knowledge, and self-evident knowledge are cases of knowledge that are not grounded in the possession of reasons. I refer to these as cases of basic knowledge. The existence of basic knowledge forms a (...) primary objection to the idea that knowledge is a constitutively normative state. In what follows I offer a way through the apparent dilemma of having to choose between either basic knowledge or the normativity of knowledge. The solution involves homing in on a state of awareness (≈non-accidental true representation) that is distinct from knowledge and which in turn grounds the normativity of knowledge in a way that is fully consistent with the existence of basic knowledge. An upshot of this is that externalist theories of knowledge turn out to be fully compatible with the thesis that knowledgeable beliefs are always beliefs that are justified by the reasons one possesses.

[Significantly updated in Chapter 6 of Awareness and the Substructure of Knowledge] In order for a reason to justify an action or attitude it must be one that is possessed by an agent. Knowledge-centric views of possession ground our possession of reasons, at least partially, either in our knowledge of them or in our being in a position to know them. On virtually all accounts, knowing P is some kind of non-accidental true belief that P. This entails that knowing P (...) is a kind of non-accidental true representation that P. I outline a novel theory of the epistemic requirement on possession in terms of this more general state of non-accidental true representation. It is just as well placed to explain the motivations behind knowledge-centric views of possession, and it is also better placed to explain the extent of the reasons we possess in certain cases of deductive belief-updates and cases involving environmental luck. I conclude with three reflections. First, I indicate how my arguments generate a dilemma for Errol Lord’s view that possessing reasons is just a matter of being in a position to manifest one’s knowledge how to use them. Second, I explain how my view can simultaneously manage cases of environmental luck without falling prey to lottery cases. Finally, I sketch the direction for a further range of counterexamples to knowledge-centric theories of possession. (shrink)

Contingent negative existentials give rise to a notorious paradox. I formulate a version in terms of metaphysical grounding: nonexistence can't be fundamental, but nothing can ground it. I then argue for a new kind of solution, expanding on work by Kit Fine. The key idea is that negative existentials are contingently zero-grounded – that is to say, they are grounded, but not by anything, and only in the right conditions. If this is correct, it follows that grounding cannot be an (...) internal relation, and that no complete account of reality can be purely fundamental. (shrink)

Can quite different values be rationally weighed against one another? Can the value of one thing always be ranked as greater than, equal to, or less than the value of something else? If the answer to these questions is no, then in what areas do we find commensurability and comparability unavailable? And what are the implications for moral and legal decision making? This book struggles with these questions, and arrives at distinctly different answers.".

This paper discusses varieties of normative phenomena, ranging from morality, to epistemic justification, to the rules of chess. It canvases a number of distinctions among these different normative phenomena. The most significant distinction is between formal and authoritative normativity. The prior is the normativity exhibited by any standard one can meet or fail to meet. The latter is the sort of normativity associated with phenomena like the "all-things-considered" ought. The paper ends with a brief discussion of reasons for skepticism about (...) authoritative normativity. (shrink)

Events between which we have no epistemic reason to discriminate have equal epistemic probabilities. Bertrand’s chord paradox, however, appears to show this to be false, and thereby poses a general threat to probabilities for continuum sized state spaces. Articulating the nature of such spaces involves some deep mathematics and that is perhaps why the recent literature on Bertrand’s Paradox has been almost entirely from mathematicians and physicists, who have often deployed elegant mathematics of considerable sophistication. At the same time, the (...) philosophy of probability has been left out. In particular, left out entirely are the philosophical ground of the principle of indifference, the nature of the principle itself, the stringent constraint this places on the mathematical representation of the principle needed for its application to continuum sized event spaces, and what these entail for rigour in developing the paradox itself. This book puts the philosophy and its entailments back in and in so doing casts a new light on the paradox, giving original analyses of the paradox, its possible solutions, the source of the paradox, the philosophical errors we make in attempting to solve it and what the paradox proves for the philosophy of probability. The book finishes with the author’s proposed solution—a solution in the spirit of Bertrand’s, indeed—in which an epistemic principle more general than the principle of indifference offers a principled restriction of the domain of the principle of indifference.

I extend theories of nonmonotonic reasoning to account for reasons allowing free choice. My approach works with a wide variety of approaches to nonmonotonic reasoning and explains the connection between reasons for kinds of action and reasons for actions or subkinds falling under them. I use an Anderson–Kanger reduction of reason statements, identifying key principles in the logic of reasons.

My purpose here is to describe a type of argument characterized by the fact that one of its premises is a directive—i.e. what is expressed by a directive sentence: a general instruction how to proceed or act. This directive premise brings an ostensive mechanism for the inclusion of visual or multimodal elements in an argument. If an argument is an invitation to inference, by using such a directive utterance the addresser is inviting the addressee to make an inference from an (...) image, not from a proposition. Hence I will call them arguments from ostension or from deixis. (shrink)

Normative reasons are of constant importance to us as agents trying to navigate through life. For this reason it is natural and vital to ask philosophical questions about reasons and the normative realm. This thesis explores various issues concerning reasons and normativity. The thesis consists of five free-standingpapers and an extended introduction. The aim of the extended introduction is not merely to situate the papers within a wider philosophical context but also to provide an overview of some of the central (...) research questions concerning reasons and normativity. The introduction is divided into five chapters. Chapter 1 introduces and outlines the dissertation. Chapter 2 concerns the issue of what a reason is and what different types of reasons there are, such as pro tanto reasons and overall reasons. Chapter 3 discusses the frequently employed weighing metaphor, i.e. that reasons have a certain weight and can be weighed against the weight of other reasons. Chapter 4 covers how reasons relate to other normative notions such as ought, value, and obligation. For example, it discusses whether it is the case that for something to be valuable just is for there to be reasons to favor it. Chapter 5 concludes the introduction by briefly exploring how it all relates.The thesis can be said to be embedded in a recent research trend within philosophy of normativity that has a distinguished focus on reasons.The five papers deal with various issues concerning reasons and normativity. Paper I argues for a novel and theoretically parsimonious way to understand background conditions for values and reasons. Paper II explores an interpretation of the distinction between subjectivism and objectivism about reasons and value so as to accommodate that the distinction does not commit either party to certain first order claims about what reasons there are or what makes objects valuable. Paper III discusses the dictum ‘ought implies can’and how to properly interpret the ‘can’. Paper IV defends principles according to which what we ought and have reasons to do transmit from ends to the necessary means of that action. Paper V analyzes how the Fitting Attitudes analysis of value should best understand degrees of value. (shrink)

I introduce a new version of Moral Error Theory, which I call Type-B Moral Error Theory. According to a Type-B theorist there are no facts of the kind required for there to be morality in stricto sensu, but there can be irreducible ‘normative’ properties which she deems, strictly speaking, to be morally irrelevant. She accepts that there are instrumental all things considered oughts, and categorical pro tanto oughts, but denies that there are categorical all things considered oughts on pain of (...) requiring ‘queer’ facts to obtain. I detail the most central motivation of this version of the theory against its more traditional rival, according to which there are no irreducible normative properties at all. The motivation is that it, unlike its rival, can successfully be defended against the notorious charge of self-defeat. (shrink)

The article argues that there are different ways of justifying suspension of judgement. We suspend judgement not only privatively, that is, because we lack evidence, but also positively, that is, because there is evidence that provides reasons for suspending judgement: suspension is more than the rational fallback position in cases of insufficient evidence. The article applies the distinction to recent discussions about the role of suspension for inquiry, Turri's puzzle about withholding, and formal representations of suspension.
