Most theories of learning consider inferring a function f from either observations about f or, questions about f. We consider a scenario whereby the learner observes f and asks queries to some set A. If I is a notion of learning then I[A] is the set of concept classes I-learnable by an inductive inference machine with oracle A. A and B are I-equivalent if I[A] = I[B]. The equivalence classes induced are the degrees of inferability. We prove several results about (...) when these degrees are trivial, and when the degrees are omniscient. (shrink)

Talk about Beliefs presents a new account of beliefs and of practices of reporting them that yields solutions to foundational problems in the philosophies of...

Negative facts get a bad press. One reason for this is that it is not clear what negative facts are. We provide a theory of negative facts on which they are no stranger than positive atomic facts. We show that none of the usual arguments hold water against this account. Negative facts exist in the usual sense of existence and conform to an acceptable Eleatic principle. Furthermore, there are good reasons to want them around, including their roles in causation, chance-making (...) and truth-making, and in constituting holes and edges. (shrink)

In this paper I explore how and why personal identity might be essentially narrative in nature. My topic is the question of personal identity in the strict sense of identity—the question of which person you are, and how that person is extended in space, time, and quality. In this my question appears to contrast with the question of personal identity in the sense sought by teenagers and sufferers of mid-life crises who are trying to ‘find themselves’. But in fact it (...) will be key to my argument that these questions are not distinct and independent. Whereas Parfit was concerned, in his work on personal identity, with how he was extended over time, the teenager who is finding themselves is concerned with how they are extended in quality. Indeed, the core of my argument is that because narrative is the key to understanding how we are extended in quality, and quality is just one more dimension along which we are extended, along with space and time, narrative must also be the clue as to how we are extended in space and time. You, I will argue, are the protagonist in the best story of your life. (shrink)

Gossip is often serious business, not idle chitchat. Gossip allows those oppressed to privately name their oppressors as a warning to others. Of course, gossip can be in error. The speaker may be lying or merely have lacked sufficient evidence. Bias can also make those who hear the gossip more or less likely to believe the gossip. By examining the social functions of gossip and considering the differences in power dynamics in which gossip can occur, we contend that gossip may (...) be not only permissible but virtuous, both as the only reasonable recourse available and as a means of resistance against oppression.

What is the function of concepts pertaining to meaning in socio-linguistic practice? In this study, the authors argue that we can approach a satisfactory answer by displacing the standard picture of meaning talk as a sort of description with a picture that takes seriously the similarity between meaning talk and various types of normative injunction. In their discussion of this approach, they investigate the more general question of the nature of the normative, as well as a range of important topics (...) specific to the philosophy of language.

Uncovers the methodological principles that govern interpretive change.

Despite its many advantages as a metaethical theory, moral expressivism faces difficulties as a semantic theory of the meaning of moral claims, an issue underscored by the notorious Frege-Geach problem. I consider a distinct metaethical view, inferentialism, which like expressivism rejects a representational account of meaning, but unlike expressivism explains meaning in terms of inferential role instead of expressive function. Drawing on Michael Williams’ recent work on inferential theories of meaning, I argue that an appropriate understanding of the pragmatic role (...) of moral discourse—the facilitation of coordinated social behavior—suggests the kind of inferences we should expect terms with this function to license. I offer a sketch of the inferential roles the moral ‘ought’ plays, and argue that if we accept that the relevant inferential roles are meaning-constitutive, we will be in a position to solve the Frege-Geach problem. Such an inferentialist solution has advantages over those forwarded by expressivists such as Blackburn and Gibbard. First, it offers a more straightforward explanation of the meaning of moral terms. It also gives simple answers to at least two semantic worries that have vexed contemporary expressivists—the “problem of permissions” and the commitment to “mentalism”, both of which I argue are problems that don’t get traction with an inferentialist approach. I conclude by considering ways in which this approach can be expanded into a more robust semantic account. (shrink)

In this paper we explore the connections between ethics and decision theory. In particular, we consider the question of whether decision theory carries with it a bias towards consequentialist ethical theories. We argue that there are plausible versions of the other ethical theories that can be accommodated by “standard” decision theory, but there are also variations of these ethical theories that are less easily accommodated. So while “standard” decision theory is not exclusively consequentialist, it is not necessarily ethically neutral. Moreover, (...) even if our decision-theoretic models get the right answers vis-`a-vis morally correct action, the question remains as to whether the motivation for the non-consequentialist theories and the psychological processes of the agents who subscribe to those ethical theories are lost or poorly represented in the resulting models.

In the clinical setting, questions of medical ethics raise a host of perplexing problems, often complicated by conflicting perspectives and the need to make immediate decisions. In this volume, bioethicists and physicians provide a nuanced, in-depth approach to the difficult issues involved in bioethics consultation. Addressing the needs of researchers, clinicians, and other health professionals on the front lines of bioethics practice, the contributors focus primarily on practical concerns -- whether ethics consultation is best done by individuals, teams, or committees (...) how an ethics consult service should be structured the need for institutional support and techniques and programs for educating and training staff -- without neglecting more theoretical considerations, such as the importance of character or the viability of organizational ethics.

In this article I develop a model of theoretical understanding in science. This is a philosophical theory that specifies the conditions that are both necessary and sufficient for a scientist to satisfy the construction ‘S understands theory T ’. I first consider how this construction is preferable to others, then build a model of the requisite conditions on the basis of examples from elementary physics. I then show how this model of theoretical understanding can be made philosophically robust and provide (...) a more sophisticated account than we see from models of a similar kind developed by those working in the psychology of physics and artificial intelligence. 1 Introduction2 The Explicandum/Analysandum3 Analysis of ‘S understands T’ 4 The Inferential Model4.1 Which problems are we talking about?4.2 Does the solution have to be true?4.3 Does each cycle have to be correct for S to understand T?4.4 What is problem-solving reliability?4.5 Does every specific inference of a cycle have to be correct?4.6 Does each inference have to use a principle that is part of the theory?5 Theoretical Understanding and Conceptual Expertise: Empirical Considerations6 Conclusion: Inferential Model of Scientific Understanding and Our Traditional Problems.

I argue that using information from a cognitive representation to guide the performance of a primary task is sufficient for intellectual attention, and that this account of attention is endorsed by scientists working in the refreshing, n-back, and retro-cue paradigms. I build on the work of Wayne Wu, who developed a similarly motivated account, but for perceptual attention rather than intellectual attention. The way that I build on Wu’s account provides a principled way of responding to Watzl’s challenge to Wu, (...) according to which Wu’s style of account is unintuitively broad. The fact that I find unity in the practice of science puts us in a position to resist the claim that scientists studying intellectual attention are frequently failing to study the same thing.

In this paper I present an argument for belief in inconsistent objects. The argument relies on a particular, plausible version of scientific realism, and the fact that often our best scientific theories are inconsistent. It is not clear what to make of this argument. Is it a reductio of the version of scientific realism under consideration? If it is, what are the alternatives? Should we just accept the conclusion? I will argue (rather tentatively and suitably qualified) for a positive answer (...) to the last question: there are times when it is legitimate to believe in inconsistent objects. (shrink)

Cultural influences are pervasive throughout human behaviour, and as human–robot interactions become more common, roboticists are increasingly focusing attention on how to build robots that are culturally competent and culturally sustainable. The current treatment of culture in robotics, however, is largely limited to the definition of culture as national culture. This is problematic for three reasons: it ignores subcultures, it loses specificity and hides the nuances in cultures, and it excludes refugees and stateless persons. We propose to shift the focus (...) of cultural robotics to redefine culture as an emergent phenomenon. We make use of three research programmes in the social and cognitive sciences to justify this definition. Consequently, cultural behaviour cannot be explicitly programmed into a robot, rather, a robot must be designed with the capability to participate in the interactions that lead to the arising of cultural behaviour. In the final part of the paper, we explore which capacities and abilities are the most salient for a robot to do this. (shrink)

Let us begin with the simple observation that applied mathematics can be very tough! It is a common occurrence that basic physical principle instructs us to construct some syntactically simple set of differential equations, but it then proves almost impossible to extract salient information from them. As Charles Peirce once remarked, you can’t get a set of such equations to divulge their secrets by simply tilting at them like Don Quixote. As a consequence, applied mathematicians are often forced to pursue (...) roundabout and shakily rationalized expedients if any useful progress is to be made. Often these provisional and quasi-empirical procedures within applied mathematics loom large in motivating the “anti-realist” or “anti-unificationist” conclusions of Nancy Cartwright and allied authors.

Amidst the wealth of literature on the topic of moral distress in nursing, a single citation is ubiquitous, Andrew Jameton’s 1984 book Nursing practice. The definition Jameton formulated reads ‘... moral distress arises when one knows the right thing to do, but institutional constraints make it nearly impossible to pursue the right course of action’. Unfortunately, it appears that, despite the frequent use of Jameton’s definition of moral distress, the definition itself remains uncritically examined. It seems as if the context (...) of how moral distress arises (i.e. anger, frustration etc.) has been co-opted as its definition. This current work suggests that the current definition is not moral distress as defined by Jameton, but rather, in large part, nursing’s discomfort with moral subjectivity in end-of-life decision making. A critical examination of how the Catholic tradition’s normative ethical framework accounts for moral subjectivity in end-of-life decision making serves to aid nursing’s discomfort and as a starting point to recontextualize moral distress.

Douglas Portmore has recently argued in this journal for a "promising result" – that combining teleological ethics with "evaluator relativism" about the good allows an ethical theory to account for deontological intuitions while "accommodat[ing] the compelling idea that it is always permissible to bring about the best available state of affairs." I show that this result is false. It follows from the indexical semantics of evaluator relativism that Portmore's compelling idea is false. I also try to explain what might have (...) led to this misunderstanding. (shrink)

In this commentary, I advocate for strict relations between Marr's levels of analysis. Under a strict relationship, each level is exactly implemented by the subordinate level. This yields two benefits. First, it brings consistency for multilevel explanations. Second, similar to how a sculptor chisels away superfluous marble, a modeler can chisel a computational-level model by applying constraints. By sculpting the model, one restricts the set of possible algorithmic- and implementational-level theories.

The idea that natural language grammar and planned action are relatedsystems has been implicit in psychological theory for more than acentury. However, formal theories in the two domains have tendedto look very different. This article argues that both faculties sharethe formal character of applicative systems based on operationscorresponding to the same two combinatory operations, namely functional composition and type-raising. Viewing them in thisway suggests simpler and more cognitively plausible accounts of bothsystems, and suggests that the language faculty evolved in the (...) speciesand develops in children by a rather direct adaptation of a moreprimitive apparatus for planning purposive action in the world bycomposing affordances of objects or tools. Theknowledge representation that underlies such planning is alsoreflected in the natural language semantics of tense, mood, andaspect, which the paper begins by arguing provides the key tounderstanding both systems.

This chapter discusses various senses in which mathematics is applied to the material world. It distinguishes between canonical and noncanonical applications of mathematics, the former being those for which the mathematics was developed to deal with in the first place. It also distinguishes between empirical and nonempirical applications, thus yielding four different kinds of applications. Examples of each are provided, and philosophical problems connected with each are treated.

The Explanatory Model of Scientific Understanding is a deflationary thesis recently advocated by Kareem Khalifa. EMU is committed to two key ideas: all understanding-relevant knowledge is propositional in nature; and the abilities we use to generate understanding are merely our usual logical reasoning skills. In this paper I provide an argument against both ideas, suggesting that scientific understanding requires a significant amount of non-propositional knowledge not captured by logical relations. I use the Inferential Model of Scientific Understanding to reveal how (...) we can better represent what constitutes understanding a scientific event. In particular, this model accounts for not only logical and probabilistic inferences, but also those conceptual associations and categorizations we must make to comprehend an explanation. (shrink)

Propositional Attitudes defends an account of ‘believes’ on which the verb is contextually sensitive. x believes that S says that x has a belief which is ‘well rendered’ or acceptably translated by S; since contextually variable information about what makes for a good translation helps determine the extension of ‘believes,’ the verb is contextually sensitive. Sider and Soames criticize this account. They say it has unacceptable consequences in cases in which we make multiple ascriptions of belief to a single individual (...) - as happens, for example, when we say that Odile believes such and such, that the woman in the corner believes so and so, but are ignorant of the identity of Odile and the woman in the corner.I will distinguish two objections along these lines, and argue that neither is forceful. The objections differ as to whether or not the speaker mistakenly presupposes that the believers under discussion are distinct. (shrink)

Within the Anglo-American world, economic liberalism is generally viewed as having only one progenitor—Adam Smith—and one offspring—neoliberalism. But it actually has two. The work of G. W. F. Hegel was also very influential on the development of economic liberalism, at least in the German-speaking world, and the most powerful contemporary instantiation of economic liberalism within that world is not neoliberlaism, but ordoliberalism, although this is generally unknown and certainly unacknowledged outside of Continental Europe. Accordingly, what I am going to be (...) doing in this piece is trying to bring ordoliberalism more directly into the light—I will argue that by comparing and contrasting the views of Smith and Hegel or at least between how Smith and Hegel tend to be currently (mis)understood, we can better understand both the roots and the nature of these two contemporary incarnations of economic liberalism, and the light this sheds, in turn, brings some interesting and important features of these two contemporary theories into view. From Smith, for example, neoliberals took the idea of the invisible hand, although I am going to argue that contemporary advocates of invisible hand theory have largely misconstrued or at the very least overstated the significance of this metaphor. From Hegel, in contrast, ordoliberals took the idea of the civil society, and I will argue that the civil society is a much better metaphor not only for Hegel's but also for Smith's views. Indeed, I will argue that ordoliberalism, not neoliberalism, is a better and more coherent instantiation of economic liberalism than neoliberalism could ever be. (shrink)

Motivational internalism about moral judgments is the plausible view that accepting a moral judgment is necessarily connected to motivation motivation. However, it conflicts with the Humean theory that motives must be constituted by desires. Simple versions of internalism run into problems with people who do not desire to do what they believe right. This has long been urged by David Brink. Hence, many internalists have adopted more subtle defeasible views, on which only rational agents will have a desire to act. (...) I will argue that more complex versions run into problems with self-effacing values of the sort Parfit highlights in another context. Such values can only be attained indirectly. After proposing a general account of motivation suited to the internalist thesis, I argue that Anti-Humeanism is better suited to accommodating the internalist insight. (shrink)

The vast majority of putative solutions to the liar paradox face the infamous revenge problem. In recent work, however, Kevin Scharp has extensively developed an exciting and highly novel “inconsistency approach” to the paradox that, he claims, does not face revenge. If Scharp is right, then this represents a significant step forward in our attempts to solve the liar paradox. However, in this paper, I raise a revenge problem that faces Scharp's inconsistency approach.

Metaethics is the study of metaphysics, epistemology, the philosophy of mind, and the philosophy of language, insofar as they relate to the subject matter of moral or, more broadly, normative discourse – the subject matter of what is good, bad, right or wrong, just, reasonable, rational, what we must or ought to do, or otherwise. But out of these four ‘core’ areas of philosophy, it is plausibly the philosophy of language that is most central to metaethics – and not simply (...) because ‘metaethics’ was for a long time construed more narrowly as a name for the study of moral language. The philosophy of language is central to metaethics because both the advantages of and the open problems facing different metaethical theories differ sharply over the answers those theories give to central questions in the philosophy of language. In fact, among the open problems over which such theories differ, are included particularly further problems in the philosophy of language. This article briefly surveys a range of broad categories of views in metaethics and both catalogues some of the principal issues faced by each in the philosophy of language, as well as how those arise out of their answers to more basic questions in the philosophy of language. I make no claim to completeness, only to raising a variety of important issues. (shrink)

This is an overview of the main themes and theses of _Reasons First_ for a book symposium, and intended to be read alongside the other contributions to that symposium.

The thesis of underdetermination presents a major obstacle to the epistemological claims of scientific realism. That thesis is regularly assumed in the philosophy of science, but is puzzlingly at odds with the actual history of science, in which empirically adequate theories are thin on the ground. We propose to advance a case for scientific realism which concentrates on the process of scientific reasoning rather than its theoretical products. Developing an account of causal–explanatory inference will make it easier to resist the (...) thesis of underdetermination. For, if we are not restricted to inference to the best explanation only at the level of major theories, we will be able to acknowledge that there is a structure in data sets which imposes serious constraints on possible theoretical alternatives. We describe how Differential Inference, a form of inference based on contrastive explanation, can be used in order to generate causal hypotheses. We then go on to consider how experimental manipulation of differences can be used to achieve Difference Closure, thereby confirming claims of causal efficacy and also eliminating possible confounds. The model of Differential Inference outlined here shows at least one way in which it is possible to ‘reason from the phenomena’. (shrink)
