Epistemic modals are standardly taken to be context-dependent quantifiers over possibilities. Thus sentences containing them get truth-values with respect to both a context and an index. But some insist that this relativization is not relative enough: `might'-claims, they say, only get truth-values with respect to contexts, indices, and—the new wrinkle—points of assessment (hence, CIA). Here we argue against such "relativist" semantics. We begin with a sketch of the motivation for such theories and a generic formulation of them. Then we catalogue (...) central problems that any such theory faces. We end by outlining an alternative story. (shrink)

It is a recurring mantra that epistemic must creates a statement that is weaker than the corresponding flat-footed assertion: It must be raining vs. It’s raining. Contrary to classic discussions of the phenomenon such as by Karttunen, Kratzer, and Veltman, we argue that instead of having a weak semantics, must presupposes the presence of an indirect inference or deduction rather than of a direct observation. This is independent of the strength of the claim being made. Epistemic must is therefore quite (...) similar to evidential markers of indirect evidence known from languages with rich evidential systems. We work towards a formalization of the evidential component, relying on a structured model of information states (analogous to some models used in the belief dynamics literature). We explain why in many contexts, one can perceive a lack of confidence on the part of the speaker who uses must. (shrink)

The simplest story about modals—might, must, possibly, necessary, have to, can, ought to, presumably, likelier, and the rest—is also the canon: modals are context-dependent quantifiers over a domain of possibilities. Different flavors of modality correspond to quantification over different domains of possibilities. Logical modalities quantify over all the possibilities there are, physical modalities over possibilities compatible with the..

way on the information available in the contexts in which they are used, it’s not surprising that there is a minor but growing industry of work in semantics and the philosophy of language concerned with the precise nature of the context-dependency of epistemically modalized sentences. Take, for instance, an epistemic might-claim like..

Counterfactuals are typically thought--given the force of Sobel sequences--to be variably strict conditionals. I go the other way. Sobel sequences and (what I call) Hegel sequences push us to a strict conditional analysis of counterfactuals: counterfactuals amount to some necessity modal scoped over a plain material conditional, just which modal being a function of context. To make this worth saying I need to say just how counterfactuals and context interact. No easy feat, but I have something to say on the (...) matter. (shrink)

What we want to be true about ordinary indicative conditionals seems to be more than we can possibly get: there just seems to be no good way to assign truth-conditions to ordinary indicative conditionals. Some take this argument as reason to make our wantings more modest. Others take it to show that indicative conditionals don't have truth-conditions in the first place. But we have overlooked two possibilities for assigning truth-conditions to indicatives. What's more, those possibilities deliver what we want and (...) turn out to be equivalent.

Moore's paradox pits our intuitions about semantic oddnessagainst the concept of truth-functional consistency. Most solutions tothe problem proceed by explaining away our intuitions. But``consistency'' is a theory-laden concept, having different contours indifferent semantic theories. Truth-functional consistency is appropriateonly if the semantic theory we are using identifies meaning withtruth-conditions. I argue that such a framework is not appropriate whenit comes to analzying epistemic modality. I show that a theory whichaccounts for a wide variety of semantic data about epistemic modals(Update Semantics) buys (...) us a solution to Moore's paradox as a corollary.It turns out that Moorean propositions, when looked at through the lenseof an appropriate semantic theory, are inconsistent after all.

This paper has three main goals. First, to motivate a puzzle about how ignorance-expressing terms like maybe and if interact: they iterate, and when they do they exhibit scopelessness. Second, to argue that there is an ambiguity in our theoretical toolbox, and that exposing that opens the door to a solution to the puzzle. And third, to explore the reach of that solution. Along the way, the paper highlights a number of pleasing properties of two elegant semantic theories, explores some (...) meta-theoretic properties of dynamic notions of meaning, dips its toe into some hazardous waters, and offers characterization theorems for the space of meanings an indicative conditional can have.

In "*Must* ...stay ...strong!" (von Fintel & Gillies 2010) we set out to slay a dragon, or rather what we called The Mantra: that epistemic *must* has a modal force weaker than expected from standard modal logic, that it doesn't entail its prejacent, and that the best explanation for the evidential feel of *must* is a pragmatic explanation. We argued that all three sub-mantras are wrong and offered an explanation according to which *must* is strong, entailing, and the felt indirectness (...) is the product of an evidential presupposition carried by epistemic modals. Mantras being what they are, it is no surprise that each of the sub-mantras have been given new defenses. Here we offer them new problems and update our picture, concluding that *must* is (still) strong. (shrink)

“Any theory of conditionals has consequences for less-than-certain judgements. Something is proposed of the form: If A, B is true iff A*B. If a clear-headed person, free from confusions of a logical, linguistic or referential sort, can be nearly sure that A*B yet far from sure that if A, B, or vice versa, then this is strong evidence against the proposal.” (Edgington 1995/2007).

Chalmers' anti-materialist arguments are an interesting twist on a well-known argument form, and his naturalistic dualism is exciting to contemplate. Nevertheless, we think we can save materialism from the Chalmerian attack. This is what we do in the present paper.

Obligation describing language is hooked up with preference, a relation of what-is-better-than-what. But ordinary situations underdetermine such relations of what-is-better-than-what. Even so, there are plainly true sentences describing our obligations in those situations. This mismatch is trouble-making and getting out of the trouble requires either giving up the easy link between “ought” and preference or re-thinking the kind of things preferences can be.

Sly Pete and Mr. Stone are playing poker on a Mississippi riverboat. It is now up to Pete to call or fold. My henchman Zack sees Stone’s hand, which is quite good, and signals its content to Pete. My henchman Jack sees both hands, and sees that Pete’s hand is rather low, so that Stone’s is the winning hand. At this point, the room is cleared. A few minutes later, Zack slips me a note which says “If Pete called, he (...) won,” and Jack slips me a note which says “If Pete called, he lost”. (shrink)

We must change our beliefs, and change them in particular ways, in response to new information. But not all changes are created equal: some are rational changes, some not. The Problem of Epistemic Change is the problem of specifying the rational constraints on how the epistemic state of an agent ought to change in the face of new information. This dissertation is about the philosophical and logical investigation of rational belief change. I start by arguing that the familiar foundations---coherence distinction (...) from static epistemology does not adequately carve up the logical space of theories of epistemic change. It is better to think of theories as being loosely ordered along a continuum from more to less foundational. The ordering, however, is "clumpy" in the sense that there are large regions in the ordering which remain unexplored. I then present and develop GDEC which is a new foundations model of belief revision that fills a gap in this ordering of theories of epistemic change. The key insight in GDEC is that belief that...is ambiguous between the attitudes of accept that...and expect that... GDEC respects the difference and how it matters for epistemic change. I show that GDEC is a genuine competitor to the AGM theory of belief revision in the sense that the two approaches are incompatible. The remainder of the dissertation is devoted to exploring the logical dynamics of GDEC and the models I develop here which extend it by applying them to a series of richer epistemic environments. I show how puzzles and paradoxes which confound other theories of belief revision are solved in a unified way by GDEC and its extensions. In particular, I give solutions to Moore's Paradox, Fuhrmann's Impossibility Theorem, the Reduction Problem of Epistemic Conditionals, and the Gardenfors Impossibility Theorem. (shrink)

Features of experimental design impose auxiliary hypotheses on experimenters. Hertwig & Ortmann rightly argue that the ways some variables are implemented in psychology cloud results, whereas the different implementations in economics provide for more robust results. However, not all design variables support this general conclusion. The repetition of trials may confuse results depending on what theory is being tested. We explore this in the case of simple bargaining games.

Teaching children to ask and answer questions is critically important if they are to learn to talk and reason effectively together, particularly during inquiry-based science where they are required to investigate topics, consider alternative propositions and hypotheses, and problem-solve together to propose answers, explanations, and prediction to problems at hand. This study involved 108 students (53 boys and 55 girls) from seven, Year 7 teachers’ classrooms in five primary schools in Brisbane, Australia. Teachers were randomly allocated by school to one (...) of two conditions: the metacognitive questioning condition (Trained condition) or the prescriptive questioning condition (Untrained condition). Data on students’ discourse and reasoning and problem-solving (RP-S) were collected across Times 1 and 2. The results showed that while there were significant differences in the discourse categories of the students in the two conditions at Time 1, the only significant difference was in questioning behaviour at Time 2 with the students in the trained condition continuing to ask more questions than their untrained peers. Given that these students had been taught to specifically ask ‘thinking’ questions that probed and interrogated information, these results are not surprising. A follow-up examination of students’ discourse during their small group discussions illustrated how these students interacted with each other to probe and interrogate information by providing explanations and reasons to make their thinking explicit and by using analogies to verbally represent concepts they were trying to express. Results on the follow-up reasoning and problem-solving (RP-S) tasks indicated that students in the Trained and Untrained conditions improved their scores from Time 1 to Time 2 although the change was not significantly different between conditions.

Background There is little dispute that the ideal moral standard for surgical informed consent calls for surgeons to carry out a disclosure dialogue with patients before they sign the informed consent form. This narrative study is the first to link patient experiences regarding the disclosure dialogue with patient-surgeon trust, central to effective recuperation and higher adherence. Methods Informants were 12 Israelis, aged 29–81, who underwent life-saving surgeries. A snowball sampling was used to locate participants in their initial recovery process upon (...) discharge. Results Our empirical evidence indicates an infringement of patients’ right to receive an adequate disclosure dialogue that respects their autonomy. More than half of the participants signed the informed consent form with no disclosure dialogue, and thus felt anxious, deceived and lost their trust in surgeons. Surgeons nullified the meaning of informed consent rather than promoted participants’ moral agency and dignity. Discussion Similarity among jarring experiences of participants led us to contend that the conduct of nullifying surgical informed consent does not stem solely from constraints of time and resources, but may reflect an underlying paradox preserving this conduct and leading to objectification of patients and persisting in paternalism. We propose a multi-phase data-driven model for informed consent that attends to patients needs and facilitates patient trust in surgeons. Conclusions Patient experiences attest to the infringement of a patient’s right to respect for autonomy. In order to meet the prima facie right of respect for autonomy, moral agency and dignity, physicians ought to respect patient’s needs. It is now time to renew efforts to avoid negligent disclosure and implement a patient-centered model of informed consent. (shrink)

Social revolutions--that is critical periods of decisive, qualitative change--are a commonly acknowledged historical fact. But can the idea of revolutionary upheaval be extended to the world of ideas and theoretical debate? The publication of Kuhn's The Structure of Scientific Revolutions in 1962 led to an exciting discussion of revolutions in the natural sciences. A fascinating, but little known, off-shoot of this was a debate which began in the United States in the mid-1970's as to whether the concept of revolution could (...) be applied to mathematics as well as science. Michael Grove declared that revolutions never occur in mathematics, while Joseph Dauben argued that there have been mathematical revolutions and gave some examples. This book is the first comprehensive examination of the question. It reprints the original papers of Grove, Dauben, and Mehrtens, together with additional chapters giving their current views. To this are added new contributions from nine further experts in the history of mathematics, who each discuss an important episode and consider whether it was a revolution. The whole question of mathematical revolutions is thus examined comprehensively and from a variety of perspectives. This thought-provoking volume will interest mathematicians, philosophers, and historians alike. (shrink)

Within medical education, there is an increasing need to provide ethics education for learners embarking on service learning. The concept of hospitality, as illustrated in Homer’s classic epic the Odyssey, has the potential to underpin such ethics education. This paper describes the implementation and evaluation of an ethics education session for medical students, built on the concept of hospitality, before they embark on a three-year longitudinal service-learning home visit program. In preparation for their household visits, second-year students at a medical (...) school in Miami, Florida, participate in weekly didactic sessions. One of these classes consisted of a two-hour ethics session, involving a brief introductory large-group lecture, followed by self-administered small-group discussions of a series of case scenarios. An innovative web-based platform called Rise allowed the students to run their own small group activities. To assess the impact on the students’ ability to identify, and on their confidence in handling, ethical dilemmas, we administered pre- and post-session surveys. Students indicated statistically significant improvement in median responses to all questions, for two consecutive years. Students also listed three adjectives, both before and after the session, that they associated with good and bad hosts and guests. The consistency of the terms listed suggests that hospitality is a robust concept for the learners. In our experience, the concept of hospitality provides a robust framework for the students, and the mixed large-group and self-facilitated small-group format offers a valuable tool for ethics education related to service learning in medicine. Our study supports the utility of the concept as a teaching tool, and the format facilitates a session using minimal faculty. The notion of hospitality seems particularly fruitful for various ethical considerations in medicine, even beyond those that involve home visits. (shrink)

The aim of this article is to explore what the concept of interdisciplinarity can bring to our developing understanding of education as a field of enquiry. We shall draw upon some recent writing on the disciplines of education in order to explore the potentially negative consequences of the way in which the disciplines are institutionalised and territorialised. We also assign some prominence to a personal account of an eminent anthropologist's perambulations through a disciplinary landscape in order to put forward an (...) initial, tentative view of interdisciplinary endeavour. Nietzsche's essay 'Schopenhauer as educator' and the distinction between measurable time (chronos) and lived time (kairos) are the vehicles through which the authors explore the nature of intellectual inquiry. They also consider the implications of the prevalence of spatial and cartographic metaphors in scholarship in this area of enquiry, and reflect on the contrasting notions of habitation and occupation. They put forward the view that the key to understanding the role of the disciplines of education is in exploring the reciprocal relations between the lives of academics and the institutions of the disciplines (books, articles, reports, societies, journals, conferences, networks), between personal narrative and grand narrative, and in attempting to reconcile full-bodied being and the ghostly life of 'pure knowledge'.

This reissue of D. A. Gillies highly influential work, first published in 1973, is a philosophical theory of probability which seeks to develop von Mises’ views on the subject. In agreement with von Mises, the author regards probability theory as a mathematical science like mechanics or electrodynamics, and probability as an objective, measurable concept like force, mass or charge. On the other hand, Dr Gillies rejects von Mises’ definition of probability in terms of limiting frequency and claims that probability should (...) be taken as a primitive or undefined term in accordance with modern axiomatic approaches. This of course raises the problem of how the abstract calculus of probability should be connected with the ‘actual world of experiments’. It is suggested that this link should be established, not by a definition of probability, but by an application of Popper’s concept of falsifiability. In addition to formulating his own interesting theory, Dr Gillies gives a detailed criticism of the generally accepted Neyman Pearson theory of testing, as well as of alternative philosophical approaches to probability theory. The reissue will be of interest both to philosophers with no previous knowledge of probability theory and to mathematicians interested in the foundations of probability theory and statistics.

Semmelweis’s investigations of puerperal fever are some of the most interesting in the history of medicine. This paper considers Hempel’s analysis of the Semmelweis case. It argues that this analysis is inadequate and needs to be supplemented by some Kuhnian ideas. Kuhn’s notion of paradigm needs to be modified to apply to medicine in order to take account of the classification schemes involved in medical theorising. However with a suitable modification it provides an explanation of Semmelweis’s failure which is argued (...) to be superior to some of the external reasons often given. Despite this success in applying Kuhn’s ideas to medicine, it is argued that these ideas must be further modified to take account of the fact that medicine is not a natural science but primarily a practice designed to prevent and cure diseases.

In their 1983 article, Popper and Miller present an argument against inductive probability. This argument is criticized by Redhead in his 1985 article. The aim of the present note is to state one form of the Popper-Miller argument, and defend it against Redhead's criticisms.

Galavotti begins her book by stressing the centrality of probability to a whole range of philosophical problems. She writes 1: "Probability invests all branches of philosophical investigation, from epistemology to moral and political philosophy, and impinges upon major controversies, like that between determinism and indeterminism, or between free will and moral obligation, and problems such as: ‘What degree of certainty can human knowledge attain?’ ‘What is the relationship between probability and certainty?’" She then explains that her book will focus on (...) the interpretation of the notion of probability. Chapter 1 contains some general remarks about the notion of probability, and Chapter 2 presents a brief introduction to the formal calculus of probability. Then in the next five chapters Galavotti presents in turn the five main interpretations of probability, namely the classical, frequency, propensity, logical, and subjective.Galavotti's approach to the material is historical. She traces, through extensive quotations from, and discussions of, the principal authors, the development of each of the interpretations. In many cases, she deals with early advocates of the position who are often omitted, such as De Morgan, Boole, and Jevons in the case of the logical interpretation, and Donkin in the case of the subjective interpretation. At the same time, the story is often brought right up to the present with discussions of recent authors such as Richard Jeffrey and Patrick Suppes in the case of the subjective interpretation. Galavotti's book is an excellent advertisement for the virtues of …. (shrink)

The paper begins with a discussion of Russell's view that the notion of cause is unnecessary for science and can therefore be eliminated. It is argued that this is true for theoretical physics but untrue for medicine, where the notion of cause plays a central role. Medical theories are closely connected with practical action (attempts to cure and prevent disease), whereas theoretical physics is more remote from applications. This suggests the view that causal laws are appropriate in a context where (...) there is a close connection to action. This leads to a development of an action-related theory of causality which is similar to the agency theory of Menzies and Price, but differs from it in a number of respects, one of which is the following. Menzies and Price connect ‘A causes B’ with an action to produce B by instantiating A, but, particularly in the case of medicine, the law can also be linked to the action of trying to avoid B by ensuring that A is not instantiated. The action-related theory has in common with the agency theory of Menzies and Price the ability to explain causal asymmetry in a simple fashion, but the introduction of avoidance actions together with some ideas taken from Russell enable some of the objections to agency accounts of causality to be met. Introduction Russell on causality Preliminary exposition of the action-related theory Differences between the action-related theory and the agency theory of Menzies and Price Explanation of causal asymmetry Objections to the action-related theory Extension of the theory to the indeterminate case.

This paper takes up a suggestion made by Floridi that the digital revolution is bringing about a profound change in our metaphysics. The paper aims to bring some older views from philosophy of mathematics to bear on this problem. The older views are concerned principally with mathematical realism—that is the claim that mathematical entities such as numbers exist. The new context for the discussion is informational realism, where the problem shifts to the question of the reality of information. Mathematical realism (...) is perhaps a special case of informational realism. The older views concerned with mathematical realism are the various theories of World 3. The concept of World 3 was introduced by Frege, whose position was close to Plato’s original views. Popper developed the theory of World 3 in a different direction which is characterised as ‘constructive Platonism’. But how is World 3 constructed? This is explored by means of two analogies: the analogy with money, and the analogy with meaning, as explicated by the later Wittgenstein. This leads to the development of an account of informational realism as constructive Aristoteliansim. Finally, this version of informational realism is compared with the informational structural realism which Floridi develops in his 2008 and 2009 papers in Synthese. Similarities and differences between the two positions are noted. (shrink)

The aim of this paper is to consider whether critical rationalism has any ideas which could usefully be applied to the internet. Today we tend to take the internet for granted and it is easy to forget that it was only about two decades ago that it began to be used to any significant extent. Accordingly in section 1 of the paper, there is a brief consideration of the history of the internet. At first sight this makes it looks implausible (...) that any of Popper’s ideas could be applicable to the internet, since Popper died before the internet came into general use. However, section 2 argues that Popper’s theory of World 3 does apply very well to the internet. This application is significant because, as shown in section 3, it leads to the problem of misinformation, which is one of the most significant problems generated by the internet. In section 4 there is an attempt to solve this problem using ideas taken from Popper’s epistemology. It is argued that there should be changes in education designed to prepare students for the internet age. Teaching in the internet age should focus on presenting to the students not just the accepted theories but also the evidence on which they are based. An illustration of how this might be done is given by considering an example from science teaching, namely the teaching of Newtonian mechanics in the last years of school or first years of university.

Teaching students to ask and answer questions is critically important if they are to engage in reasoned argumentation, problem-solving, and learning. This study involved 35 groups of grade 6 children from 18 classrooms in three conditions (cognitive questioning condition, community of inquiry condition, and the comparison condition) who were videotaped as they worked on specific inquiry-based science tasks. The study also involved the teachers in these classrooms who were audio-taped as they interacted with the children during these tasks. The results (...) show that while there were no significant differences in the children's explanatory behaviour across the two time periods, there were significant differences in the total verbal interactions between the children in the cognitive questioning condition and their peers in the community of inquiry and comparison conditions. Furthermore, the children in the cognitive questioning condition obtained higher reasoning and problem-solving scores than peers in the other conditions. Interestingly, while there were no significant differences between the teachers’ basic and extended mediating behaviours in the three conditions at Times 1 and 2, there was a significant difference in extended mediation behaviours with the teachers demonstrating nearly three times more extended mediation to promote students’ learning at Time 2 than they did at Time 1. Teacher intervention in providing guidance in how to interact during cooperative, inquiry-based science appears to be critical to helping students engage in higher-level thinking and learning.

The paper begins with an exposition of Aristotle’s own philosophy of mathematics. It is claimed that this is based on two postulates. The first is the embodiment postulate, which states that mathematical objects exist not in a separate world, but embodied in the material world. The second is that infinity is always potential and never actual. It is argued that Aristotle’s philosophy gave an adequate account of ancient Greek mathematics; but that his second postulate does not apply to modern mathematics, (...) which assumes the existence of the actual infinite. However, it is claimed that the embodiment postulate does still hold in contemporary mathematics, and this is argued in detail by considering the natural numbers and the sets of ZFC. (shrink)
