1. Causal knowledge is an indispensable element in science. Causal assertions are embedded in both the results and the procedures of scientific investigation. 2. It is therefore worthwhile to investigate the meaning of causal statements and the ways in which we can arrive at causal knowledge.

On Kratzer’s canonical account, modal expressions (like “might” and “must”) are represented semantically as quantifiers over possibilities. Such expressions are themselves neutral; they make a single contribution to determining the propositions expressed across a wide range of uses. What modulates the modality of the proposition expressed—as bouletic, epistemic, deontic, etc.—is context.2 This ain’t the canon for nothing. Its power lies in its ability to figure in a simple and highly unified explanation of a fairly wide range of language use. Recently, (...) though, the canon’s neat story has come under attack. The challenge cases involve the epistemic use of a modal sentence for which no single resolution of the contextual parameter appears capable of accommodating all our intuitions.3 According to these revisionaries, such cases show that the canonical story needs to be amended in some way that makes multiple bodies of information relevant to the assessment of such statements. Here I show that how the right canonical, flexibly contextualist account of modals can accommodate the full range of challenge cases. The key will be to extend Kratzer’s formal semantic account with an account of how context selects values for a modal’s.. (shrink)

Autobiographical memories typically give rise either to memory reports (“I remember going swimming”) or to first person past-tense judgements (“I went swimming”). This article focuses on first person past-tense judgements that are (epistemically) based on autobiographical memories. Some of these judgements have the IEM property of being immune to error through misidentification. This article offers an account of when and why first person past-tense judgements have the IEM property.

The idea of a 'logic of quantum mechanics' or quantum logic was originally suggested by Birkhoff and von Neumann in their pioneering paper [1936]. Since that time there has been much argument about whether, or in what sense, quantum 'logic' can be actually considered a true logic (see, e.g. Bell and Hallett [1982], Dummett [1976], Gardner [1971]) and, if so, how it is to be distinguished from classical logic. In this paper I put forward a simple and natural semantical framework (...) for quantum logic which reveals its difference from classical logic in a strikingly intuitive way, viz. through the fact that quantum logic admits (suitably formulated versions of) the characteristic quantum-mechanical notions of superposition and incompatibility of attributes. That is, precisely the features that distinguish quantum from classical physics also serve, within this framework, to distinguish quantum from classical logic. Some light is shed on the question of whether quantum logic is a genuine logical system by introducing a natural entailment relation for quantum-logical formulas with the implication symbol. The novelty is that, although implication behaves as it should (i.e. the 'deduction theorem' holds), the order of introduction of premises is significant. The fact that a reasonable entailment relation can be formulated for quantum logic supports the view that it is a genuine logical system and not merely an algebraic formalism. (shrink)

As the usual regulatory framework did not fit well during the last Ebola outbreak, innovative thinking still needed. In the absence of an outbreak, randomised controlled trials of clinical efficacy in humans cannot be done, while during an outbreak such trials will continue to face significant practical, philosophical, and ethical challenges. This article argues that researchers should also test the safety and effectiveness of novel vaccines in wild apes by employing a pluralistic approach to evidence. There are three reasons to (...) test vaccines in wild populations of apes: i) protect apes; ii) reduce Ebola transmission from wild animals to humans; and iii) accelerate vaccine development and licensing for humans. Data obtained from studies of vaccines among wild apes and chimpanzees may even be considered sufficient for licensing new vaccines for humans. This strategy will serve to benefit both wild apes and humans. (shrink)

Most ethics committees which review research protocols insist that potential research participants reserve unconditional or absolute ‘right’ of withdrawal at any time and without giving any reason. In this paper, I examine what consent means for research participation and a sense of commitment in relation to this right to withdraw. I suggest that, once consent has been given (and here I am excluding incompetent minors and adults), participants should not necessarily have unconditional or absolute rights to withdraw.This does not imply (...) that that there should be a complete absence of rights, or, indeed, an abandonment of the right to withdraw. The point of this paper is to show that the supposed unconditional or absolute nature of these rights may be self‐defeating and so fail to respect the autonomy of participants. In addition, and on a more positive note, I suggest that, attaching certain conditions on the right to withdraw, may better respect the autonomy of these participants by underlining the idea that autonomy is more than mere whim or indifference to the fate of others. On the contrary, research staff are currently unable to ‘push’ participants, who may merely have logistical difficulties unrelated to the research itself, but who really want to stay the course, for fear of coercing them. Furthermore, researchers now try to ‘screen out’ people they think may be unreliable to protect the science of the study and so groups at risk of dropping out may be unfairly denied access to research treatments. I conclude that on‐going negotiation between the relevant parties could be on balance the only truly acceptable way forward but concede certain important limitations to take into account. (shrink)

We offer a critical survey of the most discussed accounts of epistemic peer disagreement that are found in the recent literature. We also sketch an alternative approach in line with a pluralist understanding of epistemic rationality.

This is the first in a series of five papers on the role, remit and function of research ethics committees which are intended to provide for REC members a broad understanding of the most important issues in research ethics and governance. The first considers the rationale for having ethics review by committee at all; seeking to explain why ethics committees, as we currently have them, are so important to the wider system of governing research.

Alfandre et al. helpfully outlines the case for attending to contingency planning as well as to crisis measures during a pandemic. The authors provides a helpful framework for reflecting on...

In this paper we study the variety of order Hilbert algebras, which is the equivalent algebraic semantics of the order implicational calculus of Bull.

Questions of religious liberty have become flashpoints of controversy in virtually every area of life around the world. Despite protection of religious liberty at both supranational and individual state levels, there is an increasing number of conflicts concerning the proper way to recognize it, both in modern secular states, and in countries with an established religion or theocratic mode of government. This book provides an analysis of the general concept of religious liberty with a close study of important cases that (...) serve as a test bed for proposals. It combines the insights of both pure academics and experienced practitioners in law to take a fresh look at the nature, scope and limits of religious liberty. Divided into two parts, the collection presents a blend of legal and philosophical approaches, and draws on cases from a wide range of jurisdictions, including Brazil, India, Australia, USA, Netherlands, and Canada. Presenting a broad range of views, this often provocative volume makes fascinating reading for academics and researchers working in the areas of law and religion, legal philosophy and human rights.

This is the second in a series of five papers on the role, remit and function of research ethics committees which are intended to provide for REC members a broad understanding of the most important issues in research ethics and governance. This paper examines the role of ethics committees in assessing the science of the research it reviews. While ethics committees are not specifically constituted to review the science of a project, they must nevertheless assess the social benefits of research (...) and, in this context, have an important role in checking that the science has been properly peer-reviewed.

In a previous essay we demonstrated that quantum mechanical formalism is incompatible with some necessary principles of the mechanism conception still dominant in the physicist’s community. In this paper we show, based on recent empirical evidence in quantum physics, the inevitability of abandoning the old mechanism conception and to construct a new one in which physical reality is seen as a representation which refers to relations established through operations made by us in a world that we are determining. This change (...) is profound and radical, with immediate consequences on both Ontology and Epistemology. This work is our contribution to try to make more concrete how this new conception of the world might be. (shrink)

Behrendt & Young (B&Y) propose an explanation for schizophrenia in terms of a cortical default in the interaction between consciousness and cognition. However, schizophrenia more likely involves miscommunication between subcortical and cortical affective circuits in the brain, a default in the interaction between consciousness and emotion. The typical “affective” nature of hallucinations in schizophrenia provides compelling evidence for subcortical involvement.

In this article, we query binaries of mobility and immobility in language studies via an empirical focus on language/social practices in a site that bridges the global North and global South. To do so, we work from a Southern praxis perspective to analyze discourses/knowledges informing the performance of accounts from Cambodian men, interviewed about transactional same-sex relationship practices between (ostensibly immobile) local men and (ostensibly mobile) male tourists to Cambodia from the global North. The analysis focuses on a process in (...) which participants’ chronotopic awareness of language shapes a negotiation of power, knowledge, and action with respect to these relationships. Encompassing the discursive positioning of selves and others through the deployment of relevant and affective chronotopes, the talk from these Cambodian men allows us to challenge assumptions about (im)mobility, awareness, agency, sexuality, and power, and demonstrate how these are accessed in multiple ways at this site of North/South contact.

A reconstruction based on previously unpublished notes, of Austin’s views of the Line and Cave allegories in Plato’s Republic. In these drafts, Austin discusses the prominent issues that arise in the context of Plato’s Line allegory, e.g. the questions of division and continuity, and shows how the different stages in the Cave allegory correspond to individual sections of the Line.

Unlike nonhuman primates, thousands of bird species have articulatory capabilities that equal or surpass those of humans, and they develop their vocalizations through vocal imitation in a way that is very similar to how human infants learn to speak. An understanding of how speech mechanisms have evolved is therefore unlikely to yield key insights into how the human brain is special.

Mackie attempts to revise Locke's theory of the identity of persons. Locke's equation of personal identity with the unity of consciousness is set out. Mackie examines various objections to Locke's theory and his use of puzzle cases is highlighted. Recent theories of personal identity, such as Parfit's, are critically discussed. Mackie suggests that the equation of personal identity with the continuity of neurophysiological structure would resolve some of the difficulties associated with an account of personal identity.

This chapter considers both Locke's theory of substance and Berkeley's subsequent criticisms of it. Mackie discusses the difference between real essence and nominal essence. He argues that Locke should have equated substance with real essence and rejected the notion of substance as substratum. Mackie also argues that Locke invokes a theory of the use of language that anticipates the theory of natural kinds put forward by Kripke.

In this paper I distinguish two levels of intellectual importance, derived and underived, showing how the former can be species-based. Then I do four things: first, identify a neglected way, stemming from perceived human intellectual maturity, in which many of us are vulnerable to a sense of species-based importance; second, show—in part by appealing to facts about deep time—that we have no right to this sense and so evince a failure of intellectual humility if we acquiesce in it; third, defend (...) the view that the claims of intellectual humility on those who would be overall rational are not in this regard overridden; and then, finally, gesture at some of the consequences of this result for inquiry.

A cross-sectional study to ascertain what the Singapore population would regard as material risk in the anaesthesia consent-taking process and identify demographic factors that predict patient preferences in medical decision-making to tailor a more patient-centered informed consent. A survey was performed involving patients 21 years old and above who attended the pre-operative evaluation clinic over a 1-month period in Singapore General Hospital. Questionnaires were administered to assess patients’ perception of material risks, by trained interviewers. Patients’ demographics were obtained. Mann–Whitney U (...) test and Kruskal-Wallis one-way analysis of variance was used. Statistical significance was taken at p < 0.05. Four hundred fourteen patients were eligible of which 26 refused to participate and 24 were excluded due to language barrier. 364 patients were recruited. A higher level of education, being employed and younger age group are factors identified in patients who wanted greater participation in medical decisions. Gender, marital status, type of surgery, and previous surgical history did not affect their level of participation. The complications most patients knew about were Nausea, Drowsiness and Surgical Wound Pain. Patients ranked Heart Attack, Death and Stroke as the most significant risks that they wanted to be informed about in greater detail. Most patients wanted to make a joint decision with the anaesthetist, instead of letting the doctor decide or deciding for themselves. Discussion with the anaesthetist is the preferred medium of communication compared to reading a pamphlet or watching a video. Age and educational level can influence medical decision-making. Despite the digital age, most patients still prefer a clinic consult instead of audio-visual multimedia for pre-operative anaesthetic counselling. The local population appears to place greater importance on rare but serious complications compared to common complications. This illustrates the need to contextualize information provided during informed consent to strengthen the doctor-patient relationship. (shrink)
