John Hardwig has championed the thesis (NE) that evidence that an expert EXP has evidence for a proposition P, constituted by EXP’s testimony that P, is not evidence for P itself, where evidence for P is generally characterized as anything that counts towards establishing the truth of P. In this paper, I first show that (NE) yields tensions within Hardwig’s overall view of epistemic reliance on experts and makes it imply unpalatable consequences. Then, I use Shogenji-Roche’s theorem of transitivity (...) of incremental confirmation to show that (NE) is false if a natural Bayesian formalization of the above notion of evidence is implemented. I concede that Hardwig could resist my Bayesian objection if he re-interpreted (NE) as a more precise thesis that only applies to community-focused evidence. I argue, however, that this precisification, while diminishing the philosophical relevance of (NE), wouldn’t settle the tensions internal to Hardwig’s views. (shrink)

All extant purely probabilistic measures of explanatory power satisfy the following technical condition: if Pr(E | H1) > Pr(E | H2) and Pr(E | ∼H1) < Pr(E | ∼H2), then H1’s explanatory power with respect to E is greater than H2’s explanatory power with respect to E. We argue that any measure satisfying this condition faces three serious problems—the Problem of Temporal Shallowness, the Problem of Negative Causal Interactions, and the Problem of Nonexplanations. We further argue that many such measures (...) face a fourth problem—the Problem of Explanatory Irrelevance. (shrink)

This paper proposes a new interpretation of mutual information (MI). We examine three extant interpretations of MI by reduction in doubt, by reduction in uncertainty, and by divergence. We argue that the first two are inconsistent with the epistemic value of information (EVI) assumed in many applications of MI: the greater is the amount of information we acquire, the better is our epistemic position, other things being equal. The third interpretation is consistent with EVI, but it is faced with the (...) problem of measure sensitivity and fails to justify the use of MI in giving definitive answers to questions of information. We propose a fourth interpretation of MI by reduction in expected inaccuracy, where inaccuracy is measured by a strictly proper monotonic scoring rule. It is shown that the answers to questions of information given by MI are definitive whenever this interpretation is appropriate, and that it is appropriate in a wide range of applications with epistemic implications.

Background Payment of research participants helps to increase recruitment for research studies, but can pose ethical dilemmas. Research ethics committees (RECs) have a centrally important role in guiding this practice, but standardisation of the ethical approval process in Ireland is lacking. Aim Our aim was to examine REC policies, experiences and concerns with respect to the payment of participants in research projects in Ireland. Method Postal survey of all RECs in Ireland. Results Response rate was 62.5% (n=50). 80% of RECs (...) reported not to have any established policy on the payment of research subjects while 20% had refused ethics approval to studies because the investigators proposed to pay research participants. The most commonly cited concerns were the potential for inducement and undermining of voluntary consent. Conclusions There is considerable variability among RECs on the payment of research participants and a lack of clear consensus guidelines on the subject. The development of standardised guidelines on the payment of research subjects may enhance recruitment of research participants. (shrink)

The disjunction problem and the distality problem each presents a challenge that any theory of mental content must address. Here we consider their bearing on purely probabilistic causal theories. In addition to considering these problems separately, we consider a third challenge—that a theory must solve both. We call this “the hard problem.” We consider 8 basic ppc theories along with 240 hybrids of them, and show that some can handle the disjunction problem and some can handle the distality problem, but (...) none can handle the hard problem. This is our main result. We then discuss three possible responses to that result, and argue that though the first two fail, the third has some promise. (shrink)

Ovid completes his narrative of the origin of Croton with the following lines (Met. 15.58–9):talia constabat certa primordia famaesse loci positaeque Italis in finibus urbis.It was agreed by sure fame that such were the beginningsof the place and of the city established within Italian borders.

I argue elsewhere (Roche 2014) that evidence of evidence is evidence under screening-off. Tal and Comesaña (2017) argue that my appeal to screening-off is subject to two objections. They then propose an evidence of evidence thesis involving the notion of a defeater. There is much to learn from their very careful discussion. I argue, though, that their objections fail and that their evidence of evidence thesis is open to counterexample.

This article explores the patient consent process in modern community pharmacy practice and discusses the related ethical dilemmas in this environment. The myth of appropriately informed consent, and irrefutable evidence as to a pharmacist’s intentions when advising a patient, are core issues for discussion. The objective is to clarify where such dilemmas may exist in the consent process and to ultimately form a framework against which ethical guidelines might facilitate resolution of the dilemma faced by the pharmacist who is expected (...) to simultaneously maintain legal and duty of care responsibilities in the patient consent process.

Is there some general reason to expect organisms that have beliefs to have false beliefs? And after you observe that an organism occasionally occupies a given neural state that you think encodes a perceptual belief, how do you evaluate hypotheses about the semantic content that that state has, where some of those hypotheses attribute beliefs that are sometimes false while others attribute beliefs that are always true? To address the first of these questions, we discuss evolution by natural selection and (...) show how organisms that are risk-prone in the beliefs they form can be fitter than organisms that are risk-free. To address the second question, we discuss a problem that is widely recognized in statistics – the problem of over-fitting – and one influential device for addressing that problem, the Akaike Information Criterion (AIC). We then use AIC to solve epistemological versions of the disjunction and distality problems, which are two key problems concerning what it is for a belief state to have one semantic content rather than another.

This article is a reflection on the relation between two currents of classical philosophy, postkantian idealism and cartesian spiritualism, as they are found in the work of J. Lachelier. It studies why it was expected that postkantian idealism would bring strong evidence in support of the spiritualist affirmations, even though the kantian critique placed the method that traditionaly justified those affirmations in a state of crisis, and even though ideas as important as those of an afterlife and of a transcendant (...) God where excluded from this new system and taken over by religious belief. However, the analysis of the concept of idealism invites us to think that, even as beliefs, such ideas will always remain redhibitory for a system that begins with the negation of anything beyond thought.

This essay addresses the need for a new model of corporation, one which has corporations responsible for the environment in which they operate, and for nurturing all human beings who come into contact with them, and able to deliver sufficient returns to their investors. The main thesis is that the current paradigm of corporations, their model of governance, and their most fundamental priorities and objectives drives them into the selfish pursuit of profits at the expense of environmental and societal concerns, (...) respect for people, and equitable distribution of wealth. With the advent of a free market economy in Hungary, there is an extraordinary opportunity to invent a corporate model, free of western history, yet informed by it. This is a time when it is critical to resist the pull to adopt the prevailing model of the western world, and to begin the invention of a new model in which concern for profits and growth is held on an equal footing with concern for people, for equity, for values being lived, such that the interests of all humankind and our environment are taken care of. This essays postulates what the new measures of corporate performance would need to be and examines the new accountabilities of managers and leaders that would follow. (shrink)

This article examines the theory of personality compatible with Marxism developed by the French Marxist philosopher Lucien Sève, examines his view of how a Marxist biography should be written and how actual biographies should be evaluated. The conclusion is that Marxist biography should be distinctive, and that Sève has presented a plausible sketch of what a Marxist biography should look like. But he has also laid down an incredibly difficult set of criteria for success in which even Marxists themselves fail (...) to satisfy in their biographical writing, and perhaps unsurprisingly no one does, or perhaps could ever, fulfil all the criteria of such a biography, however potentially worthwhile the effort.

Douglas and Ellis suggest that institutionally universities and schools are required to work with different conceptual tool-kits. Seeking to minimise the potential standoff between academic and practitioner knowledge, and, therefore, to enhance the learning of student teachers, means, they suggest, rethinking both the social relationships and the processes of abstracting knowledge from experience. Lingard and Renshaw advocate that all education practitioners, policy makers and teachers, should have a researcherly disposition, be interested in research and knowledge production and see themselves as (...) participants in the field of educational research broadly defined.

"Roger Garaudy was for many years at the centre of the French Communist Party but was eventually expelled for his liberal views. In the Seventies he developed a project to bring Marxism and Christianity together, to include all humanity in a project to set all people free. What emerges from Garaudy's project is a very modern Marxism, with its emphasis on the individual, its ecological politics, and in its insistence on religion as central to human emancipation. Although Garaudy himself became (...) frustrated by the West and converted to Islam in 1982, ending his life discredited in the West, it is certainly possible that Garaudy's project represents a good, perhaps even the best, starting point for Marxism in today's world"--.

This book, first published in 1974, studies the similarities between Rousseau's thought and that of the Stoics, examining Rousseau's ideas on man, society, the state and government. It makes close reference to Rousseau's writings, and to the works of Seneca and other Stoics, presenting an opportunity to really come to grips with a complex and often contradictory mind.

Lucien Sève devoted his life to the development of a Marxist theory of the personality. In so doing, and as part of a theoretical debate with both Marxist humanists and structural Marxists within the Parti Communiste Français, he was inevitably drawn to analyse alienation as a category of Marxist analysis. His conclusion was that although Althusser had been right to argue for the ‘epistemological break’ in Marx’s thought, it was wrong to suggest that Marx abandoned the concept of alienation in (...) his later work. Far from it: a transformed conception of alienation derived from historical materialism remains the key to understanding Marxism. (shrink)

This paper analyzes court rulings on tissue samples as property and critiques objections that have been raised to the recognition of DNA samples as personal property. The cases are: Moore v. Regents of the University of California (1988, 1990), Greenberg v. Miami Children’s Research Institute (2003), and Washington University v.Catalona (2007). The paper argues that it is possible for the law to support both individual privacy and property rights in DNA, recognizing nevertheless that some unresolved questions remain, including what exercising (...) those rights means on a practical level. Finally, it offers suggestions for changes in law based on those considerations. (shrink)

Jean-Paul Sartre pointed to the ‘gap’ in Marxism where a theory of the individual should be. Three attempts to fill it vied in the context of an intense ideological debate within the Parti Communiste Français (PCF) which still resonates today. On the one hand, Louis Althusser’s denial of individual agency as traditionally understood, structuralist theory which proved difficult to apprehend, let alone apply, in a capitalist world. On the other, Roger Garaudy’s Marxist humanist explanation of personality, most likely unsatisfactory for (...) many Marxists on account of its spiritualistic leanings. Finally, Lucien Sève’s approach: very preliminary, often awkwardly formulated, and diluted over time, but a real alternative to structural Marxism and perhaps, in its final diluted form, not incompatible with a humanist approach after all. If the debate could be settled in his favour, the detailed practical work of applying the theory to psychology and other social sciences should take over with some urgency from here. (shrink)

Translation of Aristotle's Physics I-II into Portuguese, with commentaries. Tradução para o português dos livros I e II da Física de Aristóteles, com comentários.

We argue in Roche and Sober (2013) that explanatoriness is evidentially irrelevant in that Pr(H | O&EXPL) = Pr(H | O), where H is a hypothesis, O is an observation, and EXPL is the proposition that if H and O were true, then H would explain O. This is a “screening-off” thesis. Here we clarify that thesis, reply to criticisms advanced by Lange (2017), consider alternative formulations of Inference to the Best Explanation, discuss a strengthened screening-off thesis, and consider (...) how it bears on the claim that unification is evidentially relevant.

We argued that explanatoriness is evidentially irrelevant in the following sense: Let H be a hypothesis, O an observation, and E the proposition that H would explain O if H and O were true. Then our claim is that Pr = Pr. We defended this screening-off thesis by discussing an example concerning smoking and cancer. Climenhaga argues that SOT is mistaken because it delivers the wrong verdict about a slightly different smoking-and-cancer case. He also considers a variant of SOT, called (...) “SOT*”, and contends that it too gives the wrong result. We here reply to Climenhaga’s arguments and suggest that SOT provides a criticism of the widely held theory of inference called “inference to the best explanation”. (shrink)

This book uses mathematical models of language to explain why there are certain gaps in language: things that we might expect to be able to say but can't. For instance, why can we say I ran for five minutes but not *I ran to the store for five minutes? Why is five pounds of books acceptable, but *five pounds of book not acceptable? What prevents us from saying *sixty degrees of water to express the temperature of the water in a (...) swimming pool when sixty inches of water can express its depth? And why can we not say *all the ants in my kitchen are numerous? The constraints on these constructions involve concepts that are generally studied separately: aspect, plural and mass reference, measurement, and distributivity. In this book, Lucas Champollion provides a unified perspective on these domains, connects them formally within the framework of algebraic semantics and mereology, and uses this connection to transfer insights across unrelated bodies of literature and formulate a single constraint that explains each of the judgments above.

In this article, Lucas maintains the falseness of Mechanism - the attempt to explain minds as machines - by means of Incompleteness Theorem of Gödel. Gödel’s theorem shows that in any system consistent and adequate for simple arithmetic there are formulae which cannot be proved in the system but that human minds can recognize as true; Lucas points out in his turn that Gödel’s theorem applies to machines because a machine is the concrete instantiation of a formal system: (...) therefore, for every machine consistent and able of doing simple arithmetic, there is a formula that it can’t produce as true but that we can see to be true, and so human minds and machines have to be different. Lucas considers as well in this article some possible objections to his argument: for any Gödelian formula we could, for instance, construct a machine able to produce it or we could put the Gödelian formulae that we had proved as axioms of a further machine. However - as Lucas underlines - for every of such machines we could again formulate another Gödelian formula, the Gödelian formula of these machines, that they are not able to proof but that we can recognize as true. More general arguments, such as the possibility to escape Gödelian argument by suggesting that Gödel’s theorem applies to consistent systems while we could be inconsistent ones, are moreover refuted by Lucas by maintaining that our inconsistency corresponds to occasional malfunctioning of a machine and not to his normal inconsistency; indeed, a inconsistent machine is characterized by producing any statement, on the contrary human being are selective and not disposed to assert anything.

The paper explores the main competing interpretations of Aristotle's view of the relation between happiness and external goods in the Nicomachean Ethics. On the basis of a careful analysis of what Aristotle says in the Nicomachean Ethics (and other works such as the Eudemian Ethics, Politics, Rhetoric, etc.) it is argued that it is likely that Aristotle takes at least some external goods to be actual constituents of happiness provided that (1) they are accompanied by virtuous activity and (2) the (...) agent enjoying and using those external goods does so in ways compatible with the continuous aim of acting virtuously.
