In this study on deduction, the authors argue that people reason by imagining the relevant state of affairs, ie building an internal model of it, formulating a tentative conclusion based on this model and then searching for alternative models.

Good reasoning can lead to success; bad reasoning can lead to catastrophe. Yet, it's not obvious how we reason, and why we make mistakes. This new book by one of the pioneers of the field, Philip Johnson-Laird, looks at the mental processes that underlie our reasoning. It provides the most accessible account yet of the science of reasoning.

Opponents of abortion are often described as ‘inconsistent’ (hypocrites) in terms of their beliefs, actions and/or priorities. They are alleged to do too little to combat spontaneous abortion, they should be adopting cryopreserved embryos with greater frequency and so on. These types of arguments—which we call ‘inconsistency arguments’—conform to a common pattern. Each specifies what consistent opponents of abortion would do (or believe), asserts that they fail to act (or believe) accordingly and concludes that they are inconsistent. Here, we show (...) that inconsistency arguments fail en masse. In short, inconsistency arguments typically face four problems. First, they usually fail to account for diversity among opponents of abortion. Second, they rely on inferences about consistency based on isolated beliefs shared by some opponents of abortion (and these inferences often do not survive once we consider other beliefs opponents of abortion tend to hold). Third, inconsistency arguments usually ignore the diverse ways in which opponents of abortion might act on their beliefs. Fourth, inconsistency arguments criticise groups of people without threatening their beliefs (eg, that abortion is immoral). Setting these problems aside, even supposing inconsistency arguments are successful, they hardly matter. In fact, in the two best-case scenarios—where inconsistency arguments succeed—they either encourage millions of people to make the world a (much) worse place (from the critic’s perspective) or promote epistemically and morally irresponsible practices. We conclude that a more valuable discussion would be had by focusing on the arguments made by opponents of abortion rather than opponents themselves. (shrink)

Most explanations of the rational authority of testimony provide little guidance when evaluating individual pieces of testimony. In practice, however, we are remarkably sensitive to the varying epistemic credentials of testimony: extending trust when it is deserved, and withholding it when it is not. A complete account of the epistemology of testimony should, then, have something to say about when it is that testimony is trustworthy. In the typical case, to judge someone trustworthy requires judging them to be competent and (...) sincere. In this essay we develop an exchange-based account of testimony that shows how those who receive testimony are in a position to evaluate the sincerity of speakers. (shrink)

William Simkulet has recently criticised Colgrove et al ’s defence against what they have called inconsistency arguments—arguments that claim opponents of abortion act in ways inconsistent with their underlying beliefs about human fetuses. Colgrove et al presented three objections to inconsistency arguments, which Simkulet argues are unconvincing. Further, he maintains that OAs who hold that the fetus is a person at conception fail to act on important issues such as the plight of frozen embryos, poverty and spontaneous abortion. Thus, they (...) are morally negligent. In response, we argue that Simkulet has targeted a very narrow group of OAs, and so his criticisms are inapplicable to most OAs. We then explain why his responses to each of Colgrove et al’s objections do not succeed, even for this restricted group. Finally, we note that Simkulet fails to provide evidence for his claims regarding OAs’ supposed failures to act, and we show that OAs veritably do invest resources into these important issues. We conclude that Colgrove et al ’s reasons for rejecting inconsistency arguments remain intact. (shrink)

The rapid development of artificial womb technologies means that we must consider if and when it is permissible to kill the human subject of ectogestation—recently termed a ‘gestateling’ by Elizabeth Chloe Romanis—prior to ‘birth’. We describe the act of deliberately killing the gestateling as gestaticide, and argue that there are good reasons to maintain that gestaticide is morally equivalent to infanticide, which we consider to be morally impermissible. First, we argue that gestaticide is harder to justify than abortion, primarily because (...) the gestateling is completely independent of its biological parents. Second, we argue that gestaticide is morally equivalent to infanticide. To demonstrate this, we explain that gestatelings are born in a straightforward sense, which entails that killing them is infanticide. However, to strengthen our overall claim, we also show that if gestatelings are not considered to have been born, killing them is still equivalent to killing neonates with congenital anomalies and disabilities, which again is infanticide. We conclude by considering how our discussion of gestaticide has implications for the permissibility of withdrawing life-sustaining treatment from gestatelings. (shrink)

BackgroundWinning funding for health and medical research usually involves a lengthy application process. With success rates under 20%, much of the time spent by 80% of applicants could have been better used on actual research. An alternative funding system that could save time is using democracy to award the most deserving researchers based on votes from the research community. We aimed to pilot how such a system could work and examine some potential biases.MethodsWe used an online survey with a convenience (...) sample of Australian researchers. Researchers were asked to name the 10 scientists currently working in Australia that they thought most deserved funding for future research. For comparison, we used recent winners from large national fellowship schemes that used traditional peer review.ResultsVoting took a median of 5 min (inter-quartile range 3 to 10 min). Extrapolating to a national voting scheme, we estimate 599 working days of voting time (95% CI 490 to 728), compared with 827 working days for the current peer review system for fellowships. The gender ratio in the votes was a more equal 45:55 (female to male) compared with 34:66 in recent fellowship winners, although this could be explained by Simpson’s paradox. Voters were biased towards their own institution, with an additional 1.6 votes per ballot (inter-quartile range 0.8 to 2.2) above the expected number. Respondents raised many concerns about the idea of using democracy to fund research, including vote rigging, lobbying and it becoming a popularity contest.ConclusionsThis is a preliminary study of using voting that does not investigate many of the concerns about how a voting system would work. We were able to show that voting would take less time than traditional peer review and would spread the workload over many more reviewers. Further studies of alternative funding systems are needed as well as a wide discussion with the research community about potential changes. (shrink)

Deep convolutional networks exceed humans in sensitivity to local image properties, but unlike biological vision systems, do not discover and encode abstract relations that capture important properties of objects and events in the world. Coupling network architectures with additional machinery for encoding abstract relations will make deep networks better models of human abilities and more versatile and capable artificial devices.

We developed a technique to examine the effects of emotional content and context on verbal memory. Two sets of sentences were devised: in the first, each sentence was emotionally arousing due to the inclusion of an emotional “target” word. In the second set, “targets” were replaced with well-matched neutral words. Subjects read aloud a selection of emotional and neutral sentences, and were then surprised with memory tasks after a range of time delays. Emotional target words were remembered significantly better than (...) neutral words in all experiments. Recognition of emotional words was relatively stable despite increasing delays between encoding and recognition testing, in contrast to memory for neutral words, which decayed over time. Memory for neutral non-target words was enhanced when words had been presented in an emotional context. The results confirm the phenomenon of emotional enhancement of memory at short and long delays and suggest that emotional context may be encoded independently of word meaning. (shrink)

© Ginn et al. 2016.The indexing methods currently used for serial femtosecond crystallography were originally developed for experiments in which crystals are rotated in the X-ray beam, providing significant three-dimensional information. On the other hand, shots from both X-ray free-electron lasers and serial synchrotron crystallography experiments are still images, in which the few three-dimensional data available arise only from the curvature of the Ewald sphere. Traditional synchrotron crystallography methods are thus less well suited to still image data processing. Here, a (...) new indexing method is presented with the aim of maximizing information use from a still image given the known unit-cell dimensions and space group. Efficacy for cubic, hexagonal and orthorhombic space groups is shown, and for those showing some evidence of diffraction the indexing rate ranged from 90% to 151%. Here, the indexing rate refers to the number of lattices indexed per image. (shrink)

DBS Think Tank IX was held on August 25–27, 2021 in Orlando FL with US based participants largely in person and overseas participants joining by video conferencing technology. The DBS Think Tank was founded in 2012 and provides an open platform where clinicians, engineers and researchers can freely discuss current and emerging deep brain stimulation technologies as well as the logistical and ethical issues facing the field. The consensus among the DBS Think Tank IX speakers was that DBS expanded in (...) its scope and has been applied to multiple brain disorders in an effort to modulate neural circuitry. After collectively sharing our experiences, it was estimated that globally more than 230,000 DBS devices have been implanted for neurological and neuropsychiatric disorders. As such, this year’s meeting was focused on advances in the following areas: neuromodulation in Europe, Asia and Australia; cutting-edge technologies, neuroethics, interventional psychiatry, adaptive DBS, neuromodulation for pain, network neuromodulation for epilepsy and neuromodulation for traumatic brain injury.

In the debate over whether mathematical facts, properties, or entities explain physical events (in what philosophers call “extra-mathematical” explanations), Aidan Lyon’s (2012) affirmative answer stands out for its employment of the program explanation (PE) methodology of Frank Jackson and Philip Pettit (1990). Juha Saatsi (2012; 2016) objects, however, that Lyon’s examples from the indispensabilist literature are (i) unsuitable for PE, (ii) nominalizable into non-mathematical terms, and (iii) mysterious about the explanatory relation alleged to obtain between the PE’s mathematical explanantia (...) and physical explananda. In this paper, I propose a counterexample to Saatsi’s objections. My counterexample is Frank Jackson’s (1998a) program explanation for color experience, which I argue needs recasting as an extra-mathematical PE due to its implicit reliance on reflectance, a property that suffers conceptual regress unless redefined with Fourier harmonics. Pace Saatsi, I argue that this recast example is an authoritative PE, non-nominalizable, and minimally esoteric. Important for the indispensability debate at large, moreover, is that my counterexample reifies Fourier harmonics without the Enhanced Indispensability Argument (an argument to which Lyon applies PE as a premise). Indispensabilists have long overlooked the conditionalization of a limited mathematical realism on property realism, and my counterexample to Saatsi exploits this conditionalization. (shrink)

Imperialism seems to be deeply antithetical to democracy. Yet, at least one form of imperialism – what I call “hands-off imperialism" – seems to be perfectly compatible with the kind of self-governance commonly thought to be the hallmark of democracy. The solution to this puzzle is to recognize that democracy involves more than self-governance. Rather, it involves what I call self-rule. Self-rule is an example of what Philip Pettit has called a modally demanding value. Modally demanding values are, roughly, (...) values the instantiation of which depends not only on what actually happens, but on what would happen in certain non-actual circumstances. Self-rule is the modally demanding counterpart of self-governance, since it requires, not merely that the members of a state actually govern themselves, but that they would continue to do so across a range of non-actual situations. Moreover, the value of self-rule (and hence democracy) is not reducible to the value of self-governance. Understanding the modally demanding character of democracy allows us to appreciate what is democratically objectionable about occupation by a foreign power, even if there is no prospect of the foreign power intervening in the governance of the occupied state by its members.

This paper critically examines what Nicholas Wolterstorff has to say in Divine Discourse in response to the two questions in the title. It tries to show that his argument for the conclusion that God can have the obligations of a speaker is defective. It also tries to show that his argument for the conclusion that some actual person is entitled to believe that God has spoken to her is incomplete. The paper's conclusion is that Wolterstorff's arguments fail to establish, (...) or to provide strong grounds for accepting, a positive answer to either of the questions in its title. (shrink)

Other Frege works have long been available in English. The earlier Grundlagen der Arithmetik was nicely, if not always entirely accurately, translated by J. L. Austin and published in 1950.1 Translations of Frege’s other philosophical writings began to appear in influential editions about the same time,2 initially a small corpus that has been gradually added to over the years to include works from his Nachlass and letters from his correspondence.3 Somewhat later, the Begriffsschrift, Frege’s momentous first 1 The Foundations of Arithmetic (Oxford: Blackwell, 1950; 2nd edn. 1953). The later translation under the same title by Dale Jacquette (London: Longman, 2007) is much less satisfactory. 2 The first importance source for these was Peter Geach and Max Black’s Translations from the Philosophical Writing of Gottlob Frege (1952; 2nd edn. 1960; 3rd edn. 1980), though it included reprints of some much earlier translations. 3 The two most comprehensive English sources for the shorter writings are now Brian d= Reviews 177 c:\users\ken\documents\type3402\rj 3402 050 red.docx 2015-02-04 9:19 PM contribution to modern logic, the work which Quine 4 said had made logic a great subject, was translated in full despite the difficulties of Fregean notation.5 But through all this the Grundgesetze remained largely (though not entirely ) untranslated. The view seems, for a long time, to have been that Frege’s contributions to logic were to be found in the Begriffsschrift and his contributions to philosophy in the Grundlagen and a small number of seminal articles. The Grundgesetze, on the other hand, was widely thought not to have added much to these magni ficent achievements, but to have employed them in a project that was doomed by the discovery of Russell’s paradox; namely, the attempt to show that arithmetic could be rigorously derived from purely logical principles. In the bleak aftermath of Russell’s paradox it came to seem as if whatever was of value in the Grundgesetze had already been published elsewhere, while what was new in it was mistaken.6 That assessment of the book’s value, combined with the huge difficulties of typesetting Frege’s idiosyncratic two-dimensional notation, and the sheer scale of the work (even without the anticipated third volume, which was abandoned in the face of Russell’s paradox, it was, by far, Frege’s largest work) made it seem as though a translation of the whole Grundgesetze was not only a prohibitively large undertaking, but also one which was not really necessary. And so, through much of the twentieth century, the Grundgesetze vied with Principia Mathematica as the world’s bestknown but least-read philosophical book. But this understanding of the Grundgesetze’s importance could not withstand the development of neo-logicism, brought to prominence by Crispin Wright’s Frege’s Conception of Numbers as Objects.7 The key insight of neoMcGuinness, ed., Frege, Collected Papers on Mathematics, Logic, and Philosophy (1984); and Michael Beaney, ed., The Frege Reader (1997). 4 At least in early editions of Mathematical Logic.

Efforts to use concepts from contemporary biology in understanding the dissemination of culture have been inspired by two main analogies. One of these supposes that there are cultural units—memes—that share important similarities with genes, and a number of authors have attempted to exploit this analogy to develop precise theories of cultural transmission. According to a second analogy, the spread of culture is like the infection of a population by a virus. Very often, the two analogies are developed in tandem: Dawkins’s (...) introduction of the meme contains both his own assimilation of memes to genes and explicit approval of an elegant formulation of the view of memes as parasites by his then-colleague Nicholas Humphrey ; similarly, Daniel Dennett’s influential presentation of cultural transmission as the spread of memes appeals to one or other analogy indifferently as if they were equivalent. My aim in what follows is to take a hard look at the second analogy, treating it with a bit more precision than is customary. We’ll find that the formal details of transmission processes are by no means equivalent, and that even the kinematics is more complicated than seems to have been appreciated. (shrink)

In it Robert Audi and Nicholas Wolterstorff debate the place of religious convictions in politics. First, each of them presents an initial statement of his own views. Next, each of them responds critically to the views of the other. And, finally, Audi provides a brief summary of the chief points of agreement and disagreement. The two initial statements are expanded versions of papers (...) Audi and Wolterstorff presented at a conference on religion and liberalism at the University of Notre Dame. Those papers are included in a recently published volume of conference proceedings. (shrink)

Key ideas in the work of Michel Foucault are explored and applied to the organized pursuit of knowledge in higher education. His association of power and knowledge accounts for deeply rooted practices in higher education that would need to be mediated or overcome for there to be a revolution in inquiry to occur, such as the one advanced by Nicholas Maxwell. Foucault’s concepts of disciplinary power and bio-power, and how they act to manage the behavior of free citizens, are (...) described. These concepts are then applied to free inquiry, to show how the activity of individual inquirers is managed and how critical inquiry is controlled. The management of inquiry involving four norms, two of them intrinsic to inquiry and the other two extrinsic, is explained. The potential of Foucault’s concept of discursive formations is introduced as a means of reconceiving inquiry to overcome these impediments to a revolution in inquiry. (shrink)

One of my friends defends liberalism but disavows knowing much about Rawls; he is more concerned with Jefferson and other traditional liberals. Philip Selznick’s The Communitarian Persuasion is written specifically for such a Jeffersonian liberal, for Selznick discusses the liberalism of Madison, Jefferson, Dewey, and the legal tradition more so than that of Rawls and Dworkin.

In mainstream analytic epistemology, Reformed theology has made its presence prominently felt in Reformed epistemology, the view of religious belief according to which religious beliefs can be properly basic and warranted when formed by the proper functioning of the sensus divinitatis, an inborn capacity or faculty for belief in God that can be prompted to generate certain religious beliefs when presented with things (e.g., certain majestic aspects of creation). A major competitor to Reformed epistemology is Wittgensteinian quasi-fideism, a position drawn (...) from the epistemology of Wittgenstein’s On Certainty, according to which some foundational religious commitments are not properly basic beliefs but some kind of apodictic, unshakeable certainties that form part of the structure of one’s rationality and worldview. I argue that the Reformed tradition has contained elements of quasi-fideism at least as far back as Calvin’s account of faith from the Institutes of the Christian Religion, book 3, chapter 2.
