From certain sorts of premise, individuals reliably infer invalid conclusions. Two Experiments investigated a possible cause for these illusory inference: Reasoners fail to think about what is false. In Experiment 1, 24 undergraduates drew illusory and control inferences from premises based on exclusive disjunctions (“or else”). In one block, participants were instructed to falsify the premises of each illusory and control inference before making the inference. In the other block, participants did not receive these instructions. There were more correct answers (...) for illusory disjunctions whose premises had been falsified than there were for illusory disjunctions that had not been falsified. A second Experiment introduced illusory inferences in a real world context that accentuated falsification of premises. Accuracy also improved. Knowledge of how to falsify premises and to consider their implications for true premises transferred to a new problem introduced at the end of the Experiment without the falsification instruction. The participants' ratings of the difficulty of the inferences showed that they did not err simply because illusory inferences are perceived to be more difficult than control problems. The model theory predicts these results because it postulates that the limitations of working memory preclude the representation of false information. (shrink)

Most of the world now accepts the idea, first proposed four decades ago, that death means “brain death.” But the idea has always been open to criticism because it doesn't square with all of our intuitions about death. In fact, none of the possible definitions of death quite works. Death, perhaps surprisingly, eludes definition, and “brain death” can be accepted only as a refinement of what is in fact a fuzzy concept.

The equipoise requirement in clinical research demands that, if patients are to be randomly assigned to one of two interventions in a clinical trial, there must be genuine doubt about which is better. This reflects the traditional view that physicians must never knowingly compromise the care of their patients, even for the sake of future patients. Equipoise has proven to be deeply problematic, especially in the Third World. Some recent critics have argued against equipoise on the grounds that clinical research (...) is fundamentally distinct from clinical care, and thus should be governed by different norms. I argue against this "difference position," and instead take issue with the traditional, exclusively patient-centered account of physicians' obligations that equipoise presupposes. In place of this traditional view, I propose a Kantian test for the reasonable partiality that physicians should show their patients, focusing on its application in clinical research and medical education.

ABSTRACT The term “deep state” has enjoyed political prominence in recent years, especially in movements around former President Donald Trump. However, the term emerged in the activist milieu after the founding of Students for a Democratic Society, which sought to engender political realignment in the aftermath of the Kennedy assassination. Those on the far right who use the term to level accusations of conspiracy at supposed subversives in the administrative state are unwittingly drawing on a long-running but little-analyzed intellectual tradition. (...) In that tradition, conspiracy theories purport to unmask the real intentions of political actors in order to facilitate cooperation and recruitment across ideological and partisan divides. From the postwar period to the present, conspiracy theories, and the “deep state” vocabulary in particular, circulated freely across the left-right political divide. Authors and activists were attracted to these tropes and texts not merely because they appeared to reveal concrete truths about long-hidden elements of American political life, but also because their very ambiguity enabled them to be flexibly co-opted. Conspiracy theories allowed activists to mobilize around shared gaps in public knowledge about traumatic events like the assassination, activating public dissatisfaction with official explanations of those events. Their ambiguity, coupled with the seeming pervasiveness of conspiracy theorist tropes across political divides, appeared to activists seeking realignment of both the left and the right as a promising tactical opportunity to assert that they and their erstwhile enemies were actually engaged in a shared project. Activists thus came to see conspiracy theory not as the province of an exclusively left or right politics, but as an autonomous and contestable cultural space. This, in turn, led to cross-partisan encounters. (shrink)

We examine some of the ramifications of extended cognition for virtue epistemology by exploring the idea within extended cognition that it is possible to decentralize cognitive agency such that cognitive agency includes socio-cultural practices. In doing so, we first explore the (seemingly unquestioned) assumption in both virtue epistemology and extended cognition that cognitive agency is an individualistic phenomenon. A distributed notion of cognitive agency alters the landscape of knowledge attribution in virtue epistemology. We conclude by offering a pragmatic notion of (...) cognitive agency, where the situation sets the benchmarks for whether cognitive agency is individualistic or socio-culturally distributed.

Causal and counterfactual thoughts are bound together in Byrne's theory of human imagination. We think there are two issues in her theory that deserve clarification. First, Byrne describes which counterfactual possibilities we think of, but she leaves unexplained the mechanisms by which we generate these possibilities. Second, her exploration of and enablers gives two different predictions of which counterfactuals we think of in causal scenarios. On one account, we think of the counterfactuals which we have control over. On the other, (...) which counterfactuals we think of depends on whether something is a strong cause or an enabler. Although these two accounts sometimes give the same predictions, we present cases in which they differ, and we would like to see Byrne's theory provide a way of reconciling these differences.

The present situation in philosophy is paradoxical. On the one hand, thinking men and women all over the world are exclaiming that, while science has made sufficient advance to satisfy all our material needs, what we most need, and must find if we are not to suffer shipwreck, is a new sense of values, a new religious awakening and a new orientation towards life, in short a new philosophy. On the other hand, many professional philosophers are coming to hold the (...) view that philosophy has had its day, or rather that it never in any proper sense had its day, because it is not a rational enterprise but a mistake, an illusion, a farrago of nonsense, “a muddle arising out of the complexities of language.” A new inquiry which goes by the name of Analysis and resembles logic more closely than any other existing discipline is at once to give the quietus to philosophy and to reign in its stead. The modern philosopher cries, with Faustus, “Sweet Analytickes! 'tis thou hast ravished me.” I will not prejudice your minds at the outset by recalling where the study of analysis led the Doctor of Wurtemburg.Those who are thus forthrightly sceptical about philosophy and group themselves under the aegis of analysis are themselves divided into a number of sects. One and all, however, are relentless in exposing the weaknesses of philosophy, zealous in proselytizing and deadly in expounding their new technique which combines scholastic subtlety with modern scientific realism. They represent in fact a modern scholasticism loosely grouped round the dogma: “We pursue logical analysis, but not philosophy,” though, by a curious paradox which demands scrutiny, some of them say: “Philosophy is analysis.”.
