What are the philosophical views of professional philosophers, and how do these views change over time? The 2020 PhilPapers Survey surveyed around 2000 philosophers on 100 philosophical questions. The results provide a snapshot of the state of some central debates in philosophy, reveal correlations and demographic effects involving philosophers' views, and reveal some changes in philosophers' views over the last decade.

Indirect speech acts—responding “I forgot to wear my watch today” to someone who asked for the time—are ubiquitous in daily conversation, but are understudied in current neurobiological models of language. To comprehend an indirect speech act like this one, listeners must not only decode the lexical-semantic content of the utterance, but also make a pragmatic, bridging inference. This inference allows listeners to derive the speaker’s true, intended meaning—in the above dialog, for example, that the speaker cannot provide the time. In (...) the present work, we address this major gap by asking non-aphasic patients with behavioral variant frontotemporal dementia and brain-damaged controls with amnestic mild cognitive impairment to judge simple question-answer dialogs of the form: “Do you want some cake for dessert?” “I’m on a very strict diet right now,” and relate the results to structural and diffusion MRI. Accuracy and reaction time results demonstrate that subjects with bvFTD, but not MCI, are selectively impaired in indirect relative to direct speech act comprehension, due in part to their social and executive limitations, and performance is related to caregivers’ judgment of communication efficacy. MRI imaging associates the observed impairment in bvFTD to cortical thinning not only in traditional language-associated regions, but also in fronto-parietal regions implicated in social and executive cerebral networks. Finally, diffusion tensor imaging analyses implicate white matter tracts in both dorsal and ventral projection streams, including superior longitudinal fasciculus, frontal aslant, and uncinate fasciculus. These results have strong implications for updated neurobiological models of language, and emphasize a core, language-mediated social disorder in patients with bvFTD. (shrink)

Proof-theoretic semantics (P-tS) is an innovative approach to grounding logical meaning in terms of proofs rather than traditional truth-conditional semantics. The point is not that one provides a proof system, but rather that one articulates meaning in terms of proofs and provability. To elucidate this paradigm shift, we commence with an introduction that contrasts the fundamental tenets of P-tS with the more prevalent model-theoretic approach to semantics. The contribution of this paper is a P-tS for a substructural logic, intuitionistic multiplicative (...) linear logic (IMLL). Specifically, we meticulously examine and refine the established P-tS for intuitionistic propositional logic. Subsequently, we present two novel and comprehensive forms of P-tS for IMLL. Notably, the semantics for IMLL in this paper embodies its resource interpretation through its number-of-uses reading (restricted to atoms). This stands in contrast to the conventional model-theoretic semantics of the logic, underscoring the value that P-tS brings to substructural logics. (shrink)

In 2014, Colonel M. Shane Riza published an article in this journal arguing that remotely piloted aircraft and robotic weapons threaten the US Air Force’s warrior ethos. Riza has clearly articulated the sentiments of one side of a vibrant debate within our service. This paper presents an alternative view; a view held by some who have experienced these new forms and tools of war, and who have wrestled with their implications first-hand. In this paper, we address some methodological concerns with (...) Riza’s approach and then engage some misunderstandings about RPA’s relationship to military history and to risk. The second part of this paper takes a close look at some of the early Just War thinkers to determine what implications the tradition may have on the warrior ethos. We propose, as an alternative to Riza’s position, a return to an ethos grounded in humility, charity, and a conception of war as a last resort; in short, a return to the Just Warrior Ethos. (shrink)

This translation of Carlo Michelstaedter’s _Persuasion and Rhetoric_ brings the powerful and original work of a seminal cultural figure to English-language readers for the first time. Ostensibly a commentary on Plato’s and Aristotle’s relation to the pre-Socratic philosophers, Michelstaedter’s deeply personal book is an extraordinary rhetorical feat that reflects the author’s struggle to make sense of modern life. This edition includes an introduction discussing his life and work, an extensive bibliography, notes to introduce each chapter, and critical notes illuminating the (...) text. Within hours of completing _Persuasion and Rhetoric, _his doctoral thesis, 23-year-old Michelstaedter shot himself to death. The text he left behind has proved to be one of the most trenchant and influential studies in modern rhetoric, a work that develops Nietzschean themes and anticipates the conclusions of, among others, Martin Heidegger. Publication of the book in English is an event of great magnitude for students of Italian philosophy, rhetoric, and literature as well as the culture of Mitteleuropa. (shrink)

We consider a situation in which individuals search for accurate decisions without direct feedback on their accuracy, but with information about the decisions made by peers in their group. The “wisdom of crowds” hypothesis states that the average judgment of many individuals can give a good estimate of, for example, the outcomes of sporting events and the answers to trivia questions. Two conditions for the application of wisdom of crowds are that estimates should be independent and unbiased. Here, we study (...) how individuals integrate social information when answering trivia questions with answers that range between 0% and 100%. We find that, consistent with the wisdom of crowds hypothesis, average performance improves with group size. However, individuals show a consistent bias to produce estimates that are insufficiently extreme. We find that social information provides significant, albeit small, improvement to group performance. Outliers with answers far from the correct answer move toward the position of the group mean. Given that these outliers also tend to be nearer to 50% than do the answers of other group members, this move creates group polarization away from 50%. By looking at individual performance over different questions we find that some people are more likely to be affected by social influence than others. There is also evidence that people differ in their competence in answering questions, but lack of competence is not significantly correlated with willingness to change guesses. We develop a mathematical model based on these results that postulates a cognitive process in which people first decide whether to take into account peer guesses, and if so, to move in the direction of these guesses. The size of the move is proportional to the distance between their own guess and the average guess of the group. This model closely approximates the distribution of guess movements and shows how outlying incorrect opinions can be systematically removed from a group resulting, in some situations, in improved group performance. However, improvement is only predicted for cases in which the initial guesses of individuals in the group are biased. (shrink)

People who score high in the jumping to conclusions bias (JTC) require relatively little evidence to reach highly confident conclusions. However, they often feel as though they have done ample research in informing their decisions. What factors could account for this discrepancy? The current research examines one potential factor: how individuals (with varying degrees of the JTC bias) generate hypotheses to explain uncertain events prior to searching for evidence. Study 1 demonstrated that high JTC participants generated fewer hypotheses but were (...) more confident that one was right (compared to low JTC participants). Study 2 showed that, when given the choice between generating alternative hypotheses and supporting initial hypotheses, individuals high in JTC chose to support their initial hypotheses more often. Thus, while the JTC bias is associated with limited hypothesising for unexplained events, it also corresponds with “doubling down” and investing research efforts in confirming initial hunches.

The paper by Susan M. Wolf and Jeffrey P. Kahn published in this issue of the Journal of Law, Medicine & Ethics notes that we are members of the Working Group on Genetic Testing in Disability Insurance and that the members of the Working Group do not necessarily subscribe to its recommendations. Although we agree with some of Wolf and Kahn's recommendations, we do not agree with recommendations 1, 3, 4, and 5 for individual disability insurance and recommendations 1, 2, (...) and 3 for group disability insurance. We use this paper to delineate our areas of disagreement, but we do not discuss areas such as employment law as they are not our areas of expertise.First, understanding our roles on the Working Group is important. As members, we provided technical expertise on disability insurance. Our input to the Working Group represents our individual opinions. (shrink)

Deception has been practiced by sellers since the beginning of the marketplace. Research in marketing ethics has established benchmarks and parameters forethical behavior that include honesty, full disclosure, equity, and fairness. Deception in marketing, however, has not received the same level of attention. This paper proposes to treat deception in marketing within the context of criminology. By examining deception in marketing within the context of criminology, additional insight can be gained into identifying its antecendents and the likelihood of its occurrence. (...) To this end, deception in marketing is interpreted under the empathy/harm matrix, Cressey’s fraud triangle, and the transparency/time-lag matrix. These frameworks are then combined into a diagram detailing antecedents affecting the likelihood of marketing agents participating in deceptive marketing actions. A number of propositions are presented. (shrink)

Personal observations and survey data are used to examine the future of the village in a restructured food and agricultural sector in the former Soviet Union. Specific comparisons are made between the subjective quality of life of residents in two villages in the former Soviet Union (one in southern Russia and one in eastern Ukraine) and two villages in northwest Missouri. Residents of the Russian and Ukrainian villages have substantially lower assessments of specific domains of their lives than do American (...) villagers. Respondents in the Russian and Ukrainian sample express an interest in some aspects of privatization of services and consumer goods but, by and large, exhibit little interest in replacing the collective farms with household-level private farming. Historical factors, different incentive structures, and the possibilities for different institutional arrangements are discussed. (shrink)

Microscale techniques have been applied to biological assays for nearly two decades, but haven't been widely integrated as common tools in biological laboratories. The significant differences between several physical phenomena at the microscale versus the macroscale have been exploited to provide a variety of new types of assays (such as gradient production or spatial cell patterning). However, the use of these devices by biologists seems to be limited by issues regarding biological validation, ease of use, and the limited available readouts (...) for assays done using microtechnology. Critical validation work has been done recently that highlights the current challenges for microfluidic methods and suggest ways in which future devices might be improved to better integrate with biological assays. With more validation and improved designs, microscale techniques hold immense promise as a platform to study aspects of cell biology that are not possible using current macroscale techniques.

This book argues against the common view that there are no essential differences between Plato and the Neoplatonist philosopher, Plotinus, on the issues of mysticism, epistemology, and ethics. Beginning by examining the ways in which Plato and Plotinus claim that it is possible to have an ultimate experience that answers the most significant philosophical questions, David J. Yount provides an extended analysis of why we should interpret both philosophers as mystics. The book then moves on to demonstrate that both (...) philosophers share a belief in non-discursive knowledge and the methods to attain it, including dialectic and recollection, and shows that they do not essentially differ on any significant views on ethics. Making extensive use of primary and secondary sources, Plato and Plotinus on Mysticism, Epistemology and Ethics shows the similarities between the thought of these two philosophers on a variety of philosophical questions, such as meditation, divination, wisdom, knowledge, truth, happiness and love.

Translation of the genetic code occurs in a cycle where ribosomes engage mRNAs, synthesize protein, and then disengage in order to repeat the process again. The final part of this process—ribosome recycling, where ribosomes dissociate from mRNAs—involves a complex molecular choreography of specific protein factors to remove the large and small subunits of the ribosome in a coordinated fashion. Errors in this process can lead to the accumulation of ribosomes at stop codons or translation of downstream open reading frames (ORFs). (...) Ribosome recycling is also critical when a ribosome stalls during the elongation phase of translation and must be rescued to allow continued translation of the mRNA. Here we discuss the molecular interactions that drive ribosome recycling, and their regulation in the cell. We also examine the consequences of inefficient recycling with regards to disease, and its functional roles in synthesis of novel peptides, regulation of gene expression, and control of mRNA‐associated proteins. Alterations in ribosome recycling efficiency have the potential to impact many cellular functions but additional work is needed to understand how this regulatory power is utilized. (shrink)

Do we control what we believe? Are we responsible for what we believe? In a series of ten essays David Owens explores various different forms of control we might have over belief, and the different forms of responsibility these forms of control generate.

In response to a recent argument by David Bloor, I argue that denying absolutes does not necessarily lead to relativism, that one can be a fallibilist without being a relativist. At issue are the empirical natural sciences and what might be called “framework relativism”, that is, the idea that there is always a conceptual scheme or set of practices in use, and all observations are theory-laden relative to the framework. My strategy is to look at the elements that define (...) a relativist stance and show where the pragmatic fallibilist disagrees. Defending the pragmatic notion of experience will be central, given that relativists reject the idea that experience can play a role in objectively justifying belief. We can reject all absolutes and start from the premise that everything is historical, contingent, and situated. One of the lessons of pragmatism is that universal and fixed principles are not necessary for objective knowledge. (shrink)

The book examines one of the most contested topics in linguistics and cognitive science: the role of recursion in language. It offers a precise account of what recursion is, what role it should play in cognitive theories of human knowledge, and how it manifests itself in the mental representations of language and other cognitive domains.

Diderot is widely praised as a master of lively, dramatic and original dialogue. This book studies the developing role of dialogue in his early writings (1745 to 1754). Diderot's earlier experiments with the dialogue form, meticulously charted and analysed by D. J. Adams, opened the way to the exploration of human communication and cooperation which lies at the heart of the Encyclopédie. At first for Diderot dialogue ended in the triumph of monologue, with one speaker reducing another to silence. But (...) one of his central problems was precisely that of solipsism. Is it possible for people to communicate effectively with each other? By engaging with this problem in his early writings Diderot gradually came to realise the epistemological importance of true dialogue as an escape from the solipsistic trap; and, slowly and hesitantly, he developed the form of communicative dialogue which was to flourish in the masterpieces of his later years.

[This is an edited version of a keynote talk at the conference on Neural Information Processing Systems (NeurIPS) on November 28, 2022, with some minor additions and subtractions.] -/- There has recently been widespread discussion of whether large language models might be sentient or conscious. Should we take this idea seriously? I will break down the strongest reasons for and against. Given mainstream assumptions in the science of consciousness, there are significant obstacles to consciousness in current models: for example, their (...) lack of recurrent processing, a global workspace, and unified agency. At the same time, it is quite possible that these obstacles will be overcome in the next decade or so. I conclude that while it is somewhat unlikely that current large language models are conscious, we should take seriously the possibility that successors to large language models may be conscious in the not-too-distant future.

It is often thought that Aristotle restricts the scope of justice to existing communities. Against prominent treatments of this problem, this paper argues that while Aristotle does indeed restrict the scope of justice, he recognizes eudaimonic reasons to cultivate co-operative and benevolent relations and to eschew manipulative and exploitative ones. His limitation of justice to existing communities thereby avoids the unsavory implications often attributed to it.

Using the evolution of the stickleback family of subarctic fish as a touchstone, we explore the effect of new discoveries about regulatory genetics, developmental plasticity, and epigenetic inheritance on the conceptual foundations of the Modern Evolutionary Synthesis. Identifying the creativity of natural selection as the hallmark of the Modern Synthesis, we show that since its inception its adherents have pursued a variety of research projects that at first seemed to conflict with its principles, but were accommodated. We situate challenges coming (...) from developmental biology in a dialectic between innovation and tradition, suggesting on the basis of past episodes that even if developmental plasticity and epigenetic inheritance are aligned with its principles the Modern Synthesis will be significantly affected.

There is a long tradition in philosophy of using a priori methods to draw conclusions about what is possible and what is necessary, and often in turn to draw conclusions about matters of substantive metaphysics. Arguments like this typically have three steps: first an epistemic claim , from there to a modal claim , and from there to a metaphysical claim.

The use of deception in psychological research continues to be a controversial topic. Using Rawls's explication of utilitarianism, I attempt to demonstrate how professional organizations, such as the American Psychological Association, can provide more specific standards that determine the permissibility of deception in research. Specifically, I argue that researchers should examine the costs and benefits of creating and applying specific rules governing deception. To that end, I offer 3 recommendations. First, that researchers who use deception provide detailed accounts of the (...) procedures they used to minimize the harm created by deception in their research reports. Second, that the American Psychological Association offer a definition of deception that describes techniques commonly used in research. Finally, I recommend that the informed consent procedure be revised to indicate that the researcher may use deception as a part of the study. (shrink)

Bentham's dictum, ‘everybody to count for one, nobody for more than one’, is frequently noted but seldom discussed by commentators. Perhaps it is not thought contentious or exciting because interpreted as merely reminding the utilitarian legislator to make certain that each person's interests are included, that no one is missed, in working the felicific calculus. Since no interests are secure against the maximizing directive of the utility principle, which allows them to be overridden or sacrificed, the dictum is not usually (...) taken to be asserting fundamental rights that afford individuals normative protection against the actions of others or against legislative policies deemed socially expedient. Such non-conventional moral rights seem denied a place in a utilitarian theory so long as the maximization of aggregate happiness remains the ultimate standard and moral goal. (shrink)
