In the theory-dominated view of scientific experimentation, all relations of theory and experiment are taken on a par; namely, that experiments are performed solely to ascertain the conclusions of scientific theories. As a result, different aspects of experimentation and of the relation of theory to experiment remain undifferentiated. This in turn fosters a notion of theory-ladenness of experimentation that is too coarse-grained to accurately describe the relations of theory and experiment in scientific practice. By contrast, in this article, I suggest (...) that TLE should be understood as an umbrella concept that has different senses. To this end, I introduce a three-fold distinction among the theories of high-energy particle physics as background theories, model theories and phenomenological models. Drawing on this categorization, I contrast two types of experimentation, namely, “theory-driven” and “exploratory” experiments, and I distinguish between the “weak” and “strong” senses of TLE in the context of scattering experiments from the history of HEP. This distinction enables to identify the exploratory character of the deep-inelastic electron-proton scattering experiments—performed at the Stanford Linear Accelerator Center between the years 1967 and 1973—thereby shedding light on a crucial phase of the history of HEP, namely, the discovery of “scaling”, which was the decisive step towards the construction of quantum chromo-dynamics as a gauge theory of strong interactions.

It is generally accepted that Popper‘s degree of corroboration, though “inductivist” in a very general and weak sense, is not inductivist in a strong sense, i.e. when by ‘inductivism’ we mean the thesis that the right measure of evidential support has a probabilistic character. The aim of this paper is to challenge this common view by arguing that Popper can be regarded as an inductivist, not only in the weak broad sense but also in (...) a narrower, probabilistic sense. In section 2, first, I begin by briefly characterizing the relevant notion of inductivism that is at stake here; second, I present and discuss the main Popperian argument against it and show that in the only reading in which the argument is formally it is restricted to cases of predicted evidence, and that even if restricted in this way the argument is formally valid it is nevertheless materially unsound. In section 3, I analyze the desiderata that, according to Popper, any acceptable measure for evidential support must satisfy, I clean away its ad-hoc components and show that all the remaining desiderata are satisfied by inductuvist-in-strict-sense measures. In section 4 I demonstrate that two of these desiderata, accepted by Popper, imply that in cases of predicted evidence any measure that satisfies them is qualitatively indistinguishable from conditional probability. Finally I defend that this amounts to a kind of strong inductivism that enters into conflict with Popper’s anti-inductivist argument and declarations, and that this conflict does not depend on the incremental versus non-incremental distinction for evidential-support measures, making Popper’s position inconsistent in any reading.Keywords: Popper; Inductivism; Confirmation; Corroboration.

The pace of change in the world is accelerating, yet educational institutions have not kept pace. Indeed, schools have historically been the most static of social institutions, uncritically passing down from generation to generation outmoded didactic, lecture-and-drill-based, models of instruction. Predictable results follow. Students, on the whole, do not learn how to work by, or think for, themselves. They do not learn how to gather, analyze, synthesize and assess information. They do not learn how to analyze the diverse logic of (...) the questions and problems they face and hence how to adjust their thinking to those problems. They do not learn how to enter sympathetically into the thinking of others, nor how to deal rationally with conflicting points of view. They do not learn to become critical readers, writers, speakers and listeners. They do not learn how to use their native languages clearly, precisely, or persuasively. They do not, therefore, become ‘literate’, in the proper sense of the word. Neither do they gain much in the way of genuine knowledge since, for the most part, they could not explain the basis for what they believe. They would be hard pressed to explain, for example, which of their beliefs were based on rational assent and which on simple conformity to what they have been told. They have little sense as to how they might critically analyze their own experience, or identify national or group bias in their own thinking. They are much more apt to learn on the basis of irrational than rational modes of thought. They lack the traits of mind of a genuinely educated person: intellectual humility, courage, integrity, perseverance, and faith in reason.Happily, there is a movement in education today striving to address these problems in a global way, with strategies and materials for the modification of instruction at all levels of education. At its foundation is an emerging new theory of knowledge, learning, and literacy, one which recognizes the centrality of independent critical thinking to all substantial learning, one which recognizes that higher-order, multilogical thinking is as important to childhood as to adult learning, and as important to foundational learning in monological as in multilogical disciplines. This educational reform movement is not proposing an educational miracle cure, for its leading proponents recognize that many social and historical forces must come together before the ideals of the critical thinking movement will become a full academic reality. Schools do not exist in a social vacuum. To the extent that the broader society is uncritical so, on the whole, will be society's schools. Nevertheless, the social conditions necessary for fundamental changes in schooling are increasingly apparent. The pressure for fundamental change is growing. Whether and to what extent these needed basic changes will be delayed or side-tracked, thus requiring new periodic resurgences of this movement, with new, more elaborate articulations of its ideals, goals, and methods — only time will tell.

In this paper it is shown how plausible reasoning of the kind illustrated in the ancient Greek example of the weak and strong man can be analyzed and evaluated using a procedure in which the pro evidence is weighed against the con evidence using formal, computational argumentation tools.

The paper extends previous work on this example by using three new multiagent argumentation schemes closely related to the scheme for argument from negative consequences. (shrink)

This study investigates the social–psychological mechanisms leading individuals in organizations to engage in environmental citizenship behaviors, which entail keeping abreast of, and participating in, the environmental affairs of a company. Informed by the corporate greening and organizational behavior literature, we suggested that an employee’s level of involvement in the management of a company’s environmental impact was the overt manifestation of his or her discretionary sense of commitment to environmental concerns in the work context, and that such commitment developed through (...) the interplay of individual, organizational, and supervisory factors. Our general findings support the idea that when environmental protection is valued and encouraged by the company and line managers, organization members are more likely to experience a volitional sense of attachment and responsibility to corporate environmental goals and values, which is enacted through citizenship behaviors. We also expected that individual ecological beliefs would strengthen the environmental commitment of employees via identification with, and adherence to, the socially responsible cause embodied by the organization and its managerial staff. But it did not. On the contrary, the data indicated that corporate environmental policy is more likely to influence an employee’s level of environmental commitment when he or she holds weak versus strong personal ecological beliefs. Theoretical and managerial implications of our findings are discussed. (shrink)

The meaning of sustainability is the subject of intense debate among environmental and resource economists. Perhaps no other issue separates more clearly the traditional economic view from the views of most natural scientists. The debate currently focuses on the substitutability between the economy and the environment or between “natural capital” and “manufactured capital”—a debate captured in terms of weak versus strong sustainability. In this article, we examine the various interpretations of these concepts. We conclude that natural science (...) and economic perspectives on sustainability are inconsistent. The market-based Hartwick-Solow “weak sustainability” approach is far removed from both the ecosystem-based “Holling sustainability” and the “strong sustainability” approach of Daly and others. Each of these sustainability criteria implies a specific valuation approach, and thus an ethical position, to support monetary indicators of sustainability such as a green or sustainable Gross Domestic Product (GDP). The conflict between “weak sustainability” and “strong sustainability” is more evident in the context of centralized than decentralized decision making. In particular, firms selling “services” instead of material goods and regarding the latter as “capital” leads to decisions more or less consistent with either type of sustainability. Finally, we discuss the implications of global sustainability for such open systems as regions and countries. Open systems have not been dealt with systematically for any of the sustainability criteria. (shrink)

This chapter focuses on the issue of methodological usefulness of a strong versus weak adaptationist position in attempting to gain significant insight and to make scientifically important advances and discoveries in human cognition. Strong adaptationism holds that complex design is best explained by task-specific adaptations to particular ancestral environments; whereas weak adaptationism claims that we should not assume that complex design is the result of such narrowly determined task- or niche-specific evolutionary pressures in the absence (...) of substantial corroborating evidence. It argues that in cases of certain domain-specific cognitive competencies strong adaptationism has proven useful but not necessary to recent progress in the field. In other cases, a weak adaptationist strategy has been arguably most productive in advancing scientific understanding, without precluding that the structures uncovered by other means are actually adaptations.

This paper argues that a strong-sense Buddhist nominalism, which denies any resemblance between two things, even among natural kinds, fails to explain why names and concepts can successfully identify a group among other things. Drawing evidence from the theory of the three natures in two major Yogācāra texts—the Saṃdhinirmocana-sūtra and the Mahāyānasaṃgraha—I propose that these two texts affirm the affinity between concepts and things because they hold that it is the utilization of concepts in previous lives that gives (...) rise to our shared world. While rejecting the idea that there is an inherent property or universal shared by natural kinds, these two texts agree that natural kinds are regulated by concepts and therefore share some features from among the set of characteristics defined by those concepts. I therefore propose a weak-sense Buddhist nominalism that endorses the idea that natural kinds share resemblances. (shrink)

This paper is a study of similarities and differences between strong and weak quantum consequence operations determined by a given class of ortholattices.

My argument in this paper is that humility is implied in the concept of teaching, if teaching is construed in a strong sense. Teaching in a strong sense is a view of teaching as linked to students’ embodied experiences (including cognitive and moral-social dimensions), in particular students’ experiences of limitation, whereas a weak sense of teaching refers to teaching as narrowly focused on student cognitive development. In addition to detailing the relation between humility and (...) strong sense teaching, I will also argue that humility is acquired through the practice of teaching. My discussion connects to the growing interest, especially in virtue epistemology discourse, in the idea that teachers should educate for virtues. Drawing upon John Dewey and contemporary virtue epistemology discourse, I discuss humility, paying particular attention to an overlooked aspect of humility that I refer to as the educative dimension of humility. I then connect this concept of humility to the notion of teaching in a strong sense. In the final section, I discuss how humility in teaching is learned in the practice of teaching by listening to students in particular ways. In addition, I make connections between my concept of teaching and the practice of cultivating students’ virtues. I conclude with a critique of common practices of evaluating good teaching, which I situate within the context of international educational policy on teacher evaluation. (shrink)

Fine has shown that assigning any value to the Pasadena game is consistent with a certain standard set of axioms for decision theory. However, I suggest that it might be reasonable to believe that the value of an individual game is constrained by the long-run payout of repeated plays of the game. Although there is no value that repeated plays of the Pasadena game converges to in the standard strong sense, I show that there is a weaker sort (...) of convergence it exhibits, and use this to define a notion of ‘weak expectation’ that can give values to the Pasadena game and many others, though not to all games that fail to have a strong expectation in the standard sense.

In a standard sense, consistency and paraconsistency are understood as the absence of any contradiction and as the absence of the ECQ (‘E contradictione quodlibet’) rule, respectively. The concepts of weak consistency (in two different senses) as well as that of F -consistency have been defined by the authors. The aim of this paper is (a) to define alternative (to the standard one) concepts of paraconsistency in respect of the aforementioned notions of weak consistency and F -consistency; (...) (b) to define the concept of strong paraconsistency; (c) to build up a series of strongly paraconsistent logics; (d) to define the basic constructive logic adequate to a rather weak sense of consistency.

All of them are sound and complete in respect a modification of Routley and Meyer’s ternary relational semantics for relevant logics (no logic in this paper is relevant). (shrink)

The current debate on artificial intelligence (AI) tends to associate AI imaginaries with the vision of a future technology capable of emulating or surpassing human intelligence. This article advocates for a more nuanced analysis of AI imaginaries, distinguishing “strong AI narratives,” i.e., narratives that envision futurable AI technologies that are virtually indistinguishable from humans, from "weak" AI narratives, i.e., narratives that discuss and make sense of the functioning and implications of existing AI technologies. Drawing on the academic (...) literature on AI narratives and imaginaries and examining examples drawn from the debate on Large Language Models and public policy, we underscore the critical role and interplay of weak and strong AI across public/private and fictional/non-fictional discourses. The resulting analytical framework aims to empower approaches that are more sensitive to the heterogeneity of AI narratives while also advocating normalising AI narratives, i.e., positioning weak AI narratives more firmly at the center stage of public debates about emerging technologies.

It is common in recent epistemology to distinguish different senses, or conceptions, of epistemic justification. The proposed oppositions include the objective/subjective, internalist/externalist, regulative/nonregulative, resource-relative/resource-independent, personal/verific, and deontological/evaluative conceptions of justification. In some of these cases, writers regard both members of the contrasting pair as legitimate; in other cases only one member. In this paper I want to propose another contrasting pair of conceptions of justification, and hold that both are defensible and legitimate. The contrast will then be used to construct (...) a modified version of reliabilism, one which handles certain problem cases more naturally than my previous versions of reliabilism. (shrink)

ABSTRACT I argue that this examination and appreciation for the shift to abductive reasoning should be extended to the intersection of neuroscience and novel brain-computer interfaces too. This paper highlights the implications of applying abductive reasoning to personalized implantable neurotechnologies. Then, it explores whether abductive reasoning is sufficient to justify insurance coverage for devices absent widespread clinical trials, which are better applied to one-size-fits-all treatments. INTRODUCTION In contrast to the classic model of randomized-control trials, often with a large number of (...) subjects enrolled, precision medicine attempts to optimize therapeutic outcomes by focusing on the individual.[i] A recent publication highlights the strengths and weakness of both traditional evidence-based medicine and precision medicine.[ii] Plus, it outlines a tension in the shift from evidence-based medicine’s inductive reasoning style (the collection of data to postulate general theories) to precision medicine’s abductive reasoning style (the generation of an idea from the limited data available).[iii] The paper’s main example is the application of precision medicine for the treatment of cancer.[iv] I argue that this examination and appreciation for the shift to abductive reasoning should be extended to the intersection of neuroscience and novel brain-computer interfaces too. As the name suggests, brain-computer interfaces are a significant advancement in neurotechnology that directly connects someone’s brain to external or implanted devices.[v] Among the various kinds of brain-computer interfaces, adaptive deep brain stimulation devices require numerous personalized adjustments to their settings during the implantation and computation stages in order to provide adequate relief to patients with treatment-resistant disorders. What makes these devices unique is how adaptive deep brain stimulation integrates a sensory component to initiate the stimulation. While not commonly at the level of sophistication as self-supervising or generative large language models,[vi] they currently allow for a semi-autonomous form of neuromodulation. This paper highlights the implications of applying abductive reasoning to personalized implantable neurotechnologies. Then, it explores whether abductive reasoning is sufficient to justify insurance coverage for devices absent widespread clinical trials, which are better applied to one-size-fits-all treatments.[vii] ANALYSIS I. The State of Precision Medicine in Oncology and the Epistemological Shift While a thorough overview of precision medicine for the treatment of cancer is beyond the scope of this article, its practice can be roughly summarized as identifying clinically significant characteristics a patient possesses (e.g., genetic traits) to land on a specialized treatment option that, theoretically, should benefit the patient the most.[viii] However, in such a practice of stratification patients fall into smaller and smaller populations and the quality of evidence that can be applied to anyone outside these decreases in turn.[ix] As inductive logic helps to articulate, the greater the number of patients that respond to a particular therapy the higher the probability of its efficacy. By straying from this logical framework, precision medicine opens the treatment of cancer to more uncertainty about the validity of these approaches to the resulting disease subcategories.[x] Thus, while contemporary medical practices explicitly describe some treatments as “personalized”, they ought not be viewed as inherently better founded than other therapies.[xi] A relevant contemporary case of precision medicine out of Norway focuses on the care of a patient with cancer between the ventricles of the heart and esophagus, which had failed to respond to the standard regimen of therapies over four years.[xii] In a last-ditch effort, the patient elected to pay out-of-pocket for an experimental immunotherapy (nivolumab) at a private hospital. He experienced marked improvements and a reduction in the size of the tumor. Understandably, the patient tried to pursue further rounds of nivolumab at a public hospital. However, the hospital initially declined to pay for it given the “lack of evidence from randomised clinical trials for this drug relating to this [patient’s] condition.”[xiii] In rebuttal to this claim, the patient countered that he was actually similar to a subpopulation of patients who responded in “open‐label, single arm, phase 2 studies on another immune therapy drug” (pembrolizumab).[xiv] Given this interpretation of the prior studies and the patient’s response, further rounds of nivolumab were approved. Had the patient not had improvements in the tumor’s size following a round of nivolumab, then pembrolizumab’s prior empirical evidence in isolation would have been insufficient, inductively speaking, to justify his continued use of nivolumab.[xv] The case demonstrates a shift in reasoning from the traditional induction to abduction. The phenomenon of ‘cancer improvement’ is considered causally linked to nivolumab and its underlying physiological mechanisms.[xvi] However, “the weakness of abductions is that there may always be some other better, unknown explanation for an effect. The patient may for example belong to a special subgroup that spontaneously improves, or the change may be a placebo effect. This does not mean, however, that abductive inferences cannot be strong or reasonable, in the sense that they can make a conclusion probable.”[xvii] To demonstrate the limitations of relying on the abductive standard in isolation, commentators have pointed out that side effects in precision medicine are hard to rule out as being related to the initial intervention itself unless trends from a group of patients are taken into consideration.[xviii] As artificial intelligence (AI) assists the development of precision medicine for oncology, this uncertainty ought to be taken into consideration. The implementation of AI has been crucial to the development of precision medicine by providing a way to combine large patient datasets or a single patient with a large number of unique variables with machine learning to recommend matches based on statistics and probability of success upon which practitioners can base medical recommendations.[xix] The AI is usually not establishing a causal relationship[xx] – it is predicting. So, as AI bleeds into medical devices, like brain-computer interfaces, the same cautions about using abductive reasoning alone should be carried over. II. Responsive Neurostimulation, AI, and Personalized Medicine Like precision medicine in cancer treatment, computer-brain interface technology similarly focuses on the individual patient through personalized settings. In order to properly expose the intersection of AI, precision medicine, abductive reasoning, and implantable neurotechnologies, the descriptions of adaptive deep brain stimulation systems need to deepen.[xxi] As a broad summary of adaptive deep brain stimulation, to provide a patient with the therapeutic stimulation, a neural signal, typically referred to as a local field potential,[xxii] must first be detected and then interpreted by the device. The main adaptive deep brain stimulation device with premarket approval, the NeuroPace Responsive Neurostimulation system, is used to treat epilepsy by detecting and storing “programmer-defined phenomena.”[xxiii] Providers can optimize the detection settings of the device to align with the patient’s unique electrographic seizures as well as personalize the reacting stimulation’s parameters.[xxiv] The provider adjusts the technology based on trial and error. One day machine learning algorithms will be able to regularly aid this process in myriad ways, such as by identifying the specific stimulation settings a patient may respond to ahead of time based on their electrophysiological signatures.[xxv] Either way, with AI or programmers, adaptive neurostimulation technologies are individualized and therefore operate in line with precision medicine rather than standard treatments based on large clinical trials. Contemporary neurostimulation devices are not usually sophisticated enough to be prominent in AI discussions where the topics of neural networks, deep learning, generative models, and self-attention dominate the conversation. However, implantable high-density electrocorticography arrays (a much more sensitive version than adaptive deep brain stimulation systems use) have been used in combination with neural networks to help patients with neurologic deficits from a prior stroke “speak” through a virtual avatar.[xxvi] In some experimental situations, algorithms are optimizing stimulation parameters with increasing levels of independence.[xxvii] An example of neurostimulation that is analogous to the use of nivolumab in Norway surrounds a patient in the United States who was experiencing both treatment-resistant OCD and temporal lobe epilepsy.[xxviii]Given the refractory nature of her epilepsy, implantation of an adaptive deep brain stimulation system was indicated. As a form of experimental therapy, her treatment-resistant OCD was also indicated for the off-label use of an adaptive deep brain stimulation set-up. Another deep brain stimulation lead, other than the one implanted for epilepsy, was placed in the patient’s right nucleus accumbens and ventral pallidum region given the correlation these nuclei had with OCD symptoms in prior research. Following this, the patient underwent “1) ambulatory, patient-initiated magnet-swipe storage of data during moments of obsessive thoughts; (2) lab-based, naturalistic provocation of OCD-related distress (naturalistic provocation task); and (3) lab-based, VR [virtual reality] provocation of OCD-related distress (VR provocation task).”[xxix] Such signals were used to identify when to deliver the therapeutic stimulation in order to counter the OCD symptoms. Thankfully, following the procedure and calibration the patient exhibited marked improvements in their OCD symptoms and recently shared her results publicly.[xxx] In both cases, there is a similar level of abductive justification for the efficacy of the delivered therapy. In the case study in which the patient was treated with adaptive deep brain stimulation, they at least had their neural activity tested in various settings to determine the optimum parameters for treatment to avoid them being based on guesswork. Additionally, the adaptive deep brain stimulation lead was already placed before the calibration trials were conducted, meaning that the patient had already taken on the bulk of the procedural risk before the efficacy could be determined. Such an efficacy test could have been replicated in the first patient’s cancer treatment, had it been biopsied and tested against the remaining immunotherapies in vitro. Yet, in the case of cancer with few options, one previous dose of a drug that appeared to work on the patient may justify further doses. However, as the Norwegian case presents, corroboration with known responses to a similar drug (from a clinical trial) could be helpful to validate the treatment strategy. (It should be noted that both patients were resigned to these last resort options regardless of the efficacy of treatment.) There are some elements of inductive logic seen with adaptive deep brain stimulation research in general. For example, abductively the focus could be that patient X’s stimulation parameters are different from patient Y’s and patient Z’s. In contrast, when grouped as subjects who obtained personalized stimulation, patients X, Y, and Z demonstrate an inductive aspect to this approach’s safety and/or efficacy. The OCD case holds plenty of abductive characteristics in line with precision medicine’s approach to treating cancer and as more individuals try the method, there will be additional data. With the gradual integration of AI into brain-computer interfaces in the name of efficacy, this reliance on abduction will continue, if not grow, over time. Moving forward, if a responsive deep brain stimulation treatment is novel and individualized (like the dose of nivolumab) and there is some other suggestion of efficacy (like clinical similarities to other patients in the literature), then it may justify insurance coverage for the investigative intervention, absent other unrelated reasons to deny it. III. Ethical Implications and Next Steps While AI’s use in oncology and neurology is not yet as prominent as its use in other fields (e.g., radiology), it appears to be on the horizon for both.[xxxi] AI can be found in both the functioning of the neurotechnologies as well as the implementation of precision medicine. The increasing use of AI may serve to further individualize both oncologic and neurological therapies. Given these implications and the handful of publications cited in this article, it is important to have a nuanced evaluation of how these treatments, which heavily rely on abductive justification, ought to be managed. The just use an abductive approach may be difficult as AI infused precision medicine is further pursued. At baseline, such technology relies on a level of advanced technology literacy among the general public and could exclude populations who lack access to basic technological infrastructure or know-how from participation.[xxxii] Even among nations with adequate infrastructure, as more patients seek out implantable neurotechnologies, which require robust healthcare resources, the market will favor patient populations that can afford this complex care.[xxxiii] If patients already have the means to pay for an initial dose/use of a precision medicine product out of pocket, should insurance providers be required to cover subsequent treatments?[xxxiv] That is, if a first dose of a cancer drug or a deep brain stimulator over its initial battery life is successful, patients may feel justified in having the costs of further treatments covered. The Norwegian patient’s experience implies there is a precedent for the idea that some public insurance companies ought to cover successful cancer therapies, however, insurance companies may not all see themselves as obligated to cover neurotechnologies that rely on personalized settings or that are based on precision/abductive research more than on clinical trials. CONCLUSION The fact that the cases outlined above rely on abductive style of reasoning implies that there may not be as strong a justification for coverage by insurance, as they are both experimental and individualized, when compared to the more traditional large clinical trials in which groups have the same or a standardized protocol (settings/doses). If a study is examining the efficacy of a treatment with a large cohort of patients or with different experimental groups/phases, insurance companies may conclude that the resulting symptom improvements are more likely to be coming from the devices themselves. A preference for inductive justification may take priority when ruling in favor of funding someone’s continued use of an implantable neurostimulator. There are further nuances to this discussion surrounding the classifications of these interventions as research versus clinical care that warrant future exploration, since such a distinction is more of a scale[xxxv] than binary and could have significant impacts on the “right-to-try” approach to experimental therapies in the United States.[xxxvi] Namely, given the inherent limitations of conducting large cohort trials for deep brain stimulation interventions on patients with neuropsychiatric disorders, surgically innovative frameworks that blend abductive and inductive methodologies, like with sham stimulation phases, have traditionally been used.[xxxvii] Similarly, for adaptive brain-computer interface systems, if there are no large clinical trials and instead only publications that demonstrate that something similar worked for someone else, then, in addition to the evidence that the first treatment/dose worked for the patient in question, the balance of reasoning would be valid and arguably justify insurance coverage. As precision approaches to neurotechnology become more common, frameworks for evaluating efficacy will be crucial both for insurance coverage and for clinical decision making.

This article argues that — despite the value of distinguishing between insiders and outsiders in a contingent and relative sense — there is no fundamental insider—outsider problem. We distinguish weak and strong versions of 'insiderism' (privileged versus monopolistic access to knowledge) and then sociological and religious versions of the latter. After reviewing critiques of the sociological version, we offer a holistic semantic critique of the religious version (i.e. the view that religious experience and/or language offers sui (...) generis access to knowledge). We argue that all evidence for mental states is overt, public, and observable, and, hence, that there can be no significant difference in the access to knowledge of insiders and outsiders. (shrink)

The most skeptical contribution to this volume enumerates and discusses a broad set of challenges connected with the so-called human factor in a mission to Mars. Discussed issues include rationales for a human versus uncrewed mission, financial challenges affected mostly by unclear and weak rationales for human mission, challenges of sustainable development, complex hazardous impacts of space environment for human mental, and physiological health. The last of the discussed challenges, the idea of human enhancement applied for the purpose (...) of human deep-space missions, shows how technological issues—mostly long journey or ineffective countermeasures—might affect ethical concerns. While this idea might seem to be too far in the future, the chapter shows that it may be a serious and possibly unexpected long-term consequence of this program. This chapter does not determine whether a human mission to Mars is possible or not, nor whether such a mission makes any sense at all. One side of this chapter assumes that it is hard to find a strong rationale as measured in financial terms. The question of rationale is getting harder when a cost–benefit analysis—including risks for human health and life—is applied. On the other side, these skeptical remarks are designed to show that the idea of making humans a multi-planetary species is, in fact, extrapolation and projection of all problems and challenges known on Earth, which is intensified by putting Mars astronauts in the hazardous space environment.

Transhumanism aims to bring about radical human enhancement. In ‘Truly Human Enhancement’ Agar (2014) provides a strong argument against producing radically enhancing effects in agents. This leaves the transhumanist in a quandary—how to achieve radical enhancement whilst avoiding the problem of radically enhancing effects? This paper aims to show that transhumanism can overcome the worries of radically enhancing effects by instead pursuing radical human enhancement via incremental moderate human enhancements (Weak Transhumanism). In this sense, weak transhumanism (...) is much like traditional transhumanism in its aims, but starkly different in its execution. This version of transhumanism is weaker given the limitations brought about by having to avoid radically enhancing effects. I consider numerous objections to weak transhumanism and conclude that the account survives each one. This paper’s proposal of ‘weak transhumanism’ has the upshot of providing a way out of the ‘problem of radically enhancing effects’ for the transhumanist, but this comes at a cost—the restrictive process involved in applying multiple moderate enhancements in order to achieve radical enhancement will most likely be dissatisfying for the transhumanist, however, it is, I contend, the best option available.

This paper takes up the claim, made in some Buddhist texts, that one can transcend morality. The author distinguishes a weak and a strong sense in which this might be so, and explicates the strong sense in terms of Strawson's notion of presupposition.

Strong predictivism, the idea that novel predictions per se confirm theories more than accommodations, is based on a “no miracle” argument from novel predictions to the truth of theories (NMAT). Eric Barnes rejects both: he reconstructs the NMAT as seeking an explanation for the entailment relation between a theory and its novel consequences, and argues that it involves a fallacious application of Occam’s razor. However, he accepts a no miracle argument for the truth of background beliefs (NMABB): scientists endorsed (...) a successful theory because they were guided by largely true background beliefs. This in turn raises the probability that the theory is true; so Barnes embraces a form of weak predictivism, according to which predictions are only indirectly relevant to confirmation. To Barnes I reply that we should also explain how the successful theory was constructed, not just endorsed; background beliefs are not enough to explain success, scientific method must also be considered; Barnes can account for some measure of confirmation of our theories, but not for the practical certainty conferred to them by some astonishing predictions; true background beliefs and reliability by themselves cannot explain novel success, the truth of theories is also required. Hence, the NMAT is sound, and strong predictivism is right. In fact, Barnes misinterprets the NMAT, which does not involve Occam’s razor, takes as explanandum the building of a theory which turned out to predict surprising facts, and successfully concludes that the theory is true. This accounts for the practically certain confirmation of our most successful theories, in accordance with strong predictivism. (shrink)

This paper is about pairing relation algebras as well as fork algebras and related subjects. In the 1991-92 fork algebra papers it was conjectured that fork algebras admit a strong representation theorem . Then, this conjecture was disproved in the following sense: a strong representation theorem for all abstract fork algebras was proved to be impossible in most set theories including the usual one as well as most non-well-founded set theories. Here we show that the above quoted (...) conjecture can still be made true by choosing an appropriate set theory as our foundation of mathematics. Namely, we show that there are non-well-founded set theories in which every abstract fork algebra is representable in the strong sense, i.e. it is isomorphic to a set relation algebra having a fork operation which is obtained with the help of the real pairing function. Further, these non-well-founded set theories are consistent if usual set theory is consistent. Finally, we will discuss related developments in propositional multi-modal logics of quantification and substitution, in algebraic logic e.g. cylindric algebras, the so called finitization problem, and applications to a logic introduced and studied in Tarski-Givant [42]. In particular, representable, weakly higher order cylindric algebras are finitely axiomatizable in a set theory which admits the axiom of foundation for finite sets. (shrink)

A standard account of creativity is that it is a process in which the form of a thing or event is altered—restructured or reinterpreted—in a way that changes fundamentally that thing’s or event’s meaning, its nature or function, its intrinsic or instrumental value. What is created in this manner, however, is only a variation of the initial form. Such processes are creative in a weak sense; the strong sense requires that the old form be replaced by (...) a quite different one, as in reconstructions or metaphors. But creative substitution is not haphazard, not a matter of insight, genius, luck, or divine assistance. It utilizes the generative rules governing a formal structure to make or discover new forms that are transformations, not variations, of the original form. These procedures are teachable and not mysterious, although the possible transforms of the structure are never predictable. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 10.2 (2005) 5-27 [Access article in PDF] Environmental Epistemology Mark Rowlands 1. Externalism and Environmentalism There is a view of the mind that began life as a controversial philosophical thesis, and then, much like an aging rock group, evolved into respectability. Indeed, it became common sense. According to this view, minds are to be assimilated to the category of substance. That is, minds are (...) objects that possess properties. Indeed, minds can, to some extent, be conceived of as relatively similar to other bodily organs. Just as the heart circulates blood, the kidneys process waste, the mind thinks. According to the official version of this view, the major difference between the mind and these other organs is that the mind is a nonphysical substance. The brain and mind are, thus, distinct entities; the former a physical organ operating exclusively on mechanical principles, the latter a nonphysical organ operating according to principles of reason. The philosophical thesis from which this view was born was spelled out by Descartes, and its association with him is sufficiently robust for it to be called the Cartesian conception.The Cartesian conception has famously been ridiculed as the myth of the ghost in the machine. And it has been Descartes' decision to make the mind ghostly (i.e., nonphysical) that has drawn the principal fire from dissenters. The dissenters' case here has been largely successful, and, today, [End Page 5] not many would describe themselves as Cartesians in this sense. Ryle's expression, however, has another facet. Not only is the mind a ghost, but it is one that is in a machine. And while the revolt against ghostly views of the mind has been overwhelmingly successful, criticism of this second aspect of Descartes' view has, until recently, been comparatively muted. This changed with the development of a view that came to be known as externalism.The term 'externalism' in the philosophy of mind typically denotes a family of views, deriving from the work of Hilary Putnam (1975), Tyler Burge (1979, 1986), and certain work on indexicals associated, principally, with David Kaplan (1980), and all united by the idea that mental states, in some sense, are not in the head. Specifying the content of the clause in some sense, however, is no easy matter. Species and sub-species of externalism abound. Forms of externalism that assert the external location of mental states are contrasted with those that assert merely their external individuation (see, for example, McDowell 1986 and McGinn 1989 versus Macdonald 1990) Forms of externalism that admit a conceptually separable internally constituted component of mental states are contrasted with those that deny such a component. Weak externalism is commonly contrasted with strong, and one would look in vain for any unified construal of these qualifiers (contrast, for example, Forbes 1987, McGinn 1989, and Macdonald 1990).Nevertheless, for the purposes of this paper, externalism in all its forms, possesses two essential theses, one concerning the nature of the states to which the externalist thesis applies, and the other concerning the properties of those states in virtue of which it applies. The first thesis is that externalism applies only to the so-called propositional attitudes. It applies to beliefs, desires, hopes, fears, expectations, anticipations, and the like, all of which are (i) attributed to a subject by way of a that-clause, and (ii) are individuated, in part, by way of the proposition that follows this clause. The second thesis is that the externalist claim applies to such states because they possess semantic content; because they are individuated by way of the proposition that follows the that-clause.This means that the scope of externalism is severely restricted: it applies only to that relatively small group of mental states that have their contents essentially (i.e., propositional attitudes and possibly experiences—on some views of experience). What we might regard as the nuts [End Page 6] and bolts of cognition, processes, such as perceiving, remembering, thinking, reasoning, whereby we arrive at, or come to have, propositional attitudes, these are left outside the scope of externalism. That is, externalism as it is commonly understood, is... (shrink)

In debate with John Caiazza, we clarify the meaning of the terms technology and secular, arguing that technology is not really secular. Only when combined with antireligious secularism do we get the modern techno‐secular worldview. Science is not secular in the strong sense, nor does its practice automatically lead to the techno‐secular. As a complete worldview, techno‐secularism is antireligious, but it also is dehumanizing and destructive of our environment. Religion may provide a transcendent source for a humanizing morality (...) that might move technology in a more ecofriendly, humane direction. The alternative is not a happy one for our posthuman technological future. (shrink)

Reverse inference is a crucial inferential strategy used in cognitive neuroscience to derive conclusions about the engagement of cognitive processes from patterns of brain activation. While widely employed in experimental studies, it is now viewed with increasing scepticism within the neuroscience community. One problem with reverse inference is that it is logically invalid, being an instance of abduction in Peirce’s sense. In this paper, we offer the first systematic analysis of reverse inference as a form of abductive reasoning and (...) highlight some relevant implications for the current debate. We start by formalising an important distinction that has been entirely neglected in the literature, namely the distinction between weak and strong reverse inference. Then, we rely on case studies from recent neuroscientific research to systematically discuss the role and limits of both strong and weak reverse inference; in particular, we offer the first exploration of weak reverse inference as a discovery strategy within cognitive neuroscience.

Is it OK to lie to Siri? Is it bad to mistreat a robot for our own pleasure? Under what condition should we grant a moral status to an artificial intelligence system? This paper looks at different arguments for granting moral status to an AI system: the idea of indirect duties, the relational argument, the argument from intelligence, the arguments from life and information, and the argument from sentience. In each but the last case, we find unresolved issues with the (...) particular argument, which leads us to move to a different one. We leave the idea of indirect duties aside since these duties do not imply considering an AI system for its own sake. The paper rejects the relational argument and the argument from intelligence. The argument from life may lead us to grant a moral status to an AI system, but only in a weak sense. Sentience, by contrast, is a strong argument for the moral status of an AI system—based, among other things, on the Aristotelian principle of equality: that same cases should be treated in the same way. The paper points out, however, that no AI system is sentient given the current level of technological development. (shrink)

Quantum mechanical weak values of projection operators have been used to answer which-way questions, e.g. to trace which arms in a multiple Mach–Zehnder setup a particle may have traversed from a given initial to a prescribed final state. I show that this procedure might lead to logical inconsistencies in the sense that different methods used to answer composite questions, like “Has the particle traversed the way X or the way Y?”, may result in different answers depending on which (...) methods are used to find the answer. I illustrate the problem by considering some examples: the “quantum pigeonhole” framework of Aharonov et al., the three-box problem, and Hardy’s paradox. To prepare the ground for my main conclusion on the incompatibility in certain cases of weak values and logic, I study the corresponding situation for strong/projective measurements. In this case, no logical inconsistencies occur provided one is always careful in specifying exactly to which ensemble or sample space one refers. My results cast doubts on the utility of quantum weak values in treating cases like the examples mentioned. (shrink)

For a given inner model N of ZFC, one can consider the relativized version of Berkeley cardinals in the context of ZFC, and ask if there can exist an “N-Berkeley cardinal.” In this article we provide a positive answer to this question. Indeed, under the assumption of a supercompact cardinal $\delta $, we show that there exists a ZFC inner model N such that there is a cardinal which is N-Berkeley, even in a strong sense. Further, the involved (...) model N is a weak extender model of $\delta $ is supercompact. Finally, we prove that the strong version of N-Berkeley cardinals turns out to be inconsistent whenever N satisfies closure under $\omega $ -sequences. (shrink)

Structuring Sense explores the difference between words however defined and structures however constructed. It sets out to demonstrate over three volumes, of which this is the first, that the explanation of linguistic competence should be shifted from lexical entry to syntactic structure, from memory of words to manipulation of rules. Its reformulation of how grammar and lexicon interact has profound implications for linguistic, philosophical, and psychological theories about human mind and language. Hagit Borer departs from both language specific constructional (...) approaches and lexicalist approaches to argue that universal hierarchical structures determine interpretation, and that language variation emerges from the morphological and phonological properties of inflectional material. In Name Only applies this radical approach to nominal structure. Integrating research in syntax, semantics, and morphology, the author argues that nominal structure is based on the syntactic realization of semantic notions such as classifier, quantity, and reference. In the process she seeks to do away with lexical ambiguity and type-shifting. Among the topics she considers are the interpretation of proper names, the mass-count distinction, the weak-strong interpretation of quantifiers, partitive and measure phrases, and the structural representation of the definite article. In the process she explores inter-language variation through the properties of the morpho-phonological system. The languages discussed include English, Chinese, Italian, and Hebrew. (shrink)

In three experiments, we investigated the computational complexity of German reciprocal sentences with different quantificational antecedents. Building upon the tractable cognition thesis (van Rooij, 2008) and its application to the verification of quantifiers (Szymanik, 2010) we predicted complexity differences among these sentences. Reciprocals with all-antecedents are expected to preferably receive a strong interpretation (Dalrymple et al., 1998), but reciprocals with proportional or numerical quantifier antecedents should be interpreted weakly. Experiment 1, where participants completed pictures according to their preferred interpretation, (...) provides evidence for these predictions. Experiment 2 was a picture verification task. The results show that the strong interpretation was in fact possible for tractable all but one-reciprocals, but not for exactly n. The last experiment manipulated monotonicity of the quantifier antecedents. (shrink)

In this contribution, we draw on findings from a non-formal, community music project to elaborate on the relationship between the concept ofeudaimonia, as defined by Seligman, the interactive dimensions of collective free improvisation, and the concept of collaborative creativity. The project revolves around The Ostend Street Orkestra (TOSO), a music ensemble within which homeless adults and individuals with a psychiatric or alcohol/drug related background engage in collective musical improvisation. Between 2017 and 2019 data was collected through open interviews and video (...) recordings of rehearsals and performances. Participant data was analyzed through inductive analysis based on the principles of grounded theory. One interesting finding was the discrepancy in the participant interviews between social relationships indicative of a negative affect about social group interaction versus strong feelings of group coherence and belonging. Video recordings of performances and rehearsals showed clear enjoyment and pleasure while playing music. Alongside verbal reflection through one-on-one interviews video recordings and analysis of moment-to moment observations should be used, in order to capture the complexity of community music projects with homeless people. The initial open coding was aligned with the five elements of the PERMA model. Overall, we observed more focus on Relationship (sense of belonging), Engagement (flow in rehearsals and performances) and Meaning (belonging to something greater than yourself) and less on Positive Emotion and Accomplishment (goal setting).

The goal of the present study was to investigate whether children’s cognitive strengths can compensate the accompanied weaknesses related to their specific learning difficulties. A Bayesian multigroup mediation SEM analysis in 281 fourth-grade children identified a cognitive compensatory mechanism in children with mathematical learning difficulties (n= 36): Children with weak number sense, but strong rapid naming performed slightly better on mathematics compared to peers with weak rapid naming. In contrast, a compensatory mechanism was not identified for (...) children with a comorbid mathematical and reading difficulty (n= 16). One explanation for the latter finding could relate to the lack of ability to compensate, because of the difficulties these children experience in both academic domains. These findings lead to a new direction in research on learning difficulties in mathematics and/or reading by suggesting that children with a learning disability each have a unique profile of interrelated cognitive strengths and weaknesses. Children might compensate with these strengths for their weaknesses, which could lead to (small) learning gains in the affected domain. (shrink)

In an influential recent paper, Hawthorne, Rothschild, and Spectre (“HRS”) argue that belief is weak. More precisely: they argue that the referent of believe in ordinary language is much weaker than epistemologists usually suppose; that one needs very little evidence to be entitled to believe a proposition in this sense; and that the referent of believe in ordinary language just is the ordinary concept of belief. I argue here to the contrary. HRS identify two alleged tests of weakness (...) – the neg-raising and weak upper bounds tests, as I call them – which they claim believe and think pass. But I identify several other expressions in ordinary English for attributing belief, all of which fail both tests. Therefore, even if HRS are correct that believe and think refer to a weak attitude, it does not follow that the ordinary concept of belief is weak. I conclude by raising some problems for the accounts of belief as guessing, building on HRS's arguments, due to Kevin Dorst, Matt Mandelkern, and Ben Holguín. (shrink)

This paper addresses the question: Who or what can have a moral status in the sense that we have direct moral duties to them? It argues for a biocentric answer which ascribes inherent moral status value to all individual living organisms. This position must be defended against an anthropocentric position. The argument from marginal cases propounded by Tom Regan and Peter Singer for this purpose is criticised as defective, and a different argument is proposed. The biocentric position developed here (...) is related to that of Albert Schweitzer and Paul F. Taylor, but rejects their assumption of equal inherent value for all living organisms. It argues instead for equal moral status value for moral persons and agents, and gradual moral status value for nonpersons, depending on their degree of similarity with moral persons. Mary Ann Warren's recent book on Moral Status is also discussed. The argument is constructed as a casuistic argument, proceeding by analogical extension from persons to non-persons. The meta-ethical question of its pragmatic validity is discussed. (shrink)

In this paper we study a reducibility that has been introduced by Klaus Weihrauch or, more precisely, a natural extension for multi-valued functions on represented spaces. We call the corresponding equivalence classes Weihrauch degrees and we show that the corresponding partial order induces a lower semi-lattice. It turns out that parallelization is a closure operator for this semi-lattice and that the parallelized Weihrauch degrees even form a lattice into which the Medvedev lattice and the Turing degrees can be embedded. The (...) importance of Weihrauch degrees is based on the fact that multi-valued functions on represented spaces can be considered as realizers of mathematical theorems in a very natural way and studying the Weihrauch reductions between theorems in this sense means to ask which theorems can be transformed continuously or computably into each other. As crucial corner points of this classification scheme the limited principle of omniscience LPO, the lesser limited principle of omniscience LLPO and their parallelizations are studied. It is proved that parallelized LLPO is equivalent to Weak Kőnig's Lemma and hence to the Hahn—Banach Theorem in this new and very strong sense. We call a multi-valued function weakly computable if it is reducible to the Weihrauch degree of parallelized LLPO and we present a new proof, based on a computational version of Kleene's ternary logic, that the class of weakly computable operations is closed under composition. Moreover, weakly computable operations on computable metric spaces are characterized as operations that admit upper semi-computable compact-valued selectors and it is proved that any single-valued weakly computable operation is already computable in the ordinary sense.

In this paper we focus on some new normativist positions and compare them with traditional ones. In so doing, we claim that if normative judgments are involved in determining whether a condition is a disease only in the sense identified by new normativisms, then disease is normative only in a weak sense, which must be distinguished from the strong sense advocated by traditional normativisms. Specifically, we argue that weak and strong normativity are different (...) to the point that one ‘normativist’ label ceases to be appropriate for the whole range of positions. If values and norms are not explicit components of the concept of disease, but only intervene in other explanatory roles, then the concept of disease is no more value-laden than many other scientific concepts, or even any other scientific concept. We call the newly identified position “value-conscious naturalism” about disease, and point to some of its theoretical and practical advantages. (shrink)

In our daily lives we conceive of our surroundings as an objectively given reality. The world is perceived through our senses, and ~hese provide us, so we believe, with a faithful image of the world. But occ~ipnally we are forced to realize that our senses deceive us, e. g., by illusions. For a while it was believed that the sensation of color is directly r~lated to the frequency of light waves, until E. Land (the inventor of the polaroid camera) showed (...) in detailed experiments that our perception of, say, a colored spot depends on the colors of its surrounding. On the other hand, we may experience hallucinations or dreams as real. Quite evidently, the relationship between the "world" and our "brain" is intricate. Another strange problem is the way in which we perceive time or the "Now". Psychophysical experiments tell us that the psychological "Now" is an extended period of time in the sense of physics. The situation was made still more puzzling when, in the nineteen-twenties, Heisenberg and others realized that, by observing processes in the microscopic world of electrons and other elementary particles, we strongly interfere with that world. The outcome of experiments - at least in general - can only be predicted statistically. What is the nature ofthis strange relationship between "object" and "observer"? This is another crucial problem of the inside-outside or endo-exo dichotomy. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Problems with a Weakly Pluralist Approach to Democratic EducationSheron Fraser-BurgessIntroductionPluralism embodies wide acknowledgement of various forms of difference. Appeals to pluralism involve arguments for the proliferating of differences as a social and moral ideal. Rather than being a formal political regime such as with democracy or social liberalism, in the extant political philosophy literature, pluralism brings considerations of diversity and equality to bear in philosophical analysis of traditional systems (...) of government.As a critique, pluralism falls along a continuum, which can be conceived of as iterations of the standing of particular ways of life, with respect to constraints of both equality and justice. At one end of the spectrum, all conceptions of the human good share a prima facie equality that belie overarching moral norms as a criterion of ranking. Questions about the incumbency of individual liberty motivate movement toward the opposing end, as allowing for the most just society warrants giving precedence to such values. The source of pluralism’s critical role is its inherent demand of a cogent resolution of the moral and, at times, political tension between equality and freedom.This article considers two forms of pluralism that lie near opposing extremes of the continuum and their implication for education. According to Horace Kallen’s and John Gray’s strong pluralism, the claim to the fact of differing values, cultures, etc., has primacy. As a corollary, maintaining the integrity of the social groups as holders of those values becomes central. In conflict with liberal democratic principles, however, protecting group values may occur at the expense of individual detractors within the group or may pose a threat of harm to others outside of the group who do not share these values.On the other hand, one form of weak pluralism, Amy Gutmann’s deliberative democracy, constrains pluralism on political grounds of individual [End Page 1] freedom. Deliberative democracy subsumes the holding of all values, including those shared with a social group, to the requirements of democracy. Both theories are considered as attempts to reconcile principles of treating everyone equally with not unjustly limiting individual freedom in a democracy. I raise principled and practical issues from education that call into question whether each theory satisfactorily resolves the conflicting demands of both equality and liberty. A third alternative is proposed as a salient consideration for democratic education. I begin with the pluralism of Horace Kallen and its relationship to that of John Gray.Strong PluralismHorace Kallen’s Cultural PluralismIn this section, I discuss Horace Kallen’s seminal account of cultural pluralism from the early twentieth century, classifying it with the strong value pluralism articulated by John Gray. Gray’s and Kallen’s pluralism have in common both the sanctioning of the fullest expression of difference and difficulties with making sense of the intuitive pull toward a criterion for the ranking of values that democracy dictates. I then consider the educational implications of Kallen’s view, particularly with respect to its actual influence upon multi-cultural initiatives of the 1970s and 1980s.Kallen coined the term “cultural pluralism” in the early twentieth century (Kallen 73). At this time, America was experiencing a great deal of social upheaval because of the huge influx of European and Asian immigrants. Movements such as nativism and Americanization fueled xenophobic sentiment. In this milieu, the full acculturation of new immigrants became a priority. In education, schooling policies penalized immigrant expressions of cultural identity, such as speaking one’s native language and practicing cultural traditions (Kallen 4).Kallen was one of the voices advocating not only that new immigrants should be allowed to maintain their cultural identity but also that a formal political solution be initiated which accommodated the predilection to do so. Nathan Glazer explains that there was at that time a general blindness to the possibility that “these groups or elements within them would not want to acculturate and assimilate but would want to preserve their corporate characters and distinctiveness even if prejudice and discrimination disappeared.” According to Glazer, such was the doctrine of assimilation for the first forty years of the twentieth century (7).

In this contribution, Sharon Todd moves beyond the bounds of what she calls “strong” instrumentalism (one that posits education in a mechanistic fashion and operates politically through a marrying of national educational policies with economic interests) and explores the intrinsic purpose of educational practice specifically through an aesthetic lens. Todd considers how two art projects by the feminist art collective Sisters Hope offer a way of theorizing instrumentalism in a “weak” sense — that is, an instrumentalism that (...) sees pedagogical practices not in terms of social function, but as that which gives form to specifically educational (not social or economic) ideas. She does this by drawing parallels between education and art as fields of practice, informed by notions of experience, relation, and formation/transformation. Drawing on John Dewey's aesthetics and Nicolas Bourriaud's relational aesthetics, Todd argues how these notions are central to an understanding of “weak” instrumentalism in education. (shrink)

In three experiments, we investigated the computational complexity of German reciprocal sentences with different quantificational antecedents. Building upon the tractable cognition thesis (van Rooij, 2008) and its application to the verification of quantifiers (Szymanik, 2010) we predicted complexity differences among these sentences. Reciprocals with all-antecedents are expected to preferably receive a strong interpretation (Dalrymple et al., 1998), but reciprocals with proportional or numerical quantifier antecedents should be interpreted weakly. Experiment 1, where participants completed pictures according to their preferred interpretation, (...) provides evidence for these predictions. Experiment 2 was a picture verification task. The results show that the strong interpretation was in fact possible for tractable all but one-reciprocals, but not for exactly n. The last experiment manipulated monotonicity of the quantifier antecedents. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Folk Taxonomies Versus Official TaxonomiesNick Haslam (bio)Keywordsclassification, DSM-IV, folk taxonomyFlanagan and Blashfield’s paper continues a highly original program of research on clinicians’ understandings of psychopathology. This work is unique in bringing concepts and methods from cognitive anthropology to bear on psychiatric classification. At first blush, it might seem questionable to treat clinicians’ beliefs about psychiatric disorders as folk taxonomies, no different in kind from classifications of birds produced (...) by members of a forest-dwelling tribe. Unlike birds and other natural objects of folk taxonomies, mental disorders are not concrete entities and they cannot be distinguished on perceptual grounds. Unlike tribespeople, clinicians are not simply “folk” whose naïve classifications can be compared with those of scientific authorities. They are, in fact, heavily exposed to the reigning official taxonomy during their professional training, and their thinking can hardly remain unaffected by it. It is a testament to Flanagan and Blashfield’s work that despite these apparent disanalogies, their folk-taxonomic approach manages to illuminate how clinicians carve up the psychiatric domain.This paper reports some careful, creative, and labor-intensive studies to make a few fundamental claims about how clinicians classify. First, the authors argue that clinicians hold simplified taxonomies compared with the official DSM-IV taxonomy: They encompass fewer disorders and classify them in a shallower hierarchy. Second, they claim that clinicians substantially agree in how they classify disorders, and that a consensus classification can therefore be extracted from their individual taxonomies. Third, they argue that clinicians’ taxonomies show only a modest consistency with DSM-IV, and that the discrepancies may be systematic and important. Notably, for example, clinicians did not preserve the fundamental divide between the DSM’s Axes I and II. My comments address the second and third claims.Is There a “Consensus” among the Clinicians?One of the main achievements of Flanagan and Blashfield’s paper is to develop a “consensual taxonomy,” which is laid out in their Table 2a. This taxonomy clearly distils how their clinicians tended to judge the relations among diagnoses. However, it is an exaggeration to present it as a consensus. If, by Romney, Weller, and Batchelder’s (1986) third criterion, “cultural consensus” requires that the primary factor in a principal components analysis accounts for “most” of the variance in clinicians’ judgments, then Flanagan and Blashfield’s analysis [End Page 281] fails to show consensus. Their first factor accounts for only twenty-five percent of the variance, well short of the required majority. This finding implies that there is three times as much inconsistency or variability among clinicians’ taxonomic judgments than there is consistency and commonality. The observed factor-analytic findings are compatible with the average correlation between pairs of clinicians being only about 0.2, a very weak level of agreement.This is not to say that there is no consistency among the clinicians, or that there is no value in summarizing that consistency, but it does indicate that there is a great deal of diversity as well. Clinicians’ folk taxonomies seem to be highly idiosyncratic, more a Babel of distinctive classifications than a chorus of agreement. It is therefore risky to draw strong generalizations about how clinicians classify, and to imply that there is a single consensual taxonomy.Several things are very interesting about this diversity of classifications. First, Flanagan and Blashfield show that it cannot be explained by the clinicians’ differing levels of experience or by the different methodologies used to elicit their taxonomies. The variability among clinicians must therefore have some other basis, which awaits further investigation. Second, the level of agreement (“consensus”) obtained here is significantly lower than what has been found in more orthodox studies of folk taxonomy. By implication, the classification of psychiatric disorders is a slipperier enterprise than the classification of animals and plants. People who have extensive professional experience and training in the field of psychopathology—vocational training that includes the standardizing forces of accrediting bodies and a dominant psychiatric nosology—nevertheless tend not to agree substantially about how to map that territory. One guess about why this might be is that clinicians’ folk taxonomies are not merely descriptive maps of the interrelations among diagnostic entities, but are... (shrink)

We give several characterizations of weakly minimal abelian structures. In two special cases, dual in a sense to be made explicit below, we give precise structure theorems: 1. When the only finite 0-definable subgroup is {0}, or equivalently 0 is the only algebraic element (the co-strongly minimal case); 2. When the theory of the structure is strongly minimal. In the first case, we identify the abelian structure as a "near-subspace" A of a vector space V over a division ring (...) D with its induced structure, with possibly some collection of distinguished subgroups of A of finite index in A and (up to $acl(\emptyset)$ ) no further structure. In the second, the structure is that of V/A for a vector space and near-subspace as above, with the only further possible structure some collection of distinguished points. Here a near-subspace of V is a subgroup A such that for any nonzero d ∈ D, the index of $A\cap dA$ in A is finite. We also show that any weakly minimal abelian structure is a reduct of a weakly minimal module. (shrink)
