Philosophy and model theory frequently meet one another. Philosophy and Model Theory aims to understand their interactions -/- Model theory is used in every ‘theoretical’ branch of analytic philosophy: in philosophy of mathematics, in philosophy of science, in philosophy of language, in philosophical logic, and in metaphysics. But these wide-ranging appeals to model theory have created a highly fragmented literature. On the one hand, many philosophically significant mathematical results are found only in mathematics textbooks: these are aimed squarely at mathematicians; (...) they typically presuppose that the reader has a significant background in mathematics; and little clue is given as to their philosophical significance. On the other hand, the philosophical applications of these results are then scattered across disconnected pockets of papers, separated by decades or more. -/- The first aim of Philosophy and Model Theory, then, is to consider the philosophical uses of model theory. On a technical level, we try to show how philosophically significant results connect to one another, and also to state the best version of a result for philosophical purposes. On a philosophical level, we show how similar dialectical situations arise repeatedly, across fragmented debates in varied philosophical areas. -/- The second aim of Philosophy and Model Theory, though, is to consider the philosophy of model theory. Model theory itself is rarely taken as the subject matter of philosophising (contrast this, say, with the philosophy of biology, or the philosophy of set theory). But model theory is a beautiful part of pure mathematics, and worthy of philosophical study in its own right. (shrink)

This article argues that, in De Trinitate, Augustine’s ascent to God via a search for the Trinity is successful precisely because of the emphasis he places on the role of Christ in such an ascent. Unlike scholarship which reads this ascent as an exercise in Neoplatonism—whether as a success or as an intentional failure—this article asserts that Augustine successfully discovers an imago trinitatis in human beings by identifying the essential mediation of the temporal and eternal in the person of the (...) Incarnate Word. Of the work’s fifteen books, Books 4 and 13 focus extensively on the soteriological and epistemological role of Christ, who, in his humility, conquered the pride of the devil and reopened humanity’s way to eternity. The Christology in these books plays an important role in Augustine’s argument by allowing his ascent to move from self-knowledge to contemplation of God. Indeed, it is his understanding of the Christological perfection of the imago dei which allows Augustine to discover a genuine imago trinitatis in human beings. For Augustine, the imago is observable in humanity to the extent that an individual is conformed to Christ, the perfect image of the invisible God. Thus, it is only through Christ that a human being can successfully contemplate the Trinity in this imago. (shrink)

Awe arises when one experiences something so extraordinary that it defies current understanding, prompting efforts to comprehend the initially incomprehensible. We situate awe within Dubourg and Baumard's framework for the prevalence and psychological underpinnings of imaginary worlds. We argue that imaginary worlds are powerful catalysts of awe, which, in turn, drive important individual and social outcomes.

We discuss three varieties of affective dynamics. In each case, we suggest how these affective dynamics should be operationalized and measured in daily life using time-intensive methods, like ecological momentary assessment or ambulatory assessment, and recommend time-sensitive analyses that take into account not only the variability but also the temporal dependency of reports. Studies that explore how these affective dynamics are associated with psychological disorders and symptoms are reviewed, and we emphasize that these affective processes are within a nexus of (...) other components of emotion regulation.

Genetic variability is considered a key to the evolvability of species. The conversion of an adenosine (A) to inosine (I) in primary RNA transcripts can result in an amino acid change in the encoded protein, a change in secondary structure of the RNA, creation or destruction of a splice consensus site, or otherwise alter RNA fate. Substantial transcriptome and proteome variability is generated by A‐to‐I RNA editing through site‐selective post‐transcriptional recoding of single nucleotides. We posit that this epigenetic source of (...) phenotypic variation is an unrecognized mechanism of adaptive evolution. The genetic variation introduced through editing occurs at low evolutionary cost since predominant production of the wild‐type protein is retained. This property even allows exploration of sequence space that is inaccessible through mutation, leading to increased phenotypic plasticity and provides an evolutionary advantage for acclimatization as well as long‐term adaptation. Furthermore, continuous probing for novel RNA editing sites throughout the transcriptome is an intrinsic property of the editing machinery and represents the molecular basis for increased adaptability. We propose that higher organisms have therefore evolved to systems with increasing RNA editing activity and, as a result, to more complex systems. (shrink)

Roommate relationships are fundamental to the social environment of many emerging adults. However, no validated, widely used, measure of roommate relationship quality exists for examining the impact of these relationships on individual functioning and health. In this report, we present preliminary evidence of the factor structure, concurrent validity, and construct validity of the Roommate Relationship Scale as a measure of roommate relationship quality using a sample of U.S. college students who participated in a multi-wave study. An exploratory factor analysis at (...) the first wave, and confirmatory factor analyses with independent samples of new participants at each of two subsequent waves showed stable factor loadings and adequate fit. Moreover, the scale demonstrated good fit and reliability in a longitudinal multilevel CFA framework. The RRS significantly positively correlated with relationship length, self-esteem, extraversion, agreeableness, and conscientiousness, and negatively correlated with symptoms of anxiety and avoidant attachment style, indicating concurrent validity of the scale with respect to these constructs. Consistent with findings from other relationship types, self-reported RRS scores decrease longitudinally, both across and between semesters of academic life, indicating construct validity of the scale. We conclude that the RRS is useful for evaluating roommate relationship quality among U.S. college students, and hopefully beyond. Further research should validate the scale’s utility in other, more diverse, populations and refine its underlying generating psychological process. (shrink)

Graphical AbstractA recent study reported that longevity in Caenorhabditits elegans can be inherited over several generations. This is probably achieved through the following epigenetic mechanism: inherited demethylated histones at some central loci, such as miRNA, transcription factors or signaling regulators affect the expression of certain genes leading to the longevity phenotype.

BackgroundKinarm Standard Tests is a suite of upper limb tasks to assess sensory, motor, and cognitive functions, which produces granular performance data that reflect spatial and temporal aspects of behavior. We have previously used principal component analysis to reduce the dimensionality of multivariate data using the Kinarm End-Point Lab. Here, we performed PCA using data from the Kinarm Exoskeleton Lab, and determined agreement of PCA results across EP and EXO platforms in healthy participants. We additionally examined whether further dimensionality reduction (...) was possible by using PCA across behavioral tasks.MethodsHealthy participants were assessed using the Kinarm EXO and EP. Four behavioral tasks were performed that quantified arm sensory and motor function, including position sense [Arm Position Matching ] and three motor tasks [Visually Guided Reaching, Object Hit, and Object Hit and Avoid ]. The number of components to include per task was determined from scree plots and parallel analysis, and rotation type was decided on a per-task basis. To assess agreement, we compared principal components across platforms using distance correlation. We additionally considered inter-task interactions in EXO data by performing PCA across all six behavioral assessments.ResultsBy applying PCA on a per task basis to data collected using the EXO, the number of behavioral parameters were substantially reduced by 58–75% while accounting for 76–87% of the variance. These results compared well to the EP analysis, and we found good-to-excellent agreement values between PCs from the EXO and those from the EP. Finally, we were able to reduce the dimensionality of the EXO data across tasks down to 16 components out of a total of 76 behavioral parameters, which represents a reduction of 79% while accounting for 73% of the total variance.ConclusionPCA of Kinarm robotic assessment appears to capture similar relationships between kinematic features in healthy individuals and is agnostic to the robotic platform used for collection. Further work is needed to investigate the use of PCA-based data reduction for the characterization of neurological deficits in clinical populations. (shrink)

Magnetic resonance imaging (MRI) can provide a number of measurements relevant to sport-related concussion (SRC) symptoms; however, most studies to date have used a single MRI modality and whole-brain exploratory analyses in attempts to localize concussion injury. This has resulted in highly variable findings across studies due to wide ranging symptomology, severity and nature of injury within studies. A multimodal MRI, symptom-guided region-of-interest (ROI) approach is likely to yield more consistent results. The functions of the cerebellum and basal ganglia transcend (...) many common concussion symptoms, and thus these regions, plus the white matter tracts that connect or project from them, constitute plausible ROIs for MRI analysis. We performed diffusion tensor imaging (DTI), resting-state functional MRI, quantitative susceptibility mapping (QSM), and cerebral blood flow (CBF) imaging using arterial spin labeling (ASL), in youth aged 12-18 years following SRC, with a focus on the cerebellum, basal ganglia and white matter tracts. Compared to controls similar in age, sex and sport (N = 20), recent SRC youth (N = 29; MRI at 8 ± 3 days post injury) exhibited increased susceptibility in the cerebellum (p = 0.032), decreased functional connectivity between the caudate and each of the pallidum (p = 0.035) and thalamus (p = 0.021), and decreased diffusivity in the mid-posterior corpus callosum (p < 0.038); no changes were observed in recovered asymptomatic youth (N = 16; 41 ± 16 days post injury). For recent symptomatic-only SRC youth (N = 24), symptom severity was associated with increased susceptibility in the superior cerebellar peduncles (p = 0.011) and reduced activity in the cerebellum (p = 0.013). Fewer days between injury and MRI were associated with reduced cerebellar-parietal functional connectivity (p < 0.014), reduced activity of the pallidum (p = 0.002), increased CBF in the caudate (p = 0.005), and reduced diffusivity in the central corpus callosum (p < 0.05). Youth SRC is associated with acute cerebellar inflammation accompanied by reduced cerebellar activity and cerebellar-parietal connectivity, as well as structural changes of the middle regions of the corpus callosum accompanied by functional changes of the caudate, all of which resolve with recovery. Early MRI post-injury is important to establish objective MRI-based indicators for concussion diagnosis, recovery assessment and prediction of outcome. (shrink)

On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...) duration is still regarded as relative, but temporal succession is taken to be absolute. Following our approach, which is presented in more formal terms in, it is possible to conceive of a genuinely dynamical theory of quantum gravity within which time, in a substantive sense, remains. 1 Introduction1.1 The problem of time1.2 Our solution2 Understanding Symmetry2.1 Mechanics and representation2.2 Freedom by degrees2.3 Voluntary redundancy3 Understanding Time3.1 Change and order3.2 Quantization and succession4 Time and Gravitation4.1 The two faces of classical gravity4.2 Retaining succession in quantum gravity5 Discussion5.1 Related arguments5.2 Concluding remarks.

A novel approach to quantization is shown to allow for superpositions of the cosmological constant in isotropic and homogeneous mini-superspace models. Generic solutions featuring such superpositions display: i) a unitary evolution equation; ii) singularity resolution; iii) a cosmic bounce. Explicit cosmological solutions are constructed. These exhibit characteristic bounce features including a ‘super-inflation’ regime with universal phenomenology that can naturally be made to be insensitive to Planck-scale physics.

A companion paper provides a proposal for cosmic singularity resolution based upon general features of a bouncing unitary cosmological model in the mini-superspace approximation. This paper analyses novel phenomenology that can be identified within particular solutions of that model. First, we justify our choice of particular solutions based upon a clearly articulated and observationally-motivated principle. Second, we demonstrate that the chosen solutions follow a classical mini-superspace cosmology before smoothly bouncing off the classically singular region. Third, and most significantly, we identify (...) a 'Rayleigh-scattering' limit for physically reasonable choices of parameters within which the solutions display effective behaviour that is insensitive to the details of rapidly oscillating Planck-scale physics. This effective physics is found to be compatible with an effective period of cosmic inflation well below the Planck scale. The detailed effective physics of this Rayleigh-scattering limit is provided via: i) an exact analytical treatment of the model in the de Sitter limit; and ii) numerical solutions of the full model.

Starting from a generalized Hamilton-Jacobi formalism, we develop a new framework for constructing observables and their evolution in theories invariant under global time reparametrizations. Our proposal relaxes the usual Dirac prescription for the observables of a totally constrained system and allows one to recover the influential partial and complete observables approach in a particular limit. Difficulties such as the non-unitary evolution of the complete observables in terms of certain partial observables are explained as a breakdown of this limit. Identification of (...) our observables relies upon a physical distinction between gauge symmetries that exist at the level of histories and states, and those that exist at the level of histories and not states. This distinction resolves a tension in the literature concerning the physical interpretation of the partial observables and allows for a richer class of observables in the quantum theory. There is the potential for the application of our proposal to the quantization of gravity when understood in terms of the Shape Dynamics formalism. (shrink)

A physically consistent semi-classical treatment of black holes requires universality arguments to deal with the ‘trans-Planckian’ problem where quantum spacetime effects appear to be amplified such that they undermine the entire semi-classical modelling framework. We evaluate three families of such arguments in comparison with Wilsonian renormalization group universality arguments found in the context of condensed matter physics. Our analysis is framed by the crucial distinction between robustness and universality. Particular emphasis is placed on the quality whereby the various arguments are (...) underpinned by ‘integrated’ notions of robustness and universality. Whereas the principal strength of Wilsonian universality arguments can be understood in terms of the presence of such integration, the principal weakness of all three universality arguments for Hawking radiation is its absence.

Employee attitudes to change are key predictors of organizational change success. In this article, change engagement is defined as the extent to which employees are enthusiastic about change, and willing to actively involve themselves in ongoing organizational change. A model is tested showing how change-related organizational resources influence change engagement, in part through their influence on change-related job resources. Confirmatory Factor Analysis and Structural Equations Modeling results yielded good fit to the data in two independent samples: 225 Australian working professionals, (...) and 201 employees from a Prolific sample. As proposed, change-related organizational resources were positively associated with higher order change-related job resources. Change-related job resources were positively associated with change engagement. In contrast to expectations, organizational resources were not directly associated with change engagement. Instead, change-related job resources fully mediated the relationship. Overall, the study provides empirical support for new measures of organizational change resources and employee change engagement. By drawing from well-established models in the change and engagement literatures, the study provides a promising research direction for those interested in further understanding positive employee attitudes to organizational change. Practical implications and future research opportunities are discussed. (shrink)

The canonical formalism of general relativity affords a particularly interesting characterisation of the infamous hole argument. It also provides a natural formalism in which to relate the hole argument to the problem of time in classical and quantum gravity. In this paper we examine the connection between these two much discussed problems in the foundations of spacetime theory along two interrelated lines. First, from a formal perspective, we consider the extent to which the two problems can and cannot be precisely (...) and distinctly characterised. Second, from a philosophical perspective, we consider the implications of various responses to the problems, with a particular focus upon the viability of a `deflationary' attitude to the relationalist/substantivalist debate regarding the ontology of spacetime. Conceptual and formal inadequacies within the representative language of canonical gravity will be shown to be at the heart of both the canonical hole argument and the problem of time. Interesting and fruitful work at the interface of physics and philosophy relates to the challenge of resolving such inadequacies. (shrink)

A widespread perception is that carnivores are limited by the amount of prey that can be captured rather than their nutritional quality, and thus have no need to regulate macronutrient balance. Contrary to this view, recent laboratory studies show macronutrient‐specific food selection by both invertebrate and vertebrate predators, and in some cases also associated performance benefits. The question thus arises of whether wild predators might likewise feed selectively according to the macronutrient content of prey. Here we review laboratory studies demonstrating (...) the regulation of macronutrient intake by invertebrate and vertebrate predators, and address the question of whether this is likely to also occur in the wild. We conclude that it is highly likely that wild predators select prey or selectively feed on body parts according to their macronutrient composition, a possibility that could have significant implications for ecological and foraging theory, as well as applied wildlife conservation and management.

Our analysis draws upon recent work on the problem of time in quantum gravity and causally symmet- ric local hidden variable theories. Our conclusion weighs the strengths and weaknesses of the approach (...) and points towards paths for future development. (shrink)

We provide an analysis of the empirical consequences of the AdS/CFT duality with reference to the application of the duality in a fundamental theory, effective theory and instrumental context. Analysis of the first two contexts is intended to serve as a guide to the potential empirical and ontological status of gauge/gravity dualities as descriptions of actual physics at the Planck scale. The third context is directly connected to the use of AdS/CFT to describe real quark-gluon plasmas. In the latter context, (...) we find that neither of the two duals are confirmed by the empirical data. (shrink)

A crisis continues to brew within the pharmaceutical research and development (R&D) enterprise: productivity continues declining as costs rise, despite ongoing, often dramatic scientific and technical advances. To reverse this trend, we offer various suggestions for both the expansion and broader adoption of modeling and simulation (M&S) methods. We suggest strategies and scenarios intended to enable new M&S use cases that directly engage R&D knowledge generation and build actionable mechanistic insight, thereby opening the door to enhanced productivity. What M&S requirements (...) must be satisfied to access and open the door, and begin reversing the productivity decline? Can current methods and tools fulfill the requirements, or are new methods necessary? We draw on the relevant, recent literature to provide and explore answers. In so doing, we identify essential, key roles for agent-based and other methods. We assemble a list of requirements necessary for M&S to meet the diverse needs distilled from a collection of research, review, and opinion articles. We argue that to realize its full potential, M&S should be actualized within a larger information technology framework—a dynamic knowledge repository—wherein models of various types execute, evolve, and increase in accuracy over time. We offer some details of the issues that must be addressed for such a repository to accrue the capabilities needed to reverse the productivity decline. (shrink)

One of the issues with introducing animal rights law is whether the problem is quantitative or qualitative, whether it can be achieved by working within existing legal paradigms or whether it requires a new set of paradigms. The answer is fundamental: a quantitative problem can be solved by applying more of the same solutions, while a qualitative problem requires completely different solutions. The qualitative camp can be represented by, say, Professor Gary Francione, demanding not only rights for animals but that (...) they have personhood and are no longer considered “property.” The quantitative approach can be finely represented by Professor David Favre, who has argued for many years that we can make progress by developing existing legal principles to give some rights to some animals, and he does so eloquently in his new book. He is clear in his view that progress is, and can continue to be, made with a series of steps, as he puts it, “climbing the slippery slope toward personhood” (p. viii).His case is supported by looking backward—progress made in establishing the rules governing humans in their relationships with animals—as well as forward to developments that will support continuing improvement in the lives of animals, not least the potential for technology (for example, through cell- and plant-based meat). At the same time, he also rightly rejects the concepts of animal welfare and animal rights being at odds, let alone either of them being a panacea for better lives for animals.One aspect of animal law that Favre believes does need to change is that of property status. As he says, the status of animals as personal property is “critical to the future of animal law” (p. 25). In general, the solutions have been largely binary—that animals simply cannot be property for them to have meaningful rights or that animals can be property and still have rights. The former makes intuitive good sense (and is consistent with the objectives of the human abolitionist movements) but would have enormous effects on economic activity throughout the world. The latter is appealing because it does not change the current paradigm, so can be developed more easily.Favre's premise is that we are moving toward rights for animals, so we need to find a way of integrating animals into the current legal system rather than having to destroy and reconstruct the legal system. His ingenious solution is to propose a fourth category of property, alongside real, personal, and intellectual property: “living property.”Within this category, he envisages using the common law concept of the trust to provide equitable “self-ownership,” where an animal has equitable “ownership” while a human retains legal “ownership.” He then connects this concept to adaptations in other aspects of law that start to recognize the selfhood of animals, creating a platform onto which broader and deeper rights for animals can develop, such as the status of “animalhood” (p. 72) and the corresponding legal right of consideration before decisions are made by the state affecting an animal's fundamental interests (such as continuing to be alive). By putting animals in a separate class—rather than uncomfortably leaving them in personal property—he creates a possible route for animal rights that seems less paradigm-busting than removing them from being property altogether.Drawing on evidence from criminal law, tort law, equity (trusts), property law, and family law, he shows how in many places—with a focus on states in the United States—existing laws are being adapted (“green shoots” p. 81) to recognize that animals are more than personal property, in ways that cannot be explained simply through the growth of regulations. For example, family law is starting to recognize that in the division of matrimonial assets, companion animals cannot be treated simply like any other personal property such as a table or a car based on who paid for them. Because animals are “living property,” the courts should take account of other aspects, such as who cared for the animals and who looked after them. Similarly, the concept of extending trust law so that an animal can be the beneficiary of a trust—in the same way as a human can be but inanimate personal property cannot—shows that the law can understand that companion animals can play a large emotional role in our lives (as well as we in theirs), such that we want to ensure proper care for them after we die.The book raises important issues. First, it is intentionally about domestic animals, with their close links with humans, so the potential for laws to engage is much easier than with, say, farmed animals. The danger with solutions that focus on domestic or charismatic animals (e.g., dogs, chimpanzees, elephants) is that the arguments may be pertinent essentially only to those species and therefore hard to apply to animals of less charismatic species, say in a factory farm (but who are present in much greater numbers and generally badly treated in comparison). He “leaves for another day” (p. 32) the discussion about other animals. Hopefully that day will come, as it would be interesting to see how Favre could extend his concept to animals for whom the public has less affection and less appreciation of their capacities (and for whom the prospect of death is much more real and imminent).Secondly, public support for these ideas about living property may simply not be present. If there is not a sufficient groundswell of support for changing the status of animals, then whether one proposes changing it to not-property or “self-owned” property doesn't matter (if someone doesn't like needles, it doesn't matter whether the needle you propose to use is big or small). This may be too pessimistic, of course (people can be helped to overcome a fear of needles, and one way to start is with small needles). Perhaps the law should start with small changes to recognize at least a few animals—their sentience, their capacities for pleasure and pain, their emotions and preferences, their potential for autonomy—and build public support from there.There is also the underlying and more radical point about whether these ideas—the trust for a beloved companion set up by the human, the divorce settlement that doesn't just give the companion to the party who paid for them—are actually bringing about changes for animals as such or are simply adapting laws to help humans, recognizing human needs, and do not actually change the status of animals. The ends are still humans, and the means are still animals.This is not intended to paint a bleak picture: The more bluntand uncompromising part of the animal rights movement that has been focused on the qualitative problem has hardly been successful at getting animal rights laws passed anywhere in the world, so everything that moves us closer to a better, richer, more thoughtful view of animals will help. Favre's approach has ingenuity, shows good sense, and has the potential to bring about real animal rights. The themes and cases in this book that show how courts and legislatures are becoming more aware of the sentience of at least some animals, as well as proposing a middle path in the debate about animals as property, are important in the journey toward recognition of animal rights. Even more important, they may actually work. (shrink)

Perceived size is a function of viewing distance, retinal images size, and various contextual cues such as linear perspective and the size and location of neighboring objects. Recently, we demonstrated that illusion magnitudes of classic visual size illusions may be greatly enhanced or reduced by adding dynamic elements. Specifically, a dynamic version of the Ebbinghaus illusion (classically considered a “size contrast” illusion) led to a greatly enhanced illusory effect, whereas a dynamic version of the Corridor illusion (a “size constancy” illusion) (...) led to a greatly diminished illusory effect. Although these differences may arise from the different processes underlying these illusions (size contrast vs. size constancy), the dynamic variants we tested in our previous work also differed in the nature of the dynamic elements; specifically, whereas the Dynamic Ebbinghaus included a moving target and inducers that changed size and position, the Dynamic Corridor only included a moving target on a static background. Here, we explore further dynamic versions of the Ebbinghaus illusion and the Corridor and Ponzo illusions by separately manipulating three types of dynamic elements: target motion, context translation, and dynamic changes in context. Across five experiments examining 21 dynamic illusory configurations, adding target motion or a dynamically changing context separately resulted in little-to-no illusory effect. In contrast, the combination of target motion and a dynamically changing context led to a robust size illusion, consistent with an interactive effect. However, illusory effects that exceeded the matched classic, static illusory configuration were only observed for the dynamic versions of the Ebbinghaus illusion and the Revealed Ponzo illusions, in which the contextual elements changed size. We conclude that the combination of target motion and a dynamically changing context are necessary to produce dynamic size illusions, but that enhancement above and beyond static illusions may be largely specific to size contrast effects. Our results have important implications for the integration of motion signals, a ubiquitous environmental stimulus, in the perception of object size. (shrink)

Given an ideal $I$ , let $\mathbb{P}_{I}$ denote the forcing with $I$ -positive sets. We consider models of forcing axioms $MA(\Gamma)$ which also have a normal ideal $I$ with completeness $\omega_{2}$ such that $\mathbb{P}_{I}\in \Gamma$ . Using a bit more than a superhuge cardinal, we produce a model of PFA (proper forcing axiom) which has many ideals on $\omega_{2}$ whose associated forcings are proper; a similar phenomenon is also observed in the standard model of $MA^{+\omega_{1}}(\sigma\mbox{-closed})$ obtained from a supercompact cardinal. (...) Our model of PFA also exhibits weaker versions of ideal properties, which were shown by Foreman and Magidor to be inconsistent with PFA. Along the way, we also show (1) the diagonal reflection principle for internally club sets ( $\mathit{DRP}(IC_{\omega_{1}})$ ) introduced by the author in earlier work is equivalent to a natural weakening of “there is an ideal $I$ such that $\mathbb{P}_{I}$ is proper”; and (2) for many natural classes $\Gamma$ of posets, $MA^{+\omega_{1}}(\Gamma)$ is equivalent to an apparently stronger version which we call $MA^{+\operatorname{Diag}}(\Gamma)$.

At the very heart of the causal theory of perception are the peculiar examples sometimes called veridical hallucinations. These examples originate with Grice, who used them to prove ‘conclusively’ that when we say, for example, ‘Jane saw John’, we mean that John is the cause of certain visual experiences or impressions had by Jane.

Two epistemic principles are Knowledge Exclusion and Belief Exclusion. Knowledge Exclusion says that it is necessarily the case that if an agent knows that p, then she does not believe that ∼p, and Belief Exclusion says that it is necessarily the case that if an agent believes that q, then she does not believe that ∼q. Many epistemologists find it reasonable to reject the latter principle and accept the former. I argue that this is in fact not reasonable by proposing (...) a case in which an agent can use that she has contradictory beliefs towards a proposition as decisive evidence for that proposition. A natural response is that this case conflicts with common assumptions about the relation between knowledge, contradictory beliefs and rationality. I reply by drawing ideas from Lasonen-Aarnio’s remarks on unreasonable knowledge to explain why these common assumptions do not threaten my argument. (shrink)

Philosophical writing on gratitude displays a pronounced preference for targeted gratitude (A’s being grateful to B for x) over propositional gratitude (A’s being grateful that p), treating the latter as a poor, less interesting cousin of the former, when it treats it at all.

It argues that propositional gratitude is not only not reducible to targeted gratitude but indeed is more basic than it and that (...) propositional gratitude is morally important because of its conceptual connections to the virtue of humility.
