Parkinson's disease patients receiving dopaminergic treatment may experience bursts of creativity. Although this phenomenon is sometimes recognized among patients and their clinicians, the association between dopamine replacement therapy in PD patients and creativity remains underexplored. It is unclear, for instance, whether DRT affects creativity through convergent or divergent thinking, idea generation, or a general lack of inhibition. It is also unclear whether DRT only augments pre-existing creative attributes or generates creativity de novo. Here, we tested a group of PD patients (...) when “on” and “off” dopaminergic treatment on a series of tests of creative problem-solving, and related their performance to a group of matched healthy controls as well as to their pre-PD creative skills and measures of inhibition/impulsivity. Results did not provide strong evidence that DRT improved creative thinking in PD patients. Rather, PD patients “on” medication showed less flexibility in divergent thinking, generated fewer ideas via insight, and showed worse performance in convergent thinking overall than healthy controls. Pre-PD creative skills predicted enhanced flexibility and fluency in divergent thinking when PD patients were “on” medication. However, results on convergent thinking were mixed. Finally, PD patients who exhibited deficits in a measure of inhibitory control showed weaker convergent thinking while “on” medication, supporting previous evidence on the importance of inhibitory control in creative problem-solving. Altogether, results do not support the hypothesis that DRT promotes creative thinking in PD. We speculate that bursts of artistic production in PD are perhaps conflated with creativity due to lay conceptions of creativity. (shrink)

Objective: to develop and test the factorial structure of a new self-determination theory-based measure of behavioral regulation in children. Method: 590 (F = 51.7%) children aged 7-11 years completed the Motivation to Exercise and Diet (MED-C) questionnaire, which comprises 16 items (8 for exercise and 8 for diet) grouped into eight-factors (5 motivations and 3 needs). Psychometric testing included confirmatory factor analysis and internal consistency. Measurement invariance analyses were also performed to evaluate whether the factorial structure of the MED-C was (...) equivalent for gender (male vs. female), age ( 10yo) and the perception of having at least one parent with overweight or obesity (yes vs. no). Results: factorial analysis confirmed an acceptable factors solution for the MED-C and a good fit to the data for both the exercise and the diet subscales assessed independently. The Maximal Reliability coefficient revealed good reliability for the exercise and the diet subscales. Moreover, the MED-C factor structure was invariant across group comparisons. Discussion: findings support the construct validity and reliability of the MED-C. Therefore, it represents the first validated instrument simultaneously measuring motivational regulation and psychological need satisfaction in the context of children’s exercise and diet. Considering the goodness of these results, scale percentile ranks of the total score distribution as well as the z-score and the T-score were provided for clinical and research purposes. Conclusion: The MED-C might support the understanding of motivations and needs of children with weight problems and assist their process of behavioural change in primary and secondary prevention programs. Psychological factors represent, in fact, potential targets for interventions to increase children’s motivation to exercise and diet. (shrink)

This essay gives an account of epistemic deference for agents with imprecise credences. I look at the two main imprecise deference principles in the literature, known as Identity Reflection and Pointwise Reflection (Moss, 2021). I show that Pointwise Reflection is strictly weaker than Identity Reflection, and argue that, if you are certain you will update by conditionalisation, you should defer to your future self according to Identity Reflection. Then I give a more general justification for Pointwise and Identity Reflection from (...) the assumption that you defer to someone whenever you consider their doxastic state to be better than yours, in the sense of leading to better decision-making.

Thought experiments are fictional narratives that widen our cognitive horizons both in the sciences and in philosophy. In the present paper we argue that they can perform this function by bringing one’s perspective into view. Despite being traditionally conceived as devices that transmit true propositions to their readers, thought experiments are also particularly apt to express a specific theoretical perspective through the use of imagination. We suggest that this is a significant epistemic feature that is often overlooked in the debate. (...) After presenting our analysis of thought experiments (Section 2) and of the role that imagination plays in them (Section 3), we revisit Galileo Galilei’s use of imaginary cases in light of our account (Section 4). We show that the main aims of Galileo’s thought experiments are to highlight how different perspectives endorsed by fictional characters affect imagination and to invite readers to actively engage in perspectives that are different from their own. This results in a clash of perspectives which plays a crucial epistemic role (Section 5). Readers of thought experiments do not passively absorb information, but critically assess the other’s perspective. In the final part of the paper, we individuate different ways in which readers can react to thought experiments. (shrink)

In the last few years, several philosophers have highlighted the social dimension of imagination. In this paper I argue that thought experiments prompt social uses of imaginings if we understand them as props in games of make-believe. In prescribing to imagine stories that develop through fictional narratives, authors of thought experiments prompt their readers to engage in the same imaginative project—at least in its salient aspects—and to endorse their conclusions. Contributions on this topic focus on cases where coordination across imaginers (...) is immediately successful. However, this is not the end of the story. I draw attention to situations where this is not the case, as the practice of thought experimentation often proceeds through criticism, rejections, and amendments. I focus on cases where imaginers do not endorse the conclusion proposed by the author of a thought experiment and either (i) fully reject the principles of generation, (ii) draw different fictional truths from the same principles, or (iii) amend the principles. Although cases of imaginative disharmony are usually dismissed as failures, I acknowledge them as fruitful steps in the cognitive advancement achievable by thought experiments. Cooperative imaginers challenge the rules of the game in meaningful ways, which leads to enhancing fictional scenarios and framing them through different perspectives. (shrink)

This paper generalises an argument for probabilism due to Lindley [9]. I extend the argument to a number of non-classical logical settings whose truth-values, seen here as ideal aims for belief, are in the set $\{0,1\}$, and where logical consequence $\models $ is given the “no-drop” characterization. First I will show that, in each of these settings, an agent’s credence can only avoid accuracy-domination if its canonical transform is a (possibly non-classical) probability function. In other words, if an agent values (...) accuracy as the fundamental epistemic virtue, it is a necessary requirement for rationality that her credence have some probabilistic structure. Then I show that for a certain class of reasonable measures of inaccuracy, having such a probabilistic structure is sufficient to avoid accuracy-domination in these non-classical settings. (shrink)

The current debate on literary cognitivism in the philosophy of fiction typically assumes that we can rigorously distinguish between fictional and factual, and focuses on the question of whether and how works of fiction can impart propositional knowledge to the reader. In this paper we suggest that this way of framing the debate may be problematic. We argue that works of fiction almost inevitably include a reference to the real world and that – contrary to what is usually assumed – (...) the exchange between fiction and reality is vivid as well as potentially fruitful. We shed a new light on these complex dynamics by building on the metaphors of trade exchange and smuggling between the two worlds. While the current debate exclusively focuses on cognitively relevant goods that “officially” cross the border through “customs”, as it were, we show that exchanges between fiction and reality run deeper. Indeed, as we show, a substantial part of the cognitive impact that we derive from fiction goes “under the table” and is “smuggled” from fiction to reality. As such, it bypasses the audience’s conscious control, which in turn explains the manipulative force that fiction can exert. Smuggling takes place when cognitively relevant contents are passed on to the reader in subliminal ways, as it happens when they imprint implicit biases or prejudices, shift perspectives or subtly modify habits or patterns of behavior. By elaborating on the metaphors of trade exchange and smuggling, we aim at presenting a more comprehensive and nuanced understanding of the relations between fiction and reality and on the impact that imagination has on our real-world beliefs.

In Practicing Safe Sects F. LeRon Shults provides scientific and philosophical resources for having “the talk” about religious reproduction: where do gods come from – and what are the costs of bearing them in our culturally pluralistic, ecologically fragile environment?

Accuracy-first epistemologists argue that rational agents have probabilistically coherent credences. But why should we care, given that we can’t help being incoherent? A common answer: probabilistic coherence is an ideal to be approximated as best one can. De Bona (in: Philos Sci 84(2), 189–213, 2017) and Staffel (in: Unsettled thoughts: a theory of degrees of rationality, Oxford University Press, 2019) show how accuracy-firsters can spell out this answer by adopting an appropriate notion of approximate coherence. In this essay, I argue (...) that De Bona and Staffel’s proposal is not entirely satisfactory, because it does not show whether, or why, it’s generally better to be more rather than less approximately coherent from an accuracy-first perspective. To address this point, I give a characterisation of their notion of approximate coherence in terms of accuracy. This shows that accuracy-firsters should maintain that more approximately coherent credences are better than less approximately coherent ones _if and only if_ they accept that it’s better to miss out on less rather than more guaranteed accuracy.

The regulation of narcotic medications used in narcotic addiction treatment is unique in medical therapeutics. Physicians who want to use narcotics for this indication must obtain a separate annual registration from the Drug Enforcement Administration. Annual registration is contingent on compliance with both the DEA's security regulations as well as treatment regulations jointly promulgated by the Food and Drug Administration and the National Institute on Drug Abuse.During the last decade, a number of events have occurred that persuaded NIDA that it (...) is time to reevaluate the current method by which the Department of Health and Human Services regulates methadone treatment. As a result of research during the past twenty years, we have learned about the effective components of methadone treatment. In comparison to other available treatment modalities for opioid addiction, methadone treatment is uniquely effective when administered by well-trained medical staffs. (shrink)

The question of the morality of abortion has long been the subject of intense, sometimes acrimonious debate. Even people within the same religious or philosophical tradition often disagree on the issue. For example, there are Christians who are “pro- choice” and there are Christians who are “pro-life.” Both sides marshal biblical, theological, and philosophical arguments in support of their positions. The substance of the abortion debate seems to reduce to one tricky question: when does personhood begin? Christian experts in various (...) fields, such as theology, biblical studies, ethics, and philosophy, have protracted disagreements over this question. In this article we will apply insights from the current literature on epistemic peer disagreement to the abortion issue. We will assume that there is only one correct answer to the abortion question. However, after making a crucial distinction between rationality as understood by internalists versus externalists, we will argue that there is more than one rational answer to the abortion question, since there is more than one rational way to weight evidence. We will conclude that, in a case of disagreement between two Christians who are epistemic peers with regards to the morality of abortion, both parties can be rational in adhering to their respective positions, but that this does not entail or even support ethical relativism.

According to a recent philosophical claim, “works of fiction are thought experiments” (Elgin 2007: 47), though there are relevant differences, as the role of spoilers shows—they can ruin a novel but improve the understanding we can gain through a thought experiment. In the present article I will analyze the role of spoilers and argue for a more differentiated perspective on the relation between literature and thought experiments. I will start with a short discussion of different perspectives on thought experiments and (...) argue that the mental-model view and the conception of games of make-believe are most promising for developing the present analogy. Then I will assess the similarities and differences between thought experiments and other works of fiction. I will focus on the role of spoilers and, more generally, on the foretaste context, of which they are part. This context guides readers of literary works of art to draw their attention to the literary and aesthetic quality of the text. In the case of thought experiments, on the other hand, it (i) prompts them to accept the presence of fictional elements in worldly-cognitive works and (ii) draws their attention towards cognitively relevant elements of the story. A discussion of Borges’ Pierre Menard in the last part will show that literary works of art become thought experiments if they are embedded in an appropriate foretaste context. Spoilers, thus, unveil that even works which—due to their length or plenty of detail—usually are not considered thought experiments, can perform similar cognitive functions. (shrink)

Ethics for Enemies comprises three original philosophical essays on torture, terrorism, and war. F. M. Kamm deploys ethical theory in her challenging new treatments of these most controversial practical issues. First she considers the nature of torture and the various occasions on which it could occur, in order to determine why it might be wrong to torture a wrongdoer held captive, even if this were necessary to save his victims. In the second essay she considers what makes terrorism wrong--whether it (...) is the intention to harm civilians, rather than harm to them being 'collateral damage,' or something else--and whether terrorism is always wrong. The third essay discusses whether having a right reason, in the sense of a right intention, is necessary in order for a war to be just. Kamm then examines ways in which the harms of war can be proportional to the achievement of the just cause and other goods that war can bring about, so as to make the declaration of war permissible.

RESUMO Neste artigo, analiso um conjunto de seis cartões comerciais pertencentes a uma duradoura campanha de marketing da Liebig Extract of Meat Co. A análise crítica dos textos promocionais produzidos na virada do século XX oferece insights significativos sobre os mecanismos discursivos que contribuíram para a hegemonização do capitalismo burguês. Diferentemente de outras formas de publicidade, os cartões comerciais não são rapidamente descartados e esquecidos; pelo contrário, eles podem se distanciar dos produtos anunciados para se tornar parte dos discursos populares (...) de instrução em massa. Como produtos e produtores de ideologias capitalistas, os anúncios são um local privilegiado de inscrição do capitalismo e, portanto, se prestam a uma análise crítica. Minha análise mostra como os textos selecionados se baseiam e texturizam os discursos do progresso, impregnados como crenças colonialistas e desencadeando uma cadeia de ações pela qual, mesmo antes de realmente obterem os cartões, são promulgadas ações e crenças capitalistas. ABSTRACT In this paper, I analyze a set of six trading cards belonging to Liebig’s Extract of Meat Co. long-standing marketing campaign. The critical analysis of promotional texts produced at the turn of the 20th century offer meaningful insights on the discursive mechanisms that contributed to the hegemonization of bourgeois capitalism. Unlike other forms of advertising, trading cards are not rapidly discarded and forgotten; on the contrary, they can detach themselves from the advertised products to become part of popular discourses of mass instruction. As both products and producers of capitalist ideologies, ads are a privileged site of inscription of capitalism, and thus lend themselves to a critical analysis. My analysis shows how the selected texts draws on and textures the discourses of progress, inculcated as colonialist beliefs and triggering an actional chain whereby, even before they actually obtained the cards, capitalist actions and beliefs are enacted.

Con questa ricerca vorremmo soffermarci su quattro punti che riteniamo fondamentali per la comprensione dell'influenza delle fonti neoplatoniche nella Firenze del Quattrocento. Il punto di partenza è l'analisi dei rapporti tra i due massimi esponenti del neoplatonismo fiorentino: Pico della Mirandola e Marsilio Ficino, autori fondamentali non solo per le loro interpretazioni, ma anche per aver riscoperto e tradotto, dopo secoli di silenzio, i tesori del pensiero greco. Non si comprenderebbe l'influenza delle fonti neoplatoniche antiche nel Quattrocento senza rendere conto (...) del confronto – spesso molto aspro – tra i due protagonisti pricipali della riscoperta rinascimentale di Platone e di tutta la tradizione neoplatonica. Il secondo punto affronta un'importante interpretazione in senso tomista dell'opera di Pico, quella di Giovanni di Napoli, che aiuta ad intendere tanto le differenze tra il mirandolano e Ficino, quanto ad introdurre all'influenza importantissima dello Pseudo-Dionigi in tutto il dibattito filosofico del tardo Quattrocento. Il terzo punto cerca di affrontare un tema fondamentale: l'esigenza di definire e organizzare nuovi ordini del sapere. Dal recupero del passato emergevano nuove contraddizioni e nuove esigenze, non si trattava affatto di una semplice imitazione dell'antico, ma al contrario, significava farlo rivivere in nuove forme e costruire nuovi sistemi dei saperi capaci di rispondere alle esigenze culturali e politiche che stavano alla base della nascita del moderno. L'ultimo punto riguarda invece un'analisi specifica tra il pensiero di Giovanni Pico e lo Pseudo-Dionigi, discorso che ovviamente comporta anche l'analisi di altre fonti fondamentali, in particolare Damascio. Parole chiave: Neoplatonismo fiorentino, Giovanni Pico, della Mirandola, Marsilio Ficino, Pseudo-Areopagita. (shrink)

This commentary reinterprets our recent data on the cerebellar contribution to different cognitive functions in light of Braitenberg and coworkers's hypothesis about the sequence-in/sequence-out cerebellar mode of operation in the motor domain. Cerebellar involvement in spatial data processing, procedural learning, verbal fluency, application of grammatical rules, and writing is dependent on sequence processing.

As tentativas de invasões germânicas iniciadas no século II a.C. culminaram com a tomada de Roma em 476. Os novos chefes adotaram o latim como língua oficial, e grande parte dos textos latino-germânicos foi reunida e publicada por G.H.Pertz (MGH).

A new English translation of Schelling’s unfinished magnum opus, complete with a contextualizing introduction by the translator.

Based on the novel data collected through original fieldwork on five syntactic phenomena (the position of the finite verb in embedded clauses, in sentences with a modal verb, negative concord, position of focused light/heavy objects in main clauses with a complex tense, scrambling) in the heritage language Mòcheno, we show that i) there exist two populations – one exhibiting intra-speaker variation between German and Italian word orders, and one lacking it; ii) these two populations are the result of diatopic variation (...) and, to a lesser extent, of diastratic variation. The results reached through quantitative statistical analysis are partially convergent with those arrived at by traditional theoretical syntax on Mòcheno, but our analysis has allowed us to shed new light on a series of so-far neglected or poorly understood phenomena. More specifically, we discovered that there exists micro-variation fed by diastratic (age) variation within the Roveda variety, which represents the only case in Mòcheno in which age is a relevant factor in determining variation. We also showed that the traditional claim that the Palù variety is “more German” than the other Mòcheno variety is surely to be confirmed, but we could refine it by showing that German word orders are also accepted by speakers of other varieties and that the acceptability of these word orders in competition with the Italian syntax is not fed by the age of speakers (no diastratic variation). Finally, we showed that the acceptance of German word orders across speakers varies according to the phenomenon investigated: negation is the phenomenon in which German word orders are more likely to be accepted, whereas embedded clauses are the phenomenon in which German word orders are more likely to be rejected.

First published in 1818, The World as Will and Representation contains Schopenhauer's entire philosophy, ranging through epistemology, metaphysics, philosophy of mind and action, aesthetics and philosophy of art, to ethics, the meaning of life and the philosophy of religion, in an attempt to account for the world in all its significant aspects. It gives a unique and influential account of what is and is not of value in existence, the striving and pain of the human condition and the possibility of (...) deliverance from it. This new translation of the first volume of what later became a two-volume work reflects the eloquence and power of Schopenhauer's prose and renders philosophical terms accurately and consistently. It offers an introduction, glossary of names and bibliography, and succinct editorial notes, including notes on the revisions of the text which Schopenhauer made in 1844 and 1859. (shrink)
