Thought Experiments

Much recent work on philosophical methodology has focused on whether we should accept evidence: the claim that philosophers use intuitive judgments about cases as evidence for/against philosophical theories. This paper outlines a new way of thinking about the philosophical method of appealing to cases such that evidence is true but not as it is typically understood. The idea proposed is that, when philosophers appeal to cases, they are engaged in a project of conceptual engineering and that, within that project, intuitions (...) about cases provide evidence as to the normative constraints which are relevant within that project. The paper demonstrates that this is a feasible interpretation of the way that cases are appealed to in recent journal issues, and makes the case that this would be a better way to think of what philosophers are doing when they appeal to cases.

…A reconstructed imaginal account of Alexander’s (the Great) historical letter to Aristotle pursuant to his (in-) famous meeting with the gymnosophist Dandimus on the paradoxes of Zeno ( presaging those of Nagarjuna ) as a means of presenting a synthesis of the stasis and dynamism implicit in the potential of a phenomenally real world beyond a rigid designation of a chain-of-being taxonomy where animal dignity resides side by side with predator-prey relations and a mind-laden ( theory ) of evolution.

Prior research found correlations between reflection test performance and philosophical tendencies among laypeople. In two large studies (total N = 1299)—one pre-registered—many of these correlations were replicated in a sample that included both laypeople and philosophers. For example, reflection test performance predicted preferring atheism over theism and instrumental harm over harm avoidance on the trolley problem. However, most reflection-philosophy correlations were undetected when controlling for other factors such as numeracy, preferences for open-minded thinking, personality, philosophical training, age, and gender. Nonetheless, (...) some correlations between reflection and philosophical views survived this multivariate analysis and were only partially confounded with either education or self-reported reasoning preferences. Unreflective thinking still predicted believing in God whereas reflective thinking still predicted believing that (a) proper names like ‘Santa’ do not necessarily refer to entities that actually exist and (b) science does reveal the fundamental nature of the world. So some robust relationships between reflection and philosophical tendencies were detected even among philosophers, and yet there was clearly more to the link between reflection and philosophy. To this end, demographic and metaphilosophical hypotheses are considered. (shrink)

Thought experiments figure prominently in contemporary epistemology. Beyond that humdrum observation, controversy abounds. The aim of this paper is to make progress on two fronts. On the descriptive front, the aim is to illuminate what the practice of using thought experiments involves. On the normative front, the aim is to illuminate what the practice of using thought experiments should involve. Thought experiments result in judgments that are passed on to further philosophical reasoning. What are these judgments? What is the point (...) of making them? What basis do we have for making them? A conception of thought experiments includes answers to these three questions. My thesis is that epistemologists should use thought experiments in accordance with a conception of them organized around the idea of explanation. My case for endorsing the thesis rests on the fruitfulness of the interventions in current debates about the content, point, and basis of thought experiment judgments that it suggests. (shrink)

The Challenge from Cognitive Diversity (CCD) states that demography-specific intuitions are unsuited to play evidential roles in philosophy. The CCD attracted much attention in recent years, in great part due to the launch of an international research effort to test for demographic variation in philosophical intuitions. In the wake of these international studies, the CCD may prove revolutionary. For, if these studies uncover demographic differences in intuitions, then, in line with the CCD, there would be good reason to challenge philosophical (...) views that rely on those intuitions for evidential support. I argue that philosophical views that rely on demography-specific intuitions for evidential support need not be threatened by such findings. I first provide a detailed analysis of the epistemological principles driving the CCD and distinguish three formulations of this challenge. I then show that there are good reasons to reject all such formulations of the CCD. (shrink)

Those who wish to defend the role of aesthetic values in science face a dilemma: Either aesthetic language is used metaphorically for what are ultimately epistemic features, or aesthetic language is used literally but it is difficult to see the importance of such values in science. I introduce a new account that gets around this problem by looking to an overlooked source of aesthetic value in science: the relation between form and content. I argue that a fit between the content (...) of a thought experiment, and the way in which that content is formulated, can have important epistemic pay offs through contributing to scientific understanding.

Experimental ethicists investigate traditional ethical questions with non-traditional means, namely with the methods of the empirical sciences. Studies in this area have made heavy use of philosophical thought experiments such as the well-known trolley cases. Yet, the specific function of these thought experiments within experimental ethics has received little consideration. In this paper we attempt to fill this gap. We begin by describing the function of ethical thought experiments, and show that these thought experiments should not only be classified according (...) to their function but also according to their scope. On this basis we highlight several ways in which the use of thought experiments in experimental ethics can be philosophically relevant. We conclude by arguing that experimental philosophy currently only focuses on a small subcategory of ethical thought experiments and suggest a broadening of its research agenda. (shrink)

Using Riemann’s Rearrangement Theorem, Øystein Linnebo (2020) argues that, if it were possible to apply an infinite positive weight and an infinite negative weight to a working scale, the resulting net weight could end up being any real number, depending on the procedure by which these weights are applied. Appealing to the First Postulate of Archimedes’ treatise on balance, I argue instead that the scale would always read 0 kg. Along the way, we stop to consider an infinitely jittery flea, (...) an infinitely protracted border conflict, and an infinitely electric glass rod. (shrink)

Otto Neurath’s empiricist methodology of economics and his contributions to politi- cal economy have gained increasing attention in recent years. We connect this research with contemporary debates regarding the epistemological status of thought experiments by reconstructing Neurath’s utopias as linchpins of thought experiments. In our three reconstructed examples of different uses of utopias/dystopias in thought experiments we employ a reformulation of Häggqvist’s model for thought experiments and we argue that: (1) Our reformulation of Häggqvist’s model more adequately complies with many (...) uses of thought experiments, especially with the open-ended discussions of utopias and dys- topias in thought experiments. (2) As a strict logical empiricist, Neurath is committed to a strictly empiricist account of thought experiments. John Norton’s empiricist argument view can indeed account for the justifications of empirical beliefs and genuine discoveries targeted by scientific utopianism in three distinct (yet connected) ways, all of which Neur- ath already contemplated: (2.I) Dealing with utopias and thought experiments on a regular basis increases creativity and inventiveness. (2.II) Particular ways of presenting knowl- edge facilitate scientific discovery and social progress. (2.III) The use of utopias in thought experiments can prompt conceptual change and allow access to new phenomena. We con- clude by highlighting that, even though thought experiments support a positive attitude for exploring new social possibilities, Neurath points out that active decisions are unavoidable. The exploration of alternatives and the awareness of a need for decisions in policy discus- sion avert a technocratic outlook in social science. (shrink)

El artículo aborda la relación entre Nietzsche y Levinas, en particular se enfrenta a la concepción de cuerpo y narración sostenida por cada autor. En ese sentido se afirma que la aparente distancia que existe entre ambos pensadores puede reducirse a partir de las temáticas que se estudian en este trabajo. A la luz de todo ello, la lectura del cuerpo de Nietzsche y la comprensión de narración de Levinas no habrían sido solo reflexiones filosóficas, sino más bien el pretexto (...) para que ambos pensadores critiquen el pensamiento establecido y propongan, cada uno a su modo, un quehacer filosófico que afecta directamente la existencia humana en cuanto reflexión sobre las formas como se comprende la vida misma.

Philosophers have debated at length the epistemological status of scientific thought experiments. I contend that the literature on this topic still lacks a common conceptual framework, a lacuna that produces radical disagreement among the participants in this debate. To remedy this problem, I suggest focusing on the distinction between the internal and the external validity of an experiment, which is also crucial for thought experiments. I then develop an account of both kinds of validity in the context of thought experiments. (...) I show that we can naturally conceptualise internal validity in terms of games of make-believe. Then, I argue that external validity is best defined as accurate representation of a target system. Finally, I turn back to the current debate on thought experiments and show that my diarchic account provides a general framework that can be shared by the competing philosophical views, as well as a fruitful guide for their reconciliation.

ABSTRACT According to edenic idealism, our ordinary object terms refer to items in the manifest world—the world of primitive objects and properties presented in experience. I motivate edenic idealism as a response to scenarios where it is difficult to match the objects in experience with corresponding items in the external world. I argue that edenic idealism has important semantic advantages over realism: it is the most intuitive view of what we are actually talking about when we use terms for objects.

Philosophers are often credited with particularly well-developed conceptual skills. The ‘expertise objection’ to experimental philosophy builds on this assumption to challenge inferences from findings about laypeople to conclusions about philosophers. We draw on psycholinguistics to develop and assess this objection. We examine whether philosophers are less or differently susceptible than laypersons to cognitive biases that affect how people understand verbal case descriptions and judge the cases described. We examine two possible sources of difference: Philosophers could be better at deploying concepts, (...) and this could make them less susceptible to comprehension biases (‘linguistic expertise objection’). Alternatively, exposure to different patterns of linguistic usage could render philosophers vulnerable to a fundamental comprehension bias, the linguistic salience bias, at different points (‘linguistic usage objection’). Together, these objections mount a novel ‘master argument’ against experimental philosophy. To develop and empirically assess this argument, we employ corpus analysis and distributional semantic analysis and elicit plausibility ratings from academic philosophers and psychology undergraduates. Our findings suggest philosophers are better at deploying concepts than laypeople but are susceptible to the linguistic salience bias to a similar extent and at similar points. We identify methodological consequences for experimental philosophy and for philosophical thought experiments. (shrink)

At the height of the Covid-19 pandemic, frontline medical professionals at intensive care units around the world faced gruesome decisions about how to ration life-saving medical resources. These events provided a unique lens through which to understand how the public reasons about real-world dilemmas involving trade-offs between human lives. In three studies (total N = 2298), we examined people’s moral attitudes toward the triage of acute coronavirus patients, and found elevated support for utilitarian triage policies. These utilitarian tendencies did not (...) stem from period change in moral attitudes relative to pre-pandemic levels–but rather, from the heightened realism of triage dilemmas. Participants favoured utilitarian resolutions of critical care dilemmas when compared to structurally analogous, non-medical dilemmas–and such support was rooted in prosocial dispositions, including empathy and impartial beneficence. Finally, despite abundant evidence of political polarisation surrounding Covid-19, moral views about critical care triage differed modestly, if at all, between liberals and conservatives. Taken together, our findings highlight people’s robust support for utilitarian measures in the face of a global public health threat, and illustrate how the dominant methods in moral psychology (e.g. trolley cases) may deliver insights that do not generalise to real-world moral dilemmas.

Good physical experiments conform to the basic methodological standards of experimental design: they are objective, reliable, and valid. But is this also true of thought experiments? Especially problems of personal identity have engendered hypothetical scenarios that are very distant from the actual world. These imagined situations have been conspicuously ineffective at resolving conflicting intuitions and deciding between the different accounts of personal identity. Using prominent examples from the literature, I argue that this is due to many of these thought experiments (...) not adhering to the methodological standards that guide experimental design in nearly all other disciplines. I also show how empirically unwarranted background assumptions about human physiology render some of the hypothetical scenarios that are employed in the debate about personal identity highly misleading.

Predmet ove disertacije se u najširem smislu može posmatrati kao odgovor na meta-epistemološko pitanje o zadatku epistemologije i načinu na koji bi epistemološki projekat trebalo voditi. U radu prikazujemo i kritički analiziramo debatu savremenih metafilozofa o ulozi, a posledično i prirodi intuicija u savremenoj analitičkoj filozofiji. Osnovni cilj našeg rada je da odbranimo stav da epistemičke intuicije igraju ulogu evidencije u okviru metoda analize pojma znanja. Ovaj stav deo je standardne slike o epistemološkoj metodologiji koja se poslednjih godina dovodi u (...) pitanje, kako od strane naučno orijentisanih filozofskih naturalista, tako i filozofskih tradicionalista. Kao ključni problem izdvajamo neuspeh zastupnika standardne slike o filozofskoj metodologiji da ponude odgovor na pitanje prirode intuicija. Prema našem mišljenju ovaj neuspeh posledica je propusta koji prave kako zastupnici, tako i kritičari pozivanja na intuicije u filozofiji kada pristupaju ovoj metafilozofskoj debati. Jednom kada uvidimo da moramo podrobnije razumeti metode u okviru kojih se pozivamo na intuicije, uočićemo da filozofske intuicije ne smemo posmatrati kao homogenu klasu, već da ispitivanju njihove prirode moramo pristupiti u okviru pojedinačnih filozofskih disciplina. Kada smo ovu strategiju primenili u našem istraživanju došli smo do zaključka da intuicije kao izraz pojmovne kompetencije igraju ulogu evidencije u metodima pojmovne analize i misaonog eksperimenta koji su karakteristični za savremenu analitičku epistemologiju.

In this paper, I argue that appeals to intuition in Analytic Philosophy are not compelling arguments because intuitions are not the sort of thing that has the power to rationally persuade other professional analytic philosophers. This conclusion follows from reasonable premises about the goal of Analytic Philosophy, which is rational persuasion by means of arguments, and the requirement that evidence for and/or against philosophical theses used by professional analytic philosophers be public (or transparent) in order to have the power to (...) rationally persuade other professional analytic philosophers. Since intuitions are not public (or transparent) evidence, it follows that appeals to intuition are not compelling arguments for and/or against philosophical theses because they lack the power to rationally persuade other professional analytic philosophers.

In this essay, I argue that Wittgenstein attempted to clarify ethics through a procedure that, by analogy with “transcendental arguments”, I call “transcendental thought experiment”. Specifically, after offering a brief perspectival account of both transcendental arguments and transcendental thought experiments, I focus on a thought experiment proposed by Wittgenstein in his 1929 'Lecture on Ethics', arguing that it deserves the title of “transcendental”.

Sometimes, scientific models are either intended to or plausibly interpreted as representing nonactual but possible targets. Call this “hypothetical modeling”. This paper raises two epistemological challenges concerning hypothetical modeling. To begin with, I observe that given common philosophical assumptions about the scope of objective possibility, hypothetical models are fallible with respect to what is objectively possible. There is thus a need to distinguish between accurate and inaccurate hypothetical modeling. The first epistemological challenge is that no account of the epistemology of (...) hypothetical models seems to cohere with the most characteristic function of scientific modeling in general, i.e., surrogative representation. The second epistemological challenge is a version of “reliability challenges” familiar from other areas. There is a challenge to explain how hypothetical models could be a reliable guide to what is possible, given that they are not and cannot be compared against their nonactual targets and updated accordingly. I close with some brief remarks on possible solutions to these challenges. (shrink)

In some domains experts perform better than novices, and in other domains experts do not generally perform better than novices. According to empirical studies of expert performance, this is because the former but not the latter domains make available to training practitioners a direct form of learning feedback. Several philosophers resource this empirical literature to cast doubt on the quality of philosophical expertise. They claim that philosophy is like the dubious domains in that it does not make available the good, (...) direct kind of learning feedback, and thus there are empirical grounds for doubting the epistemic quality of philosophical expertise. I examine the empirical studies that are purportedly bad news for professional philosophers. On the basis of that examination, I provide three reasons why the empirical study of non-philosophical expertise does not undermine the status of philosophical expertise. First, the non-philosophical task-types from which the critics generalize are unrepresentative of relevant philosophical task-types. Second, empirical critiques of non-philosophical experts are often made relative to the performance of linear models—a comparison that is inapt in a philosophical context. Third, the critics fail to discuss findings from the empirical study of non-philosophical expertise that have more favorable implications for the epistemic status of philosophical expertise. In addition to discussing implications for philosophical expertise, this article makes progress in the philosophical analysis of the science of expertise and expert development. (shrink)

Though sometimes maligned, “trolleyology” offers an effective means of opening and framing, not only classes in ethics, but indeed any introductory philosophy course taking a broadly “puzzle-based” approach. When properly sequenced, a subset of the thought experiments that are trolleyology’s stock-in-trade can generate a series of puzzles illustrating the shortcomings of our untutored moral intuitions, and which thus motivate the very enterprise of moral theorizing. Students can be engaged in the attempt to resolve said puzzles, inasmuch as they’re accessible and (...) compelling, and their resolutions generally easy to achieve. Once thus engaged, students can be directed to the fact that they had already rolled up their sleeves and begun “doing philosophy.” In this way, engagement with trolleyological puzzles can serve as a “microcosm” for philosophy more broadly, illustrating the processes of critical thinking that are likewise the stock-in-trade of philosophers across many different domains of inquiry.

African perspectives on personhood and personal identity and their relation to those of the West have become far more central in mainstream Western discussion than they once were. Not only are African traditional views with their emphasis on the importance of community and social relations more widely discussed, but that emphasis has also received much wider acceptance and gained more influence among Western philosophers. Despite this convergence, there is at least one striking way in which the discussions remain apart and (...) that is on a point of method. The Western discussion makes widespread use of thought experiments. In the African discussion, they are almost entirely absent. In this article, we put forward a possible explanation for the method of thought experiment being avoided that is based on considerations stemming from John Mbiti’s account of the traditional African view of time. These considerations find an echo in criticism offered of the method in the Western debate. We consider whether a response to both trains of thought can be found that can further bring the Western and African philosophical traditions into fruitful dialogue. (shrink)

In philosophical thought experiments, as in ordinary discourse, our understanding of verbal case descriptions is enriched by automatic comprehension inferences. Such inferences have us routinely infer what else is also true of the cases described. We consider how such routine inferences from polysemous words can generate zombie intuitions: intuitions that are ‘killed’ (defeated) by contextual information but kept cognitively alive by the psycholinguistic phenomenon of linguistic salience bias. Extending ‘evidentiary’ experimental philosophy, this paper examines whether the ‘zombie argument’ against materialism (...) is built on zombie intuitions. We examine the hypothesis that contextually defeated stereotypical inferences from the noun ‘zombie’ influence intuitions about ‘philosophical zombies’. We document framing effects (‘zombie’ vs ‘duplicate’) predicted by the hypothesis. Findings undermine intuitions about the conceivability of ‘philosophical zombies’ and address the philosophical ‘hard problem of consciousness’. Findings support a deflationary response: The impression that principled obstacles prevent scientific explanation of how physical processes give rise to conscious experience is generated by philosophical arguments that rely on epistemically deficient intuitions.

This chapter sheds light on a response to experimental philosophy that has not yet received enough attention: the reflection defense. According to proponents of this defense, judgments about philosophical cases are relevant only when they are the product of careful, nuanced, and conceptually rigorous reflection. The chapter argues that the reflection defense is misguided: Five studies (N>1800) are presented, showing that people make the same judgments when they are primed to engage in careful reflection as they do in the conditions (...) standardly used by experimental philosophers.

The last two decades have seen the proliferation of the empirical study of philosophy. This dissertation defends the practice and argues that to understand the way contingent features of the practice of philosophy affect the epistemic standing of philosophers, we need to draw upon a wider and more varied set of empirical data than is sometimes supposed. To explore this, the dissertation focuses on two places where the practices of the discipline of philosophy have an effect on the epistemology of (...) philosophy. -/- First, the dissertation discusses the interaction between notable works of philosophy and their readers. In particular, it critiques the method of defending the epistemic standing of philosophers through careful examination of notable works of philosophy to discern the methods in the text. Ultimately this method is epistemically unmotivated. It is instead far more important to study how people have interacted and reacted to works of philosophy. -/- Second, the dissertation defends the use of lexicography in philosophy. Using "intuition" as a case study, the dissertation argues metasemantically and lexicographically that philosophers often use common words with meanings unique to philosophy. -/- Through both discussions it is argued that experimental philosophers and epistemologists of philosophy need to drastically expand the sorts of data they collect and consider in their theorizing. -/- ​.

Recent literature has seen a surging interest in the modal principle involved in the Gettier-style thought experiments. According to the necessitation thesis, the modal principle underlying the Gettier-style thought experiments takes the form of a principle of necessitation. It is widely agreed that the necessitation thesis is seriously threatened by the problem of deviant realizations. Based on the Gricean pragmatic theory of communication, I defend the necessitation thesis against the problem of deviant realizations. The present account bears some significant similarities (...) to Pierre Saint-Germier’s account. After comparing and contrasting these two accounts, I argue that the differences between them actually speak in favor of the present account over Saint-Germier’s one. (shrink)

Experimental philosophy has focused attention on the role that intuitive responses to philosophical cases play in philosophical argumentation. The method of appealing to such cases has been dubbed the “method of cases,” and, in recent work, Edouard Machery has both defended its prevalence and uniformity in philosophical practice, and criticized its epistemic value. In this paper, I argue that there is no single method of cases, but rather a set of methods of cases. To defend this claim, I distinguish and (...) articulate these different methods and argue that they better explain several paradigmatic appeals to cases. This result not only challenges the homogeneity of the method of cases; it also stocks our methodological toolbox with additional interpretive tools which help us to not only better understand philosophical arguments, but to better understand the significance of experimental work.

Thought experiments, one of the most effective ways of acquiring knowledge, are an intellectual tool frequently used by scientists or thinkers in their fields of study. Thought experiments used to respond to scientific issues are considered scientific thought experiments, while thought experiments used for philosophical problems are called philosophical thought experiments. In this context, firstly, the differences between scientific and philosophical thought experiments are determined in the article. In particular, philosophical thought experiments are often needed in discussions within the field (...) of epistemology. For this reason, in the rest of the study, the knowledge argument put forward against the idea of physicalism, which is one of the important views in epistemology and which claims that the natural world is basically physical and that everything can be explained by physical laws is included. The knowledge argument briefly argues that there are non-physical properties and information that can only be discovered through conscious experience. Accordingly, it is argued that someone who has all physical knowledge about another conscious may lack knowledge of what it would feel like to have subjective experiences of that entity such as qualia. Consequently, the main idea of the article is to reveal how an epistemological thesis has been questioned by various philosophers in the context of philosophical thought experiments such as Mary’s room, ‘What is it like to be a Bat’, The Martian and the Philosophical Zombie. - Bilgi edinmenin en etkili yollarından bir tanesi olarak değerlendirilen düşünce deneyleri bilim insanları ya da düşünürler tarafından kendi çalışma alanları içerisinde sıklıkla başvurulan düşünsel bir araçtır. Bilimsel konulara cevap vermek amacıyla gerçekleştirilen düşünce deneyleri bilimsel düşünce deneyleri olarak değerlendirilirken, felsefi sorunlara yönelik kullanılan düşünce deneyleri ise felsefi düşünce deneyleri olarak adlandırılmaktadır. Bu kapsamda makalede ilk olarak bilimsel ve felsefi düşünce deneyleri arasındaki farklılıklar belirlenmektedir. Özellikle, epistemoloji alanı içerisinde yer alan tartışmalarda felsefi düşünce deneylerine sıklıkla ihtiyaç duyulmaktadır. Bu nedenle çalışmanın devamında epistemolojide önemli görüşlerden bir tanesi olan ve doğal dünyanın en temelde fiziksel olduğu ve fiziksel yasalarla her şeyin açıklanabileceği iddiasında bulunan fizikalizm düşüncesine karşı ileri sürülmüş bilgi argümanına yer verilmektedir. Bilgi argümanı kısaca sadece bilinçli deneyim yoluyla elde edilebilen ve fiziksel olarak ifade edilemeyen öznel deneyimlerin ve özelliklerin olduğunu savunmaktadır. Buna göre, başka bir bilinçli varlık hakkında bütün fiziksel bilgiye sahip olan birinin, o varlığın qualia gibi öznel deneyimlerine sahip olmasının nasıl bir his olduğu konusundaki bilgilerden yoksun olabileceği fikri savunulmaktadır. Bu doğrultuda, makalenin temel savı fizikalizm gibi epistemolojik bir teze Mary’nin Odası, ‘Yarasa Olmak Nasıl Bir Şeydir’, Marslı ve Felsefi Zombi gibi felsefi düşünce deneyleri bağlamında çeşitli filozoflarca nasıl itiraz edildiğini ve düşünce deneylerinin bu bağlamda nasıl kullanıldığını ortaya koymaktır.

Recent experimental studies indicate that epistemically irrelevant factors can skew our intuitions, and that some degree of scepticism about appealing to intuition in philosophy is warranted. In response, some have claimed that philosophers are experts in such a way as to vindicate their reliance on intuitions—this has become known as the ‘expertise defence’. This paper explores the viability of the expertise defence, and suggests that it can be partially vindicated. Arguing that extant discussion is problematically imprecise, we will finesse the (...) notion of ‘philosophical expertise’ in order to better reflect the complex reality of the different practices involved in philosophical inquiry. On this basis, we offer a new version of the expertise defence that allows for distinct types of philosophical expertise. The upshot of our approach is that wholesale vindications or rejections of the expertise defence are shown to be unwarranted; we must instead turn to local, piecemeal investigations of philosophical expertise. Lastly, in the spirit of taking our own advice, we exemplify how recent developments from experimental philosophy lend themselves to this approach, and can empirically support one instance of a successful expertise defence.

Many philosophical thought experiments and arguments involve unusual cases. We present empirical reasons to doubt the reliability of intuitive judgments and conclusions about such cases. Inferences and intuitions prompted by verbal case descriptions are influenced by routine comprehension processes which invoke stereotypes. We build on psycholinguistic findings to determine conditions under which the stereotype associated with the most salient sense of a word predictably supports inappropriate inferences from descriptions of unusual (stereotype-divergent) cases. We conduct an experiment that combines plausibility ratings (...) with pupillometry to document this “salience bias.” We find that under certain conditions, competent speakers automatically make stereotypical inferences they know to be inappropriate.

We examine a prominent naturalistic line on the method of cases, exemplified by Timothy Williamson and Edouard Machery: MoC is given a fallibilist and non-exceptionalist treatment, accommodating moderate modal skepticism. But Gettier cases are in dispute: Williamson takes them to induce substantive philosophical knowledge; Machery claims that the ambitious use of MoC should be abandoned entirely. We defend an intermediate position. We offer an internal critique of Macherian pessimism about Gettier cases. Most crucially, we argue that Gettier cases needn’t exhibit (...) ‘disturbing characteristics’ that Machery posits to explain why philosophical cases induce dubious judgments. It follows, we show, that Machery’s central argument for the effective abandonment of MoC is undermined. Nevertheless, we engineer a restricted variant of the argument—in harmony with Williamsonian ideology–that survives our critique, potentially limiting philosophy’s scope for establishing especially ambitious modal theses, despite traditional MoC’s utility being partially preserved.

Effective Altruism (EA) is both a philosophy and a movement. The main criticism on EA is that by donating to charities EA leaves fundamental moral issues such as global poverty and injustice intact. EA arguably does not promote radical institutional change which could lead to an ultimate eradication of the problems that may endanger people’s lives in the first place. In this article this critique is reinforced from a different point of view. The criticism on EA has been mainly on (...) the performative or the empirical aspect of the movement. That is, criticism on EA focuses on evaluating the practical realisation of its mandates with little, if any, evaluation on its philosophical foundation. My aim in this paper is to extend the critique but from a different angle, that is, by going back to its philosophical underpinnings. By exploring the philosophical foundation of EA, I would like to show how EA is not authentic altruism as it is founded on the sacrifice of the Other whom is supposed to be saved. (shrink)

Is there a role for aesthetic judgements in science? One aspect of scientific practice, the use of thought experiments, has a clear aesthetic dimension. Thought experiments are creatively produced artefacts that are designed to engage the imagination. Comparisons have been made between scientific (and philosophical) thought experiments and other aesthetically appreciated objects. In particular, thought experiments are said to share qualities with literary fiction as they invite us to imagine a fictional scenario and often have a narrative form (Elgin 2014). (...) But philosophical discussions of aesthetics in science have focused mainly on the epistemic role of beauty and elegance when it comes to theories and mathematical proofs, and thought experiments have been widely overlooked. My aim in this chapter is to address how the aesthetic choices scientists make in the design of a thought experiment contribute to its function: to communicate, convince, or explain a theory or phenomenon. A key issue is whether any aesthetic features in science provide anything beyond catching our attention, or are at best, a mere heuristic aid. I respond to accounts that argue this way and show how formulation is important in scientific thought experiments and, similarly to literary fictions, there is more than one way of interpreting a thought experiment scenario. I end by considering which literary examples are most appropriate when making comparisons with thought experiments. As a result, the difference between representations in art and science raised in current discussions is not as stark as it has been made out to be, and science is a more heterogeneous practice than has been allowed. Part of the value of thought experiments in scientific practice includes the qualities they share with literary works. (shrink)

This article aims to analyze the functioning of thought experiments in ethics. We will demonstrate that although many thought experiments in ethics can be reconstructed as arguments, according to the thesis defended by John Norton, its reconstructed version does not have the same epistemic force. We will argue that the reconstructed versions are not capable of bringing the same type of understanding in relation to thought experiments, which have an explanatory advantage that arguments do not have. Therefore, arguments are not (...) a sufficient condition for solving problems within ethics and also within thought experiments in this area. We will argue that emotions can be one of the non-argumentative factors that can produce negative and positive interference on thought experimenters and thought experiment, which cannot be demonstrated accurately in the reconstructed version. In this way, the reconstructed version is not able to convey an adequate understanding of emotions and other influences. Finally, we will elaborate on two thought experiments that demonstrate the need to use emotions in moral actions based on the criticism produced by Flávio Williges against traditional moral theories. These thought experiments can be reconstructed as arguments, but without giving us the same understanding that thought experiments are capable of. (shrink)

Um dos principais problemas epistemológicos que podem ser encontrados no estudo dos experimentos mentais diz respeito ao critério de escolha entre casos que produzam resultados contraditórios. Que justificação possuímos para escolher entre C e ~C? James Roberto Brown argumenta a favor de um critério de probabilidade, onde se atribui probabilidade aos dois fenômenos e o mais provável de ser verdadeiro é o que aceitamos. John Norton argumenta que experimentos mentais são argumentos, por isso eles podem ser reconstruídos como argumentos. Através (...) desse processo podemos encontrar as falhas na argumentação do experimento e decidir, através de justificação lógica, qual é a conclusão correta. A abordagem de Brown se mostra muito infrutífera por não apresentar como o cálculo de probabilidade deve funcionar, nem como é possível atribuir probabilidades a verdade dos resultados dos experimentos mentais. Por outro lado, para aceitar a resposta de Norton, necessitamos aceitar que experimentos mentais realmente façam uso de argumentos e que isso seja tudo o que podemos dizer sobre eles. Essa estruturação não permite nenhuma outra fonte epistêmica para justificar os resultados dos experimentos metais. (shrink)

Suppositional reasoning can seem spooky. Suppositional reasoners allegedly (e.g.) “extract knowledge from the sheer workings of their own minds” (Rosa), even where the knowledge is synthetic a posteriori. Can literary fiction pull such a rabbit out of its hat? Where P is a work’s fictional ‘premise’, some hold that some works reason declaratively (supposing P, Q), imperatively (supposing P, do Q), or interrogatively (supposing P, Q?), and that this can be a source of knowledge if the reasoning is good. True, (...) I will argue, although only within the context of judicious critical interpretation. Further evident constraints include that the form of the suppositional reasoning needs to be declarative or imperative, and that the fictional ‘premise’ of the work needs to be a metaphysical counterfactual possibility, not merely a temporal counterfactual and not merely an epistemic possibility or probabilistic supposition.

According to hedonistic act utilitarianism, an act is morally right if and only if, and because, it produces at least as much pleasure minus pain as any alternative act available to the agent. This dissertation gives a partial defense of utilitarianism against two types of objections: action guidance objections and intuitive objections. In Chapter 1, the main themes of the dissertation are introduced. The chapter also examines questions of how to understand utilitarianism, including (a) how to best formulate the moral (...) explanatory claim of the theory, (b) how to best interpret the phrase "pleasure minus pain," and (c) how the theory is related to act consequentialism. The first part (Chapters 2 and 3) deals with action guidance objections to utilitarianism. Chapter 2 defines two kinds of action guidance: doxastic and evidential guidance. It is argued that utilitarianism is evidentially but not doxastically guiding for us. Chapter 3 evaluates various action guidance objections to utilitarianism. These are the objections that utilitarianism, because it is not doxastically guiding, is a bad moral theory, fails to be a moral theory, is an uninteresting and unimportant moral theory, and is a false moral theory. The second part (Chapters 4, 5 and 6) deals with intuitive objections to utilitarianism. Chapter 4 presents three intuitive objections: Experience Machine, Transplant, and Utility Monster. Three defenses of utilitarianism are subsequently evaluated. Chapter 5 and 6 introduces two alternative defenses of utilitarianism against intuitive objections, both of which concern the role that imagination plays in thought experimentation. In Chapter 5, it is argued that we sometimes unknowingly carry out the wrong thought experiment when we direct intuitive objections against utilitarianism. In many such cases, we elicit moral intuitions that we believe give us reason to reject utilitarianism, but that in fact do not. In Chapter 6, it is argued that using the right kind of sensory imagination when we perform thought experiments will positively affect the epistemic trustworthiness of our moral intuitions. Moreover, it is suggested that doing so renders utilitarianism more plausible. In Chapter 7, the contents of the dissertation are summarized. (shrink)

In her short story “Stable Strategies for Middle Management,” Eileen Gunn imagines a future in which Margaret, an office worker, seeks radical genetic enhancements intended to help her secure the middle-management job she wants. One source of the story’s tension and dark humor is dramatic irony: readers can see that the enhancements Margaret buys stand little chance of making her life go better for her; enhancing is, for Margaret, probably a prudential mistake. This paper argues that our positions in the (...) real world are sufficiently similar to Margaret’s position in Gunn’s fictional world that we should take this story seriously as grounding an argument from analogy for the conclusion that radical genetic enhancements are, for us, probably a prudential mistake. The paper then defends this method. When the question at hand is one of speculative ethics, there is no method better fit to the purpose than argument from analogy to speculative fiction. (shrink)

John D. Norton is responsible for a number of influential views in contemporary philosophy of science. This paper will discuss two of them. The material theory of induction claims that inductive arguments are ultimately justified by their material features, not their formal features. Thus, while a deductive argument can be valid irrespective of the content of the propositions that make up the argument, an inductive argument about, say, apples, will be justified (or not) depending on facts about apples. The argument (...) view of thought experiments claims that thought experiments are arguments, and that they function epistemically however arguments do. These two views have generated a great deal of discussion, although there hasn’t been much written about their combination. I argue that despite some interesting harmonies, there is a serious tension between them. I consider several options for easing this tension, before suggesting a set of changes to the argument view that I take to be consistent with Norton’s fundamental philosophical commitments, and which retain what seems intuitively correct about the argument view. These changes require that we move away from a unitary epistemology of thought experiments and towards a more pluralist position. (shrink)

Entende-se que os experimentos mentais são dispositivos da imaginação que podem nos fornecer crenças que constituem conhecimento. John D. Norton apresentou uma abordagem que se tornou influente para explicar como os experimentos mentais científicos podem produzir novos conhecimentos so- bre o mundo. Ele afirma que não há nada distintivo nos experimentos men- tais, uma vez que sustenta que eles funcionam exatamente como argumen- tos. Neste artigo, contestamos sua abordagem. Examinamos aspectos essen- ciais de sua abordagem, que envolvem as noções de (...) “argumento” e “inferên- cia” para mostrar que um sujeito que chega a saber algo através da execução ou condução de um experimento mental dificilmente será considerado como tendo efetivamente executado um argumento ou um processo de raciocínio inferencial.

In this study, the existing definitions of thought experiments and the origin of this concept with its first usage in history will be discussed. Then, the epistemology of Ernst Mach, who conducted the first systematic research on thought experiments, will be provided in order to grasp his views on this subject correctly. In this context, the views of James Brown and John Norton, who support different positions, will be briefly described in order to draw the general framework of the epistemological (...) status of thought experiments. Finally, it will be revealed that the biological theory of knowledge and the doctrine of the economy of thought are the sources of Mach’s ‘instinctive knowledge’ argument about scientific thought experiments.

The question of where the knowledge comes from when we conduct thought experiments has been one of the most fundamental issues discussed in the epistemological position of thought experiments. In this regard, Pierre Duhem shows a skeptical attitude on the subject by stating that thought experiments cannot be evaluated as real experiments or cannot be accepted as an alternative to real experiments. James R. Brown, on the other hand, states that thought experiments, which are not based on new experimental evidence (...) or logically derived from old data, called the Platonic thought experiment, provide intuitive access to a priori knowledge. Unlike Brown, John D. Norton strictly criticizes the idea that thought experiments provide mysterious access to the knowledge of the physical world, and states that thought experiments cannot provide knowledge that transcends empiricism. In the context of the NortonBrown debate, in this article, Brown's stance on thought experiments is supported by critically analyzing the thoughts put forward on the subject. -/- Düşünce deneylerini gerçekleştirdiğimizde sonucunda elde edilen bilginin nereden geldiği sorusu düşünce deneylerinin epistemolojik konumuna ilişkin tartışılan en temel konulardan bir tanesidir. Bu doğrultuda, Pierre Duhem düşünce deneylerinin gerçek deneyler ile aynı statüde değerlendirilemeyeceğini ve hatta düşünce deneylerinin gerçek deneylerin bir alternatifi olarak bile kabul edilemeyeceğini belirterek konuya ilişkin şüpheci bir tavır sergilemektedir. James R. Brown ise yeni deneysel kanıtlara dayanmayan ya da eski verilerden mantıksal olarak türetilmeyen, Platoncu düşünce deneyi olarak adlandırılan düşünce deneylerinin a priori bilgiye sezgisel erişim sağladığını ifade etmektedir. Brown’ın aksine, John D. Norton düşünce deneylerinin fiziksel dünyanın bilgisine gizemli bir erişim sağladığı yönündeki düşünceyi kesin bir dille eleştirmekte ve düşünce deneylerinin ampirizmi aşan bir bilgi sağlamasının mümkün olamayacağını ifade etmektedir. Norton-Brown tartışması çerçevesinde bu makalede, Brown'un düşünce deneylerine ilişkin tutumu, konuyla ilgili düşüncelerin eleştirel olarak analiz edilmesiyle desteklenmektedir. (shrink)

The principle of Identity of Indiscernibles has been challenged with various thought experiments involving symmetric universes. In this paper, I describe a fractal universe and argue that, while it is not a symmetric universe in the classical sense, under the assumption of a relational theory of space it nonetheless contains a set of objects indiscernible by pure properties alone. I then argue that the argument against the principle from this new thought experiment resists better than those from classical symmetric universes (...) three main objections put forth against this kind of arguments.

Psycholinguistic methods hold great promise for experimental philosophy. Many philosophical thought experiments and arguments proceed from verbal descriptions of possible cases. Many relevant intuitions and conclusions are driven by spontaneous inferences about what else must also be true in the cases described. Such inferences are continually made in language comprehension and production. This chapter explains how methods from psycholinguistics can be employed to study such routine automatic inferences, with a view to assessing intuitions and reconstructing arguments. We demonstrate how plausibility (...) ratings, pupillometry, and reading time measurements can be used to examine hypotheses about automatic inferences in speech and text comprehension. Two experiments on inferences from polysemous (perception-)verbs provide evidence of a potentially consequential ‘salience bias’. Findings help assess intuitions about unusual cases and analyse a philosophical paradox (‘argument from hallucination’). The paper thus illustrates how we can adapt psycholinguistic methods for philosophical purposes and demonstrates the methods’ philosophical usefulness. (shrink)

Works of science fiction tend to describe hypothetical futures, or counterfactual pasts or presents, to entertain their readers. Philosophical thought experiments tend to describe counterfactual situations to test their readers’ philosophical intuitions. Indeed, works of science fiction can sometimes be read as containing thought experiments. I compare one especially famous thought experiment from Plato’s Republic with what I read as two thought experiments from Isaac Asimov’s Foundation Trilogy. All three thought experiments concern myths used in political contexts, and comparing them (...) permits me to analyze the morality of political mythologizing. (shrink)

This article considers the novel approach for epistemological interpretation of biomimetics or bionics and biosimilarity in different abiogenetic works with the terminological correction for elimination of the reifications (concretisms, hypostatizations), simplified metaphors and the results of metonymy. In the last part of this article one can see the analysis of the mistakes and problems of complex abiogenetic or supramolecular evolution projects within the aspects of the Conway law and the social organization of science and publishing sphere in subjective postmodern capitalistic (...) conditions.

In economics, thought experiments are frequently justified by the difficulty of conducting controlled experiments. They serve several functions, such as establishing causal facts, isolating tendencies, and allowing inferences from models to reality. In this paper, I argue that thought experiments served a further function in economics: facilitating the quantitative definition and measurement of the theoretical concept of utility, thereby bridging the gap between theory and statistical data. I support my argument by a case study, the “hypothetical experiments” of the Norwegian (...) economist Ragnar Frisch (1895-1973). Frisch aimed to eliminate introspection and a subjective concept of utility from economic reasoning. At the same time, he sought behavioral foundations for economic theory that enabled quantitative reasoning. By using thought experiments to justify his set of choice axioms and facilitating the operationalization of utility, Frisch circumvented the problem of observing utility via actual experiments without eliminating the concept of utility from economic theory altogether. As such, these experiments helped Frisch to empirically support the theory’s most important results, such as the laws of demand and supply, without the input of new empirical findings. I suggest that Frisch’s experiments fulfill the main characteristics of thought experiments. (shrink)

The “film as philosophy” (FAP) hypothesis turned into a field if its own right during the 2000s, after S. Mulhall’s On Film (2001). In this work, Mulhall defended that some films philosophize for themselves. This caused controversy. Around the same time of On Film’s release, B. Russell published the article “The philosophical limits of film” (2000). This article had one of the first attacks against FAP, posing some main objections based on metaphilosophical grounds, which were called the “generality” and the (...) “explicitness” objections. These objections made by Russell and by M. Smith are based on the idea that film and philosophy are too different in their purposes or ways of presentation, ideas that are grounded in implicit or explicit conceptions of philosophy. In this chapter, these will be analyzed, as well as some other metaphilosophically grounded objections, as a line of reasoning connecting to attempts of responding to them will be drawn. After doing so, it will be concluded that their metaphilosophical grounds are implausible, and, thus, they are not definite objections against FAP. (shrink)
