This paper questions the adequacy of the explicit cancellability test for conversational implicature as it is commonly understood. The standard way of understanding this test relies on two assumptions: first, that that one can test whether a certain content is conversationally implicated, by checking whether that content is cancellable, and second, that a cancellation is successful only if it results in a felicitous utterance. While I accept the first of these assumptions, I reject the second one. I (...) argue that a cancellation can succeed even if it results in an infelicitous utterance, and that unless we take this possibility into account we run the risk of misdiagnosing philosophically significant cases.

Cancellability is an essential feature of implicatures. However, its reliability has been challenged by several cases and examples in which conversational implicatures seem to be hard or even impossible to cancel. Should it then be concluded that not all implicatures are cancellable, and therefore Grice's cancellability test should be weakened or abandoned? The present paper addresses this problem by drawing a distinction between theoretical and practical cancellability, where the latter concept captures the (un)reasonableness of explicit or contextual cancellation. By (...) analyzing three legal cases of misleading advertising, I show how the indefensibility of an interpretation can account for the practical uncancellability of an implicature. To explain and account for the reasonableness of an interpretation, the presumptive inferences involved must be reconstructed and evaluated considering different dimensions, such as the conversational context and the associated presumptions.

Keith DeRose and Stewart Cohen object to the fallibilist strand of pragmatic invariantism regarding knowledge ascriptions that it is committed to non-cancelable pragmatic implications. I show that this objection points us to an asymmetry about which aspects of the conveyed content of knowledge ascriptions can be canceled: we can cancel those aspects that ascribe a lesser epistemic standing to the subject but not those that ascribe a better or perfect epistemic standing. This situation supports the infallibilist strand of pragmatic invariantism (...) according to which knowledge semantically requires absolute certainty but this claim is often pragmatically weakened: it turns out that exactly those aspects of the conveyed content are cancelable that this view claims are pragmatic. I also argue that attributor contextualism and relativism do not have an alternative explanation of this phenomenon. (shrink)

A large body of research has found that people judge bad foreseen side effects to be more intentional than good ones. While the standard interpretation of this Side-Effect Effect takes it to show that the ordinary concept of intentionality is influenced by normative considerations, a competing account holds that it is the result of pragmatic pressure to express moral censure and, thus, that the SEE is an experimental artifact. Attempts to confirm this account have previously been unsuccessful, but Lindauer and (...) Southwood :181–186, 2021) present a study that appears to provide support for it, by cancelling the SEE. We are not convinced. Here, we detail three studies testing their interpretation. The results indicate that it is the purported cancellation, rather than the SEE, that is an experimental artifact.

Those who want to deny the ‘ought implies can’ principle often turn to weakened views to explain ‘ought implies can’ phenomena. The two most common versions of such views are that ‘ought’ presupposes ‘can’, and that ‘ought’ conversationally implicates ‘can’. This paper will reject both views, and in doing so, present a case against any pragmatic view of ‘ought implies can’. Unlike much of the literature, I won't rely on counterexamples, but instead will argue that each of these views fails (...) on its own terms. ‘Ought’ and ‘can’ do not obey the negation test for presupposition, and they do not obey the calculability or the cancelability tests for conversational implicature. I diagnose these failures as partly a result of the importance of the contrapositive of ‘ought implies can’. I end with a final argument emphasizing the role the principle plays in moral thinking, and the fact that no pragmatic account can do it justice. (shrink)

Despite its enormous popularity, Russell’s theory of definite descriptions has received various criticisms. Two of the most important objections against this theory are those arising from the Argument from Incompleteness and the Argument from Donnellan’s Distinction. According to the former although a speaker may say something true by assertively uttering a sentence containing an incomplete description , on the Russellian analysis such a sentence expresses a false proposition; so, Russell’s theory cannot adequately deal with such sentences. According to the latter (...) objection a descriptive sentence is actually ambiguous—it expresses a general proposition when the description contained in it is used attributively, and a singular proposition when the description in question is used referentially; Russell’s theory is inadequate as it fails to capture this ambiguity and offers an analysis according to which a descriptive sentence expresses only a general proposition. These objections are examined in the present dissertation. It is shown here that these objections arise from: (i) ignoring the distinction between the meaning of a sentence and the assertions made by using it, (ii) the failure to distinguish between the semantic meaning of a sentence and the pragmatic meaning with which it is used on a particular occasion. To make the distinction mentioned in (i), a significant part of Scott Soames’ theory concerning meaning and assertions has been adopted in this dissertation; and, to make the distinction mentioned in (ii), a test, namely the cancellability test, and two Distinguishing Criteria, namely DC-1 and DC-2, have been developed here. It has been argued here that if we properly make the relevant distinctions, then we will find that: (a) the phenomenon cited by the Argument from Incompleteness can be well explained keeping the Russellian analysis of descriptive sentences intact, (b) the phenomenon arising from the Argument from Donnellan’s Distinction raises an issue of pragmatics and is irrelevant to Russell’s semantic analysis of descriptive sentences. So, none of the above criticisms poses a genuine threat to Russell’s theory of definite descriptions; his theory actually provides, to a large extent, a correct semantic analysis of descriptive sentences.

Is it tautological to call an action "wrongful discrimination?" Some philosophers and political theorists answer this question in the affirmative and claim that the term "discrimination" is intrinsically evaluative. Others agree that "discrimination" usually conveys the action’s moral wrongness but claim that the term can be used in a purely descriptive way. In this paper, we present two corpus studies and two experiments designed to test whether the folk concept of discrimination is evaluative. We demonstrate that the term has (...) undergone a historical development and is nowadays no longer used purely descriptively. Further, we show that this evaluation cannot be cancelled without yielding a contradiction. We conclude that the descriptive use of "discriminatory" is a thing of the past. (shrink)

It is widely held that there are important differences between indicative conditionals (e.g. “If the authors are linguists, they have written a linguistics paper”) and subjunctive conditionals (e.g. “If the authors had been linguists, they would have written a linguistics paper”). A central difference is that indicatives and subjunctives convey different stances towards the truth of their antecedents. Indicatives (often) convey neutrality: for example, about whether the authors in question are linguists. Subjunctives (often) convey the falsity of the antecedent: for (...) example, that the authors in question are not linguists. This paper tests prominent accounts of how these different stances are conveyed: whether by presupposition or conversational implicature. Experiment 1 tests the presupposition account by investigating whether the stances project – remain constant – when embedded under operators like negations, possibility modals, and interrogatives, a key characteristic of presuppositions. Experiment 2 tests the conversational-implicature account by investigating whether the stances can be cancelled without producing a contradiction, a key characteristic of implicatures. The results provide evidence that both stances – neutrality about the antecedent in indicatives and the falsity of the antecedent in subjunctives – are conveyed by conversational implicatures.

In psychophysical experiments, the use of a psychophysical procedure of brightness/darkness cancellation shed light on interactions between spatial arrangement and figure–ground contrast in the perceptual filling in of achromatic and colored surfaces.Achromatic and chromatic Kanizsa squares with varying contrast, contrast polarity, and inducer spacingwere used to test how these factors interact in the perceptual filling in of surface brightness or darkness. The results suggest that the neuronal processing of surfaces with apparent contrast, leading to figure–ground segregation (i.e., perceptual organization), (...) is governed by mechanisms that integrate both luminance contrast and spatial information carried by the inducing stimuli, while discarding information on contrast polarity or color. The findings are discussed in relation to earlier observations on brightness assimilation and contrast. They support theories of nonantagonistic neural mechanisms suppressing local contrast or color signs in brightnessbased figure–ground percepts. Such mechanismsmight be necessary to cancel potentially conflicting polarities in geometricallycomplex visual stimuli so that perceptual filling in resulting in the most plausible representation of figure and ground can be achieved.

one hand, it raises fundamental doubts about the Davidsonian project, which seems to involve isolating specifically semantic knowledge from any other knowledge or skill in a way reflected by the ideal of homophony. Indexicality forces a departure from this ideal, and so from the aspiration of deriving the truth conditions of an arbitrary utterance on the basis simply of axioms which could hope to represent purely semantic knowledge. In defence of Davidson, I argue that once his original idea for dealing (...) with the familiar indexical expressions is suitably implemented, in terms of theorems expressing conditional truth-conditions, the contrast between semantic and nonsemantic knowledge occurs in an appropriate place: between knowledge of the conditional truth conditions themselves (semantic), and knowledge of their antecedents (non-semantic). For example, a simplified version of a conditional truth condition for an utterance u of “That is a cat” will say that for all x, if the utterer in uttering “that” in u thereby referred to x, u is true iff x is a cat. The conditional fact belongs to semantic knowledge; non-semantic knowledge is required to work out what the utterer referred to; the two kinds of knowledge conspire to enable a truth condition to be detached. The other kind of worry relates to difficult technical questions, relating to specific idioms, raised by context-dependence. I consider whether an argument by Travis (2006), designed to establish that there can be no correct truth conditional semantics, can be turned on its head, and used to establish a general method for bringing all forms of context-dependence within Davidsonʼs framework (using quantification into the qualifier “on understanding U”). I argue that this will not work, and that we are committed to a piecemeal examination of various cases, of which I give some examples. One of these relates directly to Travisʼs argument concerning the context-dependence of “grunt”. In addition, Davidsonians need to have a sharp eye for the distinction between pragmatic and semantic content, to be specified by a test akin to Griceʼs notion of cancelability; they should treat sentences like “Itʼs raining” by the conditional truth-condition method; and they should treat possessives as semantically very unspecific. It is part of the thesis of the paper that this list of examples by no means exhausts the cases a Davidsonian needs to address. (shrink)

The new Coronavirus, namely Sars-CoV-2, took the world by surprise and grew into a pandemic worldwide in a couple of months since the beginning of 2020.

This articles analyses four topics: 1. Restrictions imposed by the State and reactions by religious organizations. The theological-ethical response focused on the fact that all religions what to save lives and defeat death. 2. The pandemic shows the sensitive relation between the State and religions and shows the differences in power relations in the different countries. The theological-ethical response calls for a partnership between the State and the religions in their territory. 3. The relation between science and religion is tested during the pandemic. Whereas the majority of believers adhere to scientific results, a good part refuses scientific knowledge. The theological-ethical response of the authors is that science and religion are complementary and not contradictory. 4. Pandemics as situations of high uncertainty are often accompanied by conspiracy theories that claim to know who is guilty for the disaster, who is the scapegoat, which has to be punished. The theological-ethical response gives theological reasons to say no to conspiracies and scapegoats and yes to take responsibility wherever we are in order to save lives. (shrink)

As we know that during pandemic situation all classes for schools and colleges has been performed online .This mode of education has come in practice first time in life of students. Hence a level of depression and anxiety may develop in mind of under graduate college going students (...) who have been preparing for graduation and competitive exam. Going through the literature we found that the Hamilton Depression Scale & Hamilton Anxiety scale are suitable to measure Level of anxiety and depression .Both online and offline mode have been used to collect data from male and female candidate .A sample of 50 students male and 50 students have taken from Gwalior and nearby area . Two tailed T test has been done to analyze significant difference between the mean value of level of anxiety and level of depression as well for male and female candidate .Correlation coefficient has been determined to find the relation of variance between level of anxiety and level of depression between male and female students. SPSS software, Microsoft word and excel is use to arrange data, calculation, Tabulation and formation of chart. After data analysis and result and discussion it has concluded that the level of thinking and condition of living standard is almost same for male and female student in urban area .Hence there is no significant difference pertaining to level of anxiety and level of depression between male and female undergraduate student living in urban area. It is also come out that the There is no significance relation in level of anxiety and level of depression between male and female candidate. As we know that the corona virus has been spread in all over the world and so many people had lost their lives .In view of safety measure the government of India imposed lockdown of around 50 days in each part of country. All college and schools are closed and the final exams have also cancelled and many competitive exams have postponed. During this period of lock down undergraduate students have faced so many problems for continuing their study for their end semester exam and competitive exam as well .Due to uncertainty of their exams and their offline classes they experienced some level of depression and anxiety during this period .This project work is the assessment of level of depression and anxiety induced in male and female undergraduate students staying in urban area .

Cancel culture is a form of societal self-defense that becomes prominent particularly during periods of substantial moral upheaval. It can lead to the polarization of incompatible viewpoints if it is indiscriminately demonized. In this brief editorial letter, I consider framing cancel culture as an essentially contested concept (ECC), according to the theory of Walter B. Gallie, with the aim of establishing a groundwork for a more productive discourse on it. In particular, I propose that intermediate agreements and principles of reasonableness (...) can help refocus the debate on cancel culture towards democratic discourse, without blanket justification for every instance. In this context, asserting that cancel culture is an ECC does not dismiss the potential of achieving consensus on its shared core meaning or societal role. Like other similar ECCs, such as democracy or rule of law, it highlights the importance of contestations in shaping our collective understanding of the concept. (shrink)

In this article, I approach some phenomena seen predominantly on social-media sites that are grouped together as cancel culture with guidance from two major themes in Plato’s thought. In the first section, I argue that shame can play a constructive and valuable role in a person’s improvement, just as we see Socrates throughout Plato’s dialogues use shame to help his interlocutors improve. This insight can help us understand the value of shaming people online for, among other things, their morally reprehensible (...) views. In the second section, I argue that it is required for the proper functioning of democratic institutions that some views be excluded from the public sphere, which follows some Platonic ideas from the Laws. In neither case do I argue that this approach is good in an unqualified sense or even ultima facie good. However, I maintain that these important insights from Plato’s dialogues illuminate crucial aspects of how we should think about cancel culture. (shrink)

Explicatures are not cancellable. Theoretical considerations.

Many view cancellation as a method for holding influential personalities accountable for bad behavior, while others think cancelling amounts to censorship and bullying. I hold that neither of these accounts are worth pursuing, especially if the aim is social progress. In this paper, I offer a situated account of cancellation and cancel culture, locating the phenomenon in our exclusionary history while examining the social dynamics of belief. When we situate cancel culture, we can see how problematic instances of cancelling are (...) embedded in ignorance. While combatting ignorance appears to call for a remedy rooted in feminist standpoint epistemology, there are risks in adopting naive practices of deference. Applying criticisms of epistemic injustice and adopting Táíwò’s elite capture framework, I explain how well-intentioned cancelling can work against social movements. Since epistemic trust mechanisms discourage self-reflection and belief revision, the relevant tactics for enacting social change—coalition politics and education—seem out of reach. I conclude by sketching cancel culture as a diagnostic tool: cancellation can be used appropriately in marginalized communities, but when it comes to combatting ignorance among privileged folks, we should view cancel culture as a method for determining where our social institutions are failing us.

Empirical support is offered for the claim that the original Knobe effect, whereby our intentional action ascriptions exhibit certain asymmetries in light of our moral attitudes, can be successfully cancelled. This is predicted by the view that the Knobe effect can be explained in purely pragmatic terms (Adams and Steadman 2004a, 2004b, 2007). However, previous cancelling studies (Adams and Steadman 2007; Nichols and Ulatowski 2007) have failed to identify evidence of cancellability. The key to the successful cancelling strategy presented here (...) is to provide subjects with the opportunity to assent to statements that involve sufficiently strong forms of moral censure.

Several philosophers advance substantive theories of propositions, to deal with several issues they raise in connection with a concern with a long pedigree in philosophy, the problem of the unity of propositions. The qualification ‘substantive’ is meant to contrast with ‘minimal’ or ‘deflationary’ – roughly, views that reject that propositions have a hidden nature, worth investigating. Substantive views appear to create spurious problems by characterizing propositions in ways that make them unfit to perform their theoretical jobs. I will present in (...) this light some critical points against Hanks’ (2015, 2019) act-theoretic view, and Recanati’s (2019) recent elaboration of Hanks’ notion of cancellation. Both Hanks and Recanati, I’ll argue, rely on problematic conceptions of fiction and pretense. (shrink)

Several philosophers have recently claimed that if a proposition is cancellable from an uttered sentence then that proposition is not entailed by that uttered sentence. The claim should be a familiar one. It has become a standard device in the philosopher's tool-kit. I argue that this claim is false. There is a kind of entailment—which I call “modal entailment”—that is context-sensitive and, because of this, cancellable. So cancellability does not show that a proposition is not entailed by an uttered sentence. (...) I close the paper by describing an implication this has for a disagreement between J. L. Austin and Grice concerning the relation between felicity and truth. (shrink)

In this paper, new evidence is presented for the assumption that the reason-relation reading of indicative conditionals ('if A, then C') reflects a conventional implicature. In four experiments, it is investigated whether relevance effects found for the probability assessment of indicative conditionals (Skovgaard-Olsen, Singmann, and Klauer, 2016a) can be classified as being produced by a) a conversational implicature, b) a (probabilistic) presupposition failure, or c) a conventional implicature. After considering several alternative hypotheses and the accumulating evidence from other studies as (...) well, we conclude that the evidence is most consistent with the Relevance Effect being the outcome of a conventional implicature. This finding indicates that the reason-relation reading is part of the semantic content of indicative conditionals, albeit not part of their primary truth-conditional content. (shrink)

Genetic testing in the workplace is a technology both full of promise and fraught with ethical peril. Though not yet common, it is likely to become increasingly so.

Vor wenigen Tagen hat das Hamburger Kabarett-Theater Schmidts Tivoli die Zusammenarbeit mit dem Komiker Kay Ray beendet, offenbar weil rassistische Witze in der Show einen zentralen Platz einnehmen.

In this paper I argue that Miranda Fricker’s account of blame in “What’s the Point of Blame? A Paradigm Based Explanation” can assist in explaining why cancel culture is ultimately unproductive. In particular, the phenomenon of cancel culture possesses pathological forms of blame. There are three specific pathologies outlined by Fricker that can be observed in cancel culture. They are as follows: cancel culture does not leave room for people to learn from their mistakes, it does not express its blame (...) in the proper ethical register, and cancel culture allows for blame to fester and spread. In the first half of my paper, I will lay out the distinct aspects of Fricker’s paper that relate to cancel culture and a definition of the term cancel culture. In the second half, I will explore the real-life cancelation of actor Lea Michele so as to validate the presence of cancel culture in our society today. Furthermore, I will expand on three of Fricker’s pathologies that are present in cancel culture and refute a counter argument people may pose who are supportive of cancel culture. (shrink)

“Dutch Book” arguments and references to gambling theorems are typical in the debate between Bayesians and scientists committed to “classical” statistical methods.

I argue against the Ramsey test connecting indicative conditionals with conditional probability, by means of examples in which conditional probability is high but the conditional is intuitively implausible. At the end of the paper, I connect these issues to patterns of belief revision.

A new Evidence Test is applied to the problem of testing whether two Poisson random variables are dependent. The dependence structure is that of Holgate’s bivariate distribution. These bivariate distribution depends on three parameters, 0 < theta_1, theta_2 < infty, and 0 < theta_3 < min(theta_1, theta_2). The Evidence Test was originally developed as a Bayesian test, but in the present paper it is compared to the best known test of the hypothesis of independence in a (...) frequentist framework. It is shown that the Evidence Test is considerably more powerful when the correlation is not too close to zero, even for small samples. (shrink)

While ‘cancel culture’ is commonly regarded as limiting freedom of speech and artistic freedom, this article proposes a new understanding of ‘cancel culture’ as emancipatory norm-setting that is key for democratization. On a non-governmental level of the self-regulation of the art world, the argument for artistic freedom ignores the fact that art is permeated by power. The introduction of ‘politically correct’ norms leads to a justified redistribution of such power. On a parastatal level of public broadcasting and state cultural funding, (...) neutrality is necessary but should be understood materially to include marginalized voices. Restrictions of freedom of speech and artistic freedom do occur on the state-level of hate-speech regulation.

The Turing Test (TT), the Chinese Room Argument (CRA), and the Symbol Grounding Problem (SGP) are about the question “can machines think?” We propose to look at these approaches to Artificial Intelligence (AI) by showing that they all address the possibility for Artificial Agents (AAs) to generate meaningful information (meanings) as we humans do. The initial question about thinking machines is then reformulated into “can AAs generate meanings like humans do?” We correspondingly present the TT, the CRA and the (...) SGP as being about generation of human-like meanings. We model and address such possibility by using the Meaning Generator System (MGS) where a system submitted to an internal constraint generates a meaning in order to satisfy the constraint. The system approach of the MGS allows comparing meaning generations in animals, humans and AAs. The comparison shows that in order to have AAs capable of generating human-like meanings, we need the AAs to carry human constraints. And transferring human constraints to AAs raises concerns coming from the unknown natures of life and human mind which are at the root of human constraints. Implications for the TT, the CRA and the SGP are highlighted. It is shown that designing AAs capable of thinking like humans needs an understanding about the natures of life and human mind that we do not have today. Following an evolutionary approach, we propose as a first entry point an investigation about the possibility for extending a “stay alive” constraint into AAs. Ethical concerns are raised from the relations between human constraints and human values. Continuations are proposed.

Which animals have conscious experiences? Many different, diverse and unrelated behaviors and cognitive capacities have been proposed as tests of the presence of consciousness in an animal. It is unclear which of these tests, if any, are valid. To remedy this problem, I develop a list consisting of eight desiderata which can be used to assess putative tests of animal consciousness. These desiderata are based either on detailed analogies between consciousness-linked human behavior and non-human behavior, on theories of consciousness or (...) on methods from human consciousness science. If a test or set of tests satisfies more of these desiderata, passing it provides stronger evidence of consciousness. Moreover, one can design future tests of animal consciousness with the intention of satisfying these desiderata to ensure their evidential strength. (shrink)

In this research, we focus on the usage of adversarial sampling to test for the fairness in the prediction of deep neural network model across different classes of image in a given dataset. While several framework had been proposed to ensure robustness of machine learning model against adversarial attack, some of which includes adversarial training algorithm. There is still the pitfall that adversarial training algorithm tends to cause disparity in accuracy and robustness among different group. Our research is aimed (...) at using adversarial sampling to test for fairness in the prediction of deep neural network model across different classes or categories of image in a given dataset. We successfully demonstrated a new method of ensuring fairness across various group of input in deep neural network classifier. We trained our neural network model on the original image, and without training our model on the perturbed or attacked image. When we feed the adversarial samplings to our model, it was able to predict the original category/ class of the image the adversarial sample belongs to. We also introduced and used the separation of concern concept from software engineering whereby there is an additional standalone filter layer that filters perturbed image by heavily removing the noise or attack before automatically passing it to the network for classification, we were able to have accuracy of 93.3%. Cifar-10 dataset have ten categories of dataset, and so, in order to account for fairness, we applied our hypothesis across each categories of dataset and were able to get a consistent result and accuracy.

Apparently, I’m a righteous son of a bitch, morally speaking. At least that’s the conclusion I would have to reach if I trusted the results of a morality test I took at the BBC website (bbc.co.uk/labuk/experiments/morality).

Briefly, the idea is that “we, as individuals, behave as if we are part of a bigger ‘superorganism’ (...) when we are organised into large social groups, as in cities or societies. ... all moral actions are based on the fundamental need to ‘police’ society in order to keep the ‘superorganism’ functioning properly.”.

A failed market, or asymmetric information, is a well-known economic concept. This phenomenon can be witnessed in a variety of markets. However, the repercussions of information asymmetry are thought to be more substantial in the stock market. Because, in addition to measurable economic impact, knowledge asymmetry harms trust. The Vietnamese stock market has experienced several successes since its creation, yet it still has many restrictions typical of a young market. The numerous violations of the subjects on the market in recent (...) years reflect those restrictions. Information issues, or more broadly, information asymmetry, are primarily responsible for these errors. The goal of this study was to analyze and assess the degree of information asymmetry in the Vietnamese stock market during a five-year period (2018 – 2022). The author tests the information asymmetry effect using GARCH models for VN-Index data and measures Adverse Selection Component (ASC) using the Glosten & Harris model for the 100 largest capitalization companies on the Ho Chi Minh City Stock Exchange (HOSE). The findings demonstrate information asymmetry, and the ASC value for the entire study period is 89.53%. This empirical finding serves as the foundation for formulating suitable policy recommendations for every market participant, aiding in the growth of a productive, equitable, open, and transparent Vietnamese stock market.

On a literal reading of `Computing Machinery and Intelligence'', Alan Turing presented not one, but two, practical tests to replace the question `Can machines think?'' He presented them as equivalent. I show here that the first test described in that much-discussed paper is in fact not equivalent to the second one, which has since become known as `the Turing Test''. The two tests can yield different results; it is the first, neglected test that provides the more appropriate (...) indication of intelligence. This is because the features of intelligence upon which it relies are resourcefulness and a critical attitude to one''s habitual responses; thus the test''s applicablity is not restricted to any particular species, nor does it presume any particular capacities. This is more appropriate because the question under consideration is what would count as machine intelligence. The first test realizes a possibility that philosophers have overlooked: a test that uses a human''s linguistic performance in setting an empirical test of intelligence, but does not make behavioral similarity to that performance the criterion of intelligence. Consequently, the first test is immune to many of the philosophical criticisms on the basis of which the (so-called) `Turing Test'' has been dismissed. (shrink)

The full Bayesian signi/cance test (FBST) for precise hypotheses is presented, with some illustrative applications. In the FBST we compute the evidence against the precise hypothesis. We discuss some of the theoretical properties of the FBST, and provide an invariant formulation for coordinate transformations, provided a reference density has been established. This evidence is the probability of the highest relative surprise set, “tangential” to the sub-manifold (of the parameter space) that defines the null hypothesis.

Dicke and Schiff established a framework for testing general relativity, including through null experiments and using the physics of space exploration, electronics and condensed matter, such as the Pound-Rebka experiment and laser interferometry. The gravitational lens tests and the temporal delay of light are highlighted by parameter γ of the PPN formalism, equal to 1 for general relativity and with different values in other theories. The BepiColombo mission aims to test the general theory of relativity by measuring the gamma (...) and beta parameters of the PPN formalism. DOI: 10.13140/RG.2.2.25673.70240. (shrink)

The Turing Test is one of the most disputed topics in artificial intelligence, philosophy of mind, and cognitive science. This paper is a review of the past 50 years of the Turing Test. Philosophical debates, practical developments and repercussions in related disciplines are all covered. We discuss Turing's ideas in detail and present the important comments that have been made on them. Within this context, behaviorism, consciousness, the 'other minds' problem, and similar topics in philosophy of mind are (...) discussed. We also cover the sociological and psychological aspects of the Turing Test. Finally, we look at the current situation and analyze programs that have been developed with the aim of passing the Turing Test. We conclude that the Turing Test has been, and will continue to be, an influential and controversial topic. -/- (This paper was reprinted in: The Turing Test: The Elusive Standard of Artificial Intelligence, J.

A letter replying to Bayne et al. "Tests for consciousness in humans and beyond", 2024, arguing that the search for consciousness "beyond" healthy adult humans should begin with other animals.

Le test primordial de toute théorie quantique de la gravité est la reproduction des succès de la relativité générale. Cela implique de reconstruire la géométrie locale à partir des observables non locaux. De plus, la gravité quantique devrait probablement prédire la topologie à grande échelle de l'Univers, qui pourrait bientôt être mesurable , et les phénomènes à l'échelle de Planck. Il existe déjà une prédiction liée à la gravité quantique: l'existence et le spectre du rayonnement Hawking du trou noir, (...) une prédiction « semi-classique » résultant de la théorie des champs quantiques sur un fond incurvé fixe, et confirmée ensuite théoriquement . On suppose qu'une théorie de la gravité qui ne reproduira pas cette prédiction est erronée. DOI: 10.13140/RG.2.2.11424.40965 . (shrink)

-/- For all that digital methods—including network visualization, text analysis, and others—have begun to show extensive promise in philosophical contexts, a tension remains between two uses of those tools that have often been taken to be incompatible, or at least to engage in a kind of trade-off: the discovery of new hypotheses and the testing of already-formulated positions. This paper presents this basic distinction, then explores ways to resolve this tension with the help of two interdisciplinary case studies, taken from (...) preregistration in contemporary science and the debate over whig history in the history of science. These case studies, the paper argues, refocus our attention from a mutually exclusive testing/discovery binary to the relationship between our background data or philosophical views and the empirical generalizations that we might draw from the data. Finally, it develops a set of three challenges for philosophers and corresponding avenues for future work that will, it is hoped, allow us to better justify our use of these methods. (shrink)
