Does ethics have adequate general theories? Our analysis shows that this question does not have a straightforward answer since the key terms are ambiguous. So we should not concentrate on the answer but on the question itself. “Ethics” stands for many things, but we let that pass. “Adequate” may refer to varied arrays of methodological principles which are seldom fully articulated in ethics. “General” is a notion with at least three meanings. Different kinds of generality may be at cross-purposes, so (...) we must not expect theories to be general in sundry senses. “Theory,” for that matter, is itself ambiguous. Some thinkers say that ethics cannot have theories, while others deny it. We doubt whether opposing parties are talking about the same things.No wonder, then, that controversies in ethics are long-lasting and unproductive. We hope that the methodology we have presented will alleviate some of them. The examples we chose show that this is feasible. Views such as Hare's and Jonsen and Toulmin's which are seemingly wide apart, show convergence if we put them in a methodological perspective.Our analysis also suggests that many alleged differences between science and ethics could fade away if methodology is brought to bear on them. Specifically, the idea that ethics compares poorly with science in view of limited generality, or poor means of justification, is unfounded. Those who defend this view over-rate the powers of science. (shrink)

The problem of evil is set out as a dialectic between theist and critic, the aim being to reveal the place of ethical judgments in the theist's apology. I discover what ethical judgments, both normative and descriptive, are implicit in the theist's use of his premises as good reasons, and where his reasoning goes astray. I suggest what ethical judgments, in contrast to the theist's, are supported by good reasons.

This book is a thesis submitted to the Faculty of Arts of the University of Utrecht. It was prepared under the supervision of Prof. Dr. H. Schultink. I would like to express my gratitude to him for his criticisms of earlier versions which led to many improvements, in particular with respect to the exposition of the argument. To my co-referent Dirk van Dalen, reader in the Department of Philo sophy (,Centrale Interfaculteit') of the University of Utrecht, I am greatly indebted (...) for his valuable and fruitful suggestions about problems relevant to both linguistics and logic. Several ideas developed in this study owe their present concrete form to our many discussions. This thesis originates in syntactic research into the Aspects carried out in 1967 under the supervision of Albert Kraak, professor at the University of Nijmegen, who ever since gave much attention to my work in progress. I am very grateful to him for his careful and stimulating criticism as well as for the continuous support he gave me during these years. The present study closely relates to the work of my colleague Wim Klooster with regard to both its theoretical framework and its subject matter. Our joint work on the measurement of duration in Dutch is an integral part of the argument. I have greatly profited from the numerous discussions we have had. (shrink)

Abstract: Artificial Intelligence (AI) is transforming the agricultural sector, enhancing both productivity and sustainability. This paper delves into the impact of AI technologies on agriculture, emphasizing their application in precision farming, predictive analytics, and automation. AI-driven tools facilitate more efficient crop and resource management, leading to higher yields and a reduced environmental footprint. The paper explores key AI technologies, such as machine learning algorithms for crop monitoring, robotics for automated planting and harvesting, and data analytics for optimizing resource use. Additionally, (...) it discusses challenges like data privacy, barriers to technology adoption, and the ethical implications of AI in farming. Integrating AI into agricultural practices holds the promise of greater efficiency and sustainability, paving the way for future innovations. (shrink)

There has been a call for a potentially revolutionary change to our existing understanding of the psychological concept of personal identity. Apparently, people can psychologically represent people, including themselves, as multiple individuals at the same time. Here we ask whether the intransitive judgments found in these studies truly reflect the operation of an intransitive concept of personal identity. We manipulate several factors that arbitrate between transitivity and intransitivity and find most support for transitivity: in contrast to prior work, most participants (...) do not make intransitive judgments when there is any reason to favor one individual over another. People change which single individual they personally identify with, depending on which individual competes more strongly or weakly for identity, rather than identifying with both individuals. Even when two individuals are identical and therefore both entitled to be the same person, we find that people make more transitive judgments once they understand the practical commitments of their responses (Experiment 4), and report not being able to actually imagine two perspectives simultaneously when reasoning about the scenario (Experiment 5). In short, we suggest that while people may make intransitive judgments, these do not reflect that they psychologically represent identity in an intransitive manner. (shrink)

Environmental philosophy – broadly conceived as using philosophical tools to develop ideas related to environmental issues – is conducted and practised in highly diverse ways in different contexts and traditions in Asia. ‘Asian environmental philosophy’ can be understood to include Asian traditions of thought as well as grassroots perspectives on environmental issues in Asia. Environmental issues have sensitive political facets tied to who has the legitimacy to decide about how natural resources are used. Because of this, the works, practices, and (...) researchers in Asian environmental philosophy are exposed to being (mis)used by diverse stakeholders and actors to support political ends not related to environmental sustainability. Two processes are at play at the nexus of the construction of identities in relation to conceptualisations of nature: eco-orientalism and ecological nationalisms. This paper analyzes and exemplifies these dynamics through a conceptual framework that distinguishes ideological and socio-technical explanations of environmental degradation. Finally, to minimise the risks of political misuse, five pathways are presented to carefully help curate environmental, philosophical statements: contextualise, quantify uncertainty and ‘uniqueness’, downscale, confront claims with local realities and literature, and collaborate with researchers from other disciplines. Conjointly, these pathways aim at favouring intercultural collaboration while valuing diversity, thus supporting the development and exchanges in environmental philosophy in Asia and beyond.

This analysis summarizes conclusions on an evolutionary model for the origin of moral and religious capacities in the genus Homo. The authors’ published model (2020, Routledge) is now extended to the emergence of nascent theological thinking, augmenting the previous line of theory based on genomics, cognitive science, neuroscience, paleoneurology, cognitive archaeology, ethnography, and modern social science. This analysis concludes that findings support the earliest theological thinking in Homo sapiens, but not in an earlier species, Homo erectus, and clarifies why and (...) when it likely began. Types of anatomy, behavior, neurology, and cognition are presented that support tendencies to frame a structure of religious principles and a set of supernatural figures that early humans would consider right, just, exemplary, and even sacred. Stages of emergent physical, behavioral, and cognitive features are presented in tables. While based on published research results in the sciences, the model is presented here with anticipation of future testing. (shrink)

Abstract: The integration of Artificial Intelligence (AI) into medical imaging marks a transformative advancement in healthcare, significantly enhancing diagnostic accuracy, efficiency, and patient outcomes. This paper delves into the application of AI technologies in medical image analysis, with a particular focus on techniques such as convolutional neural networks (CNNs) and deep learning models. We examine how these technologies are employed across various imaging modalities, including X-rays, MRIs, and CT scans, to improve disease detection, image segmentation, and diagnostic support. Furthermore, the (...) paper discusses the challenges associated with AI-driven medical imaging, such as data quality, model interpretability, and ethical considerations. By analyzing recent advancements and real-world case studies, this paper offers insights into the current landscape of AI in medical imaging and explores its potential future directions. The findings underscore the ongoing evolution of AI technologies and their pivotal role in advancing medical diagnostics and treatment strategies. (shrink)

This paper argues that higher-order doubt generates an epistemic dilemma. One has a higher-order doubt with regards to P insofar as one justifiably withholds belief as to what attitude towards P is justified. That is, one justifiably withholds belief as to whether one is justified in believing, disbelieving, or withholding belief in P. Using the resources provided by Richard Feldman’s recent discussion of how to respect one’s evidence, I argue that if one has a higher-order doubt with regards to P, (...) then one is not justified in having any attitude towards P. Otherwise put: No attitude towards the doubted proposition respects one’s higher-order doubt. I argue that the most promising response to this problem is to hold that when one has a higher-order doubt about P, the best one can do to respect such a doubt is to simply have no attitude towards P. Higher-order doubt is thus much more rationally corrosive than non-higher-order doubt, as it undermines the possibility of justifiably having any attitude towards the doubted proposition. (shrink)

The writings of Joseph Henry Woodger (1894–1981) are often taken to exemplify everything that was wrongheaded, misguided, and just plain wrong with early twentieth-century philosophy of biology. Over the years, commentators have said of Woodger: (a) that he was a fervent logical empiricist who tried to impose the explanatory gold standards of physics onto biology, (b) that his philosophical work was completely disconnected from biological science, (c) that he possessed no scientific or philosophical credentials, and (d) that his work was (...) disparaged – if not altogether ignored – by the biologists and philosophers of his era. In this paper, we provide the first systematic examination of Woodger’s oeuvre, and use it to demonstrate that the four preceding claims are false. We argue that Woodger’s ideas have exerted an important influence on biology and philosophy, and submit that the current consensus on his legacy stems from a highly selective reading of his works. By rehabilitating Woodger, we hope to show that there is no good reason to continue to disregard the numerous contributions to the philosophy of biology produced in the decades prior to the professionalization of the discipline.

The Abrahamic traditions regard God as the world’s author. But what kind of author? A novelist? A playwright? Perhaps a composer of classical music? I will argue that it is best to regard God as like an improvisational play director or the leader of a jazz ensemble. Each determines the broad melodic contours or coarse-grained plot beforehand, while allowing their musicians or actors, and chance, to fill in the more fine-grained details. This analogy allows us to regard God as the (...) ultimate author of this world, while allowing us to be, while less than co-authors, more than mere enactors of a pre-written piece. These metaphors are particularly well-suited to illustrate and flesh out an Open Theistic view of things. (shrink)

Abstract: The incorporation of Artificial Intelligence (AI) into educational technology has dramatically transformed learning through Intelligent Tutoring Systems (ITS). These systems utilize AI to offer personalized, adaptive instruction tailored to each student's needs, thereby improving learning outcomes and engagement. This paper examines the development and impact of ITS, focusing on AI technologies such as machine learning, natural language processing, and adaptive algorithms that drive their functionality. Through various case studies and applications, it illustrates how ITS have revolutionized traditional educational methods (...) and addresses the challenges and limitations, including data privacy and system biases. The discussion also covers future directions in ITS development, highlighting emerging trends and potential advancements. The goal is to provide a thorough understanding of how ITS use AI to enhance educational experiences and suggest avenues for future research in this evolving field. (shrink)

This systematic literature review examines the effectiveness of Grammarly as an Automated Writing Evaluation (AWE) tool for improving the writing skills of English as a Second Language (ESL) and English as a Foreign Language (EFL) students. Drawing on 10 studies published between 2018 and 2024, the review assesses Grammarly’s key features, benefits, and limitations. Results show that Grammarly significantly reduces grammatical errors, enhances students’ writing confidence, and fosters autonomous learning. However, challenges such as over-reliance on the tool and its limited (...) capacity to provide comprehensive feedback on higher-order writing skills remain. The review underscores the need for further research into Grammarly’s long-term effects on writing development, particularly its efficacy across various academic disciplines and contexts. (shrink)

Plagiarism detection is the process of finding similarities on electronic based documents. Recently, this process is highly required because of the large number of available documents on the internet and the ability to copy and paste the text of relevant documents with simply Control+C and Control+V commands. The proposed solution is to investigate and develop an easy, fast, and multi-language support plagiarism detector with the easy of one click to detect the document plagiarism. This process will be done with the (...) support of intelligent system that can learn, change and adapt to the input document and make a cross-fast search for the content on the local repository and the online repository and link the content of the file with the matching content everywhere found. Furthermore, the supported document type that we will use is word, text and in some cases, the pdf files –where is the text can be extracting from them- and this made possible by using the DLL file from Word application that Microsoft provided on OS. The using of DLL will let us to not constrain on how to get the text from files; and will help us to apply the file on our Delphi project and walk throw our methodology and read the file word by word to grantee the best working scenarios for the calculation. In the result, this process will help in the uprising the documents quality and enhance the writer experience related to his work and will save the copyrights for the official writer of the documents by providing a new alternative tool for plagiarism detection problem for easy and fast use to the concerned Institutions for free.

Structural analogies connect Williamson’s epistemology and action theory: for example, action is the direction-of-fit mirror image of knowledge, and knowledge stands to belief as action stands to intention. These structural analogies, for Williamson, are meant to illuminate more generally how ‘mirrors’ reversing direction of fit should be understood as connecting the spectrum of our cognitive and practically oriented mental states. This paper has two central aims, one negative and the other positive. The negative aim is to highlight some intractable problems (...) with Williamson’s preferred analogical picture, which links the cognitive and the practical through the nexus of direction-of-fit mirroring. The positive aim of the paper is to propose a better alternative. In particular, we show that an achievement-theoretic proposal captures what is in common across the range of attitudes that exhibit the kind of structure that knowledge-belief, action-desire/intention do, while at the same time avoiding the problems shown to face Williamson’s proposed picture. Moreover, we draw attention to several key theoretical benefits of embracing our proposed achievement-theoretic picture, including some of the key benefits of the knowledge-first programme that Williamson’s own analogies were designed to secure.

Many classically valid meta-inferences fail in a standard supervaluationist framework. This allegedly prevents supervaluationism from offering an account of good deductive reasoning. We provide a proof system for supervaluationist logic which includes supervaluationistically acceptable versions of the classical meta-inferences. The proof system emerges naturally by thinking of truth as licensing assertion, falsity as licensing negative assertion and lack of truth-value as licensing rejection and weak assertion. Moreover, the proof system respects well-known criteria for the admissibility of inference rules. Thus, supervaluationists (...) can provide an account of good deductive reasoning. Our proof system moreover brings to light how one can revise the standard supervaluationist framework to make room for higher-order vagueness. We prove that the resulting logic is sound and complete with respect to the consequence relation that preserves truth in a model of the non-normal modal logic _NT_. Finally, we extend our approach to a first-order setting and show that supervaluationism can treat vagueness in the same way at every order. The failure of conditional proof and other meta-inferences is a crucial ingredient in this treatment and hence should be embraced, not lamented. (shrink)

In this chapter, we argue that the web is a poietically- enabling environment, which both enhances and requires the development of a “constructionist ethics”. We begin by explaining the appropriate concept of “constructionist ethics”, and analysing virtue ethics as the primary example. We then show why CyberEthics (or Computer Ethics, as it is also called) cannot be based on virtue ethics, yet needs to retain a constructionist approach. After providing evidence for significant poietic uses of the web, we argue that (...) ethical constructionism is not only facilitated by the web, but is also what the web requires as an ethics of the digital environment. In conclusion, we relate the present discussion to standard positions in CyberEthics and to a broader project for Information Ethics. (shrink)

This research paper presents the development and evaluation of an expert system for diagnosing kidney diseases.

We explain and explore class-theoretic potentialism—the view that one can always individuate more classes over a set-theoretic universe. We examine some motivations for class-theoretic potentialism, before proving some results concerning the relevant potentialist systems (in particular exhibiting failures of the $\mathsf {.2}$ and $\mathsf {.3}$ axioms). We then discuss the significance of these results for the different kinds of class-theoretic potentialists.

This mixed methods study aims to determine the effects of the developed Gradual Release of Responsibility Instructional Model (GRRIM) learning module on the academic achievement of Grade 9 students in Geometry. The topic chosen for the module development is one of the students’ identified least learned competencies, particularly in parallelograms and their properties. The study participants were five (5) module development experts and 110 students grouped into control and experimental groups. The control group was exposed to DepEd SLM, while the (...) experimental group was exposed to GRRIM LM. Data were analyzed using thematic analysis, mean, independent samples t-test, and ANCOVA. The results of the thematic analysis of the focus group discussion revealed a module’s characteristics that embody the GRRIM approach’s different stages. Furthermore, findings indicated that after the intervention, the experimental group’s post-test mean scores were found to be at a moderate level. In contrast, the control group remained at a low level. Finally, the study revealed that when pre-test mean scores were treated as a covariate, there was a significant difference in the post-test mean scores between the control and experimental groups. The findings revealed that the students exposed to GRRIM LM performed better than those exposed to DepEd SLM. (shrink)

Anecdotal checklists are becoming more and more common in psychological practice nowadays, but they are not frequently employed in clinical psychology. This study focused on the use of anecdotal checklists in clinical practice and highlighted the experiences, perceptions, potential barriers, and challenges of the use of anecdotal checklists. A case study design was utilized in this study with one participant who utilized the anecdotal checklist during the intervention. The data was gathered through interviews and was analyzed using thematic analysis. Data (...) revealed that the participant expressed improved session structure and overwhelming paperwork and forms management. The participant perceived that using the checklist results in an effective collaboration and intervention. Moreover, challenges involve establishing the psychometric soundness of the checklist. The study highlights the potential benefits of using anecdotal checklists in providing psychological services. Additionally, the study emphasizes the need for further research focusing on the establishment of the psychometric properties of the checklist. (shrink)

In this chapter, we consider ethical and philosophical aspects of trust in the practice of medicine. We focus on trust within the patient-physician relationship, trust and professionalism, and trust in Western (allopathic) institutions of medicine and medical research. Philosophical approaches to trust contain important insights into medicine as an ethical and social practice. In what follows we explain several philosophical approaches and discuss their strengths and weaknesses in this context. We also highlight some relevant empirical work in the section on (...) trust in the institutions of medicine. It is hoped that the approaches discussed here can be extended to nursing and other topics in the philosophy of medicine. (shrink)

Minimalism about truth is one of the main contenders for our best theory of truth, but minimalists face the charge of being unable to properly state their theory. Donald Davidson incisively pointed out that minimalists must generalize over occurrences of the same expression placed in two different contexts, which is futile. In order to meet the challenge, Paul Horwich argues that one can nevertheless characterize the axioms of the minimalist theory. Sten Lindström and Tim Button have independently argued that Horwich’s (...) attempt to formulate minimalism remains unsuccessful. We show how to properly state Horwich’s axioms by appealing to propositional functions that are given by definite descriptions. Both Lindström and Button discuss proposals similar to ours and conclude that they are unsuccessful. Our new suggestion avoids these objections. (shrink)

The Philippines is a multicultural society with diverse cultures and beliefs for each indigenous community. This study was designed to determine the level of culturally responsive teaching self-efficacy (CRTSE) of mathematics teachers and to propose a training design. The study utilized an explanatory sequential research design using a survey and focus-grouped discussion and was participated by 65 in-service mathematics teachers. Based on the result, the mathematics teachers' overall level of teaching efficacy in using culturally responsive pedagogy (CRP) is very high. (...) It was also found that teachers’ implementation of CRP that influences teaching self-efficacy includes the use of native language and the use of contextualized and localized examples. It is recommended that mathematics teachers may adopt the use of culturally responsive pedagogies in their respective classes and consider the use of native language and use of contextualized and localized examples to provide a meaningful teaching-learning experience. -/- .

Conservation can occur anywhere regardless of scale, political jurisdiction, or landownership. We present a framework to help managers at protected areas practice conservation at the scale of relationships. We focus on relationships between stakeholders and protected areas and between managers and other stakeholders. We provide a synthesis of key natural resources literature and present a case example to support our premise and recommendations. The purpose is 4-fold: 1) discuss challenges and threats to conservation and protected areas; 2) outline a relationship-scale (...) approach to address conservation threats; 3) describe the tools and techniques that can be used to implement this approach; and 4) present a case example from rural Alaska, USA, to illustrate relationship-scale conservation. Our case example illustrates how aspects of this approach to conservation were applied to address a wildlife population decline. Tools needed to implement relationship-scale conservation include 1) collecting and documenting narratives of place; 2) measuring and monitoring trust and commitment; and 3) identifying and mitigating threats. We recommend that planners and managers, working with their research partners, redefine and refocus their goals and objectives to include these practices. Doing so will enable them to gain substantial applied knowledge about their stakeholders and foster and maintain place relationships as desired outcomes of conservation. The ultimate outcome is a better prognosis for long-term global survival of protected areas and biodiversity. Published 2014.

Assurance theories of testimony attempt to explain what is distinctive about testimony as a form of epistemic warrant or justification. The most characteristic assurance theories hold that a distinctive subclass of assertion (acts of “telling”) involves a real commitment given by the speaker to the listener, somewhat like a promise to the effect that what is asserted is true. This chapter sympathetically explains what is attractive about such theories: instead of treating testimony as essentially similar to any other kind of (...) evidence, they instead make testimonial warrant depend on essential features of the speech act of testimony as a social practice. One such feature is “buck-passing,” the phenomenon that when I am challenged to defend a belief I acquired through testimony, I may respond by referring to the source of my testimony (and thereby “passing the buck”) rather than providing direct evidence for the truth of the content of the belief. The chapter concludes by posing a serious challenge to assurance theories, namely that the social practice of assurance insufficiently ensures the truth of beliefs formed on the basis of testimony, and thereby fails a crucial epistemological test as a legitimate source of beliefs.

Translated into Danish by Henrik Jøker Bjerre.

Part of John Andrew Rice’s legacy, besides being a founder of Black Mountain College, is his vision of what a small liberal arts college curriculum should be. This vision helps shed light on some possible avenues by which to answer the following important questions: What implications do John Dewey’s progressive educational ideas have for experimenting with curricular design at small colleges? Does the college teacher’s struggle for improvement or growth depend on her having a belief that there is an ideal (...) liberal arts college curriculum? Probably the best known of such ready-made curricula is the Great Books Program, which employs a list of classic primary-source texts as the entry point into highly engaged dialogue, scholarship and learning guided by a teacher or tutor. In order to answer these questions, the paper turns to the historical debate between John Dewey and Robert Maynard Hutchins over the relative merits of progressive educational ideals and the Great Books approach. Most who have commented on this debate emphasize the differences between Dewey and Hutchins’ views.[ii] While Dewey emphasized learning through practical problem solving, in a dynamic mix of subject matter and method, Hutchins stressed exposure to and discussion of at least one-hundred primary texts in the Western canon, from Plato and Aristotle to Emerson and J.S. Mill. Hutchins resisted what he saw as the progressive educator’s push to transform the proper end of educating the whole person into training her for a particular vocation. In response, Dewey criticized Hutchins’ insistence that there existed a “hierarchy of truths” and that higher learning should remain aloof to the concerns of everyday life. Few commentators, however, mention the significant areas of agreement between the pedagogical approaches of Dewey and Hutchins, as well as other Great Books scholars. Since Rice praised the ideas of at least one Great Books proponent (Stringfellow Barr of St. John’s College), a more positive reconstruction of the Dewey-Hutchins exchange helps us to see how Dewey’s ideas informed Rice’s vision for the experimental college at Black Mountain—or so I argue.[iii].

In Against Purity, Alexis Shotwell takes up a multiplicity of tasks with respect to what I think of as non-ideal ethical theory. In what follows, I trace the relationship of her work to that of non-ideal theorists whose work influences mine. Then, more critically, I probe her analysis of gender voluntarism in Chapter 5, “Practicing Freedom: Disability and Gender Transformation,” partly to better understand what she takes it to be, and partly to advance a cautious defense of some of the (...) moral functions of individualistic performances of gender voluntarism that non-ideal theory leads me to value. I conclude that my interest in retaining a positive account of individualistic gender voluntarism as a form of resistance to a hostile world is due to my tendency to take non-ideal theory as a recommendation for some pessimism, whereas Shotwell’s similar commitments turn out to inform her more optimistic philosophy.

Vaccination complacency occurs when perceived risks of vaccine-preventable diseases are sufficiently low so that vaccination is no longer perceived as a necessary precaution. Disease outbreaks can once again increase perceptions of risk, thereby decrease vaccine complacency, and in turn decrease vaccine hesitancy.

Constitutive reflexivity, stories, and personal narrative were used to interpret leisure experience and provide insights for understanding leisure identity. I present a personal narrative of an annual canoe camping trip on a forested backcountry river.

The author illustrates how personal narrative allows opportunities for understanding and interpreting meanings and changing leisure identities.

The purpose is to bring the writer/researcher into the qualitative project as a subject and actor in the story and show how leisure identity images are created and affirmed through time. (shrink)

The dominant approach to the study of dynamic preference is to generate preference change by manipulating aspects of decision-problem presentation (problem description, task procedure, contextual options). The predisposing approach instead manipulates the decision maker’s mental state while holding problem presentation constant. Three illustrative studies are outlined here. The first modified preferences for ambitious consumption by manipulating subjects’ consumption energy. The second modified preferences for immediate consumption by manipulating subjects’ hedonic resources. The third modified preferences for consumption itself by manipulating subjects’ (...) desire proneness. Whereas framing is thought to affect perception, predisposing apparently can affect tastes and so involves a special kind of preference dynamism. (shrink)

We consider several natural fragments of the alternating-time temporal logics ATL* and ATL with restrictions on the nesting between temporal operators and strategic quantifiers. We develop optimal decision procedures for satisfiability in these fragments, showing that they have much lower complexities than the full languages. In particular, we prove that the satisfiability problem for state formulae in the full `strategically flat' fragment of ATL* is PSPACE-complete, whereas the satisfiability problems in the flat fragments of ATL and ATL$^{+}$ are $\Sigma^P_3$-complete. We (...) note that the nesting hierarchies for fragments of ATL* collapse in terms of expressiveness above nesting depth 1, hence our results cover all such fragments with lower complexities.

I defend an account of Moore's conception of Common Sense—as it figures in "A Defence of Common Sense"—according to which it is based in a vision of the community of human beings as bound and unified by a settled common understanding of the meaning of our words and statements. This, for Moore, is our inalienable starting point in philosophy. When Moore invokes Common Sense against idealist (and skeptical) philosophers, he is reminding them that they too are bound by this common (...) understanding, which cannot just be left behind as they confusedly believe. On Moore's conception, Common Sense becomes nothing other than the affirmation that there is such a common understanding—that there is Common Sense—which yields a specific body of Common Sense knowledge. This yields a more principled account of Common Sense than a mere tallying of what contingently happens to be believed (or known) by all. (shrink)

I investigate why Frege rejected the theory of types, as Russell presented it to him in their correspondence. Frege claims that it commits one to violations of the law of excluded middle, but this complaint seems to rest on a dogmatic refusal to take Russell’s proposal seriously on its own terms. What is at stake is not so much the truth of a law of logic, but the structure of the hierarchy of the logical categories, something Frege seems to neglect. (...) To come to a better understanding of Frege’s response, I proceed to investigate his conception of the nature of the logical categories, and how it differs from Russell’s. I argue that, for Frege, our grasp of the logical categories cannot be severed from our grasp of the Begriffsschrift notation itself. Russell, on the other hand, attaches no such importance to notation. From Frege’s point of view, Russell has not succeeded in presenting an alternative conception of the logical hierarchy, since such a conception must go in tandem with the development of a notation. Moreover, Frege has good reasons to think that Russell’s proposal does not admit of a suitable notation. (shrink)

I argue that no successful version of Williamson's anti‐luminosity‐argument has yet been presented, even if Srinivasan's further elaboration and defence is taken into account. There is a version invoking a coarse‐grained safety condition and one invoking a fine‐grained safety condition.

Similar problems arise for the fine‐grained version. Moreover, I argue that Srinivasan's (...) defence of the more contentious fine‐grained safety condition is also unsuccessful, again for similar reasons. (shrink)

This paper critically discusses Hacker’s reading of nonsense in Wittgenstein’s Tractatus in terms of his notion of misuse, which is taken to consist in the violation of rules of logical syntax. I argue that Hacker’s reading relies on an equivocation between sign and symbol: what is ‘misused’ is a mere sign, but the verdict of nonsensicality relies on seeing it as a symbol. Although Hacker seeks to distance himself from resolute readings – according to which nonsense always consists in nothing (...) but a failure to assign meaning to one’s sentences – I argue that his own verdicts of nonsensicality have their ultimate grounds in exactly the same sort of assessment, i.e. whether meaning has been assigned to a sentence. The rules of logical syntax, contrary to his own intentions, do no real work in determining whether a sentence is nonsensical or not. (shrink)
