Grice bu yazıda temel olarak sezdirim kavramını incelemektedir. Sezdirim bir karşılıklı konuşmada konuşucunun, söylediği şey ötesinde dinleyicisine aktardığı düşüncedir. Konuşma sezdirimleri söz konusu olduğunda dinleyici, bir çıkarım sonucunda sezdirimleri saptar. Grice'ın savı, bu çıkarımda nicelik, nitelik, bağıntı ve tarz olmak üzere dört grupta toplanabilen ilkelerin (maksimler) belirleyici rol oynadığıdır.

I offer two potential diagnoses of the behavioral norms governing post‐truth politics by comparing the view of language, communication, and truth‐telling put forward by David Lewis (extended by game theorists), and John Searle. My first goal is to specify the different ways in which Lewis, and game theorists more generally, in contrast to Searle (in the company of Paul Grice and Jurgen Habermas), go about explaining the normativity of truthfulness within a linguistic community. The main difference is that for (...) Lewis and game theorists, “truthful” signaling follows from an align- ment of interests, and deception follows from mixed motives leading to the calculation that sending false information is better for oneself. Following in the Enlightenment tradition, Searle argues that practical reasoning, which involves mastery of at least one language, requires that actors intend to communicate. This intention includes constraining the content of statements to uphold veracity conditions. After distinguishing between these two accounts, I will artic- ulate the implications for explaining, and even informing actions, constitutive of post‐truth politics. I argue that the strategic view of communication is suffi- cient neither to model everyday conversation nor to reflect a public sphere useful for democratic govern- ment. Both the pedagogy of strategic communication as cheap talk, and its concordance with new digital information technologies, challenge norms of truthful- ness that underlie modern institutions essential to an effective public sphere.

Özet: Bu yazı Paul Grice’ın 1967 yılında verdiği “Mantık ve Konuşma” başlıklı dersinin Türkçe çevirisinin okunmasına yardımcı olmayı amaçlamaktadır. Yazıda önce “Mantık ve Konuşma”nın arka planında yer alan dil felsefesi tartışmaları kısaca tanıtılmış sonrasında sezdirimler ve özellikleri, bağlam ve iletişimin ilkeleri gibi metinde geçen temel tartışmalar açıklanmıştır. En sonda ise “Mantık ve Konuşma”nın dil felsefesi ve dilbilimdeki etkilerinden kısaca söz edilmiştir. -/- Abstract: This paper aims at being helpful in reading the Turkish translation of Paul Grice’s 1967 lecture (...) titled “Logic and Conversation”. After introducing some relevant background discussions in the philosophy of language literature briefly, the paper explains the main discussions in “Logic and Conversation” such as implicatures and their features, context and principles of conversation. In the end, some influences of “Logic and Conversation” on philosophy of language and linguistics are briefly mentioned. (shrink)

Semanticists face substitution challenges even outside of contexts commonly recognized as opaque. Jennifer M. Saul has drawn attention to pairs of simple sentences - her term for sentences lacking a that-clause operator - of which the following are typical: -/- (1) Clark Kent went into the phone booth, and Superman came out. (1*) Clark Kent went into the phone booth, and Clark Kent came out. -/- (2) Superman is more successful with women than Clark Kent. (2*) Superman is more successful (...) with women than Superman. -/- She challenges us to explain why the upper and lower sentences in each pair differ, or at least appear to differ, in their truth-values and hence truth-conditions. This appearance of substitution failure is inherently puzzling. Moreover, it is taken by Saul to generate a dilemma for anyone hostile to direct reference accounts of that-clause constructions. Direct reference theorists regard the appearance of substitution failure in that-clause contexts as mere appearance, to be dealt with pragmatically rather than semantically. -/- Critics of such accounts need to say something about simple-sentence cases. If they choose to allow that intuitions of substitution failure can be over-ridden and explained away pragmatically in simple-sentence cases but not in that-clause cases, they lay themselves open to the charge of operating a double standard. But if they do not choose this option, they must offer a semantic explanation of apparent substitution failure in simple-sentence cases - no easy task, it turns out. Other respondents to Saul's challenge have sought to provide elaborate semantic treatments. In contrast, this paper proposes a far simpler pragmatic explanation of intuitions of substitution failure in simple sentences, an explanation that deploys no more resources than are to be found in Grice's 'Logic and Conversation'. Ironically, this proposal turns out to be incompatible with a direct reference perspective. So if it is, as I maintain, the most plausible treatment of simple-sentence cases available, Saul's initial thought gets turned around 180 degrees: the phenomenon she has drawn attention to ends up representing a challenge to supporters of direct reference theories.

Abstract The first part argues that being an image is an (at least) four part relation between the image itself (x2), properties of recipients (B), the object (x3), and properties of the object (M). Referring to Grice, Schiffer, and Meggle, a distinction is made between communicativity and non-communicativity (manipulativity) of x2 regarding to B, x3, and M. The second part substitutes sign and image by explicates that denote properties relevant for x2 being an image regarding to B, x3, and (...) M, making thus clear why images are signs. Intentional relations and causal relations are the basis of this explication (influenced by Posner) that is also meant to give an idea of those properties that are typical of pieces of fine arts and of some other cultural practices. Additionally, it helps in understanding the difference between typical images and more abstract symbols. -/- Im ersten Abschnitt werden Gründe dafür genannt, Bildsein als mindestens vierstellige Beziehung aufzufassen: als Beziehung zwischen dem Bild (x2), Rezipienteneigenschaften (B), dem Bildgegenstand (x3) und Eigenschaften (M) des Bildgegenstandes. Dabei wird – anknüpfend an Grice, Schiffer und Meggle – zwischen Kommunikativität und NichtKommunikativität (Manipulativität) von x2 bzgl. B, x3 und M unterschieden. Im zweiten Abschnitt wird die Rede von ›Zeichen‹ und von ›Bildsein‹ ersetzt durch Explikate, die Eigenschaften bezeichnen, welche relevant dafür sind, dass x2 ein Bild bzgl. B, x3 und M ist – derart, dass deutlich wird, inwiefern Bilder Zeichen sind. Basis dieser – von Posner angeregten – Explikationen sind intentionale Beziehungen und Bewirken. Aus den Begriffspräzisierungen ergeben sich Einsichten sowohl in Bezug auf Eigenschaften, die typisch für Werke Bildender Kunst und einige andere kulturelle Praktiken sind, als auch in Bezug auf eine Abgrenzung zentraler Vertreter der Kategorie ›Bild‹ von eher nur bildhaften Symbolen.

Özet: Bu yazıda nefret sözcüklerinin dilsel işlevi açıklanmaya çalışılacaktır. Bunun için öncelikle nefret sözcüklerinin kimi özelliklerini tartışıp sonrasında bu özelliklerin tümünün önereceğim sözcük sezdirimine dayalı nefret sözcükleri kuramı ile başarıyla açıklanabileceğini savunacağım. Buna göre nefret sözcükleri sözcük anlamı olarak bir insan grubuna işaret ederken, tipik kullanımlarında kimi olumsuz nitelikleri sözcük düzeyinde sezdirirler. Sözcük sezdirimi kavramı Grice'ın sezdirim kavramının bir tümcecikten daha küçük dilsel yapılara uyarlanmasıyla ortaya çıkar. Bu uyarlamanın olanaklı olduğunun gösterilmesi için Grice’ın tümce düzeyi için tasarladığı ilke (...) ve maksimlerin tümce altı düzeyde nasıl işlediğini açıklayacağım. Abstract: This paper aims at explaining the linguistic function of slurs. To this aim, I will first discuss certain features of slurs and then argue that these features can be successfully explained in my suggested phrasal implicature theory of slurs. In this view, slurs denote a group of people, and in their typical use they imply certain negative features at the phrasal level. Phrasal implicature is a notion which is developed by adapting Gricean notion of implicature to the linguistic units that are smaller than a clause. In order to show that this adaptation is possible, I will demonstrate how the Gricean principles and maxims work at the subsentential level. (shrink)

Syntax has to do with rules that constrain how words can combine to make acceptable sentences. Semantics (Frege and Russell) concerns the meaning of words and sentences, and pragmatics (Austin and Grice) has to do with the context bound use of meaning. We can hence distinguish between three competing principles of translation: S—translation preserves the syntax of an original text (ST) in the translation (TT); M—translation preserves the meaning of an ST in a TT; and P—translation preserves the pragmatics (...) of an ST in a TT. A prominent form of P is functionalism defended by linguists and translation theorists (J.R. Firth, Eugene Nida, Susan Bassnett and many others) and historically was defended by philosophers (Russell, Ogden and Richard) but abandoned by philosophers and criticized by Wittgenstein. If we adopt M, then a TT will always say exactly what the ST says, and hence all subsequent TTs, even alternative ones produced via M, will be consistent with each other. But if we adopt P, in contrast, we have no reason to believe that the TTs will say what the ST does, and moreover they can contradict each other. If such contradictory translations are produced on the basis of the totality of empirical evidence, it results in what Quine called the indeterminacy of translation. Yet, P is not easy to reject. In many cases, translation in accordance with M where the meaning to be preserved is linguistic results in TTs that are failures. In contrast to a language focused approach to semantics, I close by following a lead in the translation theory literature of identifying text-types (genres) as a tool for identifying translatable content in an ST. To individuate text-types I identify them with disciplines, as elucidated by the 2nd century Patañjali’s Yoga Sūtra. This allows for the definition of textual meaning as the discipline relative pragmatics of an ST and further for translation to proceed by way of M, while taking the intuitions that motivate P seriously. Translations that preserve textual meaning will not only have the same meaning as each other but will be pragmatically felicitous. (shrink)

Misconceived Consent: Miguel has stage IV lung cancer. He has nearly exhausted his treatment options when his oncologist, Dr. Llewellyn, tells him about an experimental vaccine trial that may boost his immune response to kill cancer cells. Dr. Llewellyn provides Miguel with a consent form that explains why the study is being conducted, what procedures he will undergo, what the various risks and benefits are, alternative sources of treatment, and so forth. She even sits down with him, carefully talks through (...) the most important points, and gives him time to ask questions. Though it is a Phase 1 study and the chance that he will benefit is very low, Miguel happily agrees to take part. A week later, after the first experimental injection, she asks him if he is worried about the risks. “Risks?” he asks. “I’m sure this is safe—you’re a doctor, after all!”. (shrink)

The thesis is a metatheoretical analysis of the concept of ‘speaker’s intention’ as it is used in traditional linguistic-philosophical and in cognitive pragmatics. The analysis centers around works of Austin, Searle, Grice, and Relevance Theory. The main aim is to argue for the following thesis: (T1) if pragmatics is targeting on how speaker’s intentions contribute to linguistic choices in communicative language use, then focusing solely on causally efficient mental states and analyzing them at the utterance level necessarily leads to (...) unsatisfactory consequences in theorizing. -/- The secondary aim of the dissertation is to argue that: (T2) the traditional account of intentionality is tenable only if we take utterances as data. Surely, there are causally efficient intentions which lead the speaker to formulate her utterances as part of conversational turns. But speakers also have intentions which shape the conversation itself (motives, goals, plans). However: (T3) if we take discourses or conversations as divergent sources of data (besides of utterances), we run into an explanatory gap that cannot be filled mechanically: the structured-proposionalist theory is simply insufficient to grasp discourse-level intentions. To argue for (T3), I analyse speaker’s intentions in a fictive conversation (The smuggler sketch from Monty Python’s Flying Circus) through the “prisms” of Austin’s speech act theory, Searle’s (at least) two theories of intentions, Grice’s M-intention, and the ostensive-inferential view on communication.

I argue for an account of grasping, or understanding that, on which we grasp via a higher‐order mental act of Husserlian fulfillment. Fulfillment is the act of matching up the objects of our phenomenally presentational experiences with those of our phenomenally representational thought. Grasping‐by‐fulfilling is importantly different from standard epistemic aims, in part because it is phenomenal rather than inferential. (I endorse Bourget's (2017) arguments to that effect.) I show that grasping‐by‐fulfilling cannot be a species of propositional knowledge or belief, (...) and that it is not essentially connected to justification. I motivate a revisionary epistemology on which achieving propositional knowledge and coming to grasp are dual epistemic aims. My account makes sense of a common occurrence—that we are often unmoved to act on our beliefs until we come to phenomenally experience them in some way. It also explains puzzling features of human inquiry. (shrink)

A consensus exists among contemporary philosophers of biology about the history of their field. According to the received view, mainstream philosophy of science in the 1930s, 40s, and 50s focused on physics and general epistemology, neglecting analyses of the 'special sciences', including biology. The subdiscipline of philosophy of biology emerged (and could only have emerged) after the decline of logical positivism in the 1960s and 70s. In this article, I present bibliometric data from four major philosophy of science journals (Erkenntnis, (...) Philosophy of Science, Synthese, and the British Journal for the Philosophy of Science), covering 1930-59, which challenge this view. (shrink)

I critically examine the semantic view of theories to reveal the following results. First, models in science are not the same as models in mathematics, as holders of the semantic view claim. Second, when several examples of the semantic approach are examined in detail no common thread is found between them, except their close attention to the details of model building in each particular science. These results lead me to propose a deflationary semantic view, which is simply that model construction (...) is an important component of theorizing in science. This deflationary view is consistent with a naturalized approach to the philosophy of science. (shrink)

Philosophers of science turned to historical case studies in part in response to Thomas Kuhn's insistence that such studies can transform the philosophy of science. In this issue Joseph Pitt argues that the power of case studies to instruct us about scientific methodology and epistemology depends on prior philosophical commitments, without which case studies are not philosophically useful. Here I reply to Pitt, demonstrating that case studies, properly deployed, illustrate styles of scientific work and modes of argumentation that are not (...) well handled by currently standard philosophical analyses. I illustrate these claims with exemplary findings from case studies dealing with exploratory experimentation and with interdisciplinary cooperation across sciences to yield multiple independent means of access to theoretical entities. The latter cases provide examples of ways that scientists support claims about theoretical entities that are not available in work performed within a single discipline. They also illustrate means of correcting systematic biases that stem from the commitments of each discipline taken separately. These findings illustrate the transformative power of case study methods, allow us to escape from the horns of Pitt's "dilemma of case studies," and vindicate some of the post-Kuhn uses to which case studies have been put.

David Chalmers' dancing qualia argument is intended to show that phenomenal experiences, or qualia, are organizational invariants. The dancing qualia argument is a reductio ad absurdum, attempting to demonstrate that holding an alternative position, such as the famous inverted spectrum argument, leads one to an implausible position about the relation between consciousness and cognition. In this paper, we argue that Chalmers' dancing qualia argument fails to establish the plausibility of qualia being organizational invariants. Even stronger, we will argue that the (...) gap in the argument cannot be closed. (shrink)

Artificial intelligence (AI) is an area of computer science that emphasizes the creation of intelligent machines or software that work and react like humans. Some of the activities computers with artificial intelligence are designed for include, Speech, recognition, Learning, Planning and Problem solving. Deep learning is a collection of algorithms used in machine learning, It is part of a broad family of methods used for machine learning that are based on learning representations of data. Deep learning is a technique used (...) to produce Pneumonia detection and classification models using x-ray imaging for rapid and easy detection and identification of pneumonia. In this thesis, we review ways and mechanisms to use deep learning techniques to produce a model for Pneumonia detection. The goal is find a good and effective way to detect pneumonia based on X-rays to help the chest doctor in decision-making easily and accuracy and speed. The model will be designed and implemented, including both Dataset of image and Pneumonia detection through the use of Deep learning algorithms based on neural networks. The test and evaluation will be applied to a range of chest x-ray images and the results will be presented in detail and discussed. This thesis uses deep learning to detect pneumonia and its classification. (shrink)

This contribution provides an assessment of the epistemological role of scientific models. The prevalent view that all scientific models are representations of the world is rejected. This view points to a unified way of resolving epistemic issues for scientific models. The emerging consensus in philosophy of science that models have many different epistemic roles in science is presented and defended.

Cognitive categories in the geographic realm appear to manifest certain special features as contrasted with categories for objects at surveyable scales. We have argued that these features reflect specific ontological characteristics of geographic objects. This paper presents hypotheses as to the nature of the features mentioned, reviews previous empirical work on geographic categories, and presents the results of pilot experiments that used English-speaking subjects to test our hypotheses. Our experiments show geographic categories to be similar to their non-geographic counterparts in (...) the ways in which they generate instances of different relative frequencies at different levels. Other tests, however, provide preliminary evidence for the existence of important differences in subjects’ categorizations of geographic and non-geographic objects, and suggest further experimental work especially with regard to the role in cognitive categorization of different types of object-boundaries at different scales.

Hubert Dreyfus has argued that cases of absorbed bodily coping show that there is no room for self-awareness in flow experiences of experts. In this paper, I argue against Dreyfus’ maxim of vanishing self-awareness by suggesting that awareness of agency is present in expert bodily action. First, I discuss the phenomenon of absorbed bodily coping by discussing flow experiences involved in expert bodily action: merging into the flow; immersion in the flow; emergence out of flow. I argue against the claim (...) that flow experience does not involve an awareness of agency for each of these features, while conceding that fluent agency does not involve self-awareness in the thetic sense. I challenge the assumption that the awareness of fluent agency must be understood in terms of a thetic awareness of agency. Instead, I develop an Anscombean account of the awareness of fluent agency in terms of the phenomenal character of knowing one’s aims. I respond to the challenge that if an Anscombean account of the awareness of agency is to succeed, then agents must be able to answer Anscombean questions. I consider the objection that awareness of agency is not a form of self-awareness by outlining an account of self-awareness as self-synthesis that is distinct from self-perception and self-ascription, but which makes room for self-awareness in expert bodily action.

I propose an approach to naturalized philosophy of science that takes the social nature of scientific practice seriously. I criticize several prominent naturalistic approaches for adopting "cognitive individualism", which limits the study of science to an examination of the internal psychological mechanisms of scientists. I argue that this limits the explanatory capacity of these approaches. I then propose a three-level model of the social nature of scientific practice, and use the model to defend the claim that scientific knowledge is socially (...) produced. (shrink)

The problem of evil is broadly considered to be one of the greatest intellectual threats to traditional brands of theism. And William Rowe’s 1979 formulation of the problem in “The Problem of Evil and Some Varieties of Atheism” is the most cited formulation in the contemporary philosophical literature. In this paper, we explore how the tools and resources of experimental philosophy might be brought to bear on Rowe’s seminal formulation, arguing that our empirical findings raise significant questions regarding the ultimate (...) success of Rowe’s argument. Such a result would be quite notable within philosophy of religion, since this is considered one of the most formidable arguments against theism. However, further testing is needed before any firm conclusions can be drawn. -/- In section 1, we elucidate Rowe’s formulation of the problem of evil and the intuitions that seem to underwrite it. In section 2, we explore how the tools and resources of experimental philosophy might be brought to bear on Rowe’s formulation, outlining our hypotheses and our methods for testing them before showcasing our results. In section 3, we discuss the philosophical import of our results–arguing that our results, when taken together, pose an initial challenge to Rowe’s seminal argument. (shrink)

Attempts have been made to prove God's non-existence. Often this takes the form of an appeal to the so-called Argument from Evil: if God were to exist, then he would not permit as much suffering in the world as there actually is. Hence the fact that there is so much suffering constitutes evidence for God's non-existence. In this essay I propose a variation which I shall call ‘The Argument from Non-belief’. Its basic idea is that if God were to exist, (...) then he would not permit as much non-belief in the world as there actually is. Hence the fact that there is so much non-belief constitutes evidence for God's non-existence. (shrink)

Abstract: Heart diseases are increasing daily at a rapid rate and it is alarming and vital to predict heart diseases early. The diagnosis of heart diseases is a challenging task i.e. it must be done accurately and proficiently. The aim of this study is to determine which patient is more likely to have heart disease based on a number of medical features. We organized a heart disease prediction model to identify whether the person is likely to be diagnosed with a (...) heart disease or not using the medical features of the person. We used many different algorithms of machine learning such as Gaussian Mixture, Nearest Centroid, MultinomialNB, Logistic RegressionCV, Linear SVC, Linear Discriminant Analysis, SGD Classifier, Extra Tree Classifier, Calibrated ClassifierCV, Quadratic Discriminant Analysis, GaussianNB, Random Forest Classifier, ComplementNB, MLP Classifier, BernoulliNB, Bagging Classifier, LGBM Classifier, Ada Boost Classifier, K Neighbors Classifier, Logistic Regression, Gradient Boosting Classifier, Decision Tree Classifier, and Deep Learning to predict and classify the patient with heart disease. A quite helpful approach was used to regulate how the model can be used to improve the accuracy of prediction of heart diseases in any person. The strength of the proposed model was very satisfying and was able to predict evidence of having a heart disease in a particular person by using Deep Learning and Random Forest Classifier which showed a good accuracy in comparison to the other used classifiers. The proposed heart disease prediction model will enhances medical care and reduces the cost. This study gives us significant knowledge that can help us predict the person with heart disease. The dataset was collected from Kaggle depository and the model is implemented using python. (shrink)

I suggest that the social justice issues raised by Internet regulation can be exposed and examined by using a methodology adapted from that described by John Rawls in 'A Theory of Justice'. Rawls' theory uses the hypothetical scenario of people deliberating about the justice of social institutions from the 'original position' as a method of removing bias in decision-making about justice. The original position imposes a 'veil of ignorance' that hides the particular circumstances of individuals from them so that they (...) will not be influenced by self-interest. I adapt Rawls' methodology by introducing an abstract description of information technology to those deliberating about justice from within the original position. This abstract description focuses on computing devices that users can use to access information and information networks that information devices use to communicate. The abstractness of this description prevents the particular characteristics of the Internet and the computing devices in use from influencing the decisions about the just use and regulation of information technology and networks. From this abstract position, the principles of justice that the participants accept for the rest of society will also apply to the computing devices people use to communicate, and to Internet regulation.

Philosophers of science often assume that logically equivalent theories are theoretically equivalent. I argue that two theses, anti-exceptionalism about logic (which says, roughly, that logic is not a priori, that it is revisable, and that it is not special or set apart from other human inquiry) and logical realism (which says, roughly, that differences in logic reflect genuine metaphysical differences in the world), make trouble for both this commitment and the closely related commitment to theories being closed under logical consequence. (...) I provide three arguments. The first two show that anti-exceptionalism about logic provides an epistemic challenge to both the closure and the equivalence claims; the third shows that logical realism provides a metaphysical challenge to both the closure and the equivalence claims. Along the way, I show that there are important methodological upshots for metaphysicians and philosophers of logic. In particular, there are lessons to be drawn about certain conceptions of naturalism as constraining the possibilities for metaphysics and the philosophy of logic. (shrink)

Organismal death is foundational to the evolution of life, and many biological concepts such as natural selection and life history strategy are so fashioned only because individuals are mortal. Organisms, irrespective of their organization, are composed of basic functional units—cells—and it is our understanding of cell death that lies at the heart of most general explanatory frameworks for organismal mortality. Cell death can be exogenous, arising from transmissible diseases, predation, or other misfortunes, but there are also endogenous forms of death (...) that are sometimes the result of adaptive evolution. These endogenous forms of death—often labeled programmed cell death, PCD—originated in the earliest cells and are maintained across the tree of life. Here, we consider two problematic issues related to PCD (and cell mortality generally). First, we trace the original discoveries of cell death from the nineteenth century and place current conceptions of PCD in their historical context. Revisions of our understanding of PCD demand a reassessment of its origin. Our second aim is thus to structure the proposed origin explanations of PCD into coherent arguments. In our analysis we argue for the evolutionary concept of PCD and the viral defense-immunity hypothesis for the origin of PCD. We suggest that this framework offers a plausible account of PCD early in the history of life, and also provides an epistemic basis for the future development of a general evolutionary account of mortality.

Information may be defined as the conceptual or communicable part of the content of mental acts. The content of mental acts includes sensory data as well as concepts, particular as well as general information. An information system is an external (non-mental) system designed to store such content. Information systems afford indirect transmission of content between people, some of whom may put information into the system and others who are among those who use the system. In order for communication to happen, (...) the conceptual systems of the originators and users of the information must be sufficiently similar. A formal conceptual framework that can provide the basis for exchange of information is termed an ontology. In its most fundamental form, ontology studies the most basic constituents of reality. Traditionally, ontology seeks to reflects structures that are independent of thought and cognition. The term ontology is used more broadly in artificial intelligence and software engineering, to refer to the conceptual basis for an information system. (shrink)

We present an abstract social aggregation theorem. Society, and each individual, has a preorder that may be interpreted as expressing values or beliefs. The preorders are allowed to violate both completeness and continuity, and the population is allowed to be infinite. The preorders are only assumed to be represented by functions with values in partially ordered vector spaces, and whose product has convex range. This includes all preorders that satisfy strong independence. Any Pareto indifferent social preorder is then shown to (...) be represented by a linear transformation of the representations of the individual preorders. Further Pareto conditions on the social preorder correspond to positivity conditions on the transformation. When all the Pareto conditions hold and the population is finite, the social preorder is represented by a sum of individual preorder representations. We provide two applications. The first yields an extremely general version of Harsanyi's social aggregation theorem. The second generalizes a classic result about linear opinion pooling. (shrink)

After a presentation of the problem of God's hiddenness, there is discussion of two arguments for God's nonexistence related to that problem. One is the Lack-of-evidence Argument (LEA), according to which there would have been good objective evidence of God's existence if he were to exist. The other is the Argument from Nonbelief (ANB), according to which there would not be as many nonbelievers as there actually are if God were to exist. Reasons are given for assessing ANB as a (...) stronger argument than LEA. (shrink)

Cross-species comparisons are benefited by compatible datasets; conclusions related to phylogenetic comparisons, questions on convergent and divergent evolution, or homologs versus analogs can only be made when the behaviors being measured are comparable. A direct comparison of the social function of physical contact across two disparate taxa is possible only if data collection and analyses methodologies are analogous. We identify and discuss the parameters, assumptions and measurement schemes applicable to multiple taxa and species that facilitate cross-species comparisons. To illustrate our (...) proposed guidelines for evaluating the role played by tactile contact in social behavior across disparate taxa, this paper presents data on mother-offspring relationships in the two species studied by the authors: chimpanzees (Pan troglodytes schweinfurthii) and dolphins (bottlenose and spotted, Tursiops truncatus and Stenella frontalis, respectively). Cross-species comparative studies allow for a more comprehensive assessment of the similarities and differences with respect to how animals traverse the relationships that form their social groups and societies.

In this paper, I argue that Kant's famous critique of the Ontological Argument largely begs the question against that argument, and is no better when supplemented by the modern quantificational analysis of "exists." In particular, I argue that the claim, common to Hume and Kant, that conceptual truths can never entail substantive existential claims is false,and thus no ground for rejecting the Ontological Argument.

Descartes argues that, apart from the existence of a veracious God, we can have no reason to believe that we possess reliable cognitive faculties, with the result that, if atheism is true, not even our seemingly most certain beliefs can count as knowledge for us. Since the atheist denies the existence of God, he or she will be precisely in this position. I argue that Descartes' argument is sound, and that atheism is therefore self-refuting.

In this paper, I defend traditional Platonic mathematical realism from its contemporary detractors, arguing that numbers, understood as abstract, non-physical objects of rational intuition, are indispensable for the act of counting.

Mango is an economically significant fruit crop cultivated in various tropical and subtropical regions around the world. However, the productivity and quality of mangoes can be severely impacted by a range of pests. This research paper introduces an innovative approach to identify mango pests using an expert system. The expert system integrates knowledge from entomology and plants to provide accurate identification of common mango pests. The paper outlines the development and implementation of the expert system using Clips shell, which utilizes (...) rule-based techniques to analyze symptoms associated with mango pests. By inputting observed symptoms, such as leaf spots, fruit damage, leaf mild and stem cankers the system can accurately identify the specific pest species affecting the mango tree. For each pest, the paper discusses their specific symptoms and Favorable conditions that affect the mango plant. By understanding the identification and symptoms of these pests, mango growers and agricultural professionals can implement appropriate pest management strategies to mitigate the economic losses caused by these insects.

A version of the Fine-tuning Argument (FTA) considered in a previous essay is replaced by an improved version, which is then refuted.Advocates of FTA must proclaim that there is no world ensemble, that a great many alternatives to the physical constants of our universe are physically possible and roughly equal in probability to them, and that alternate hypothetical worlds are all, or almost all, uninteresting in comparison to our universe. But no reason has been produced to believe any of these (...) claims, and so FTA, even in its improved version, can still be dismissed as unsupported, doubtful, and weak. (shrink)

In this paper, I discuss the Categorical Imperative as a basis for an Ethics of Belief and its application to Kant's own project in his theoretical philosophy.

In his Beweisgrund (1762), Kant presents a sketch of "the only possible basis" for a proof of God's existence. In this essay, I attempt to present that proof as a valid and sound argument for the existence of God.

In this paper, I present the case for an objective, as opposed to subjective, conception of happiness along familiar, classical lines.

In this paper I argue that there is no problem of Divine Hiddenness for Christians and offer an alternate explanation for the widespread claim that God's existence is hidden based on the Christian doctrine of Original Sin.

Hume was correct in his critique of causation as understood by the New Science, a critique deadly to both causal and scientific realism. Getting beyond Hume's critique of causation requires that we call into question the New Science's understanding of causation and replace it with a Neo-Aristotelian account of causal processes. In this paper, I try to point the way to such an account.
