This paper addresses the issues related to designing and estimating the strength of solid-alloy elements in the deforming broaches of significant diameter (exceeding 150 mm) for the developed process of discrete broaching. The tool limit condition was assessed based on two strength criteria: the specific potential energy of shape change and the maximum tangent stresses. Numerical modeling using the finite element method has made it possible to derive the distribution of equivalent stresses in the tool elements and the (...) contact stresses at the surface of the contact between a solid-alloy insert and the body, which enabled the analysis of tool strength under loading. The simulation was performed under a single normal load, which ensured the versatility of the calculation for any contact pressure values. We have derived formulae to calculate the acceptable contact pressure depending on unit load. The effect of the insert protrusion height over the body on the strength of tool elements has been established. We have derived engineering dependences that determine the required magnitude of insert protrusion over the body depending on the ultimate load. An example of calculating the strength of a prefabricated deforming element in the machining of a sleeve made from gray modified cast iron of hardness HB230 has been considered. Our calculations have shown that the deforming element designed for the new technological process corresponds to the conditions of strength, provided the ratio h1/h=0.15 is maintained (where h1 is the insert height above the body, h is the insert height). The results obtained could be used in engineering calculations when designing the prefabricated tool for discrete deformation, as well as to assess the strength of prefabricated tools, such as cutters, core drills, reamers, when refining external loads.

Purpose. To determine the potential of deforming broaching for the improvement of efficiency of cutter chisels in the mining industry. Methodology. The study of the application of the technological process of deforming broaching was carried out based on the experimental research into conditions of assembly of press couplings corresponding to cutting rock-destroying tools, the working surface of which is reinforced with solid-alloy inserts. Findings. Based on the conducted research, a new process of assembling the crowns of cutter chisels (...) with the use of deforming broaching was developed. Originality. It was determined that the range of angles of inclination of generatrix of the working cone of the deforming element and the roll-treading lip of the insert, which are necessary for efficient machining and pressing in crowns of cutters, is 4–16°. It was proven that the “solid alloy-steel” press couplings for cutter chisels will have the maximum bearing capacity at total tension a/d0 ≤ 3 %. It was found that it is necessary to foresee the following distribution of tensions: to perform 2 % of deformation by preliminary deforming broaching, and 1 % ‒ by pressing in an insert Practical value. The use of deforming broaching makes it possible to increase the strength of fastening the inserts of cutter chisels by 2 times, to reduce specific consumption of the tool by 4.4 times, and to increase the average drilling rate by 4 times.

Human actions and decisions are most of the times not only grounded on emotional reactions, they are irrationally debasing. While such emotions and heuristics were perhaps suitable for dealing with life in the Stone Age, they are woefully inadequate in the Silicon Age. The substitution of traditional news agencies and communication platforms in Nigeria with social media networks has not only increased human capacities, it has aided the common good and further eased communication and increased the human knowledge base. For (...) instance, the Silicon Valley in the state of California in the United State of America has proved the extent to which human ingenuity can be exerted in beneficial ways. Here in, the top of the multibillion-dollar communication companies like Apple, eBay, Cisco, Lockheed, Hewlett Packard (HP), Google, Netflix, Facebook, Oracle, Tesla, etc. whose yearly budgets far exceed the entire yearly budget of Nigeria, has proved that, ICT remains the building blocks of contemporary communities. The state of California for instance prides herself as the 6th largest economy of the world after France and Brazil. This romantic picture of ICT is but only one chapter of the ICT divide. In today’s world, the scale and speed of the highly partisan news and falsehoods that circulate in the human environment is deafening. In politics and governance for instance, the populist have exploited the ICT effectively and without restraints, to access power and authority. Today, we are in the era of post-truth, an era in which objective facts are less influential in shaping public opinion than appeals to emotion and personal belief. An era that harbours corruption of intellectual integrity and damage to the whole fabric of democracy. The battle to protect information integrity and expose fake news becomes sine qua non. We shall in this paper explore the dark side of the age of information, a side that has been exploited by the media mavens, political hacks, and ideological propagandists who promote lies, illusion, confusion, and other forms of demented or manipulated imagination. In doing this, we shall proceed as follows: i. Historicize the concept of ‘fake news’ here referred to as post-truth. ii. Interrogate the concept of ‘information’ and its goal in human affairs iii. Evaluate the nexus between ‘truth’ values in ‘information’, ‘Misinformation’ and ‘dis-information’ iv. Situate the role of Philosophy in the era of post-truth. (shrink)

Man, in the Heraclitean principle of change, is an embodiment of continuity and discontinuity. To what end man’s being transcends to, is an interrogative of important discourse in this paper. Does Man flux from life to death; in nothingness, and from death, in nothingness, to life in somethingness? What does it mean to be human, to die and to experience change and human transcendence? The frequent nature of death, the death of loved ones, colleagues and friends elicit lamentations and sorrows, (...) but more importantly, it expresses human incapacity, fear of the unknown, lack of knowledge of death, and of what it means to die. Such attitude or confusion, may have informed the interrogative of Job (14:14): If man dies shall he live again? It also agitates the triad; if a man lives to die, does he die to live? If God is life, is God death also? If life is a means to an end, is death the end? (Adadevo, 2008; 38). These interrogatives exemplify the character and paradox of human existence; the more the knowledge of man about man, the more Man understands that he knows little about his being. It is argued here that, as a being that encapsulate change, discontinuity and continuity, man’s dissolution in death is not an external and public fact that creates a sense of loss and sadness to humanity, but an internal possibility of his being. It is the fulfillment of the Man project of self-liberation, self-transcendence, and a process of surpassing Man’s existential condition. We shall argue further that, in death, man ceases to be the impersonal social being among beings and has freed himself from the servitude of the anonymous “they” and thereby opened himself to his own most potentiality for being. In birth, there is the change of non-being to being, of nothingness to somethingness (somaticity), then to pure being after death; to a spiritual reality. A conclusion is argued that, in death, Man further becomes the most vitalizing fact of life and the cardinal indicator of authentic selfhood. (shrink)

In the Principles of Philosophy, Descartes attempts to explicate the well-known phenomena of varying bodily size through an appeal to the concept of "solidity," a notion that roughly corresponds to our present-day concept of density. Descartes' interest in these issues can be partially traced to the need to define clearly the role of matter in his natural laws, a problem particularly acute for the application of his conservation principle. Specifically, since Descartes insists that a body's "quantity of motion," defined as (...) the product of its "size" and speed, is conserved in all material interactions, it is imperative that he explain how solidity influences the magnitude of this force. As a means of resolving this problem, Descartes postulated an idealized condition of "perfect solidity" which correlates a body's "agitation" force (a forerunner of Newton's concept of non-accelerating, or "inertial" motion) with the interplay of its volume, surface area, and composition of minute particles. This essay explores this often misunderstood aspect of Descartes' physics, as well as the special function of idealized conditions in his collision rules. Contrary to those commentators who regard "perfect solidity" as a stipulation on bodily impact, this notion, it will be argued, is primarily concerned with the internal composition of macroscopic bodies, and only indirectly with their collision characteristics. Along the way, many of Descartes' hypotheses will be shown to display a level of sophistication and intricacy that, despite their essential incompatibility, belie several of the common misconceptions of Cartesian science.

Ezra Pound got many things wrong. He was a poor judge of character and a supporter of causes and individuals that have done and continue to do much harm to people around the world. This book addresses the matters (literary and philosophical) that Pound got right, while still pointing out the flaws; it highlights the impact such evidence may yield for the student of art. -/- The result of my research in the pages that follow may be described as a (...) study in aesthetic affinities between Ezra Pound’s thought and the guiding notions found in the Confucian lore. The question it attempts to exemplify is that long-standing one about the nature of knowledge. -/- The analysis that follows seeks to provide a variety of perspectives (both in terms of disciplines and interpretations) about how Pound created with his writings a metaphor of knowledge to understand, assimilate, and put to use his discovery of the East as represented by the Confucian mind.

Traditional geometry concerns itself with planimetric and stereometric considerations, which are at the root of the division between plane and solid geometry. To raise the issue of the relation between these two areas brings with it a host of different problems that pertain to mathematical practice, epistemology, semantics, ontology, methodology, and logic. In addition, issues of psychology and pedagogy are also important here. To our knowledge there is no single contribution that studies in detail even one of the aforementioned (...) areas. (shrink)

We explore the ethics of using motivational interviewing, an evidence-based, client-centred and directional counselling method, in conversations with next of kin about deceased solid organ donation. After briefly introducing MI and providing some context around organ transplantation and next of kin consent, we describe how MI might be implemented in this setting, with the hypothesis that MI has the potential to bring about a modest yet significant increase in next of kin consent rates. We subsequently consider the objection that (...) using MI in this context would be manipulative. Although we cannot guarantee that MI would never be used in a problematically manipulative fashion, we conclude that its use would, nevertheless, be permissible as a potential means to increase next of kin consent to deceased solid organ donation. We propose that MI be trialled in consent situations with next of kin in nations where there is widespread public support for organ donation. (shrink)

Both biodegradable and non-biodegradable solid wastes are found in religious or worship places. Biodegradable waste consists of fruits, flowers, leaves, prepared food items, plantations, sweets and non-biodegradable waste consists of plastic covers, plastic plates, plastic cups, metal pieces, flags and so on. These were found during festivals, functions, yatras, urus, massive gatherings, and weddings in religious places. Large gatherings led to huge dumping of solid wastes in and around the religious places. The vendors and street hawkers after selling (...) their goods used to dump the leftover wastes near these places during the pre-pandemic period. During the pandemic outbreak from April 2020 to August 2020, the religious places were shut to the public leading to minimal or zero solid waste production. During lockdown relaxation from September 2020, these places were sanitized; people were restricted with minimal gatherings and instructed to follow COVID appropriate behaviour. Similarly during the second wave lockdown from May 2021 to August 2021, people were not allowed to visit these places which led to the reduction of solid waste production in religious places leading to reduction of air, water and soil pollution.

It is difficult to express integral consciousness using ordinary language because of the inherent tendency of language to separate and distinguish. Jean Gebser, in The Ever-Present Origin, suggested concepts such as transparency and diaphaneity as ways to access integral consciousness, and the Gnostic text The Thunder, Perfect Mind (TPM) is written from the perspective of a being with integral consciousness. I use Jean Gebser’s concepts of transparency and diaphaneity to explicate TPM, an enigmatic, paradoxical poem in the Nag Hammadi Library. (...) Because TPM is written from the perspective of an integral being, one who is All-of-It (i.e., paradoxical completeness rather than a consistent but incomplete persona), the poem calls the reader to embody such a perspective of being All-of-It, thereby enabling one to get beyond the limitations of either/or languaging and thinking by apperceiving the transparency of experience in space and through time.

The main aim of this essay is to show that, for Stevens, the concept of reality is very fluctuating. The essay begins with addressing the relationship between poetry and philosophy. I argue, contra Critchley, that Stevens’ poetic work can elucidate, or at least help us to understand better, the ideas of philosophers that are usually considered obscure. The main “obscure” philosophical work introduced in and discussed throughout the essay is Schelling’s System of Transcendental Idealism. Both a (shellingian) philosopher and a (...) (stevensian) poet search for reality. In order to understand Stevens’ poetry better, I distingush several concepts of reality: initial reality (the external world of the common sense), imagined reality (a fiction, a product of one’s mind), final reality (the object of a philosopher’s and a poet’s search) and total reality (the sum of all realities, Being). These determinations are fixed by reason (in the present essay), whereas in Stevens’ poetic works, they are made fluid by the imagination. This fluidity leads the concept of reality from its initial stage through the imagined stage to its final stage. Throughout this process, imagined reality must be distinguished from both a mere fancy and its products. Final reality is, however, nothing transcendent. It is rather a general transpersonal order of reality created by poetry/the imagination. The main peculiarity of final reality is that it is a dynamic order. It is provisional at each moment. Stevens (and Schelling too) characterizes this order as that of a work of art which is a finite object, but has an infinite meaning. Stevens calls this order “the central poem” or the “endlessly elaborating poem”. If ultimate reality is a poem created by the imagination, one may ask who is the imagining subject. I argue that this agent is best to be thought as total reality, that is, as Being. Stevens, however, maintains that if there were such an agency, it would be an inhuman agency, “an inhuman meditation”. The essay concludes, in a Derridian manner, with the claim that this agency cannot have any name; it is the “unnamed creator of an unknown sphere, / Unknown as yet, unknowable, / Uncertain certainty” (OP: 127). It is best thought as an X, as an unknown variable. Being has no name. (shrink)

The cases that Doris chronicles of confabulation are similar to perceptual illusions in that, while they show the interstices of our perceptual or cognitive system, they fail to establish that our everyday perception or cognition is not for the most part correct. Doris's account in general lacks the resources to make synchronic assessments of responsibility, partially because it fails to make use of knowledge now available to us about what is happening in the brains of agents.

This article was motivated by the avalanche of finance spent annually on addressing the harm caused by corrosion on household wares and buildings, industrial machines and facilities, hospital equipment and many other establishment of man in the universe. Corrosion is a universal phenomenon referred to as the deterioration of metallic material. Metal alloys like stainless steel and aluminium are extensively used in household utensils for their durability, affordability and corrosion resistance. However, these materials can leach heavy metals such as chromium, (...) nickel, iron, and aluminium into food, posing serious health challenges. Stainless steel, despite its corrosion resistance, releases harmful metals when exposed to acidic foods, while aluminium utensils corrode and release harmful elements under certain conditions too. Hence, this article was aimed at examining the historical background of corrosion, the causes of corrosion in household wares and utensils, its impact especially on human health and economy, and the potential remedies. The findings indicated that acidic foods and prolonged storage increase metal leaching. Health concerns included increased risks of anemia, dementia, and osteomalacia due to excessive metal accumulation in the body. Mitigation strategies included using anodized aluminium, minimizing storage time of acidic foods in metal containers, and increasing public awareness about the potential health risks. Proper maintenance and selection of utensils could significantly reduce the hazards associated with metal leaching. (shrink)

Disintegration is the most important step for drug bioavailability because after, the disintegration process, the ingredients of solid dosage forms dissolve and become bioavailable. Generally, the tablets and capsules should be taken with a glass of water otherwise the manufacturer gives instructions to use the proper beverage. Several drugs are taken with different forms of beverages to ensure easy swallowing of the tablet, masking the bad taste of the drug and overcoming the drug aftertaste, these beverages can influence the (...) disintegration of the solid dosage form. The most common cold beverages consumed by the Libyan population are juice, milk, and Coca-Cola. These beverages are consumed without awareness of the possible effect of these beverages on drugs, especially over-the-counter drugs such as analgesic, antipyretic, and anti-inflammatory drugs that are taken without a prescription. This study aimed to evaluate the influence of three beverages, namely: orange juice, milk, and Coca-Cola on the disintegration time of four over-the-counter-drugs: Panadol, Congestal, Brufen, and Reality Extra using disintegration test of drugs in 0.1 N HCL and in hybrid medium prepared by combination of 150 ml 0.1 N HCL and 550 ml of beverage to simulate in vivo condition. The findings show that the orange juice significantly increases the disintegration time of all the investigated drugs. Coca-Cola significantly increases the disintegration time of Reality Extra, and slightly increases the disintegration time of Brufen, Congestal, and Panadol and the full-fat milk significantly increases the disintegration time of Reality Extra and Panadol while slightly increasing the disintegration time for Brufen and Congestal. It is concluded that commonly used beverages affect the disintegration time of the examined over-the-counter drugs. Patients should be advised to take these medications without beverages which may delay the disintegration and the onset of action of the drug. (shrink)

This paper focuses on the question of filtration through the perspective of “too much information”. It concerns Western society within the context of new media and digital culture. The main aim of this paper is to apply a philosophical reading on the video game concept of Selection for Societal Sanity within the problematics of cultural filtration, control of behaviors and desire, and a problematization of trans-individuation that the selected narrative conveys. The idea of Selection for Societal Sanity, which derives from (...) the first postmodern video game Metal Gear Solid 2: Sons of Liberty (2001), is applied into a philosophical framework based on select concepts from Bernard Stiegler’s writing and incorporating them with current events such as post-truth or fake news in order to explore the role of techne and filtration within social organizations and individual psyches. Alternate forms of behavior, which contest cultural paradigms, are re-problematized as tension between calculability and incalculability, or market value versus social bonding. (shrink)

This largely expository lecture deals with aspects of traditional solid geometry suitable for applications in logic courses. Polygons are plane or two-dimensional; the simplest are triangles. Polyhedra [or polyhedrons] are solid or three-dimensional; the simplest are tetrahedra [or triangular pyramids, made of four triangles]. -/- A regular polygon has equal sides and equal angles. A polyhedron having congruent faces and congruent [polyhedral] angles is not called regular, as some might expect; rather they are said to be subregular—a word (...) coined for this lecture. To repeat, a subregular polyhedron has congruent faces and congruent [polyhedral] angles. A subregular polyhedron whose faces are all regular polygons is regular—using standard terminology. -/- Geometers before Euclid showed that there are “essentially” only five regular polyhedra: every regular polyhedron is a tetrahedron (4 faces), a hexahedron or cube (6 faces), an octahedron (8 faces), a dodecahedron (12 faces), or an icosahedron (20 faces). -/- The first question is whether there are subregular polyhedra that are not regular. For example, are there tetrahedra having congruent angles and congruent triangular faces but whose faces are not equilateral triangles? -/- Another question is the classification of subregular polyhedra if they exist. For example, considering the fact that the regular tetrahedra all have equilateral triangles as faces, we ask which triangles other than equilaterals are faces of subregular tetrahedra. Similarly, considering the fact that the regular hexahedra all have squares as faces, we ask which quadrangles other than squares are faces of subregular hexahedra. -/- After introductory remarks that include historical and philosophical points, we concentrate on tetrahedra. A triangle that is congruent to each of the four faces of a tetrahedron is called a generator of the tetrahedron. The main result proved is that every acute triangle is a generator of a subregular tetrahedron. The proof includes an algorithm –implementable with scissors and paper –that constructs from any given acute triangle a subregular tetrahedron whose faces are congruent to the given triangle. -/- Algorithm: Given any acute triangle. Construct a similar triangle whose sides are double the sides of the given triangle. Draw the three lines connecting the three midpoints of the sides (making four triangles congruent to the given triangle—a central triangle surrounded by three peripheral triangles). Make three “hinges” along the lines connecting the midpoints. “Fold” the peripheral triangles together (into a tetrahedron).

A solid foundation of modal logic requires a clear conception of the notion of modality. Modern modal logic treats modality as a propositional operator. I shall present an alternative according to which modality applies primarily to illocutionary force, that is, to the force, or mood, of a speech act. By a first step of internalization, modality applied at this level is pushed to the level of speech-act content. By a second step of internalization, we reach a propositional operator validating (...) the modal logic S4. After a brief discussion of problematic modality and possibility, the article concludes with an extension of the account that identifies modality with illocutionary force. Throughout, close attention is paid to the intended interpretation of the formalism. All of the rules stipulated will be justified on the basis of this interpretation. (shrink)

I have both a smaller and a larger aim. The smaller aim is polemical. Kit Fine believes that a material thing—a Romanesque statue, for example, or an open door—can be distinguished from its constituent matter—a piece of alloy, say, or a hunk of plastic—without recourse to modal or temporal considerations. The statue is Romanesque; the piece of alloy is not Romanesque. The door is open; the hunk of plastic is not open. I argue that these considerations, when combined (...) with a proper understanding of how the use of ‘not’ is functioning, entail that the statue is the piece of alloy, and that the door is the hunk of plastic. Far from challenging the doctrine that a material thing is its matter, Fine’s observations confirm the view. My larger aim is methodological. I will show that natural language semantics can guide inquiry in certain areas of metaphysics by helping us to advance lingering debates. (shrink)

Background: While the solid organ transplant evaluation process is designed to function equitably, discriminatory practices remain, resulting in disparities in access for persons with disabilities. Physical function and frailty status are often-cited factors in establishing transplant, despite limited consensus on their assessment and impact. Objective: The purpose of this study was to describe how transplant healthcare professionals conceptualize the relationship between physical disability and transplant candidacy. Methods: A convenience sample of multidisciplinary transplant was solicited to respond to an electronic (...) survey between February and March 2024. Results: Of the 126 professionals contacted, 43 participants responded, yielding a response rate of 34 %. The majority of participants (88 %) held contradictory views of physical disability as it relates to transplant candidacy (p = 0.049). Men were more likely to endorse awareness of bias when evaluating transplant candidates (p = 0.008). Professional discipline was significantly associated with perception of transplant process fairness, impact of bias, and interpretation of quality of life. Iterative thematic analysis revealed a propensity to conflate frailty with physical disability. Conclusions: Multidisciplinary transplant professionals rarely endorsed overtly ableist sentiments. However, responses highlighted inconsistent, unclear, and at times contradictory conceptions of physical function and physical disability, which may contribute to disparate access to solid organ transplant for individuals with physical disability.

Could it be right to convict and punish defendants using only statistical evidence? In this paper, I argue that it is not and explain why it would be wrong. This is difficult to do because there is a powerful argument for thinking that we should convict and punish defendants using statistical evidence. It looks as if the relevant cases are cases of decision under risk and it seems we know what we should do in such cases (i.e., maximize expected value). (...) Given some standard assumptions about the values at stake, the case for convicting and punishing using statistical evidence seems solid. In trying to show where this argument goes wrong, I shall argue (against Lockeans, reliabilists, and others) that beliefs supported only by statistical evidence are epistemically defective and (against Enoch, Fisher, and Spectre) that these epistemic considerations should matter to the law. To solve the puzzle about the role of statistical evidence in the law, we need to revise some commonly held assumptions about epistemic value and defend the relevance of epistemology to this practical question.

Concerns have been raised by both researchers and authorities regarding conspiracy theorists rejecting experts. To address the validity of these concerns, we need to delve into two key inquiries regarding who qualifies as an expert on conspiracy theories, and what constitutes an epistemically rational response (from a conspiracy theorist) when faced with expert testimony. The first inquiry presents a challenge when considering a reputationalist versus a realist account of experts. On the reputationalist account rejecting experts may be viewed as little (...) more than rejecting those whom society has collectively deemed as experts. Alternatively, adopting a realist account raises the challenge of determining who the genuine experts are. I argue that the realist account is the more compelling option for pursuing the first question. Moreover, I explore two prevalent accounts from existing literature that prescribe how epistemic agents should respond to expert testimony: the Preemptive View and the Community View. Through an examination using the simulation program Laputa, I demonstrate that both accounts are insufficient. Consequently, I argue that without a clear identification of experts in the broader context of conspiracy theories, the initial concern lacks a solid foundation, and the sense of urgency may be unwarranted.

Many of Søren Kierkegaard's most controversial and influential ideas are more relevant than ever to contemporary debates on ethics, philosophy of religion and selfhood. Kierkegaard develops an original argument according to which wholeheartedness requires both moral and religious commitment. In this book, Roe Fremstedal provides a compelling reconstruction of how Kierkegaard develops wholeheartedness in the context of his views on moral psychology, meta-ethics and the ethics of religious belief. He shows that Kierkegaard's influential account of despair, selfhood, ethics and religion (...) belongs to a larger intellectual context in which German philosophers such as Kant and Fichte play crucial roles. Moreover, Fremstedal makes a solid case for the controversial claim that religion supports ethics, instead of contradicting it. His book offers a novel and comprehensive reading of Kierkegaard, drawing on important sources that are little known. (shrink)

Proponents of epistocracy worry that high levels of voter ignorance can harm democracies. To combat such ignorance, they recommend allocating comparatively more political power to more politically knowledgeable citizens. In response, some recent critics of epistocracy contend that epistocratic institutions risk causing even more harm, since much evidence from political psychology indicates that more politically knowledgeable citizens are typically more biased, less open-minded, and more prone to motivated reasoning about political matters than their less knowledgeable counterparts. If so, perhaps epistocratic (...) institutions will perform worse epistemically than corresponding democratic institutions. Call this 'the problem of epistocratic irrationality'. This paper argues that the problem of epistocratic irrationality can be overcome. First, I argue that critics of epistocracy have overlooked several complications regarding the psychological data they claim shows that more knowledgeable citizens are less politically rational. Second, I argue that appropriately designed epistocratic institutions could overcome the problem of epistocratic irrationality even if such critics have interpreted the data correctly. I first explore whether refined selection mechanisms could allow epistocrats to avoid empowering less rational citizens, before assessing the prospects of implementing only those epistocratic institutions with a solid track record of reliable performance.

In the Introduction to the Treatise Hume very enthusiastically announces his project to provide a secure and solid foundation for the sciences by grounding them on his science of man. And Hume indicates in the Abstract that he carries out this project in the Treatise. But most interpreters do not believe that Hume's project comes to fruition. In this paper, I offer a general reading of what I call Hume's ‘foundational project’ in the Treatise, but I focus especially on (...) Book 1. I argue that in Book 1 much of Hume's logic is put in the service of the other sciences, in particular, mathematics and natural philosophy. I concentrate on Hume's negative thesis that many of the ideas central to the sciences are ideas that we cannot form. For Hume, this negative thesis has implications for the sciences, as many of the texts I discuss make evident. I consider and criticize different proposals for understanding these implications: the Criterion of Meaning and the ‘Inconceivability Principle’. I introduce what I call Hume's ‘No Reason to Believe’ Principle, which I argue captures more adequately the link Hume envisions between his logic, in particular his examination of ideas, and the other sciences.

This paper argues for the reasonableness of an inclusive conception of default reasoning. The inclusive conception allows untriggered default rules to influence beliefs: Since a default “from φ, infer ψ” is a defeasible inference rule, it by default warrants a belief in the material implication φ → ψ, even if φ is not believed. Such inferences are not allowed in standard default logic of the Reiter tradition, but are reasonable by analogy to the Deduction Theorem for classical logic. Our main (...) contribution is a formal framework for inclusive default reasoning. The framework has a solid philosophical foundation, it draws conclusions non-trivially different from non-inclusive frameworks, and it exhibits a host of benchmark properties deemed desirable in the literature—e.g., that extensions always exist and are consistent.

Since childhood, we ask ourselves and others the question “What is nature?” The correct and true answer is given to us by materialists, dialectical materialists. Nature is an objective reality that exists outside our consciousness and independently of our consciousness. Nature is everything that surrounds us, and ourselves. Everything that surrounds us and we ourselves belong to and exist in nature. Nature is everything. There is nothing and no one in the world that would not belong to nature. The concept, (...) category “nature” is the broadest concept. There is no more comprehensive concept. All this is wonderful, all this is true. But I want to specifically imagine all this and grasp it with my mind's eye. “Nature exists absolutely, without relation to anything or anyone” - this is the first concrete fact and the first concrete truth, with which, perhaps, the scientific knowledge of nature begins. The author of this article has a solid starting position, a large reserve. These are his results of scientific research within the framework of the scientific project “Theory of Nature” (TN). In 2021, the book of the same name? “Theory of Nature”, was published. TN is a scientific and dialectical-materialistic Revolution in physics and cosmology (cosmogony). Within the framework of this article, from the position of the only true and scientific philosophy of dialectical materialism and based on the revolutionary “Theory of Nature”, the fundamental question, the problem “What is NATURE” is solved? As it seems to the author, this is perhaps the limit of our knowledge of nature. (shrink)

Awareness is a two-place determinable relation some determinates of which are seeing, hearing, etc. Abstract objects are items such as universals and functions, which contrast with concrete objects such as solids and liquids. It is uncontroversial that we are sometimes aware of concrete objects. In this paper I explore the more controversial topic of awareness of abstract objects. I distinguish two questions. First, the Existence Question: are there any experiences that make their subjects aware of abstract objects? Second, the Grounding (...) Question: if an experience makes its subject aware of an abstract object, in virtue of what does it do so? I defend the view that intuitions, specifically mathematical intuitions, sometimes make their subjects aware of abstract objects. In defending this view, I develop an account of the ground of intuitive awareness. (shrink)

Physical boundaries and the earliest topologists. Topology has a relatively short history; but its 19th century roots are embedded in philosophical problems about the nature of extended substances and their boundaries which go back to Zeno and Aristotle. Although it seems that there have always been philosophers interested in these matters, questions about the boundaries of three-dimensional objects were closest to center stage during the later medieval and modern periods. Are the boundaries of an object actually existing, less-than-three-dimensional parts of (...) the object—that is, are solids bounded by two-dimensional surfaces, surfaces by one-dimensional “edges” or “physical lines”, edges by dimensionless “simples”? If not, how does a perfectly spherical object manage to touch a perfectly flat object—what part of the sphere is in immediate contact with the plane, if the sphere has no unextended parts? But if such parts be admitted, are we not then saddled with “actual infinities” of simples, lines, and surfaces spread throughout each continuous object—the boundaries of all the object’s internal parts? Does it help to say that these internal boundaries exist only “potentially”? (shrink)

McGrew & McGrew make a solid statistical case for the historicity of the resurrection. This article fills two lacunae in the argument given there, and repairs a conceptual error (making the first lacuna irrelevant in the process).

Category-based induction is an inferential mechanism that uses knowledge of conceptual relations in order to estimate how likely is for a property to be projected from one category to another. During the last decades, psychologists have identified several features of this mechanism, and they have proposed different formal models of it. In this article; we propose a new mathematical model for category-based induction based on distances on conceptual spaces. We show how this model can predict most of the properties of (...) this kind of reasoning while providing a solid theoretical foundation for it. We also show that it subsumes some of the previous models proposed in the literature and that it generates new predictions. (shrink)

Abstract: The paper presented is a work started in summer 2014 for improving surfaces of turned holes. The work was confined to two materials; aluminum alloy and brass alloy. The internal machined surfaces were burnished by ball burnishing tools. Experimental work was carried out on a lathe machine to establish the effect of the internal ball burnishing parameters; namely, burnishing feed rate, speed, force and number of tool passes on the Surface roughness and surface hardness. The operation was (...) carried out at load pushing speed 24 m/min through the hole. Turned Al-Br specimens were divided into groups, the parameters were changed with each group. The optimum values of surface roughness and surface hardness were obtained where the surface roughness improved from 3.14 µm to 0.14 µm for Al µm and from 2.25 to 0.16 for brass and the surface hardness improved from116 HV to 184 HV for Al and from 182 to 244 HV for brass.

Our senses provide us with information about the world, but what exactly do they tell us? I argue that in order to optimally respond to sensory stimulations, an agent’s doxastic space may have an extra, “imaginary” dimension of possibility; perceptual experiences confer certainty on propositions in this dimension. To some extent, the resulting picture vindicates the old-fashioned empiricist idea that all empirical knowledge is based on a solid foundation of sense-datum propositions, but it avoids most of the problems traditionally (...) associated with that idea. The proposal might also explain why experiences appear to have a non-physical phenomenal character, even if the world is entirely physical. (shrink)

In the semantic debate about perspectival expressions – predicates of taste, aesthetic and moral terms, epistemic modals, etc. – intuitions about armchair scenarios (e.g., disagreement, retraction) have played a crucial role. More recently, various experimental studies have been conducted, both in relation to disagreement (e.g., Cova, 2012; Foushee and Srinivasan, 2017; Solt, 2018) and retraction (e.g., Knobe and Yalcin, 2014; Khoo, 2018; Beddor and Egan, 2018; Dinges and Zakkou, 2020; Kneer 2021; 2022; Almagro, Bordonaba Plou and Villanueva, 2023; Marques, 2024), (...) with the aim of establishing a more solid foundation for semantic theorizing. Both these types of data have been used to argue for or against certain views (e.g., contextualism, relativism). In this paper, I discern a common thread in the use of these data and argue for two claims: i) which perspective is adopted by those judging the armchair scenarios put forward and by the participants in experimental studies crucially matters for the viability of the intended results; ii) failure to properly attend to this puts recent experimental work at risk. Finally, I consider the case of cross-linguistic disagreement and retraction and assess their importance for the semantic debate about perspectival expressions, as well as for the claim that perspective matters in putting forward the data on which decisions about the right semantic view are made.

This Open Access book provides both a broad perspective and a focused examination of cow care as a subject of widespread ethical concern in India, and increasingly in other parts of the world. In the face of what has persisted as a highly charged political issue over cow protection in India, intellectual space must be made to bring the wealth of Indian traditional ethical discourse to bear on the realities of current human-animal relationships, particularly those of humans with cows. Dharma, (...) yoga, and bhakti paradigms serve as starting points for bringing Hindu--particularly Vaishnava Hindu--animal ethics into conversation with contemporary Western animal ethics. The author argues that a culture of bhakti--the inclusive, empathetic practice of spirituality centered in Krishna as the beloved cowherd of Vraja--can complement recently developed ethics-of-care thinking to create a solid basis for sustaining all kinds of cow care communities.

Can reasoning improve moral judgments and lead to moral progress? Pessimistic answers to this question are often based on caricatures of reasoning, weak scientific evidence, and flawed interpretations of solid evidence. In support of optimism, we discuss three forms of moral reasoning (principle reasoning, consistency reasoning, and social proof) that can spur progressive changes in attitudes and behavior on a variety of issues, such as charitable giving, gay rights, and meat consumption. We conclude that moral reasoning, particularly when embedded (...) in social networks with mutual trust and respect, is integral to moral progress. (shrink)

Most engineers Fwork within social structures governing and governed by a set of values that primarily emphasise economic concerns. The majority of innovations derive from these loci. Given the effects of these innovations on various communities, it is imperative that the values they embody are aligned with those societies. Like other transformative technologies, artificial intelligence systems can be designed by a single organisation but be diffused globally, demonstrating impacts over time. This paper argues that in order to design for this (...) broad stakeholder group, engineers must adopt a systems thinking approach that allows them to understand the sociotechnicity of artificial intelligence systems across sociocultural domains. It claims that value sensitive design, and envisioning cards in particular, provides a solid first step towards helping designers harmonise human values, understood across spatiotemporal boundaries, with economic values, rather than the former coming at the opportunity cost of the latter.

In this paper, we identify and explain three kinds of bedrock in moral thought. The term "bedrock," as introduced by Wittgenstein in §217 of the Philosophical Investigations, stands for the end of a chain of reasoning. We affirm that some chains of moral reasoning do indeed end with certainty. However, different kinds of certainties in morality work in different ways. In the course of systematizing the different types of certainties, we argue that present accounts of certainties in morality do not (...) reflect their diversity. Our analysis yields three types of moral certainty: QUASI-UNDOUBTABLE CERTAIN PROPOSITIONS, CERTAIN PROPOSITIONS, and TRANSCENDENTAL CERTAINTIES. We show that the first two types can, at least to some extent, be intelligibly doubted. Therefore, they do not possess the characteristics that would classify them as bedrock in the strictest sense. TRANSCENDENTAL CERTAINTIES cannot likewise be doubted because they are rules that enable moral thinking. Thus, deviating from them is unintelligible. We shall argue that all three types reflect ways in which moral language games come to an end, while only one, TRANSCENDENTAL CERTAINTIES, displays the characteristic of being solid bedrock.

Introduction in chapter viii of book ii of An Essay Concerning Human Understanding, John Locke provides various putative lists of primary qualities. Insofar as they have considered the variation across Locke's lists at all, commentators have usually been content simply either to consider a self-consciously abbreviated list (e.g., "Size, Shape, etc.") or a composite list as the list of Lockean primary qualities, truncating such a composite list only by omitting supposedly co-referential terms. Doing the latter with minimal judgment about what (...) terms are co-referential gives us the following list of eleven qualities (in the order in which they appear in this chapter of the Essay): solidity, extension, figure, mobility, motion or rest, number, bulk, texture, motion, size, and situation. Perhaps surprisingly given the attention to the primary/secondary distinction since Locke, Locke's primary qualities themselves have received little more than passing mention in the bulk of the subsequent literature. In particular, no discussion both offers an interpretation of Locke's conception of primary qualities and makes sense of Locke's various lists as lists of primary qualities. A central motivation for this paper is the idea that these two tasks are not independent. (shrink)

Experimental balance is usually understood as the control for the value of the conditions, other than the one under study, which are liable to affect the result of a test. We discuss three different approaches to balance. ‘Millean balance’ requires identifying and equalizing ex ante the value of these conditions in order to conduct solid causal inferences. ‘Fisherian balance’ measures ex post the influence of uncontrolled conditions through the analysis of variance. In ‘efficiency balance’ the value of the antecedent (...) conditions is decided ex ante according to the efficiency they yield in the estimation of the treatment outcome. Against some old arguments by Worrall, we show that in both Fisherian and efficiency balance there are good reasons to randomize the allocation of treatments, in particular when there is no agreement among experimenters as to the antecedent conditions to be controlled for.

This article puts forth a perceptual–phenomenological defence of “thought theory” as a solid solution to the paradox of fiction. Arguing against Kendall Walton’s pretence solution to Charles’s fear and going along the lines of Peter Lamarque’s and Noël Carroll’s thought theory, my proposed defence makes use of the philosophy of a figure who is rarely discussed in the context of phenomenology and never discussed in the context of the paradox of fiction: Leopold Blaustein. To bring forth my proposed perceptual–phenomenological (...) defence, I devise Blaustein’s descriptive account of “perception” and its role in shaping aesthetic experience. Within this line of thought, I further develop a perceptualist reading of Blaustein, paralleling Christine Tappolet’s version, that may be of service to proponents of the “perceptual theory of emotions.”.

Although logical consistency is desirable in scientific research, standard statistical hypothesis tests are typically logically inconsistent. To address this issue, previous work introduced agnostic hypothesis tests and proved that they can be logically consistent while retaining statistical optimality properties. This article characterizes the credal modalities in agnostic hypothesis tests and uses the hexagon of oppositions to explain the logical relations between these modalities. Geometric solids that are composed of hexagons of oppositions illustrate the conditions for these modalities to be logically (...) consistent. Prisms composed of hexagons of oppositions show how the credal modalities obtained from two agnostic tests vary according to their threshold values. Nested hexagons of oppositions summarize logical relations between the credal modalities in these tests and prove new relations. (shrink)

The evidence of laboratory experiments of behavioral economists shows that individuals behave reciprocally. These data put into question the pure self-interest thesis of human motivation of the homo oeconomicus model and call for alternative models. Focusing on the explanation of reciprocal behavior in Trust Games, this article proposes two directions that economists and other social scientists might want to consider in order to establish a more solid foundation for economic theory. First, it presents models that economic theorists developed to (...) explain the laboratory evidence of reciprocal behavior. It highlights that all of these models subscribe to the Humean view that desires are at the source of any human motivation and suggests an alternative Kantian model where reasons have the capacity to motivate human action. Second, it emphasizes that a supplementary examination of the social background conditions would illuminate the analysis of the findings because of the connection between the 'local' and society-wide demands of reciprocity.

Economic models describe individuals in terms of underlying characteristics, such as taste for some good, sympathy level for another player, time discount rate, risk attitude, and so on. In real life, such characteristics change through experiences: taste for Mozart changes through listening to it, sympathy for another player through observing his moves, and so on. Models typically ignore change, not just for simplicity but also because it is unclear how to incorporate change. I introduce a general axiomatic framework for defining, (...) analysing and comparing rival models of change. I show that seemingly basic postulates on modelling change together have strong implications, like irrelevance of the order in which someone has his experiences and ‘linearity’ of change. This is a step towards placing the modelling of change on solid axiomatic grounds and enabling non-arbitrary incorporation of change into economic models. (shrink)
