Articolo divulgativo pubblicato nella rivista l'Indiscreto il 1 settembre 2021. Riccardo Manzotti è uno dei più originali filosofi della mente in Italia. La sua teoria, per la quale mondo e mente sono identici, può ricordare il nuovo realismo di Edwin B. Holt. Come ogni filosofo, però, Manzotti ha anche molte idee: in epistemologia, etica, e negli altri àmbiti della metafisica. In questa intervista, ho voluto andare oltre la sua nota teoria sulla mente, per mostrare gli altri aspetti della (...) sua filosofia. (shrink)

Recent scholarship has considered the requirements of justice and economic regimes in the work of John Rawls. This work has not delved into the requirements of justice and liberal socialism as deeply as the work that has been done on property-owning democracy. A thorough treatment of liberal socialism and the requirements of justice is needed. This paper seeks to begin to fill this gap. In particular, it needs to be shown if liberal socialism fully answers the requirements of justice better (...) than property-owning democracy. It will be argued that liberal socialism does significantly better in realizing the two principles. This paper has the following structure, first, an overview of Rawls' position on economic regimes, capitalism, and the requirements of justice will be presented. In particular, how the two principles work in tandem to meet the demands of distributive justice will be considered. Second, a review of property-owning democracy will be conducted. Finally, liberal socialism will be examined and discussed as an economic regime that answers the requirements of justice more fully. (shrink)

Decommodification is an important support for the development of our excellences and the pursuit of our freedom of conscience. In order to show this, the paper will be structured as follows. First, it will be argued that a decommodified social threshold of goods and services is a necessary part of a free-standing politically liberal conception of justice. The authors to be reviewed in this section are R.H. Tawney and John Rawls. The second section will discuss a compendium of possible decommodified (...) goods and services. Finally, an alternative of partial decommodification and a brief comment on basic income grants will be presented in the last sections. (shrink)

In his Republic, Plato argues that self-rulership cannot be widespread enough in a populace due to structural failures of education. This means that rulership by the few with the use of manipulative mythological devices is inevitable. That is, if a populace cannot rule themselves through the use of their reason, then they will be ruled by others through the use of myth, at best, and at worst, violence. Even given this rather grim conclusion, if we closely examine what Plato has (...) to say about politics, we can see that there is no natural impossibility for generalized rule by the many. That is, there is no aristocracy of birth, but there is an aristocracy of the educated. As I will show below, we can develop a more democratic politics out of Plato if we consider the possibility of a democratic education. Before I do that, I will briefly consider Rawls’ comments on the education of citizens for democracy. This will allow for a clearer consideration of the democratic potential of Plato’s political philosophy in his Republic. (shrink)

Abstract: This paper restates the thesis of 'The Requirements of Justice and Liberal Socialism" where it was argued that liberal socialism best meets Rawlsian requirements of justice. The recent responses to this paper by Jan Narveson, Jeppe von Platz, and Alan Thomas merit examination and comment. This paper shows that if Rawlsian justice is to be met, then non-personal property must be subject to public control. If just outcomes merit the public control of non-personal property and this control is not (...) utilized, then justice has been subordinated to the objectively less important institution of private property.

Modern money theory is a conjecture concerning fiscal spending and the nature of money. I show that modern money theory provides two interesting insights into distributive justice that have not been addressed in the recent Anglo-American distributive justice literature: (i) that the nature of a sovereign fiat currency allows for some distributive conflicts to be avoided; and (ii) that recent Anglo- American distributive justice theories assume that the economy is at capacity. Based on this, I consider if the policy results (...) of modern money theory can help foster a sense of justice. (shrink)

Modern Monetary Theory and Distributive Justice shows how the macroeconomic framework called modern money theory (MMT) is relevant to the field of political philosophy called distributive justice. Many of the macroeconomic assumptions of distributive justice are unstated and unexamined. The framework of MMT illuminates these assumptions and provides an alternative vision of distributive justice analysis and prescriptions. In particular, MMT holds that modern money is a nominal state issued token (fiat), there is a distinction between nominal assets and real assets, (...) that state money as a nominal token can cause changes in real terms, and that the macroeconomy has historically not operated at capacity. The upshot of these assumptions held by MMT is that state spending can bring about changes in persons’ well-being without traditional redistributive measures via taxation. This is in contradistinction to standard assumptions in the distributive justice literature, which holds that the macroeconomy is at capacity and, thus, redistribution is the necessary mechanism for enacting improvements in well-being. This is a fundamental shift in how distributive justice can be conceived. (shrink)

Rawls’s consideration not to include the choice of economic systems as part of a theory of justice is inconsistent with his comments on redistribution and the political effects of economic inequality. When Rawls’s discussion of economic systems and his discussion of economic inequalities is examined, it is apparent that the selection of economic systems is a pertinent topic for a theory of justice. The propensity for the primary social good of self-respect to be satisfied can be affected by the selection (...) of economic systems. Rawls has incorrectly determined the selection of economic systems to be unimportant if different economic systems can be more advantageous to the satisfaction of self-respect than others. When socialism and Rawls’s version of regulated capitalism are compared, socialism is a maximin solution, and accordingly will be selected by people within the original position under the veil of ignorance.

The study assessed the conceptual understanding and attitude toward fractions of teacher education students in a socio-constructivist learning environment. Specifically, it determined the students’ level of conceptual understanding before and after instruction; verified the types of conceptual changes that occurred; and ascertained the attitude of students toward fractions before and after instruction and its relationship to their levels of understanding. Descriptive-correlational research method was used. Socio-constructivist context-based teaching method was employed to introduce the concept of fractions. Achievement tests and interviews (...) were administered to determine the students’ level of conceptual understanding. Conceptual analysis based on Jensen and Finley’s (1995) method with Tiberghien’s (1994) classification of changes was utilized to describe students’ conceptual understanding and conceptual changes. In order to determine their attitude on fractions, students were asked to answer the socio-constructivist attitude questionnaire. The level of conceptual understanding of teacher education students in fraction was functional misconception and partial understanding before and after instruction, respectively. The type of conceptual change that occurred among teacher education students was change for the better. Socio-constructivist learning more likely to improve students’ attitudes toward fractions; promoted prosocial behavior among students; and tend to increase students’ activeness in the classroom activities as evidenced.

G.A. Cohen attempts to provide a case for socialism that takes into consideration the reasons why socialism is desirable and some of the problems for its feasibility. He finds that the kind of community sentiment that socialism requires is possible, but the devices of social organization that can facilitate the growth of socialist sentiment along with the effective transmission of information are not currently known. In short, Cohen thinks social scientists and philosophers need to find out how to harness the (...) information transmission capacity of market exchange without the motivational encouragement of rapacious self-interest that market exchange fosters. This paper argues that Cohen’s appraisal of the ineffectiveness of informational transmission in socialist planned economies in incorrect. A democratically planned socialist economy can serve as the basis for the fostering of the socialist community sentiment that Cohen advocates along with the required transmission of economic information.

This paper will examine the three distributive problems of inequality, social scarcity, and environmental decay. All three of these problems are the result of economic growth that is not properly structured by institutions. It will be argued that each one of these distributive problems exacerbates the other two. Any solution to one of these problems must address the other two as well. This paper will show that these three distributive problems can be minimized through a combination of tax measures, institutional (...) changes, public employment creation, public service provision, and the nationalization of certain industries.

G.A. Cohen’s critique of the Rawlsian difference principle points out an inconsistency in its presentation. The initial equality decided by the participants in the original position under the veil of ignorance is not preserved by the inequality sanctioned by the difference principle. Cohen shows how the breakdown of the initial equality of the original position prevents the desired results of the Rawlsian system from being realized. Cohen argues that an egalitarian ethos is required within a society for equality preserving economic (...) distributions and Pareto superior outcomes to occur. Nonetheless, Cohen’s analysis of Rawls misses the ultimate cause of inequality, which is the dynamics of capital accumulation. An egalitarian ethos is only possible if there is a socialist mode of production to facilitate its development. Additionally, Cohen’s critique of Rawlsian constructivism through an argument for intuitionism does not address the natural-material existence of human beings. This existence must be considered for any advantageous social formation. (shrink)

A psychological study of thought and language which takes an exposition of scientific linquistics as a point of departure.

This paper has two aims. First, it sets out an interpretation of the relevant logic E of relevant entailment based on the theory of situated inference. Second, it uses this interpretation, together with Anderson and Belnap’s natural deduc- tion system for E, to generalise E to a range of other systems of strict relevant implication. Routley–Meyer ternary relation semantics for these systems are produced and completeness theorems are proven. -/- .

My real position is that logic is a mere sub-branch of rhetoric, but in this paper I only try to show an area of overlap. Certain usages in logical work are metaphorical, and I argue that this has pernicious effects in a discipline assumed strictly literal. Among these pernicious effects are the bizarre and fruitless focus of philosophy of mathematics on the pseudo-problems of foundations and objects. I mostly examine the locution 'logical construction' and a range of associated metaphors. Some (...) sketchy remarks on the history of rhetoric are offered in explanation. (shrink)

Hun Chung’s recent article “Rawls’s Self-Defeat: A Formal Analysis” argues that the selection of results equivalent to justice as fairness can be derived by utilitarianism. Chung argues that these results can be achieved through the use of Rawls’s constructed utility function from his work Justice as Fairness. Although Chung’s article is finely argued and presented in great detail, this paper will show that Chung made three mistakes in the fundamentals of his argument. First, Chung mistakes Rawls’s constructed utility function as (...) actually utilitarian. Second, Chung confuses the motivations and the assumptions of those held by agents in the original position and those held by utilitarian agents. Last, Chung’s previous mistakes result in the incorrect conclusion that an equal distribution of resources will be selected by representative agents instead of the unequal distribution prescribed by the difference principle.

Harm is a concept in philosophy that has been able to elude definition. Many attempts have been made to formulate a definition of harm, however they have all been futile. This has led many to question if it is even possible to define harm, or if we really even need a definition of harm? My answer to both of these questions is yes, harm is something that is worth caring about and has many practical implications in society today. The theories (...) of harm that have been the closest thus far have been comparative accounts of harm, which compare different states of the agent undergoing the harm. The most common of these comparative accounts has been the counterfactual comparative account of harm. This approach has faced many problems like preemption, overdetermination, and omission. I argue the comparative account of harm is correct, but the wrong comparison is being made. Instead of a counterfactual comparison we should make a temporal comparison, and evaluate whether or not the agent has become worse off than he or she was before the harming event occurred. First I will use Bradley’s model to sketch a brief definition checklist of harm. I will then briefly evaluate a general counterfactual theory of harm and illustrate why it falls short. Next I will pose the temporal comparative account of harm , and explain how it gets around the counterexamples that tripped up the counterfactual approach. Finally I will present some objections to TCA, and try to respond to them. (shrink)

In this article I argue that it is underdetermined what Spinoza is arguing for when he says in Proposition 72 of Part IV of the Ethics that (translated) "A free man never acts deceitfully, but always in good faith." In "Spinoza, Lying, and Acting in Good Faith," John Bauer has argued that Spinoza lays down an absolute moral prohibition never to lie.

The potential benefits of cognitive skills in enhancing mathematics ability have been claimed by numerous researchers. Since mathematics requires a complete understanding and grasp of abstract concepts, it is essential to explore how learning with metacognitive skills affects mathematics learning. Thus, the study investigates the students' metacognitive awareness and conceptual understanding of integers. A descriptive-correlational method approach was utilized, and it was carried out on 303 seventh-grade students. The data were obtained using a metacognitive awareness inventory and achievement test on (...) integers. It was further revealed that the students have average metacognitive awareness and performed well in the fundamental operation of integers. Follow-up qualitative analysis revealed that students who were high achievers had the best understanding, average achievers had corrected or incomplete understanding, and low achievers had a functional misconception of integers. Moreover, the student's metacognitive awareness was significantly related to their conceptual understanding of integers. This indicates that student's higher-order thinking skills, such as metacognition, are essential since they are associated with building conceptual skills. Thus, teachers should encourage students' metacognitive awareness to improve students' conceptual understanding of integers. The study provides relevant information for educational managers on the potential factors to be considered in improving mathematics education practices, particularly in promoting metacognition among high school students.

Mathematics is considered one of the most challenging courses for many elementary pre-service teachers (EPTs). In hopes for improvement, teacher educators have been incorporating a jigsaw strategy to equip future teachers with the necessary competencies. Hence, the study aimed to determine the effectiveness of the jigsaw strategy with EPTs’ level of mathematics achievement and interest in an online cooperative learning environment. The research utilized a pre-experimental design with 40 participants. The researchers used pretest and posttest questions covering fraction operations and (...) a mathematics interest questionnaire before and after the intervention. With the implementation of the jigsaw strategy, results showed that the EPTs’ mathematics achievement improved while their interest in mathematics improved to some extent. Likewise, a significant difference between the pre-and post-intervention concerning the EPTs’ mathematics achievement and interest in mathematics was found. Furthermore, correlation analysis revealed that study time is negatively related to mathematics achievement, as is the overall level of interest in mathematics. These findings imply that a jigsaw strategy is a useful tool in teaching mathematics online. However, several modifications may be considered to recognize that the EPTs’ interest in mathematics varies from one person to another. Teacher education institutions are encouraged to apply this strategy not only for EPTs to increase their mathematical know-hows but also to serve as an example for them to employ in their future teaching careers.

The study determined the problem-solving performance and skills of prospective elementary teachers (PETs) in the Northern Philippines. Specifically, it defined the PETs’ level of problem-solving performance in number sense, measurement, geometry, algebra, and probability; significant predictors of their problem-solving performance in terms of sex, socio-economic status, parents’ educational attainment, high school graduated from and subject preference; and their problem-solving skills. The PETs’ problem-solving performance was determined by a problem set consisting of word problems with number sense, measurement, geometry, algebra, and (...) probability. A mixed-method research design was employed. Senior PETs purposively served as a sample where they mostly preferred to teach other subjects than mathematics. PETs who preferred math performed satisfactorily, while prospective teachers who opted for other subjects performed unsatisfactorily. The PETs’ unsatisfactory output indicates the need for remediation to advance the mathematical material skills and enrich the problem-solving abilities of these primary schools' potential teachers. Besides, results showed that subject preference strongly affected and predicted the problem-solving success of the PETs. PETs who preferred to teach mathematics performed significantly better than their counterparts; hence, mathematics as a field of specialization in the Bachelor of Elementary Education program may be considered by teacher education institutions. Further, most PETs displayed lack of problem-solving skills; thus, a Problem-Solving course is recommended for them. (shrink)

According to Kantians, coercion and deception are the two fundamental kinds of wrongdoing. Although this may be true, I wish to argue against two other related assumptions about coercion and deception held by Kantians as well as non-Kantians. One is the assumption that coercion is morally worse than deception, all things being equal. The other is the assumption that whenever coercion is morally permissible, deception is morally permissibe, all things being equal. Both of these assumptions, I argue, are false. Deception (...) is morally worse than coercion, and deception is never morally permissible in virtue of the fact that coercion is morally permissible, whenever coercion is morally permissible.

Mathematical modeling offers a promising approach to improving mathematics education. This study aims to determine if the concept of metacognitive awareness in the learning process is associated with mathematical modeling. This study also considers the interaction effect of sex and academic year level on both variables. Focusing the study on preservice elementary teachers might address potential issues and targeted intervention in their preparation program concerning their ability to teach and guide young learners in modeling activities. The research sample includes 140 (...) preservice elementary teachers at Central Luzon State University, Philippines. Data collection used an adapted metacognitive awareness inventory and a validated researcher-made mathematical modeling competency test aligned with the K-12 mathematics curriculum in the Philippines. Results revealed that the preservice elementary teachers had a high metacognitive awareness and mathematical modeling competency, ranging from 22 to 31 out of 36 points. Besides, Factorial ANOVA indicates that academic year level positively affects both variables regardless of sex, and stepwise regression analysis unveiled that information management, declarative knowledge, and planning significantly predict 41.4% of the mathematical modeling competency variance. This suggests that developing metacognitive awareness supports preservice elementary teachers in performing modeling tasks that improve their competency level in mathematics. (shrink)

This dissertation explains Karl Marx’s understanding of nature, human action, and a materialist standard of practical action. Marx’s understands natural processes as not identical with human action. There are two types of human action for Marx: material action and social action. Material action can use natural processes. Social action does not directly use natural processes, but social action can promote how material action uses natural processes. The difference between natural processes, material action, and social action is important for Marx since (...) it: maintains the independent reality of nature, maintains the development of material accomplishments as separate from social forms, and demonstrates the transitory status of social forms. This difference between material action and social action allows Marx to criticize certain social forms while praising the productive possibilities of the current level of technical development. A practical standard is developed using Marx’s understanding of nature and human action. This practical standard is based on humans’ necessary relationship to natural processes. Beneficial outcomes according to humans’ material abilities and their existence as natural beings is established by application of the practical standard. The materialist standard of practical action can be understood as an ethical theory that is not based on traditional ethical criteria. (shrink)

A logic is called 'paraconsistent' if it rejects the rule called 'ex contradictione quodlibet', according to which any conclusion follows from inconsistent premises. While logicians have proposed many technically developed paraconsistent logical systems and contemporary philosophers like Graham Priest have advanced the view that some contradictions can be true, and advocated a paraconsistent logic to deal with them, until recent times these systems have been little understood by philosophers. This book presents a comprehensive overview on paraconsistent logical systems to change (...) this situation. The book includes almost every major author currently working in the field. The papers are on the cutting edge of the literature some of which discuss current debates and others present important new ideas. The editors have avoided papers about technical details of paraconsistent logic, but instead concentrated upon works that discuss more 'big picture' ideas. Different treatments of paradoxes takes centre stage in many of the papers, but also there are several papers on how to interpret paraconistent logic and some on how it can be applied to philosophy of mathematics, the philosophy of language, and metaphysics.

This study determined the cognitive skills achievement in mathematics of elementary pre-service teachers as a basis for improving problem-solving and critical thinking which was analyzed using Piaget's seven logical operations namely: classification, seriation, logical multiplication, compensation, ratio and proportional thinking, probability thinking, and correlational thinking. This study utilized an adopted Test on Logical Operations (TLO) and descriptive research design to describe the cognitive skills achievement and to determine the affecting factors. Overall, elementary pre-service teachers performed with sufficient understanding in dealing (...) with the TLO. However, in each logical operation, students were found to have insufficient understanding of probability thinking and correlational thinking. These insufficiencies in other logical operations were attributed to their misconceptions on some mathematical terms, misinterpretation of the problems, poor comprehension skills, poor problem-solving skills, and poor performance in mathematics in general.

In today’s fast-changing educational settings, technology integration offers the opportunity to enhance mathematics instruction. This study determines the significant socio-cognitive factors among preservice mathematics teachers (PMTs) affecting their behavioral intention toward the use of technology. A descriptive-correlational research design was employed with 130 participants. Revised UTAUT construct items and behavioral intention scales were utilized through survey forms. Findings revealed that the participants were more inclined to use technology in their pedagogical approach. The only socio-cognitive factors significantly affecting the participants’ positive (...) inclination to utilize educational technology were performance expectancy, effort expectancy, and social influence. However, when controlling for the effects of the participants’ willingness to use technology, social influence became insignificant. Developing favorable impressions of technology’s effectiveness and ease of use may encourage greater technology integration in mathematics education. (shrink)

The INBIOSA project brings together a group of experts across many disciplines who believe that science requires a revolutionary transformative step in order to address many of the vexing challenges presented by the world. It is INBIOSA’s purpose to enable the focused collaboration of an interdisciplinary community of original thinkers. This paper sets out the case for support for this effort. The focus of the transformative research program proposal is biology-centric. We admit that biology to date has been more fact-oriented (...) and less theoretical than physics. However, the key leverageable idea is that careful extension of the science of living systems can be more effectively applied to some of our most vexing modern problems than the prevailing scheme, derived from abstractions in physics. While these have some universal application and demonstrate computational advantages, they are not theoretically mandated for the living. A new set of mathematical abstractions derived from biology can now be similarly extended. This is made possible by leveraging new formal tools to understand abstraction and enable computability. [The latter has a much expanded meaning in our context from the one known and used in computer science and biology today, that is "by rote algorithmic means", since it is not known if a living system is computable in this sense (Mossio et al., 2009).] Two major challenges constitute the effort. The first challenge is to design an original general system of abstractions within the biological domain. The initial issue is descriptive leading to the explanatory. There has not yet been a serious formal examination of the abstractions of the biological domain. What is used today is an amalgam; much is inherited from physics (via the bridging abstractions of chemistry) and there are many new abstractions from advances in mathematics (incentivized by the need for more capable computational analyses). Interspersed are abstractions, concepts and underlying assumptions “native” to biology and distinct from the mechanical language of physics and computation as we know them. A pressing agenda should be to single out the most concrete and at the same time the most fundamental process-units in biology and to recruit them into the descriptive domain. Therefore, the first challenge is to build a coherent formal system of abstractions and operations that is truly native to living systems. Nothing will be thrown away, but many common methods will be philosophically recast, just as in physics relativity subsumed and reinterpreted Newtonian mechanics. -/- This step is required because we need a comprehensible, formal system to apply in many domains. Emphasis should be placed on the distinction between multi-perspective analysis and synthesis and on what could be the basic terms or tools needed. The second challenge is relatively simple: the actual application of this set of biology-centric ways and means to cross-disciplinary problems. In its early stages, this will seem to be a “new science”. This White Paper sets out the case of continuing support of Information and Communication Technology (ICT) for transformative research in biology and information processing centered on paradigm changes in the epistemological, ontological, mathematical and computational bases of the science of living systems. Today, curiously, living systems cannot be said to be anything more than dissipative structures organized internally by genetic information. There is not anything substantially different from abiotic systems other than the empirical nature of their robustness. We believe that there are other new and unique properties and patterns comprehensible at this bio-logical level. The report lays out a fundamental set of approaches to articulate these properties and patterns, and is composed as follows. -/- Sections 1 through 4 (preamble, introduction, motivation and major biomathematical problems) are incipient. Section 5 describes the issues affecting Integral Biomathics and Section 6 -- the aspects of the Grand Challenge we face with this project. Section 7 contemplates the effort to formalize a General Theory of Living Systems (GTLS) from what we have today. The goal is to have a formal system, equivalent to that which exists in the physics community. Here we define how to perceive the role of time in biology. Section 8 describes the initial efforts to apply this general theory of living systems in many domains, with special emphasis on crossdisciplinary problems and multiple domains spanning both “hard” and “soft” sciences. The expected result is a coherent collection of integrated mathematical techniques. Section 9 discusses the first two test cases, project proposals, of our approach. They are designed to demonstrate the ability of our approach to address “wicked problems” which span across physics, chemistry, biology, societies and societal dynamics. The solutions require integrated measurable results at multiple levels known as “grand challenges” to existing methods. Finally, Section 10 adheres to an appeal for action, advocating the necessity for further long-term support of the INBIOSA program. -/- The report is concluded with preliminary non-exclusive list of challenging research themes to address, as well as required administrative actions. The efforts described in the ten sections of this White Paper will proceed concurrently. Collectively, they describe a program that can be managed and measured as it progresses. (shrink)

Proficiency in solving mathematical problems is essential for preservice elementary teachers, as they will teach foundational math concepts and foster problem-solving abilities among young learners. However, many studies found low problem-solving performance among preservice teachers. In line with this, the present study examined how problem-solving disposition relates to the performance of preservice elementary teachers, conducted at a selected higher education institution in Nueva Ecija, Philippines, with 134 participants. The study utilized a mathematical problem-solving disposition and beliefs scale questionnaire and a (...) problem-solving test scored using the identify, define, explore, act, and look (IDEAL) model. Results indicated an average problem-solving disposition and high problem-solving performance among preservice teachers. Linear regression analysis showed that overall problem-solving disposition is a predictor of performance. Further, stepwise regression analysis revealed that two disposition parameters, mathematical mindset (β = 2.413, p < 0.01) and community of practice (β = 1.866, p < 0.01), significantly predicted problem-solving performance. These findings show the significance of developing a problem-solving disposition, mindset, and learning communities to improve future teachers’ problem-solving ability by providing more learning opportunities, interdisciplinary problems, and social engagements.

Using the KenKen puzzle may improve students’ performance in operating integers. Quasi-experimental research was conducted to determine the effectiveness of this intervention on the performance and attitude of students in a collaborative learning environment. One hundred four purposively selected Grade 7 students in Nueva Ecija served as respondents and the experimentation lasted four days following the K to 12 Learners Manual. An increase in the student’s performance was found after utilizing the KenKen puzzle, where a significant difference between the posttest (...) and pretest was recorded after the four days of utilization of the puzzle. Besides, students’ attitude toward operating integers showed positivity as it is enjoyable, interesting, challenging, and developing creativity and critical thinking. Moreover, a strong relationship was found between the students’ performance and attitude in operating integers. This suggests that the KenKen puzzle helped improve the students’ performance and attitude in operating integers in a collaborative learning environment. (shrink)

In this book chapter I argue that contrary to what is said by Paul Guyer in Kant (Routledge, 2006) Kant's moral philosophy prohibits the bystander from throwing the switch to divert the runaway trolley to a side track with an innocent person on it in order to save more people who are in the path of the trolley in the "Trolley Problem" case made famous by Judith Jarvis Thomson (1976; 1985). Furthermore, Thomson herself (2008) came to agree that it would (...) be wrong to throw the switch, just as it is wrong to push the person off the bridge to stop the trolley (1976; 1985). In changing her mind about this case, Thomson came to agree with Kant as well as with Philippa Foot (1967) who argued in her original paper that a negative duty not to harm one healthy patient outweighed a positive duty to give aid to five other patients by transplanting the healthy person's organs.

In this essay I argue that Shelley's "A Defense of Poetry" is best understood as a defense of poetic language, which is in turn best understood as a defense of metaphorical language. According to Shelley, the metaphors of the poets reveal (extra-linguistic) reality, and have a truth value – they are true insofar as they capture reality. The literal language of "mere reasoners" of science and philosophy, by contrast, only reveals relations between ideas already known, and their statements are true (...) in virtue of the meanings of the words. Shelley's essays has been misunderstood because writers on metaphor such as David Cooper and Richard Rorty have assumed that metaphors are neither true nor false, and that defenders of metaphorical language such as Shelley are defending non-truth-apt language. Even those writers on metaphor who believe that metaphors are truth-apt, such as Raymond Gibbs, fail to understand that Shelley should be included in their number. (shrink)

In this chapter I argue that there are three different senses of 'lie' in Kant's moral philosophy: the lie in the ethical sense (the broadest sense, which includes lies to oneself), the lie in the 'juristic' sense (the narrowest sense, which only includes lies that specifically harm particular others), and the lie in the sense of right (or justice), which is narrower than the ethical sense, but broader than the juristic sense, since it includes all lies told to others, including (...) those who are bent on harming innocent others.

In this article Judith Jarvis Thomson's Good Samaritan Argument in defense of abortion in the case of rape is defended from two objections: the Kill vs. Let Die Objection, and the Intend to Kill vs. Merely Foresee Death Objection.

In contrast to the successful previous year, 2020 turned out to be difficult, not only for the earth’s population due to COVID-19 but also for JDDM with an unusually small sixth volume.

In this paper I argue that, although Kant argues that morality is independent of God (and hence, agrees with the Euthyphro), and rejects Divine Command Theory (or Theological Voluntarism), he believes that all moral duties are also the commands of God, who is a moral being, and who is morally required to punish those who transgress the moral law: "God’s justice is the precise allocation of punishments and rewards in accordance with men’s good or bad behavior." However, since we lack (...) a strict proof of God's existence, we can still fulfill our duties from the motive of duty. if we did know that God exists, then this would undermine our pure moral motivation to do our duty, since we would have an even stronger interest in pleasing God through our good conduct. The effect of undermining our pure moral motivation would be to make us less eligible for divine reward, since God rewards us for doing our duty from the motive of duty. (shrink)

Short survey of philosophical literature on the definition of lying and the ethics of lying.

In this review of John Shand's book on the history of western philosophy, I point out that the book is only concerned with epistemology and metaphysics, and only considers in detail the work of twenty individual philosophers.

Within these (...) narrow limits, Shand does an excellent job of presenting the epistemology and metaphysics of each major philosopher considered. (shrink)

In this essay I argue that Ridley Scott's first feature film, The Duelists, which is an adaptation of a Joseph Conrad novella, contains his deepest meditation on honor in his entire career. The film may be said to answer the following question about honor: is being bound to do something by honor, when it is contrary to one's self-interest, a good thing, or a bad thing? It may be said to give the answer that it may be either good or (...) bad. It is bad that D'Hubert is bound by honor to duel with Feraud; it is good that, in the end, Feraud is bound by honor to cease dueling with D'Hubert. In this way, Kant was correct that "the inclination to honor" may light "upon that which is in fact in the common interest and in conformity with duty," or it may light upon what is contrary to duty.

Abstract: The concept of debt financing has assumed considerable importance in recent years given the fundamental role debts now play in forming the financial structure of corporate firms. Quite evident in the debt finance literature is the juxtaposition between debt financing and corporate performance which suggests that debt financing can influence corporate performance. Against the narrow measures of debt financing which are common with most studies that have been carried out on the debt finance-performance dynamics; we attempted a more robust (...) combination of debt finance choices in modelling for corporate performance. Based on data gleaned from the audited annual reports of fifteen (15) consumer goods firms listed in the Nigerian Stock Exchange (NSE) for the period 2006 to 2017, results of the panel regression technique revealed that total debt, long-term debt and short-term debt to asset ratios positively influence the performance of consumer goods firms in Nigeria. Based on the findings of the study, we recommend, among others, that there is need for the Nigerian firms to rely less on short-term debts, which forms the major part of their leverage, and focus more on developing internal strategies that can help improve their performance.

In this essay I argue that Machiavelli does not hold that all deception is permissible in war. While Machiavelli claims that "deceit... in the conduct of war is laudable and honorable," he insists that such deceit, or ruses of war, is not to be confounded with perfidy. Any Lee's U.S. Civil War film, "Ride With the Devil," illustrates this difference. The film also illustrates the difference between lying as part of romance, which is permitted, and lying at the moment of (...) truth in a relationship, when admitting one's feelings, which is not.

We are quickly passing through the historical moment when people work in front of a single computer, dominated by a small CRT and focused on tasks involving only local information. Networked computers are becoming ubiquitous and are playing increasingly significant roles in our lives and in the basic infrastructure of science, business, and social interaction. For human-computer interaction o advance in the new millennium we need to better understand the emerging dynamic of interaction in which the focus task is no (...) longer confined to the desktop but reaches into a complex networked world of information and computer-mediated interactions. We think the theory of distributed cognition has a special role to play in understanding interactions between people and technologies, for its focus has always been on whole environments: what we really do in them and how we coordinate our activity in them. Distributed cognition provides a radical reorientation of how to think about designing and supporting human-computer interaction. As a theory it is specifically tailored to understanding interactions among people and technologies. In this article we propose distributed cognition as a new foundation for human-computer interaction, sketch an integrated research framework, and use selections from our earlier work to suggest how this framework can provide new opportunities in the design of digital work materials.

Mindset plays a vital role in tackling the barriers to improving the preservice mathematics teachers’ (PMTs) conceptual understanding of problem-solving. As the COVID-19 pandemic has continued to pose a challenge, online learning has been adopted. This led this study to determining the PMTs’ mindset and level of conceptual understanding in problem-solving in an online learning environment utilising Google Classroom and the Khan Academy. A quantitative research design was employed specifically utilising a descriptive, comparative, and correlational design. Forty-five PMTs were chosen (...) through simple random sampling and willingly took part in this study. The data was gathered using validated and reliable questionnaires and problem-solving tests. The data gathered was analysed using descriptive statistics, analysis of variance, and simple linear regression. The results revealed that the college admission test, specifically numerical proficiency, influences a strong mindset and a higher level of conceptual understanding in problem-solving. Additionally, this study shows that mindset predicts the levels of conceptual understanding in problem-solving in an online environment where PMTs with a growth mindset have the potential to solve math problems. The use of Google Classroom and the Khan Academy to aid online instruction is useful in the preparation of PMTs as future mathematics teachers and problem-solvers. Further studies may be conducted to validate these reports and to address the limitations of this study. (shrink)

Extended Essay Review of the 26 chapters in the collection Global Epistemologies and Philosophies of Science, Routledge, 2021.

In this article I reject the argument of Colin McGinn ("Must I Be Morally Perfect?", 1992) that ordinary morality requires that each of us be morally perfect. McGinn's definition of moral perfection –– according to which I am morally perfect if I never do anything that is supererogatory, but always do what is obligatory, and always avoid doing what is impermissible –– should be rejected, because it is open to the objection that I am morally perfect if I always do (...) what is optional but bad to do (what is suberogatory), in addition to always doing what is obligatory and always avoiding what is impermissible. Moral perfection may be defined as always doing what is obligatory, and always doing what is optional but good to do (supererogatory), and never doing what is impermissible, and never doing what is optional but bad to do [suberogatory]. Since ordinary morality does not require this, ordinary morality does not require moral perfection. (shrink)

In this review of Brooke Harrington's edited collection of essays on deception, written by people from different disciplines and giving us a good "status report" on what various disciplines have to say about deception and lying, I reject social psychologist Mark Frank's taxonomy of passive deception, active consensual deception, and active non-consensual deception (active consensual deception is not deception), as well as his definition of deception as "anything that misleads another for some gain" ("for gain" is a reason for engaging (...) in deception, not part of its definition). I also take issue with management professor Guido Mollering's claim that all deception involves a violation of trust. (shrink)
