As the world’s population grows and urbanization continues, the global waste crisis is becoming more severe, especially in developing countries. Without proper waste management, they may encounter various environmental and health risks. Biological technologies are regarded as promising waste management and recycling approaches in developing countries due to their cost-effectiveness and capability to handle diverse waste categories. One prominent technology in this aspect is the vermicomposting of organic waste utilizing the black soldier fly larvae. Nevertheless, (...) significant financial resources are still necessary to advance and expand biological waste treatment, which requires the participation of businesses. By examining waste management companies listed on the Vietnamese stock market, we highlight two challenges that hinder the adoption and scaling of the waste treatment system using black soldier flies and potentially other biological technologies in Vietnam. Specifically, the business regards the environmental services they offer primarily as a means to generate profit rather than as a genuine commitment to environmental preservation, and the values of companies operating in the environmental sector, particularly in waste management, have been significantly undervalued by the Vietnamese investing public. Therefore, we advocate for societal shifts toward the eco-surplus culture and apply the semiconducting principle of monetary and environmental values exchange to address the problem. (shrink)

According to the orthodox view, the goodness of a life depends exclusively on the things that actually happened within it, such as its pleasures and pains, the satisfaction of its subject’s preferences, or the presence of various objective goods and bads. In this paper, I argue that the goodness of a life also depends on what could have happened, but didn’t. I then propose that this view helps us resolve ethical puzzles concerning the standards for a life worth living for (...) animals and the significance of a life’s shape. (shrink)

E-waste is one of the most pressing challenges of our time, yet it is often ignored, especially in Southeast Asia. The “tsunami of e-waste” in the region has been putting our lives and our environment at risk. With the extensive use of electrical and electronic devices, we are also contributing to harming the environment and quickening the climate change by producing and discarding e-waste. Youths are among major users of electronic devices, and hunger for upgraded and newer (...) versions. -/- However, there is still a lack of sensitization on e-waste management issues in the Southeast Asia region. Why should not the young people be pioneers in educating this challenge to the young public? Our FRE-E-WASTE project team is firm in our belief that youths should take the lead in bringing to light this aspect of climate justice, to the best of our ability. -/- Implemented by a group of ASEAN environmental enthusiasts, STEP Forward Education and supported by the U.S. Department of State and the Young Southeast Asian Leaders Initiative (YSEALI), FRE-E-WASTE Project seeks to bring together a group of Southeast Asian environmental enthusiasts aged between 18 and 35 to connect and collaborate on e-waste issues in the region and eventually to create a toolkit about e-waste for the Southeast Asia region.

In this paper, we argue that our moral concern for future well-being should reduce over time due to important practical considerations about how humans interact with spacetime. After surveying several of these considerations (around equality, special duties, existential contingency, and overlapping moral concern) we develop a set of core principles that can both explain their moral significance and highlight why this is inherently bound up with our relationship with spacetime. These relate to the equitable distribution of (1) moral concern in (...) a universe that we can only causally affect in one temporal direction; (2) access to the benefits from using spacetime as a resource; and (3) the burdens of care given (1) and (2). We conclude by considering the practical implications of our argument and find that, while it is often assumed that a preference for present over future well-being weakens the case for existential risk mitigation, this likely is not the case.

This article sheds light on managing and utilizing scientific and technological funds (Sci-Tech funds) in Vietnam.

A group of researchers led by QV Khuc of Hanoi-based Vietnam National University has just published a new paper concerning plastic waste and households’ tackling strategies in Vietnam.

This paper argues that there is a conflict between two principles informing Locke’s political philosophy, namely his waste restriction and his strong voluntarism. Locke’s waste restriction is proposed as a necessary, enforceable restriction upon rightful private property holdings and it yields arguments to preserve and redistribute natural resources. Locke’s strong voluntarism is proposed as the liberal ideal of political obligations. It expresses Locke’s view that each individual has a natural political power, which can only be transferred to a (...) political body through the individual’s voluntary, actual consent. On this view, the legitimacy of a political power is dependent upon its subjects’ actual consent to its authority. After briefly outlining these two ideas informing Locke’s conception, I argue that we cannot maintain both at the same time. Therefore, contemporary Lockeans must either derive restrictions upon private property concerned with preserving natural resources from other aspects of Locke’s theory or they must accept weak voluntarism as the ideal of political obligations. I argue that both alternatives pose significant problems for the Lockean project. (shrink)

The view that metaphysics is a waste of time appears to be gaining in popularity. It is held openly by many scientists and even many philosophers. I argue here that this is a consequence of the way metaphysics is usually done and the futility of a certain approach to it, and not a reason to suppose there is no useful knowledge to be acquired from its study. -/- .

In this paper, I first argue that waste is best understood as (a) any process wherein something useful becomes less useful and that produces less benefit than is lost—where benefit and usefulness are understood with reference to the same metric—or (b) the result of such a process. I next argue for the immorality of waste. My concluding suggestions are that (W1) if one person needs something for her preservation and a second person has it, is avoidably wasting it, (...) and refuses to allow the first to make some greater use of it, the second may be morally wrong and that (W2) if one person needs something for her preservation understood according to her metric and a second person has it, is avoidably wasting it according to his own metric, and refuses to allow the first to make some greater use of it, the second is morally wrong.

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.

We offer an overview of both the empirical literature on food waste and philosophical work on the concept of waste. We use this background to argue that an overemphasis on the reduction of individual food waste is misleading at best, and pernicious at worst, in combatting the substantial problems that global food waste creates. Rather, we argue that civic engagement and political activism aimed at institutional reform will be essential in addressing these problems.

The issue of poor waste management has become a very important issue of concern to various scholars in environmental studies. Effective waste management in Port Harcourt has been seen as one of the greatest issue being faced in Rivers State. It cannot be over emphasized that the generation of waste and its adverse effect has increased over time. This paper critically looks into the ethical implications and effects of poor waste management in Rivers state with focus (...) on Port Harcourt. Hence, this paper was able to establish that the failure of the government to enact environmental laws and punishing those found wanting, and also providing the necessary working tools for waste managers have all resulted to poor waste management. Thus, the effects of all these cannot be over emphasized. This paper makes some significant recommendations for government, waste managers and the public in general on the necessity to adopt certain ethical principles and also to sensitize the populace on proper waste management. The paper in conclusion exposes some ethical implications and effects of poor waste management in Port Harcourt and how it has resulted to the city of Port Harcourt called the Garden City now being seen as a Tattered City.

Horror film sequels have not received as much serious critical attention as they deserve – this is especially true of the Saw franchise, which has suffered a general dismissal under the derogatory banner ‘Torture Porn’. In this article I use detailed textual analysis of the Saw series to expound how film sequels employ and complicate expected temporal and spatial relations – in particular, I investigate how the Saw sequels tie space and time into their narrative, methodological and moral sensibilities. Far (...) from being a gimmick or a means of ensuring loyalty to the franchise (one has to be familiar with the events of previous episodes to ascertain what is happening), it is my contention that the Saw cycle directly requests that we examine the nature of space and time, in terms of both cinematic technique and our lived, off-screen temporal/spatial orientations. -/- .

Plastic waste accumulation in the environment due to huge volumes of plastic waste produced daily with no effective disposal method and waste management have raised public awareness to look for an alternative to replace the current disposal techniques. Waste utilisation or plastic recycling has been regarded as an excellent method to reduce the abundant amount of plastic waste as well as minimising the environmental impacts. In this article, a total of 163 previous studies between 2012 (...) and 2021 had been reviewed to discuss the utilisation of different types of plastic waste as aggregate in construction materials. This paper evaluates on the use of plastic as aggregate in terms of the physical, mechanical and durability properties of the construction materials as well as the environmental and cost analyses. It was found that the mechanical and durability properties of produced materials were altered after the addition of plastic as aggregates; however, the materials are still fulfilling the requirement of construction materials. Besides, a general SWOT analysis to highlight the advantages and disadvantages of plastic waste utilisation was also conducted. -/- . (shrink)

In this paper we inquire into the fundamental assumptions that underpin the ideal of the Bio-Based Economy as it is currently developed . By interpreting the BBE from the philosophical perspective on economy developed by Georges Bataille, we demonstrate how the BBE is fully premised on a thinking of scarcity. As a result, the BBE exclusively frames economic problems in terms of efficient production, endeavoring to exclude a thinking of abundance and wastefulness. Our hypothesis is that this not only entails (...) a number of internal tensions and inconsistencies with regard to the ideal of BBE, but ultimately undermines the ideal itself, by pushing purported regenerativity into a cataclysmic and terminal discharge. We here point to the strategies that the BBE employs in this exclusion, the fundamental assumptions regarding the relation between energy and economy that underpin this endeavor, as well as to the resulting inconsistencies and their catastrophic consequences. We finally argue for the introduction of the presently excluded question of abundance and wastefulness and explore the implications of such a question for the ideal of a zero-waste humanity.

The environmental concern of plastic waste (PW) generation has escalated to an alarming level due to the versatility and high demand in various applications. In order to search for an effective way to utilise PW, reusing them for the production of construction material appears as an environmentally-friendly approach. This is also because conventional construction materials often consume high energy during production has caused many environmental impacts. This review paper summarises the previous studies on reusing various PW as raw material (...) and aggregate for construction and its properties with special attention to bricks and paving blocks. This paper begins by illustrating on the properties of plastics and the impacts of PW to the environment. Followed by discussion on reusing PW and its impacts on the overall properties of construction material. This review found that limited studies had been conducted on the usage of PW in the production of the paving block. Besides, most of the studies focused predominantly on compressive strength and water absorption as the main parameters to evaluate the characteristics of bricks and paving blocks. It is concluded that the use of PW in construction material could possibly serve as a sustainable source for construction material in the future. (shrink)

John Locke held that every person has a natural duty to use her property efficiently, and that consent is required for legitimate political power. On the face of it, these two positions seem to be in tension. This is because, (1) according to Locke, it is nearly impossible to use resources efficiently unless one lives within a political community, and (2)the waste restriction is enforceable. Consequently, it might seem that persons living outside civil society may be forced to submit (...) to civil power, in violation of the consent requirement. I argue that this tension is only apparent; although the waste restriction is enforceable, the consent requirement is safe. But in the course of resolving this difficulty, three significant, but little-noticed, features of Locke's doctrine of consent to government come to light: (A) consent is conceptually necessary, and not just morally required, for persons to be subject to political power; (B) most people living outside civil society have a moral obligation to enter civil society if they can; and (C) consent to government can bind under duress so long as the duress does not render anyone dependent on the arbitrary wills of others.

Plastic waste is a significant environmental problem for almost all countries; therefore, protecting the environment from the problem is crucial. The most sensible solution to these problems is substituting the natural aggregates with substantial plastic waste in various building materials. This study aimed to optimise the mixed design ratio of cement brick containing plastic waste as aggregate replacement. Plastic cement brick mixtures were prepared by the incorporation of four different types of plastic waste such as polyethylene (...) terephthalate (PET), high-density polyethylene, low-density polyethylene and polypropylene into cement bricks with different cement contents (150, 300 and 450 g) and plastic replacement percentages (0, 3 and 6%). Compressive strength and water absorption of the plastic cement bricks were analysed using a statistical model through the response surface methodology. It revealed the optimum cement brick mixed design is C3-1% PET with the compressive strength of 27.50 MPa and water absorption of 1.16%. The optimised plastic cement brick also satisfied the general ASTM C62-17 requirements for building bricks despite the higher porosity observed by the scanning electron microscopy. The results from Fourier transform infrared spectroscopy analysis also showed that the addition of the plastic waste into cement brick was unlikely to modify the chemical compound within the cement brick mixtures. Thus, the proposed mathematical model can predict the required hardened properties of plastic cement bricks and could lead to greater utilisation of plastic waste in building materials. (shrink)

Within siting literature there is strong agreement that compensation for environmental risks is a necessary condition for local acceptance of waste treatment facilities. In-kind compensation is commonly pushed forward as being more effective than financial benefits in reducing local opposition. By forcusing on the siting of a sanitary landfill in Santiago, Chile, this paper explores the performance of both types of compensation and relates the analysis to the notion of social norms of exchange. These are understood as being based (...) on three main types of social relations: care, justice and freedom. Whereas monetary compensation is associated with market relations based on freedom and the offer of in-kind compensation to egalitarian relations based on justice, the absence of compensation is linked to fraternal relations based on care. It is argued that in-kind compensation is more acceptable than monetary payments or not compensation because people tend to understand siting conflicts more as matters of justice rather than as matters of freedom or care.

E-waste, also known as waste from electrical and electronic equipment, is a solid waste that accumulates quickly due to high demand driven by the market for replacing newer electrical and electronic products. The global e-waste generation is estimated to be between 53.6 million tons, and it is increasing by 3–5% per year. Metals make-up approximately 30% of e-waste, which contains precious elements Au, Ag, Cu, Pt, and other high-value elements, valued at USD 57 billion, which (...) is driving the e-waste recycling industry. It is noteworthy that the recycling of precious elements from e-waste has emerged as a profitable enterprise in several parts of developing nations. E-waste contains 50–100 times higher levels of precious metals compared to natural ores, making it suitable for mining. E-waste recycling in developing nations, mostly occurs through the informal sector comprising manual collection, crushing, segregation and selling of precious elements, such as Au, Ag, Cu, Pb, Pt, and other rare elements (Nd, In, and Ga). The organized sector, on the other hand, mostly employs mechano-chemical methods, such as pyrometallurgy, hydrometallurgy, and bio-hydrometallurgy, which have serious environmental consequences. Both the informal and formal sectors of e-waste processing lead to the leaching of toxic elements into groundwater and soils. Owing to the lesser efficiency of greener technologies, such as phytoremediation and bioremediation, their use in precious metal extraction is very limited. However, this review explores several hyper-accumulating and tolerant plants viz. Brassica juncea and Berkheya coddii, which holds great potential in phytomining of precious metal from e-waste. Thus, the state of the art in precious metal extraction from e-waste as well as the advantages and disadvantages of different metal extraction technologies has been reviewed. (shrink)

Abstract— Polystyrene/waste tires composites were prepared in this study by incorporating shredded waste tires into polydisperse polystyrene in a melt-mixing method. The dynamic mechanical properties of PS and PS/composite have been evaluated and compared. These properties were studied using ARES-Rheometer under nitrogen atmosphere in parallel plate geometry with diameter 8 mm. The measurements are carried out over a wide range of temperatures ranged from 120°C to 220°C and frequencies from 100 to 0.1 radians per second. The shear creep (...) stress J(t) and loss factor were studied and compared with those of unfilled PS. The dynamic mechanical properties and stability at elevated temperatures were found to increase with the addition of waste tires to PS as confirmed by the results. From the results, the value of J(t) modulus for PS/waste tire is higher than this for the original material of PS. The incorporation of the rubber to the PS changes the value of J(t) at 0.001 second from 5.610-6 to 3.710-6 Pa-1 for PS and PS/waste tire, respectively and this difference increases with time. This confirmed that PS/waste tire composite exhibits higher stability at 180°C for a long time than the original unfilled PS. At frequency  = 6.7102 radians/s , the value of tan increases about 20% by the incorporation of the rubber filler, due to the increase in the G'' modulus particularly at low frequencies in the flow regime.

Meritocracy claims to reward the meritorious with more resources, thereby achieving social efficiency and justice in a level playground. This article argues that the rise of meritocracy in a society is the institutional consequence of adopting progressive humanism, an ideal-type worldview that advocates the harmonious co-realization of individual achievement and social contribution. However, meritocracy is a self-defeating illusion because, even in a level playground, it only rewards conspicuous and wasteful display of ‘merit’ rather than genuine contributions to society. Similar to (...) the promise of an afterlife to Catholicism, the illusion of meritocracy constitutes an indispensable theodicy to progressive humanism. For societies holding such worldviews, meritocracy is a necessary illusion that cannot be dispelled by institutional reforms or political movements. (shrink)

The development of nuclear energy technologies in the second half of the 20th century came with great hopes of rebuilding nations recovering from the devasta-tion of the Second World War or recently released from colonial rule. In coun-tries like France, India, the USA, Canada, Russia, and the United Kingdom, nuclear energy became the symbol of development towards a modern and technologically advanced future. However, after more than six decades of experi-ence with nuclear energy production, and in the aftermath of the (...) Fukushima nuclear disaster, it is safe to say that nuclear energy production is not without its problems.Some of these problems have their origins in the very materiality of the technolo-gies involved. For example, not only does the use of highly radioactive materials give rise to risks for the current generation (e.g., in the potential for disaster when reactors melt down) but high-level radioactive waste from nuclear energy production presents a serious intergenerational problem for which an acceptable final solution or its implementation remains elusive. Moreover, nuclear energy technologies have specific social and political consequences. For example, they have been said to be authoritarian technologies (Winner, 1980), requiring cen-tralized authority, secrecy, and technocratic decision-making. While some of these problems could have been foreseen before nuclear energy technologies were introduced, others only arose after these technologies were already integrated into the social and infrastructural fabric of our lives. Addition-ally, new technologies (e.g., Generation III, III+ and IV reactors) are still being developed, bringing with them new and uncertain hazards and risks. Ignorance and uncertainty about the possible deleterious effects of introducing a new technology are inevitable, especially if the technology is complex, large time-scales are involved, or risks depend on social or political factors unforeseen in the design stage. However, this should not deter us from developing and intro-ducing new technologies. Rather, it should motivate us to organize these ‘exper-iments’ with new technologies in society in such a way that we can learn about their possible hazards and risks as effectively and responsibly as possible (van de Poel, 2011, 2015). In this way, it is possible to minimize risks and avoid unwant-ed moral, social or political developments. However, organizing such experi-ments responsibly also means that one could come to the conclusion that continuing an experiment is no longer responsible or desirable. Should we be prepared for such a scenario, and if so, how could we do that? One possible strategy to tackle this issue is that the technology and its introduction should be reversible. The aim of this thesis is to further explore this strategy by answering the following main research question (RQ) and accompanying subquestions (SQ):RQ: What are the implications of reversibility for the responsible develop-ment and implementation of nuclear energy technologies?SQ1: Under what conditions can nuclear energy technologies be considered reversible?SQ2: Why should nuclear energy technologies be reversible?SQ3: If so, how could the reversibility of nuclear energy technologies be achieved?After the introductory chapter 1, the chapters that form the main body of this dissertation each provide a distinct contribution to answering the three subques-tions and, by extension, the main research question. Guided by three historical case studies of nuclear energy technology development (i.e., India, France and the USA), chapter 2 answers the first subquestion by formulating the two condi-tions under which it can be considered reversible, i.e., 1) the ability to stop the further development and deployment of a that technology in society, and 2) the ability to undo the undesirable outcomes (material, institutional or symbolic) of the development and deployment of the technology. Chapter 3 subsequently tackles the second subquestion by establishing the general desirability of technological reversibility by virtue of its relation to responsibility in Emmanuel Levinas’ ethical phenomenology. It argues that technology development is a legitimate response to responsibility but inevitably falls short of the responsibility that inspires it, incessantly calling for technological and political change in the process. Having thus argued that nuclear energy technologies should ideally be reversible, chap-ters 4 and 5 work towards specific strategies to achieve technological reversibil-ity. Chapter 4 first investigates the processes that make it difficult to stop the further development and implementation of a nuclear energy technology in society, thus provid-ing input on how to fulfill the first condition for the reversibility of nuclear energy technologies. To do so, it presents a phenomenological perspective on technology and its adoption based on the work of Alfred Schutz. It also explores different ways in which technology adoption drives the processes of path depend-ence towards technological lock-in. Chapter 5 examines the history of geological disposal of high-level radioactive waste in the USA. It identifies a number of concrete policy pitfalls that could lead to lock-in and that should consequently be avoided. It also presents a number of general design strategies that could facilitate the undoing of undesirable consequences of a technology, thus providing input on how to fulfill the second condition for the reversibility of nuclear energy technol-ogies.Chapter 6 summarizes the central findings of the thesis and explains how these help to answer the research questions. On top of this, it reflects on a number of complications connected to reversibility considerations. Based on this, it is concluded that the question of irreversibility and reversibility is context- and technology-specific and a matter of degree. The chapter concludes with a reflec-tion on generalizations and limitations of the results. Finally, chapter 7 discusses the implications of this dissertation’s results for responsibly experimenting with nuclear energy technologies in society. (shrink)

Because factory-farmed meat production inflicts gratuitous suffering upon animals and wreaks havoc on the environment, there are morally compelling reasons to become vegetarian. Yet industrial plant agriculture causes the death of many field animals, and this leads some to question whether consumers ought to get some of their protein from certain kinds of non factory-farmed meat. Donald Bruckner, for instance, boldly argues that the harm principle implies an obligation to collect and consume roadkill and that strict vegetarianism is thus immoral. (...) But this argument works only if the following claims are true: all humans have access to roadkill, roadkill would go to waste if those who happen upon it don’t themselves consume it, it’s impossible to harvest vegetables without killing animals, the animals who are killed in plant production are all-things-considered harmed by crop farming, and the best arguments for vegetarianism all endorse the harm principle. As I will argue in this paper, each claim is deeply problematic. Consequently, in most cases, humans ought to strictly eat plants and save the roadkill for cats. (shrink)

Numerous agricultural wastes are impractically discarded every day, and one of these is rice bran. This study investigated the production of a biodegradable straw made of cassava starch and powdered rice bran. It aimed to determine the effectiveness of the different treatments of Cassava Starch-Rice Bran in terms of water resistance, tensile strength, and biodegradability. An experimental design was used in conducting the study. There were three treatments made in making CSRB straws: the first, with more rice bran; the second, (...) with the same cassava starch and rice bran ratio; and the third, with more cassava starch. These treatments produced three replicates each. The straws were placed in a dehydrating machine for 24 hours at a temperature of 60° Celsius. The straws were then coated with beeswax after being removed from their respective molders. The CSRB straws were found to be water resistant due to the beeswax coating applied, although it had a weak tensile strength even with the presence of beeswax. The rate of biodegradability of the CSRB straw was fast due to it being made up of organic materials. The results revealed that straws made from Cassava Starch and Powdered Rice Bran are effective in terms of water resistance and biodegradability. (shrink)

I address the question, ‘Should a retributivist support an entrapment defense and if so, under what circumstances?’, by considering the culpability of entrapped defendants. An entrapment defense is invoked by defendants who claim they violated the law because they were enticed to crime by the police and would not otherwise have committed the crime. There are different rationales for the defense: people who are normally law abiding, and who are not predisposed to commit crimes, do not commit crimes merely when (...) the opportunity is presented, without further coaxing—only criminals do—and so spending resources to entice and then punish such “false criminals” is wasteful from a utilitarian perspective. Several theorists assume retributivists must oppose the defense: entrapped defendants have broken the law and, according to one version of retributivism (Mabbott), this itself might warrant punishment; they are still culpable although they were enticed, because succumbing to temptation is no defense—there is no ‘private entrapment defense’; and to not punish the non-predisposed who are enticed to crime by government, while punishing those who are predisposed, is wrongly to assert that a person’s culpability hinges on their predisposition and wrongly to punish someone not for their present conduct but for their character or past actions. I explore some reasons why a retributivist can support an entrapment defense. First, entrapped defendants may be less culpable than the privately enticed insofar as they do not cause harm. As police control the situation, no actual harm is caused, and whether one actually causes harm may bear on one’s culpability; and if one’s predisposition was weak and required substantial police coaxing to be triggered, we might say that the police action and not the defendant caused the crime in the relevant sense. Second, applying Robert Nozick’s account of coercion in a novel way, I consider the argument that entrapped defendants may be less culpable insofar as their action was not fully voluntary, in that unlike in private enticement cases, they necessarily underestimate the probability of being caught before making their choice.

Games may seem like a waste of time, where we struggle under artificial rules for arbitrary goals. The author suggests that the rules and goals of games are not arbitrary at all. They are a way of specifying particular modes of agency. This is what make games a distinctive art form. Game designers designate goals and abilities for the player; they shape the agential skeleton which the player will inhabit during the game. Game designers work in the medium of (...) agency. Game-playing, then, illuminates a distinctive human capacity. We can take on ends temporarily for the sake of the experience of pursuing them. Game play shows that our agency is significantly more modular and more fluid than we might have thought. It also demonstrates our capacity to take on an inverted motivational structure. Sometimes we can take on an end for the sake of the activity of pursuing that end. (shrink)

The public rejection of scientific claims is widely recognized by scientific and governmental institutions to be threatening to modern democratic societies. Intense conflict between science and the public over diverse health and environmental issues have invited speculation by concerned officials regarding both the source of and the solution to the problem of public resistance towards scientific and policy positions on such hot-button issues as global warming, genetically modified crops, environmental toxins, and nuclear waste disposal. The London Royal Society’s influential (...) report “Public Understanding of Science”, which spearheaded the now-thriving area of science... (shrink)

The paper argues that members of future generations have an entitlement to natural resources equal to ours. Therefore, if a currently living individual destroys or degrades natural resources then he must pay compensation to members of future generations. This compensation takes the form of “primary goods” which will be valued by members of future generations as equally useful for promoting the good life as the natural resources they have been deprived of. As a result of this policy, each generation inherits (...) a “Commonwealth” of natural resources plus compensation. It is this inherited “Commonwealth” which members of that generation must then pass on to members of the next generation. Once this picture is accepted, the standard bundle of property rights is problematic, for it takes the owner of a constituent of the Commonwealth to have the right to “waste, destroy or modify” that item at will. This paper therefore presents a revised set of property rights which takes seriously the idea that each generation has an equal claim on the resources that nature has bequeathed us, whilst allowing certain effects on those natural resources by each generation, and a degree of exclusive use of those natural resources owned by an individual.

Background and Objectives: In this research article, the researcher addresses the issue of creating public understanding in a democratic society about the progress of science, with an emphasis on pluralism from philosophers of science. The idea that there is only one truth and that there are just natural laws awaiting discovery by scientists has historically made it difficult to explain scientific progress. This belief motivates science to develop theories that explain the unity of science, and it is thought that diversity (...) in the way different ideas presented by scientists is a problem that results in time being wasted in search of the most accurate theory. Some scientists perceive a benefit in having a range of scientific hypotheses, though. One benefit that is frequently cited is that scientific diversity as a whole contributes to the development of a democratic society that permits the expression of a range of viewpoints. The road to accountable scientific pluralism is fraught with difficulties, though. Therefore, it is crucial to take into account both pluralism's advantages and disadvantages. This research aims at: 1. analyzing in an epistemological way the interpretation of scientific theories and the progress of science from the perspectives of scientific pluralists; 2. analyzing the relationship between science and democracy in explaining scientific significance and progress; and 3. synthesizing new knowledge on epistemic dependentism and to argue that it plays a significant role in evaluating research issues related to scientific pluralism. Methodology: The research methodology involves the application of documentary investigation along with philosophical discourse. The method of philosophical argumentation involves analyzing the lines of arguments found in relevant academic publications in order to assess their validity and soundness. Main Results: One key argument of the pluralists is the use of the concept of theoretical pluralism, which suggests that scientific knowledge is created from a variety of perspectives according to the social and cultural context of knowledge creation. It is found that part of Longino's argument is based on the negation of rational/social dichotomy. Moreover, her theory is a departure from philosopher of science Philip Kitcher, who advocates the creation of scientific knowledge and the evaluation of scientific progress through the means of democratic society. He explains that these procedures will lead to "well-ordered science" in democratic society. Discussions: The researcher examines the underlying ideas accepted by these two philosophers of science and finds that although their opinions differ, they have common ground in the acceptance of consensus. However, the views of both philosophers still lack weight in explaining the knowledge itself. The researcher argues that the acceptance of pluralism as a way of understanding scientific progress necessarily lends itself to dependentism, which points to interdependence in comparisons of superiority/inferiority between scientific theories. It is undeniable that the situation has emerged all the time, even though the success of the scientific theories being compared to each other comes from different social and cultural grounds of thought. Conclusions: Some popular models of scientific pluralism in the philosophy of science still lack a compelling justification, particularly on the epistemic grounds. By elucidating the epistemic significance of the interdependence of these things, scientific pluralism can be strengthened by incorporating the notion of epistemic dependentism into the analysis of scientific progress.

1. Animal Cruelty Industrial farming is appallingly abusive to animals. Pigs. In America, nine-tenths of pregnant sows live in “gestation crates. ” These pens are so small that the animals can barely move. When the sows are first crated, they may flail around, in an attempt to get out. But soon they give up. Crated pigs often show signs of depression: they engage meaningless, repetitive behavior, like chewing the air or biting the bars of the stall. The sows live like (...) this for four months. Gestation crates will be phased out in Europe by the end of 2012, but they will still be used in America.1 In nature, pigs nurse their young for about thirteen weeks. But in industrial farms, piglets are taken from their mothers after about ten days. Because the piglets are weaned prematurely, they develop a lifelong craving to suck and chew. But the farmers don’t want them sucking and chewing on other pigs’ tails. So the growers routinely snip off the tails of all their pigs. They do this with a pair of pliers and no anesthetic. However, the whole tail is not removed; a tender stump remains. The point is to render the area sensitive, so the pigs being chewed on will fight back. Which they do.2 Over 113 million pigs are slaughtered each year in America.3 Typically, these pigs are castrated, their needle teeth are clipped, and one of their ears is notched for identification —all without pain relief.4 In nature, pigs spend up to three quarters of their waking hours foraging and exploring their environment.5 But in the factory farms, “tens of thousands of hogs spend their entire lives ignorant of earth or straw or sunshine, crowded together beneath a metal roof standing on metal slats suspended over a septic tank. ”6 Bored, and in constant pain, the pigs must perpetually inhale the fumes of their own waste. These pigs often get sick, and their ill health is exacerbated by the overcrowding. In 2000, the U.S. Department of Agriculture compared hog farms containing over 10,000 pigs—which is the norm—with farms containing under 2,000 pigs. (shrink)

As Bhaskar (1989:1) argues, we need to take philosophy seriously because it underwrites both what constitutes science and knowledge and which political practices are deemed legitimate. At present, the field of educational research internationally is witnessing a pragmatist trend, whereby practical education research is carried out without reference to ontological and epistemological concerns. For David Reynolds, a leading UK school effectiveness academic, '[p]recisely because we did not waste time on philosophical discussion or on values debates, we made rapid progress' (...) (1998:20). Equally, for Teddlie, '[t]he orientation of many in the US is to do rather than to reflect […] In reality many practitioners are currently interested in what could work at their school […rather…] than in ruminations about social inequalities associated with different socioeconomic classes' (Teddlie and Reynolds 2000:27). The purpose of this chapter is not only to reclaim critical realist social philosophy for educational research, but also to reclaim reality from the positivist and statistical methodology that underpins School Effectiveness Research (SER) and to make clear the difference that realism makes by virtue of its critical explanatory power in unmasking the ideological nature of SER and its adoption by New Labour.

Justification depends on context: even if E on its own justifies H, still it might fail to justify in the context of D. This sort of effect, epistemologists think, is due to defeaters, which undermine or rebut a would-be justifier. I argue that there is another fundamental sort of contextual feature, disqualification, which doesn't involve rebuttal or undercutting, and which cannot be reduced to any notion of screening-off. A disqualifier makes some would-be justifier otiose, as direct testimony sometimes does to (...) distal testimony, and as manifestly decisive evidence might do to gratuitous evidence on the same team. Basing a belief on disqualified evidence, moreover, is distinctively irrational. One is not necessarily irresponsible. Instead one is turning down a free upgrade to a sleeker, stabler basis for one's beliefs. Such an upgrade would prevent wastes of epistemic effort, since someone who bases her belief on a disqualified proposition E will need to remember E and rethink her belief should E ever be defeated. The upgrade might also reduce reliance on unwieldy evidence, if E is relevant only thanks to some labyrinthine argument; and if even ideal agents should doubt their ability to follow such arguments, even they should care about disqualifiers.

The purpose of this chapter is to provide a guide for conducting thought experiments in epistemology effectively. The guide raises several considerations for best practices when using this research method. Several weaknesses in the way thought experiments are conducted are also identified and several suggestions are reviewed for how to improve them. Training in these research techniques promotes more productive scholarship in epistemology, saves time and resources wasted on less efficient approaches, and reduces the risk that researchers are fooling themselves (...) when they use thought experiments in philosophy.

William Paley ( Natural Theology , 1802) developed the argument-from-design. The complex structure of the human eye evinces that it was designed by an intelligent Creator. The argument is based on the irreducible complexity ("relation") of multiple interacting parts, all necessary for function. Paley adduces a wealth of biological examples leading to the same conclusion; his knowledge of the biology of his time was profound and extensive. Charles Darwin’s Origin of Species is an extended argument demonstrating that the "design" of (...) organisms can be explained by natural selection. Moreover, the dysfunctions, defects, waste, and cruelty that prevail in the living world are incompatible with a benevolent and omnipotent Creator. They come about by a process that incorporates chance and necessity, mutation and natural selection. In addition to science, there are other ways of knowing, such as art, literature, philosophy, and religion. Matters of value, meaning, and purpose transcend science. (shrink)

One of the leading exponents of W's ideas on the language games of inner and outer (the `Two Selves' operation of our personality or intentionality or EP etc.) is the prolific Daniel Hutto (DH). His approach is called `Radical Enactivism' and is well explained in numerous recent books and papers (see my review of Radicalizing Enactivism) and a new one is appearing as I write (Evolving Enactivism). It is a development of or version of the Embodied Mind ideas now current (...) and, cleansed of its jargon, it is a straightforward extension of W's 2nd and 3rd period writings (though Hutto seems only intermittently aware of this). -/- Unfortunately, in 2006 Hutto had not yet arrived at his Radical Enactivism, so much time is wasted on McDowell and Brandom and of course none of them to this day have totally digested the later W and his prescient analysis of automatic behavior and the two systems of thought - so fully in tune with contemporary research. Nor is there any discussion of Searle's groundbreaking and completely Wittgensteinian (unwittingly) disquisitions on the Construction of Social Reality. Thus, his chapters 5 and 6 on Realism and Idealism etc., though superb for 2002, need a complete rewrite from a modern two systems viewpoint and I provide a start on that in my review. Much time is wasted on Davidson and Williams, etc. but one can endure them for Hutto's brilliant analyses and the frequent quotes from W. The last chapter gives his critic Rupert Read the counterblast he deserves and permits a slight update to 2006. Overall a lovely book and I eagerly await the third edition which I hope will ensue. -/- Those wishing a comprehensive up to date framework for human behavior from the modern two systems view may consult my book ‘The Logical Structure of Philosophy, Psychology, Mind and Language in Ludwig Wittgenstein and John Searle’ 2nd ed (2019).
