Many defend the thesis that when someone knows p, they couldn’t easily have been wrong about p. But the notion of easy possibility in play is relatively undertheorized. One structural idea in the literature, the principle of Counterfactual Closure (CC), connects easy possibility with counterfactuals: if it easily could have happened that p, and if p were the case, then q would be the case, it follows that it easily could have happened that q. We first argue that while CC (...) is false, there is a true restriction of it to cases involving counterfactual dependence on a coin flip. The failure of CC falsifies a model where the easy possibilities are counterfactually similar to actuality. Next, we show that extant normality models, where the easy possibilities are the sufficiently normal ones, are incompatible with the restricted CC thesis involving coin flips. Next, we develop a new kind of normality theory that can accommodate the restricted version of CC. This new theory introduces a principle of Counterfactual Contamination, which says roughly that any world is fairly abnormal if at that world very abnormal events counterfactually depend on a coin flip. Finally, we explain why coin flips and other related events have a special status. A central take home lesson is that the correct principle in the vicinity of Safety is importantly normality-theoretic rather than (as it is usually conceived) similarity-theoretic. (shrink)

The proper relationship between phenomenology and naturalism has reemerged as a pressing issue following interdisciplinary developments in the cognitive sciences. Most solutions opt for a naturalized phenomenology, rather than a phenomenological naturalism. This article takes up the latter approach, confronting the implications of Merleau-Ponty's reformulation of Husserl's paradox of subjectivity. I argue that Merleau-Ponty's formulation—which I term “the paradox of madness”—reveals a deep, ontological contingency in what Husserl took to be necessary transcendental structures of consciousness and world, revealing that these (...) transcendental structures are in fact embedded in and contaminated by the very world they constitute and disclose.

Three different types of low cost soil amendments, namely, EDTA, elemental S and N-fertilizer, were investigated with Vetiver grass, Vetiveria zizanioides (Linn.) Nash growing under highly mixed Cd–Pb contamination conditions. A significant increase (p < 0.05) in Cd and Pb accumulation were recorded in the shoots of all EDTA and N-fertilizer assisted treatments. The accumulation of Cd in 25 mmol EDTA/kg soil and 300 mmol N/kg soil showed relatively higher translocation factor (1.72 and 2.15) and percentage metal efficacy (63.25 (...) % and 68.22 %), respectively, compared to other treatments. However, it was observed that the increased application of elemental S may inhibit the availability of Pb translocation from soil-to-root and root-to-shoot. The study suggests that viable application of 25 mmol EDTA/kg, 300 mmol N/kg and 20 mmol S/kg soil have the potential to be used for soil amendment with Vetiver grass growing under contaminated mixed Cd–Pb soil conditions.

A wide family of many-valued logics—for instance, those based on the weak Kleene algebra—includes a non-classical truth-value that is ‘contaminating’ in the sense that whenever the value is assigned to a formula φ⁠, any complex formula in which φ appears is assigned that value as well. In such systems, the contaminating value enjoys a wide range of interpretations, suggesting scenarios in which more than one of these interpretations are called for. This calls for an evaluation of systems with multiple contaminating (...) values. In this paper, we consider the countably infinite family of multiple-conclusion consequence relations in which classical logic is enriched with one or more contaminating values whose behavior is determined by a linear ordering between them. We consider some motivations and applications for such systems and provide general characterizations for all consequence relations in this family. Finally, we provide sequent calculi for a pair of four-valued logics including two linearly ordered contaminating values before defining two-sided sequent calculi corresponding to each of the infinite family of many-valued logics studied in this paper.

Over the years, ethylene-diamine-tetra-acetate (EDTA) has been widely used for many purposes. However, there are inadequate phytoassessment studies conducted using EDTA in Vetiver grass. Hence, this study evaluates the phytoassessment (growth performance, accumulation trends, and proficiency of metal uptake) of Vetiver grass, Vetiveria zizanioides (Linn.) Nash in both single and mixed heavy metal (Cd, Pb, Cu, and Zn)—disodium EDTA-enhanced contaminated soil. The plant growth, metal accumulation, and overall efficiency of metal uptake by different plant parts (lower root, upper root, lower (...) tiller, and upper tiller) were thoroughly examined. The relative growth performance, metal tolerance, and phytoassessment of heavy metal in roots and tillers of Vetiver grass were examined. Metals in plants were measured using the flame atomic absorption spectrometry (F-AAS) after acid digestion. The root-tiller (R/T) ratio, biological concentration factor (BCF), biological accumulation coefficient (BAC), tolerance index (TI), translocation factor (TF), and metal uptake efficacy were used to estimate the potential of metal accumulation and translocation in Vetiver grass. All accumulation of heavy metals were significantly higher (p < 0.05) in both lower and upper roots and tillers of Vetiver grass for Cd + Pb + Cu + Zn + EDTA treatments as compared with the control. The single Zn + EDTA treatment accumulated the highest overall total amount of Zn (8068 ± 407 mg/kg) while the highest accumulation for Cu (1977 ± 293 mg/kg) and Pb (1096 ± 75 mg/kg) were recorded in the mixed Cd + Pb + Cu + Zn + EDTA treatment, respectively. Generally, the overall heavy metal accumulation trends of Vetiver grass were in the order of Zn >>> Cu > Pb >> Cd for all treatments. Furthermore, both upper roots and tillers of Vetiver grass recorded high tendency of accumulation for appreciably greater amounts of all heavy metals, regardless of single and/or mixed metal treatments. Thus, Vetiver grass can be recommended as a potential phytoextractor for all types of heavy metals, whereby its tillers will act as the sink for heavy metal accumulation in the presence of EDTA for all treatments.

Logics based on weak Kleene algebra (WKA) and related structures have been recently proposed as a tool for reasoning about flaws in computer programs. The key element of this proposal is the presence, in WKA and related structures, of a non-classical truth-value that is “contaminating” in the sense that whenever the value is assigned to a formula ϕ, any complex formula in which ϕ appears is assigned that value as well. Under such interpretations, the contaminating states represent occurrences of a (...) flaw. However, since different programs and machines can interact with (or be nested into) one another, we need to account for different kind of errors, and this calls for an evaluation of systems with multiple contaminating values. In this paper, we make steps toward these evaluation systems by considering two logics, HYB1 and HYB2, whose semantic interpretations account for two contaminating values beside classical values 0 and 1. In particular, we provide two main formal contributions. First, we give a characterization of their relations of (multiple-conclusion) logical consequence—that is, necessary and sufficient conditions for a set Δ of formulas to logically follow from a set Γ of formulas in HYB1 or HYB2 . Second, we provide sound and complete sequent calculi for the two logics. (shrink)

This article interrogates a certain philosophical scene – one which constitutes itself through the position of what Jacques Derrida calls “the ethical instance of violence.” This scene supposes a certain “style” of writing or doing philosophy, and perhaps even a certain philosophical “genre” or “subgenre”: the philosophical discourse on violence. In the course of the essay, I analyze this quasi-juridical scene through readings of Aristotle, Walter Benjamin, Giorgio Agamben, Judith Butler, Slavoj Žižek, Werner Hamacher, Rodolphe Gasché, and Martin Hägglund among (...) others. The scene, built on texts on texts on violence, demands a logic of purity; it is wary of contaminations and equivocations. And yet it thrives on them. In analyzing the implications of text, writing, and trace for the philosophical discourse on violence, I follow Derrida “just to see” what could make the scene tremble. (shrink)

This study used a flame atomic absorption spectrometer (FAAS) and atomic fluorescence spec-trophotometer (AFS) to detect the concentrations of chromium (Cr), cadmium (Cd), lead (Pb), hy-drargyrum (Hg) and arsenic (As) in soils and three genotypes of vegetables in greenhouse, as well as analyzed the physical and chemical properties of soils, including soil pH, soil organic matter (OM), basic nutrients, electrical conductivity (EC) and cation exchange capacity (CEC) in Guan- zhong areas, Shaanxi province, China. The results showed that comparing to subsoil, (...) the sampled topsoil is enriched in Cr, Cd, Pb, As and Hg. Cd (0.83 - 3.17 mg·kg-1) and Hg (0.40 - 1.44 mg·kg-1) are exceeding the limited value stated in “the 2006 Greenhouse Vegetable Producing Environmental Quality Evaluation Standards” of 0.40 mg·kg-1 and 0.35 mg·kg-1 respectively. However, Nanzhuang greenhouse soil is within the limits. The heavy metal pollution index (HPI) of soil in Sanyuan (8.10) is the highest and in Dongzhang (4.23) is the lowest. The contents of Pb (0.201 - 0.376 mg·kg-1) were exceeding the limited value (0.20 mg·kg-1) in vegetables species, and Cd (0.0363 - 0.0572 mg·kg-1) in some place were also exceeding the limited value (0.05 mg·kg-1). Greenhouse soils were becoming acidified year after year; the ratios of N, P and K in soil were seriously imbalanced. According to the impacting factors, OM, pH, available P, EC and CEC have obviously effected the accumulation of Cr and Hg. However, there was not enough evidence for the effects of available nitrogen and available potassium. (shrink)

Abstract: Global chemical contamination is an underexplored source of global catastrophic risks that is estimated to have low a priori probability. However, events such as pollinating insects’ population decline and lowering of the human male sperm count hint at some toxic exposure accumulation and thus could be a global catastrophic risk event if not prevented by future medical advances. We identified several potentially dangerous sources of the global chemical contamination, which may happen now or could happen in the (...) future: autocatalytic reactions, exposure to multiple subthreshold sources, and long-term unintended consequences, arising from both natural and bioengineered sources. We list several especially dangerous chemicals—dioxin, organiс compounds, and toxic heavy metals. We also discuss the features of such dangerous chemicals—molecules that can stay in the biosphere for a long time and affect it over time. We explore several social processes and scenarios where global chemical contamination becomes possible: large natural catastrophe like meteorite impact, supervolcano eruption, new ways of predicting properties of the chemicals via machine learning and their manufacturing via synthetic biology, uncontrolled “capitalistic” economic development with a corresponding large waste production, quick adoption of many chemicals with unknown long-term properties and unintended side-effects. These are all low probability, so work on other global catastrophic risks should be prioritized, but chemical risks could exacerbate other types of catastrophe contributing to social collapse.

In this article, an account of the architecture of the cognitive contamination system is offered, according to which the contamination system can generate contamination represen- tations in circumstances that do not satisfy the norms of contamination, including in cases of mere visual contact with disgusting objects. It is argued that this architecture is important for explaining the content, logic, distribution, and persistence of maternal impression beliefs – according to which fetal defects are caused by the pregnant (...) mother’s experiences and actions – which in turn provide important evidence of the architecture of the cognitive contamination system.

The growth response, metal tolerance and phytoaccumulation properties of water spinach (Ipomoea aquatica) and okra (Abelmoschus esculentus) were assessed under different contaminated spiked metals: control, 50 mg Pb/kg soil, 50 mg Zn/kg soil and 50 mg Cu/kg soil. The availability of Pb, Zn and Cu metals in both soil and plants were detected using flame atomic absorption spectrometry. The concentration and accumulation of heavy metals from soil to roots and shoots (edible parts) were evaluated in terms of translocation factor, accumulation (...) factor and tolerance index. Okra recorded the highest accumulation of Pb (80.20 mg/kg) in its root followed by Zn in roots (35.70 mg/kg) and shoots (34.80 mg/kg) of water spinach, respectively. Different accumulation trends were observed with, Pb > Zn > Cu in okra and Zn > Pb > Cu in water spinach. Significant differences (p < 0.01) of Pb, Zn and Cu accumulation were found in both water spinach and okra cultivated among tested treatments. However, only the accumulation of Pb metal in the shoots of water spinach and okra exceeded the maximum permissible levels of the national Malaysian Food Act 1983 and Food Regulations 1985 ([2006]) as well as the international Codex Alimentarius Commission limits. This study has shown that both water spinach and okra have good potential as Pb and Zn phytoremediators. (shrink)

Sources of soil contamination can exist in various types of conditions including in the form of semifluids. In this study, 3 different types of tropical plants, Acacia (Acacia mangium Willd), Mucuna (Mucuna bracteata DC. ex Kurz) and Vetiver (Vetiveria zizanioides L. Nash), were tested under different levels of soil-leachate conditions. The relative growth rate, metal tolerance, and phytoassessment of cadmium (Cd) and lead (Pb) accumulation in the roots and shoots were determined using flame atomic absorption spectrometry. Tolerance index, translocation (...) factor, metal accumulation ratio, and percentage metal efficacy were applied to assess the metal translocation ability among all the 3 types of plants. Significantly higher (P < .05) accumulation of Cd and Pb was exhibited in the roots and shoots of all 3 plants growing under the soil-leachate conditions. However, negative growth performance and plant withering were observed in both Acacia and Mucuna with increased application of higher soil-leachate levels. Vetiver accumulated remarkably higher total concentration of Cd (116.16-141.51 mg/kg) and Pb (156.37-365.27 mg/kg) compared with both Acacia and Mucuna. The overall accumulation trend of Cd and Pb in the 3 plants growing under the soil-leachate conditions was in the order of Vetiver > Acacia > Mucuna. The findings of the study suggest that Vetiver has great potential as Cd and Pb phytoremediator in soil-leachate conditions. (shrink)

We use Bayesian tools to assess Law’s skeptical argument against the historicity of Jesus. We clarify and endorse his sub-argument for the conclusion that there is good reason to be skeptical about the miracle claims of the New Testament. However, we dispute Law’s contamination principle that he claims entails that we should be skeptical about the existence of Jesus. There are problems with Law’s defense of his principle, and we show, more importantly, that it is not supported by Bayesian (...) considerations. Finally, we show that Law’s principle is false in the specific case of Jesus and thereby show, contrary to the main conclusion of Law’s argument, that biblical historians are entitled to remain confident that Jesus existed.

Various types of plant species have been extensively used for heavy metals phyto-remediation without taking into consideration its tolerance threshold. In this study, Vetiver grass, Vetiveria zizanioides (Linn.) Nash was evaluated under five different sets of contaminated spiked cadmium (5Cd, 10Cd, 50Cd, 100Cd and 150Cd mg/kg) and lead (50Pb, 100Pb, 200Pb, 400Pb and 800Pb mg/kg) concentration levels in soil. The growth performance, metal tolerance and phyto-assessment of Cd and Pb in the roots and tillers were assessed using flame atomic absorption (...) spectrometry (FAAS). Tolerance index (TI), translocation factor (TF), biological transfer factor (BTF), biological accumulation coefficient (BAC) and metal uptake efficacy were used to determine the Cd and Pb translocation capability in Vetiver grass. Significantly higher (p<0.05) accumulation of Cd and Pb was recorded in the roots of all spiked treatments. Furthermore, strong and significantly positive correlations were exhibited between the increased levels of spiked heavy metal concentrations with both Cd (r=0.975) and Pb (r=0.952) accumulations. The results of this study showed Vetiver grass as an effective phyto-stabilizer for both Cd and Pb. Nevertheless, the growth of Vetiver grass was restricted when the tolerance threshold of 100 mg/kg (dry weight basis) Cd was exceeded in the contaminated soil. (shrink)

Starting from the importance of the figure of the parrhesiastes—the political and therapeutic truth-teller—for Foucault’s understanding of the care of the self, this paper traces the political figuration of the analogy between philosophers and physicians on the one hand, and rhetors and disease on the other in Plato’s Gorgias. I show how rhetoric, in the form of ventriloquism, infects the text itself, and then ask how we account for the effect of the “contaminated” philosophical dialogue on our readerly health. Is (...) the text placebo, vaccine, or virus? All of these options, I argue, complicate Foucault’s prescription for parrhesia, requiring us to think anew the continuing political ramifications of the metaphor of care. (shrink)

The impact of crude oil on the permeability of the soil in a non oil producing community in Enugu State was investigated using disturbed A 6 CL soil sample collected from Ibagwa Nike area of the state. The sample was divided into five 5 portions and each of the four 4 portions was dosed with Bonny light crude oil at 2 , 4 , 6 and 8 by weight of the samples. The physical properties of the uncontaminated soil were tested (...) and analyses and used as control. The aim of the laboratory investigation was to determine the effects of crude oil on the permeability of the soil. The permeability of the uncontaminated soil was found to be 1.2609x10 7. Permeability tests were also conducted on the contaminated soil samples at the various percentage contaminations. The results showed that at 2 crude oil contamination the permeability was 9.6403x10 9, a drastic reduction. The other results were 6.9600x10 6, 2.2621x10 8 and 9.1286x10 8 at 4 , 6 , and 8 contamination levels, respectively. The ranking after contamination is seen to drop within the range of 10 8 and 10 9 showing a change in the permeability due to oil content. This observed reduction in permeability alters the natural groundwater recharge which can be remedied by enhanced bioremediation through aeration of the soil. Iloeje A. F. | Aniago V.

Does musical contagion elicit garden variety emotions, such as sadness, joy, and anxiety? Does music contaminate us by simply moving us? (...) Which role does imagination play in our affective responses to music? Is musical arousal elicited by automatic mimicry? What does musical contagion teach us about emotions? Musical contagion addresses fundamental theoretical and practical issues. (shrink)

Graham Greene's novels are often read with no reference to his Roman Catholic Faith. Particularly, in India there is little knowledge among both students and scholars about the primacy and the nature of the Roman Catholic Faith. They miss the point that the Roman Faith is a deeply Mysterious Faith. The term "Mystery" is used here in the Catholic sense of that Faith's 'Mysteries'. The essay and the long endnotes try to rectify the errors which creep in when Greene is (...) decontextualized from his Faith by logical positivists. In the name of the 'death of the author' religious relativists contaminated with the heresies of modernism misinterpret Greene. 'Heresies of Modernism' will be alien to those whose academic limits do not go beyond staid woke-seminars. -/- The essay is discursive in nature, but on purpose. It sees Greene's works through the lens of the Suffering Servant and Paul's Hymn to Love. It has to be kept in mind that Greene is a Roman Catholic writer who knew his Church's teachings well. Christianity is not a homogenous term. "Religious" in the essay often means those who are lead consecrated lives within the Catholic Church as distinct from diocesan clergy. (shrink)

Moral error theory of the kind defended by J. L. Mackie and Richard Joyce is premised on two claims: (1) that moral judgements essentially presuppose that moral value has absolute authority, and (2) that this presupposition is false, because nothing has absolute authority. This paper accepts (2) but rejects (1). It is argued first that (1) is not the best explanation of the evidence from moral practice, and second that even if it were, the error theory would still be mistaken, (...) because the assumption does not contaminate the meaning or truth-conditions of moral claims. These are determined by the essential application conditions for moral concepts, which are relational rather than absolute. An analogy is drawn between moral judgements and motion judgements.

This study determined undergraduates’ satisfaction of online food and beverage services amidst financial distress in Nnewi urban, Anambra State, Nigeria. Descriptive survey research design was used by the study. Population consisted of 3,509 students. Sample size was 35. Questionnaire was the instrument used for data collection. Data was analyzed using mean and standard deviation. Findings revealed that different types of food and beverage products were purchased online. The problems undergraduates face in online food and beverage services included delayed delivery, use (...) of artificial food colouring and fear of food contamination. Strategies for enhancing students’ satisfaction of online purchases included timely delivery of products ordered and appropriate delivery mechanism. Findings also showed that the ways online food and beverage purchases can influence undergraduate’s finances included high cost of online food products, additional cost for delivery among others. Among recommendations made was that online food vendors should ensure that food products delivered are same with products ordered by customers in order to enhance customer satisfaction. (shrink)

Kant scholars have paid relatively little attention to his raciology. They assume that his racism, as personal prejudice, can be disentangled from his core philosophy. They also assume that racism contradicts his moral theory. In this book, philosopher Huaping Lu-Adler challenges both assumptions. She shows how Kant's raciology--divided into racialism and racism--is integral to his philosophical system. She also rejects the individualistic approach to Kant and racism. Instead, she uses the notion of racism as ideological formation to demonstrate how Kant, (...) from his social location both as a prominent scholar and as a lifelong educator, participated in the formation of modern racist ideology. As a scholar, Kant developed a ground-breaking scientific theory of race from the standpoint of a philosophical investigator of nature or Naturforscher. As an educator, he transmitted denigrating depictions of the racialized others and imbued those descriptions with normative relevance. In both roles, he left behind, as one of his legacies, a worldview that excluded non-whites from such goods as recognitional respect and candidacy for cultural and moral achievements. Scholars who research and teach Kant's philosophy therefore have an unshakable burden to take part in the ongoing antiracist struggles, through their teaching practices as well as their scholarship. And they must do so with a pragmatic attention to nonideal social realities and a deliberate orientation toward substantial racial justice, equality, and inclusion. Lu-Adler pushes the discourse about Kant and racism well beyond the old debates about whether he was racist or whether his racism contaminates his philosophy. By foregrounding the lasting legacies of Kant's raciology, her work calls for a profound reorientation of Kant scholarship. (shrink)

This paper develops a “Cliffordian” argument for a common epistemic norm governing belief, action, and assertion. The idea is that beliefs are the sorts of things that lead to actions and assertions. What each of us believes influences what we act on and assert, and in turn influences what those around us believe, act on, and assert. Belief, action, and assertion should be held to a common epistemic norm because, otherwise, this system will become contaminated. The paper finishes by drawing (...) out the relativistic implications of the Cliffordian argument. (shrink)

I offer the first sustained defence of the claim that ugliness is constituted by the disposition to disgust. I advance three main lines of argument in support of this thesis. First, ugliness and disgustingness tend to lie in the same kinds of things and properties (the argument from ostensions). Second, the thesis is better placed than all existing accounts to accommodate the following facts: ugliness is narrowly and systematically distributed in a heterogenous set of things, ugliness is sometimes enjoyed, and (...) ugliness sits opposed to beauty across a neutral midpoint (the argument from proposed intensions). And third, ugliness and disgustingness function in the same way in both giving rise to representations of contamination (the argument from the law of contagion). In making these arguments, I show why prominent objections to the thesis do not succeed, cast light on some of the artistic functions of ugliness, and, in addition, demonstrate why a dispositional account of disgustingness is correct, and present a novel problem for warrant-based accounts of disgustingness (the ‘too many reasons’ problem).

The quality of our public discourse – think of the climate change debate for instance – is never very high. A day spent observing it reveals a litany of misrepresentation and error, argumentative fallacy, and a general lack of good will. In this paper I focus on a microcosmic aspect of these practices: the use of two types of argument – the argumentum ad hominem and appeal to authority – and a way in which they are related. Public debate is (...) so contaminated by the misuse of the ad hominem tactic that it is important to have an understanding of one of the ways in which its use may be legitimate. So readers who might have expected an analysis of the ad hominem fallacy will, on the contrary, be presented with an account of one of the places for its potential success. In ad hominem, arguers are viewed as legitimate constitutive targets for their own argument; in authority arguments, arguers provide a legitimate constitutive warrant for an argument they deploy. These types of argument are connected in so far as the identities of persons deploying them carry the cognitive weight of the argument. If authority arguments sometimes deserve to succeed, ad hominem attacks on them are potentially legitimate. An important motivation for this analysis is that in identifying the success conditions for one of the ad hominem types we attain some clarity in the evaluation of their use. (shrink)

The idea that women qua women can be dehumanized has been dismissed by feminist philosophers, like Kate Manne, and by philosophers of dehumanization, like David Livingstone Smith. Against these skeptics, I argue that we can and should use dehumanization to explain an important strand of misogyny. When they are dehumanized, women are represented simultaneously as human and as inhuman embodiments of the natural world. They therefore appear as magical, contaminating, sexualized threats towards whom violence is acceptable or even necessary. Misogynistic (...) dehumanization is important to understanding atrocities like the early modern European witch-hunts, but also contemporary phenomena like incel violence. (shrink)

Modal Meinongianism is a form of Meinongianism whose main supporters are Graham Priest and Francesco Berto. The main idea of modal Meinongianism is to restrict the logical deviance of Meinongian non-existent objects to impossible worlds and thus prevent it from “contaminating” the actual world: the round square is round and not round, but not in the actual world, only in an impossible world. In the actual world, supposedly, no contradiction is true. I will show that Priest’s semantics, as originally formulated (...) in Towards Non-being, tell us something different. According to certain models, there are true contradictions in the actual world. Berto and Priest have noticed this unexpected consequence and have suggested a solution, but I will show that their solution is highly questionable. In the last section of this paper, I will introduce a new and simpler version of modal Meinongianism that avoids the problem. (shrink)

In his late fragment, ‘Sources of Knowledge of Mathematics and Natural Sciences’ Frege laments the tendency to confuse functions with objects and says, ‘It is here that the tendency of language by its use of the definite article to stamp as an object what is a function and hence a non-object, proves itself to be the source of inaccurate and misleading expressions and also of errors of thought. Probably most of the impurities that contaminate the logical source of knowledge have (...) their origins in this.’ This paper applies Frege’s logical insights to a series of influential modal arguments for the existence of souls or minds, in order to demonstrate that they hinge on the error of treating functions as objects. Related arguments have also resulted in the claim that identity statements are necessary, and that apparent identities ‘really’ involve relations of constitution. Here it is argued that once we recognise that all these arguments involve the assimilation of objects and concepts (which Frege identifies with functions) they can be seen to be defective. (shrink)

Environmental health research produces scientific knowledge about environmental hazards crucial for public health and environmental justice movements that seek to prevent or reduce exposure to these hazards. The environment in environmental health research is conceptualized as the range of possible social, biological, chemical, and/or physical hazards or risks to human health, some of which merit study due to factors such as their probability and severity, the feasibility of their remediation, and injustice in their distribution. This paper explores the ethics of (...) identifying the relevant environment for environmental health research, as judgments involved in defining an environmental hazard or risk, judgments of that hazard or risk's probability, severity, and/ or injustice, as well as the feasibility of its remediation, all ought to appeal to non-epistemic as well as epistemic values. I illustrate by discussing the case of environmental lead, a housing-related hazard that remains unjustly distributed by race and class and is particularly dangerous to children. Examining a controversy in environmental health research ethics where researchers tested multiple levels of lead abatement in lead-contaminated households, I argue that the broader perspective on the ethics of environmental health research provided in the first part of this paper may have helped prevent this controversy.

Simon Blackburn, in Truth A Guide for the Perplexed (Blackburn 2006), deploys the relation of thought with the facts and says, ‘We met the argument that theorizing involves an impossible activity of stepping outside our own skins and pretending to a ‘transcendental’ point of view, a standpoint from which we can survey the relationship between our thoughts and facts, without using the very forms of thought whose relation to the facts we are hoping to describe.’ (Blackburn, 2006, 109). My philosophical (...) reflections on this claim appreciate the view and turn towards the epistemic semblance in the metaphysical purview. A few challenges of the theory take up a side-effect of the ‘knowing procedures’ and its subsequent notion of the rigid concomitance of realism without a human face. My endeavor would be to slightly bypass the account of objective realism and debut into the sphere of the old-fashioned query, ‘what do we know about the conceptualized world where concepts steadily contaminate objects?’ We may appreciative beliefs and concepts, which are human creations, as these impart to the human-experienced world where concepts are the objective features of the subject’s conceptual scheme.

The accumulation of potentially toxic elements (PTEs) has raised public awareness due to harmful contamination to both human and marine creatures. This study was designed to determine the concentration of copper (Cu), zinc (Zn), cadmium (Cd), and nickel (Ni) in the intestine, kidney, muscle, gill, and liver tissues of local commercial edible fish, fourfinger threadfin (Eleutheronema tetradactylum), and black pomfret (Parastromateus niger) collected from Morib (M) and Kuala Selangor (KS). Among the studied PTEs, Cu and Zn were essential elements (...) to regulate body metabolism with certain dosages required while Cd and Ni were considered as non-essential elements that posed chronic and carcinogenic risk. The concentration of PTEs in fish tissue samples was analyzed using flame atomic absorption spectrometry (F-AAS). By comparing the concentration of PTEs in fish tissues as a bioindicator, the environmental risk of Morib was more serious than Kuala Selangor because both fish species collected from Morib resulted in a higher PTEs concentration. For an average 62 kg adult with a fish ingestion rate (FIR) of 0.16 kg/person/day in Malaysia, the estimated weekly intake (EWI) of Cd from the consumption of E. tetradactylum (M: 0.0135 mg/kg; KS: 0.0134 mg/kg) and P. niger (M: 0.0140 mg/kg; KS: 0.0132 mg/kg) had exceeded the provisional tolerable weekly intake (Cd: 0.007 mg/kg) established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) and oral reference dose (ORD) values of Cd (0.001 mg/kg/day) as provided by the United States Environmental Protection Agency (USEPA) regional screening level, thus it posed chronic risks for daily basis consumption. Besides, the value of the carcinogenic risk of Cd (0.7−3 to 0.8−3) and Ni (0.5−3 to 0.6−3) were in between the acceptable range (10−6 to 10−4) of the health index that indicates a relatively low possibility cancer occurrence to the consumers in both Morib and Kuala Selangor. This study recommended FIR to be 0.80 kg/person/day to reduce the possibility of posing chronic and carcinogenic risks while at the same time obtaining the essential nutrients from the fish.

Planetary protection is not just a matter of science. It is also a matter of value. This is so independently of whether we only include the protection of science or if we also include other goals. Excluding other values than the protection of science is thus a value statement, not a scientific statement and it does not make planetary protection value neutral. It just makes the axiological basis (that is, the value basis) for planetary protection more limited in a way (...) that is inconsistent with the axiological grounds for back contamination, ethically questionable and strategically unwise. However we look at it, we cannot get away from the conclusion that the axiological dimension of planetary protection is a task that needs to involve experts on value theory as well as experts from a range of different sciences and also include opinions from outside the academic community.

I offer a new argument for the elimination of ‘beliefs’ from cognitive science based on Wimsatt’s concept of robustness and a related concept of fragility. Theoretical entities are robust if multiple independent means of measurement produce invariant results in detecting them. Theoretical entities are fragile when multiple independent means of detecting them produce highly variant results. I argue that sufficiently fragile theoretical entities do not exist. Recent studies in psychology show radical variance between what self-report and non-verbal behaviour indicate about (...) participants’ beliefs. This is evidence that ‘belief’ is fragile, and is thus a strong candidate for elimination. 1 Introduction2 Robustness and Fragility2.1 A historical example of robustness2.2 Fragility and elimination3 The Received View4 Evidence for the Fragility of Belief4.1 Contamination and fragility4.2 Implicit association tests and fragility5 Attempts to Preserve the Belief Category for Cognitive Science5.1 Beliefs and aliefs5.2 Contradictory beliefs5.3 In-between beliefs and the unity assumption5.4 Belief sub-classes5.5 Self-deception6 Alternative Mental States7 Conclusion.

The teikei movement is a Japanese version of the alternative food movement, which emerged around the late 1960s and early 1970s. Similar to now well-known Community Supported Agriculture, it is a farmer-consumer partnership that involves direct exchanges of organic foods. It also aims to build a community that coexists with the natural environment through mutually supportive relationships between farmers and consumers. This article examined the history of the teikei movement. The movement began as a reaction to negative impacts of mechanized (...) and chemically intensive agriculture promoted by the Japanese government. The movement experienced a rapid expansion in the early 1980s, and then gradually declined thereafter. The organic market expansion and certification system intersected with both cultural and gender role changes, impacting the teikei movement negatively. Consequently, the membership of teikei consumer groups has shrunk. Furthermore, the March 2011 Fukushima Daiichi nuclear power plant accident caused unprece dented damage to organic farmers in the affected regions. Despite the scientific uncertain about the safety level of radiation exposure, the organic farmers and the teikei consumer groups managed the situation and found a way to inspect radiation contamination. They did so with the support by networking with other teikei-related actors. This response to the nuclear power plant accident suggests that although the level of embeddedness presumably varies among teikei actors, ethics guided by the teikei principles are effective in forging a resilient partnership between farmers and consumers and in keeping the teikei system alive as an agent for social change.

Music can infect us. In the dominant approach, music contaminates listeners through emotional mimicry and independently of value appraisal, just like when we catch other people’s feelings. Musical contagion is thus considered fatal to the mainstream view of emotions as cognitive evaluations. This paper criticizes this line of argument and proposes a new cognitivist account: the value metaphor view. Non-cognitivism relies on a contentious model of emotion transmission. In the competing model (social appraisal), we catch people’s emotions by appraising value (...) through their emotional expressions. Social appraisal debunks the main motivation for non-cognitivism and offers fruitful insights into musical contagion. Combining it with metaphor theory, I claim that musical contagion involves experiencing the music as a metaphor for emotions and values. Just like people infect us as we appraise value through their emotional expressions, music contaminates listeners because they hear it metaphorically-as some emotional expression and hereby appraise it metaphorically-as some value. As infectious music “sounds like” emotions and values, cognitivism is safe. (shrink)

This chapter articulates two concerns that Karl Jaspers raised (with Hannah Arendt) about the common practice of viewing moral evil as unintelligible. The first is that this involves exoticizing the act and/or perpetrator in such a way that moral condemnation becomes difficult. The second is that it can lead us to treat the perpetrator, place, or victim as tainted or stained by a force whose motives we cannot grasp; this in turn can lead to magical thinking about evil as somehow (...) contagious or contaminating. After distinguishing some of the main categories of evil discussed in the western tradition, I examine ways in which moral evil, in particular, has been characterized as unintelligible, and try to discern which of them raises these Jaspersian concerns. I argue that there are at least two conceptions of “radical evil”—not the Kantian one, but the ones articulated by Hannah Arendt—that do so. (shrink)

Reading different or controversial intentions into Marx and Engels’ works has been a common but somewhat unquestioned practice in the history of Marxist scholarship. Engels’ Dialectics of Nature, a torso for some and a great book for others, is a case in point. The entire Engels debate separates into two opposite views: Engels the contaminator of Marx’s “new materialism” vs. Engels the self-educated genius of dialectical materialism. What Engels, unlike Marx, has not enjoyed so far is a critical reading that (...) considers the relationship between different layers of this standard text: authorial, textual, editorial, and interpretational. Informed by a historical hermeneutic, this book questions the elements that structure the debate on the Dialectics of Nature. It analyzes different political and philosophical functions attached to Engels’ text, and relocates the meaning of the term “dialectics” into a more precise context. Arguing that Engels’ dialectics is less complete than we usually think it is but that he achieved more than most scholars would like to admit, this book fully documents and critically analyzes Engels’ intentions and concerns in the Dialectics of Nature, the process of writing, and its reception and edition history in order to reconstruct the solved and unsolved philosophical problems in this unfinished work.

Michael Marder in Dump Philosophy claims that that there has been so much dumping with modern civilization that we now live in a dump, with those parts of our environment not contaminated by dumping, now rare. The growth of the dump is portrayed as the triumph of nihilism, predicted by Nietzsche as the outcome of life denying Neoplatonist metaphysics. Marder’s proposed solution, characterized as “undumping”, is to accept the dump and to promote reinterpretations and informal communities within the dump. It (...) is argued here that Marder provides great insight into our current situation and its causes; however, his proposed solution is too weak. To respond to the situation described, it is argued, it is necessary to distinguish between healthy and unhealthy dumping, or more broadly, healthy and unhealthy participation in nature. To make this distinction, it is necessary see humans as ecosystems and components of ecosystems, including the global ecosystem, as these have been characterized by anti-reductionist ecologists. Ecosystems can be healthy or unhealthy. Dumping and dumps should be identified as problematic outputs when they damage the health of ecosystems. The products of human activity not destined to be consumed or used for further productive activity, can then be identified and judged according to whether they augment or damage ecosystems’ health. Dumping should be severely restricted. This should be associated with making a commitment to life and its value, and living to augment life, developing the social and economic forms and institutions that facilitate living in this way.

A high standard of planetary protection is important for astrobiology, though the risk for contamination can never be zero. It is therefore important to find a balance. If extraterrestrial life has a moral standing in its own right, it will also affect what we have to do to protect it. The questions of how far we need to go to protect extraterrestrial life will be even more acute and complicated when the time comes to use habitable worlds for commercial (...) purposes. There will also be conflicts between those who want to set a world aside for more research and those who want to give the green light for development. I believe it is important to be proactive in relation to these issues. The aim of my project is therefore to identify, elucidate, and if possible, suggest solutions to potential conflicts between astrobiology, planetary protection, and commercial use of space. (shrink)

In his The Meaning of Disgust, Colin McGinn employs elements of the phenomenological theory of disgust advanced by Aurel Kolnai in 1929. Kolnai’s treatment of what he calls “material” disgust and of its primary elicitors—putrefying organic matter, bodily wastes and secretions, sticky contaminants, vermin—anticipates more recent scientific treatments of this emotion as a mode of protective recoil. While Nina Strohminger charges McGinn with neglecting such scientific studies, we here attempt to show how Kolnai goes beyond experimental findings in his careful (...) description of the phenomenological differences between disgust and other emotions of forceful disapproval.

Badiou claims Deleuze’s thinking is pre-critical metaphysics that cannot be understood in relation to Kant. I argue that Deleuze is indeed a metaphysical thinker, but precisely because he is a kind of Kantian. Badiou is right that Deleuze rejects the overwhelmingly epistemic problematics of critical thought in its classical sense, but he is wrong to claim that Deleuze completely rejects Kant. Instead, Deleuze is interested in developing a metaphysics that prolongs Kant’s conception of a productive synthesis irreducible to empirical causation. (...) Where Badiou’s criticism might tell however is in the risk that Deleuze’s strategy runs of contaminating his new metaphysics with a new kind of transcendental idealism. This reading has recently been developed by Ray Brassier and I explore and evaluate it, concluding that in Difference and Repetition this accusation may be correct, but that by the time of Anti-Œdipus, Deleuze (now with Guattari) has the intellectual resources to resist it.

All the biotic and abiotic factors that act on an organism, population, or ecological community and influence its survival and development constitute its environment. Biotic factors include the organisms themselves, their food, and their interactions. Abiotic factors include such items as sunlight, soil, air, water, climate, and pollution. Organisms respond to changes in their environment by evolutionary adaptations in form and behaviour. At present humanity is facing great challenges for its survival as both these factors have come under great stress (...) due to its unbridled demands of national economic growth and individual needs and desires. Grave Crisis: On the abiotic front, a grave ecological crisis is caused by man’s exploitation of Nature, which is leading to a large scale depletion of natural resources, destruction of forests, and overuse of land for agriculture and habitation. Pollution is contaminating air, land, and water. Smoke from industries, homes and vehicles, is in the air. A smoky haze envelopes the major cities of the world. Industrial waste and consumer trash are choking streams and rivers, ponds and lakes, killing the marine life. Much of the waste is a product of modern technology. It is neither biodegradable nor reusable, and its longterm consequences are unknown. The viability of many animal and plant species, and possibly that of the humankind itself, is at stake. At the biotic level, humanity is facing a social justice crisis, which is caused by humanity’s confrontation with itself. The social justice crisis is that poverty, hunger, disease, exploitation and injustice are widespread. There are economic wars over resources and markets. The rights of the poor and the marginal are violated. Women, constituting half the world’s population, have their rights abused. Obviously, the contemporary human society is in the midst of a grave environmental crisis. There is a serious concern that the earth may no longer be a sustainable biosystem. Although human beings are seen as the most intelligent life form on earth, yet they are responsible for almost all the ecological damage done to the planet. The Sikh scripture, Sri Guru Granth Sahib (SGGS), declares that the purpose of human beings is to achieve a blissful state and to be in harmony with the earth and all of God’s creation. It seems, however, that humans have drifted away from that ideal. According to the Sikh scriptures, humans create their surroundings as a reflection of their inner state. Thus, the increasing barrenness of the earth reflects a spiritual emptiness within humans. (shrink)

I argue that Husserl’s transcendental account of the role of the lived body in sense-making is a precursor to Alva Noë’s recent work on the enactive, embodied mind, specifically his notion of “sensorimotor knowledge” as a form of embodied sense-making that avoids representationalism and intellectualism. Derrida’s deconstructive account of meaning—developed largely through a critique of Husserl—relies on the claim that meaning is structured through the complication of the “interiority” of consciousness by an “outside,” and thus might be thought to lend (...) itself to theories of mind such as Noë’s that emphasize the ways in which sense-making occurs outside the head. But while Derrida’s notion of “contamination” rightly points to an indeterminateness of meaning in an outside, extended, concrete lived world, he ultimately reduces meaning to a structure of signification. This casts indeterminateness in terms of absence, ignoring the presence of non-linguistic phenomena of embodied sense-making central to both the contemporary enactivist program and to the later Husserl, who is able to account for the indeterminateness of meaning in lived experience through his distinction between sense and more exact linguistic meaning. Husserl’s transcendental theory of meaning also allows for a substantive contribution to sense-making from the side of the perceived object—an aspect missing from Noë’s account. Thus, in contrast to Derrida and to Noë, Husserl accounts for sense-making in terms of both the lived body and the lived world. (shrink)

Due to intensive agriculture, rapid industrialization and anthropogenic activities have caused environmental pollution, land degradation and increased pressure on the natural resources and contributing to their adulteration. Bioremediation is the use of biological organisms to destroy, or reduce the hazardous wastes on a contaminated site. Bioremediation is the most potent management tool to control the environmental pollution and recover contaminated soil. Use of biological materials, coupled to other advanced processes is one of the most promising and inexpensive approaches for removing (...) environmental pollutants. Bioremediation technology is a beneficial alternative which leads to degrade of pollutants. This article presents the important biological organisms used in bioremediation technologies. (shrink)

This is a first tentative examination of the possibility of reinstating reduction as a valid candidate for presenting relations between mental and physical properties. Classical Nagelian reduction is undoubtedly contaminated in many ways, but here I investigate the possibility of adapting to problems concerning mental properties an alternative definition for theory reduction in philosophy of science. The definition I offer is formulated with the aid of non-monotonic logic, which I suspect might be a very interesting realm for testing notions concerning (...) localized mental-physical reduction. The reason for this is that non-monotonic reasoning by definition is about appeals made not only to explicit observations, but also to an implicit selection of background knowledge containing heuristic information. The flexibility of this definition and the fact that it is not absolute, i.e. that the relation of reduction may be retracted or allowed to shift without fuss, add at least an interesting alternative factor to current materialist debates.

In lieu of an abstract, here is a brief excerpt of the content:This Universalism Which Is Not OneLinda M. G. Zerilli (bio)Ernesto Laclau. Emancipation(s). London: Verso, 1996.Judging from the recent spate of publications devoted to the question of the universal, it appears that, in the view of some critics, we are witnessing a reevaluation of its dismantling in twentieth-century thought. One of the many oddities about this “return of the universal” 1 is the idea that contemporary engagements with it are (...) more or less of a piece, and that they reflect a growing consensus that poststructuralist political theories are incapable of generating a viable alternative to the collective fragmentation that characterizes late modernity. 2 The putative return to the universal marks, on this view, both a homecoming to Enlightenment ideals—purified of their more poisonous elements, of course—and a reconciliation of sorts between those who refuted these ideals and those who sought to realize them. Now that “we” all know and agree that poststructuralism is critically valuable but politically bankrupt; now that we all know and agree that the “old universal” was indeed a “pseudo-universal,” so the homecoming narrative goes; we can get on with the project of constructing a “new universal.” 3 This authentic universal would really be inclusive of all people, regardless of race, class, gender, sexuality, ethnicity, nationality, and whatever else attaches to the “embarrassing etcetera” that, as Judith [End Page 3] Butler reminds us, inevitably accompanies such gestures of acknowledging human diversity.Before signing on to this felicitous agreement about “the necessity of universalism,” we may wish to know whether we have anything like a minimal agreement in language, that is, whether we who speak of this universal are even speaking about the same thing. Apart from the not insignificant problem of translating from a philosophical to a political idiom, the whole question of this agreement is virtually occluded by the rush to rescue politics from the virulent particularisms that admit no common ground or sense of collective belonging. Presented in terms of the familiar binary couple, the choice between universalism and particularism seems settled by merely pointing to global and domestic political realities. Universalism is the only alternative to social fragmentation, wild child of the collapse of communism, the rise of deadly nationalisms, and the multiculturalist romance with particularism. To invoke the name of the universal in any affirmative sense is already to sign on to the political diagnosis and its solution.One of the many virtues of Ernesto Laclau’s Emancipation(s) is that it offers both an alternative to the binarisms spawned by the “return” to the universal (for example, false universalism/true universalism) and a trenchant critique of the original binary couple itself (universalism/ particularism). Demonstrating the imbrication of the universal and the particular, Laclau shows why it is a matter not of choosing one over the other but of articulating, in a scrupulously political sense, the relation between the two. He thus explicitly rejects the notion that this relation is one of mutual exclusion, and shows that the tendency to see it as just that has led to the impasse of the contemporary debate, an impasse that is glossed over in some highly visible academic cases by proclaiming the necessary return to the universal. Although the language of universalism as spoken by Laclau searches for some common ground between particularists and universalists, it is more by way of articulating their mutual contamination, that is, how each is rendered impure by the irreducible presence of the other.The Problem of UniversalsLaclau situates his collection of essays in the context of the increasingly polarized debate over multiculturalism, a debate in which the classical universalism of the philosophical tradition has come under serious question. Reading his essays, one comes to see the deep dependence of the entire contemporary discussion on this tradition, even when its metaphysical assumptions are explicitly rejected (as, say, in the work of Seyla Benhabib) or insufficiently comprehended (as in most of the popularized political discourse). Laclau’s book can help us to see that the political question of universalism cannot be posed properly as long as it remains tethered to the classical philosophical “problem of universals.” At stake in sorting out the affinities and...

To a superficial consideration, art criticism might appear as a profession of a parasitic nature, nourishing itself on what is produced by others: by artists. In fact, however, the relation between artistic practice and its criticism is more adequately conceived of as a sort of symbiosis. For, while it is true that criticism depends on and presupposes the existence of its objects - that is, works of art - on the other hand nothing would prevent good art from being equated (...) with and contaminated by bad art if critics ceased to draw a distinction between the two.
