This is a presentation on Charles Sanders Peirce's pragmatic philosophy, and the ay that it functions in his conception of epistemology.

Epistemic akrasia arises when one holds a belief even though one judges it to be irrational or unjustified. While there is some debate about whether epistemic akrasia is possible, this paper will assume for the sake of argument that it is in order to consider whether it can be rational. The paper will show that it can. More precisely, cases can arise in which both the belief one judges to be irrational and one’s judgment of it are epistemically rational in (...) the sense that both are supported by sufficient evidence.

According to the powerful qualities view, properties are both powerful and qualitative. Indeed, on this view the powerfulness of a property is identical to its qualitativity. Proponents claim that this view provides an attractive alternative to both the view that properties are pure powers and the view that they are pure qualities. It remains unclear, however, whether the claimed identity between powerfulness and qualitativity can be made coherent in a way that allows the powerful qualities view to constitute this sort (...) of alternative. I argue here that this can be done, given a particular conception of both the qualitativity and powerfulness of properties. On this conception, a property is qualitative just in the sense that its essence is fixed independently of any distinct properties, and it is powerful just if its essence grounds its dispositional role.

Ordinarily, we take moral responsibility to come in degrees. Despite this commonplace, theories of moral responsibility have focused on the minimum threshold conditions under which agents are morally responsible. But this cannot account for our practices of holding agents to be more or less responsible. In this paper we remedy this omission. More specifically, we extend an account of reasons-responsiveness due to John Martin Fischer and Mark Ravizza according to which an agent is morally responsible only if she is appropriately (...) receptive to and reactive to reasons for action. Building on this, we claim that the degree to which an agent is responsible will depend on the degree to which she is able to recognize and react to reasons. To analyze this, we appeal to relations of comparative similarity between possible worlds, arguing that the degree to which an agent is reasons-reactive depends on the nearest possible world in which given sufficient reason to do otherwise, she does so. Similarly, we argue that the degree to which an agent is reasons-receptive will depend on the intelligibility of her patterned recognition of reasons. By extending an account of reasons-responsiveness in these ways, we are able to rationalize our practice of judging people to be more or less responsible. (shrink)

This is the first chapter to our edited collection of essays on the nature and ethics of blame. In this chapter we introduce the reader to contemporary discussions about blame and its relationship to other issues (e.g. free will and moral responsibility), and we situate the essays in this volume with respect to those discussions.

Discussions about the nature of essence and about the inference problem for non-Humean theories of nomic modality have largely proceeded independently of each other. In this article I argue that the right conclusions to draw about the inference problem actually depend significantly on how best to understand the nature of essence. In particular, I argue that this conclusion holds for the version of the inference problem developed and defended by Alexander Bird. I argue that Bird’s own argument that this problem (...) is fatal for David Armstrong’s influential theory of the laws of nature but not for dispositional essentialism is seriously flawed. In place of this argument, I develop an argument that whether Bird’s inference problem raises serious difficulties for Armstrong’s theory depends on the answers to substantial questions about how best to understand essence. The key consequence is that considerations about the nature of essence have significant, underappreciated implications for Armstrong’s theory. (shrink)

A recent, seemingly appealing version of the powerful qualities view defines properties’ qualitativity via an essentialist claim and their powerfulness via a grounding claim. Roughly, this approach holds that properties are qualities because they have qualitative essences, while they are powerful because their instances or essences ground causal-modal facts. I argue that this theory should be replaced with one that defines the powerfulness of qualities in terms of both a grounding claim and a ‘meta-grounding’ claim. Specifically, I formulate and defend (...) a view on which qualities are powerful just if instances of those qualitiesat least partiallyground dispositionsin virtue of the essences of those qualities.

In De Anima 2.4, Aristotle claims that nutritive soul encompasses two distinct biological functions: nutrition and reproduction. We challenge a pervasive interpretation which posits ‘nutrients’ as the correlative object of the nutritive capacity. Instead, the shared object of nutrition and reproduction is that which is nourished and reproduced: the ensouled body, qua ensouled. Both functions aim at preserving this object, and thus at preserving the form, life, and being of the individual organism. In each case, we show how Aristotle’s detailed (...) biological analysis supports this ontological argument. (shrink)

I defend a new account of constitutive essence on which an entity’s constitutively essential properties are its most fundamental, nontrivial necessary properties. I argue that this account accommodates the Finean counterexamples to classic modalism about essence, provides an independently plausible account of constitutive essence, and does not run into clear counterexamples. I conclude that this theory provides a promising way forward for attempts to produce an adequate nonprimitivist, modalist account of essence. As both triviality and fundamentality in the account are (...) understood in terms of grounding, the theory also potentially has important implications for the relation between essence and grounding.

Robert Brandom makes several mistakes in his discussion of Sellars's "Two-Ply" account of observation. Brandom does not recognize the difference in "level" between observation reports concerning physical objects and 'looks'-statements. He also denies that 'looks'-statements are reports or even make claims. They then demonstrate a more correct reading of Sellars on 'looks'-statements.

According to the governing conception of the laws of nature, laws, in some sense, determine concrete goings-on. Just how to understand the sort of determination at play in governance is, however, a substantial question. One potential answer to this question, which has recently received some attention, is that laws govern by grounding what happens in the concrete world. If this account succeeded, it would show that governance can be understood in terms of an independently motivated and widely accepted notion. Thus (...) far, though, the grounding conception of governance has not been developed or evaluated in detail. In this paper, I fill this gap by mapping out and evaluating various possible ways of developing this conception of governance. My main conclusion is that the grounding conception runs into serious difficulties in trying to capture the key idea that governing laws determine the distribution of fundamental property instances.

Thaddeus Metz has developed and defended a “modal-relational” account of moral status based on his interpretation of salient Sub-Saharan African values. Roughly, on this account, a being has moral status to the degree that it can enter into friendly or communal relationships with characteristic human beings. In this paper, it is argued that this theory’s true significance for environmental ethics has thus far not been recognized. Metz’s own view is that the theory entails that only sentient beings have moral status. (...) It is argued here that this is a mistake, and that, once this error is corrected, the view can be used to synthesize major, competing accounts of moral status into a novel, unified account of the moral status of human beings, sentient animals, non-sentient organisms, and inanimate members of the “web of life”. The result is a new framework for thinking about the moral status of various natural entities, which ought to be of great interest to environmental ethicists. (shrink)

Does Aristotle offer a definition of the soul? In fact, he rejects the possibility of defining the soul univocally. Because “life” is a homonymous concept, so too is “soul”. Given the specific causal role that Aristotle envisages for form and essence, the soul requires multiple different definitions to capture how it functions as a cause in each form of life. Aristotle suggests demonstrations can be given which express these causal definitions; I reconstruct these demonstrations.

According to a well-known argument against dispositional essentialism, the nature of unmanifested token powers leaves dispositional essentialists with an objectionable commitment to the reality of non-existent entities. The idea is that, because unmanifested token powers are directed at their non-existent token manifestations, they require the reality of those manifestations. Arguably the most promising response to this argument works by claiming that, if properties are universals, dispositional directedness need only entail the reality of actually existing manifestation types. I argue that this (...) response fails, because no version of the response can adequately accommodate dispositions of the sort that follow from Coulomb’s law. This result both defeats an important argument that dispositional essentialists ought to be realists about universals and appears to leave dispositional essentialists with a problematic commitment to either non-relational connections or a Meinongian ontology.

Taylor has recently argued that adopting either the standard Kimian or Davidsonian approaches to the metaphysics of events quite directly solves the regress of pure powers. I argue, though, that on closer inspection Taylor’s proposal does not succeed, given either the Kimian or the Davidsonian account of events.

While the inference problem is widely thought to be one of the most serious problems facing non-Humean accounts of laws, Jonathan Schaffer has argued that a primitivist response straightforwardly dissolves the problem. On this basis, he claims that the inference problem is really a pseudo-problem. Here I clarify the prospects of a primitivist response to the inference problem and their implications for the philosophical significance of the problem. I argue both that it is a substantial question whether this sort of (...) response ought to be accepted and that the inference problem, contra Schaffer, remains a significant problem with important implications for the non-Humean position. I also argue that this discussion indicates grounds to be wary about applying the Schaffer-style strategy of straightforwardly dissolving problems by stipulation to other philosophical problems.

“Strong AI” is the view that it is possible for an artificial agent to be mentally indistinguishable from human agents. Because the behavioral dispositions of artificial agents are determined by underlying dispositional systems, Strong AI seems to entail human behavioral dispositions are also determined by dispositional systems. It is, however, highly intuitive that non-dispositional, phenomenal properties, such as being in pain, at least partially determine certain human behavioral dispositions, like the disposition to take a pain killer. Consequently, Strong AI seems (...) to conflict with an intuitive view of phenomenal properties’ role in determining human behavioral dispositions. My goal here is not directly to evaluate this tension, but rather to clarify how dispositionalism in the metaphysics of properties bears on it. While a tempting thought is that dispositionalism fits well with Strong AI’s thoroughly dispositional account of human behavior, I argue that this thought does not hold for dispositionalism in general. In particular, I argue that combining a version of the “powerful qualities view” with certain dispositionalist conceptions of the will leads to a version of the intuitive view of phenomenal properties that is radically incompatible with Strong AI. I argue further that this view also raises a challenge for the weaker claim that an artificial agent could be behaviorally indistinguishable from a human agent. (shrink)

Plato’s references to Empedocles in the myth of the Statesman perform a crucial role in the overarching political argument of the dialogue. Empedocles conceives of the cosmos as structured like a democracy, where the constituent powers ‘rule in turn’, sharing the offices of rulership equally via a cyclical exchange of power. In a complex act of philosophical appropriation, Plato takes up Empedocles’ cosmic cycles of rule in order to ‘correct’ them: instead of a democracy in which rule is shared cyclically (...) amongst equal constituents, Plato’s cosmos undergoes cycles of the presence and absence of a single cosmic monarch who possesses ‘kingly epistēmē’. By means of a revision of Empedocles’ democratic cosmology, Plato’s richly woven myth is designed precisely to reject the appropriateness of democracy as a form of human political association and legitimate monarchy in its stead.

This article argues the following points. The Hobbesian hypothesis, which we define as the claim that all people are better off under state authority than they would be outside of it, is an empirical claim about all stateless societies. It is an essential premise in most contractarian justifications of government sovereignty. Many small-scale societies are stateless. Anthropological evidence from them provides sufficient reason to doubt the truth of the hypothesis, if not to reject it entirely. Therefore, contractarian theory has not (...) done what it claims to do: it has not justified state sovereignty to each person subject to it by demonstrating that they benefit from that authority. To be justified in contractarian terms, states have to do something to improve the living standards of disadvantaged people under their rule. (shrink)

The Ockhamist claims that our ability to do otherwise is not endangered by God’s foreknowledge because facts about God’s past beliefs regarding future contingents are soft facts about the past—i.e., temporally relational facts that depend in some sense on what happens in the future. But if our freedom, given God’s foreknowledge, requires altering some fact about the past that is clearly a hard fact, then Ockhamism fails even if facts about God’s past beliefs are soft. Recent opponents of Ockhamism, including (...) David Widerker and Peter van Inwagen, have argued along precisely these lines. Their arguments, if successful, would undermine Ockhamism while avoiding the controversy over the alleged softness of facts about God’s past beliefs. But these arguments do not succeed. The past facts they rely on must be clear and uncontroversial examples of hard facts about the past, and these facts must be such that an ability to refrain from the relevant future action implies an ability to alter the relevant hard fact. We demonstrate the flaw in these arguments by showing how they rely on past facts that do not satisfy these criteria. The Ockhamist may have troubles, but this type of argument is not one of them.

: Agents are enkratic when they intend to do what they believe they should. That rationality requires you to be enkratic is uncontroversial, yet you may be enkratic in a way that does not exhibit any rationality on your part. Thus, what I call the enkratic requirement demands that you be enkratic in the right way. In particular, I will argue that it demands that you base your belief about what you should do and your intention to do it on (...) the same considerations. The idea is that, if you base your belief and your intention on different considerations, then you are inconsistent in your treatment of those considerations as reasons. The enkratic requirement demands that you be enkratic by treating considerations consistently as reasons. (shrink)

Storrs McCall continues the tradition of Lucas and Penrose in an attempt to refute mechanism by appealing to Gödel’s incompleteness theorem. That is, McCall argues that Gödel’s theorem “reveals a sharp dividing line between human and machine thinking”. According to McCall, “[h]uman beings are familiar with the distinction between truth and theoremhood, but Turing machines cannot look beyond their own output”. However, although McCall’s argumentation is slightly more sophisticated than the earlier Gödelian anti-mechanist arguments, in the (...) end it fails badly, as it is at odds with the logical facts.

McCall (1984) offered a semantics of counterfactual conditionals based on “real possible worlds” that avoids using the vague notion of similarity between possible worlds. I will propose an interpretation of McCall’s counterfactuals in a formal framework based on Baltag-Moss-Solecki events and protocols. Moreover, I will argue that using this interpretation one can avoid an objection raised by Otte (1987).

Conditionalists say that the value something has as an end—its final value—may be conditional on its extrinsic features. They support this claim by appealing to examples: Kagan points to Abraham Lincoln’s pen, Rabinowicz and Rønnow-Rasmussen to Lady Diana’s dress, and Korsgaard to a mink coat. They contend that these things may have final value in virtue of their historical or societal roles. These three examples have become familiar: many now merely mention them to establish the conditionalist position. But the widespread (...) faith in such cases is, I believe, unjustified. This is because, surprisingly, the pen, the dress, and the coat cannot have final value. I argue that the problem is internal: these cases are ruled out by every conditionalist account of final value. Further, the problem with these well-known cases applies to most other supposed examples of extrinsic, final goods. Thus nearly all cases given to support the conditionalist view cannot succeed. I suggest a kind of diagnosis: I claim that these examples are best seen as instances of sentimental value, rather than final value. I close by providing a brief account of sentimental value and explain how it relates to instrumental, intrinsic, and final goodness. (shrink)

McCall's system for contingent syllogisms is modified. A semantics for the resulting system is provided.

A semantics is presented for Storrs McCall's separate axiomatizations of Aristotle's accepted and rejected polysyllogisms. The polysyllogisms under discussion are made up of either assertoric or apodeictic propositions. The semantics is given by associating a property with a pair of sets: one set consists of things having the property essentially and the other of things having it accidentally. A completeness proof and a semantic decision procedure are given.

The seventeenth century Muslim philosopher Muhammad Sadr al-Din Shirazi, known as Mulla Sadra, introduced the idea of substantial motion in Islamic philosophy. This view is characterized by a continuity criterion for diachronic identity, a four-dimensional view of individual substances, the notion that possibilities change, and the continual creation of all creatures. Modern philosophical logic provides means to model a variety of claims about individuals, substances, modality and time. In this paper, the semantics of formal systems discussed by Carnap, Bressan and (...) Gupta are reviewed with regard to the issue of substance and identity. Next a model introduced by Storrs McCall is described that is able to build upon and yet resolve some of the issues about substance and identity as characterized by Bressan and others. McCall’s model is also shown to be able to provide an illustration of Mulla Sadra’s doctrine of substantial motion. (shrink)

D. Justin Coates argues that, in ‘Freedom and Resentment’, P. F. Strawson develops a modest transcendental argument for the legitimacy of our moral responsibility practices. I disagree with Coates’ claim that Strawson’s argument provides a justification, in Wittgenstein’s and/or Strawson’s sense of that term, of our responsibility practices. I argue that my interpretation of Strawson solves some difficulties with Coates’ argument, while retaining its advantages.

Fred's semantics for McCall's syntactic presentation of Aristotle's assertoric and apodeictic syllogistic is altered to free it from Thom's objections that it is unAristotelian. The altered semantics rejects Baroco-XLL and Bocardo-LXL, which Thom says Aristotle should have accepted. Aristotle's proofs that use ecthesis are formalized by using singular sentences. With one exception the (acceptance) axioms for McCall's system L-X-M are derivable. Formal proofs are shown to be sound.

Commentary to Leslie McCall's 2005 paper "The complexity of intersectionality", with a review of her main points and some critical remarks.

The words we call slurs are just plain vanilla descriptions like ‘cowboy’ and ‘coat hanger’. They don't semantically convey any disparagement of their referents, whether as content, conventional implicature, presupposition, “coloring” or mode of presentation. What distinguishes 'kraut' and 'German' is metadata rather than meaning: the former is the conventional description for Germans among Germanophobes when they are speaking in that capacity, in the same way 'mad' is the conventional expression that some teenagers use as an intensifier when they’re emphasizing (...) that social identity. That is, racists don’t use slurs because they’re derogatory; slurs are derogatory because they’re the words that racists use. To use a slur is to exploit the Maxim of Manner (or Levinson’s M-Principle) to signal one’s affiliation with a group that has a disparaging attitude towards the slur’s referent. This account is sufficient to explain all the familiar properties of slurs, such as their speaker orientation and “nondetachability,” with no need of additional linguistic mechanisms. It also explains some features of slurs that are rarely if ever explored; for example the variation in tone and strength among the different slurs for a particular group, the existence of words we count as slurs, such as 'redskin', which almost all of their users consider to be respectful, and the curious absence in Standard English of any commonly used slurs—by which I mean words used to express a negative attitude toward an entire group—for Muslims and women.

Introduction: Over the past twenty-five years the sporting body has been studied in a myriad of ways including via a range of feminist frameworks (Hall 1996; Lowe 1998; Markula 2003; George 2005; Hargreaves 2007) and gender-sensitive lenses (e.g. McKay 1994; Aoki 1996; Woodward 2008). Despite this developing corpus, studies of sport only rarely engage in depth with the ‘flesh’ of the lived sporting and exercizing body (Wainwright and Turner 2003; Allen-Collinson 2009) at least from a phenomenological angle, and in relation (...) to female embodiment. It seems that a more corporeally-grounded, phenomenological perspective on women’s sporting embodiment would be a welcome addition to extant studies. In this chapter I suggest that employing a feminist phenomenological framework can provide a powerful lens through which to explore the subjective, richly-textured, lived-body experiences of sport and exercise. Phenomenology of course offers only one of a multiplicity of avenues to investigate the body in sport, and this chapter provides just a small glimpse of its possibilities. To-date studies of sporting experience employing a phenomenological theoretical framework remain surprisingly under-developed (Kerry and Armour 2000), as do those using its ethnomethodological offspring (Coates 1999; Burke et al. 2008). Further, as Fisher (2000) notes, the significance of the interaction between phenomenology and feminism has only relatively recently begun to be explored. It seems timely, therefore, to address this intriguing, potentially productive, but sometimes uneasy nexus, focusing upon female running embodiment in this case. (shrink)

This paper contends that Stoic logic (i.e. Stoic analysis) deserves more attention from contemporary logicians. It sets out how, compared with contemporary propositional calculi, Stoic analysis is closest to methods of backward proof search for Gentzen-inspired substructural sequent logics, as they have been developed in logic programming and structural proof theory, and produces its proof search calculus in tree form. It shows how multiple similarities to Gentzen sequent systems combine with intriguing dissimilarities that may enrich contemporary discussion. Much of Stoic (...) logic appears surprisingly modern: a recursively formulated syntax with some truth-functional propositional operators; analogues to cut rules, axiom schemata and Gentzen’s negation-introduction rules; an implicit variable-sharing principle and deliberate rejection of Thinning and avoidance of paradoxes of implication. These latter features mark the system out as a relevance logic, where the absence of duals for its left and right introduction rules puts it in the vicinity of McCall’s connexive logic. Methodologically, the choice of meticulously formulated meta-logical rules in lieu of axiom and inference schemata absorbs some structural rules and results in an economical, precise and elegant system that values decidability over completeness.

Humean promotionalists about reasons think that whether there is a reason for an agent to ϕ depends on whether her ϕ-ing promotes the satisfaction of at least one of her desires. Several authors have recently defended probabilistic accounts of promotion, according to which an agent’s ϕ-ing promotes the satisfaction of one of her desires just in case her ϕ-ing makes the satisfaction of that desire more probable relative to some baseline. In this paper I do three things. First, I formalize (...) an argument, due to Jeff Behrends and Joshua DiPaolo, to the effect that Mark Schroeder’s and Stephen Finlay’s probabilistic accounts of promotion cannot be correct. Next, I extend this argument to a recent alternative offered by D. Justin Coates and show how Coates’ attempt to avoid the argument by introducing a distinction between ‘intrinsic’ and ‘extrinsic’ probability doesn’t help. Finally, I suggest an alternative way of understanding promotion in terms of increase in degree of fit between the causal upshot of an action and the content of a desire. I show how this view, disjunctively paired with probabilism about promotion, solves the problems with previous accounts. (shrink)

In some recent papers (G. ‘t Hooft and others), it has been argued that quantum mechanics can arise from classical cellular automata. Nonetheless, G. Shpenkov has proved that the classical wave equation makes it possible to derive a periodic table of elements, which is very close to Mendeleyev’s one, and describe also other phenomena related to the structure of molecules. Hence the classical wave equation complements Schrödinger’s equation, which implies the appearance of a cellular automaton molecular model starting from classical (...) wave equation. The other studies show that the microworld is constituted as a tessellation of primary topological balls. The tessellattice becomes the origin of a submicrospic mechanics in which a quantum system is subdivided to two subsystems: the particle and its inerton cloud, which appears due to the interaction of the moving particle with oncoming cells of the tessellattice. The particle and its inerton cloud periodically change the momentum and hence move like a wave. The new approach allows us to correlate the Klein-Gordon equation with the deformation coat that is formed in the tessellatice around the particle. The submicroscopic approach shows that the source of any type of wave movements including the Klein-Gordon, Schrödinger, and classical wave equations is hidden in the tessellattice and its basic exciations – inertons, carriers of mass and inert properies of matter. We also discuss possible correspondence with Konrad Zuse’s calculating space. (shrink)

This paper assesses branching spacetime theories in light of metaphysical considerations concerning time. I present the A, B, and C series in terms of the temporal structure they impose on sets of events, and raise problems for two elements of extant branching spacetime theories—McCall’s ‘branch attrition’, and the ‘no backward branching’ feature of Belnap’s ‘branching space-time’—in terms of their respective A- and B-theoretic nature. I argue that McCall’s presentation of branch attrition can only be coherently formulated on a (...) model with at least two temporal dimensions, and that this results in severing the link between branch attrition and the flow of time. I argue that ‘no backward branching’ prohibits Belnap’s theory from capturing the modal content of indeterministic physical theories, and results in it ascribing to the world a time-asymmetric modal structure that lacks physical justification.

Media reporters often announce that we are on the verge of bringing back the woolly mammoth, even while there is growing consensus among scientists that resurrecting the mammoth is unlikely. In fact, current “de-extinction” efforts are not designed to bring back a mammoth, but rather adaptations of the mammoth using close relatives. For example, Harvard scientists are working on creating an Asian elephant with the thick coat of a mammoth by merging mammoth and elephant DNA. But how should such creatures (...) be classified? Are they elephants, mammoths, or both? Answering these questions requires getting clear about the concept of reproduction. What I hope to show is that with an appropriate notion of reproduction—one for which I will argue—resurrecting a member of Mammuthus primigenius is a genuine possibility. (shrink)

This study set out to look into the relationship between metacognitive reading strategies and reading comprehension of Grade 11 Technical-Vocational-Livelihood modular distance learners of Pasay City East. A correlational research design was employed. The Metacognitive reading strategies served as the dependent variable while reading comprehension served as an independent variable. Random sampling was used to select the 116 respondents and MARSI R and McCall Crabbs Reading Proficiech test were the instruments. The findings of this study show a weak relationship (...) between metacognitive awareness of reading strategies and reading comprehension and the unachieved grade level which failed to reject the hypothesis that there was no significant relationship of metacognitive reading strategies and reading comprehension for Global and Problem-Solving reading strategies. It recommended that future researchers should employ other reading comprehension proficiency tests to validate the result of the existing study and include intervention through the utilization of metacognitive reading strategies as the appropriate strategy to address reading comprehension.

After displaying these tenets more fully, I (...) argue that Trinitarians would do well to hold Moreland’s and Craig’s trinity monotheism at arms length. (shrink)

The focus of the paper is the comparison between the two composite aluminum panels, respectively Alpolic and Durabond. The paper is going to explore their reaction when interacting with Tirana`s climatological factors and their tension strength through an experiment, in order to find out which panel displays the best performance. The construction urge is constantly evolving, especially in Tirana mostly because it is the main industrial and economical district of Albania. It is distinguished that innovative technology is being used in (...) facades of the new buildings. One of the features that finds massive use in façade coating in the city is the application of ventilated facades equipped with external aluminum composite panels. This paper is going to deal with two buildings with different typologies of external coating, including the different types of aluminum panels. The analysis will focus on identifying each panel property such as tension strength; their respond to various external factors; their thermal conductivity; and their manufacturing companies which have been selected and produced. Within this paper graphics displays of the records will be included, offering concentrated information and a high level of reliability for both aluminum composite panels. (shrink)

Milgram’s experiments, subjects were induced to inflict what they believed to be electric shocks in obedience to a man in a white coat. This suggests that many of us can be persuaded to torture, and perhaps kill, another person simply on the say-so of an authority figure. But the experiments have been attacked on methodological, moral and methodologico-moral grounds. Patten argues that the subjects probably were not taken in by the charade; Bok argues that lies should not be used in (...) research; and Patten insists that any excuse for Milgram’s conduct can be adapted on behalf of his subjects. (Either he was wrong to conduct the experiments or they do not establish the phenomenon of immoral obedience). We argue a) that the subjects were indeed taken in b) that there are good historical reasons for regarding the experiments as ecologically valid, c) that lies (though usually wrong) were in this case legitimate, d) that there were excuses available to Milgram which were not available to his subjects and e) that even if he was wrong to conduct the experiments this does not mean that he failed to establish immoral obedience. So far from ‘disrespecting’ his subjects, Milgram enhanced their autonomy as rational agents. We concede however that it might (now) be right to prohibit what it was (then) right to do. (shrink)

The expression of fragility has always been a difficult and complex matter for African Americans, for the discourse of mainstream media is set up to sustain their fragility while at the same time misrecognizing it. Even though the black public sphere split off from the dominant public sphere after the Civil War to enable distinctive forms of expression, the “practiced habits” of which Coates speaks continued in the structures of the dominant discourse. My essay will analyze the structure of (...) America’s indifference to fragility in three parts. In the first section, I will introduce a normative problematic that can track how the hegemonic public sphere uses the rhetoric of formal equality to subordinate and silence African Americans speech while it also opens a space for black speech to be heard rather than dismissed. I then will trace the silencing structures back to the Brown v. Board of Education Supreme Court decision of 1954, for this “progressive” decision provided a template for what can be said and cannot be said. The next second section examines how Ralph Ellison thematizes and revises the encounter between the black and dominant public spheres. In the last section of the essay, I analyze the ways that Ta-Nehisi Coates exposes the contemporary forms of these discursive structures. (shrink)

Numerous agricultural wastes are impractically discarded every day, and one of these is rice bran.

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)

Designer babies are often presented in the popular media as a kind of apocalyptical spectre of things to come in a brave new world where reproduction is the province of white coated scientists and potential parents in pursuit of trophy children. In this realm physical, intellectual, and social perfection is sought through the manipulation of genes and selection of favoured traits and attributes to the detriment of individuals who cannot compete and of society more generally through the loss of natural (...) selection. It is therefore a pleasure to discover a short readable book that sets out the discussion and its many nuances in concise and accurate terms that will be accessible to all and should help to dispel some of these science fiction myths through scholarly debate.This volume is part of a collection of books under the title Debating Matters that sprang out of a series of public debates organised by the Institute of Ideas. The conferences were intended to reinvigorate debate and the contestation of ideas and contemporary issues the Institute regards as “too frequently sidelined”. The arguments are presented by an authoritative who’s who of commentators who offer their own insightful readings of various aspects of the debate. Each essayist confirms the fact that the term “ designer babies ” is an inaccurate reflection of the current ability of science to actively fashion children with selected characteristics, and as a result ….

In a recent paper in this journal, McCall and Lowe (2003) argue that an understanding of Special Relativity reveals that the A theorist’s notion of temporal passage is consistent with the B theory of time. They arrive at this conclusion by considering the twins’ paradox, where one of two twins (T) travels to Alpha Centauri and back and upon her return has aged 30 years, while her earth-bound twin (S) has aged 40 years. This paper argues that their account (...) of temporal passage fails to reconcile the A theoretic notion of temporal passage with the B theory of time since the B theorist is at liberty to adopt this as an account of temporal passage as understood by the B theorist.

I argue that Sellars's philosophy of perception can be reconciled with recent work in enactive cognitive science. Sellars's critical realism holds that we perceive physical objects with perceptible properties as causally mediated by how these objects affect our sensory receptors. I argue that this theory, while basically right, downplays the role of embodiment in perception: perception essentially involves sensorimotor abilities. I argue that embodied critical realism can resolve the debate between Coates and Noe.

A fundamental problem in understanding the nature of time is explaining its directionality. This 1990 PhD thesis re-examines the concepts of time flow, the physical directionality of time, and the semantics of tensed language. Several novel results are argued for that contradict the orthodox anti-realist views still dominant in the subject. Specifically, the concept of "metaphysical time flow" is supported as a valid scientific concept, and argued to be intrinsic to the directionality of objective probabilities in quantum mechanics; the common (...) claims that quantum probability theory is time reversible is shown to be based on an analytic error, stemming from a false choice for the criterion for reversibility of probabilistic theories (recognized by Satosi Watanabe in the 1950s but ignored in all philosophical discussions); and a consistent semantics for tensed language (adapted from the tree model of Storrs McCall) is constructed, showing that the common rejection of "time flow" as having no meaningful semantics is false. These debates are still ongoing in almost exactly the same state they were pre-1990, and there is appears to be no visible progress in the subject. Critical points made against errors in the orthodox account (which has been sustained for 70 years by the anti-realist philosophy of time, typified by the "Pittsburg School" of Grunbaum-Earman-Norton-Roberts), are still not recognized in the philosophy of time or physics. Some key technical proofs in this thesis have been published in physics proper. See p.ii-iii for full original abstract. (This pdf is uploaded from the Massey University archive.). (shrink)

The thesis is that question or ”questioning” is a form of life and as such a precondition for the grammatical category. If I am going out and need my coat but cannot find it, then it is a question where my coat is, before – and even independently of whether – I ask it. It is a mode of a situation or of being in a situation so-and-so. Incidentally, the original meaning of ‘question’ (lat. ‘questio’) is not the linguistic one, (...) but “agenda” (“matter”, “issue”). Cf. “To be or not to be, that is the question”: that is what matters. A question may even characterise a historical epoch. What are the questions of our time – asked as well as unasked? (shrink)
