A great deal has been made of the question of whether nano-materials provide a unique set of ethical challenges. Equally important is the question of whether they provide a unique set of regulatory challenges. In the last 18 months, the US Environmental Protection Agency has begun the process of trying to meet the regulatory challenge of nano using the Toxic Substances Control Act (1976)(TSCA). In this central piece of legislation, ‘newness’ is a critical concept. Current EPA policy, we argue, does (...) not adequately (or ethically) deal with the novelty of nano. This paper is an exploration of how to do a better job of accounting for nanomaterials as ‘new.’ We explore three alternative ways that nanomaterials might be made to fall under the TSCA regulatory umbrella. Since nanomaterials are of interest precisely because of the exciting new properties that emerge at the nano-scale, each of these three alternatives must meet what we call the ‘novelty condition’ and avoid what we call the ‘central paradox’ of existing regulatory policy. Failure to meet either of these conditions is a moral failure. We examine both the strengths and weaknesses of each alternative in order to illuminate the conceptual, practical, and moral challenges of novelty. (shrink)

Science and engineering remain male-dominated professions in Canada and elsewhere. This is a disheartening fact for a society dedicated to providing equality of education and opportunity, and protection of the right to physical and psychological security of the person to all its citizens. Canadian women comprise 51% of the population, yet still hold down, on average, less than 10% of all jobs in the basic and applied sciences. Few women are found in the upper strata of the science hierarchy, whether (...) judged by income, by rank within the relevant professions, or by inclusion in the structures of government, industry, education or professional institutions which formulate science policy. The evidence is compelling that science as both power and knowledge is firmly located in white, Western, bourgeois, (compulsorily heterosexual) men's hands. (shrink)
A critical approach on tolerance can be done as an endeavor to asset its rational arguments brought in its support or/and as a justification of its moral value within the process of human being completion. The commitment to such critical task is more necessary as it is unyieldingness summon in contemporary debates in political religious and, especially moral contexts, it has been equally valorized and contested. The most remarkable analyses of this rather summary rubric for many and often contradictory connotations, (...) then concept, underline the idea that a limit-matter is at stake: can be tolerated the intolerable? Because these boundaries are hard to be distinguished the critical position intellectually reasonable seems to be that of examining if is not more socially profitable and morally justifiable to be tolerant rather than intolerant.Developing possible arguments for and against the universal value of tolerance, critical discourse imposes a very meaningful statement: to uphold our humanity, even the demand for our right to intolerance must be done within the framework and with the means of tolerance.

Hume's maxim consists of two principles which are logically independent of each other: (1) whatever is conceivable is possible; and (2) whatever is inconceivable is impossible. Thomas Reid offered several arguments against the former principle, while John Stuart mill argued against the latter. The primary concern of this paper is to examine whether Reid and mill were successful in calling Hume's maxim into question.
In his Essays on the Intellectual Powers of Man, Thomas Reid offers a barrage of objections to the view, held by David Hume, that conceivability implies possibility. In this paper, I present Reid's first two objections to the ‘maxim of conceivability’ and defend Hume from them. The first objection concerns our ability to understand impossible claims, while the second concerns thoughts about impossible claims (such as, for instance, the thought that they are impossible). Reid's objections have special force against (...) Hume because of his commitment to analyse all operations of the understanding in terms of conception. I argue that these objections fail, on the grounds that they presuppose substantive views about language which we are not warranted in attributing to Hume. Ultimately, Reid's objections help us draw out a set of intertwined issues about the language-mind relationship in Hume. (shrink)
The argument that follows has a certain air of prestidigitation about it. I attempt to show that, given a couple of innocent-seeming suppositions, it is possible to derive a positive and complete theory of normative ethics from the Humean maxim "You can't get ought from is." This seems, of course, absurd. If the reasoning isn't completely unhinged, you may be sure, the trick has to lie in those "innocent-seeming" props. And, in fact, you are right. But every argument has (...) to begin somewhere, and, however questionable, those suppositions just don't seem to harbor serious normative import. (shrink)
Is there any good reason for thinking that a concept is individuated by the condition for a thinker to possess it? Why is that approach superior to alternative accounts of the individuation of concepts? These are amongst the fundamental questions raised by Wayne Davis.
This paper is a discussion of Frege's maxim that it is only in the context of a sentence that a word has a meaning. Quine reads the maxim as saying that the sentence is the fundamental unit of significance. Dummett rejects this as a truism. But it is not a truism since it stands in opposition to a conception of meaning held by John Locke and others. The maxim denies that a word has a sense independently of (...) any sentence in which it occurs. Dummett says this denial is inconsistent with the fact that people understand sentences they have never heard before. The maxim is defended against this attack. (shrink)
This article examines the normative force of consent, explaining how consent works its “moral magic” in transforming the moral quality of conduct that would otherwise constitute a wrong against the consenting person. Dempsey offers an original account of the normative force of consent, according to which consent (when valid) creates an exclusionary permission . When this permission is taken up, the moral quality of the consented-to conduct is transformed, such that it no longer constitutes a wrong against the consenting person. (...) Building on this account of how consent works, Dempsey identifies two sets of cases in which consent fails to transform the moral quality of one’s conduct: cases in which one is consent-insensitive to the rational force of another’s consent, and cases in which one acts for sadistic reasons.

According to the traditional philosophical definition, you lie if and only if you assert what you believe to be false with the intent to deceive. However, several philosophers (e.g., Carson 2006, Sorensen 2007, Fallis 2009) have pointed out that there are lies that are not intended to deceive and, thus, that the traditional definition fails. In 2009, I suggested an alternative definition: you lie if and only if you say what you believe to be false when you believe that one (...) of Paul Grice's conversational norms (“Do not say what you believe to be false”) is in effect. Faulkner (forthcoming), Stokke (forthcoming), and Pruss (2012) have subsequently argued that my 2009 definition fails as well because it counts some statements that are clearly not lies as being lies. In this paper, I identify some additional counter-examples of this sort. But I argue that my 2009 definition can easily be revised to deal with such counter-examples once we clarify that the relevant norm is really against communicating something false rather than against merely saying it. Nevertheless, I show that even this revised version of my 2009 definition fails because it counts some statements that are lies as not being lies. Lies told by young children – which uncontroversially count as lies on the traditional philosophical definition – suggest that lying (as well as asserting in general) does not require believing that such a norm is in effect. Even so, I claim that, since all liars intend to do something that would violate this norm if it were in effect, there is a successful definition of lying that is at least in the spirit of my 2009 definition.

There is a widely accepted ancient principle which holds that effects must occur as soon as possible after their causes. This paper takes this principle seriously and shows that if one believes there are causal chains then one is forced to accept the view that the temporal order is discrete or that some causally related events form a dense sequence.
Christopher Hookway presents a series of essays on the work of Charles Sanders Peirce (1839-1913), the 'founder of pragmatism' and one of the most important and original American philosophers.
Kant frequently speaks as if all voluntary actions arise from our maxims as the subjective principles of our practical reason. But, as Michael Albrecht has pointed out, Kant also occasionally speaks as if it is only the rare person of “character” who acts according to principles or maxims. I argue that Kant’s seemingly contradictory claims on this front result from the fact that there are two fundamentally different ways that maxims of action can figure in the deliberation of the agent: (...) an agent can act on a maxim either because it promises agreeable results or because he deems it to be an intrinsically correct principle of action. Kant describes a maxim of the latter sort as “firm” and as indicative of “character” in the honorific sense. If the agent’s commitment to his maxim is instead conditional on its agreeable results, we can say he does not act “on principle” and in that sense does not act on maxims at all: rather than aiming at a set of results because the action that produces them conforms to his maxim, he acts according to his maxim because doing so promises (and only as long as it promises) the results he desires. Such an agent thus lacks the principled maxims of a person of character since his maxims are always for sale to the highest bidder. Kant allows that an evil person can approximate the ideal of a principled indifference to results, but claims that only morally good action can be wholly principled. This is also why maxims of action in conformity with duty can be acquired gradually through habituation whereas an authentically moral maxim must instead arise from a “revolution” in thought.

Though corporate social responsibility (CSR) is on the agenda of most major corporations, corporate executives still largely support the view that corporations should maximize the returns to their owners. There are two lines of defence for this position. One is the Friedmanian view that maximizing owner returns is the social responsibility of corporations. The other is a position voiced by many executives, that CSR and profits go together. This article argues that the first position is ethically untenable, while the latter (...) is not supported by empirical evidence. The implication is that there may be good reason for firms to deviate from a maxim of profit maximization. (shrink)
Decision theory, understood as providing a normative account of rationality in action, is often thought to be an adequate formalization of instrumental reasoning. As a model, there is much to be said for it. However, if decision theory is to adequately account for correct instrumental reasoning, then the axiomatic conditions by which it links preference to action must be normative for choice. That is, a choice must be rationally defective unless it proceeds from a preference set that satisfies the axiomatic (...) conditions. -/- The crucial feature of standard decision theory for present purposes is that it conceives rational action as maximizing, as doing the best that one can in terms of satisfying one’s preferences. For maximizing to be possible, the preference set in question must completely order a person’s options. But I have argued elsewhere that that condition is often unmet by actual preference sets, so maximizing is not always available. Given that it is not, satisficing deserves attention, both as the most important alternative to maximizing and for the lessons it can yield with respect to goal-directed action. With those lessons in hand, standard maximizing decision theory is reconsidered, with the aim of showing that it does not adequately represent the normative distinction between means and ends.

Maxims play a crucial role in Kant's ethical philosophy, but there is significant disagreement about what maxims are. In this two-part essay, I survey eight different views of Kantian maxims, presenting their strengths, and their weaknesses. Part I: Established Approaches, begins with Rüdiger Bubner's view that Kant took maxims to be what ordinary people of today take them to be, namely pithily expressed precepts of morality or prudence. Next comes the position, most associated with Rüdiger Bittner and Otfried Höffe, that (...) maxims are Lebensregeln, or 'life-rules'– quite general rules for how to conduct oneself based on equally general outlooks on how the world is. These first two interpretations make sense of Kant's claim, made in his anthropological and pedagogical writings, that we have to learn how to act on maxims, but they become less plausible in light of Kant's probable view that people always act on maxims – after all, how can people learn how to act on something they always act on anyway? The next two views, each advanced, at different times, by Onora O'Neill, make better sense of the fact that people always act on maxims, for they hold that maxims are intentions – either specific intentions, such as 'to open the door', or general intentions, such as 'to make guests feel welcome'– and it is perfectly sensible to claim that people always act on intentions. However, they face the same problem as the two previous views, which is that if people always act on maxims, what sense does it make to say they also have to learn how to act on them? Henry Allison, the main representative of the fifth view, claims, on the basis of Kant's doctrine of the 'highest maxim', that maxims are principles organized hierarchically, such that an agent endorses one maxim because she endorses a more general maxim. Unfortunately for Allison, there is little direct textual support for his claim that maxims are organized hierarchically. (shrink)
: A standard interpretation of Kantian "maxims" sees them as expressing reasons for action, implying that we cannot act without a maxim. But recent challenges to this interpretation claim that Kant viewed acting on maxims as optional. Kant's understanding of maxims derives from Christian Wolff, who regarded maxims as major premises of the practical syllogism. This supports the standard interpretation. Yet Kant also viewed commitments to maxims as essential for virtue and character development, which supports challenges to the standard (...) interpretation, and raises questions about the coherence of Kant's overall conception of the role of maxims in practical philosophy.

A property, F, is maximal i?, roughly, large parts of an F are not themselves Fs. Maximal properties are typically extrinsic, for their instantiation by x depends on what larger things x is part of. This makes trouble for a recent argument against microphysical superve- nience by Trenton Merricks. The argument assumes that conscious- ness is an intrinsic property, whereas consciousness is in fact maximal and extrinsic.
Some contemporary Kantians have argued that one could not be virtuous without having internalized certain patterns of awareness that permit one to identify and respond reliably to moral reasons for action. I agree, but I argue that this insight requires unrecognized, farreaching, and thoroughly welcome changes in the traditional Kantian understanding of maxims and virtues. In particular, it implies that one''s characteristic emotions and desires will partly determine one''s maxims, and hence the praiseworthiness of one''s actions. I try to show (...) this by pointing out an instability in the Kantian understanding of maxims. On the one hand, maxims are thought of as consciously affirmed, subjective principles of action. On the other hand, Kantians claim that nothing counts as an action, nor as morally assessable, unless it has a maxim. One cannot take both thoughts seriously without implausibly constricting the range of behavior that counts as action, hence as morally assessable. This difficulty can be overcome, I suggest, by jettisoning the idea that maxims must be consciously affirmed, and by stressing the way in which maxims are grounded in the pruning and shaping of one''s emotions and desires during socialization. This opens the door to a rich Kantian theory of virtue. It also raises questions about the scope and ground of our moral responsibility, which I address at the end of the paper. (shrink)
The notion of radical evil plays a more important role in Kant's moral theory than is typically recognized. In Religion Within the Limits of Mere Reason, radical evil is both an innate propensity and a morally imputable act – a paradoxical status that has prompted commentators to reject it as inconsistent with the rest of Kant's moral theory. In contrast, I argue that the notion of radical evil accounts for the beginning of moral responsibility in Kant's theory, since the act (...) of attributing radical evil to one's freedom is an inauguration into the autonomous stance.

This chapter considers the centrality of principles in Kant’s moral philosophy, their distinctively ‘Kantian’ character, why Kant presents a ‘metaphysical’ system of moral principles and how these ‘formal’ principles are to be used in practice. These points are central to how Kant thinks pure reason can be practical. These features have often puzzled Anglophone readers, in part due to focusing on Kant’s Groundwork, to the neglect of his later works in moral philosophy, in which the theoretical preliminaries of that first (...) essay are properly articulated. In part, however, these puzzles stem, directly or indirectly, from Kant’s opposition to moral empiricism, which is bound to puzzle Anglophone readers, whose default orientation is empiricist. Accordingly, particular attention is paid to Kant’s reasons for rejecting moral empiricism and for developing an alternative to it, to Kant’s account of how his universalization tests serve as criteria of morally obligatory, permissible or prohibited actions and to his account of what is morally wrong with actions which violate those criteria. Examining these points provides a compelling synopsis of Kant’s system of moral principles, centring on the key terms ‘practical reason’, ‘law’, ‘maxim’ and ‘Categorical Imperative’. (shrink)
The primary objective of this article is to develop a framework for analyzing the ethical foundations and implications of shareholder wealth maximization (SWM). Distinctions between SWM and the more widely examined construct of profit maximization are identified, the most significant being the central role played in SWM by the market mechanism for pricing the corporation''s securities. It is argued that empirical tests concerned with evaluating the ethical implications of SWM will almost surely involve a joint hypothesis. A number of recent (...) empirical studies aimed at testing hypotheses with explicit ethical content are reviewed. (shrink)
Maximizing act consequentialism holds that actions are morally permissible if and only if they maximize the value of consequences—if and only if, that is, no alternative action in the given choice situation has more valuable consequences.[i] It is subject to two main objections. One is that it fails to recognize that morality imposes certain constraints on how we may promote value. Maximizing act consequentialism fails to recognize, I shall argue, that the ends do not always justify the means. Actions with (...) maximally valuable consequences are not always permissible. The second main objection to maximizing act consequentialism is that it mistakenly holds that morality requires us to maximize value. Morality, I shall argue, only requires that we satisfice (promote sufficiently) value, and thus leaves us a greater range of options than maximizing act consequentialism recognizes. (shrink)
The authors propose a model for business ethics which arises directly from business practice. This model is based on a behavioral definition of the economic theory of profit maximization and situates business ethics within opportunity costs. Within that context, they argue that good business and good ethics are synonymous, that ethics is at the heart and center of business, that profits and ethics are intrinsically related.
According to Bayesian epistemology, the epistemically rational agent updates her beliefs by conditionalization: that is, her posterior subjective probability after taking account of evidence X, pnew, is to be set equal to her prior conditional probability pold(·|X). Bayesians can be challenged to provide a justification for their claim that conditionalization is recommended by rationality—whence the normative force of the injunction to conditionalize? There are several existing justifications for conditionalization, but none directly addresses the idea that conditionalization will be epistemically rational (...) if and only if it can reasonably be expected to lead to epistemically good outcomes. We apply the approach of cognitive decision theory to provide a justification for conditionalization using precisely that idea. We assign epistemic utility functions to epistemically rational agents; an agent’s epistemic utility is to depend both upon the actual state of the world and on the agent’s credence distribution over possible states. We prove that, under independently motivated conditions, conditionalization is the unique updating rule that maximizes expected epistemic utility. (shrink)

The issues discussed are, of course, highly complex, and space limitations prevent me from addressing them fully. Thus, the argument presented should be understood merely as the outline of an argument. (shrink)
Timothy Williamson has proposed that we should give a ‘knowledge first’ twist to David Lewis’s account of content, maintaining that for P to be the content of one’s belief is for P to be the content that would be attributed by an idealized interpreter working under certain constraints, and that the fundamental constraint on interpretation is a principle of knowledge maximization. According to this principle, an interpretation is correct to the extent that it maximizes the number of knowledgeable judgments the (...) subject comes out as making. Here I will argue against knowledge maximization and two fallback positions suggested by Williamson’s discussion. Williamson intends the principle of knowledge maximization to form the basis of an argument against a certain sort of skepticism about judgment. In the final section I argue that the kind of general response to judgment skepticism envisaged by Williamson is neither desirable nor necessary. (shrink)
A property, F, is maximal iff, roughly, large parts of an F are not themselves Fs. Maximal properties are thus extrinsic, for their instantiation by x depends on what larger things x is part of. Maximality makes trouble for a recent analysis of intrinsicality by Rae Langton and David Lewis. Their theory implies that “non-disjunctive” properties are intrinsic if they are independent of “loneliness”; but many ordinary, apparently nondisjunctive, properties satisfy this test but are nevertheless extrinsic in virtue of being (...) maximal.

International marketing practices, embedded in a strong ethical doctrine, can play a vital role in raising the standards of business conduct worldwide, while in no way compromising the quality of services or products offered to customers, or surrendering the profit margins of businesses. Adherence to such ethical practices can help to elevate the standards of behavior and thus of living, of traders and consumers alike. Against this background, this paper endeavors to identify the salient features of the Islamic framework of (...) International Marketing Ethics. In particular, it highlights the capabilities and strengths of this framework in creating and sustaining a strong ethical international marketing culture. At the heart of Islamic marketing is the principle of value-maximization based on equity and justice (constituting just dealing and fair play) for the wider welfare of the society. Selected key international marketing issues are examined from an Islamic perspective which, it is argued, if adhered to, can help to create a value-loaded global ethical marketing framework for MNCs in general, and establish harmony and meaningful cooperation between international marketers and Muslim target markets in particular.

In recent attempts at deriving morality from rationality expected utility theory has played a major role. In the most prominent such attempt, Gauthier'sMorals by Agreement, a mode of maximizing utility calledconstrained maximization is defended.

Second, I discuss the question of what the place of constrained maximization in utility theory might be. Third, (...)

Anselmian theists claim (a) that there is a being than which none greater can be conceived; and (b) that it is knowable on purely—solely, entirely—a priori grounds that there is a being than which none greater can be conceived. In this paper, I argue that Anselmian Theism gains traction by conflating different interpretations of the key description ‘being than which no greater can be conceived’. In particular, I insist that it is very important to distinguish between ideal excellence and maximal (...) possible excellence. At the end of my paper, I illustrate the importance of this distinction by applying my discussion to the recent defence of Anselmian Theism in Nagasawa (Philos Q 58:577–591, 2008). (shrink)
Hans Herzberger's 1973 essay 'Ordinal Preference and Rational Choice' is a classic milestone in the erosion of the idea that rational agents are maximizers of utility. By the time Herzberger wrote, many authors had replaced this claim with the thesis that rational agents are maximizers of preference. That is to say, it was assumed that at the moment of choice a rational agent has a weak ordering representing his or her preferences among the options available to the agent for choice (...) and that the rational agent restricts choice to one of the optimal options. Such an option is an available option judged at least as good as any other.Herzberger explored the prospects of weakening this ordinalist view of maximizing .. (shrink)
This collection of essays explores two competing views of practical rationality. How do we think about what we plan to do? One dominant answer is that we select the best possible option available. However, a growing number of philosophers would offer a different reply. Since we are not equipped to maximize, we must often choose the next best alternative--one that is no more than satisfactory. This strategy choice is called "satisficing" (a term coined by the economist Herb Simon).
Maxims play a crucial role in Kant's ethical philosophy, but there is significant disagreement about what maxims are. In this two-part essay, I survey eight different views of Kantian maxims, presenting their strengths and their weaknesses. In Part II: New Approaches, I look at three more recent views in somewhat greater detail than I do the five treatments canvassed in 'Recent Works on Kantian Maxims I: Established Approaches'. First, there is Richard McCarty's Interpretation, which holds that Kant's understanding of maxims (...) can be illuminated by placing them in the context of the Wollfian tradition, according to which maxims are the major premises of practical syllogisms. The next subject Maria Schwartz, holds that careful attention to Kant's distinction between rules and maxims, as well as Kant's concept of happiness, allows us to make sense of almost all of Kant's remarks on maxims. It may be, however, that on Schwartz's view agents turn out to perform actions as opposed to thoughtlessly habitual behaviors much less often than is plausible. This leads to the final approach, exemplified by Jens Timmermann, which is that Kant understands maxims equivocally. I claim that something like Timmermann's approach is the only way to make sense of all of what Kant has to say on maxims. (shrink)
We discuss two desirable properties of deflationary truth theories: conservativeness and maximality. Joining them together, we obtain a notion of a maximal conservative truth theory – a theory which is conservative over its base, but can’t be enlarged any further without losing its conservative character. There are indeed such theories; we show however that none of them is axiomatizable, and moreover, that there will be in fact continuum many theories of this sort. It turns out in effect that the deflationist (...) still needs some additional principles, which would permit him to construct his preferred theory of truth. (shrink)
The article is a reappraisal of the requirement of maximal specificity (RMS) proposed by the author as a means of avoiding "ambiguity" in probabilistic explanation. The author argues that RMS is not, as he had held in one earlier publication, a rough substitute for the requirement of total evidence, but is independent of it and has quite a different rationale. A group of recent objections to RMS is answered by stressing that the statistical generalizations invoked in probabilistic explanations must be (...) lawlike, and by arguing that predicates fit for occurrence in lawlike statistical probability statements must meet two conditions, at least one of which is violated in each of the counterexamples adduced in the objections. These considerations suggest the conception that probabilistic-statistical laws concern the long-run frequency of some characteristic within a reference class as characterized by some particular "description" or predicate expression, and that replacement of such a description by a coextensive one may turn a statement that is lawlike into another that is not. Finally, to repair a defect noted by Grandy, the author's earlier formulation of RMS is replaced by a modified version. (shrink)
Possible worlds are maximal possibilities. But what kind of thing is a maximal possibility? Not a maximal individual: there are maximal possibilities that are not maximal individuals, because each maximal individual could have any one of several maximal properties. And not a maximal property: there are maximal possibilities that are not maximal properties, because each maximal property could be had by any one of many possible maximal individuals. So if you like your worlds concrete, you should say that they are (...) maximal facts, and if you like your worlds abstract, you should say that they are maximal propositions. (shrink)
This article introduces two new concepts into the business ethics literature, moral management and moral maximization, and explains the ways to measure and implement these concepts using four major subcomponents of human rights, human freedoms, human equity, and human development. Each of these subcomponents is subdivided into eight factors or items, resulting in 32 specific and tangible measures of the morality of human behavior. Figures are provided to illustrate the relationships between moral management and moral maximization and their 32 submeasures.
. Human capabilities theory has emerged as an important framework for measuring whether various social systems promote human flourishing. The premise of this theory is that human beings share some nearly universal capabilities; what makes a human life fulfilling is the opportunity to exercise these capabilities. This essay proposes that the use of human capabilities theory can be expanded to assess whether a company has organized the work environment in such a way that allows workers to develop a variety of (...) human capabilities. This mode of analysis is put forward as a complement to the work of Mihaly Csikszentmihalyi, who has suggested that the key to promoting human well-being in the workplace is the maximization of flow experiences.

Recent semantic research has made increasing use of a principle, Maximize Presupposition, which requires that under certain circumstances the strongest possible presupposition be marked. This principle is generally taken to be irreducible to standard Gricean reasoning because the forms that are in competition have the same assertive content. We suggest, however, that Maximize Presupposition might be reducible to the theory of scalar implicatures. (i)First, we consider a special case: the speaker utters a sentence with a presupposition p which is not (...) initially taken for granted by the addressee, but the latter takes the speaker to be an authority on the matter. Signaling the presupposition provides new information to the addressee; but it also follows from the logic of presupposition qua common belief that the presupposition is thereby satisfied (Stalnaker, Ling Philos 25(5–6):701–721, 2002). (ii) Second, we generalize this solution to other cases. We assume that even when p is common belief, there is a very small chance that the addressee might forget it (‘Fallibility’); in such cases, marking a presupposition will turn out to generate new information by re-establishing part of the original context. We also adopt from Raj Singh (Nat Lang Semantics 19(2):149–168, 2011) the hypothesis that presupposition maximization is computed relative to local contexts—and we assume that these too are subject to Fallibility; this accounts for cases in which the information that justifies the presupposition is linguistically provided. (iii) Finally, we suggest that our assumptions have benefits in the domain of implicatures: they make it possible to reinterpret Magri’s ‘blind’ (i.e. context-insensitive) implicatures as context-sensitive implicatures which just happen to be misleading.

According to the received view, formalism – interpreted as the thesis that mathematical truth does not outrun the consequences of our maximal mathematical theory – has been refuted by Goedel's theorem. In support of this claim, proponents of the received view usually invoke an informal argument for the truth of the Goedel sentence, an argument which is supposed to reconstruct our reasoning in seeing its truth. Against this, Field has argued in a series of papers that the principles involved in (...) this argument – when applied to our maximal mathematical theory – are unsound. This paper defends the received view by showing that there is a way of seeing the truth of the Goedel sentence which is immune to Field's strategy. (shrink)
There is a systemic condition inherent in contemporary markets that compel managers not to pursue more morally preferable initiatives if those initiatives will require actions that conflict with profit maximization. Normative arguments for implementing morally preferable practices within the existing system fail because they are insufficient to counter-act the systemic conditions affecting decision-making that is focused on maximizing profit as the primary operational value. To overcome this constraint we must elevate a more normatively preferable value, ‚ideal environmental sustainability,’ to the (...) level of being the primary filtering value through which other competing values are evaluated, prioritized, and implemented. In order for this to occur in practice, a change must be made relative to the laws, rules, and regulations that define and guide the market. This can be done by suitably defining the epistemic constraint of impartiality utilizing Rawls’ notion of a ‚veil of ignorance’ as a heuristic device. (shrink)
This paper charts the concepts of grip and the bodily auxiliary in Maurice Merleau-Ponty to consider how they find expression in disability narratives. Arguing against the notion of “maximal grip” that some commentators have used to explicate intentionality in Merleau-Ponty, I argue that grip in his texts functions instead as a compensatory effort to stave off uncertainty, lack of mastery, and ambiguity. Nearly without exception in Phenomenology of Perception, the mobilization of “grip” is a signal of impending loss, and is (...) offered as a strategy for managing failure rather than as an example of sure-footed mastery. I read Merleau-Ponty alongside Mary Felstiner's Out of Joint: A Public and Private Story of Arthritis to explore these other, attenuated dimensions of grip. Finally, the paper turns to Harriet McBryde Johnson's memoir Too Late to Die Young as an example of a way of thinking disabled embodiment otherwise. (shrink)
Gauthier's argument for constrained maximization, presented inMorals by Agreement, is perfected by taking into account the possibility of accidental exploitation and discussing the limitations on the values of the parameters which measure the translucency of the actors. Gauthier's argument is nevertheless shown to be defective concerning the rationality of constrained maximization as a strategic choice. It can be argued that it applies only to a single actor entering a population of individuals who are themselves not rational actors but simple rule-followers. (...) A proper analysis of the strategic choice situation involving two rational actors who confront each other shows that constrained maximization as the choice of both actors can only result under very demanding assumptions.

Utilitarianism is commonly defined in very different ways, sometimes in a single text. There is wide agreement that it mandates maximizing some kind of good, but many formulations also require a pattern of distribution. The most common of these take utilitarianism to characterize right acts as those that achieve “the greatest good for the greatest number.” This paper shows important ambiguities in this formulation and contrasts it (on any plausible interpretation of it) withthe kinds of utilitarian views actually defended by (...) major proponents of utilitarianism. The aim is not to defend any of these views but to formulate them in a way that facilitates using them—or, more likely, some revised version suggested by the paper—in guiding decisions in business. The analysis provided here should also facilitate appraisal of utilitarianism, contribute to clarity in discussions of business ethics, and suggest a range of ethical standards that merit consideration for certain kinds of decision. If the results of the analysis are correct, a distributive reading of utilitarianism is at best misleading as a representation of itscentral thrust; it should not be described as the view that ethics calls for achieving “the greatest good for the greatest number”; and, understood as its major proponents take it, utilitarianism differs more from Kantian ethics than distributive readings imply and is more difficult to defend than it appears to be when viewed as intrinsically distributive.

On commonsense morality, there are two types of situations where an agent is not required to maximize the impersonal good. First, there are those situations where the agent is prohibited from doing so--constraints. Second, there are those situations where the agent is permitted to do so but also has the option of doing something else--options. I argue that there are three possible explanations for the absence of a moral requirement to maximize the impersonal good and that the commonsense moralist must (...) appeal to all three in order to account for the vast array of constraints and options we take there be.

In this paper I uncover the identities of the interlocutors of Pierre Bayle's Entretiens de Maxime et de Themiste, and I show the significance of these identities for a proper understanding of the Entretiens and of Bayle's thought more generally. Maxime and Themiste represent the philosophers of late antiquity, Maximus of Tyre and Themistius. Bayle brought these philosophers into dialogue in order to suggest that the problem of evil, though insoluble by means of speculative reason, could be dissolved and thus (...) avoided through mutual toleration. I conclude by comparing Bayle's "theodicy of toleration" with Kant's notion of authentic theodicy. (shrink)
Abstract: In this article, I offer a proposal to clarify what I believe is the proper relation between value maximization and stakeholder theory, which I call enlightened value maximization. Enlightened value maximization utilizes much of the structure of stakeholder theory but accepts maximization of the long-run value of the firm as the criterion for making the requisite tradeoffs among its stakeholders, and specifies long-term value maximization or value seeking as the firm’s objective. This proposal therefore solves the problems that arise (...) from the multiple objectives that accompany traditional stakeholder theory. I also discuss the Balanced Scorecard, which is the managerial equivalent of stakeholder theory, explaining how this theory is flawed because it presents managers with a scorecard that gives no score—that is, no single-valued measure of how they have performed. Thus managers evaluated with such a system (which can easily have two dozen measures and provides no information on the tradeoffs between them) have no way to make principled or purposeful decisions. The solution is to define a true (single dimensional) score for measuring performance for the organization or division (and it must be consistent with the organization’s strategy), and as long as their score is defined properly, (and for lower levels in the organization it will generally not be value) this will enhance their contribution to the firm.

The centerpiece of Jeffrey Bub's book Interpreting the Quantum World is a theorem (Bub and Clifton 1996) which correlates each member of a large class of no-collapse interpretations with some 'privileged observable'. In particular, the Bub-Clifton theorem determines the unique maximal sublattice L(R,e) of propositions such that (a) elements of L(R,e) can be simultaneously determinate in state e, (b) L(R,e) contains the spectral projections of the privileged observable R, and (c) L(R,e) is picked out by R and e alone. In (...) this paper, we explore the issue of maximal determinate sets of observables using the tools provided by the algebraic approach to quantum theory; and we call the resulting algebras of determinate observables, "maximal *beable* subalgebras". The capstone of our exploration is a generalized version of Bub and Clifton's theorem that applies to arbitrary (i.e., both mixed and pure) quantum states, to Hilbert spaces of arbitrary (i.e., both finite and infinite) dimension, and to arbitrary observables (including those with a continuous spectrum). Moreover, in the special case covered by the original Bub-Clifton theorem, our theorem reproduces their result under strictly weaker assumptions. This added level of generality permits us to treat several topics that were beyond the reach of the original Bub-Clifton result. In particular: (a) We show explicitly that a (non-dynamical) version of the Bohm theory can be obtained by granting privileged status to the position observable. (b) We show that Clifton's (1995) characterization of the Kochen-Dieks modal interpretation is a corollary of our theorem in the special case when the density operator is taken as the privileged observable. (c) We show that the 'uniqueness' demonstrated by Bub and Clifton is only guaranteed in certain special cases -- viz., when the quantum state is pure, or if the privileged observable is compatible with the density operator. We also use our results to articulate a solid mathematical foundation for certain tenets of the orthodox Copenhagen interpretation of quantum theory. For example, the uncertainty principle asserts that there are strict limits on the precision with which we can know, simultaneously, the position and momentum of a quantum-mechanical particle. However, the Copenhagen interpretation of this fact is not simply that a precision momentum measurement necessarily and uncontrollably disturbs the value of position, and vice-versa; but that position and momentum can never in reality be thought of as simultaneously determinate. We provide warrant for this stronger 'indeterminacy principle' by showing that there is no quantum state that assigns a sharp value to both position and momentum; and, a fortiori, that it is mathematically impossible to construct a beable algebra that contains both the position observable and the momentum observable. We also prove a generalized version of the Bub-Clifton theorem that applies to "singular" states (i.e., states that arise from non-countably-additive probability measures, such as Dirac delta functions). This result allows us to provide a mathematically rigorous reconstruction of Bohr's response to the original EPR argument -- which makes use of a singular state. In particular, we show that if the position of the first particle is privileged (e.g., as Bohr would do in a position measuring context), the position of the second particle acquires a definite value by virtue of lying in the corresponding maximal beable subalgebra. But then (by the indeterminacy principle) the momentum of the second particle is not a beable; and EPR's argument for the simultaneous reality of both position and momentum is undercut. (shrink)
In this paper, following an idea of Christophe Chalons. I propose a new kind of forcing axiom, the Maximality Principle, which asserts that any sentence varphi holding in some forcing extension $V^P$ and all subsequent extensions $V^{P\ast Q}$ holds already in V. It follows, in fact, that such sentences must also hold in all forcing extensions of V. In modal terms, therefore, the Maximality Principle is expressed by the scheme $(\lozenge \square \varphi) \Rightarrow \square \varphi$ , and is equivalent to (...) the modal theory S5. In this article. I prove that the Maximality Principle is relatively consistent with ZFC. A boldface version of the Maximality Principle, obtained by allowing real parameters to appear in φ, is equiconsistent with the scheme asserting that $V_\delta \prec V$ for an inaccessible cardinal δ, which in turn is equiconsistent with the scheme asserting that ORD is Mahlo. The strongest principle along these lines is $\square MP\!_{\!\!\!\!\!\!_{\!\!_\sim}}$ , which asserts that $MP\!_{\!\!\!\!\!\!_{\!\!_\sim}}$ holds in V and all forcing extensions. From this, it follows that $0^\#$ exists, that $x^\#$ exists for every set x, that projective truth is invariant by forcing, that Woodin cardinals are consistent and much more. Many open questions remain. (shrink)
In this paper, I develop an argument for the thesis that ‘maximality is extrinsic’, on which a whole physical object is not a whole of its kind in virtue of its intrinsic properties. Theodore Sider has a number of arguments that depend on his own simple argument that maximality is extrinsic. However, Peter van Inwagen has an argument in defence of his Duplication Principle that, I will argue, can be extended to show that Sider's simple argument fails. However, van Inwagen's (...) argument fails against a more complex, sophisticated argument that maximality is extrinsic. I use van Inwagen's own commitments to various forms of causation and metaphysical possibility to argue that maximality is indeed extrinsic, although not for the mundane reasons that Sider suggests. I then argue that moral properties are extrinsic properties. Two physically identical things can have different moral properties in a physical world. This argument is a counterexample to a classical ethical supervenience idea (often attributed to G.E. Moore) that if there is identity of physical properties in a physical world, then there is identity in moral properties as well. I argue moral value is ‘border sensitive’ and extrinsic for Kantians, utilitarians, and Aristotelians. (shrink)
One reason why humans don't behave according to standard game theoretical rationality is because it's not realistic to assume that everyone else is behaving rationally. An individual is expected to have psychological mechanisms that function to maximize his/her long-term payoffs in a world of potentially “irrational” individuals. Psychological decision theory has to be individualistic because individuals make decisions, not groups.
For each integer n ≥ 2, MVn denotes the variety of MV-algebras generated by the MV-chain with n elements. Algebras in MVn are represented as continuous functions from a Boolean space into a n-element chain equipped with the discrete topology. Using these representations, maximal subalgebras of algebras in MVn are characterized, and it is shown that proper subalgebras are intersection of maximal subalgebras. When A ∈ MV3, the mentioned characterization of maximal subalgebras of A can be given in terms of (...) prime filters of the underlying lattice of A, in the form that was conjectured by A. Monteiro.

Graham Priest has asked whether the consequence relation associated with the Anderson–Belnap system of Tautological Entailment,1 in the language with connectives ¬, ∧, ∨, and countably many propositional variables as tomic formulas, maximal amongst the substitution-invariant relevant consequence relations on this language. Here a consequence relation is said to be relevant just in case whenever for a set of formulas Γ and formula B, we have Γ B only if some propositional variable occurring in B occurs in at least one (...) formula in Γ. (It follows that relevant consequence relations are atheorematic in the sense that whenever Γ B for some such consequence relation , Γ = ∅.) Here I write up in more detail the upshot of the conversation – returning an affirmative answer to Priest’s question – about this in the common room that Greg Restall and I were participating in last Friday [ = October 6, 2006], dotting some “i”s and crossing some “t”s (and adding the odd further reflection).

Rational actions reflect beliefs and preferences in certain orderly ways. The problem of theory is to explain which beliefs and preferences are relevant to the rationality of particular actions, and exactly how they are relevant. One distinction of interest here is between an agent's beliefs and preferences just before an action's time, and his beliefs and preferences at its time. Theorists do not agree about the times of beliefs and desires that are relevant to the rationality of action. Another distinction (...) is between actions that would, in one sense or another, maximize expected utilities given relevant beliefs and desires, and actions, decisions for which would, in one sense or another, be stable. There is disagreement about the relevance of these things to the rationality of actions. Here, in the first part below, several possible positions on these issues are explained and compared. In the second part, I contrast perspectives on these issues, and comment on arguments that might be brought against the position I favor. In the third part, I restate and elaborate on this position.

Causal decision theory produces decision instability in cases such as Death in Damascus where a decision itself provides evidence concerning the utility of options. Several authors have proposed ways of handling this instability. William Harper (1985 and 1986) advances one of the most elegant proposals. He recommends maximizing causal expected utility among the options that are causally ratifiable. Unfortunately, Harper's proposal imposes certain restrictions; for instance, the restriction that mixed strategies are freely available. To obtain a completely general method of (...) handling decision instability, I step outside the confines of pure causal decision theory. I introduce a new kind of backtracking expected utility and propose maximizing it among the options that are causally ratifiable. In other words, I propose a hierarchical maximization of (1) conditional causal expected utility and (2) the new backtracking expected utility. I support this proposal with some intuitive considerations concerning the distinction between optimality and conditional optimality. And I prove that the proposal yields a solution in every finite decision problem. (shrink)
Suppose T is superstable. Let ≤ denote the fundamental order on complete types, [ p] the class of the bound of p, and U(--) Lascar's foundation rank (see [LP]). We prove THEOREM 1.

That the finiteness of U(p) in (...) Theorem 2 is necessary follows from THEOREM 3. There is an ω-stable theory with a type p ∈ S 1 (φ) such that (1) U(p) = ω + 1, and (2) there is a maximal descending chain of proper extensions of [ p] which has order type ω. (shrink)
We report results of an experiment testing for present-value maximization in intertemporal income choice. Two-thirds of subjects did not maximize present value. Through a series of experimental manipulations that impose costs on non-present value maximizers, we are able to reduce the level of violations substantially. We find, however, that a sizeable proportion of subjects continue to systematically violate present-value principles. Our interpretation is that these subjects either cannot or choose not to distinguish between t income and t expenditure in making (...) their choices. Self-management, bounded rationality, and sequence preference are suggested as possible explanations for such behavior. (shrink)
The efficiency argument for profit maximization says that corporations and their managers should maximize profits because this is the course of action that will lead to an or outcome (see e.g. Jensen 2001, 2002). In this paper, I argue that the fundamental problem with this argument is not that markets in the real world are less than perfect, but rather that the argument does not properly acknowledge the personal sphere. Morality allows each of us a sphere in which we are (...) free to pursue our personal interests, even if these are not optimal from the social point of view. But the efficiency argument does not come to terms with this feature of social life. (shrink)
In [60] N. Belnap presented an 8-element matrix for the relevant logic R with the following property: if in an implication A → B the formulas A and B do not have a common variable then there exists a valuation v such that v(A → B) does not belong to the set of designated elements of this matrix. A 6-element matrix of this kind can be found in: R. Routley, R.K. Meyer, V. Plumwood and R.T. Brady [82]. Below we prove (...) that the logics generated by these two matrices are the only maximal extensions of the relevant logic R which have the relevance property: if A → B is provable in such a logic then A and B have a common propositional variable.

A nagging problem for the consequentialist is the fact that a person who chooses the action-option that seems to her to maximize good consequences all toooften does not produce consequences as good as she would have produced had she thought about her decision in some other fashion. In response, indirect consequentialists typically recommend that one take advantage of whatever benefits the employment of a nonconsequentialist decision procedure may provide. But I argue here that the consequentialist cannot straightforwardly appropriate the decision (...) procedures of those averse to consequentialism. I show that indirect consequentialists treat decision procedures the very same way direct consequentialists treat actions, and thus all of the reasons why direct consequentialists fail to act as well as they can likewise plague the indirect consequentialists’ attempts to decide as well as they can. So despite the wishes of the indirect theorists, consequentialism turns out to be self-defeating after all. (shrink)
According to one prominent view of rationality, for the choice of alternative to be justified, it must be at least as good as other alternatives. Michael Jensen has recently invoked this view to argue that managers should act exclusively to maximize the long-run market value of economic enterprises. According to Jensen, alternative accounts of managerial responsibility, such as stakeholder theory, are to be rejected because they lack a single measure to compare alternatives as better or worse. Against Jensen’s account, this (...) paper argues that choosing the alternative that is at least as good as other alternatives need not preclude managers from respecting considerations in addition to long-run market value. The paper argues that such considerations may be incorporated into managerial decision-making by introducing constraints and priorities into the process of maximizing long-run market value and by allowing for “clumpy” values.

This paper explores the moral status of various gambling maxims, particularly as they relate to the bettor’s interest in profit and the mathematical expectation of the game being played. Certain difficulties with the prevailing interpretations of the Formula of Universalizability will also be discussed, particularly in relation to games for which the bettor can have a positive expectation.
The implicational fragment of the relevance logic "ticket entailment" is closely related to the so-called hereditary right maximal terms. I prove that the terms that need to be considered as inhabitants of the types which are theorems of $T_\rightarrow$ are in normal form and built in all but one casefrom B, B' and W only. As a tool in the proof ordered term rewriting systems are introduced. Based on the main theorem I define $FIT_\rightarrow$ - a Fitch-style calculus (related to (...) $FT_\rightarrow$ ) for the implicational fragment of ticket entailment. (shrink)
A computably enumerable (c.e.) degree is a maximal contiguous degree if it is contiguous and no c.e. degree strictly above it is contiguous. We show that there are infinitely many maximal contiguous degrees. Since the contiguous degrees are definable, the class of maximal contiguous degrees provides the first example of a definable infinite anti-chain in the c.e. degrees. In addition, we show that the class of maximal contiguous degrees forms an automorphism base for the c.e. degrees and therefore for the (...) Turing degrees in general. Finally we note that the construction of a maximal contiguous degree can be modified to answer a question of Walk about the array computable degrees and a question of Li about isolated formulas.

En el presente artículo, se examinan y discuten dos argumentos con consecuencias reduccionistas debidos a Jaegwon Kim y a Theodore Sider respectivamente. De acuerdo con el argumento de Kim, la superveniencia fuerte implicaría la coexistencia necesaria de propiedades (es decir, tal y como normalmente se interpreta, la reducción). De acuerdo con el de Sider, ocurriría lo mismo con la superveniencia global. Uno y otro hacen un uso esencial de sendas nociones de propiedad maximal, las cuales son discutidas aquí a la (...) luz de una interpretación natural e interesante de la teoría de las propiedades implícita en sus argumentos. Bajo esta nueva interpretación, en términos modelo-teóricos (véase apartado 4), obtenemos diversas posibilidades de relaciones formales entre las tesis de superveniencia y la reducción, según la lógica utilizada. Al menos bajo una interpretación interesante, los argumentos de Kim y Sider no son correctos, quedando demos-trado así que dichos argumentos no son válidos en general. We discuss and analyze two reductive arguments due to Jaegwon Kim and Theodore Sider respectively. According to the first one, strong supervenience would imply necessary coextension of properties (i.e., reduction). According to the second, this would be also the case of global supervenience. Kim and Sider make essential use of their respective notions of maximal properties, which we analyze here in the light of a natural and interesting interpretation of the underlying theory of properties. Under this interpretation, in terms of model theory (see § 4), we obtain different possibilities of formal relations between the superveniencie theses and reduction, depending on the logic we use. Under at least one interesting interpretation, the arguments of Kim and Sider are not correct and we become the conclusion that these arguments are not valid in general. (shrink)

The paper is concerned with the problem of characterization of strengthenings of the so-called Lukasiewicz-like sentential calculi. The calculi under consideration are determined byn-valued Lukasiewicz matrices (n>2,n finite) with superdesignated logical values. In general. Lukasiewicz-like sentential calculi are not implicative in the sense of [7]. Despite of this fact, in our considerations we use matrices analogous toS-algebras of Rasiowa.

Socio-economic decisions are commonly explained by rational cost versus benefit considerations, whereas person variables have not much been considered. The present study aimed at investigating the degree to which dispositional power motivation and affective states predict socio-economic decisions. The power motive was assessed both indirectly and directly using a TAT-like picture test and a power motive self-report, respectively. After 9 months, 62 students completed an affect rating and performed on a money allocation task (social values questionnaire). We hypothesized and confirmed (...) that dispositional power should be associated with a tendency to maximize oneâs profit but to care less about another partyâs profit. Additionally, positive affect showed effects in the same direction. The results are discussed with respect to a motivational approach explaining socio-economic behaviour. (shrink)
