When viewed as a question of distributive justice the evaluation of workfare typically reflects exclusively on the distribution of income: do the physically capable have a justified claim for state support, or is it fair to demand from those who do work to subsidise this support? Rarely is workfare appraised in terms of how it affects other parties such as employers or other workers, and on the structural effects the pattern of incentives it generates brings about, or as an issue (...) of distributive justice related to a more extensive range of objects of distribution such as access to pleasing jobs. -/- We propose to evaluate workfare by looking at its effects more broadly: (1) we discuss and dismiss on empirical grounds the two most common arguments in favour of workfare, namely that workfare develops self-reliance among participants and it is more economical in the use of altruism among taxpayers. (2) We suggest that workfare focuses on work as a burden and as a means to income, ignoring other beneficial aspects that are conducive to the worker’s self expression. These other benefits are distributed unevenly between two main groups: the privileged well off and the disadvantaged. (3) we argue that workfare functions as a mechanism to preserve these privileges to one class of workers at the expense of another. Or, to put it the other way, the payment of unconditional welfare to the long term unemployed might be justified as one method of mitigating unjustified privileges. (shrink)

If persons fully own themselves and can acquire, by unilateral acts, unconditional full property rights to previously unowned natural resources, then by these same principles of property they also own the products of their property and of their labour. But the principles of property are silent on the question of the division of joint products; the market is a form of co-operation in production which makes the total social product a joint product. In the circumstances of an unrestrained fully developed (...) market, therefore, it is not fully determinate what one's product is. Thus the holdings that each person ends up with cannot be justified merely in terms of ownership of products. I offer an explanation of why some may resist this view of the market. (shrink)

The principle that each person is his own property occupies an almost axiomatic status in right-wing liberal thought as well as in some egalitarian theories. I reject any, full or partial, notion of property with respect to oneself by showing that any appeal and any justifiability which may be associated with self-ownership can at most serve to ground rights which are demonstrably non-property rights. As a contrast to self ownership, I introduce the non-proprietarian notion of Original Freedom. I compare the (...) two with respect to the control, income, and transfer aspects of ownership and suggest that Original Freedom is the more intuitively acceptable. (shrink)

In this paper I present a moral account of the legal notion of deceptive advertising. I argue that no harmful consequences to the consumer need follow from a deceptive advertisement as such, and I suggest instead that one should focus on the consequences of permitting the practise of deceptive advertising on society as a whole. After a brief account of deceptive advertising, I move to discuss the role of the reasonable person standard in its definition. One interpretation of this standard (...) is empirical, aiming to objectify the quality of misleadingness in the advertisement. I offer an alternative normative interpretation which aims to draw the line between the advertiser's responsibility and that of the consumer, between misleading and miscomprehension. I then examine and reject several possible moral grounds for condemning and prohibiting deceptive advertising. These include: harm, in the sense of welfare, to the misled consumer; harm to competitors; and a violation or a reduction of the consumer's autonomy. Finally, I explain how the effect of the practise of deceptive advertising on society as a whole should inform our normative line-drawing between misleading and miscomprehension, and how it provides the basis for the moral evaluation of deceptive advertising.

This paper explores the possibility of extending Locke’s theory with respect to tangible property so that it might offer a feasible theoretical basis for intellectual property too. The main conclusion is that such an attempt must fail. Locke’s theory comes in three parts: a general justification of property which serves to explain why assets ought to be under the exclusive control of individuals; a positive method of private appropriation whereby an individual acquires a prima facie exclusive claim to previously commonly (...) held natural resources; and third, a negative requirement that other individuals’ crucial interests are not harmed by such an appropriation. For each of these, the difficulties involved in applying that part of the theory to the sphere of ideas are discussed, and a central aspect of intellectual property that raises the problems of application is highlighted.

Can Rawls’s theory provide a framework for assessing obligations to future generations? Extending the veil of ignorance so that participants in the original position do not know to which generation they belong appears to fail in this endeavour. Earlier generations cannot improve their situation by “cooperating” with later generations. Such circumstances, lacking mutuality, leave no room for an agreement or contract. Nevertheless, the original position can be reconstructed so as to model relations of mutuality between generations even if these are (...) absent from the real world. This chapter assesses earlier attempts to do this and provides a rationale for viewing the just savings principle as a clause in the full formulation of the difference principle. (shrink)

The orthodoxy on the concept of ownership is given by Honoré's list of incidents. The idea this portrays is as ownership as a very flexible concept. The main purpose of this paper is to argue that the concept of property has much more integrity than the notion of a bundle of incidents may suggest. The Libertarian Challenge claims that redistributive theories of Justice, in so far as they impose involuntary taxes, are inconsistent with property rights, and are therefore unjustifiable. One (...) response to the libertarian challenge is to present alternative conceptions of ownership that are based on less than the complete list of incidents. These conceptions, we are told, avoid the inconsistency inherent in redistributive taxation by rejecting the incidents that are the source of the inconsistency, while retaining the moral appeal by leaving in place the core incidents and thus remaining faithful to what is primarily justifiable in property rights. Such an approach has been taken by several writers (notably, Waldron, Christman, and Fried). These different attempts to present a "truncated", "bifurcated", or "purist" concept of property invariably fail. Taxation must be an infringement of property. The upshot of this is that a justification of redistributive taxation requires a restriction of property or abandoning it altogether rather than redefining it. (shrink)

Working from a "capitalist" theory of exploitation, based on a neo-classical account of economic value, I argue that guest workers are exploited. It may be objected, however, that since they are not citizens, any inequality that stems from their status as non-citizens is morally unobjectionable. Although host countries are under no moral obligation to admit guest workers as citizens, there are independent reasons that call for the extension of economic rights – the freedom of occupation in particular – to guestworkers. (...) Since the cause of unequal exchange rests in the fact that guest workers are deprived of these rights, rather than in their exclusion from citizenship per se, I conclude that they are exploited even if their exclusion from citizenship may be justified.

Antonio Negri wrote the two essays that comprise Time for Revolution while serving a prison sentence for alleged involvement with radical left-wing groups. Although the essays were written two decades apart, their concerns are the same: is there a place for resistance in a society utterly subsumed by capitalism? In the wake of the global crisis of capitalism heralded by the 2008 crash, the question has never been more relevant and Negri remains an insightful and passionate guide to (...) any attempt to answer it.

A sequent calculus is given in which the management of weakening and contraction is organized as in natural deduction. The latter has no explicit weakening or contraction, but vacuous and multiple discharges in rules that discharge assumptions. A comparison to natural deduction is given through translation of derivations between the two systems. It is proved that if a cut formula is never principal in a derivation leading to the right premiss of cut, it is a subformula of the conclusion. Therefore (...) it is sufficient to eliminate those cuts that correspond to detour and permutation conversions in natural deduction. (shrink)

This book defines, perhaps for the first time in the history of the intellectual and religious tradition of Islam, the meaning of worldview from the perspective of Islam. The definition is articulated in the gathering together of the fundamental elements in the vision of reality and truth that projects the worldview of Islam into a meaningful whole. This articulation of the definition involves also explanation and contradiction of the challenges to that vision encountered throughout the ages to the present time.

According to the negative principle of appropriation a person can acquire an unowned resource if doing so respects a certain condition (the Lockean proviso). Contrary to some views, a proviso of this sort is not incompatible with libertarianism. Moreover, no unilateral powers of acquisition can fail to consider the impact on the interests of others. Hence, a doctrine of appropriation must incorporate such a proviso. However, the several interpretations such a proviso can take on various dimensions will be either implausible (...) as a way of taking into consideration the interests of others, or unable to generate the kind and extent of property rights libertarians typically endorse.

Rawls's difference principle contains a certain normative ambiguity, so that opposing views, including strong inegalitarian ones, might find a home under it. The element that introduces this indeterminacy is the absence of an explicit reference to time . Thus, a society that agrees on the difference principle as the proper justification of basic political-economic institutions, might nevertheless disagree on whether their specific institutions are justified by that principle. Such disagreement would most often centre on issues of fact: will a more (...) egalitarian policy in fact prioritize the least well off or will a more libertarian policy do so? But facts are not the only possible points of contention. According to the fundamental indeterminacy, considering merely the sum of advantages to the least well off, the difference principle is indifferent among different flows of equal income over time. It cannot adjudicate among more or less unequal distributions across social groups when the sum income of the least advantaged group is constant. The fundamental indeterminacy lies at the bottom of three derivative indeterminacies: an adequate future discount rate, an acceptable absolute minimum, and a reasonable time interval. These might form the basis of political disagreement among self-proclaimed endorsers of the difference principle of left and right over the way the principal social-economic institutions ought to be structured and the distributions that ensue. Key Words: Rawls • equality • incentives • future discount rate • primary goods • well-being. (shrink)

Libertarianism attempts to establish a set of property rights as a complete political morality, its argument proceeding from liberty tout court, as the unique foundational aspect of well being that grounds rights. In this book, Attas presents a sympathetic reconstruction of the libertarian argument and then brings to bear a critical evaluation leading to an ultimate rejection of libertarianism. Exposing the limitations of libertarianism and disclosing its errors, Attas argues that the rights which libertarians adopt with respect to persons, natural (...) resources and products are indefensible given what liberty must be.

Medicine at the Crossroads is a collection of essays based a column originally published in the Waco-Tribune Herald by renowned cardiologist Dr. Michael Attas of Baylor University. It touches on three perspectives - the physician, the patient, and the healthcare system - and addresses some of the most pressing questions in medicine today.

Human rights are a construct of international law. Their legitimacy depends on them being informed by the deep-seated fact of global cultural pluralism and the concern of establishing a system that recognizes this pluralism, transcends a narrow parochial perspective and thus avoids the accusation of cultural or moral colonialism. There are two broad strategies to do this: by invoking an individualist-moral conception of HR designed to promote well-being and by invoking a social-political conception of HR aimed at preserving world peace (...) and stability. Economic rights are rights to commodify—to sell one’s labor, to buy goods and services and so on—under fair terms. That is to say, to take part in economic activities such as production and consumption within a distinctive social form by which they are mediated through exchange. I argue that endorsing rights of commodification is incompatible with a genuine concern with parochialism. Economic rights are neither necessary to protect some natural interest shared by all humans, nor the stability of a peaceful world order. Hence, economic rights should not be considered human rights.

David Miller argues that the proper principle to govern distribution in the economy is a principle of desert and that markets (at their best) distribute to the participating agents rewards that are proportional to their respective contributions. This is explained by appeal to the notion of marginal productivity, and by the theory that perfect competition results in a distribution according to marginal contribution. Marginal product in this sense is taken to be a measure of the producer's contribution to the consumer's (...) well-being, and so a proportionate reward is something he can be said to deserve. I discuss the relation between desert and justice and question the premise that desert is appropriate in the economic sphere. With respect to Miller's argument I claim, first, that there are several substantial and prevalent factors that cast serious doubt on the contention that the market distributes and rewards according to marginal contribution to any significant extent. Second, that marginal contribution is not a measure of contribution to well being and, therefore, it is not a morally relevant desert-basis. (shrink)

Situations of fundamentally opposing interests are such that, without some degree of trust, they will fail to advance. In this paper I consider war and the achievement of peace through a series of reciprocal steps as the primary setting in which to examine trust, its terms, and its limits. A surprising point that transpires is that, in the attempt to resolve situations that are fundamentally conflictive, there is often a tendency to take steps to promote something else, superficially resembling trust, (...) sometimes counterproductively at the expense trust. An analysis of trust consisting of three elements is offered: (1) Vulnerability: the truster expresses an inclination to put himself in a vulnerable position with respect to the trusted. (2) Benefit: for the purpose of some gain that will befall the truster if the trusted does not exploit this vulnerability. (3) Reciprocity: with the expectation that the trusted will be sufficiently motivated to reciprocate at least partly due to the fact that truster’s behaviour is informed by such an expectation. The problem of trust is then presented as the idea of overcoming the “trust gap”. It is this: given the trust gap, and the rational-prudential basis to distrust – what could after all enable trust? Overcoming the gap may be achieved in one of two ways. Metaphorically speaking, we can narrow the gap, making the risks involved less worrisome, even if not eliminating them all together. Thus, encouraging cooperation on the basis of self-regarding prudential reasons. Or we can bridge the gap, leaving the risks as they are while procuring non-prudential resources to encourage cooperation. Only the latter can be truly classified as trust. Three ways in which the gap may be bridged are specified: Non-prudential reasons to reciprocate trust (Empathy, Fairness, and Reciprocity) correspond to the three components of trust (Vulnerability, Benefit, Reciprocity). The three reasons are introduced with the help of a minor thought experiments the results of which get further support from psychological experimental literature. It is then shown how these features of the situation provide a moral reason and, therefore, an expectation to act trustworthily, and as such facilitate trust. The possibility of trust is thus explained on the basis of an idea of reasonableness, rather than instrumental rationality, sentiment, or faith. Finally, it is argued that narrowing the gap might detrimentally affect bridging the gap. Confidence building measures (guarantees, incentives, and sanctions), designed to narrow the trust gap and facilitate cooperation, may unwittingly demolish the foundations for bridging the gap. Some policy implications are tentatively proposed: (1) Don’t focus exclusively on narrowing the gap. (2) Manufacture “common knowledge”. (3)Take care when narrowing the gap not to thwart bridging the gap. (shrink)

Using labelled formulae, a cut-free sequent calculus for intuitionistic propositional logic is presented, together with an easy cut-admissibility proof; both extend to cover, in a uniform fashion, all intermediate logics characterised by frames satisfying conditions expressible by one or more geometric implications. Each of these logics is embedded by the Gödel–McKinsey–Tarski translation into an extension of S4. Faithfulness of the embedding is proved in a simple and general way by constructive proof-theoretic methods, without appeal to semantics other than in the (...) explanation of the rules. (shrink)

That every first-order theory has a coherent conservative extension is regarded by some as obvious, even trivial, and by others as not at all obvious, but instead remarkable and valuable; the result is in any case neither sufficiently well-known nor easily found in the literature. Various approaches to the result are presented and discussed in detail, including one inspired by a problem in the proof theory of intermediate logics that led us to the proof of the present paper. It can (...) be seen as a modification of Skolem’s argument from 1920 for his “Normal Form” theorem. “Geometric” being the infinitary version of “coherent”, it is further shown that every infinitary first-order theory, suitably restricted, has a geometric conservative extension, hence the title. The results are applied to simplify methods used in reasoning in and about modal and intermediate logics. We include also a new algorithm to generate special coherent implications from an axiom, designed to preserve the structure of formulae with relatively little use of normal forms. (shrink)

Various sources in the literature claim that the deduction theorem does not hold for normal modal or epistemic logic, whereas others present versions of the deduction theorem for several normal modal systems. It is shown here that the apparent problem arises from an objectionable notion of derivability from assumptions in an axiomatic system. When a traditional Hilbert-type system of axiomatic logic is generalized into a system for derivations from assumptions, the necessitation rule has to be modified in a way that (...) restricts its use to cases in which the premiss does not depend on assumptions. This restriction is entirely analogous to the restriction of the rule of universal generalization of first-order logic. A necessitation rule with this restriction permits a proof of the deduction theorem in its usual formulation. Other suggestions presented in the literature to deal with the problem are reviewed, and the present solution is argued to be preferable to the other alternatives. A contraction-and cut-free sequent calculus equivalent to the Hubert system for basic modal logic shows the standard failure argument untenable by proving the underivability of DA from A. (shrink)

A constructivisation of the cut-elimination proof for sequent calculi for classical, intuitionistic and minimal infinitary logics with geometric rules—given in earlier work by the second author—is presented. This is achieved through a procedure where the non-constructive transfinite induction on the commutative sum of ordinals is replaced by two instances of Brouwer’s Bar Induction. The proof of admissibility of the structural rules is made ordinal-free by introducing a new well-founded relation based on a notion of embeddability of derivations. Additionally, conservativity for (...) classical over intuitionistic/minimal logic for the seven (finitary) Glivenko sequent classes is here shown to hold also for the corresponding infinitary classes.

The present study is a differential study that describes the nature of the relationship between cooperation and altruistic behavior in a sample of gifted adolescents in three universities in Egypt and Kuwait University. It also identified the differences between males/females, and senior students/junior students in both cooperation and altruism. A total of 237 gifted adolescents—with average age 21.3 ± SD 2.6 years—from three Egyptian universities: Alexandria University, Sadat Academy for Management Sciences, and Suez University, and Kuwait University, were involved in (...) this study. Measures used in the study include the Scales for Rating the Behavioral Characteristics of Superior Students, Generative Altruism Scale, and The Cooperative/Competitive Strategy Scale. Results revealed that there is a significant positive relationship between altruism and cooperation among gifted adolescents. Also, findings show that there are statistically significant differences between males and females in both altruism and cooperation. In addition, there are differences statistically significant between senior students and junior students in both altruism and cooperation in favor of senior students. It is recommended that altruism and cooperation intervention-based programs should be designed to increase the adaptive behaviors of adolescents. (shrink)

Anti-realist epistemic conceptions of truth imply what is called the knowability principle: All truths are possibly known. The principle can be formalized in a bimodal propositional logic, with an alethic modality ${\diamondsuit}$ and an epistemic modality ${\mathcal{K}}$, by the axiom scheme ${A \supset \diamondsuit \mathcal{K} A}$. The use of classical logic and minimal assumptions about the two modalities lead to the paradoxical conclusion that all truths are known, ${A \supset \mathcal{K} A}$. A Gentzen-style reconstruction of the Church–Fitch paradox is presented (...) following a labelled approach to sequent calculi. First, a cut-free system for classical bimodal logic is introduced as the logical basis for the Church–Fitch paradox and the relationships between ${\mathcal {K}}$ and ${\diamondsuit}$ are taken into account. Afterwards, by exploiting the structural properties of the system, in particular cut elimination, the semantic frame conditions that correspond to KP are determined and added in the form of a block of nonlogical inference rules. Within this new system for classical and intuitionistic “knowability logic”, it is possible to give a satisfactory cut-free reconstruction of the Church–Fitch derivation and to confirm that OP is only classically derivable, but neither intuitionistically derivable nor intuitionistically admissible. Finally, it is shown that in classical knowability logic, the Church–Fitch derivation is nothing else but a fallacy and does not represent a real threat for anti-realism. (shrink)

A proof-theoretical treatment of collectively accepted group beliefs is presented through a multi-agent sequent system for an axiomatization of the logic of acceptance. The system is based on a labelled sequent calculus for propositional multi-agent epistemic logic with labels that correspond to possible worlds and a notation for internalized accessibility relations between worlds. The system is contraction- and cut-free. Extensions of the basic system are considered, in particular with rules that allow the possibility of operative members or legislators. Completeness with (...) respect to the underlying Kripke semantics follows from a general direct and uniform argument for labelled sequent calculi extended with mathematical rules for frame properties. As an example of the use of the calculus we present an analysis of the discursive dilemma. (shrink)

Structural proof theory is a branch of logic that studies the general structure and properties of logical and mathematical proofs. This book is both a concise introduction to the central results and methods of structural proof theory, and a work of research that will be of interest to specialists. The book is designed to be used by students of philosophy, mathematics and computer science. The book contains a wealth of results on proof-theoretical systems, including extensions of such systems from logic (...) to mathematics, and on the connection between the two main forms of structural proof theory - natural deduction and sequent calculus. The authors emphasize the computational content of logical results. A special feature of the volume is a computerized system for developing proofs interactively, downloadable from the web and regularly updated. (shrink)

With the economy deindustrialized and the working class decentralized, a call for alternative horizons for resistance: the university and the art world. What was once the factory is now the university. As deindustrialization spreads and the working class is decentralized, new means of social resistance and political activism need to be sought in what may be the last places where they are possible: the university and the art world. Gerald Raunig's new book analyzes the potential that cognitive and creative labor (...) has in these two arenas to resist the new regimes of domination imposed by cognitive capitalism. Drawing on Gilles Deleuze's concept of “modulation” as the market-driven imperative for the constant transformation and reinvention of subjectivity, in Factories of Knowledge, Industries of Creativity, Raunig charts alternative horizons for resistance. Looking at recent social struggles including the university strikes in Europe, the Spanish ¡Democracia real YA! organization, the Arab revolts, and the Occupy movement, Raunig argues for a reassessment of the importance of cultural and knowledge production. The central role of the university, he asserts, is not as a factory of knowledge but as a place of creative disobedience. (shrink)
