Aim of the paper is to revise Boolos’ reinterpretation of second-order monadic logic in terms of plural quantification ([4], [5]) and expand it to full second order logic. Introducing the idealization of plural acts of choice, performed by a suitable team of agents, we will develop a notion of plural reference . Plural quantification will be then explained in terms of plural reference. As an application, we will sketch a structuralist reconstruction of second-order arithmetic based on the axiom of infinite (...) à la Dedekind, as the unique non-logical axiom. We will also sketch a virtual interpretation of the classical continuum involving no other infinite than a countable plurality of individuals. (shrink)

This is a defense of John Stuart Mill’s proof of the principle of utility in the fourth chapter of his Utilitarianism. The proof is notorious as a fallacious attempt by a prominent philosopher, who ought not to have made the elementary mistakes he is supposed to have made. This book shows that he did not. The aim is not to glorify utilitarianism, in a full sweep, as the best normative ethical theory, or even to vindicate, on a more specific level, (...) Mill’s universalistic ethical hedonism as the best form of utilitarianism. The book is concerned only with Mill’s utilitarianism, and primarily with his proof of the principle of utility. The purpose is to show that Mill proceeds intelligibly and systematically in pursuing a well-defined project in the fourth chapter of Utilitarianism, and that he successfully defends what he sets out to establish in his proof of the principle of utility.

Formulations of Mill's principle of utility are examined, and it is shown that Mill did not recognize a moral obligation to maximize the good, as is often assumed. His was neither a maximizing act nor rule utilitarianism. It was a distinctive minimizing utilitarianism which morally obligates us only to abstain from inflicting harm, to prevent harm, to provide for others minimal essentials of well being (to which rights correspond), and to be occasionally charitable or benevolent.

A spate of legislations prohibiting cigarette smoking in enclosed public spaces, mainly on grounds of public health protection, recently swept across cities around the world. This is in tandem with a raft of increasingly restrictive national laws that emerged on the back of the ratification of the WHO Framework for Tobacco Control by more than one 168 countries in 2005. The central debate on the increasingly restrictive tobacco laws revolves on the extent to which public health interests justification should ground (...) political intervention in a private right as basic as tobacco smoking, which interestingly is often lumped in the food and beverage category. The pertinent legal and ethical questions therefore are the following: Is or should there be a general unrestricted right to tobacco smoking? If there were such a right, should public health or ethical considerations trump private right to smoke in enclosed public spaces? And if public health interests were so paramount, should they go farther and ground tobacco smoking proscription in all private and public spheres? Using ethical principles and rights-based arguments, the paper critically examines the legal and ethical ramifications of public health justification for tobacco smoking proscription in enclosed public spaces.

It is axiomatic that tobacco smoking is hazardous to health. The statistics are well documented and often very grim. For example, the 2008 World Health Organization Report on the global tobacco epidemic presented the following statistics: a hundred million people died of tobacco-related diseases globally in the 20th century; there are approximately over five million tobacco-related deaths every year; and an estimated one billion could die of tobacco-related diseases in this 21st century.Significantly, no other risky, self-indulgent addictive behaviors such as (...) cocaine abuse directly endanger bystanders as much as cigarette smoking or tobacco use endangers nonsmokers through secondhand tobacco smoke or inhaled environmental tobacco smoke. Environmental tobacco smoke comprises sidestream smoke and mainstream smoke. About 85 percent of environmental tobacco smoke is sidestream smoke, while the remainder is mainstream smoke. (shrink)

That's what I reckon morality is all about — how to preach, not how to act. My aim is not to answer this question of how to preach. I want to defend the claim that it is the, or at least a, central problem of ethics: that it is in fact the problem of what moral principles to accept.My argument consists of an account of what is involved in accepting a moral principle. By a moral principle I mean a kind (...) of principle about how people should act. Moral principles are not the only principles you can have about how people should act. There are principles of prudence, or rational self-interest. There are aesthetic principles, such as might be expressed in a remark like “you shouldn't put a magenta cushion on a scarlet sofa”. There are principles of etiquette. And no doubt there are others. I develop my account of morality by asking what distinguishes moral principles from the rest. (shrink)

Mill's famous proportionality statement of the Greatest Happiness Principle (GHP) is commonly taken to specify his own moral theory. And the discussion in which GHP is embedded -- Chapter 2 of Utilitarianism -- predominates the interpretation of Mill's normative philosophy. Largely because of these suppositions, Mill is traditionally read as a particular kind of utilitarian: a maximizing act-consequentialist. This paper argues that the canonical status accorded to Utilitarianism is belied by the text itself, as well as by its historical context, (...) and that this point largely undermines the orthodox interpretation of Mill. In fact, GHP was intended as the statement of a common creed, acceptable to the diverse class of philosophers Mill counted as utilitarian. Moreover, the discussion of substantive moral theory in Utilitarianism in several respects does not reflect his own view, and the work itself is much less important than it is almost universally taken to be -- though not, it turns out, by Mill himself.

A TRADITIONAL VIEW OF UTILITY AND RIGHTS According to a conventional view, no project could be more hopelessly misconceived than the enterprise of attempting a utilitarian derivation of fundamental rights. We are all familiar – too familiar, perhaps – with the arguments that support this conventional view, but let us review them anyway. We may begin by recalling that, whereas the defining value of utilitarianism – pleasure, happiness or welfare – contains no mention of the dignity or autonomy of human (...) beings, it is this value which utilitarianism in all its standard forms invokes as the criterion of right action. Worse, insofar as utilitarian policy must have as its goal the maximization of welfare conceived as an aggregate summed over the utilities of everyone affected, legal and political utilitarianism seems bound to have a collectivist bias, trading on the dangerous fiction of a social entity and ignoring the distinctness of separate selves with their several incommensurable claims. It seems that, if individuals can appear in the utilitarian calculus at all, it will only be as ciphers, abstract place-holders for units of welfare. For, as an aggregative value, utility must be indifferent to distribution, and insensitive to the preeminently distributive considerations marked by claims about rights. So, if whatever has utility can be broken down into units or elements which are subject to measurement or at least comparison by a common standard, then it will always be possible that a very great loss of welfare for one man or a few men can be justified if it produces a great many small increments of welfare for a vast multitude of men.

John Stuart Mill's commitment to liberty and individual development is one of the most exoteric themes of his moral and political philosophy. But the linkages between this commitment to liberty and development and Mill's conception of utility and principles of the good are not as commonly recognized. As part of a more general transformation of his utilitarianism, Mill repudiated Bentham's principles of the good and instead adopted a more sophisticated form of hedonism. While Bentham admits only the total quantity of (...) pleasure as contributing to value, Mill expands the circle to admit quality or kind of pleasure as well into the value reckoning. I have elsewhere interpreted and defended Mill's qualitative hedonism, and in this paper I can offer only a brief overview of that account and must largely assume its plausibility. Bentham and Mill agree that only pleasurable experiences and the absence of painful experiences have value and so both are called hedonists. But they have very different views about what properties of pleasures makes them valuable, or in other words what are the good-making properties of pleasure. Bentham thinks that only intensity and duration, or quantity, are good-making properties of pleasures, and thus he includes only these properties in measuring value. As a consequence, in the context of value measurement he is not interested in the kinds of things in which people take pleasure. But Mill is a qualitative hedonist, and thinks that the quality or kind of pleasure is also a good-making characteristic and thus should be included in value measurement. The things that are sources of pleasure matter to Mill. (shrink)
