Alternative theories to quantum mechanics motivate important fundamental tests of our understanding and descriptions of the smallest physical systems. Here, using spontaneous parametric downconversion as a heralded single-photon source, we place experimental limits on a class of alternative theories, consisting of classical field theories which result in power-dependent normalized correlation functions. In addition, we compare our results with standard quantum mechanical interpretations of our spontaneous parametric downconversion source over an order of magnitude in intensity. Our data match the quantum mechanical (...) expectations, and do not show a statistically significant dependence on power, limiting quantum mechanics alternatives which require power-dependent autocorrelation functions.

We describe in detail the first experimental test that distinguishes between an event-based corpuscular model of the interaction of photons with matter and quantum mechanics. The test looks at the interference that results as a single photon passes through a Mach-Zehnder interferometer. The experimental results, obtained with a low-noise single-photon source, agree with the predictions of standard quantum mechanics.

A centipede can walk until it thinks about howit does so. Thereafter it stumbles, over thesheer impossibility of the information andcoordination required. Life in the economy islittle different. Those engaged in productionand exchange discover, pragmatically, ways tomake them work. Those observing the processsee, realistically, the immense improbabilitythat it should do so. That most economies workin practice, but must pass such toughteleological tests to succeed in theory,highlights a difference between players' andspectators' outlook which may help to explainwhy the game has repeatedly (...) been thrown wideopen just when conclusive results seemed withinreach.Section 1 of this paper identifies the fourforms of realism which economists have tendedto adopt. Section 2 considers the pragmatism ofeconomic agents, when observed in action bypsychologists and management scholars notoverly steeped in economic theory. Theconcluding section reviews the ways in whicheconomists have tried to blur the distinction,by reclassifying agents as realistic or theirown views as pragmatic, and suggests that amore pragmatic economics might bridge thedivide.

Despite immediate appearances, this book is not primarily a hermeneutical exercise in which the superiority of one interpretation of canonical texts is championed against others. Its origin lies elsewhere, near the overlap of history, psychoanalysis, aesthetics, and social theory of the usual kind. Weber, Pareto, Freud, W. I. Thomas, Max Scheler, Karl Mannheim, and many others of similar stature long ago wondered and wrote much about the interplay between societal rationalization and individual rationality, between collective furor and private psychopathology—in short, (...) about the strange and worrisome union of “character and social structure” (to recall Gerth and Mills). Pondering the history of social thought in this century can lead to the unpleasant realization that such large-scale questions slipped away, especially from sociologists, sometime before World War II. Or, if not entirely lost, they were so transformed in range and rhetoric that a gap opened between contemporary theorizing and its European background. Perhaps this partly explains Weber’s continuing appeal. By dealing with him, one might again broach topics long at odds with “social science” of the last forty years.—From the Preface. (shrink)

Abstract:McMahan, Nussbaum, and Johannsen have recently suggested that humans should seek to eliminate predators from the wild or avoid reintroducing them if this can be done without great harm to an ecosystem. This is because predators cause a great deal of pain to those sentient animals which are their prey. This paper will first challenge the pragmatic aspects of such a position on the global level, arguing that it would be extremely difficult if not impossible to remove predators from the (...) environment without doing great ecological harm. Because removal of predators might be considered more feasible on the micro scale this paper will go on to challenge the axiological foundations of such a view. In particular defenders of the removal of predators from the environment tend to base their position on the preferencing of the disvalue of pain over the value of life. Yet if life itself has value it can be a good even with those beings that cause pain to others. Moreover, there is a value to diverse forms of life that must also be acknowledged. An ecosystem with diverse habits and life forms exercising different ways of being has great value even if again this comes at the cost of suffering and pain to some of the creatures in it. Once these things are understood it is clear that predators should not be eliminated from the wild and indeed should be reintroduced into ecosystems where they once flourished. (shrink)

We introduce a notion of complexity for interpretations, which is used to prove some new results about interpretations of sequential theories. In particular, we give a new, elementary proof of Pudlák's theorem that sequential theories are connected. We also demonstrate a counterexample to the infinitary distributive law $a \vee \bigwedge_{i \in I} b_i = \bigwedge_{i \in I} (a \vee b_i)$ in the lattice of chapters, in which the chapters a and b i are compact. (Counterexamples in which a is not (...) compact have been found previously.). (shrink)

Cultures around the world have regarded self-fulfillment as the ultimate goal of human striving and as the fundamental test of the goodness of a human life. The ideal has also been criticized, however, as egotistical or as so value-neutral that it fails to distinguish between, for example, self-fulfilled sinners and self-fulfilled saints. Alan Gewirth presents here a systematic and highly original study of self-fulfillment that seeks to overcome these and other arguments and to justify the high place that the (...) ideal has been accorded. He does so by developing an ethical theory that ultimately grounds the value of self-fulfillment in the idea of the dignity of human beings.Gewirth begins by distinguishing two models of self- fulfillment--aspiration-fulfillment and capacity-fulfillment--and shows how each of these contributes to the intrinsic value of human life. He then distinguishes between three types of morality--universalist, particularist, and personalist--and shows how each contributes to the values embodied in self-fulfillment. Building on these ideas, he develops a Odialectical' conception of reason that shows how human rights are central to self-fulfillment. Gewirth also argues that self-fulfillment has a social as well as an individual dimension: that the nature of society and the obstacles that disadvantaged groups face affect strongly the character of the self-fulfillment that persons can achieve.Bold in scope and rigorous in execution, Self-Fulfillment is a powerful new contribution to moral, social, and political philosophy.

Consider this propositional function which includes the dyadic predicate “loves”: “X does not love Y unless Y loves X” (or “if Y does not love X”). This function may be treated in four ways. (1) If universally quantified, it states a (purported) conceptual truth about “love” or the nature or essence of love. Love is necessarily reciprocal. (2) If universally quantified, it may alternatively be a nomological generalization stating an empirical or factual truth about human nature, i.e., about a pattern (...) of reciprocity that occurs among people who are independently identified as lovers. (3) If instantiated with constants, it is an empirical proposition about the attitudes or behaviors of particular individuals (a, b, c). Finally, (4) the function may be treated axiologically; it expresses a normative judgment about what love ought to be or what lovers ought to feel or do. Other propositional functions may be constructed for the constancy, exclusivity, and benevolence of love. This essay investigates the implications of these understandings of the function and how they are logically related to each other. (shrink)

In Value and Context Alan Thomas articulates and defends the view that human beings do possess moral and political knowledge but it is historically and culturally contextual knowledge in ways that, say, mathematical or chemical knowledge is not. In his exposition of "cognitive contextualism" in ethics and politics he makes wide-ranging use of contemporary work in epistemology, moral philosophy, and political theory.

This paper describes a new course in Medical Technology and Critical Decisions, part of the Technology Studies Program at Wellesley College, established with the support of the Alfred P. Sloan Foundation's New Liberal Arts Program. The course uses the dramatic new options in medicine presented by technology to individuals and society as a vehicle for promoting general technological literacy in liberal arts students. The course motivates the study of the scientific principles on which the technology rests and the mathematical principles (...) of a methodology for making rational choices. A case in point is the decision of a pregnant woman whether or not to undergo amniocentesis, a procedure used to determine the genetic make-up of a fetus from cells in the amniotic fluid. The course introduces students to the underlying notions of genetics; the physical principles behind the ultrasound imaging technique used to position the needle that draws the fluid; the probability and statistics needed to understand the risks to the woman and fetus both of having and of not having the procedure; and the methodology of decision analysis, increasingly used by genetic counselors to help prospective parents incorporate their personal values into the decision-making process.

This collection joins together sixty essays on the philosophy of love and sex. Each was presented at a meeting of The Society for the Philosophy of Sex and Love held between 1977 and 1992 and later revised for this edition. Topics addressed include ethical and political issues (AIDS, abortion, homosexual rights, and pornography), conceptual matters (the nature, essence, or definition of love, friendship, sexual desire, and perversion); the study of classical and historical figures (Plato, Aristotle, Spinoza, Kant, and Kierkegaard); and (...) issues in feminist theory (sexual objectification, the social construction of female sexuality, reproductive and marital arrangements). Authors include Jerome Shaffer, Sandra Harding, Michael Ruse, Richard Mohr, Russell Vannoy, Claudia Card, M.C. Dillon, Gene Fendt, Steven Emmanuel, T.F. Morris, Timo Airaksinen, and Sylvia Walsh. The editor, who is the author of Pornography (1986), The Structure of Love (1990), and Sexual Investigations (1996), has also contributed six pieces and an Introduction. (shrink)

oes anything exist outside culture? Is there anything that we do that is free of the distortions of our tastes and customs? That isn't irrevocably shaped by the languages we speak or our material interests? Is there anything out there that we can assume to be noncultural or transcultural or even universal?

In this Response to Hasko von Kriegstein, I defend several claims, including that the publicly-traded corporation and its assets are unowned; that managers may stand in fiduciary relations to shareholders that do not require managers to maximize shareholder wealth; and that the rights of a shareholder and of the owner of a privately-held corporation may differ fundamentally.

Thomas Nagel's criterion for an acceptable theory of conscious awareness, that it address the question of “what it is like” to be a conscious subject has been misunderstood in the light of an implicit act/object model of conscious awareness. Kant's account of conscious experience is an adverbial theory precisely in the sense that it avoids such an act/object interpretation. An “objectualist” and an “actualist” construal of views of conscious awareness are contrasted. The idea of an adverbial theory of conscious experience (...) is further developed by examining recent re-interpretations of Brentano as an adverbial theorist (Thomasson) or as an identity theorist (Hossack). Identity theory is independently criticized as a free standing account of consciousness. Kant's adverbial view is further developed and extended to an account of self-ascription and self-knowledge.

An organizing framework is set out for the diverse literature on business ethics in relation to strategic management. It consists of sets of bi-polar components, spanning themes and topical themes, with a derived typology of contributions. Then, in the spirit of classical pragmatism, the organizing framework is re-cast as an integrative conceptual model of the strategy–ethics relationship. The approach recognizes that both pragmatism and dialectics can underpin progress towards integration, encompassing both normative and empirical aspects.

How and why should hope play a key role in a twenty-first century democratic politics? Alan Mittleman offers a philosophical exploration of the theme, contending that a modern construction of hope as an emotion is deficient. He revives the medieval understanding of hope as a virtue, reconstructing this in a contemporary philosophical idiom. In this framework, hope is less a spontaneous reaction than it is a choice against despair; a decision to live with confidence and expectation, based on a (...) rational assessment of possibility and a faith in the underlying goodness of life. In cultures shaped by biblical teaching, hope is thought praiseworthy. Mittleman explores the religious origins of the concept of hope in the Hebrew Scriptures, New Testament, rabbinic literature and Augustine. He traces the roots of both the praise of hope, in Jewish and Christian thought, and the criticism of hope in Greco-Roman thought and in the tradition of philosophical pessimism. Arguing on behalf of a straightened, sober form of hope, he relates hope-as-a-virtue to the tasks of democratic citizenship. Without diminishing the wisdom found in tragedy, a strong argument emerges in favour of hope as a way of taking responsibility for the world. Drawing on insights from scriptural and classical texts, philosophers, and theologians - ancient and modern, Mittleman builds a compelling case for placing hope at the centre of democratic political systems.
