A systematic introduction suitable for readers who have little familiarity with logic. Provides numerous examples and complete proofs.

Hintikka and Sandu’s independence-friendly logic is a conservative extension of first-order logic that allows one to consider semantic games with imperfect information. In the present article, we first show how several variants of the Monty Hall problem can be modeled as semantic games for IF sentences. In the process, we extend IF logic to include semantic games with chance moves and dub this extension stochastic IF logic. Finally, we use stochastic IF logic to analyze the Sleeping Beauty problem, leading to (...) the conclusion that the thirders are correct while identifying the main error in the halfers’ argument.

IFG logic is a variant of the independence-friendly logic of Hintikka and Sandu. We answer the question: “Which IFG-formulas are equivalent to ordinary first-order formulas?” We use the answer to prove the ordinary cylindric set algebra over a structure can be embedded into a reduct of the IFG-cylindric set algebra over the structure.

The emergence of independent Chile in the early nineteenth century fostered debate over the appropriate model and function for historical study within the new nation. One school of thought, represented by Andres Bello, shunned all foreign historiographical models as inapplicable, and held that since Chilean historical knowledge was incomplete, priority ought to be given to close study of the facts. José Lastarria argued that the historian must be a philosopher of history, searching out the meaning of historical facts in order (...) to draw lessons for the present. In contrast to Bello, Lastarria believed the historical work should serve an active political function and offer judgments on both past and present. (shrink)

We present a compositional semantics for first-order logic with imperfect information that is equivalent to Sevenster and Sandu’s equilibrium semantics (under which the truth value of a sentence in a finite model is equal to the minimax value of its semantic game). Our semantics is a generalization of an earlier semantics developed by the first author that was based on behavioral strategies, rather than mixed strategies.

In this comprehensive collection of essays, most of which appear for the first time, eminent scholars from many disciplines—philosophy, economics, sociology, political science, demography, theology, history, and social psychology—examine the causes, nature, and consequences of present-day consumption patterns in the United States and throughout the world.

This paper seeks to contribute to the debate around sustainability by proposing the need for an ecocentric stance to sustainability that reflexively embeds humans in—rather than detached from—nature. We argue that this requires a different way of thinking about our relationship with our world, necessitating a engagement with the sociomaterial world in which we live. We develop the notion of ecocentrism by drawing on insights from sociomateriality studies, and show how radical-reflexivity enables us to appreciate our embeddedness and responsibility for (...) sustainability by bringing attention to the interrelationship between values, actions and our social and material world. We examine the implications of an ecocentric radically reflexive approach to sustainability for management education. (shrink)

Privacy is a basic and foundational human good meriting moral and legal protection. Privacy isn’t, however, everything. Other goods and values matter, too (Solove 2003; Ma...

Accountability protects public health and safety, facilitates law enforcement, and enhances national security, but it is much more than a bureaucratic concern for corporations, public administrators, and the criminal justice system. In Why Privacy Isn't Everything, Anita L. Allen provides a highly original treatment of neglected issues affecting the intimacies of everyday life, and freshly examines how a preeminent liberal society accommodates the competing demands of vital privacy and vital accountability for personal matters. Thus, "None of your business!" is (...) at times the wrong thing to say, as much of what appears to be self-regarding conduct has implications for others that should have some bearing on how a person chooses to act.

As a U.S. civil rights policy, affirmative action commonly denotes race-conscious and result-oriented efforts by private and public officials to correct the unequal distribution of economic opportunity and education attributed to slavery, segregation, poverty and racism. Opponents argue that affirmative action (1) violates ideals of color-blind public policies, offending moral principles of fairness and constitutional principles of equality and due process; (2) has proven to be socially and politically divisive; (3) has not made things better; (4) mainly benefits middle-class, wealthy (...) and foreign-born blacks; (4) stigmatizes its beneficiaries; and (5) compromises the self-esteem and self-respect of beneficiaries who know that they have been awarded preferential treatment. By way of a thought experiment, imagine that after decades of public policy and experimentation, the United States public finally came to agree: affirmative action is morally and legally wrong. Employing such a thought experiment, this essay by a beneficiary of affirmative action—written in response to James Sterba’s Affirmative Action for the Future (2009)—examines duties of moral repair and the possibility that the past beneficiaries of affirmative action owe apologies, compensation or some other highly personal form of corrective accountability. Beneficiaries of affirmative action have experienced woundedness and moral insecurity. Indeed, the practice of affirmative action comes with a psychology, a set of psychological benefits and burdens whose moral logic those of us who believe in our own fallibility—as much as we believe in the justice of what we have received and conferred on others—should address.

Here we examine the hypothesis that symbolic understanding across domains is mediated by a fundamental ‘symbolizing’ ability in young children. We tested 30 children aged 2–4 years on symbolic tasks assessing iconic and non-iconic word-referent and picture-referent understanding and administered standardised tests of symbolic play and receptive language. Children showed understanding of the symbol-referent relation earlier for pictures than written words, and performance within domains was correlated and, importantly, predicted by a marker of general symbolic ability. Performance on picture and (...) written word tasks was also unrelated to language comprehension. Thus, symbolic abilities in specific domains are underpinned by a general symbolizing ability which arises early in development. (shrink)

Is there any reason not to spy on other people as necessary to get the facts straight, especially if you can put the facts you uncover to good use? To “spy” is secretly to monitor or investigate another's beliefs, intentions, actions, omissions, or capacities, especially as revealed in otherwise concealed or confidential conduct, communications and documents. By definition, spying involves secret, covert activity, though not necessarily lies, fraud or dishonesty. Nor does spying necessarily involve the use of special equipment, such (...) as a tape recorder or high-powered binoculars. Use of a third party agent, such as a “private eye” or Central Intelligence Agency operative is not necessary for surveillance to count as spying. Spying is morally troublesome both because it violates privacy norms and because it relies on secrecy and, perhaps, nefarious deception. Contemporary technologies of data collection make secret, privacy-invading surveillance easy and nearly irresistible. For every technology of confidential personal communication - telephone, mobile phone, computer email - there are one or more counter-technologies of eavesdropping. But covert surveillance conducted by amateur and professional spies still includes old-fashioned techniques of stealth, trickery and deception known a half century ago: shadowing by car, peeking at letters and diaries, donning disguises, breaking and entering, taking photographs, and tape recording conversations. The ethical examination of spying cannot be reduced to a conversation about reigning in the mischief potential of twenty-first century technology. We do need to concern ourselves with what tomorrow's spies will do with nanotechnology, but plenty of spying is possible with the time-tested techniques of the Baby Boomers, or even, for that matter, the Victorians. The philosophical problem I wish to consider here is the ethical limits of spying on others, when the reasons for spying are good. I explore the plausibility of three interrelated ideas. The first idea is one I will call the anti-spying principle: spying on other adults is prima facie unethical. The second idea is an exception to the anti-spying principle: spying on others is ethically permissible, even mandatory, in certain situations, where the ends are good. The third and final idea is a constraint on exceptions to the anti-spying principle: where spying is ethically permitted or required, there are ethical limits on the methods of spying. The virtuous spy will violate privacy and transparency norms, of course; but he or she will, to the extent possible, continue to act with respect for the moral autonomy and for the moral and legal interests of the investigative target.

In the conclusion to this multi-part article I first review the discussions carried out around the six essential questions in psychiatric diagnosis – the position taken by Allen Frances on each question, the commentaries on the respective question along with Frances’ responses to the commentaries, and my own view of the multiple discussions. In this review I emphasize that the core question is the first – what is the nature of psychiatric illness – and that in some manner all (...) further questions follow from the first. Following this review I attempt to move the discussion forward, addressing the first question from the perspectives of natural kind analysis and complexity analysis. This reflection leads toward a view of psychiatric disorders – and future nosologies – as far more complex and uncertain than we have imagined. (shrink)
