The famous ‘trolley problem’ began as a simple variation on an example given in passing by Philippa Foot , involving a runaway trolley that cannot be stopped but can be steered to a path of lesser harm. By switching from the perspective of the driver to that of a bystander, Judith Jarvis Thomson showed how the case raises difficulties for the normative theory Foot meant to be defending, and Thomson compounded the challenge with further variations that created still more puzzles (...) of broader interest. In recent years, her thought experiments have even been co-opted by psychologists engaged in the empirical study of moral judgment . Yet more than thirty years after launching the trolley problem, Thomson has now strikingly reversed course, retracting the very claim she had originally used to raise puzzles for Foot. I shall argue that this reversal is a mistake, leading to a needlessly counterintuitive, contrarian position about damage-control cases. Instead of overturning her earlier position, her new variations merely uncover a surprising insight about the conditions under which one may permissibly sacrifice another for a good end.1. The central case at issue is what Thomson now calls Bystander's Two Options: you are a bystander who sees a runaway trolley headed toward five innocent people who cannot move off the track; you cannot stop the trolley, but you have access to a switch that will divert it onto a side track where one innocent person is trapped. Is it permissible to throw the switch and divert the trolley toward lesser harm? The common answer, and Thomson's earlier one, is that it is: in cases like this, where there is a public threat and we can act on it so …. (shrink)

This essay presents a philosophical and computational theory of the representation of de re, de dicto, nested, and quasi-indexical belief reports expressed in natural language. The propositional Semantic Network Processing System (SNePS) is used for representing and reasoning about these reports. In particular, quasi-indicators (indexical expressions occurring in intentional contexts and representing uses of indicators by another speaker) pose problems for natural-language representation and reasoning systems, because--unlike pure indicators--they cannot be replaced by coreferential NPs without changing the meaning of the (...) embedding sentence. Therefore, the referent of the quasi-indicator must be represented in such a way that no invalid coreferential claims are entailed. The importance of quasi-indicators is discussed, and it is shown that all four of the above categories of belief reports can be handled by a single representational technique using belief spaces containing intensional entities. Inference rules and belief-revision techniques for the system are also examined. (shrink)

Introduction: characterizing ethical realismIt is useful to begin a survey of recent work on ethical realism with a look at current disputes over what makes a theory of ethics count as ‘realist’ in the first place. Nearly all characterizations of ethical realism include some version of the following two core claims: Ethical discourse is assertoric and descriptive: ethical claims purport to state ethical facts by attributing ethical properties to people, actions, institutions, etc., and are thus true or false depending on (...) whether their descriptions of things are accurate or not . 1 At least some ethical claims, when literally construed, are true in the above sense.Sayre-McCord maintains that these two conditions are necessary and sufficient to characterize ethical realism; others argue that further conditions must be added to yield ethical realism, or at least ‘paradigmatic’ or ‘robust’ ethical realism. Before turning to that, however, it is worth noting that some have recently denied that the above two conditions are even necessary for ethical realism. In probing new work on metaethical taxonomy, Miller argues that the core of ethical realism is simply the metaphysical commitment to objective ethical properties and facts, which is strictly independent of the semantic claims above. If one holds that there are objective facts about the wrongness of slavery, for example, then one ought to count as an ethical realist regardless of whatever views one might hold about the semantics of the contingent forms of discourse that have evolved among language users. Even if our ethical discourse turns out primarily to express conative states ), or all moral claims turn out to be false because …. (shrink)

A computer can come to understand natural language the same way Helen Keller did: by using “syntactic semantics”—a theory of how syntax can suffice for semantics, i.e., how semantics for natural language can be provided by means of computational symbol manipulation. This essay considers real-life approximations of Chinese Rooms, focusing on Helen Keller’s experiences growing up deaf and blind, locked in a sort of Chinese Room yet learning how to communicate with the outside world. Using the SNePS computational knowledge-representation system, (...) the essay analyzes Keller’s belief that learning that “everything has a name” was the key to her success, enabling her to “partition” her mental concepts into mental representations of: words, objects, and the naming relations between them. It next looks at Herbert Terrace’s theory of naming, which is akin to Keller’s, and which only humans are supposed to be capable of. The essay suggests that computers at least, and perhaps non-human primates, are also capable of this kind of naming. (shrink)

The ‘default mode’ network refers to cortical areas that are active in the absence of goal-directed activity. In previous studies, decreased activity in the ‘default mode’ has always been associated with increased activation in task-relevant areas. We show that the induction of hypnosis can reduce anterior default mode activity during rest without increasing activity in other cortical regions. We assessed brain activation patterns of high and low suggestible people while resting in the fMRI scanner and while engaged in visual tasks, (...) in and out of hypnosis. High suggestible participants in hypnosis showed decreased brain activity in the anterior parts of the default mode circuit. In low suggestible people, hypnotic induction produced no detectable changes in these regions, but instead deactivated areas involved in alertness. The findings indicate that hypnotic induction creates a distinctive and unique pattern of brain activation in highly suggestible subjects. (shrink)

Ford’s Helen Keller Was Never in a Chinese Room claims that my argument in How Helen Keller Used Syntactic Semantics to Escape from a Chinese Room fails because Searle and I use the terms ‘syntax’ and ‘semantics’ differently, hence are at cross purposes. Ford has misunderstood me; this reply clarifies my theory.

An outline is given of the proof that the consistency of a κ⁺-Mahlo cardinal implies that of the statement that I[ω₂] does not include any stationary subsets of Cof(ω₁). An additional discussion of the techniques of this proof includes their use to obtain a model with no ω₂-Aronszajn tree and to add an ω₂-Souslin tree with finite conditions.

We discuss a research project that develops and applies algorithms for computational contextual vocabulary acquisition (CVA): learning the meaning of unknown words from context. We try to unify a disparate literature on the topic of CVA from psychology, first- and secondlanguage acquisition, and reading science, in order to help develop these algorithms: We use the knowledge gained from the computational CVA system to build an educational curriculum for enhancing students’ abilities to use CVA strategies in their reading of science texts (...) at the middle-school and college undergraduate levels. The knowledge gained from case studies of students using our CVA techniques feeds back into further development of our computational theory. Keywords: artificial intelligence, knowledge representation, reading, reasoning, science education, vocabulary acquisition. (shrink)

This project continues our interdisciplinary research into computational and cognitive aspects of narrative comprehension. Our ultimate goal is the development of a computational theory of how humans understand narrative texts. The theory will be informed by joint research from the viewpoints of linguistics, cognitive psychology, the study of language acquisition, literary theory, geography, philosophy, and artificial intelligence. The linguists, literary theorists, and geographers in our group are developing theories of narrative language and spatial understanding that are being tested by the (...) cognitive psychologists and language researchers in our group, and a computational model of a reader of narrative text is being developed by the AI researchers, based in part on these theories and results and in part on research on knowledge representation and reasoning. This proposal describes the knowledge-representation and natural-language-processing issues involved in the computational implementation of the theory; discusses a contrast between communicative and narrative uses of language and of the relation of the narrative text to the story world it describes; investigates linguistic, literary, and hermeneutic dimensions of our research; presents a computational investigation of subjective sentences and reference in narrative; studies children’s acquisition of the ability to take third-person perspective in their own storytelling; describes the psychological validation of various linguistic devices; and examines how readers develop an understanding of the geographical space of a story. This report is a longer version of a project description submitted to NSF.

Contextual vocabulary acquisition (CVA) is the deliberate acquisition of a meaning for a word in a text by reasoning from context, where “context” includes: (1) the reader’s “internalization” of the surrounding text, i.e., the reader’s “mental model” of the word’s “textual context” (hereafter, “co-text” [3]) integrated with (2) the reader’s prior knowledge (PK), but it excludes (3) external sources such as dictionaries or people. CVA is what you do when you come across an unfamiliar word in your reading, realize that (...) you don’t know what it means, decide that you need to know what it means in order to understand the passage, but there is no one around to ask, and it is not in the dictionary (or you are too lazy to look it up). In such a case, you can try to figure out its meaning “from context”, i.e., from clues in the co-text together with your prior knowledge. Our computational theory of CVA—implemented in a the SNePS knowledge representation and reasoning system [28]—begins with a stored knowledge base containing SNePS representations of relevant PK, inputs SNePS representations of a passage containing an unfamiliar word, and draws inferences from these two (integrated) information sources. When asked to define the word, definition algorithms deductively search the resulting network for information of the sort that might be found in a dictionary definition, outputting a definition frame whose slots are the kinds of features that a definition might contain (e.g., class membership, properties, actions, spatio-temporal information, etc.) and whose slot-fillers contain information gleaned from the network [6–8,20,23,24]. We are investigating ways to make our system more robust, to embed it in a naturallanguage-processing system, and to incorporate morphological information. Our research group, including reading educators, is also applying our methods to the develop-. (shrink)

H´ector-Neri Casta˜neda-Calder´on (December 13, 1924–September 7, 1991) was born in San Vicente Zacapa, Guatemala. He attended the Normal School for Boys in Guatemala City, later called the Military Normal School for Boys, from which he was expelled for refusing to fight a bully; the dramatic story, worthy of being filmed, is told in the “De Re” section of his autobiography, “Self-Profile” (1986). He then attended a normal school in Costa Rica, followed by studies in philosophy at the University of San (...) Carlos, Guatemala. He won a scholarship to the University of Minnesota, where he received his B.A. (1950), M.A. (1952), and Ph.D. (1954), all in philosophy. His dissertation, “The Logical Structure of Moral Reasoning”, was written under the direction of Wilfrid Sellars. He returned to teach in Guatemala, and then received a scholarship to study at Oxford University (1955–1956), after which he took a sabbatical-replacement position in philosophy at Duke University (1956). His first full-time academic appointment was at Wayne State University (1957– 1969), where he founded the philosophy journal Noˆus (1967, a counter-offer made to him by Wayne State to encourage him to stay there rather than to take the chairmanship of philosophy at the University of Pennsylvania). In 1969, he moved (along with several of his Wayne colleagues) to Indiana University, where he eventually became the Mahlon Powell Professor of Philosophy and, later, its first Dean of Latino Affairs (1978–1981). He remained at Indiana until his death. He was also a visiting professor of philosophy at the University of Texas at Austin (1962–1963) and a fellow at the Center for Advanced Study in the Behavioral Sciences (1981–1982). He received grants and fellowships from the Guggenheim Foundation (1967–1968), the T. Andrew Mellon Foundation, the National Endowment for the Humanities, and the National Science Foundation. He was elected President of the American Philosophical Association Central Division (1979– 1980), named to the American Academy of Arts and Sciences (1990), and received the Presidential Medal of Honor from the Government of Guatemala (1991). Casta˜neda’s philosophical interests spanned virtually the entire spectrum of philosophy, and his theories form a highly interconnected whole.. (shrink)

Although philosophical theologians have sometimes claimed that human beings are necessarily dependent on God, few have developed the idea with any precision. Jonathan Edwards is a notable exception, providing a detailed and often novel account of humanity’s essential ontological, moral, and soteriological dependence on God.

Recent years have seen a growth of interest in the great English idealist thinker T. H. Green (1836-82) as philosophers have begun to overturn received opinions of his thought and to rediscover his original and important contributions to ethics, metaphysics, and political philosophy. This collection of essays by leading experts, all but one published here for the first time, introduces and critically examines his ideas both in their context and in their relevance to contemporary debates.

This paper seeks to explore the significance of a specific kind of religious experience for the rationality of religious belief. The context for this is a gap between what is often allowed as rational and what is embraced as certain in the life of faith. The claim to certainty at issue is related to the work and experience of the Holy Spirit; this experience has a structure which is explored phenomenologically. Thereafter various ways of cashing in the epistemic value of (...) the purported claim to certainty are examined. (shrink)

Obtaining informed consent, an ethical obligation of nurses and other health care providers, occurs routinely when patients make health care decisions. The values underlying informed consent (promotion of patients’ well-being and respect for their self-determination) are embedded in the dominant American culture. Nurses who apply the USA’s cultural values of informed consent when caring for patients who come from other cultures encounter some ethical dilemmas. This descriptive study, conducted with Latino, Chinese and Anglo-American cancer patients in a large, public, west-coast (...) clinic, describes constraints on the informed consent process in a multicultural setting, including language barriers, the clinical environment, control in decision making, and conflicting desired health outcomes for health care providers and patients, and suggests some implications for nursing practice.

The growing interest in lifestyle campaigns as a means to promote public health has increased steadily during the past several decades. Governments, national health organizations, NGOs, and wealthy donors are collaborating with media professionals and academic scholars to address the pressing health issues of the 21st century. To counter the potential negative influences of hundreds of lifestyle advertising messages that media consumers are exposed to on a daily basis, health communication professionals are designing more sophisticated campaigns that blend beneficial health (...) information with various forms of entertainment media. This article discusses important ethical considerations raised by health professionals and media scholars and considers lifestyle campaigns within the context of competing ethical approaches to social change. A heuristic model is presented that facilitates a communitarian ethical approach to lifestyle campaigns, examining four important groups of stakeholders. Specific recommendations for future lifestyle campaigns based on this model are proposed. (shrink)

In the Fall of 1983, I offered a junior/senior-level course in Philosophy of Artificial Intelligence, in the Department of Philosophy at SUNY Fredonia, after returning there from a year’s leave to study and do research in computer science and artificial intelligence (AI) at SUNY Buffalo. Of the 30 students enrolled, most were computerscience majors, about a third had no computer background, and only a handful had studied any philosophy. (I might note that enrollments have subsequently increased in the Philosophy Department’s (...) AI-related courses, such as logic, philosophy of mind, and epistemology, and that several computer science students have added philosophy as a second major.) This article describes that course, provides material for use in such a course, and offers a bibliography of relevant articles in the AI, cognitive science, and philosophical literature. (shrink)

It is a matter of fact—and has been so for a considerable amount of time—that philosophy is taught at the pre—college level. However, to teach philosophy at that (or at any) level is one thing; to teach it well is quite another. Fortunately, it can be taught well, as a host of successful experiences and programs have shown. But in what ways can it be taught? Are there differences in the ways in which it can or should be taught at (...) the pre-college level from the ways in which it is taught in college? Are there differences in the ways in which it can or should be taught at the elementary-school level from ways in which it can or should be taught at the secondary-school level? There are other questions, of a similar nature, that the beginning college-level teacher of philosophy might ask: “I have never taught Introduction to Philosophy before; how should I go about it?” And there is a further question: Should it be taught at all? This question can, of course, be raised at any educational level, but it is especially acute at the elementary level. (shrink)

According to Jonathan Edwards, “consciousness and being are the same thing exactly.” “Nothing has any existence anywhere else…but either in created or uncreated consciousness”. The physical world, therefore, has no independent reality. “…the existence of all corporeal things is only ideas”. “The material universe exists only in the mind,” i.e., “it is absolutely dependent on the conception of the mind for its existence, and does not exist as spirits do…”. More accurately, “The substance of all bodies is the infinitely exact (...) and precise and perfectly stable idea in God’s mind together with His stable will that the same shall gradually be communicated to us and to other minds according to certain fixed and exact established methods and laws…”.

The increasing role played by medical ethicists in the clinical setting both as teachers and consultants has brought with it a demand for new methodologies that speak more precisely to the multiple problems encountered in actual attempts at case resolution. Some of these moves have to do with a revival of the truly classic case study approach to ethics, casuistry. This approach is anchored in the revelatory text of Jonsen and Toulmin, TheAbuseofCasuistry. A fine example of this methodology is an (...) article in TheJournalofClinicalEthics, Conjoined to this approach is a renewed interest in virtue ethics. The groundwork for this was laid by MacIntyre's masterful history of its demise in AfterVirtue. A clear and concise application of this ancient but always new approach is given in Pellegrino and Thomasma's book TheVirtuesinMedicalPractice. This way of doing ethics is particularly congenial to the practice of healthcare ethics in that it understands that virtue is just a rather fancy name for a good habit or skill. Since the practice of clinical medicine is quintessentially the learning and application of a range of often highly complex patterns of professional abilities and skills, a virtue ethics approach will allow for the concomitant development of a whole set of ethical skills. But both casuistry and virtue ethics may well be seen to be operative in a larger context now known as narrative ethics. (shrink)

This paper argues that in Augustine rationality in religion depends in important respects on religious social practice. This point is developed in reference to the questions of the reasonableness of a commitment to a particular religion, the meaningfulness of religious terms and concepts, and the truth and falsity of religious claims.

Renewed philosophical discourse about virtue ethics motivates the search for examples to inform and extend our thinking. In the case of environmental virtue ethics, I have decided to consult “America’s Lifestyle Expert,” Martha Stewart. Oft dismissed as a pop icon or model of domesticity, Martha’s business success is arguably a result of her claimed authority on what the good life entails and how we get it. Reviewing over 60 signed “Letters From Martha” from her monthly magazine Martha Stewart Living. (MSL) (...) I explored her presentations of current environmental topics including biodiversity, obligations to animals, gardening, global warming, and reliance on technology. I find that her work ultimately makes managing a household interesting, and encourages her public to take personal pride in everyday tasks done well. These are trademark Martha Stewart “good things.” Moreover, by connecting with a large audience few philosophers or scientists ever court, she is poised to help us manage our larger planetary household (sensu Gr. “oikos”) and frame a quality of life for future generations.

Examined the role of philosophical beliefs in psychotherapy approach preference. It was hypothesized that trainees would prefer approaches that most closely correspond to their personal philosophical beliefs. 59 students were given audiotaped presentations. Three dimensions of the Ss' philosophical commitments were examined in relation to their relative preferences for 3 therapy approaches: rationalist, constructivist and behavioral. Results show that Ss tended to prefer a specific approach that most corresponded to their own ontological, epistemological and causal commitments. This suggests a role (...) for philosophical beliefs in therapists' preferences for different theoretical orientations. 2012 APA, all rights reserved). (shrink)

The anti-realist nihilism of post-modernist thought provides a constant challenge for science and scientists not only to refute this view but to make clear what constitutes science and the scientific method. The author reviews the major arguments of post-modern thought and its criticism of science and then provides a point by point refutation. The Popperian notion of refutability and empiricality provide the cornerstone of this discussion. 2012 APA, all rights reserved).
