In this article I describe the theoretical underpinnings of 20th-century British philosopher W. D. Ross's approach to linking deontological and teleological decision making. I attempt to fill in what Ross left on the whole unanswered, that is, how to use his duties to resolve dilemmas. A case study in journalism demonstrates how to apply the theory. I conclude with an analysis of what I take to be the strengths and weaknesses in Ross's theory.

The goal of this article is to try to resolve two key problems in the duty-based approach of W. D. Ross: the source of principles and a process for moving from prima facie to actual duty. I use a naturalistic explanation for the former and a nine-step method for making concrete ethical decisions as they could be applied to journalism. Consistent with Ross's position, the process is complicated, particularly in tougher problems, and it cannot guarantee correct choices. Again consistent with (...) Ross, such complexity and uncertainty speak in the method's favor, given the difficulty—factual, motivational, and organizational—of ethics problems and decision making. (shrink)

Late in 1990, the Center for the Study of Ethics in the Professions at Illinois Institute of Technology (lIT) received a grant of more than $200,000 from the National Science Foundation to try a campus-wide approach to integrating professional ethics into its technical curriculum.! Enough has now been accomplished to draw some tentative conclusions. I am the grant's principal investigator. In this paper, I shall describe what we at lIT did, what we learned, and what others, especially philosophers, can learn (...) from us. We set out to develop an approach that others could profitably adopt. I believe that we succeeded. (shrink)

This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

Originally published in 1972, Should Trees Have Standing? was a rallying point for the then burgeoning environmental movement, launching a worldwide debate on the basic nature of legal rights that reached the U.S. Supreme Court. Now, in the 35th anniversary edition of this remarkably influential book, Christopher D. Stone updates his original thesis and explores the impact his ideas have had on the courts, the academy, and society as a whole. At the heart of the book is an eminently (...) sensible, legally sound, and compelling argument that the environment should be granted legal rights. For the new edition, Stone explores a variety of recent cases and current events--and related topics such as climate change and protecting the oceans--providing a thoughtful survey of the past and an insightful glimpse at the future of the environmental movement. This enduring work continues to serve as the definitive statement as to why trees, oceans, animals, and the environment as a whole should be bestowed with legal rights, so that the voiceless elements in nature are protected for future generations.

Environmental ethics has reached a certain level of maturity; further significant advances require reexamining its status within the larger realm of moral philosophy. It could aim to extend to nonhumans one of the familiar sets of principles subject to appropriate modifications; or it could seek to break away and put forward its own paradigm or paradigms. Selecting the proper course requires as the most immediate mission exploring the formal requirements of an ethical system. In general, are there constraints against bringing (...) our moral relations with different sorts of things under different mIes of govemance? In particular, how much independence can an environmental ethic (or ethics) aim to have? (shrink)

This essay explores the methodological contributions of leading ethicist, activist, and mujerista theologian Ada María Isasi-Díaz, for whom the category of lo cotidiano is central. Her work on lo cotidiano begs a basic epistemological question: How does one think critically from the standpoint of the everyday? What does conscientization look like from the perspective of lo cotidiano? In light of such questions, I explore what I find to be one of Isasi-Díaz’s most significant, yet underdeveloped, ideas — her articulation of (...) a ‘conscientized cotidiano.’ I expand this category further, drawing on the work of Agnes Heller, a major influence on Latin American and US Latina feminism, and John Dewey. Conversely, I show how Isasi-Díaz’s attention to issues of religion and gender serves as a constructive counterpoint to the work of these philosophers. (shrink)

Abstract:Ninety years ago, John Dewey’s discussion of “the religious”—as distinct from traditional “religion”—opened new ways of thinking about the connection between spirituality and everyday forms of human action. But in what ways does our contemporary religious landscape invite us to reimagine and reconstruct Deweyan approaches to religion? This essay addresses this question by focusing on how the community of El Paso, Texas came together to respond to one of the worst racially motivated mass shootings in recent history. This community’s use (...) of spirituality, art, and institutional religion all corroborate key Deweyan insights and invite us to stretch them further. (shrink)

We have only limited awareness of the system by which we control our actions and this limited awareness does not seem to be concerned with the control of action. Awareness of choosing one action rather than another comes after the choice has been made, while awareness of initiating an action occurs before the movement has begun. These temporal differences bind together in consciousness the intention to act and the consequences of the action. This creates our sense of agency. Activity in (...) the anterior cingulate cortex and medial prefrontal cortex is associated with awareness of our own actions and also occurs when we think about the actions of others. I propose that the mechanism underlying awareness of how our own intentions lead to actions can also be used to represent the intentions that underlie the actions of others. This common system enables us to communicate mental states and thereby share our experiences. (shrink)

The Quaestiones super Physica Aristotelis traditionally attributed to Iohannes Canonicus survive in over 35 manuscripts and at least 8 printings from 1475 to 1520. Yet historians have disagreed about the century, the place of origin, the name and the institutional position of the author. This brief paper combines old and new evidence proving that the text was authored by an Augustinian Canon Regular of the Cathedral of Tortosa named Francesc Marbres, a Catalan from Barcelona, while he was Master of Arts (...) at the University of Toulouse around 1330.

MutL family proteins contain an N‐terminal ATPase domain (NTD), an unstructured interdomain linker, and a C‐terminal domain (CTD), which mediates constitutive dimerization between subunits and often contains an endonuclease active site. Most MutL homologs direct strand‐specific DNA mismatch repair by cleaving the error‐containing daughter DNA strand. The strand cleavage reaction is poorly understood; however, the structure of the endonuclease active site is consistent with a two‐ or three‐metal ion cleavage mechanism. A motif required for this endonuclease activity is present in (...) the unstructured linker of Mlh1 and is conserved in all eukaryotic Mlh1 proteins, except those from metamonads, which also lack the almost absolutely conserved Mlh1 C‐terminal phenylalanine‐glutamate‐arginine‐cysteine (FERC) sequence. We hypothesize that the cysteine in the FERC sequence is autoinhibitory, as it sequesters the active site. We further hypothesize that the evolutionary co‐occurrence of the conserved linker motif with the FERC sequence indicates a functional interaction, possibly by linker motif‐mediated displacement of the inhibitory cysteine. This role is consistent with available data for interactions between the linker motif with DNA and the CTDs in the vicinity of the active site. (shrink)

Once upon a time, modal logic was castigated because it ‘had no semantics.’ Kripke, Hintikka, Kanger, and others changed all that. In a similar way, when Relevant Logic was introduced by Anderson and Belnap, it too was castigated for ‘having no semantics.’ The present overview marks a culmination of that effort. The semantic approach described here brings together a number of hitherto disparate efforts to set out formal systems for logics of relevant implication and entailment. It also makes clear (despite (...) some of our hopes and utterances) that the One True Logic does not exist. This is as true for relevant logics as Kripke et al., showed it to be for modal logics. In both cases, subtle (and not so subtle) variations on semantical postulates produce different logics in the same family. The question of which semantical postulates are correct makes no sense without further context, i.e., the questioner needs to answer the question: Correct for what? The question that does remain is: What motivates the relevant family of logics? And this is the question that is the main job for this chapter to investigate. (shrink)

This paper presents the first use of a computational model of natural logic—a system of logical inference which operates over natural language—for textual inference. Most current approaches to the PAS- CAL RTE textual inference task achieve robustness by sacrificing semantic precision; while broadly effective, they are easily confounded by ubiquitous inferences involving monotonicity. At the other extreme, systems which rely on first-order logic and theorem proving are precise, but excessively brittle. This work aims at a middle way. Our system finds (...) a low-cost edit sequence which transforms the premise into the hypothesis; learns to classify entailment relations across atomic edits; and composes atomic entailments into a top-level entailment judgment. We provide the first reported results for any system on the FraCaS test suite. We also evaluate on RTE3 data, and show that hybridizing an existing RTE system with our natural logic system yields significant performance gains. (shrink)

In this book, Christopher D. Rodkey asks how the brain worships and responds by engaging ideas from neurological science, philosophy, ritual theory, and religious education. The Synaptic Gospel will prove to be a useful theoretical tool for pastors, religious educators, youth ministers, church music professionals, and seminary students.

I wish to present a codi cation of syntactic approaches to dealing with ergative languages and argue for the correctness of one particular approach, which I will call the Inverse Grammatical Relations hypothesis.1 I presume familiarity with the term `ergativity', but, brie y, many languages have ergative case marking, such as Burushaski in (1), in contrast to the accusative case marking of Latin in (2). More generally, if we follow Dixon (1979) and use A to mark the agent-like argument of (...) a transitive verb, O to mark the patient-like argument of a transitive verb, and S to mark the single argument of an intransitive verb, then we can call ergative any subsystem of a language that groups S and O in contrast to A, as shown in (3).

Throughout, there are many case histories to illustrate the text.

This paper proposes a new architecture for textual inference in which finding a good alignment is separated from evaluating entailment. Current approaches to semantic inference in question answering and textual entailment have approximated the entailment problem as that of computing the best alignment of the hypothesis to the text, using a locally decomposable matching score. While this formulation is adequate for representing local (word-level) phenomena such as synonymy, it is incapable of representing global interactions, such as that between verb negation (...) and the addition/removal of qualifiers, which are often critical for determining entailment. We propose a pipelined approach where alignment is followed by a classification step, in which we extract features representing high-level characteristics of the entailment problem, and give the resulting feature vector to a statistical classifier trained on development data.

gloria evangelina anzaldúa has been hailed as one of most important cultural theorists of the past fifty years. Her work, especially her groundbreaking Borderlands/La Frontera: The New Mestiza, continues to animate many contemporary discourses, especially those concerned with cultural and linguistic hybridity, intersectionality, and women of color feminism. Yet one may ask: What is Anzaldúa's distinctive contribution to contemporary discourses of spirituality and religion? In a 1993 interview, Anzaldúa herself lays bare the relative inattention that critics have given to her (...) understanding of spirituality: One of the things that doesn't get talked about is the connection between body...

Future practitioners of sustainable agriculture and agroecology must have the capacity to address the wicked problems in the food system to make progress toward sustainability. Undergraduate sustainable agriculture students from a variety of backgrounds may struggle with the question, is the challenging and complex work of addressing wicked problems of agroecology for me? Our case study investigated sociocultural tensions associated with identity encountered when wicked problems teaching units were integrated into the Advanced Practices of Sustainable Agriculture course at a large, (...) Midwestern Land Grant University. The research and course employed a four-part framework that focused on attending to individual needs and identities, facilitating practice-based and community-based learning, engaging in problems situated in regional contexts, and supporting awareness of local and global political and ecological issues. Researchers used a community of practice theoretical lens, and focused on the sociocultural tensions that may have impacted individual and community identity formation. Two wicked problems teaching units are described by drawing upon documentation and audio recordings from planning meetings, course sessions, student and instructor interviews, and course artifacts. Vignettes were constructed to situate four interrelated types of sociocultural tensions encountered by instructors and students. These tensions reflected forces at the individual, community, local, and global levels which interact to influence learners’ capacity to become full participants in sustainable agriculture. The study fills a gap related to affective dimensions of learning like identity in agroecology education. Dilemmas and implications related to identity, pedagogy, and epistemology are discussed.

We present a system for deciding whether a given sentence can be inferred from text. Each sentence is represented as a directed graph (extracted from a dependency parser) in which the nodes represent words or phrases, and the links represent syntactic and semantic relationships. We develop a learned graph matching model to approximate entailment by the amount of the sentence’s semantic content which is contained in the text. We present results on the Recognizing Textual Entailment dataset (Dagan et al., 2005), (...) and show that our approach outperforms Bag- Of-Words and TF-IDF models. (shrink)

The Logic R4 is obtained by adding the axiom □ → to the modal relevant logic NR. We produce a model theory for this logic and show completeness. We also show that there is a natural embedding of a Kripke model for S4 in each R4 model structure.

We propose a model of natural language inference which identifies valid inferences by their lexical and syntactic features, without full semantic interpretation. We extend past work in natural logic, which has focused on semantic containment and monotonicity, by incorporating both semantic exclusion and implicativity. Our model decomposes an inference problem into a sequence of atomic edits linking premise to hypothesis; predicts a lexical semantic relation for each edit; propagates these relations upward through a semantic composition tree according to properties of (...) intermediate nodes; and joins the resulting semantic relations across the edit sequence. A computational implementation of the model achieves 70% accuracy and 89% precision on the FraCaS test suite. Moreover, including this model as a component in an existing system yields significant performance gains on the Recognizing Textual Entailment challenge. (shrink)

Grammatical theory has long wrestled with the fact that causative constructions exhibit properties of both single words and complex phrases. However, as Paul Kiparsky has observed, the distribution of such properties of causatives is not arbitrary: ‘construal’ phenomena such as honorification, anaphor and pronominal binding, and quantifier ‘floating’ typically behave as they would if causatives were syntactically complex, embedding constructions; whereas case marking, agreement and word order phenomena all point to the analysis of causatives as single lexical items.1 Although an (...) analysis of causatives in terms of complex syntactic structures has frequently been adopted in an attempt to simplify the mapping to semantic structure, we believe that motivating syntactic structure based on perceived semantics is questionable because in general a syntax/semantics homomorphism cannot be maintained without vitiating syntactic theory (Miller 1991). Instead, we sketch a strictly lexical theory of Japanese causatives that deals with the evidence offered for a complex phrasal analysis. Such an analysis makes the phonology, morphology and syntax parallel, while a mismatch occurs with the semantics. The conclusions we will reach are given in (1). (shrink)

Christopher Frith is a research professor at the Functional Imaging Laboratory of the Wellcome Department of Imaging Neuroscience at University College, London. He explores, experimentally, using the techniques of functional brain imaging, the relationship between human consciousness and the brain. His research focuses on questions pertaining to perception, attention, control of action, free will, and awareness of our own mental states and those of others. As the following discussion makes clear, Frith investigates brain systems involved in the choice of (...) one action over another and in the understanding of other people. Such investigations are aimed at understanding brain basis of autism and schizophrenia. In his widely cited study of schizophrenia, The Cognitive Neuropsychology of Schizophrenia , Frith argues that many of the positive symptoms of schizophrenia, such as delusions of control, auditory hallucinations, and thought insertion, involve problems of self-monitoring. Patients, in effect, lose track of their own intentions and mistakenly attribute agency for their own actions to someone else. Frith employs models of motor control, involving comparator mechanisms and efference copy, not only to explain delusions that involve movement, but also to develop a neurocognitive explanation of delusional cognition.

This is Part II of a two-part study on the questions on Aristotles’ Physics by Francesc Marbres, the artist commonly known as “John the Canon.” Although written around 1330, only two fourteenth-century manuscripts preserve the work, but it became so popular around 1450 that dozens of fifteenth-century manuscripts containing the work survive and it was printed eight times from 1475 to 1520. Here the manuscripts and early prints are described, and then an attempt is made to trace the tradition of (...) the text using structural differences, the colophons and variant readings in the question-titles and small passages. These three sets of data turn out to be insufficient for constructing a stemma; instead they provide evidence of extensive contamination, suggesting that many scribes and printers employed more than one witness. This conclusion reinforces what we learn from marginalia and from information about the Oxford curriculum: the questions on the Physics by the mysterious “John the Canon” played an active rol...
