Ambitious targets to reduce greenhouse gas emissions from agriculture have been set by both national governments and their respective livestock sectors. We hypothesize that farmer self-identity influences their assessment of climate change and their willingness to implement measures which address the issue. Perceptions of climate change were determined from 286 beef/sheep farmers and evaluated using principal component analysis. The analysis elicits two components which evaluate identity, and two components which evaluate behavioral capacity to adopt mitigation and adaptation measures. Subsequent Cluster (...) Analyses reveal four farmer types based on the PCA scores. ‘The Productivist’ and ‘The Countryside Steward’ portray low levels of awareness of climate change, but differ in their motivation to adopt pro-environmental behavior. Conversely, both ‘The Environmentalist’ and ‘The Dejected’ score higher in their awareness of the issue. In addition, ‘The Dejected’ holds a high sense of perceived risk; however, their awareness is not conflated with an explicit understanding of agricultural GHG sources. With the exception of ‘The Environmentalist’, there is an evident disconnect between perceptions of agricultural emission sources and their contribution towards GHG emissions amongst all types. If such linkages are not conceptualized, it is unlikely that behavioral capacities will be realized. Effective communication channels which encourage action should target farmers based on the groupings depicted. Therefore, understanding farmer types through the constructs used in this study can facilitate effective and tailored policy development and implementation. (shrink)

The 2011 Thai general election was seen by many Thai political analysts as a watershed moment that would hopefully be the tipping point of socio-political reconciliation in the drawn out political struggle that has characterized Thai politics since 2005. The highly contested nature of Thai politics becomes salient when viewing campaign posters pictorial and linguistic content. The most controversial of which was the ``Vote No'' campaign taken on by the For Heaven and Earth Party, which is a political party nominally (...) associated with Thailand's conservative People's Alliance for Democracy. This study seeks to unwrap and decode the semiotics of this party's political campaign posters in Thailand's 2011 general election by providing cultural context to the application of multimodal discourse analysis and critical semiotics framework. I will argue that the ``Vote No'' campaign and its campaign posters depicting politicians as animals is a continuing political discourse of conservative Buddhist philosophers/scholars that reaches back to the 1980s. Furthermore, the ``Vote No'' campaign seeks to create dissonance and reinstate conservative rule via monarchial and/or military intervention by creating political deadlock thereby undermining democratic rights and rule by the exercising of democratic rights of voting, thus disenfranchising citizens by their own hand.

Nurses have moral obligations incurred by membership in the profession to participate knowingly in health policy advocacy. Many barriers have historically hindered nurses from realizing their potential to advance health policy. The contemporary political context sets additional challenges to policy work due to polarization and conflict. Nursing education can help nurses recognize their role in advancing health through political advocacy in a manner that is consistent with disciplinary knowledge and ethical responsibilities. In this paper, the authors describe an exemplar of (...) Elizabeth Barrett's “Power as Knowing Participation in Change” theory as a disciplinary lens within a doctoral nursing health policy course. Barrett (radically) emphasizes “power as freedom” instead of “power as control.” This approach is congruent with nursing disciplinary values and enhances awareness of personal freedom and building collaborative relationships in the policy process. The theory was used in concert with other traditional policy content and frameworks from nursing and other disciplines. We discuss the role of nursing ethics viewed as professional responsibility for policy action, an overview of Barrett's theory, and the design of the course. Four student reflections on how the course influenced their thinking about policy advocacy are included. While not specific to policymaking, Barrett's theory provides a disciplinary grounding to increase students' awareness of freedom and choices in political advocacy participation. Our experience suggests that Barrett's work can be fruitful for enhancing nurses' awareness of choices to participate in change across settings. (shrink)

The 1970s were marked by a resurgence of interest in the enigmatic figure known as Pseudo-Dionysius the Aeropagite. Yet the accessibility of his works, in readable and accurate translations, continues to be a problem. Jones's translation is therefore welcome.

This study’s objective was to understand Colombian adolescents’ experiences and preferences regarding access to sexual and reproductive health services (SRHS), either alone or accompanied. A mixed-method approach was used, involving a survey of 812 participants aged eleven to twenty-four years old and forty-five semi-structured interviews with participants aged fourteen to twenty-three. Previous research shows that adolescents prefer privacy when accessing SRHS and often do not want their parents involved. Such findings align with the longstanding tendency to frame the ethical principle (...) of autonomy as based on independence in decision-making. However, the present study shows that such a conceptualization and application of autonomy does not adequately explain Colombian adolescent participants’ preferences regarding access to SRHS. Participants shared a variety of preferences to access SRHS, with the majority of participants attaching great importance to having their parents involved, to varying degrees. What emerges is a more complex and non-homogenous conceptualization of autonomy that is not inherently grounded in independence from parental involvement in access to care. We thus argue that when developing policies involving adolescents, policymakers and health professionals should adopt a nuanced “relational autonomy” approach to better respect the myriad of preferences that Colombian (and other) adolescents may have regarding their access to SRHS.

A HISTORY OF WESTERN PHILOSOPHY examines the nature of philosophical enterprise and philosophy's role in Western culture. Jones and Fogelin weave key passages from classic philosophy works into their comments and criticisms, giving A HISTORY OF WESTERN PHILOSOPHY the combined advantages of a source book and textbook. The text concentrates on major figures in each historical period, combining exposition with direct quotations from the philosophers themselves. The text places philosophers in appropriate cultural context and shows how their theories reflect (...) the concerns of their times. (shrink)

Agriculture plays a key role in national economies and individual livelihoods in many developing countries, and yet agriculture as a field of study and an occupation remain under-emphasized in many educational systems. In addition, working in agriculture is often perceived as being less desirable than other fields, and not a viable or compelling option for students who have received a post-secondary education. This article explores the historical and contemporary perceptions of agriculture as a field of study and an occupation globally, (...) and applies themes from the literature to analyze primary data from focus groups with international students studying for university degrees in the United States. The article analyzes students’ perceptions and experiences in four countries—Bangladesh, Nepal, Honduras and Haiti—in order to make recommendations about how best to address challenges and develop capacity in agricultural education and employment in low-income countries.

Central to discussion of supervaluationist accounts of vagueness is the extent to which they require revisions of classical logic and if so, whether those revisions are objectionable. In an important recent Journal of Philosophy article, J.R.G. Williams presents a powerful challenge to the orthodox view that supervaluationism is objectionably revisionary. Williams argues both that supervaluationism is non-revisionary and that even if it were, those revisions would be unobjectionable. This note shows that his arguments for both claims fail.

William Sweet gathers responses to the major writings of the leading figures of the British idealist movement, including contributions by Bertrand Russell, John Dewey, Sir Ernest Barker, Sir Henry Jones, R.F.A. Hoernle, J.S. MacKenzie, Brand Blanshard and others.

It is argued that "a's statement, That x is eligible, Is true" says, And not merely presupposes as williams holds, That x is eligible. A brief summary is given of williams' analysis of what is said about a statement when it is said to be true. An attempt is made to show that the predicable in williams' definition is anomalous by contrasting it with genuine conjunctive predicables. Finally, It is suggested that williams' predicable, Even if suitably modified, Would not be (...) the formal equivalent of "things are as a says they are", Which is what williams had claimed.

This book examines the effects of the market mechanism on economies and societies. It argues that perfect competition has a tendency to promote adulteration of products and a general deterioration in quality. It also contends that it is very difficult for competitive firms to behave in socially desirable ways - being kind to the environment, contributing to worthy social programmes, handling redundancy humanely. The book goes on to propose ways in which these flaws might be remedied without subverting the market (...) mechanism. (shrink)

This essay re-examines Meinong's "Über Gegenstandstheorie" and undertakes a clarification and revision of it that is faithful to Meinong, overcomes the various objections to his theory, and is capable of offering solutions to various problems in philosophy of mind and philosophy of language. I then turn to a discussion of a historically and technically interesting Russell-style paradox (now known as "Clark's Paradox") that arises in the modified theory. I also examine the alternative Meinong-inspired theories of Hector-Neri Castañeda and Terence Parsons.

This essay considers what it means to understand natural language and whether a computer running an artificial-intelligence program designed to understand natural language does in fact do so. It is argued that a certain kind of semantics is needed to understand natural language, that this kind of semantics is mere symbol manipulation (i.e., syntax), and that, hence, it is available to AI systems. Recent arguments by Searle and Dretske to the effect that computers cannot understand natural language are discussed, and (...) a prototype natural-language-understanding system is presented as an illustration.

"This book, one of the most frequently cited works on Martin Heidegger in any language, belongs on any short list of classic studies of Continental philosophy. William J. Richardson explores the famous turn in Heidegger's thought after Being in Time and demonstrates how this transformation was radical without amounting to a simple contradiction of his earlier views." "In a full account of the evolution of Heidegger's work as a whole, Richardson provides a detailed, systematic, and illuminating account of both (...) divergences and fundamental continuities in Heidegger's philosophy, especially in light of recently published works. He demonstrates that the "thinking" of Being for the later Heidegger has exactly the same configuration as the radical phenomenology of the early Heidegger, once he has passed through the "turning" of his way." Including as a preface the letter that Heidegger wrote to Richardson and a new writer's preface and epilogue, the new edition of this valuable guide will be an essential resource for students and scholars for many years to come.

There are many branches of philosophy called “the philosophy of X,” where X = disciplines ranging from history to physics. The philosophy of artificial intelligence has a long history, and there are many courses and texts with that title. Surprisingly, the philosophy of computer science is not nearly as well-developed. This article proposes topics that might constitute the philosophy of computer science and describes a course covering those topics, along with suggested readings and assignments.

In this reply to James H. Fetzer’s “Minds and Machines: Limits to Simulations of Thought and Action”, I argue that computationalism should not be the view that (human) cognition is computation, but that it should be the view that cognition (simpliciter) is computable. It follows that computationalism can be true even if (human) cognition is not the result of computations in the brain. I also argue that, if semiotic systems are systems that interpret signs, then both humans and computers are (...) semiotic systems. Finally, I suggest that minds can be considered as virtual machines implemented in certain semiotic systems, primarily the brain, but also AI computers. In doing so, I take issue with Fetzer’s arguments to the contrary. (shrink)

John Searle once said: "The Chinese room shows what we knew all along: syntax by itself is not sufficient for semantics. (Does anyone actually deny this point, I mean straight out? Is anyone actually willing to say, straight out, that they think that syntax, in the sense of formal symbols, is really the same as semantic content, in the sense of meanings, thought contents, understanding, etc.?)." I say: "Yes". Stuart C. Shapiro has said: "Does that make any sense? Yes: Everything (...) makes sense. The question is: What sense does it make?" This essay explores what sense it makes to say that syntax by itself is sufficient for semantics. (shrink)

What implications, if any, does evolutionary biology have for metaethics? Many believe that our evolutionary background supports a deflationary metaethics, providing a basis at least for debunking ethical realism. Some arguments for this conclusion appeal to claims about the etiology of the mental capacities we employ in ethical judgment, while others appeal to the etiology of the content of our moral beliefs. In both cases the debunkers’ claim is that the causal roles played by evolutionary factors raise deep epistemic problems (...) for realism: if ethical truths are objective or independent of our evaluative attitudes, as realists maintain, then we lose our justification for our ethical beliefs once we become aware of the evolutionary shaping of our ethical capacities or beliefs, which would not have disposed us reliably to track independent ethical truths; realism, they claim, thus saddles us with ethical skepticism. I distinguish and spell out various evolutionary debunking arguments along these lines and argue that they all fail: the capacity etiology argument fails to raise any special or serious problem for realism, and the content etiology arguments all rely on strong explanatory claims about our moral beliefs that are simply not supported by the science unless it is supplemented by philosophical claims that just beg the question against realism from the start. While the various debunking arguments do bring out some interesting commitments of ethical realism, and even raise some good challenges as realists develop positive moral epistemologies, they fall far short of their debunking ambitions.

Review of Joseph Y. Halpern (ed.), Theoretical Aspects of Reasoning About Knowledge: Proceedings of the 1986 Conference (Los Altos, CA: Morgan Kaufmann, 1986),.

This essay continues my investigation of `syntactic semantics': the theory that, pace Searle's Chinese-Room Argument, syntax does suffice for semantics (in particular, for the semantics needed for a computational cognitive theory of natural-language understanding). Here, I argue that syntactic semantics (which is internal and first-person) is what has been called a conceptual-role semantics: The meaning of any expression is the role that it plays in the complete system of expressions. Such a `narrow', conceptual-role semantics is the appropriate sort of semantics (...) to account (from an `internal', or first-person perspective) for how a cognitive agent understands language. Some have argued for the primacy of external, or `wide', semantics, while others have argued for a two-factor analysis. But, although two factors can be specified–-one internal and first-person, the other only specifiable in an external, third-person way–-only the internal, first-person one is needed for understanding how someone understands. A truth-conditional semantics can still be provided, but only from a third-person perspective. (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)

A critique of several recent objections to John Searle's Chinese-Room Argument against the possibility of "strong AI" is presented. The objections are found to miss the point, and a stronger argument against Searle is presented, based on a distinction between "syntactic" and "semantic" understanding.

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)

A critical survey of some attempts to define ‘computer’, beginning with some informal ones, then critically evaluating those of three philosophers, and concluding with an examination of whether the brain and the universe are computers.

Philosophy has been characterized (e.g., by Benson Mates) as a field whose problems are unsolvable. This has often been taken to mean that there can be no progress in philosophy as there is in mathematics or science. The nature of problems and solutions is considered, and it is argued that solutions are always parts of theories, hence that acceptance of a solution requires commitment to a theory (as suggested by William Perry's scheme of cognitive development). Progress can be had (...) in philosophy in the same way as in mathematics and science by knowing what commitments are needed for solutions. Similar views of Rescher and Castañeda are discussed.

The proper treatment of computationalism, as the thesis that cognition is computable, is presented and defended. Some arguments of James H. Fetzer against computationalism are examined and found wanting, and his positive theory of minds as semiotic systems is shown to be consistent with computationalism. An objection is raised to an argument of Selmer Bringsjord against one strand of computationalism, namely, that Turing-Test± passing artifacts are persons, it is argued that, whether or not this objection holds, such artifacts will inevitably (...) be persons.

I advocate a theory of syntactic semantics as a way of understanding how computers can think (and how the Chinese-Room-Argument objection to the Turing Test can be overcome): (1) Semantics, considered as the study of relations between symbols and meanings, can be turned into syntax – a study of relations among symbols (including meanings) – and hence syntax (i.e., symbol manipulation) can suffice for the semantical enterprise (contra Searle). (2) Semantics, considered as the process of understanding one domain (by modeling (...) it) in terms of another, can be viewed recursively: The base case of semantic understanding –understanding a domain in terms of itself – is syntactic understanding. (3) An internal (or narrow ), first-person point of view makes an external (or wide ), third-person point of view otiose for purposes of understanding cognition. (shrink)
