The discourses of agricultural extension reveal how actors represent their scientific activities and goals. The “transfer of technology” discourse developed with the professional U.S. extension service, reproducing its expert/lay power relations. Agroecology is emerging as a systems approach to preventing agricultural pollution. Its theoreticians argue that agroecology cannot be transferred like technology but must be extended through networks of participatory social learning. In California, hundreds of actors and dozens of institutions have cocreated agroecological partnerships using this alternative extension model. They (...) have developed three alternative extension discourses to represent and explain their activities. Bruno Latour's “circulatory system of science” model provides a superior theoretical framework for interpreting the participation and discourses of diverse actors in this extension practice.

Patents for genetic material in theindustrialized North have expandedsignificantly over the past twenty years,playing a crucial role in the currentconfiguration of the agricultural biotechnologyindustries, and raising significant ethicalissues. Patents have been claimed for genes,gene sequences, engineered crop species, andthe technical processes to engineer them. Mostcritics have addressed the human and ecosystemhealth implications of genetically engineeredcrops, but these broad patents raise economicissues as well. The Catholic social teachingtradition offers guidelines for critiquing theeconomic implications of this new patentregime. The Catholic principle of (...) the universaldestination of goods implies that genes, genesequences, and engineered crop varieties areineligible for patent protection, although theprocesses to engineer these should be eligible.Religious leaders are likely to make a moresubstantive contribution to debates aboutagricultural biotechnology by addressing theselife patents than by speculating that geneticengineering is ``playing God.''''.

THIS ESSAY SEEKS TO REDRESS THE SHORTCOMINGS OF CHRISTIAN ENVIronmental ethics by proposing Franciscan environmental ethics drawn from the affective and embodied experience of Francis of Assisi plus the Franciscan theological tradition that he inspired, as exemplified by Bonaventure and John Duns Scotus. Drawing its inspiration from the love Francis of Assisi had for nature, the Franciscan tradition holds that creation bursts with religious significance. This tradition interprets Francis' affective and direct sensory experience of the natural world with theological concepts (...) creatively reworked from scripture and patristic sources, especially the Incarnation and theTrinity.The Franciscan understanding of the Incarnation emphasizes continuity between humanity, creatures, and elements. The Franciscan vision of Trinity as community-ofpersons, inspired by Francis's Canticle of Creatures, supports a more inclusive vision of the moral community. Franciscan environmental ethics can inspire an enhanced moral imagination and the praxis of an ethic of care. (shrink)

Drawing from a four-year study of US science institutions that support biological control of arthropods, this article examines the decline in biological control institutional capacity in California within the context of both declining public interest science and declining agricultural research activism. After explaining how debates over the public interest character of biological control science have shaped institutions in California, we use scientometric methods to assess the present status and trends in biological control programs within both the University of California Land (...) Grant System and the California Department of Food and Agriculture. We present available data on the number of scientific positions and the types of positions to discuss the impact on the amount of public interest research on biological control in California. We use sociograms to depict how biological control science networks have been reconfigured over time. Our quantitative and qualitative analyses indicate that the following factors contributed to the decline of biological control science in California over the 45-year period analyzed: (1) the institutional reconfiguration of university research priorities; (2) the fraying networks within and increasing specialization of biological control science; (3) the transformation of the social organization of the life science work, including privatization; and (4) the abandonment of this thematic area by civil society activist groups. This broad array of forces suggests that biological control, as a public interest science, will require a deliberate intervention, based on advocacy of clear public interest criteria. (shrink)

This book builds on the idea that pragmatics and philosophy are strictly interconnected and that advances in one area will generate consequential advantages in the other area. The first part of the book, entitled ‘Theoretical Approaches to Philosophy of Language’, contains contributions by philosophers of language on connectives, intensional contexts, demonstratives, subsententials, and implicit indirect reports. The second part, ‘Pragmatics in Discourse’, presents contributions that are more empirically based or of a more applicative nature and that deal with the pragmatics (...) of discourse, argumentation, pragmatics and law, and context. The book presents perspectives which, generally, make most of the Gricean idea of the centrality of a speaker’s intention in attribution of meaning to utterances, whether one is interested in the level of sentence-like units or larger chunks of discourse.

National water quality concerns are creating momentum for legislation that takes a proactive stance toward agricultural practices involving agrichemicals. In response, the Environmental Protection Agency has asked the states to design appropriate non-point source pollution policies. This article examines the issues involved in two ways. First, it reviews the literature on previous conservation policies and discusses the implications for stricter regulation. Second, in order to determine the public opinion context for non-point source pollution policies, it examines the responses of a (...) sample of Oklahoma rural leaders to a set of environmental, water quality, political, economic, and family farm orientation items developed in previous surveys. The analysis considers areas of agreement and disagreement related to socio-economic status, education, and extent of involvement in farming. It concludes that although Oklahoma's rural leaders are concerned about water quality problems, an environmentally-sound formulation of rural values has yet to develop. The most serious obstacle appears to be the perceived threat of environmental regulations to the variability of production agriculture. (shrink)

H.P. Grice is known principally for his influential contributions to the philosophy of language, but his work also includes treatises on the philosophy of mind, ethics, and metaphysics--much of which is unpublished to date. This collection of original essays by such philosophers as Nancy Cartwright, Donald Davidson, Gilbert Harman, and P.F. Strawson demonstrates the unified and powerful character of Grice's thoughts on being, mind, meaning, and morals. An introductory essay by the editors provides the first overview of Grice's work.

A successful lexicographic semantic description characterizes the concepts that occur in establishing the meaning of a listeme by modelling what the competent native-like speaker of the language knows. Because concepts can only be identified to another human through the medium of a natural language, the metalanguage used in the semantic definition of a natural language expression in the object language will always be equivalent to the natural language expression through which that metalanguage is interpreted. The metalanguage of a semantic theory (...) is a demonstrably rational abstract model developed by applying the analyst’s experience and intuitions to inferences drawn from occurrences of actual speech events. Each sense of a listeme is characterized by a description of the salient properties of its typical denotatum. To most effectively implement this project in conceptual engineering is to capture every possible sense of the listeme using metalanguage that is at the same time precise, comprehensive, and succinct. A review of several proposed lexicon/dictionary entries for the listeme cup reveals lacunae that are rectified in a decision procedure whose output characterizes the relevant sense of the input listeme using natural language and the procedural constructs/commands &, XOR, IF, ELSE, ELIF, GOTO, OUTPUT, TENABLE, NEXT ITEM. The resulting lexicographic semantic description satisfies the specified success condition. Establishing the characteristics of metalanguage is crucial to the proper investigation of conceptual engineering. (shrink)

The preceding two sections have considered, respectively, the discreditation of psychological belief, and of propositional belief, which begins with the claim that a belief possessed by some person is non-epistemically explicable and ends with the claim that that person is unreasonable or that that belief is (probably) false. Obviously, only certain strategies of discreditation were discussed, and those only partially. But if the examples of discrediting strategies were representative, and the remarks made about them were correct, what, if anything, follows?It (...) seems clear that the sheer fact that a person's belief is non-epistemically explicable entails very little if anything about the person's reasonability in holding it or the probable falsehood of the belief in question. Nor does the fact that a basic belief is held without reason or grounds seem to speak against the rationality of its believer - not at least with respect to the sort of propositions we called structural. It does not follow that one cannot rationally assess competing structural beliefs - that is another, and given the present argument an entirely open, question. It does seem correct that the more restrictive axioms of the ethics of properly held basic beliefs are ill-suited to deal responsibly with the acceptance of structural propositions. And at least some religious propositions - God exists among them - seem to me to be of that sort. Of course, that raises the question of what, exactly, a structural proposition is - which, again, is another topic.If the argument of this essay is correct, the shift from considering whether some particular (and perhaps idiosyncratic) person is reasonable in accepting some proposition, in cases where this is an interesting and debateable matter, to whether (on the whole) this proposition is one that can be accepted without rendering oneself unreasonable, seems to be an issue usually not capable of rational resolution without engaging in some sort of direct assessment of the proposition believed, and the strategy of trying to escape this by considering whether a person's acceptance of that proposition can be non-epistemically explained seems, on the whole, not a profitable enterprise. Further, often, at least, it can be countered in one or another of the ways we considered in the preceding two sections. So I am inclined to view the attempt to settle interesting debates about whether a person is reasonable in accepting a proposition by arguing that his acceptance is non-epistemically explicable as, on the whole, a failure.If anything, things are worse, so far as I can see, for attempts to argue from the fact that a person's belief is non-epistemically explicable to the conclusion that it is probably false. For, again, this argument has force only if the fact that this person's acceptance of it is non-epistemically explicable is not idiosyncratic, and this is establishable, often at least, only by appealing to the results of a direct assessment of the proposition believed (or by offering a judgment on this matter without benefit of any assessment, which of course is worthless). Nor, of course, is the nonepistemic explicability of a person's belief that P sufficient to discredit the person, let alone P, and the sorts of properties that are often alleged to accompany non-epistemically explicable beliefs seem either in fact not to accompany them, or to accompany only a basically irrelevant and uninteresting sub-set of them, or not to be such as to make falsehood of the propositions whose belief they accompany probable.A final comment These remarks, at best, scratch the surface of a difficult and complex topic. It is a topic on which, so far as I am aware, not a great deal has been written. My hope is that what I have said here may stimulate sufficient interest in the topic for others to provide a further exploration of the issues that I have here only been able to highlight. (shrink)

Since argument frames precede most other arguing processes, argument editing among them, one’s frames may well predict one’s preferred editorial standards. This experiment assesses people’s arguing frames, gives them arguments to edit, and tests whether the frames actually do predict editorial preferences. Modest relationships between argument frames and argument editing appear. Other connections among frames, editing, and additional individual differences variables are more substantial. Particularly notable are the informative influences of psychological reactance. A new theoretical contribution is offered, connecting argument (...) frame research to Erving Goffman’s frame analysis.

Republican freedom is freedom from domination juxtaposed to negative freedom as freedom from interference. Proponents argue that republican freedom is superior since it highlights that individuals lose freedoms even when they are not subject to interference, and claim republican freedom is more ‘resilient’. Republican freedom is trivalent, that is, it includes the idea that someone might be non-free to perform some actions rather than unfree, and in that sense everyone regards republican freedom as different from negative freedom. Trivalence makes republican (...) freedom moralized according to negative libertarians. Beyond that, negative libertarians argue that all the supposed advantages of republican freedom are compatible with those of pure negative-freedom measures. That is, losses and gains of republican freedom are captured in measures of pure negative freedom, and any protection for republican freedom also protects negative freedom, ensuring each is equally resilient. Since republican freedom has no advantages over negative freedom, but has other problems (is moralized and is trivalent), negative freedom is superior. I examine this debate in this article through the ‘coalition problem’ for republican freedom. The coalition problem is that since there is always a coalition of others who could dominate any agent in any sphere, all agents are subject to domination, and hence no one can ever have republican freedom. Pettit’s simple solution to this reductio ad absurdum distinguishes potential from actual coalitions. Individuals are only dominated by actual coalitions, and not by potential ones. The simple solution highlights moralization problems as it demonstrates that domination cannot be purely institutionally defined, but requires consideration of dispositions and expectations about others’ behaviour. I argue that the differences between the ‘free man’ and ‘unfree person’ paradigmatic to republican arguments is best captured not by the difference between domination and interference, but, rather, from familiar distinctions between different types of rights and freedoms. Resilience is a practical matter that might track some of these familiar distinctions. (shrink)

Egalitarians claim that inequality in society is only justified to the extent that it results from choices freely and responsibly made. Inequality resulting from brute bad luck is not justified. I argue that luck, and therefore responsibility, are defined in terms of the reward structure. Luck and responsibility are epiphenomena of the incentives that people have to choose from the opportunity sets available. To that end egalitarians should look more directly at the degree of inequality that is acceptable and examine (...) more closely the classes of actions they want to leave to individual responsibility even though these will lead to greater inequality. State action should concentrate upon reducing inequality between classes of people; it cannot be expected to reduce all inequalities between people even though many of these will have only peripheral relationships to responsibility.

Although neural encoding by bats and owls presents seductive analogies, the major contribution of locus equations and orderly output constraints discussed by Sussman et al. is the demonstration that important acoustic information for speech perception can be captured by elegant and neurally-plausible learning processes.

A funny thing happened to Cartesian dualism on the way to the twenty-first century. After three hundred-odd years the irreconcilable dualism between `mind' and `matter' is still with us but, especially since the 1950s it has undergone a startling change. Matter has gotten fatter while mind is hard to find. I refer in particular to the domain of thought which has been transferred from res cogitans to res extensa in the guise of the computational brain. For Descartes, the body was (...) an automaton motivated by purely material forces to which the thinking mind was completely inessential . Now, however, the thinking mind has become the neural processor which is part of the same automaton. The only vestige of res cogitans which remains is sentience , i.e. conscious awareness. Thought is represented in sentience by what might be called `thought experience', i.e. the wispy but cognitively irrelevant stuff that takes place behind our foreheads. The rest of consciousness is made up of such things as sights, sounds, smells, tastes, elations, depressions, agonies and ecstasies -- our qualia. Some cognitive scientists deny we have qualia; they say we only seem to have them. But even those who admit we have them are increasingly inclined to follow their famous French predecessor and declare consciousness irrelevant to physical information processing. The latest doctrine of this persuasion is conscious inessentialism which is defined by Owen Flanagan as the view that `for any intelligent activity i, performed in any cognitive domain d, even if we do i with conscious accompaniments, i can in principle be done without these conscious accompaniments'.

In the final third of his paper, Pailthorp proposes the following analysis of knowledge.

Harry G. Frankfurt has presented a case of a counterfactual intervener CI with knowledge and power to control an agent so he will do A. He concludes that if the agent prefers to do A and there is no intervention by CI, the agent has acted of his own free will and is morally responsible for doing A, though he lacked an alternative possibility. I consider the consequences for freedom and moral responsibility of CI having a complete plan P for (...) all actions of an agent, Lucky, who luckily has preferences that accord with P, and I extend the argument to all citizens of a land, Luckyland, who are like Lucky. I argue the citizens of Luckyland have free will but lack moral responsibility because of the connection between moral responsibility, reactive attitudes and future action. Furthermore, the presence of CI and his plan P may allow free will but is incompatible with freedom of preference. Preference concerns alternatives excluded by CI. I argue that a special higher order preference for the preference structure, a power preference, ends the regress of higher order preference and explains the first order preference. Causal determinism is compatible with freedom of preference explained by a power preference when a power preference would also explain an alternative preference. The remoteness argument for incompatibility fails because of a lack of transitivity causal explanation. The power preference is the self-explained source of freedom of preference. That basic freedom may be limited by government knowledge of our preferences, even if, like Lucky, our preferences do not provoke intervention and we conform of our own free will. (shrink)

Ecophilosophers have long argued that addressing the environmental crisis not only demands reassessing the ethical aspects of human and nature relations, but also prevailing theories of human nature. Philosophical anthropology has historically taken this as its calling, and its resources may be profitably utilized in the context of ecophilosophy. Distinguishing between conservative and emancipatory naturalism leads to a critical discussion of the Cartesian culture/nature dualism. Marjorie Grene is discussed as a resource in the tradition of philosophical anthropology which enables us (...) to avoid dualistic thinking and espouse an emancipatory naturalism by resisting reductionism and acknowledging the diffuse dependence of human being on natural processes. In order to fully explicate the conditions of human dependence upon nature it becomes necessary to define an appropriate approach to ontology. This critical ontology facilitates a stratified understanding of the place of humans in nature without lapsing into reductivism or post-Kantian constructivism. It provides a sounder basis than either alternative for motivating a many- sided ecophilosophical perspective on human being. (shrink)

In Imagination, Jim Davies explains that most humans have mental imagery: an ability to make pictures in the mind without immediate perceptual input-as we do when we dream. Davies writes programs that enable computers to do something similar. Given a few words of description, a computer can generate pictures with several objects arranged in appropriate ways. Jonathan Gilmore’s Apt Imaginings is about whether engagement in works of fiction is continuous or discontinuous with how we deal with people and objects in (...) everyday life. He argues for discontinuity. In constructing a critical framework within which to evaluate these two books, I use Kenneth Craik’s theory of mental models. Craik’s theory enables us to understand how we humans have evolved to imagine possible futures, to plan and to act in relation to them, and also to imagine what might be going on in other people’s minds.

There are those philosophers and historians of science who claim that the acceptance and rejection of scientific theories is underdetermined by experimental results. They conclude that there is no rational method for deciding such matters solely on the basis of empirical information. The acceptance and rejection of scientific theories depends on social influence and is settled by social dominance. This I call the dominance thesis. There are also those who hold, on the contrary, that the acceptance and rejection of theories (...) in science is based solely on empirical information according to a rational method. They conclude that the acceptance and rejection of scientific theories is fully determined by experimental results. This I call the experimentalism thesis. The dominance thesis and the experimentalism thesis are both false. Both share a common premise, to wit, that empirical information is limited to experimental results. There is, however, another source of empirical information, the opinions of experts. When such social information is properly aggregated, the acceptance and rejection of scientific theories, though underdetermined by experimental results, is fully determined by the total information available.

In this article, I shed new light on a misunderstood aspect of Heraclitus’ style. The opposites employed by Heraclitus are often of equal status except that one member of each pair may also appear as a designation for the encompassing whole. I begin by discussing two interpretations of this phenomenon, which were put forward by Roman Dilcher and Alexander Mourelatos. The phenomenon is, I suggest, better understood as being an example of what is known as markedness neutralisation. I argue that (...) this phenomenon should be interpreted as further undermining what Mourelatos identified as a naïve paratactic metaphysics of mere things (NMT), to which Heraclitus was reacting by beginning to develop a hypotactic metaphysics of hierarchies and dependencies as part of a view of the world as being logos-textured. Further, I consider a series of three problems that were put forward by Dilcher, which he thinks must be addressed by anyone who claims that Heraclitus held a unity of opposites thesis. I also consider some related issues, and provide some responses. (shrink)

The aim of this book is to set a limit to thought, or rather - not to thought, but to the expression of thoughts: for in order to be able to set a limit to thought, we should have to find both sides of the limit thinkable.

Why History? is a compelling introduction to the issue of history and ethics. Designed to provoke discussion, the book asks whether and why a good knowledge and understanding of the past is desirable. In the context of current postmodern thinking, Keith Jenkins suggests that the goal of "learning lessons from the past" actually means learning lessons from stories written by historians and others. If the past as history has no foundation, can anything ethical be gained from history? Daring and (...) controversial, Why History? presents liberating challenges to history and ethics, proposing that we have reached an emancipatory moment which is well beyond the "end of history.".
