The ecologist today finds scarce ground safe from controversy. Decisions must be made about what combination of data, goals, methods, and theories offers them the foundations and tools they need to construct and defend their research. When push comes to shove, ecologists often turn to philosophy to justify why it is their approach that is scientific. Karl Popper’s image of science as bold conjectures and heroic refutations is routinely enlisted to justify testing hypotheses over merely confirming them. One of the (...) most controversial theories in contemporary science is the Neutral Theory of Ecology. Its chief developer and proponent, Stephen Hubbell, presents the neutral theory as a bold conjecture that has so far escaped refutation. Critics of the neutral theory claim that it already stands refuted, despite what the dogmatic neutralists say. We see the controversy through a Popperian lens. But Popper’s is an impoverished philosophy of science that distorts contemporary ecology. -/- The controversy surrounding the neutral theory actually rests on a methodological fault. There is a strong but messy historical link between the concepts of being neutral and being null in biology, and Hubbell perpetuates this when he claims that the neutral theory is supplies the appropriate null for testing alternative theories. What method is being followed here? There are three contenders: -/- Null hypothesis testing tests for whether a there is a pattern to be explained. Null modeling tests for whether a process is causally relevant to a pattern. Baseline modeling apportions relative responsibility to multiple processes each relevant to a pattern. -/- Whether the neutral theory supplies an appropriate “null” depends upon whether null hypothesis, null modeling, or baseline model is intended. These methods prescribe distinct inference patterns. If they are null hypothesis testing or null modeling, the neutralists’s reasoning is invalid. If they are baseline modeling, the justification of a crucial assumption remains opaque. Either way, the neutral-null connection is being exploited rhetorically to privilege the neutral theory over its rivals. Clarifying the reasoning immunizes us against the rhetoric and foregrounds the underlying virtues of the neutralist approach to ecology. -/- The Popperian lens distorts theoretical development as dogmatism. Lakatos’s view of science as the development of research programmes clarifies the epistemology of the neutral theory. Focusing philosophical attention on the neutralist research programme illuminates (1) the synchronic uses of the neutral theory to make predictions and give descriptions and explanations; (2) its diachronic development in response to theoretical innovation and confrontation with data; (3) its complex relationships to alternative theories. For example, baseline modeling is now seen to be its primary explanatory heuristic. The justification for baseline modeling with the neutral theory, previously hidden from view, is seen in the logic of in the neutralist research programme. (shrink)

Experimental natural philosophy was a mid-seventeenth-century development in which physical enquiry proceeded by connecting phenomena in an experimentally guided fashion, as opposed to attempting to account for them in terms of some underlying micro-corpuscular structure. The approach proved fruitful in two areas: Boyle’s experiments on the air pump and Newton’s experiments on the prism. This chapter argues that Lockean empiricism, which was subsequently taken to embody the principles behind Newtonianism, was an outcome of these developments and that it was worked (...) into an epistemological doctrine only when Locke encountered Malebranche’s vindication of the sole legitimacy of micro-corpuscularian explanation. The chapter reveals a form of empiricism—empiricism as a successor to, and refinement of, seventeenth-century experimental natural philosophy—which is intimately tied up with natural-philosophical practice, and is quite distinct from the speculative epistemology to which it is reduced in the rationalism and empiricism debates.

Since the heyday of ordinary language philosophy, Anglophone epistemologists have devoted a great deal of attention to the English word ‘know’ and to English sentences used to attribute knowledge. Even today, many epistemologists, including contextualists and subject-sensitive invariantists are concerned with the truth conditions of “S knows that p,” or the proposition it expresses. In all of this literature, the method of cases is used, where a situation is described in English, and then philosophers judge whether it is true that (...) S knows that p, or whether saying “S knows that p” is false, deviant, etc. in that situation. However, English is just one of over 6000 languages spoken around the world, and is the native language of less than 6% of the world’s population. When Western epistemology first emerged, in ancient Greece, English did not even exist. So why should we think that facts about the English word “know,” the concept it expresses, or subtle semantic properties of “S knows that p” have important implications for epistemology? Are the properties of the English word “know” and the English sentence ‘S knows that p’ shared by their translations in most or all languages? If that turned out to be true, it would be a remarkable fact that cries out for an explanation. But if it turned out to be false, what are the implications for epistemology? Should epistemologists study knowledge attributions in languages other than English with the same diligence they have shown for the study of English knowledge attributions? If not, why not? In what ways do the concepts expressed by ‘know’ and its counterparts in different languages differ? And what should epistemologists make of all this? (shrink)

This paper chronicles my introduction to and subsequent investigation of the Felix Experimental Group (FEG) and its exhibitions of classical physical mediumship. It’s been nearly a century since investigators have had the opportunity to carefully study standard spiritistic phenomena, including the extruding of ectoplasm, and the FEG is the only current physical mediumistic circle permitting any serious controls. The paper details a progressively stringent, personally supervised series of séances, culminating in some well-controlled experiments with video documentation in a secure and (...) private location belonging to one of the investigators. Regrettably, recent indications of fraud (explored also by Michael Nahm in this issue) have tarnished the case as a whole. However, it remains unclear how extensive the fraud has been. Accordingly, this paper evaluates the arguments both for and against the paranormality of the phenomena displayed under the author’s supervision. (shrink)

This paper examines the way Charles Darwin applied his domestic breeding analogy to the practical workings of species evolution: that application, it is argued, centered on Darwin's distinction between methodical and unconscious selection. Methodical selection, which entailed pairing particular individuals for mating purposes, represented conditions of strict geographic isolation, obviously useful for species multiplication (speciation). By contrast, unconscious selection represented an open landmass with a large breeding population. Yet Darwin held that this latter scenario, which often would include multiple ecological (...) subdistricts and thus partial isolation, was better suited for speciation than were isolated conditions. At the same time, many passages in Darwin's writings that apparently portrayed phyletic evolution exclusively (these including references to unconscious selection), actually applied to speciation as well, for phyletic change in a single district could constitute a local manifestation of a larger common-descent pattern. This generic use of "phyletic" change was reflected in Darwin's deployment of the unconscious selection analogy in his published writings as well as in his dispute with Moritz Wagner over the necessity of geographic isolation for speciation. We can thus understand Darwin's otherwise puzzling declaration in The Origin of Species that unconscious selection was 'more important' than the methodical approach. (shrink)

Food insecurity, and its extreme form, hunger, occur whenever the accessibility to an adequate supply of nutritional and safe foods becomes restricted or unpredictable. They are recurring problems in certain regions of the US, as well as in many parts of the world. According to nation-wide surveys conducted by the US Bureau of the Census, between 1996 and 1998 an estimated 9.7% of US households were classified as food insecure (6.2% being food insecure without evidence of hunger, and 3.5% being (...) food insecure with moderate to severe hunger). This means that approximately 10 million households each year did not always have access to enough food to meet basic needs. A potential tool in the fight against food insecurity and hunger is information technology (IT), since its use and range of application continue to grow at astonishing rates. The study presented here examined the question of how information technology, particularly the Internet, can be used to promote food security. The study used an action science research approach, and a case study strategy, with the food security system of Oktibbeha County, Mississippi selected as the case for study. The research design was a two-phase process. Phase one consisted of a needs assessment among food assistance organizations in Oktibbeha County, and included interviews of key food assistance personnel. Phase one also included a survey of IT subject matter experts to seek their opinions about the current state of Web-based information technology. Phase two involved an analysis of various IT implementation issues, as well as the development of a Web-based food security information system prototype tool. The needs assessment results indicated that (a) certain food security system and information needs existed among the food assistance organizations in Oktibbeha County, and (b) appropriate information technologies existed that could be applied to these needs. The food security needs related to better communication and coordination of information, such as program information, food site inventory information, client history information, food donation information, and nutrition education information. In regard to technology development, a variety of scenarios were examined. These included client-side approaches, server-side approaches, simple e-mail-based systems, Java-based systems, systems based on the Common Gateway Interface (CGI), and commercial database systems. In applying the needs assessment and survey results, the researcher developed a prototype Web site (including a series of online database tools) that could be used to promote food security in counties such as Oktibbeha County. The results of this research show that appropriate, Internet-based, IT holds promise for the reduction of certain social problems, such as food insecurity and hunger. (shrink)

Harry Collins is a science studies scholar no other description fits without qualification who has contributed enormously to the discussion of tacit knowledge. Collins says that he is providing an account for the ontologically bashful, meaning, presumably, that it does not carry the burdens of Durkheim's notion of the collective consciousness. Polanyi says that 'a wholly explicit knowledge is unthinkable'. Collins wants to translate this into 'strings must be interpreted before they are meaningful'. Somatic limits are the source of the (...) mystery element of tacit knowledge. In fact, machines can be programmed to do the things it involves, although they will do it in a different way. In Social Cartesianism, the individual is not the unit of analysis: the individual merely shares the collectivity's knowledge. Collins point in these contexts is that functional substitutability implies nothing about similarity in underlying causal structure. (shrink)

In this paper, we discuss the findings of two case studies of children’s semantic competence using sentences that contain the universal quantifier every. Children’s understanding of universal quantification, or lack of it, is probably the most controversial topic in current research on young children’s semantic competence. Even among researchers who draw upon linguistic theory in their investigations of child language, there seems to be a general consensus that preschool and even school-age children make ‘errors’ in interpreting sentences with the universal (...) quantifier, and that these ‘errors’ reveal non-adult grammatical knowledge of universal quantification. However, a handful of studies have recently demonstrated children’s knowledge of several aspects of universal quantification, and the present paper adds to that growing body of work. The studies we discuss assess preschool children’s awareness that the two arguments of the universal quantifier have different interpretative properties, because the restrictor of every (NP) is downward entailing, whereas its nuclear scope (VP) is upward entailing. The experimental findings of the present studies are difficult to reconcile on recent analyses that attribute non-adult grammatical knowledge to children. However, the findings fit well with the view that children’s grammars are essentially the same as those of adults, as the Continuity Assumption supposes. (shrink)

A central claim of Paul Horwich’s 1998 book Meaning was that meaning properties reduce to acceptance properties, where  a meaning property is a property of the form e means m for x, e being “a word or phrase—whether it be spoken, written, signed, or merely thought (i.e. an item of ‘mentalese’)” (44);  an acceptance property for an expression e relative to a person x is a relation of the form x is disposed to accept an e-containing sentence of (...) kind … in circumstances of kind ….

I argue that a new solution to the semantic paradoxes is possible based on truth-making. I show that with an appropriate understanding of what the ultimate truth and falsity makers of sentences are, it can be demonstrated that sentences like the liar are alethically undecidable. That means it cannot be said in principle whether such sentences are true, not true, false, not-false, neither true nor false, both true and false, and so on. I argue that this leads to a solution (...) to the semantic paradoxes that appears to be free of revenge problems, allows us to maintain classical logic and the validity of the T-schema. (shrink)

This chapter presents a brief history of American Rural Sociology. It discusses the key early figures, such as C.J. Galpin, Kenyon Butterfield, Dwight Sanderson, and Thomas Carver Nixon. But the focus is on the next generation, and the distinctive institutional character of rural sociology as it developed in the twenties and thirties, and evolved in relation to events in the postwar period. Rural sociology shared many features with the “Social Survey” movement, including its commitment to community development, and to some (...) extent its methods. The “Survey Movement” petered out, for reasons having to do with the willingness of communities to subject themselves to the kind of scrutiny needed for reform. The community studies of Rural Sociology were caught between similar forces, and were also politically vulnerable. Postwar rural sociology responded to these vulnerabilities, but faced changes in agriculture that undermined the original purpose of im - proving rural life. The field nevertheless retained its commitment to engagement, and found new ways of doing so. In this respect, it deviated significantly from general, which had an acrimonious split from the survey movement. Ironically, however, general sociology has returned to engagement, at a time that rural sociology has lost its original subject matter and raison d’être. (shrink)

Chesterton was a serious and even excellent philosopher, whose reputation has suffered because his style was so striking, and his conversion to Catholicism so unpopular with Whiggish Britons. He had many ?politically incorrect? opinions, but those ?faults? were symptoms of a greater virtue, his insistence that ?the whole object of history is to make us realize that humanity can be great and glorious, under conditions quite different and even contrary to our own?. His desire for a United Europe was not (...) for a larger, self?willed State, but for a continent of peasant proprietors, workers owning their own tools, citizens alive to their own local heritage. What he distrusted was the Laodicean mood that best defines modernity, that nothing is worth dying for but life is not worth living. What he consistently opposed was the power of businessmen and aristocrats, and their Whiggish supporters? habit of supposing that the actual course of history was inevitable. Speculation about might?have?beens (including the great might?have?been of medieval Christendom) is a way to subvert the oppressive weight of the present. His hope was for a revolution ('we may or may not see the New Jerusalem rebuilt. .. on our fields, but in the flesh we shall see Babylon fall'), one made easier by the realization that Babylon need never have been built.

Evaluating public health measures is one of the central tasks in public health ethics. Some public health measures incur the charge that they are paternalistic in an objectionable way. In a recent intriguing contribution to this journal, Thomas Nys responds to this complaint by setting out three challenges to be met if the charge is to be made good. The first challenge is that putatively objectionable public health measures in fact preserve autonomy; the second is that autonomy is not undermined (...) by measures that are the upshot of democratic processes; the third is that it is a mistake to charge measures intended to benefit others with being objectionably paternalistic. Nys's explicit aim in presenting these challenges is not to show that the charge of paternalism in public health is never sound, but to stimulate further discussion. My paper takes up this invitation by responding to each of the challenges Nys presents, including discussing where they fail and identifying which succeed. (shrink)

Davidson’s remark is fairly conventional stuff in contemporary philosophy, but the argument that informs it is elusive. Is this a kind of unformulated transcendental argument, which amounts to the claim that the ‘sharing’ of ‘language,’ in some unspecified sense of these terms, is a condition of the possibility of ‘communication’ in some unspecified sense of this term? Or is it a kind of inference to the best explanation in which there are no real alternativesan inference, so to speak, to the (...) only explanation? There are good reasons to be suspicious of arguments of this form. Yet this general picture, of some sort of shared stuff at the basis of language, is highly appealing, and so is its extension to practices generally. The claim that there is some class of things that could not happen, were it not for the existence of some sort of shared practices, is a commonplace, despite, and perhaps because of its vagueness.

Although less observable than the overt actions of fighting and assault, covert antisocial behaviors such as stealing and property destruction comprise an important subclass of externalizing behavior patterns, displaying considerable predictive power toward delinquency in adolescence. I discuss a laboratory paradigm for objective observation of such behaviors in children that has shown impressive concurrent and predictive validity among samples of boys with and without attention deficit hyperactivity disorder. Addressed herein are crucial questions regarding the ethics of tempting children to steal (...) objects and small amounts of money and to deface property as well as the types of informed consent and debriefing procedures utilized in research with this paradigm. Weighing ethical considerations alongside the ability to predict delinquent behavior presents provocative issues for those interested in understanding the development of antisocial behavior. (shrink)
