Extending techniques of Dowd and those of Poizat, we study computational complexity of in the case when is a generic oracle, where is a positive integer, and denotes the collection of all -query tautologies with respect to an oracle . We introduce the notion of ceiling-generic oracles, as a generalization of Dowd's notion of -generic oracles to arbitrary finitely testable arithmetical predicates. We study how existence of ceiling-generic oracles affects behavior of a generic (...) oracle, by which we show that is not a subset of is comeager in the Cantor space. Moreover, using ceiling-generic oracles, we present an alternative proof of the fact (Dowd) that the class of all -generic oracles has Lebesgue measure zero. (shrink)

"Divination and Human Nature" casts a new perspective on the rich tradition of ancient divination--the reading of divine signs in oracles, omens, and dreams. Popular attitudes during classical antiquity saw these readings as signs from the gods while modern scholars have treated such beliefs as primitive superstitions. In this book, Peter Struck reveals instead that such phenomena provoked an entirely different accounting from the ancient philosophers. These philosophers produced subtle studies into what was an odd but observable fact--that humans could (...) sometimes have uncanny insights--and their work signifies an early chapter in the cognitive history of intuition. Examining the writings of Plato, Aristotle, the Stoics, and the Neoplatonists, Struck demonstrates that they all observed how, setting aside the charlatans and swindlers, some people had premonitions defying the typical bounds of rationality. Given the wide differences among these ancient thinkers, Struck notes that they converged on seeing this surplus insight as an artifact of human nature, projections produced under specific conditions by our physiology. For the philosophers, such unexplained insights invited a speculative search for an alternative and more naturalistic system of cognition. Recovering a lost piece of an ancient tradition, "Divination and Human Nature" illustrates how philosophers of the classical era interpreted the phenomena of divination as a practice closer to intuition and instinct than magic.

Hrushovski originated the study of “flat” stable structures in constructing a new strongly minimal set and a stable 0-categorical pseudoplane. We exhibit a set of axioms which for collections of finite structure with dimension function δ give rise to stable generic models. In addition to the Hrushovski examples, this formalization includes Baldwin's almost strongly minimal non-Desarguesian projective plane and several others. We develop the new case where finite sets may have infinite closures with respect to the dimension function δ. (...) In particular, the generic structure need not be ω-saturated and so the argument for stability is significantly more complicated. We further show that these structures are “flat” and do not interpret a group. (shrink)

If we assume that “enhancement” names all efforts to boost human mental and physical capacities beyond the normal upper range found in our species, then enhancement covers such a broad range of interventions that it becomes implausible to think that there is any generic ethical case to be made either for or against it. Michael Sandel has recently made such a generic case, which focuses on the importance of respecting the “giftedness” of human nature. Sandel succeeds in diagnosing (...) an important worry we may have about the use of some enhancements by some parents, but his arguments are better understood as opposing “procrustean parenting” rather than enhancement in general.

We show that K-generic projective planes have Morley rank either two or infinity. We also show give a direct argument that such planes are not Desarguesian.

'The kind Lion' denotes a kind. Yet many generics are thought to denote kinds also, like the subject-terms in 'The lion has a mane', 'Dinosaurs are extinct', and 'The potato was cultivated in Ireland by the end of the 17th century.' This view may be adequate for the linguist's overall purposes--however, if we limit our attention to the theory of reference, it seems unworkable. The problem is that what is often predicated of kinds is not what is predicated of the (...) lion, dinosaurs, and the potato. Thus, kinds are sometimes said to be abstract objects, immanent universals, nominal essences, etc. But the lion is a predatory cat--it is not an abstract object, nor an immanent universal, nor a nominal essence. I consider several proposals about resolving the dilemma; however, the conclusion is that none of the proposals are adequate. We are thus hard pressed to make sense of allegedly kind-denoting generics, and the lesson is a "Socratic" one about the depths of our ignorance. (shrink)

A difficulty for alethic pluralism has been the idea that semantic evaluation of conjunctions whose conjuncts come from discourses with distinct truth properties requires a third notion of truth which applies to both of the original discourses. But this line of reasoning does not entail that there exists a single generic truth property that applies to all statements and all discourses, unless it is supplemented with additional, controversial, premises. So the problem of mixed conjunctions, while highlighting other aspects of (...) alethic pluralism worth investigating further, does not constitute an effective objection to it. (shrink)

Life-science art is a generic term which describes a new kind of collaboration between artists and scientists which adds a new dimension to the polemics of the ‘philosophy of art.’ Utilising the techniques and materials made available by developments in biotechnology, artists, and scientists produce objects not for scientific benefit but aesthetic objects designed to enchant, shock, or familiarize the audience with the fanciful applications to which this technology can be put: the creation of pig wings, fish that can (...) draw, rabbits that glow in the dark and dead men that appear to play chess.This paper investigates the moral implications of the incorporation of living and non-living plant, animal, and human tissue as part of the artistic palette. It is argued that the rupture between the beautiful and the good that characterises much of contemporary thinking directly leads to the morally dubious practices of life-science art and that there are very good reasons drawn from utilitarian and natural law traditions against such “artistic” endeavours.

What I have attempted to show in the foregoing is that: (1) For any frequency adjective f, there is an element of meaning common to both the adverbial and the generic usage of f; this is a function f′ from propositions to truth-values such that f′(Φ)′ is true at an interval i iff Φ′ is true at subintervals of i distributed through i in a certain way. (2) In an adverbial use of f, f′ functions like the corresponding frequency (...) adverb. (3) In a generic use of f, f′ quantifies the times intervals which a specified object is realized by some stage. (4) In their adverbial usage, frequency adjectives are not regular attributive adjectives at the level at which interpretation takes place, but are perhaps determiners. And (5) in their generic usage, frequency adjectives are adjectives at the level at which interpretation takes place.More generally, I hope to have suggested something of the range of uses to which frequency is put in natural language. That we effortlessly grasp what is meants by Monday, the Columbus Dispatch, autumn, the Today Show, and so on, demonstrates our fluency in interpreting certain sequences of objects, events, or states of affairs as sequences of values of some function cycling on a time-axis. Much more must ultimately be told about the psychological and anthropological significance of frequency. (shrink)

The Spartan Rhetra quoted by Plutarch in Lyc. vi. 2 consists of some thirty-seven words in an archaic Dorian or near-Dorian dialect: Plutarch says it was an oracle, and that later an extra clause was added by the kings Polydoros and Theopompos; he quotes this ‘added clause’ in vi. 8. I believe this Rhetra was not an oracle but an act of the Spartan Ekklesia; and I suspect that the ‘added clause’ was not added, but is an integral (...) part of the original act. But for our first objective this opinion matters less than Plutarch's opinion. Our first objective must be to recover Plutarch's text : and to do that, we must understand his interpretation.

Being a Christian involves metaphysical, epistemological, and social commitments that set Christians at variance with the dominant secular culture. Because Christianity is not syncretical, but proclaims the unique truth of its revelation, Christians will inevitably be placed in some degree of conflict with secular health care institutions. Because being Christian involves a life of holiness, not merely living justly or morally, Christians will also be in conflict with the ethos of many contemporary Christian health care institutions which have abandoned a (...) commitment to Christian spirituality. In this regard, managed care raises the special question of how Christian institutions can act morally under financial constraints and maintain their character while under the control of secular managers. This question itself raises the further question as to why health care institutions need even pose this query when there are Christian physicians and nurses who could work for less, or Christian men and women who could become sisters and brothers and work for nothing. Contemporary challenges to Christians to maintain their integrity in a post-Christian world have much of their force because Christians have failed to maintain traditional Christian spirituality. In the face of that failure, Christian physicians and nurses will find themselves in greater conflict with health care institutions, because few will any longer understand the requirements of traditional Christianity. In its place, they will have put a generic spirituality, a value-neutral understanding of the role of the health professional, and an anonymous commitment to social justice. (shrink)

Some philosophers suggest that the development of scientificknowledge is a kind of Darwinian process. The process of discovery,however, is one problematic element of this analogy. I compare HerbertSimon's attempt to simulate scientific discovery in a computer programto recent connectionist models that were not designed for that purpose,but which provide useful cases to help evaluate this aspect of theanalogy. In contrast to the classic A.I. approach Simon used, ``neuralnetworks'' contain no explicit protocols, but are generic learningsystems built on the model (...) of the interconnections of neurons in thebrain. I describe two cases that take the connectionist approach a stepfurther by using genetic algorithms, a form of evolutionary computationthat explicitly models Darwinian mechanisms. These cases show thatDarwinian mechanisms can make novel discoveries of complex, previouslyunknown patterns. With some caveats, they lend support to evolutionaryepistemology. (shrink)

Suffering evokes moral and metaphysical reflection, the bioethics of suffering concerns the proper ethos of living with suffering. Because empirical and philosophical explorations of suffering are imprisoned in the world of immanent experience, they cannot reach to a transcendent meaning. Even if religious and other narratives concerning the meaning of suffering have no transcendent import, they can have aesthetic and moral significance. This understanding of narratives of suffering and of their custodians has substantial ecumenical implications: chaplains can function as general (...) custodians of narratives and sustainers of a generic religious meaning. This understanding is contrary to traditional Christianity, which discloses a transcendent significance of human suffering found in a very particular history involving particular persons: Christ as the second Adam through the submission of the second Eve has taken on our nature so that we can be united with God. Human suffering is tied to human sin, not simply as a punishment for sin, much less as an opportunity to discharge a supposed temporal punishment due to sin. Human suffering is the result of our rebellious free choices. It provides an opportunity for humility and submission, so that, united to the cross of Christ, sin can be forgiven and suffering set aside in the Resurrection. Knowledge of this framing context for all human suffering is accessible not through rational argument. It is a knowledge garnered through repentance, purification of the heart, illumination by God's grace, and unification with God. Christian bioethics is embedded in the narrative of suffering, which is part of the history of salvation and which encompasses and places all of medicine in its terms. (shrink)

This note is a continuation of our former paper ''Complexity of the r-query tautologies in the presence of a generic oracle.'' We give a very short direct proof of the nonexistence of t-generic oracles, a result obtained first by Dowd. We also reconstitute a proof of Dowd's result that the class of all r-generic oracles in his sense has Lebesgue measure one.

Point-of-care evidence-based medicine websites allow physicians to answer clinical queries using recent evidence at the bedside. Despite significant research into the function, usability and effectiveness of these programmes, little attention has been paid to their ethical issues. As many of these sites summarise the literature and provide recommendations, we sought to assess the role of conflicts of interest in two widely used websites: UpToDate and Dynamed. We recorded all conflicts of interest for six articles detailing treatment for the following conditions: (...) erectile dysfunction, fibromyalgia, hypogonadism, psoriasis, rheumatoid arthritis and Crohn's disease. These diseases were chosen as their medical management is either controversial, or they are treated using biological drugs which are mostly available by brand name only. Thus, we hypothesised that the role of conflict of interest would be more significant in these conditions than in an illness treated with generic medications or by strict guidelines. All articles from the UpToDate articles demonstrated a conflict of interest. At times, the editor and author would have a financial relationship with a company whose drug was mentioned within the article. This is in contrast with articles on the Dynamed website, in which no author or editor had a documented conflict. We offer recommendations regarding the role of conflict of interest disclosure in these point-of-care evidence-based medicine websites. (shrink)

Plutarch concludes his chapter on the Rhetra with six lines of Tyrtaios: φοβου κοςσαντες Πυθωνθεν οκαδ' νεικαν1 μαντεας τε θεο κα τελεντ' πεα ρχειν μν βουλῦς θεοτιμτους βασιλας οσι μλει Σπρτας μερεσσα πλις πρεσβτας τε γροντας, πειτα δ δημτας νδρας πθεαις τραις ντααπαμειβομνους.

The burden has to be borne by the one word εθεαις: ‘the Kings and gerontes shall initiate business, the demos shall reply with undistorted rhetrai’ or ‘shall respond to the rhetrai without distorting them’ . If εθεαις is given enough weight, the oracle which Tyrtaios quotes may be held to forbid the ‘excessive amendment’ against which Clause III was aimed. (shrink)

Since the 1970s, the United States has adopted a trade policy agenda that has forced countries to trade away flexible patent provisions for access to US markets. While pharmaceutical companies have argued that the recognition of patent rights is essential for recovering investments in research and development of pharmaceuticals and incentivizing future innovation, the lack of competition has had damaging consequences for public health, as companies tend to set the prices of treatments beyond the reach of consumers and government programs. (...) Thailand and Brazil are bound by law to provide universal access to anti-retroviral treatment (ART) to People Living with HIV/AIDS (PLWHA). This has been made possible in part due to the universal health care systems in each country and the countries' local technical and industrial capacities that provide the government with affordable generic medicines. The introduction of stronger intellectual property protection laws however, has limited possibilities for procuring generic medicines and inflated the cost of treatment. Between 2006–2008, Thailand and Brazil used compulsory licensing to authorize generic competition against the consent of the pharmaceutical companies in order to guarantee the right to health and ensure the viability of government health budgets. This paper will demonstrate how the interaction between individual / collective action and structural and institutional elements in Thailand and Brazil produced propitious conditions for each country to assert the primacy of health over patent rights.

Let ${\mathbb{B}}$ and ${\mathbb{C}}$ be Boolean algebras and ${e: \mathbb{B}\rightarrow \mathbb{C}}$ an embedding. We examine the hierarchy of ideals on ${\mathbb{C}}$ for which ${ \bar{e}: \mathbb{B}\rightarrow \mathbb{C} / \fancyscript{I}}$ is a regular (i.e. complete) embedding. As an application we deal with the interrelationship between ${\fancyscript{P}(\omega)/{{\rm fin}}}$ in the ground model and in its extension. If M is an extension of V containing a new subset of ω, then in M there is an almost disjoint refinement of the family ([ω]ω) V (...) . Moreover, there is, in M, exactly one ideal ${\fancyscript{I}}$ on ω such that ${(\fancyscript{P}(\omega)/{{\rm fin}})^V}$ is a dense subalgebra of ${(\fancyscript{P}(\omega)/\fancyscript{I})^M}$ if and only if M does not contain an independent (splitting) real. We show that for a generic extension V[G], the canonical embedding $$\fancyscript{P}^V(\omega){/}{\rm fin}\hookrightarrow \fancyscript{P}(\omega){/}(U(Os)(\mathbb{B}))^G$$ is a regular one, where ${U(Os)(\mathbb{B})}$ is the Urysohn closure of the zero-convergence structure on ${\mathbb{B}}$.

Let I be a countable jump ideal in $\mathscr{D} = \langle \text{The Turing degrees}, \leq\rangle$ . The central theorem of this paper is: a is a uniform upper bound on I iff a computes the join of an I-exact pair whose double jump a (1) computes. We may replace "the join of an I-exact pair" in the above theorem by "a weak uniform upper bound on I". We also answer two minimality questions: the class of uniform upper bounds on I (...) never has a minimal member; if ∪ I = L α [ A] ∩ ω ω for α admissible or a limit of admissibles, the same holds for nice uniform upper bounds. The central technique used in proving these theorems consists in this: by trial and error construct a generic sequence approximating the desired object; simultaneously settle definitely on finite pieces of that object; make sure that the guessing settles down to the object determined by the limit of these finite pieces.

This explores what responsible business practice within the context of Malaysia, an Eastern collective society, diverging from the Western individualistic society where most Corporate Social Responsibility (CSR) research originates. A bottom-up approach was adopted, incorporating different stakeholder perspectives of a case-study firm, widely acknowledged for its CSR programs. Concept mapping method was selected because it is a structural conceptualization method designed to organize and represent ideas from an identified group adding structure to disorganized and subjective ideas. By using concept mapping (...) all the various perspectives and ideas were brought together to create a single conceptualization. The findings from the concept mapping present 101 statements which produced seven clusters; Products & Services, Community Oriented, Stakeholder & Business Value, Employee Oriented, Legal & Ethical Responsibilities, Environmental & Social Oriented, and Philanthropic Oriented. These clusters covered the whole conceptual domain of Corporate Citizenship and demonstrated multiple CSR theories, including corporate sustainability, stakeholder concept, and shared value, were apparent, while also uncovering some unique aspects from the normative stakeholder perspective. The implications of this study suggest that while some aspects of globally institutionalized CSR are generically accepted, there are contextually specific aspects which need to be considered as these may contradict or conflict with the “global” standards.

Context: The use of first-person micro-phenomenological interviews and their productive interaction with third-person physiological data is a challenging and pressing issue in order to offer an effective and fruitful application of Varela’s neurophenomenological hypothesis. Problem: We aim at offering a generative method of analysis of first-person micro-phenomenological interviews using third-person physiological data. Our challenge is to describe this generative first-person analysis with the third-person physiological framework rather than put Varela’s hypothesis into practice in a generative way (as we did in (...) another paper. Method: The present contribution is a first pioneering study as far as the exposition of such an interactive generative methodology is concerned. It is also a new issue insofar as it deals with a case study, surprise in depression, that has not been thoroughly dealt with so far, either in philosophy or in psychopathology. Results: We show that the analysis of first-person data is an intrinsic generative one, insofar as new refined categories and multifarious circular micro- and macro-processes were discovered in the very process of analyzing. They provide the initial structural generic third-person description of surprise inherited both from philosophical phenomenological a priori categories and from the experimental startle setting with a refined micro-segmentation of the dynamic of the experience. Implications: Our article could be of interest to neurophenomenologists looking for an effective application and to researchers in quest of a method of analysis of first-person data. The present limitations are due to the still preliminary data-results we need to complete. Constructivist content: The article is directly linked to Varela’s neurophenomenological program and aims at extending and reforming it with a cardio-phenomenological approach. Keywords: First-person micro-phenomenological interviews, surprise, generative analysis of first-person data, depression, cardio-phenomenology, generative categories. (shrink)

A popular goal in psychological science is to understand human cognition and behavior in the ‘real world’. In contrast, researchers have typically conducted their research in experimental research settings, a.k.a. the ‘psychologist’s laboratory’. Critics have often questioned whether psychology’s laboratory experiments permit generalizable results. This is known as the ‘real-world or the lab’-dilemma. To bridge the gap between lab and life, the concept of ecological validity has been widely used to evaluate whether laboratory experiments resemble and generalize to the ‘real (...) world’. However, researchers seldom define what they mean with this concept, nor are there any guidelines or criteria available for evaluating a study’s ecological validity. In our view, the popular concept of ecological validity is ill-formed, lacks specificity, and falls short of adequately addressing the fundamental problem of generalizability. In order to move beyond this ‘real-world or the lab’-dilemma, we believe that researchers should be more specific about the contexts of behaviors they are interested in, instead of aiming to understand human cognition and behavior in the ‘real world’. We argue that this is a more constructive way of uncovering the context-specific and context-generic principles of human cognition and behavior. (shrink)

The new field of experimental philosophy has emerged as the methods of psychological science have been brought to bear on traditional philosophical issues. Oxford Studies in Experimental Philosophy will be the place to go to see outstanding new work in the field. It will feature papers by philosophers, papers by psychologists, and papers co-authored by people in both disciplines. The series heralds the emergence of a truly interdisciplinary field in which people from different disciplines are working together to address a (...) shared set of questions. The inaugural volume is roughly structured into four sections. The first three papers focus on recent developments in moral psychology, a topic that has seen lively debate and a great deal of progress over the last decade. The second section highlights three contributions that bring new methods to moral psychology: formal modeling and special populations. The third section brings together four papers that adopt an experimental philosophy approach to novel topics, including intuitive dualism, generics, joint action, and happiness. And the last two papers provide critical and historical context to the development of experimental philosophy. (shrink)

Objectives To conduct an independent evaluation of the first phase of the Health Foundation’s Safer Patients Initiative (SPI), and to identify the net additional effect of SPI and any differences in changes in participating and non-participating NHS hospitals. Design Mixed method evaluation involving five substudies, before and after design. Setting NHS hospitals in the United Kingdom. Participants Four hospitals (one in each country in the UK) participating in the first phase of the SPI (SPI1); 18 control hospitals. Intervention The SPI1 (...) was a compound (multi-component) organisational intervention delivered over 18 months that focused on improving the reliability of specific frontline care processes in designated clinical specialties and promoting organisational and cultural change. Results Senior staff members were knowledgeable and enthusiastic about SPI1. There was a small (0.08 points on a 5 point scale) but significant (P<0.01) effect in favour of the SPI1 hospitals in one of 11 dimensions of the staff questionnaire (organisational climate). Qualitative evidence showed only modest penetration of SPI1 at medical ward level. Although SPI1 was designed to engage staff from the bottom up, it did not usually feel like this to those working on the wards, and questions about legitimacy of some aspects of SPI1 were raised. Of the five components to identify patients at risk of deterioration—monitoring of vital signs (14 items); routine tests (three items); evidence based standards specific to certain diseases (three items); prescribing errors (multiple items from the British National Formulary); and medical history taking (11 items)—there was little net difference between control and SPI1 hospitals, except in relation to quality of monitoring of acute medical patients, which improved on average over time across all hospitals. Recording of respiratory rate increased to a greater degree in SPI1 than in control hospitals; in the second six hours after admission recording increased from 40% (93) to 69% (165) in control hospitals and from 37% (141) to 78% (296) in SPI1 hospitals (odds ratio for “difference in difference” 2.1, 99% confidence interval 1.0 to 4.3; P=0.008). Use of a formal scoring system for patients with pneumonia also increased over time (from 2% (102) to 23% (111) in control hospitals and from 2% (170) to 9% (189) in SPI1 hospitals), which favoured controls and was not significant (0.3, 0.02 to 3.4; P=0.173). There were no improvements in the proportion of prescription errors and no effects that could be attributed to SPI1 in non-targeted generic areas (such as enhanced safety culture). On some measures, the lack of effect could be because compliance was already high at baseline (such as use of steroids in over 85% of cases where indicated), but even when there was more room for improvement (such as in quality of medical history taking), there was no significant additional net effect of SPI1. There were no changes over time or between control and SPI1 hospitals in errors or rates of adverse events in patients in medical wards. Mortality increased from 11% (27) to 16% (39) among controls and decreased from 17% (63) to 13% (49) among SPI1 hospitals, but the risk adjusted difference was not significant (0.5, 0.2 to 1.4; P=0.085). Poor care was a contributing factor in four of the 178 deaths identified by review of case notes. The survey of patients showed no significant differences apart from an increase in perception of cleanliness in favour of SPI1 hospitals. Conclusions The introduction of SPI1 was associated with improvements in one of the types of clinical process studied (monitoring of vital signs) and one measure of staff perceptions of organisational climate. There was no additional effect of SPI1 on other targeted issues nor on other measures of generic organisational strengthening. (shrink)

Since Darwin's theory of evolution by natural selection, the idea of descent with modification came to dominate systematics, and so the study of morphology became subgugated to the reconstruction of phylogenies. Reinstating the organism in the theory of evolution (Ho & Saunders, 1979; Webster & Goodwin, 1982) leads to a project inrational taxonomy (Ho, 1986, 1988a), which attempts to classify biological forms on the basis of transformations on a given dynamical structure.Does rational taxonomy correspond to thenatural system that Linnaeus and (...) his contemporaries as well as all pre-Darwinian morphologists had in mind? Here, we examine how rational taxonomy and the natural system can coincide in the dynamics of processes generating forms during development, which conferexclusivity, genericity androbustness to the forms that do exist. We use the example of segmentation, especially inDrosophila, as an illustration to explore the implications of rational taxonomy for evolution and systematics, and the relationship between ontogeny and phylogeny.

Generic chaplaincy is the result of a devaluing of religious worship and belief to the merely instrumental and experiential. It is an expectable consequence of non-belief in the unique object that would render religious worship intrinsically meaningful and valuable. Generic chaplaincy has no place because all desire God, yet not all have found Him in the fullness with which He has revealed Himself to us, or even in the fullness with which we may be aware of Him through (...) natural reason. In consequence, not all are equally aware of God. A chaplaincy that challenges patients respectfully, and encourages spiritual growth and awareness, including the overcoming of sin and error, is appropriate. (shrink)

In the early nineties of the previous century, leaf languages were introduced as a means for the uniform characterization of many complexity classes, mainly in the range between P and PSPACE . It was shown that the separability of two complexity classes can be reduced to a combinatorial property of the corresponding defining leaf languages. In the present paper, it is shown that every separation obtained in this way holds for every generic oracle in the sense of Blum (...) and Impagliazzo. We obtain several consequences of this result, regarding, e. g., universal oracles, simultaneous separations and type-2 complexity. (shrink)

Consensus has it that generic sentences such as “Dogs bark” and “Birds fly” contain, at the level of logical form, an unpronounced generic operator: Gen. On this view, generics have a tripartite structure similar to overtly quantified sentences such as “Most dogs bark” and “Typically, birds fly”. I argue that Gen doesn’t exist and that generics have a simple bipartite structure on par with ordinary atomic sentences such as “Homer is drinking”. On my view, the subject terms of (...) generics are kind-referring. The interesting truth conditions characteristic of generics arise from the interesting ways in which kinds inherit properties from their members. (shrink)

Generics are sentences such as Birds fly, which express generalizations. They are prevalent in speech, and as far as is known, no human language lacks generics. Yet, it is very far from clear what they mean. After all, not all birds fly—penguins don’t! -/- There are two general views about the meaning of generics in the literature, and each view encompasses many specific theories. According to the inductivist view, a generic states that a sufficient number of individuals satisfy a (...) certain property—in the example above, it says that sufficiently many birds fly. This view faces the complicated problem of spelling out exactly how many is “sufficiently many” in a way that correctly captures the intuitive truth conditions of generics. -/- An alternative, the rules and regulations view, despairs from this project and proposes instead that generics directly express rules in the world. Rules are taken to be abstract objects, which are not related to the properties of specific individuals. This view faces the difficult problem of explaining how people come to know of such rules when judging the truth of falsity of generics, and accounting for the strong intuition that a sentence such as Birds fly talks about birds, not abstract objects. -/- What seems to be beyond dispute is that generics, even if they do not express rules, are lawlike: they state non-accidental generalizations. Many scholars have taken this fact to indicate that generics are parametric on possible worlds: they refer to worlds other than the actual world. This, again, raises the problem of how people come to know about what happens in these other worlds. However, a rigorous application of standard tests for intensionality shows that generics are not, in fact, parametric on possible worlds, but only on time. This unusual property may explain much of the mystery surrounding generics. -/- Another mysterious property of generics is that although there is no language without them, there is no linguistic construction that is devoted to the expression of genericity. Rather, generics can be expressed in a variety of ways, each of which can also express nongenerics. Yet, each manifestation of generics differs subtly (or sometimes not so subtly) in its meaning from the others. -/- Even when these and other puzzles of genericity are solved, one mystery would remain: Why are generics, which are so easy to produce and understand in conversation, so difficult to analyze?

The relativized propositional calculus is a system of Boolean formulas with query symbols. A formula in this system is called a one-query formula if the number of occurrences of query symbols is just one. If a one-query formula is a tautology with respect to a given oracle A then it is called a one-query tautology with respect to A. By extending works of Ambos-Spies (1986) and us (2002), we investigate the measure of the class of all oracles A such (...) that the set of all one-query tautologies with respect to A does not p-btt-reduce to A, where p-btt denotes polynomial-time bounded-truth-table. We show that certain Dowd-type generic oracles all belong to the class, and hence measure of the class is one. (shrink)

Ducks lay eggs' is a true sentence, and `ducks are female' is a false one. Similarly, `mosquitoes carry the West Nile virus' is obviously true, whereas `mosquitoes don't carry the West Nile virus' is patently false. This is so despite the egg-laying ducks' being a subset of the female ones and despite the number of mosquitoes that don't carry the virus being ninety-nine times the number that do. Puzzling facts such as these have made generic sentences defy adequate semantic (...) treatment. However complex the truth conditions of generics appear to be, though, young children grasp generics more quickly and readily than seemingly simpler quantifiers such as `all' and `some'. I present an account of generics that not only illuminates the strange truth conditions of generics, but also explains how young children find them so comparatively easy to acquire. I then argue that generics give voice to our most cognitively primitive generalizations and that this hypothesis accounts for a variety of facts ranging from acquisition patterns to cross-linguistic data concerning the phonological articulation of operators. I go on to develop an account of the nature of these cognitively fundamental generalizations and argue that this account explains the strange truth-conditional behavior of generics. (shrink)

Generic claims like ‘women stay home and raise children’ and ‘boys don’t cry’ are normative generics: generic claims that express a norm. The truth conditions of normative generics are even harder to account for than those for more descriptive generics like ‘ducks lay eggs.’ Until recently, such generics were treated as deviant and thus not accounted for in standard accounts of generics. But recent work on the semantics and pragmatics of normative generics has changed that. In light of (...) this recent work, I propose that a speech act analysis of normative generics as instructions will shed light on normative generics. I end by discussing the ways in which this might allow us to use generics to counter harmful speech. (shrink)

Generic statements are commonly expressed using the bare plural – ‘tigers are striped’ – or the indefinite singular – ‘a tiger is striped’. Notoriously, some generics can be expressed using the bare plural locution, but not the indefinite singular; bare plural generics and indefinite singular generics pattern differently. I explore this phenomenon as it applies to normative generic statements: expressions like boys don’t cry, women are kind and nurturing, children are seen and not heard – that convey something (...) over and above (and even distinct from) the descriptive reading. I argue that we should look to a metalinguistic theory of generics to understand indefinite singular normative generics. That is, a normative indefinite singular generic is a proposal about what to include in the extension of the generic term. This theory explains why it is more often than not that felicitous indefinite singular generics are about social kind terms. I argue that this explains a crucial way in which language shapes the social world. When we say things like (2), we propose definitions and uses for the word ‘boy’. Such proposals and their consequences actually impact the behavior of the groups they pick out, as well as the attitudes of others towards those groups. (shrink)

A generic computation of a subsetAof ℕ is a computation which correctly computes most of the bits ofA, but which potentially does not halt on all inputs. The motivation for this concept is derived from complexity theory, where it has been noticed that frequently, it is more important to know how difficult a type of problem is in the general case than how difficult it is in the worst case. When we study this concept from a recursion theoretic point (...) of view, to create a transitive relationship, we are forced to consider oracles that sometimes fail to give answers when asked questions. Unfortunately, this makes working in the generic degrees quite difficult. Indeed, we show that generic reduction is$\Pi _1^1$―complete. To help avoid this difficulty, we work with the generic degrees of density-1 reals. We demonstrate how an understanding of these degrees leads to a greater understanding of the overall structure of the generic degrees, and we also use these density-1 sets to provide a new a characterization of the hyperartithmetical Turing degrees.

Earlier, we have studied computations possible by physical systems and by algorithms combined with physical systems. In particular, we have analysed the idea of using an experiment as an oracle to an abstract computational device, such as the Turing machine. The theory of composite machines of this kind can be used to understand (a) a Turing machine receiving extra computational power from a physical process, or (b) an experimenter modelled as a Turing machine performing a test of a known (...) physical theory T.Our earlier work was based upon experiments in Newtonian mechanics. Here we extend the scope of the theory of experimental oracles beyond Newtonian mechanics to electrical theory. First, we specify an experiment that measures resistance using a Wheatstone bridge and start to classify the computational power of this experimental oracle using non-uniform complexity classes. Secondly, we show that modelling an experimenter and experimental procedure algorithmically imposes a limit on our ability to measure resistance by the Wheatstone bridge.The connection between the algorithm and physical test is mediated by a protocol controlling each query, especially the physical time taken by the experimenter. In our studies we find that physical experiments have an exponential time protocol; this we formulate as a general conjecture. Our theory proposes that measurability in Physics is subject to laws which are co-lateral effects of the limits of computability and computational complexity. (shrink)
