AI and people do not compete on a level-playing field. Self-driving vehicles may be safer than human drivers, but laws often penalize such technology. People may provide superior customer service, but businesses are automating to reduce their taxes. AI may innovate more effectively, but an antiquated legal framework constrains inventive AI. In The Reasonable Robot, Ryan Abbott argues that the law should not discriminate between AI and human behavior and proposes a new legal principle that will ultimately improve human (...) well-being. This work should be read by anyone interested in the rapidly evolving relationship between AI and the law. (shrink)

This book presents the most important problems of reference and considers their solution. It presupposes no technical knowledge, presents analyses from first principles, illustrates every stage with examples, and is written with verve and clarity. This is the ideal introduction to reference for students of linguistics and philosophy of language.

Abbott replies to each of Hauser's arguments. Problem solving by chimpanzees and evidence of recursion in the thought of a feral human being suggest that natural language is not necessary for productive thought. Communication would be trivial if the inner language were the outer language, but it is not. The decryption analogy Hauser uses is flawed, and it is not clear which way Occam's razor cuts.

This paper argues that the dominance of linear models has led many sociologists to construe the social world in terms of a "general linear reality." This reality assumes (1) that the social world consists of fixed entities with variable attributes, (2) that cause cannot flow from "small" to "large" attributes/events, (3) that causal attributes have only one causal pattern at once, (4) that the sequence of events does not influence their outcome, (5) that the "careers" of entities are largely independent, (...) and (6) that causal attributes are generally independent of each other. The paper discusses examples of these assumptions in empirical work, consider standard and new methods addressing them, and briefly explores alternative models for reality that employ demographic, sequential, and network perspectives.

This would have been a better book if Sampson had argued his main point, the usefulness of the Simonian principle as an explanation of the evolution, structure, and acquisition of language, on its own merits, instead of making it subsidiary to his attack on ‘limited-minders’ (e.g., Noam Chomsky). The energy he has spent on the attack he might then have been willing and able to employ in developing his argument at reasonable length and detail. He might then have found that (...) argument faulty, or even wrong. Underdeveloped as it is, however, his point about the Simonian principle does seem to have thepossibility of some significance in understanding the empirical issues of this book (and the dichotomy of ‘limited’ and ‘creative’ minds is certainly not one of these).What Sampson has done inMaking Sense has the appearance of science, and theoretical linguistics, and therefore it is somewhat puzzling to find the conclusions that the human mind cannot be scientifically studied (p. 10), and that theoretical linguistics is a “mirage” (p. 210). His statement that It may still seem worthwhile to some to work out the exact implications for present-day linguistic structure of the fact that languages are evolved systems, but I cannot see that there is much glamour or, indeed, much substance in this task (p. 210) would surely be surprising to a geneticist or ethologist. We hope his apparent misunderstanding on this point will not lead him to give up his profession, in which he seems willing and able to make a significant contribution.What in particular is required is a clear indication of how the Simonian principle imposes itself in the ontogenesis of language. Consider Chomsky's example of the rule for forming questions in English. For sentence (1) below, children able to deal with such examples would give (2) but not (3) as the corresponding question (Chomsky, 1975, p. 31).The man who is tall is in the room.Is the man who is tall in the room?*Is the man who tall is in the room?Now compare Sampson's evolutionary explanation for the structure-dependence of rules which is illustrated in (1)-(3): “once a behavior-pattern has become thoroughly established, it will tend to be treated as a fixed given when used as a constituent of a more complex, later-learned behavior-pattern” (p. 183). In order for this to account for Chomsky's example it would have to be the case that children learn relative clauses before they learn questions, which simply isn't true.In conclusion, we wish not to seem unaware of the problems with the position Sampson is attacking, or unaware of the sometimes dogmatic way it too has been presented. Chomsky's hypothesis of innate linguistic ideas seems, fundamentally, to derive from the claimed rapidity and uniformity of language acquisition in the face of limited and degenerate data. Chomsky appears to have been unwilling to argue these points directly or to show their relation to others, for which he has argued, for example, the implausibility of some abstract constraint's having been learned (cf. 1971, pp. 22–44; 1975, pp. 30–33; 1980, pp. 35–52). And almost from his first invoking of rationalism in support of his linguistic method, Chomsky has himself resorted to an unnecessarily polemical attack on empiricism (cf. 1965, p. 58, n. 33). The innateness issue is just not clear or simple enough to justify so much animus, or even conviction. (shrink)

Providing a theory of moral practice for a contemporary sociological audience, Owen Abbott shows that morality is a relational practice achieved by people in their everyday lives. He moves beyond old dualisms—society versus the individual, social structure versus agency, body versus mind—to offer a sociologically rigorous and coherent theory of the relational constitution of the self and moral practice, which is both shared and yet enacted from an individualized perspective. In so doing, The Self, Relational Sociology, and Morality in (...) Practice not only offers an urgently needed account of moral practice and its integral role in the emergence of the self, but also examines morality itself within and through social relations and practices. Abbott’s conclusions will be of interest to social scientists and philosophers of morality, those working with pragmatic and interactionist approaches, and those involved with relational sociology and social theory.

The prototypes of definiteness and indefiniteness in English are the definite article the and the indefinite article a/an, and singular noun phrases (NPs)1 determined by them. That being the case it is not to be predicted that the concepts, whatever their content, will extend satisfactorily to other determiners or NP types. However it has become standard to extend these notions. Of the two categories definites have received rather more attention, and more than one researcher has characterized the category of definite (...) NPs by enumerating NP types. Westerståhl (1985), who is concerned only with determiners in the paper cited, gives a very short list: demonstrative NPs, possessive NPs, and definite descriptions. Prince (1992) lists proper names and personal pronouns, as well as NPs with the, a demonstrative, or a possessive NP as determiner. She notes, in addition, that “certain quantifiers (e.g. all, every) have been argued to be definite” (Prince 1992: 299). This list, with the quantifiers added, agrees with that given by Birner & Ward (1998, 114). Ariel (1988, 1990) adds null anaphoric NPs. (shrink)

Some presuppositions seem to be weaker than others in the sense that they can be more easily neutralized in some contexts. For example some factive verbs, most notably epistemic factives like know, be aware, and discover, are known to shed their factivity fairly easily in contexts such as are found in (1). (1) a. …if anyone discovers that the method is also wombat-proof, I’d really like to know! b. Mrs. London is not aware that there have ever been signs erected (...) to stop use of the route… c. Perhaps God knows that we will never reach the stars…. (The examples in (1) are all naturally occurring ones, discovered by David Beaver with the aid of Google; cf. Beaver 2002, exx. 32, 43, and 51, respectively.) On the other hand some other factives, e.g. regret, matter, and be surprised, do not exhibit the same type of behavior: (2) a. If any of the students regrets behaving badly, they’ll let us know. b. It doesn’t matter that the chimpanzees escaped. c. Was Bill surprised that spinach was included? Unlike the examples in (1), those in (2) could not be used appropriately in contexts where the speaker was not assuming that the complement clause was true. Our main concern will be trying to find the cause of this difference. However, before we get to that, we will look more closely at the concept “presupposition” itself, as well as its close neighbor in the linguistic literature, “conventional implicature” (section 2), and also at various ways of getting rid of presuppositions (section 3). In section 4 we will investigate two possible explanations for differences in presupposition triggering – the “lexical alternative” approach of Abusch (2002, 2005), and a suggestion of Ladusaw’s involving detachability of presuppositions. The final section contains concluding remarks. (shrink)

This paper presents problems for Stalnaker’s common ground theory of presupposition. Stalnaker (Linguist and Philos 25:701–721, 2002) proposes a 2-stage process of utterance interpretation: presupposed content is added to the common ground prior to acceptance/rejection of the utterance as a whole. But this revision makes presupposition difficult to distinguish from assertion. A more fundamental problem is that the common ground theory rests on a faulty theory of assertion—that the essence of assertion is to present the content of an utterance as (...) new information. Many examples are presented of utterances which are felicitous but not informative in this way. (shrink)

In this article I generalize ecological theory by developing the notion of separate but linked ecologies. I characterize an ecology by its set of actors, its set of locations, and the relation it involves between these. I then develop two central concepts for the linkage of ecologies: hinges and avatars. The first are issues or strategies that "work" in both ecologies at once. The second are attempts to institutionalize in one ecology a copy or colony of an actor in another. (...) The article investigates the first of these concepts using two detailed examples of hinge analysis between the professional and political ecologies. Both concern medical licensing, the first in 19th-century New York and the second in 19th-century England. For the avatar concept, the article analyzes four less detailed cases linking the professional and university ecologies: computer science, criminal justice, clinical psychology, and applied economics.

The phrase "natural kind term" has come into the linguistic and philosophical literature in connection with well-known work of Kripke (1972) and Putnam (1970, 1975a). I use that phrase here in the sense it has acquired from those and subseqnent works on related topics. This is not the transparent sense of the phrase. That is, if I am right in what follows there are words for kinds of things existing in nature which are not natural kind terms in the current (...) sense - e.g. planet, woman, and weed. I use the term "nondescriptional", following Salmon (1981), to mean "lacking a Fregean sense", where a Fregean sense is taken to be a property or group of properties semantically associated with an expression which determines its denotation. I hope that the term "nondescriptional" will be clarified in subsequent discussion, but perhaps a few words about it and its opposite, "descriptional", would be useful here. These terms (as Salmon notes (p.15, n. 11)) should be taken as technical terms. The idea is that descriptional words, of which bachelor is the overwhelmingly favorite example, express a semantic content, or sense, which is what mediates their denotation. Entities fall in their denotation in virtue of possessing the property or properties expressed as their sense. (It is not necessary, however, that this sense be as easily paraphrasable with descriptive synonyms as it is typically held to be in the case of bachelor, or even that it be paraphrasable at all.) In the case of nondescriptional words there is no Fregean sense to mediate the link between word and object. Hence such terms are described by what Salmon, following Kaplan, calls "the theory of direct reference". What it is that does associate such terms with their denotations is another question which will be touched on briefly at the end. I have several aims in this paper. The first is to defend a conservative position on nondescriptionality. I will argue that relatively few natural language words have this property. My other aims are primarily clarificatory. Among the issues I would like to clarify are those connected with the determination of this property and flae explanation of why it exists, its relationship with other properties such as rigid designation and essentiality, and its significance for lexical semantics. The organization of the paper is as follows. The first section identifies the position taken here on the question of which expressions are nondescriptional and provides a general defense of it. The second section is a critical examination of criteria associated with nondescriptionality. In the third section provide further defense for the conservative position, and in the fourth section we turn to related issues in lexical semantics. (shrink)

In this article I develop Heidegger's phenomenology of poetry, showing that it may provide grounds for rejecting claims that he lapses into linguistic idealism. Proceeding via an analysis of the three concepts of language operative in the philosopher's work, I demonstrate how poetic language challenges language's designative and world-disclosive functions. The experience with poetic language, which disrupts Dasein's absorption by emerging out of equipmentality in the mode of the broken tool, brings Dasein to wonder at the world's existence in such (...) a way that doubt about its reality cannot enter the picture.

New brain-computer interface and neuroimaging techniques are making differentiation less ambiguous and more accurate between unresponsive wakefulness syndrome patients and patients with higher cognitive function and awareness. As research into these areas continues to progress, new ethical issues will face physicians of patients suffering from total locked-in syndrome, characterized by complete loss of voluntary muscle control, with retention of cognitive function and awareness detectable only with neuroimaging and brain-computer interfaces. Physicians, researchers, ethicists and hospital ethics committees should be aware of (...) and prepared to handle ethical issues unique to these totally locked-in patients. Several thought experiments are discussed, to highlight potential ethical dilemmas surrounding surrogate decision-making, autonomy, end-of-life care, and pediatric care, which will be unique to total LIS patients. These, along with other ethical problems especially relevant to total LIS patients, merit further discussion among physicians, researchers, ethicists and hospital ethics committees, to facilitate consensus regarding these issues, and improve patient care.

We will look at several theories of indicative conditionals grouped into three categories: those that base its semantics on its logical counterpart (the material conditional); intensional analyses, which bring in alternative possible worlds; and a third subgroup which denies that indicative conditionals express propositions at all. We will also look at some problems for each kind of approach.

Lyman Abbott was an American liberal theologian and a confidant of Theodore Roosevelt. He was a moderate man who sought to re-establish Christian faith among the American people in a period of change. This book, first published in 1893, argued that spiritual experience is always new and therefore every age requires a new expression for it. A believer in the possibility of harmonious coexistence between the Church and evolutionary theory, Abbott proposed a 'more intelligible and credible' religion that (...) endeavoured to sustain faith by expressing it in contemporary terms. He maintained that science and faith were compatible and that both natural and spiritual elements belonged to a shared kingdom governed by the law of progress. Blending faith in historical Christianity with belief in progress and evolutionary theory, Abbott aimed to provide a bridge between religious life and late nineteenth-century philosophical thought.

Partee (1973) discussed quotation from the perspective of the then relatively new theory of transformational grammar.2 As she pointed out, the phenomenon presents many curious puzzles. In some ways quotes seem quite separate from their surrounding text; they may be in a different dialect, as in her example in (1), (1) ‘I talk better English than the both of youse!’ shouted Charles, thereby convincing me that he didn’t. [Partee (1973):ex. 20] or even in a different language, as in (2): (2) (...) Louise said ‘Je voudrais un auto-da-f´e’, but I didn’t know what she meant. (shrink)

This grounded study investigated the negotiation of authorship by faculty members, graduate student mentors, and their undergraduate protégés in undergraduate research experiences at a private research university in the northeastern United States. Semi-structured interviews using complementary scripts were conducted separately with 42 participants over a 3 year period to probe their knowledge and understanding of responsible authorship and publication practices and learn how faculty and students entered into authorship decision-making intended to lead to the publication of peer-reviewed technical papers. Herein (...) the theoretical model for the negotiation of authorship developed through the analysis of these interviews is reported. The model identifies critical causal and intervening conditions responsible for the coping strategies faculty and students employ, which, in our study, appear to often produce unfortunate consequences for all involved. The undergraduate student researchers and their graduate student mentors interviewed in this study exhibited a limited understanding of authorship and the requirements for authorship in their research groups. The power differential between faculty and students, the students’ limited epistemic development, the busy-ness of the faculty, and the faculty’s failure to prioritize authorship have been identified as key factors inhibiting both undergraduate and graduate students from developing a deeper understanding of responsible authorship and publication practices. Implications for graduate education and undergraduate research are discussed, and strategies for helping all students to develop a deeper understanding of authorship are identified. (shrink)

Szabó follows Heim in viewing familiarity, rather than uniqueness, as the essence of the definite article, but attempts to derive both familiarity and uniqueness implications pragmatically, assigning a single semantic interpretation to both the definite and indefinite articles. I argue that if there is no semantic distinction between the articles, then there is no way to derive these differences between them pragmatically.

This book presents a powerful new film-philosophy through the cinema of Iranian director Abbas Kiarostami. Mathew Abbott argues that Kiarostami's films carry out cinematic thinking: they do not just illustrate pre-existing philosophical ideas, but do real philosophical work. Crossing the divide between analytic and continental philosophy, he draws on Ludwig Wittgenstein, Stanley Cavell, John McDowell, Alice Crary, Noël Carroll, Giorgio Agamben and Martin Heidegger, bringing out the thinking at work in Kiarostami's later films: Taste of Cherry, The Wind Will (...)

A defense of the modern family, in historical perspective, this book reconstructs political theory with the family in an important and honorable place. By reviewing critically both traditional and contemporary thought on the most special relationships—as well as current public policy issues relating to them—the author addresses concerns shared by professional and lay constituencies. Noting Tocqueville's observation of the American obsession with reevaluating and remodeling the family, Professor Abbott pleads for a balanced view. The development of liberal ambivalence toward (...) the family, along with radical hostility toward it, is clearly traced. For the most part the family was safely incorporated into political theory from Aristotle to Cicero and onward to Augustine and Aquinas until modern times. Then came the challenges of the rational individualists and the romantic individualists, followed by the attacks of social and psychological radicals. Some traditional criticisms of the family are shown to be soundly based, albeit less devastating than the critics supposed. As expanded in contemporary life, however, the great critics' revisionist models take on a fantastic quality. Here we are introduced to pleas for the "eroticization of children" and for freedom from "tyranny of reproductive biology." Proposals for new bureaucratic support structures appear with great frequency: professional guardians, children's camps, cloning hospitals. And people try to act out the roles prescribed for them by theorists who attempted "to set the solitary in new and different units." Liberals and radicals, the author argues, are infatuated with a "rights model," which "takes as its basis self-sufficient rational human beings"—at the expense of "solidarity among human beings." A tradition exists, Professor Abbott holds, that facilitates reconciliation between the modern family and the political order: pluralism. Pluralism is an attempt to balance individual autonomy and mutuality, decentralization and stratification, reform and tradition, reason and sentiment. Public policy in respect to schools, housing, health care, working conditions, and recreation should be designed to foster a pluralistic family-centered society. In line with this thesis the author offers a fresh perspective on such burning issues as abortion, sexual preference, alternative lifestyles, child abuse, and children's rights. _The Family on Trial _therefore is relevant to the concerns of social and behavioral scientists, the helping professions and the clergy, teachers and parents.

Like Spanish moss on a live oak tree, the scientific study of meaning in language has expanded in the last 100 years, and continues to expand steadily. In this essay I want to chart some central themes in that expansion, including their histories and their important figures. Our attention will be directed toward what is called 'formal semantics', which is the adaptation to natural language of analytical techniques from logic.[1] The first, background, section of the paper will survey the changing (...) attitudes of linguists toward semantics into the last third of the century. The second and third sections will examine current formal approaches to meaning. In the final section I will summarize some of the common assumptions of the approaches examined in the middle sections of the paper, sketch a few alternatives, and make some daring predictions.

Within the relevant semantics and pragmatics literature the terms “presupposition” and “conventional implicature” are used in a variety of different, but frequently overlapping, ways. The overlaps are perhaps not surprising, given that the two categories of conveyed meaning share the property of remaining constant in the scope of other operators—the property usefully characterize as projectivity. One of my purposes in this paper will be to try to clarify these different usages. In addition to that we will explore two additional properties (...) which are shared by some of these projective contents—strong contextual felicity, and neutralizability. The idea is to try to explain all three properties by taking into account information packaging. (shrink)

Donkey pronouns (e.g., it in Every farmer who owns a donkey beats it) are argued to have an interpretation more similar to a demonstrative phrase (e.g., . . . beats that donkey) than to any of the other alternatives generally considered (e.g., . . . the donkey(s) he owns, . . . a donkey he owns). Like the demonstrative phrase, the pronoun is not equivalent to Evans' E-type paraphrase, nor to either the weak or the strong reading sometimes claimed for (...) donkey sentences. A consequence is to narrow the range of formal analyses. (shrink)

Can there be higher level laws of nature even though everything is reducible to the fundamental laws of physics? The computer science notion of level of abstraction explains how there can be.

Orthologic is defined by weakening the axioms and rules of inference of the classical propositional calculus. The resulting Lindenbaum-Tarski quotient algebra is an orthoimplication algebra which generalizes the author's implication algebra. The associated order structure is a semi-orthomodular lattice. The theory of orthomodular lattices is obtained by adjoining a falsity symbol to the underlying orthologic or a least element to the orthoimplication algebra.

Research groups around the world are currently busy trying to invent new life in the laboratory, looking for extraterrestrial life, or making machines increasingly more life-like. In the case of astrobiology, any newly discovered life would likely be very old, but when discovered it would be new to us. In the case of synthetic organic life or life-like machines, humans will have invented life that did not exist before. Together, these endeavors amount to what we call the emerging plurality of (...) lives because we see a future where we are surrounded by, and interact with, life of many different origins, as well as entities that we have not traditionally seen as being alive. In the future these entities will likely possess properties that we so far have only associated with living beings, thereby transcending and perhaps blurring the borders between life and non-life.

There is congruence between Nietzsche’s philosophy of life and the biopolitical philosophy of Giorgio Agamben. For both philosophers the human animal possesses a divided relationship to its being alive. For both philosophers this division is of a political nature, such that membership in political community as we know it is conditional on the human animal’s alienation from its biological being. Both philosophers are also concerned with the possibility of transformation and, because of the connection they establish between politics and animality, (...) link this possibility to a change in the relationship between humans and their being alive. Yet both philosophers end up with an entirely different understanding of the nature of this change, and of its potential scope. This paper is an attempt at clarifying this disagreement between Nietzsche and Agamben, and with using it to come to a better understanding of the latter’s political ontology. It presents a reading of Kafka’s “The Burrow” in an attempt to show how Agamben’s concept of the anthropological machine challenges the Nietzschean program of the affirmation of life as will to power.

Background: The United Kingdom has the highest incarceration rate in Western Europe. It is known that women in prison are a vulnerable female population who are at risk of mental ill-health due to disadvantaged and chaotic life experiences. Accurate numbers of pregnant women held in UK prisons are not recorded, yet it is estimated that 6%–7% of the female prison population are at varying stages of pregnancy and around 100 babies are born to incarcerated women each year. There are limited (...) published papers that document the departure of the researcher following closure of fieldwork with women in prison. This article identifies the dilemmas and challenges associated with the closure of prison fieldwork through the interwoven reflections of the researcher. Departure scenarios are presented which illuminate moments of closure talk with five women, supported by participant reflections regarding abandonment and loss, making pledges for the future, self-affirmation, incidental add-ons at the end of an interview and red flags, alerting the researcher to potential participant harm through ill health or self-injury. Objectives: The primary intention of the study was to observe the pregnant woman’s experience with the English prison system through interviews with pregnant women and field observations of the environment. Research design: Ethnographic design enabled the researcher, a practising midwife, to engage with the prisoners’ pregnancy experiences in three English prisons, which took place over 10 months during 2015–2016. Data collection involved semi-structured, audio-recorded interviews with 28 female prisoners in England who were pregnant or had recently given birth while imprisoned, 10 members of staff and a period of non-participant observation. Follow-up interviews with 5 women were undertaken as their pregnancies progressed. Computerised qualitative data analysis software was used to generate and analyse pregnancy-related themes. Ethical considerations: Favourable ethical opinion was granted by National Offender Management Services through the Health Research Authority Integrated Research Application System and permission to proceed was granted by the University of Hertfordshire, UK. Findings: Thematic analysis enabled the identification of themes associated with the experience of prison pregnancy illuminating how prison life continues with little consideration for their unique physical needs, coping tactics adopted and the way women negotiate entitlements. On researcher departure from the field, the complex feelings of loss and sadness were experienced by both participants and researcher. Discussion: To leave the participant with a sense of abandonment following closure of fieldwork, due to the very nature of the closed environment, risks re-enactment of previous emotional pain of separation. Although not an ethical requirement, the researcher sought out psychotherapeutic supervision during the fieldwork phase with ‘Janet’, a forensic psychotherapist, which helped to highlight the need for careful closure of research/participant relationships with a vulnerable population. This article brings to the consciousness of prison researchers the need to minimise potential harm by carefully negotiating how to exit the field. Reflections of the researcher are interlinked with utterances from some participants to illustrate the types of departure behaviours. Conclusion: Closure of fieldwork and subsequent researcher departure involving pregnant women in prison requires careful handling to uphold the ethical research principle ‘do no harm’. (shrink)

Modern computing is generally taken to consist primarily of symbol manipulation. But symbols are abstract, and computers are physical. How can a physical device manipulate abstract symbols? Neither Church nor Turing considered this question. My answer is that the bit, as a hardware-implemented abstract data type, serves as a bridge between materiality and abstraction. Computing also relies on three other primitive—but more straightforward—abstractions: Sequentiality, State, and Transition. These physically-implemented abstractions define the borderline between hardware and software and between physicality and (...) abstraction. At a deeper level, asking how a physical device can interact with abstract symbols is the wrong question. The relationship between symbols and physical devices begins with the realization that human beings already know what it means to manipulate symbols. We build and program computers to do what we understand to be symbol manipulation. To understand what that means, consider a light switch. A light switch doesn’t turn a light on or off. Those are abstractions. Light switches don’t operate with abstractions. We build light switches, so that when flipped, the world is changed in such a way that we understand the light to be on or off. Similarly, we build computers to perform operations that we understand as manipulating symbols. (shrink)
