The arbitrariness of a signal has long been seen as a theoretically important but difficult to pin down notion. In this article, we suggest there are at least two different notions of arbitrariness at play in philosophical and scientific debates concerning the use of arbitrary signals, and work towards improved analyses of both. We then consider how these different types of arbitrariness can co-occur and come apart. Finally, we examine the connections between these two types of arbitrariness and the cognitive (...) complexity of signal users with an eye towards better evaluating one possible form of human-nonhuman communicative continuity. We show that each type of arbitrariness bears its own nuanced relationship to cognitive complexity, demonstrating the theoretical importance of keeping these two notions separate. (shrink)

Modeling work by Brian Skyrms and others in recent years has transformed the theoretical role of David Lewis's 1969 model of signaling. The latter can now be understood as a minimal model of communication in all its forms. In this article, we explain how the Lewis model has been generalized, and consider how it and its variants contribute to ongoing debates in several areas. Specifically, we consider connections between the models and four topics: The role of common interest in communication, (...) signaling within the organism, meaning, and the evolution of human communication and language.

Diane Vaughan’s analysis of the causes of the Challenger accident suggests ways to apply science and technology studies to the teaching of engineering ethics. By sensitizing future engineers to the ongoing construction of risk during mundane engineering practice, we can better prepare them to address issues of public health, safety, and welfare before they require heroic intervention. Understanding the importance of precedents, incremental change, and fallible engineering judgment in engineering design may help them anticipate potential threats to public safety arising (...) from routine aspects of workplace culture. We suggest modifications of both detailed case studies on engineering disasters and hypothetical, ethical dilemmas employed in engineering ethics classes. Investigating the sociotechnical aspects of engineering practice can improve the initial recognition of ethical problems in real-world settings and provide an understanding of the role of workplace organization and culture in facilitating or impeding remedial action.

According to one currently influential line of thinking, the evolution of ostensive communication was a prerequisite for the evolution of human language. In this article, I distinguish between a strong and a weak version of this view and offer a sustained argument against the former. More specifically, the strong version of this view would have it that ostensive communication was a prerequisite not just for the evolution of fully modern language but for any language-like system of communication. I argue that (...) this version is too strong: I show how some distinctive and important features of language may well have been assembled prior to the evolution of ostensive communication. Put another way, I argue that a protolanguage before ostensive communication scenario is a real possibility. I conclude by briefly arguing that such an evolutionary scenario coheres better with archaeological evidence from the early Pleistocene as well as evidence from developmental psychology pertaining to the nature of our mind reading abilities.

This article addresses the question of whether early Pleistocene hominins are plausibly viewed as having possessed a protolanguage, that is, a communication system exemplifying some but not all of the distinctive features of fully modern human language. I argue that the answer is “yes,” mounting evidence from the early Pleistocene “lithics niche.” More specifically, I first describe a cognitive platform that I think would have been sufficient, given appropriate socio-ecological conditions, for the creation and retention of a protolanguage. Then, using (...) archaeological evidence pertaining to hominin lithic behavior from the early Pleistocene, I attempt to make plausible the idea that each of these cognitive abilities were in fact in place by this point in hominin evolutionary history and also that the requisite socio-ecological conditions were satisfied.

Logical models of argument formalize commonsense reasoning while taking process and computation seriously. This survey discusses the main ideas which characterize di erent logical models of argument. It presents the formal features of a few main approaches to the modeling of argumentation. We trace the evolution of argumentationfrom the mid-80's, when argumentsystems emerged as an alternative to nonmonotonic formalisms based on classical logic, to the present, as argument is embedded in di erent complex systems for real-world applications, and allows more (...) formal work to be done in different areas, such as AI & Law, case-based reasoning and negotiation among intelligent agents.

Some recent physiological data indicate that the “subjective timing” of experiences can be “automatically referred backwards in time” to represent a sequence of events even though the earlier portions of associated neurophysiological activity are themselves insufficient to elicit the experience of any sensation. The challenge, then, is to explain how subjects can experience what they do in the reported ways when, if one looked just at certain neurophysiological activity, it would seem that perhaps subjects should report their sensations differently. The (...) phenomenon has seemed sufficiently remarkable to the neurobiologist John Eccles to count as evidence for mind-body dualism. This dualistic interpretation has resulted in a spirited attack by P. S. Churchland on both the physiological research and the dualistic interpretation. Her attack resulted in an equally spirited defense of the research by the primary investigator, B. Libet, where he reaffirmed his more guarded interpretation that “the temporal discrepancy creates relative difficulties for identity theory, but that these are not insurmountable”. In turn, Churchland has defended her criticism of Libet's research so that, for her, Libet's hypothesis remains “infirm and unconfirmed”. (shrink)

We conducted a rapid review and quantitative summary of meta-analyses that have examined interventions which can be used by individuals during quarantine and social distancing to manage anxiety, depression, stress and subjective well-being. A literature search yielded 34 meta-analyses (total number of studies k = 1,390, n = 145,744) that were summarized. Overall, self-guided interventions showed small to medium effects in comparison to control groups. In particular, self-guided therapeutic approaches (including cognitive-behavioral, mindfulness, and acceptance-based interventions), selected positive psychology interventions, and (...) multi-component and activity-based interventions (music, physical exercise) showed promising evidence for effectiveness. Overall, self-guided interventions on average did not show the same degree of effectiveness as traditional guided individual or group therapies. There was no consistent evidence of dose effects, baseline differences and differential effectiveness of eHealth interventions. More research on the effectiveness of interventions in diverse cultural settings is needed. (shrink)

This paper utilizes Scott domains (continuous lattices) to provide a mathematical model for the use of idealized and approximately true data in the testing of scientific theories. Key episodes from the history of science can be understood in terms of this model as attempts to demonstrate that theories are monotonic, that is, yield better predictions when fed better or more realistic data. However, as we show, monotonicity and truth of theories are independent notions. A formal description is given of the (...) pragmatic virtues of theories which are monotonic. We also introduce the stronger concept of continuity and show how it relates to the finite nature of scientific computations. Finally, we show that the space of theories also has the structure of a Scott domain. This result provides an analysis of how one theory can be said to approximate another. (shrink)

This article explores the issue of rebuilding an organization’s reputation following an ethical scandal. We divide our discussion into four parts. First, we discuss the concept of reputation. We note its relevance to today’s organizations, offer several contemporary definitions along with highlighting its benefits and downsides. In the second section, we offer the work of anthropologist, Victor Turner, on social drama along with other views on organizational efforts to rebuild their reputation to include reputation management routines. In the third section, (...) Turner’s redressive actions are integrated with Edgar Schein’s leadership mechanisms for building or changing culture to provide further understanding of organizational efforts to rebuild reputation following ethical scandals. Finally, in the fourth section of the article, we extend the integration of the Turner and Schein work with single- and double-loop redressive actions for rebuilding reputation. (shrink)

Synthetic biology makes use of genetic and other materials derived from modern biological life forms to design and construct novel synthetic organisms. Artificial organisms are not constructed from parts of existing biological organisms, but from non-biological materials. Artificial and synthetic organisms are artefactual organisms. Here we are concerned with the non-instrumental value of such organisms. More specifically, we are concerned with the extent to which artefactual organisms have natural value, inherent worth and intrinsic value. Our conclusions are largely supportive of (...) the value of artefactual organisms. However, they do not constitute a comprehensive ethical evaluation of them. (shrink)

Analyzed F. Galton's data on the sensory, psychomotor, and physical attributes of 1,639 females and 4,849 males. The reliability of the measures, developmental trends in mean scores, correlations of the measures with age, correlations among measures, occupational differences in scores, and sibling correlations are described. Developmental trends during later childhood, adolescence, and early maturity are compared to those described in contemporary developmental psychological literature.

Nothing seems to follow strictly from 'X believes that p'. But if we reinterpret it to mean: 'X can consistently be described as consistently believing p'--which roughly renders, I think, Hintikka's notion of "defensibility"--we can get on with the subject, freed from the inhibitions of descriptive adequacy. But defensibility is neither necessary nor sufficient for truth: it tells us little, therefore, about the concept of belief on which it is based. It cannot, in particular, specify necessary conditions for the consistent (...) ascription of belief--as opposed to rational belief. If there are no such conditions, all belief ascriptions must be treated as atomic: which is implausible. If there are some, they must be settled on before an account of consistency can be complete. The reason is simple: it is that we have beliefs about our own beliefs. A set of first order beliefs is consistent if they can all be true together; but it is a lesson of Moore's paradox that consistency of second-order beliefs requires additional constraints. If someone both believes that p and that he does not believe that p, the propositions he believes might all be true together, yet he is inconsistent. And the characterization of second order consistency will remain incomplete, so long as nothing is said about the consistency of first order belief ascriptions. Suppose someone says and believes: "I am inconsistent: I believe both p and ~p." This is "indefensible": but is it insight, or nonsense? Breast-beating of this sort is guaranteed success: something he believes is bound to be false. But that remains diagnostically frustrating: is he inconsistent because what he said is true, or on the contrary because it is inconsistent? (shrink)

All these specialist aspects of one life are different facets of the intellectual diamond which scintillates in the huge quarry of The Bertrand Russell Archives at McMaster University, Hamilton, Ontario. This is the quintessential man, the bundle of contradictions passionately dedicated to intellect, at times carrying the rational argument to irrational extremes; the natural-born emotional adventurer forever hampered by orphaned youth and too-early marriage. This Russell in the round is greater than the sum of his constituent parts, a man of (...) epic proportions, struggling through a lifetime beset with frustration and near-disaster; in youth the constitutional sceptic, in old age the sometimes splendid figure with "courage never to submit or yield.".

While the term “metacognition” is sometimes used to refer to any form of thinking about thinking, in cognitive psychology, it is typically reserved for thinking about one’s own thinking, as opposed to thinking about others’ thinking. How metacognition in this more specific sense relates to other-directed mindreading is one of the main theoretical issues debated in the literature. This article considers the idea that we make use of the same or a largely similar package of resources in conceptually interpreting our (...) own mind as we do in interpreting others’. I assume that a capacity for other-directed mindreading is minimally shared with our great-ape relatives, but I argue that the architecture of this system had to be substantially modified before it could efficiently and adaptively be turned inwards on one’s own mind. I contend that an important piece of the overall evolutionary explanation here likely concerns selection pressures arising from the domain of conversational interaction. Specifically, drawing on work carried out in the human interaction studies tradition (e.g., conversation analysis), I argue that the smooth to-and-fro of conversational interaction can be seen to heavily depend on metacommunicative capacities, which, in turn, are underpinned by metacognitive capacities. I conclude with a thumbnail sketch of an evolutionary account of the emergence of these metacognitive capacities in the human line. Their appearance and spread – whether via genes, cultural learning, or more likely, some combination of the two – helps to explain the transition from great-ape communication to human conversation.

What is an inference rule? This question does not have a unique answer. One usually finds two distinct standard answers in the literature; validity inference $(\sigma \vdash_\mathrm{v} \varphi$ if for every substitution $\tau$, the validity of $\tau \lbrack\sigma\rbrack$ entails the validity of $\tau\lbrack\varphi\rbrack)$, and truth inference $(\sigma \vdash_\mathrm{t} \varphi$ if for every substitution $\tau$, the truth of $\tau\lbrack\sigma\rbrack$ entails the truth of $\tau\lbrack\varphi\rbrack)$. In this paper we introduce a general semantic framework that allows us to investigate the notion of inference (...) more carefully. Validity inference and truth inference are in some sense the extremal points in our framework. We investigate the relationship between various types of inference in our general framework, and consider the complexity of deciding if an inference rule is sound, in the context of a number of logics of interest: classical propositional logic, a nonstandard propositional logic, various propositional modal logics, and first-order logic.

Kinship plays a foundational role in organizing human social behavior on both local and more global scales. Hence, any adequate account of the evolution of human sociality must include an account of the evolution of human kinship. This article aims to make progress on the latter task by providing a few key pieces of an evolutionary model of kinship systems. The article is especially focused on the connection between primate social cognition and the origins of kinship systems. I argue that (...) early conceptions of kinship in our line were very likely scaffolded by preexisting forms of primate social cognition. It was only later, as linguistic resources increased in our line, and as human social life grew more complex, that these conceptions came to resemble kin categories as we now know them. I conclude by situating “kin cognition” within a broader cognitive science framework for studying capacities that reflect both innate knowledge and human cultural learning. (shrink)

The paper begins with an example of the accounting treatment afforded an Indefeasible Rights Use Swap by Global Crossing. The case presents a typical example of ways in which accounting firms contributed to the ethical scandals of the early 21st century. While the behavior of Arthur Andersen, the accounting company in the case, might have met the letter of the law, we argue that it violated "the spirit of the law," which can be discovered by looking at the legitimate goals (...) of a company which give it its ethical direction and the responsibilities of the accounting professionals who serve the company and the general public. Those professional responsibilities are determined by looking at the legitimate function those professionals fulfill in the economy. A further claim is that Andersen and other accounting firms are motivated to abandon the responsibilities derived from pursuing their proper goals by falling into the trap of accumulating wealth for its own sake. We argue that the ultimate responsibility of internal auditors is to develop statements that give as reasonably true and fair a picture of the financial situation to any user having a claim to that knowledge. Further we argue that the major responsibilities of the external auditor are: first, to be responsible to the using public for evaluating financial statements and declaring that they represent a fair picture of the financial situation of a company, and second, to be a watchdog of financial markets and call into question irregular practices that would distort those pictures. Such due professional care requires the auditor to exercise "professional skepticism": an attitude that includes a questioning mind and a critical assessment of audit evidence. The paper concludes by giving particular examples of how Arthur Andersen LLP failed to meet those responsibilities. (shrink)

The idea that cognition makes use of one or more “languages of thought” remains central to much cognitive-scientific and philosophical theorizing. And yet, virtually no attention has been paid to the question of how a language of thought might evolve in the first place. In this article, I take some steps towards addressing this issue. With the aid of the so-called Sender–Receiver framework, I elucidate a family of distinctions and processes which enable us to see how languages of thought might (...) evolve via a series of small, incremental changes. While much work doubtlessly remains to be done in this area, I hope to at least show that there need be nothing mysterious about the existence of languages of thought on evolutionary grounds.

The present research was guided by the important need for a diversion from an economistic to a humanistic management perspective of sustainability. It concentrates on the current importance of digital strategic communication, particularly regarding the concept of corporate sustainability in the context of the conflict arena of the oil industry. The focus is on the comparison of the persuasive effectiveness of the framings of corporate versus activist NGO website communications and their impacts on the perception of the triple pillars of (...) sustainability and, corporate greenwashing with respect to a proposed bituminous oil pipeline in Canada. The results of these pro and con messages were analyzed within the Elaboration Likelihood Model demonstrating a “non expert” peripheral route to a positive persuasion from exposure to the corporate communication versus an “expert” central route to a negative persuasion from the activist NGO communication. Subsequent exposure to the opposite website communication further emphasized the predominance of a negative persuasion based on both groups now being motivated as “expert” viewers of these strategic communications, leading to an important perception of greenwashing by participants resulting from vague claims, visual and linguistic contents of the corporate communication versus the mainly verifiable factual ones in that of the activist NGO.

This article examines some recent work by Berwick and Chomsky as presented in their book Why Only Us? Language and Evolution. As I understand them, Berwick and Chomsky’s overarching purpose is to explain how human language could have arisen in so short an evolutionary period. After articulating their strategy, I argue that they fall far short of reaching this goal. A co-evolutionary scenario linking the mechanisms that realize the language system, both with one other and with cognitive mechanisms capable of (...) exploiting linguistic expressions, is surely unavoidable. And yet this is precisely what Berwick and Chomsky in effect rule out. (shrink)

Although the first human embryonic stem cells were produced in 1998, the direction of U.S. policy on stem cell research was set nearly 20 years earlier when the recommendations of a congressionally established Ethics Advisory Board were ignored by the Reagan administration. Thus began an unprecedented and unparalleled 30-year-long history of political intrusions in an area of scientific and biomedical research that has measurable impacts on the health of Americans. Driving these intrusions were religiously informed public policy positions that have (...) usually escaped critical ethical analysis. Here I record my own encounters with this history of intrusions and the thinking behind them.My most abrupt encounter with the politics of stem cell research occurred on September 6, 2006, at a hearing of the Senate Subcommittee on Labor, Health and Human Services and Related Agencies, chaired by Senator Arlen Specter. Just a week before, scientists at Advanced Cell Technology, a small Massachusetts biotech company, had published a paper in the journal Nature in which they described a method for extracting stem cells from early human embryos while leaving the embryos intact and viable. As head of ACT’s Ethics Advisory Board, I had supported this research. (shrink)

Perceptual completion fills the gap for discrete perception to become continuous. Similarly, dynamic perceptual completion provides an experience of dynamic continuity. Our recent discovery of the ‘happening’ element of DPC completes the total experience for dynamism in the flow of time. However, a phenomenological explanation for these experiences is essential. The Snapshot Hypotheses especially the Dynamic Snapshot View provides the most comprehensive explanation. From that understanding the ‘two times’ problem can be addressed. The static time of spacetime cosmologies has been (...) irreconcilable with the dynamic FOT. Dismissing the FOT as an illusion is unsatisfactory. Therefore, we provide four hypotheses for the TTP.1) Since cosmological static time demands that all events are discrete, DPC elements for dynamism should likewise be expected to be discrete and accounted for by a snapshot phenomenology such as the DSV. 2) If temporality can be demonstrated to be similar to apparent motion by being a snapshot phenomenon and not demanding temporal extension it would confirm the DSV and permit reconciliation with static time. 3) If the ‘present moment’ is subjective as static time theories suggest, it should be possible experimentally for an observer to choose his own ‘present’ by moving to various points in the past with the aid of virtual reality. 4) If dynamism e.g. motion can be precluded without significant information loss or violating physics principles it is a cognitive add-on, thereby contradicting non-static time theories which suggest that time is ‘real.’ We confirm those hypotheses.

We do a quantitative analysis of modal logic. For example, for each Kripke structure M, we study the least ordinal μ such that for each state of M, the beliefs of up to level μ characterize the agents' beliefs (that is, there is only one way to extend these beliefs to higher levels). As another example, we show the equivalence of three conditions, that on the face of it look quite different, for what it means to say that the agents' (...) beliefs have a countable description, or putting it another way, have a "countable amount of information". The first condition says that the beliefs of the agents are those at a state of a countable Kripke structure. The second condition says that the beliefs of the agents can be described in an infinitary language, where conjunctions of arbitrary countable sets of formulas are allowed. The third condition says that countably many levels of belief are sufficient to capture all of the uncertainty of the agents (along with a technical condition). The fact that all of these conditions are equivalent shows the robustness of the concept of the agents' beliefs having a "countable description". (shrink)

With higher education around the world in a period of extreme flux, this volume explores its underlying philosophy, a core element of the ongoing debate. Offering a diverse range of perspectives from an international selection of renowned scholars of higher education, the book is full of imaginative insights that add up to a substantive contribution to the discussion. As universities attempt to adapt to a new environment characterized by stiff international competition, networked remote learning, burgeoning student numbers, and comparative performance (...) assessment, how we conceptualize the purpose and ethos of our higher learning institutions is more important than ever. This publication features a multitude of distinctive approaches that illuminate potential solutions to the complex issues universities must grapple with in these uncertain times. Rather than espousing a singular philosophical approach, the editors have assembled views from across the spectrum and from differing national contexts, representing a multidisciplinary response to the situation. This collection of papers aims thus to inspire fresh developments in the way we think about the complexities of, and options available to, higher education. (shrink)

A vast literature has developed probing the law's aversion to statistical/probability evidence in general and its rejection of naked statistical evidence in particular. This literature rests on false premises. At least so far as US law is concerned, there is no general aversion to statistical forms of proof and even naked statistics are admissible and sufficient for a verdict when the evidentiary proffer meets the normal standards of admissibility, the most important of which is reliability. The belief to the contrary (...) rests upon a series of mistakes: most importantly, mismodeling of the structure of legal systems and the nature of common law decision making. Contributing to these mistakes is the common methodology in this literature of relying on weird hypotheticals that mismodel the underlying legal relations and contain impossible epistemological demands. Collectively, these phenomena have distracted attention from issues that actually affect real legal systems. (shrink)
