Epistemic decision theorists aim to justify Bayesian norms by arguing that these norms further the goal of epistemic accuracy—having beliefs that are as close as possible to the truth. The standard defense of Probabilism appeals to accuracy dominance: for every belief state that violates the probability calculus, there is some probabilistic belief state that is more accurate, come what may. The standard defense of Conditionalization, on the other hand, appeals to expected accuracy: before the evidence is in, one should expect (...) to do better by conditionalizing than by following any other rule. We present a new argument for Conditionalization that appeals to accuracy‐dominance, rather than expected accuracy. Our argument suggests that Conditionalization is a rule of coherence: plans that conflict with Conditionalization don't just prescribe bad responses to the evidence; they also give rise to inconsistent attitudes.

He then proceeds with an examination of the picture theory developed by Wittgenstein, Carnap, and Goodman, and concludes with an examination of Patricia Churchland, Ruth Millikan, Robert Cummins, and Mark Rollins. The use of the historical development of representationalism to pose a central problem in contemporary cognitive science is unique.

The cosmological and teleological argument both start with some contingent feature of the actual world and argue that the best or only explanation of that feature is that it was produced by an intelligent and powerful supernatural being. The cosmological argument starts with a general feature, such as the existence of contingent being or the presence of motion and uses some version of the Principle of Sufficient Reason to conclude that this feature must have an explanation. The debate then focuses (...) on two points: first, whether the PSR in question is true, and second, whether the explanation must involve God or at least some God-like being. The teleological argument begins with a general feature of the cosmos judged to have value, such as the existence of intelligent life or the presence of order in the universe, and argues, usually inductively but sometimes deductively, that this feature is to be explained by the agency of a powerful supernatural being. Here, the debate tends to focus on whether there are alternate naturalistic explanations, such as Darwinian evolution. (shrink)

We consider the set of jumps below a Turing degree, given by JB={x':x≤a}, with a focus on the problem: Which recursively enumerable degrees a are uniquely determined by JB? Initially, this is motivated as a strategy to solve the rigidity problem for the partial order R of r.e. degrees. Namely, we show that if every high2 r.e. degree a is determined by JB, then R cannot have a nontrivial automorphism. We then defeat the strategy—at least in the form presented—by constructing (...) pairs a0, a1 of distinct r.e. degrees such that JB=JB within any possible jump class {x:x'=c}. We give some extensions of the construction and suggest ways to salvage the attack on rigidity. (shrink)

We investigate the complexity of various combinatorial theorems about linear and partial orders, from the points of view of computability theory and reverse mathematics. We focus in particular on the principles ADS (Ascending or Descending Sequence), which states that every infinite linear order has either an infinite descending sequence or an infinite ascending sequence, and CAC (Chain-AntiChain), which states that every infinite partial order has either an infinite chain or an infinite antichain. It is well-known that Ramsey's Theorem for pairs (...) (RT₂²) splits into a stable version (SRT₂²) and a cohesive principle (COH). We show that the same is true of ADS and CAC, and that in their cases the stable versions are strictly weaker than the full ones (which is not known to be the case for RT₂² and SRT₂²). We also analyze the relationships between these principles and other systems and principles previously studied by reverse mathematics, such as WKL₀, DNR, and BΣ₂. We show, for instance, that WKL₀ is incomparable with all of the systems we study. We also prove computability-theoretic and conservation results for them. Among these results are a strengthening of the fact, proved by Cholak, Jockusch, and Slaman, that COH is Π₁¹-conservative over the base system RCA₀. We also prove that CAC does not imply DNR which, combined with a recent result of Hirschfeldt, Jockusch, Kjos-Hanssen, Lempp, and Slaman, shows that CAC does not imply SRT₂² (and so does not imply RT₂²). This answers a question of Cholak, Jockusch, and Slaman. Our proofs suggest that the essential distinction between ADS and CAC on the one hand and RT₂² on the other is that the colorings needed for our analysis are in some way transitive. We formalize this intuition as the notions of transitive and semitransitive colorings and show that the existence of homogeneous sets for such colorings is equivalent to ADS and CAC, respectively. We finish with several open questions. (shrink)

Do dissociations imply independent systems? In the memory field, the view that there are independent implicit and explicit memory systems has been predominantly supported by dissociation evidence. Here, we argue that many of these dissociations do not necessarily imply distinct memory systems. We review recent work with a single-system computational model that extends signal-detection theory (SDT) to implicit memory. SDT has had a major influence on research in a variety of domains. The current work shows that it can be broadened (...) even further in its range of application. Indeed, the single-system model that we present does surprisingly well in accounting for some key dissociations that have been taken as evidence for independent implicit and explicit memory systems.

Current models of autobiographical memory suggest that self-identity guides autobiographical memory retrieval. Further, the capacity to recall the past and imagine one’s self in the future can influence social problem solving. We examined whether manipulating self-identity, through an induction task in which students were led to believe they possessed high or low self-efficacy, impacted episodic specificity and content of retrieved and imagined events, as well as social problem solving. Compared to individuals in the low self efficacy group, individuals in the (...) high self efficacy group generated past and future events with greater specificity, positive words, and self-efficacious statements, and also performed better on social problem solving indices. A lack of episodic detail for future events predicted poorer performance on social problem solving tasks. Strategies that increase perceived self-efficacy may help individuals to selectively construct a past and future that aids in negotiating social problems. (shrink)

This study investigated whether employee perceptions of corporate social responsibility (CSR) were associated with the presence of Corporate Psychopaths in corporations. The article states that, as psychopaths are 1% of the population, it is logical to assume that every large corporation has psychopaths working within it. To differentiate these people from the common perception of psychopaths as being criminals, they have been called “Corporate Psychopaths” in this research. The article presents quantitative empirical research into the influence of Corporate Psychopaths on (...) four perceptual measures of CSR and three further measures of organizational commitment to employees. The article explains who Corporate Psychopaths are and delineates the measures of CSR and organizational commitment to employees that were used. It then outlines the research conducted among 346 corporate employees in Australia in 2008. The reliability of the instrument used is commented on favorably in terms of its statistical reliability and its face and external validity. Results of the research are described showing the highly significant and negative influence of Corporate Psychopaths on all of the measures of CSR and of organizational commitment to employees used in the research. When Corporate Psychopaths are present in leadership positions within organizations, employees are less likely to agree with views that: the organization does business in a socially desirable manner; does business in an environmentally friendly manner and that the organization does business in a way that benefits the local community. Also, when Corporate Psychopaths are present in leadership positions within organizations, employees are significantly less likely to agree that the corporation does business in a way that shows commitment to employees, significantly less likely to feel that they receive due recognition for doing a good job, to feel that their work was appreciated and to feel that their efforts were properly rewarded. The article argues that academics and researchers in the area of CSR cannot ignore the influence of individual managers. This is particularly the case when those managers have dysfunctional personalities, or are actually psychopaths. The article further argues that the existence of Corporate Psychopaths should be of interest to those involved in corporate management and corporate governance because their presence influences the way corporations are run and how corporations affect society and the environment.

While the notion of establishing a value for human life may be uncomfortable for some, we argue that it is a fundamental requirement for many aspects of public policy. We compare a number of approaches which have been traditionally relied on to make estimations. Also, we provide an exercise which provides an unusual, but we hope provocative, perspective on the evaluation of human life.

We show that the theory of the partial ordering of the computably enumerable degrees in any given nontrivial interval is undecidable and has uncountably many 1-types.

This article presents a theoretical model of the self processes involved in autobiographical memories and proposes competing hypotheses for the role of visual perspective in autobiographical memory retrieval. Autobiographical memories can be retrieved from either the 1st person perspective, in which individuals see the event through their own eyes, or from the 3rd person perspective, in which individuals see themselves and the event from the perspective of an external observer. A growing body of research suggests that the visual perspective from (...) which a memory is retrieved has important implications for a person’s thoughts, feelings, and goals, and is integrally related to a host of self-evaluative processes. We review the relevant research literature, present our theoretical model, and outline directions for future research. (shrink)

Many of today's ads work by arousing the viewer's emotions. Although emotion-arousing ads are widely used and are commonly thought to be effective, their careless use produces a side-effect: the psychoactive ad. A psychoactive ad is any emotion-arousing ad that can cause a meaningful, well-defined group of viewers to feel extremely anxious, to feel hostile toward others, or to feel a loss of self-esteem. We argue that, because some ill-conceived psychoactive ads can cause harm, ethical issues must arise during their (...) production. Current pretesting methods cannot identify the potentially psychoactive ads; therefore, we offer some tentative guidelines for reducing the number of viewers harmed by psychoactive ads. (shrink)

Milton Friedman has argued that corporations have no responsibility to society beyond that of obeying the law and maximizing profits for shareholders. Individuals may have social responsibilities according to Friedman, but not corporations.When executives make contributions to address social problems in the name of the corporation, they are doing so with other people''s (shareholders'') money. The responsibility of corporate executives is a fiduciary one, to serve as an agent for the corporation''s shareholders, and to uphold shareholders'' trust, which requires executives (...) to maximize the return to their shareholders, who can then, if they choose, contribute their own money to worthy causes.

By an incomplete sentence we shall understand a declarative sentence that can be used, without variation in its meaning, to make different statements in different contexts. Although the point deserves supporting argument, which we will not provide, sentences whose grammatical subjects are indexical expressions or demonstratives are obvious, plausible examples of incomplete sentences. Uttered in one context the sentence ‘He is ill’ may be used to make one statement, for example, that George is ill, while in another context the very (...) same sentence may be used to make a quite different statement, for example, that Paul is ill.

One of the greatest of modern philosophers, on a par with his contemporary John Locke, Leibniz was born in Leipzig in 1646, died in Hanover in 1716. He was a leading figure in European intellectual circles, and the founder of the Academy of Berlin. His strange, complex metaphysical system established him as the third of the great 'Rationalists', after Descartes and Spinoza. Along with the 'New System', his most famous philosophical works are the Discourse of Metaphysics and Monadology. He also (...) made important contributions to logic, mathematics, theology, jurisprudence, and history.Gathered here for the first time are all the key texts in a crucial debate in modern philosophy, centred on Leibniz's famous 1695 essay, the `New System of the Nature of Substances and their Communication'. In this classic essay Leibniz introduced to a broad European readership the strikingly original metaphysical ideas he had come to a decade earlier. His 'system' became increasingly famous and drew him into discussion and development of these ideas, both in public and in private, with a variety of thinkers: Simon Foucher; Henri Basbage de Beauval; Francois Lamy; Isaac Jacquelot; the Englishwoman Damaris Masham; Pierre Desmaizeaux; René Joseph de Tournemine; and most notably the great French philosopher and scholar Pierre Bayle.

Since the late 1980s, the human genetics and genomics research community has been promising to usher in a “new paradigm for health care”—one that uses molecular profiling to identify human genetic variants implicated in multifactorial health risks. After the completion of the Human Genome Project in 2003, a wide range of stakeholders became committed to this “paradigm shift,” creating a confluence of investment, advocacy, and enthusiasm that bears all the marks of a “scientific/intellectual social movement” within biomedicine. Proponents of this (...) movement usually offer four ways in which their approach to medical diagnosis and health care improves upon current practices, arguing that it is more “personalized,” “predictive,” “preventive,” and “participatory” than the medical status quo. Initially, it was personalization that seemed to best sum up the movement's appeal. By 2012, however, powerful opinion leaders were abandoning “personalized medicine” in favor of a new label: “precision medicine.” The new label received a decisive seal of approval when, in January 2015, President Obama unveiled plans for a national “precision medicine initiative” to promote the development and use of genomic tools in health care.

Blair equates the constructs of working memory (WM), executive function, and general fluid intelligence (gF). We argue that there is good reason not to equate these constructs. We view WM and gF as separable but highly related, and suggest that the mechanism behind the relationship is controlled attention – an ability that is dependent on normal functioning of the prefrontal cortex.
