This book addresses some basic questions about intrinsic value: What is it? What has it? What justifies our beliefs about it? In the first six chapters the author defends the existence of a plurality of intrinsic goods, the thesis of organic unities, the view that some goods are 'higher' than others, and the view that intrinsic value can be explicated in terms of 'fitting' emotional attitudes. The final three chapters explore the justification of our beliefs about intrinsic value, including coherence (...) theories and the idea that some value beliefs are warranted on the basis of emotional experience. Professor Lemos defends the view that some value beliefs enjoy 'modest' a priori justification. The book is intended primarily for professional philosophers and their graduate students working in ethics, value theory and epistemology. (shrink)

Some philosophers have adopted both a commonsense approach to the theory of knowledge and held that some epistemic principles are knowable a priori. Roderick Chisholm is a prominent example of a philosopher who does both. In The Problem of the Criterion, Chisholm holds that in attempting to discover criteria of evidence we should begin with particular commonsense examples of knowledge, such as I know that I have two hands and I know that there are other people. According to Chisholm, our (...) knowledge of these particular epistemic facts does not depend upon our knowing criteria of evidence or knowledge. Moreover, we may reject various criteria of evidence and knowledge because they do not fit with these particular epistemic facts. Thus, according to Chisholm, we may reject the empiricist criterion of knowledge held by Locke and Hume because it implies that we do not know things that we do in fact know, because it conflicts with our commonsense epistemic beliefs.

There is a long tradition in moral philosophy which maintains that a necessary condition for moral goodness is that one act from a sense of duty. Kant is perhaps the best known and most discussed representative of this view, but one finds others prior to Kant, such as Butler and Price, and Kant's contemporaries, such as Reid, expressing similar ideas. Price, for example writes, ". . . what I have chiefly insisted on, is, that we characterize as virtuous no actions (...) flowing merely from instinctive desires, or from any principle except a regard to virtue itself.'' In this paper, I shall defend a version of this thesis. (shrink)

Jacques Derrida's insistence on submitting politics to the test of undecidability elicits the common accusation that an aporetic form of thought can only end in dubious conclusions concerning the pressing matter of politics and that no normative claims can emerge from a thought of radical undecidability. In this paper, I articulate the structural undecidability (aporia) that constitutes politics according to Derrida, the manner in which this structural undecidability elicits judgments, and the importance for critique of not ignoring it. In particular, (...) this structural undecidability is articulated within the event of foundation of any state or set of social relations by way of a declarative act. In addition, the aporetic structure of the political renders visible the essential relationship between (revealed) religion and politics. Ultimately, due to a necessary reference to an ultimate authority at any event of foundation, the political is always already theologico-political in character. (shrink)

The requirement of gauge invariance for the Schwinger-DeWitt equations, interpreted as a manifestly covariant quantum theory for the evolution of a system in spacetime, implies the existence of a five-dimensional pre-Maxwell field on the manifold of spacetime and “proper time” τ. The Maxwell theory is contained in this theory; integration of the field equations over τ restores the Maxwell equations with the usual interpretation of the sources. Following Schwinger's techniques, we study the Green's functions for the five-dimensional hyperbolic field equations (...) for both signatures ± [corresponding to O(4, 1) or O(3, 2) symmetry of the field equations] of the proper time derivative. The classification of the Green's functions follows that of the four-dimensional theory for “massive” fields, for which the “mass” squared may be positive or negative, respectively. The Green's functions for the five-dimensional field are then given by the Fourier transform over the “mass” parameter. We derive the Green's functions corresponding to the principal part ΔP and the homogeneous function Δ 1 ; all of the Green's functions can be expressed in terms of these, as for the usual field equations with definite mass. In the O(3, 2) case, the principal part function has support for x2⩾τ2, corresponding to spacelike propagation, as well as along the light cone x2=0 (for τ=0). There can be no transmission ofinformation in spacelike directions, with this propagator, since the Maxwell field, obtained by integration over τ, does not contain this component of the support. Measurements are characterized by such an integration. The spacelike field therefore can dynamically establish spacelike correlations. (shrink)

To assess the impact of selected murals in the Workers’ Hospital in Santiago on different groups of clients, a quantitative and qualitative approach, including a semantic differential scale, was applied. The sample was composed of 120 subjects—40 patients, 40 visitors and 40 hospital staff. Appreciation of the paintings and assessment of the benefit of each painting varied widely. Differences in perceptions according to age, gender and educational level were not significant. Over two-thirds of the sample had a positive appreciation of (...) the murals and considered them beneficial. Differences in perception relate to personal characteristics of the subjects and are also associated with certain characteristics of the murals, such as location, or the structure and style of the work. This study, the first of its kind in Chile, provides grounds for the development of an art-for-health policy in the future, showing that most people are willing to participate by giving their opinions and assessments.

This paper examines the Stark effect, as a first order perturbation of manifestly covariant hydrogen-like bound states. These bound states are solutions to a relativistic Schrödinger equation with invariant evolution parameter, and represent mass eigenstates whose eigenvalues correspond to the well-known energy spectrum of the nonrelativistic theory. In analogy to the nonrelativistic case, the off-diagonal perturbation leads to a lifting of the degeneracy in the mass spectrum. In the covariant case, not only do the spectral lines split, but they acquire (...) an imaginary part which is linear in the applied electric field, thus revealing induced bound state decay in first order perturbation theory. This imaginary part results from the coupling of the external field to the non-compact boost generator. In order to recover the conventional first order Stark splitting, we must include a scalar potential term. This term may be understood as a fifth gauge potential, which compensates for dependence of gauge transformations on the invariant evolution parameter. (shrink)

Recently, in the framework of a relativistic quantum theory with invariant evolution parameter, solutions have been found for the two-body bound state, whose mass spectrum agrees with the nonrelativistic Schrödinger energy spectrum. In this paper, we study the radiative transitions of these states in the dipole approximation and find that the selection rules are identical with those of the usual nonrelativistic theory, expressed in a manifestly covariant form. In addition to the transverse and longitudinal polarizations of the nonrelativistic theory, we (...) find a “scalar” transition, induced by the relative time coordinate, which is of the same type as the longitudinal transition, expressing the Lorentz covariance of the theory.

Although interesting, the hypotheses proposed by Phillips & Silverstein lack unifying structure both in specific mechanisms and in cited evidence. They provide little to support the notion that low-level sensory processing and high-level cognitive coordination share dynamic grouping by synchrony as a common processing mechanism. We suggest that more realistic large-scale modeling at multiple levels is needed to address these issues.

We propose a novel phenomenon, attention contagion, defined as the spread of attentive (or inattentive) states among members of a group. We examined attention contagion in a learning environment in which pairs of undergraduate students watched a lecture video. Each pair consisted of a participant and a confederate trained to exhibit attentive behaviors (e.g., leaning forward) or inattentive behaviors (e.g., slouching). In Experiment 1, confederates sat in front of participants and could be seen. Relative to participants who watched the lecture (...) with an inattentive confederate, participants with an attentive confederate: (a) self-reported higher levels of attentiveness, (b) behaved more attentively (e.g., took more notes), and (c) had better memory for lecture content. In Experiment 2, confederates sat behind participants. Despite confederates not being visible, participants were still aware of whether confederates were acting attentively or inattentively, and participants were still susceptible to attention contagion. Our findings suggest that distraction is one factor that contributes to the spread of inattentiveness (Experiment 1), but this phenomenon apparently can still occur in the absence of distraction (Experiment 2). We propose an account of how (in)attentiveness spreads across students and discuss practical implications regarding how learning is affected in the classroom. (shrink)

Hierarchical Bayesian models provide an account of Bayesian inference in a hierarchically structured hypothesis space. Scientific theories are plausibly regarded as organized into hierarchies in many cases, with higher levels sometimes called ‘paradigms’ and lower levels encoding more specific or concrete hypotheses. Therefore, HBMs provide a useful model for scientific theory change, showing how higher-level theory change may be driven by the impact of evidence on lower levels. HBMs capture features described in the Kuhnian tradition, particularly the idea that higher-level (...) theories guide learning at lower levels. In addition, they help resolve certain issues for Bayesians, such as scientific preference for simplicity and the problem of new theories. (shrink)

This study modelled associations between gender, ruminative cognitive style, alcohol use, and the time course of negative affect over the course of 43,111 random assessments in the natural environment. Participants completed 49 days of experience sampling over 1.3 years. The data indicated that rumination at baseline was positively associated with alcohol dependence symptoms at baseline as well as higher negative affect over the course of the study. Consistent with negative reinforcement models, drinking served to decrease the persistence of negative affect (...) from moment to moment. However, this ameliorative effect of drinking was evident only among women, suggesting an increased risk for negative reinforcement driven drinking behaviour. In addition, rumination appeared to counteract the desired effects of alcohol on mood among women. This suggests that women who ruminate more may be motivated to consume larger amounts of alcohol to achieve the desired effects. Overall, the results indicate that ruminative cognitive style and the persistence of negative affect from moment to moment may reflect an individual vulnerability for the development of alcohol use disorder especially among women.

Combinatorial operations on sets are almost never well defined on Turing degrees, a fact so obvious that counterexamples are worth exhibiting. The case we focus on is the symmetric-difference operator; there are pairs of degrees for which the symmetric-difference operation is well defined. Some examples can be extracted from the literature, e.g. from the existence of nonzero degrees with strong minimal covers. We focus on the case of incomparable r.e. degrees for which the symmetric-difference operation is well defined.

Bi-directional differences in social communication and behavior can contribute to poor interactions between autistic and non-autistic people, which in turn may reduce social opportunities for autistic adults and contribute to poor outcomes. Historically, interventions to improve social interaction in autism have focused on altering the behaviors of autistic people and have ignored the role of NA people. Recent efforts to improve autism understanding among NA adults via training have resulted in more favorable views toward autistic people, yet it remains unknown (...) whether these benefits extend to real-world interactions between autistic and NA people. The current study explores whether a brief autism acceptance training program can improve social interactions between autistic and NA adults. Thirty-nine NA males were randomly assigned to complete AAT or a no-training control condition, then participated in a 5-min unstructured conversation with an unfamiliar autistic male. Following the conversation, participants rated their perceptions of interaction quality, first impressions of their partner, and their interest in future interactions with their partner. In dyads where the NA individual completed AAT, both the autistic and NA person endorsed greater future interest in hanging out with their partner relative to dyads in which the NA adult did not complete AAT. However, other social interaction outcomes, including ratings of interaction quality and first impressions of autistic partners, largely did not differ between training and no-training conditions, and assessments of the interaction were largely unrelated for autistic and NA partners within dyads. Results also indicated that NA participants, but not autistic participants, demonstrated substantial correspondence between evaluations of their partner and the interaction, suggesting that autistic adults may place less weight on trait judgments when assessing the quality of an interaction. These findings suggest that the brief AAT for NA adults used in this study may increase mutual social interest in real-world interactions between NA and autistic adults, but more systematic changes are likely needed to bridge divides between these individuals. Future work with larger, more diverse samples is recommended to further explore whether interventions targeting NA adults are beneficial for improving autistic experiences within NA social environments.

Social cognition, social skill, and social motivation have been extensively researched and characterized as atypical in autistic people, with the assumption that each mechanistically contributes to the broader social interaction difficulties that diagnostically define the condition. Despite this assumption, research has not directly assessed whether or how these three social domains contribute to actual real-world social interaction outcomes for autistic people. The current study administered standardized measures of social cognition, social skill, and social motivation to 67 autistic and 58 non-autistic (...) adults and assessed whether performance on these measures, both individually and relationally between dyadic partners, predicted outcomes for autistic and NA adults interacting with unfamiliar autistic and NA partners in a 5 minute unstructured “get to know you” conversation. Consistent with previous research, autistic adults scored lower than NA adults on the three social domains and were evaluated less favorably by their conversation partners. However, links between autistic adults' performance on the three social domains and their social interaction outcomes were minimal and, contrary to prediction, only the social abilities of NA adults predicted some interaction outcomes within mixed diagnostic dyads. Collectively, results suggest that reduced performance by autistic adults on standardized measures of social cognition, social skill, and social motivation do not correspond in clear and predictable ways with their real-world social interaction outcomes. They also highlight the need for the development and validation of more ecological assessments of autistic social abilities and the consideration of relational dynamics, not just individual characteristics, when assessing social disability in autism.
