This book is a collection of secondary essays on America's most important philosophic thinkers—statesmen, judges, writers, educators, and activists—from the colonial period to the present. Each essay is a comprehensive introduction to the thought of a noted American on the fundamental meaning of the American regime.

ABSTRACTPrior experiments indicated that reading literary fiction improves mentalising performance relative to reading popular fiction, non-fiction, or not reading. However, the experiments had relatively small sample sizes and hence low statistical power. To address this limitation, the present authors conducted four high-powered replication experiments testing the causal impact of reading literary fiction on mentalising. Relative to the original research, the present experiments used the same literary texts in the reading manipulation; the same mentalising task; and the same kind of participant (...) samples. Moreover, one experiment was pre-registered as a direct replication. In none of the experiments did reading literary fiction have any effect on mentalising relative to control conditions. The results replicate earlier findings that familiarity with fiction is positively correlated with mentalising. Taken together, the present findings call into question whether a single session of rea... (shrink)

Moral philosophy has long been dominated by the aim of understanding morality and the virtues in terms of principles. However, the underlying assumption that this is the best approach has received almost no defence, and has been attacked by particularists, who argue that the traditional link between morality and principles is little more than an unwarranted prejudice. In Principled Ethics, Michael Ridge and Sean McKeever meet the particularist challenge head-on, and defend a distinctive view they call "generalism as a (...) regulative ideal.". (shrink)

This book provides an account of the nature of time, especially time's arrow and the role of entropy, at a semi-popular level. Special attention is given to statistical mechanics, the past hypothesis, and possible cosmological explanations thereof.

Quine's set theory, New Foundations, has often been treated as an anomaly in the history and philosophy of set theory. In this book, Sean Morris shows that it is in fact well-motivated, emerging in a natural way from the early development of set theory. Morris introduces and explores the notion of set theory as explication: the view that there is no single correct axiomatization of set theory, but rather that the various axiomatizations all serve to explicate the notion of (...) set and are judged largely according to pragmatic criteria. Morris also brings out the important interplay between New Foundations, Quine's philosophy of set theory, and his philosophy more generally. We see that his early technical work in logic foreshadows his later famed naturalism, with his philosophy of set theory playing a crucial role in his primary philosophical project of clarifying our conceptual scheme and specifically its logical and mathematical components.

I discuss "Poetic Naturalism" -- there is only one world, the natural world, but there are many ways of talking about it -- both as a general concept, and how it accounts for our actual world. I talk about emergence, fundamental physics, entropy and complexity, the origins of life and consciousness, and moral constructivism.

On one popular view, the general covariance of gravity implies that change is relational in a strong sense, such that all it is for a physical degree of freedom to change is for it to vary with regard to a second physical degree of freedom. At a quantum level, this view of change as relative variation leads to a fundamentally timeless formalism for quantum gravity. Here, we will show how one may avoid this acute ‘problem of time’. Under our view, (...) duration is still regarded as relative, but temporal succession is taken to be absolute. Following our approach, which is presented in more formal terms in, it is possible to conceive of a genuinely dynamical theory of quantum gravity within which time, in a substantive sense, remains. 1 Introduction1.1 The problem of time1.2 Our solution2 Understanding Symmetry2.1 Mechanics and representation2.2 Freedom by degrees2.3 Voluntary redundancy3 Understanding Time3.1 Change and order3.2 Quantization and succession4 Time and Gravitation4.1 The two faces of classical gravity4.2 Retaining succession in quantum gravity5 Discussion5.1 Related arguments5.2 Concluding remarks.

Companies offer ethics codes and training to increase employees’ ethical conduct. These programs can also enhance individual work attitudes because ethical organizations are typically valued. Socially responsible companies are likely viewed as ethical organizations and should therefore prompt similar employee job responses. Using survey information collected from 313 business professionals, this exploratory study proposed that perceived corporate social responsibility would mediate the positive relationships between ethics codes/training and job satisfaction. Results indicated that corporate social responsibility fully or partially mediated the (...) positive associations between four ethics program variables and individual job satisfaction, suggesting that companies might better manage employees’ ethical perceptions and work attitudes with multiple policies, an approach endorsed in the ethics literature.

This essay explores how the experience of National Socialism provoked German intellectuals to rethink elitist conventions in politics. It focuses on three figures in the town of Heidelberg—Alexander Mitscherlich, Dolf Sternberger, and Alfred Weber—as well as on a journal and a discussion forum that they established after 1945. Breaking with both mandarin and vanguardist traditions, they conceived a politics that neither transpired over the masses’ heads nor sought to organize them from above but rested on the people's participation from below. (...) Moreover, a correspondence existed between their thinking on democracy and the grassroots, extra-institutional activities they pursued in an attempt to realize what they called “publicness”. Finally, the essay relates such immediate postwar ideas and practices to these intellectuals’ stances toward West Germany after 1949 as well as to the discussion on “publicness” that unfolded there, as exemplified in Jürgen Habermas's early work.

Model theory is an important area of mathematical logic which has deep philosophical roots, many philosophical applications, and great philosophical interest in itself. The aim of this book is to introduce, organise, survey, and develop these connections between philosophy and model theory, for the benefit of philosophers and logicians alike.

Emmanuel Levinas has been Professor of Philosophy at the Sorbonne and the director of the Ecole Normale Israelite Orientale. Through such works as "Totality and Infinity" and "Otherwise than Being", he has exerted a profound influence on twentieth-century continental philosophy, providing inspiration for Derrida, Lyotard, Blanchot and Irigaray. "The Levinas Reader" collects, often for the first time in English, essays by Levinas encompassing every aspect of his thought: the early phenomenological studies written under the guidance and inspiration of Husserl and (...) Heidegger; the fully developed ethical critique of such totalizing philosophies; the pioneering texts on the moral dimension to aesthetics; the rich and subtle readings of the Talmud which are an exemplary model of an ethical, transcendental philosophy at work; the admirable meditations on current political issues. Sean Hand's introduction gives a complete overview of Levinas's work and situates each chapter within his general contribution to phenomenology, aesthetics, religion, politics and, above all, ethics. Each essay has been prefaced with a brief introduction presenting the basic issues and the necessary background, and suggesting ways to study the text further. (shrink)

To the best of our current understanding, quantum mechanics is part of the most fundamental picture of the universe. It is natural to ask how pure and minimal this fundamental quantum description can be. The simplest quantum ontology is that of the Everett or Many-Worlds interpretation, based on a vector in Hilbert space and a Hamiltonian. Typically one also relies on some classical structure, such as space and local configuration variables within it, which then gets promoted to an algebra of (...) preferred observables. We argue that even such an algebra is unnecessary, and the most basic description of the world is given by the spectrum of the Hamiltonian and the components of some particular vector in Hilbert space. Everything else—including space and fields propagating on it—is emergent from these minimal elements. (shrink)

A number of authors have argued recently that the content of perceptual experience can, and even must, be characterized in conceptual terms. Their claim, more precisely, is that every perceptual experience is such that, of necessity, its content is constituted entirely by concepts possessed by the subject having the experience. This is a surprising result. For it seems reasonable to think that a subject’s experiences could be richer and more fine-grained than his conceptual repertoire; that a subject might be able, (...) for example, to discriminate in experience more shades of colors than he has color concepts. The key move in their argument, therefore, is to articulate the conceptual content of experience using demonstrative, instead of general, concepts. For instance, these authors argue that the content of my perceptual experience of a particular shade of green is properly characterized in terms of the concept expressed by the linguistic utterance “that shade”. Even if I don’t possess a general concept for the shade I’m seeing—a concept of the kind typically expressed using color names like ‘chartreuse’ or ‘lime’—nevertheless, these authors argue, the content of the experience can still be characterized conceptually using a demonstrative concept that I do possess.

A corporate culture strengthened by ethical values and other positive business practices likely yields more favorable employee work responses. Thus, the purpose of this study was to assess the degree to which perceived corporate ethical values work in concert with group creativity to influence both job satisfaction and turnover intention. Using a self-report questionnaire, information was collected from 781 healthcare and administrative employees working at a multi-campus education-based healthcare organization. Additional survey data was collected from a comparative convenience sample of (...) 127 sales and marketing employees working for a variety of firms operating in the south-central United States. The results indicated that group creativity and corporate ethical values were positively related, and that both variables were associated with increased job satisfaction. Conversely, corporate ethical values and job satisfaction were associated with decreased turnover intention. Sales managers should create work cultures that precipitate increased ethical values and group creativity, and suggestions about how they may institutionalize these factors are provided. (shrink)

Most large companies and many smaller ones have adopted ethics codes, but the evidence is mixed as to whether they have a positive impact on the behavior of employees. We suggest that one way that ethics codes could contribute to ethical behavior is by influencing the perceptions that employees have about the ethical values of organizations. We examine whether a group of sales professionals in organizations with ethics codes perceive that their organizational context is more supportive of ethical behavior than (...) sales professionals in companies without codes. After accounting for the effect of several covariates, our results indicated that sales professionals employed in organizations with codes of ethics perceived their work environments to have more positive ethical values than did other sales professionals.

Ethics training is commonly cited as a primary method for increasing employees ethical decision making and conduct. However, little is known about how the presence of ethics training can enhance other components of an organization's ethical environment such as employees perception of company ethical values. Using a national sample of 313 business professionals employed in the United States, the relationship between ethics training and perceived organizational ethics was explored. The results of the analysis provide significant statistical support for the notion (...) that businesspersons employed in organizations that have formalized ethics training programs have more positive perceptions of their companies ethical context than do individuals employed in organizations that do not. The analysis also indicated that job satisfaction was related to employees attitudes about their ethical context. The managerial implications of the results are outlined, along with the limitations of the study and recommendations for future research. (shrink)

The purpose of this study was to assess the relationships among ethical context, organizational commitment, and person-organization fit using a sample of 304 young working adults. Results indicated that corporate ethical values signifying different cultural aspects of an ethical context were positively related to both organizational commitment and person-organization fit. Organizational commitment was also positively related to person-organization fit. The findings suggest that the development and promotion of an ethical context might enhance employees' workplace experiences, and companies should consider adopting (...) ethical policies that support principled conduct, punish unethical actions, and increase individual perceptions of an ethical company environment.

This study explored several proposed relationships among professional ethical standards, corporate social responsibility, and the perceived role of ethics and social responsibility. Data were collected from 313 business managers registered with a large professional research association with a mailed self-report questionnaire. Mediated regression analysis indicated that perceptions of corporate social responsibility partially mediated the positive relationship between perceived professional ethical standards and the believed importance of ethics and social responsibility. Perceptions of corporate social responsibility also fully mediated the negative relationship (...) between perceived professional ethical standards and the subordination of ethics and social responsibility. The results suggested that professions should develop ethical standards to encourage social responsibility, since these actions are associated with enhanced employee ethical attitudes. (shrink)

The passage above comes from the opening pages of Merleau-Ponty’s essay on Edmund Husserl. It proposes a risky interpretive principle. The main feature of this principle is that the seminal aspects of a thinker’s work are so close to him that he is incapable of articulating them himself. Nevertheless, these aspects pervade the work, give it its style, its sense and its direction, and therefore belong to it essentially. As Martin Heidegger writes, in a passage quoted by Merleau-Ponty: " The (...) greater the work of a thinker – which in no way coincides with the breadth and number of writings – the richer is what is un-thought in this work, which means, that which emerges in and through this work as having not yet been thought. 2 " The goal of Merleau-Ponty’s essay, he says, is “to evoke this un-thought-of element in Husserl’s thought”. 3.

This paper sets out a predicative response to the Russell-Myhill paradox of propositions within the framework of Church’s intensional logic. A predicative response places restrictions on the full comprehension schema, which asserts that every formula determines a higher-order entity. In addition to motivating the restriction on the comprehension schema from intuitions about the stability of reference, this paper contains a consistency proof for the predicative response to the Russell-Myhill paradox. The models used to establish this consistency also model other axioms (...) of Church’s intensional logic that have been criticized by Parsons and Klement: this, it turns out, is due to resources which also permit an interpretation of a fragment of Gallin’s intensional logic. Finally, the relation between the predicative response to the Russell-Myhill paradox of propositions and the Russell paradox of sets is discussed, and it is shown that the predicative conception of set induced by this predicative intensional logic allows one to respond to the Wehmeier problem of many non-extensions.

Organizations constitute morally-complex environments, requiring organization members to possess levels of moral courage sufficient to promote their ethical action, while refraining from unethical actions when faced with temptations or pressures. Using a sample drawn from a military context, we explored the antecedents and consequences of moral courage. Results from this four-month field study demonstrated that authentic leadership was positively related to followers’ displays of moral courage. Further, followers’ moral courage fully mediated the effects of authentic leadership on followers’ ethical and (...) pro-social behaviors. Theoretical and practical implications for further integrating the work on moral courage, authentic leadership and ethics are discussed. (shrink)

Frege's Grundgesetze was one of the 19th century forerunners to contemporary set theory which was plagued by the Russell paradox. In recent years, it has been shown that subsystems of the Grundgesetze formed by restricting the comprehension schema are consistent. One aim of this paper is to ascertain how much set theory can be developed within these consistent fragments of the Grundgesetze, and our main theorem shows that there is a model of a fragment of the Grundgesetze which defines a (...) model of all the axioms of Zermelo-Fraenkel set theory with the exception of the power set axiom. The proof of this result appeals to G\"odel's constructible universe of sets, which G\"odel famously used to show the relative consistency of the continuum hypothesis. More specifically, our proofs appeal to Kripke and Platek's idea of the projectum within the constructible universe as well as to a weak version of uniformization (which does not involve knowledge of Jensen's fine structure theory). The axioms of the Grundgesetze are examples of abstraction principles, and the other primary aim of this paper is to articulate a sufficient condition for the consistency of abstraction principles with limited amounts of comprehension. As an application, we resolve an analogue of the joint consistency problem in the predicative setting. (shrink)

Previous research indicates that ethical ideologies, issue-contingencies, and social context can impact ethical reasoning in different business situations. However, the manner in which these constructs work together to shape different steps of the ethical decision-making process is not always clear. The purpose of this study was to address these issues by exploring the influence of idealism and relativism, perceived moral intensity in a decision-making situation, and social context on the recognition of an ethical issue and ethical intention. Utilizing a sales-based (...) scenario and multiple ethics measures included on a self-report questionnaire, data were collected from a regional sample of business students, most of whom had modest work experience. The results indicated that perceived moral intensity was associated with increased ethical issue recognition and ethical intention. Idealism was also associated with increased ethical issue recognition, and relativism was associated with decreased ethical intention. Social consensus was positively related to ethical issue recognition and intention, while competitive context was inversely related to ethical intention. Finally, ethical issue recognition was associated with increased ethical intention. Idealism, moral intensity, social consensus, and work experience worked together as predictors of ethical issue recognition, whereas recognition of an ethical issue, relativism, moral intensity, social consensus, and competitive context worked together to predict ethical intention.

In this study, we examined students' attitudes toward cheating and whether they would report instances of cheating they witnessed. Data were collected from three educational institutions in Singapore. A total of 518 students participated in the study. Findings suggest that students perceived cheating behaviors involving exam-related situations to be serious, whereas plagiarism was rated as less serious. Cheating in the form of not contributing one's fair share in a group project was also perceived as a serious form of academic misconduct, (...) although a majority of the students admitted having engaged in such behavior. With regard to the prevalence of academic cheating, our findings suggest that students are morally ambivalent about academic cheating and are rather tolerant of dishonesty among their peers. On the issue of whether cheating behaviors should be reported, our findings revealed that a majority of students chose to take the expedient measure of ignoring the problem rather than to blow the whistle on their peers. Implications of our findings are discussed. (shrink)

I begin by examining a recent debate between John McDowell and Christopher Peacocke over whether the content of perceptual experience is non-conceptual. Although I am sympathetic to Peacocke’s claim that perceptual content is non-conceptual, I suggest a number of ways in which his arguments fail to make that case. This failure stems from an over-emphasis on the "fine-grainedness" of perceptual content - a feature that is relatively unimportant to its non-conceptual structure. I go on to describe two other features of (...) perceptual experience that are more likely to be relevant to the claim that perceptual content is non-conceptual. These features are 1) the dependence of a perceived object on the perceptual context in which it is perceived and 2) the dependence of a perceived property on the object it is perceived to be a property of.

Previous work suggests that moral intensity and the perceived importance of an ethical issue can influence individual ethical decision making. However, prior research has not explored how the various dimensions of moral intensity might differentially affect PIE, or how moral intensity might function together with (or in the presence of) PIE to influence ethical decision making. In addition, prior work has also not adequately investigated how the operational context of an organization, which may embody conditions or practices that create barriers (...) to ethical decision making, may differ from other functional areas of an organization. Consequently, this study investigated the relationships among moral intensity, perceived ethical issue importance, and three stages of the ethical reasoning process: recognition of an ethical issue, ethical judgment, and ethical intention. Using an internet-based, self-report survey containing two operations management scenarios and various ethics measures, information was collected from business professionals working for a Midwestern financial services organization. The hierarchical regression results indicated that some dimensions of moral intensity were positively related to PIE, ethical issue recognition, and ethical judgment, and that PIE was associated with increased ethical issue recognition and ethical judgment. The steps of ethical reasoning were also positively interrelated. (shrink)

There you are at the opera house. The soprano has just hit her high note – a glassshattering high C that fills the hall – and she holds it. She holds it. She holds it. She holds it. She holds it. She holds the note for such a long time that after a while a funny thing happens: you no longer seem only to hear it, the note as it is currently sounding, that glass-shattering high C that is loud and (...) high and pure. In addition, you also seem to hear something more. It is difficult to express precisely what this extra feature is. One is tempted to say, however, that the note now sounds like it has been going on for a very long time. Perhaps it even sounds like a note that has been going on for too long. In any event, what you hear no longer seems to be limited to the pitch, timbre, loudness, and other strictly audible qualities of the note. You seem in addition to experience, even to hear, something about its temporal extent. (shrink)

A crucial part of the contemporary interest in logicism in the philosophy of mathematics resides in its idea that arithmetical knowledge may be based on logical knowledge. Here an implementation of this idea is considered that holds that knowledge of arithmetical principles may be based on two things: (i) knowledge of logical principles and (ii) knowledge that the arithmetical principles are representable in the logical principles. The notions of representation considered here are related to theory-based and structure-based notions of representation (...) from contemporary mathematical logic. It is argued that the theory-based versions of such logicism are either too liberal (the plethora problem) or are committed to intuitively incorrect closure conditions (the consistency problem). Structure-based versions must on the other hand respond to a charge of begging the question (the circularity problem) or explain how one may have a knowledge of structure in advance of a knowledge of axioms (the signature problem). This discussion is significant because it gives us a better idea of what a notion of representation must look like if it is to aid in realizing some of the traditional epistemic aims of logicism in the philosophy of mathematics.

While a number of studies have examined the impact of gender/sex on ethical decision-making, the findings of this body of research do not provide consistent answers. Furthermore, very few of these studies have incorporated cross-cultural samples. Consequently, this study of 222 American and Spanish business executives explored sex differences in ethical judgments and intentions to act ethically. While no significant differences between males and females were found with respect to ethical judgments, females exhibited higher intentions to act more ethically than (...) males. This difference was true of both U.S. and Spanish executives. Further research is warranted to develop a clearer understanding of the linkage between ethical judgment and intention to act in an ethical manner. These findings have implications for global firms, particularly regarding codes of conduct and ethics training. (shrink)

Management plays an important role in reinforcing ethics in organizations. To support this aim, managers must use incentive and goal programs in ethical ways. This study examines experimentally the potential ethical costs associated with incentive-driven and goal-induced employee behavior from a managerial perspective. In a quasi-experimental setting, 243 MBA students with significant professional work experience evaluated a hypothetical employee’s ethical behavior under incentive pay systems modeled on a business case. In the role of the employee’s manager, participants evaluated the ethicality (...) of the employee’s incentive-driven and goal-induced ethical/unethical behavior and the outcomes of behavior, with consequences that were either favorable or unfavorable to the organization. The results indicated that participants discounted the ethical considerations of incentive-driven and goal-induced behavior when consequences were favorable to the organization. Participants’ morals and outcome orientations were also significantly related to their ethical judgments and intentions to intervene. The implications of these findings for research and practice are discussed. (shrink)

This study assesses the relationships among unethical corporate values, bullying experiences, psychopathy, and selling professionals’ ethical evaluations of bullying. Information was collected from national/regional samples of selling professionals. Results indicated that unethical values, bullying, and psychopathy were positively interrelated. Psychopathy and unethical values were negatively associated with moral intensity, while moral intensity was positively related to ethical issue importance. Psychopathy and unethical values were negatively related to issue importance, and issue importance and moral intensity were positively related to ethical judgment. (...) Finally, ethical judgment and moral intensity were positively linked to ethical intention; psychopathy was negatively associated with ethical intention. (shrink)

The French philosopher Maurice Merleau-Ponty claims that there are two distinct ways in which we can understand the place of an object when we are visually apprehending it. The first involves an intentional relation to the object that is essentially cognitive or can serve as the input to cognitive processes; the second irreducibly involves a bodily set or preparation to deal with the object. Because of its essential bodily component, Merleau-Ponty calls this second kind of understanding ‘motor intentional’. In this (...) paper I consider some phenomenological, conceptual, and cognitive neuro-scientific results that help to elucidate and defend the distinction between intentional and motor intentional activity. I go on to argue that motor intentional activity has a logical structure that is essentially distinct from that of the more canonical kinds of intentional states. In particular, the characteristic logical distinction between the content and the attitude of an intentional state does not carry over to the motor intentional case. (shrink)

Role conflict occurs when a job possesses inconsistent expectations incongruent with individual beliefs, a situation that precipitates considerable frustration and other negative work outcomes. Increasing interest in processes that reduce role conflict is, therefore, witnessed. With the help of information collected from a large sample of individuals employed at an education-based healthcare institution, this study identified several factors that might decrease role conflict, namely mindfulness and organizational ethics. In particular, the results indicated that mindfulness was associated with decreased role conflict, (...) and that perceived ethical values and a shared ethics code were associated with decreased role conflict and increased mindfulness. Despite the study's limitations, these findings imply that companies might better manage role conflict through the development of mindfulness and organizational ethics. (shrink)

It is commonplace in discussions of modern cosmology to assert that the early universe began in a special state. Conventionally, cosmologists characterize this fine-tuning in terms of the horizon and flatness problems. I argue that the fine-tuning is real, but these problems aren't the best way to think about it: causal disconnection of separated regions isn't the real problem, and flatness isn't a problem at all. Fine-tuning is better understood in terms of a measure on the space of trajectories: given (...) reasonable conditions in the late universe, the fraction of cosmological histories that were smooth at early times is incredibly tiny. This discussion helps clarify what is required by a complete theory of cosmological initial conditions. (shrink)

This paper presents new constructions of models of Hume's Principle and Basic Law V with restricted amounts of comprehension. The techniques used in these constructions are drawn from hyperarithmetic theory and the model theory of fields, and formalizing these techniques within various subsystems of second-order Peano arithmetic allows one to put upper and lower bounds on the interpretability strength of these theories and hence to compare these theories to the canonical subsystems of second-order arithmetic. The main results of this paper (...) are: (i) there is a consistent extension of the hyperarithmetic fragment of Basic Law V which interprets the hyperarithmetic fragment of second-order Peano arithmetic, and (ii) the hyperarithmetic fragment of Hume's Principle does not interpret the hyperarithmetic fragment of second-order Peano arithmetic, so that in this specific sense there is no predicative version of Frege's Theorem.

Many recent writers in the philosophy of mathematics have put great weight on the relative categoricity of the traditional axiomatizations of our foundational theories of arithmetic and set theory. Another great enterprise in contemporary philosophy of mathematics has been Wright's and Hale's project of founding mathematics on abstraction principles. In earlier work, it was noted that one traditional abstraction principle, namely Hume's Principle, had a certain relative categoricity property, which here we term natural relative categoricity. In this paper, we show (...) that most other abstraction principles are not naturally relatively categorical, so that there is in fact a large amount of incompatibility between these two recent trends in contemporary philosophy of mathematics. To better understand the precise demands of relative categoricity in the context of abstraction principles, we compare and contrast these constraints to stability-like acceptability criteria on abstraction principles, the Tarski-Sher logicality requirements on abstraction principles studied by Antonelli and Fine, and supervaluational ideas coming out of Hodes' work.

This book explores the important yet neglected relationship between the philosophy of time and the temporal structure of perceptual experience. It examines how time structures perceptual experience and, through that structuring, the ways in which time makes perceptual experience trustworthy or erroneous. -/- Sean Power argues that our understanding of time can determine our understanding of perceptual experience in relation to perceptual structure and perceptual error. He examines the general conditions under which an experience may be sorted into different (...) kinds of error such as illusions, hallucinations, and anosognosia. Power also argues that some theories of time are better than others at giving an account of the structure and errors of perceptual experience. He makes the case that tenseless theory and eternalism more closely correspond to experience than tense theory and presentism. Finally, the book includes a discussion of the perceptual experience of space and how tenseless theory and eternalism can better support the problematic theory of naïve realism. -/- Philosophy of Time and Perceptual Experience originally illustrates how the metaphysics of time can be usefully applied to thinking about experience in general. It will appeal to those interested in the philosophy of time and debates about the trustworthiness of experience. (shrink)

Philosophical writing on gratitude displays a pronounced preference for targeted gratitude (A’s being grateful to B for x) over propositional gratitude (A’s being grateful that p), treating the latter as a poor, less interesting cousin of the former, when it treats it at all. This paper challenges and attempts to rectify the relegation of propositional gratitude to second-class status. It argues that propositional gratitude is not only not reducible to targeted gratitude but indeed is more basic than it and that (...) propositional gratitude is morally important because of its conceptual connections to the virtue of humility.
