This debate, principally between myself (Nigel Thomas) and Patrick Hayes, the well known computer scientist and Artificial Intelligence researcher, took place through the internet mailing list for the discussion of the scientific study of consciousness, PSYCHE-D (moderated by Patrick Wilken), which is associated with the on-line journal PSYCHE. The discussion touches on the various different senses in which the expression "mental image" may be used, the underlying cognitive mechanisms of imagery, and the relevance of an understanding of imagery (...) to the understanding of conscious thought, and thought in general. As the debate became rather 'unthreaded' on the list, following it through this page may help the reader to better understand what was going on. (shrink)

This chapter examines a little-known movement to make the Our Lady of Perpetual Help icon the patroness of the proceedings of the Second Vatican Council. Begun by American Redemptorists, it sought to integrate a Marian piety into the conciliar ethos, but one that was decidedly cross-cultural and ecumenical. Explicit in its mission for unity between Roman Catholics and the separated churches of the East, the movement promoted the icon as the key to repairing centuries-old wounds. Insofar as 2015 begins the (...) sesquicentennial year of the icon’s association with Redemptorists, as well as its value as an ecumenical tool, the author explores whether OLPH can lend new impetus for unity between Orthodox and Catholics ahead of the proposed joint synod in 2025.

Readable and accessible collection of papers re thinking machines.

This volume explores how Catholicism began and continues to open its doors to the wider world and to other confessions in embracing ecumenism, thanks to the vision and legacy of the Second Vatican Council. It explores such themes as the twentieth century context preceding the council; parallels between Vatican II and previous councils; its distinctively pastoral character; the legacy of the council in relation to issues such as church-world dynamics, as well as to ethics, social justice, economic activity. Several chapters (...) discuss the role of women in the church before, during, and since the council. Others discern inculturation in relation to Vatican II. The book also contains a wide and original range of ecumenical considerations of the council, including by and in relation to Free Church, Reformed, Orthodox, and Anglican perspectives. Finally, it considers the Council’s ongoing promise and remaining challenges with regard to ecumenical issues, including a groundbreaking essay on the future of ecumenical dialogue by Cardinal Walter Kasper.

Beyond the Ancient Quarrel brings together contributions from leading scholars to explore the boundaries between literature, philosophy, and literary criticism in the work of J.M. Coetzee.

Sebbene la ricchezza espressiva e la versatilità della scrittura di J.M. Coetzee si prestino ad una varietà di studi e considerazioni che riescono a coinvolgere molteplici discipline, solo i saggi che compongono il presente volume si impongono come un primo importante studio volto a comprendere, in maniera più sistematica, l’ampia pluralità di voci che caratterizza la critica coetziana. Il volume, dunque, riesce a superare le analisi meramente settoriali e unilaterali perché, cogliendo le pro...

When certain formal symbol systems (e.g., computer programs) are implemented as dynamic physical symbol systems (e.g., when they are run on a computer) their activity can be interpreted at higher levels (e.g., binary code can be interpreted as LISP, LISP code can be interpreted as English, and English can be interpreted as a meaningful conversation). These higher levels of interpretability are called "virtual" systems. If such a virtual system is interpretable as if it had a mind, is such a "virtual (...) mind" real? This is the question addressed in this "virtual" symposium, originally conducted electronically among four cognitive scientists: Donald Perlis, a computer scientist, argues that according to the computationalist thesis, virtual minds are real and hence Searle's Chinese Room Argument fails, because if Searle memorized and executed a program that could pass the Turing Test in Chinese he would have a second, virtual, Chinese-understanding mind of which he was unaware (as in multiple personality). Stevan Harnad, a psychologist, argues that Searle's Argument is valid, virtual minds are just hermeneutic overinterpretations, and symbols must be grounded in the real world of objects, not just the virtual world of interpretations. Computer scientist Patrick Hayes argues that Searle's Argument fails, but because Searle does not really implement the program: A real implementation must not be homuncular but mindless and mechanical, like a computer. Only then can it give rise to a mind at the virtual level. Philosopher Ned Block suggests that there is no reason a mindful implementation would not be a real one. (shrink)

_"One of the most important political books of 2018."—Rod Dreher, ___American Conservative__ Of the three dominant ideologies of the twentieth century—fascism, communism, and liberalism—only the last remains. This has created a peculiar situation in which liberalism’s proponents tend to forget that it _is _an ideology and not the natural end-state of human political evolution. As Patrick Deneen argues in this provocative book, liberalism is built on a foundation of contradictions: it trumpets equal rights while fostering incomparable material inequality; its (...) legitimacy rests on consent, yet it discourages civic commitments in favor of privatism; and in its pursuit of individual autonomy, it has given rise to the most far-reaching, comprehensive state system in human history. Here, Deneen offers an astringent warning that the centripetal forces now at work on our political culture are not superficial flaws but inherent features of a system whose success is generating its own failure.

In this paper I argue for an association between impurity and explanatory power in contemporary mathematics. This proposal is defended against the ancient and influential idea that purity and explanation go hand-in-hand (Aristotle, Bolzano) and recent suggestions that purity/impurity ascriptions and explanatory power are more or less distinct (Section 1). This is done by analyzing a central and deep result of additive number theory, Szemerédi’s theorem, and various of its proofs (Section 2). In particular, I focus upon the radically impure (...) (ergodic) proof due to Furstenberg (Section 3). Furstenberg’s ergodic proof is striking because it utilizes intuitively foreign and infinitary resources to prove a finitary combinatorial result and does so in a perspicuous fashion. I claim that Furstenberg’s proof is explanatory in light of its clear expression of a crucial structural result, which provides the “reason why” Szemerédi’s theorem is true. This is, however, rather surprising: how can such intuitively different conceptual resources “get a grip on” the theorem to be proved? I account for this phenomenon by articulating a new construal of the content of a mathematical statement, which I call structural content (Section 4). I argue that the availability of structural content saves intuitive epistemic distinctions made in mathematical practice and simultaneously explicates the intervention of surprising and explanatorily rich conceptual resources. Structural content also disarms general arguments for thinking that impurity and explanatory power might come apart. Finally, I sketch a proposal that, once structural content is in hand, impure resources lead to explanatory proofs via suitably understood varieties of simplification and unification (Section 5).

While the subjective experience of insight during problem solving is a common occurrence, an understanding of the processes leading to solution remains relatively uncertain. The goal of this study was to investigate the restructuring patterns underlying solution of a creative problem, and how providing cues to solution may alter the process. Results show that both providing cues to solution and analyzing problem solving performance on an aggregate level may result in restructuring patterns that appear incremental. Analysis of performance on an (...) individual level provides evidence for insight-like solution patterns. However, no evidence is found for a relationship between an individual’s restructuring pattern and their subjective experience of insight during problem solving. (shrink)

: In recent literature supporting a hybrid view between metaethical cognitivism and noncognitivist expressivism, much has been made of an analogy between moral terms and pejoratives. The analogy is based on the plausible idea that pejorative slurs are used to express both a descriptive belief and a negative attitude. The analogy looks promising insofar as it encourages the kinds of features we should want from a hybrid expressivist view for moral language. But the analogy between moral terms and pejorative slurs (...) is also problematic. In this paper, I argue for two main ways in which we should distinguish between two different types of pejorative terms: slurs, on the one hand, and what I call general pejorative terms, on the other. I examine the problems with the analogy between slurs and moral terms and conclude that general pejorative terms like ‘jerk’ are a better candidate on which to model the potential dual-use behavior of moral terms. So if hybrid theorists are looking for a dual-use model for moral language, they should be careful to base their analogies on general pejoratives, rather than slurs. (shrink)

Within the field of aesthetics, there are several approaches to answering what affects how and whether an individual engages with a particular art or aesthetic object. Two theories that attempt to come to a solution on this issue are theories of attunement and attachment which respectively argue that one’s engagement is primarily affected by one’s attunement or attachment, through a system of values, beliefs, and associations, to an object. While these theories are successful in responding to a variety of cases, (...) individually, they leave something to be desired explicatively, and, in light of this, I will develop in this essay an alternative that centres itself on the character of the aesthetic subject which will do the work of both approaches without having to make any taxing conceptual commitments.

Social entrepreneurship activity continues to surge tremendously in market and economic systems around the world. Yet, social entrepreneurship theory and understanding lag far behind its practice. For instance, the nature of the entrepreneurial discovery phenomenon, a critical area of inquiry in general entrepreneurship theory, receives no attention in the specific context of social entrepreneurship. To address the gap, we conceptualize social entrepreneurial discovery based on an extension of corporate social responsibility into social entrepreneurship contexts. We develop a model that emphasizes (...) mobilization and timing as underpinnings of social entrepreneurial discovery and offer distinct conceptual aspects and theoretic propositions instrumental to future social entrepreneurship research.

How are we to make sense of madness and psychosis? For most of us the words conjure up images from television and newspapers of seemingly random, meaningless violence. It is something to be feared, something to be left to the experts. But is madness best thought of as a medical condition? Psychiatrists and the drug industry maintain that psychoses are brain disorders amenable to treatment with drugs, but is this actually so? There is no convincing evidence that the brain is (...) disordered in psychosis, yet governments across the world are investing huge sums of money on mental health services that take for granted the idea that psychosis is an illness to be treated with medication. Although some people who use mental health services find medication helpful, many do not, and resist the idea that their experiences are symptoms of illnesses like schizophrenia. Consequently they are forced into having treatment against their wishes. So, how do we make sense of this situation? Postpsychiatry addresses these questions. It involves an attempt to rethink some of the fundamental assumptions of mental health work, showing how recent developments in philosophy and ethics can help us to clarify some of the dilemmas and conflicts around different understandings of madness. Throughout, the authors examine the conflicting ways in which politicians, academics, and mental health professionals appear to understand madness, and contrast this with voices and experiences that are usually excluded - those of the people who use mental health services. They then examine the power of psychiatry to shape how we understand ourselves and our emotions, before considering some of the basic limitations of psychiatry as science to make madness meaningful. In the final section of the book they draw on evidence from service users and survivors, the humanities and anthropology, to point out a new direction for mental health practice. This new direction emphasises the importance of cultural contexts in understanding madness, placing ethics before technology in responding to madness, and minimising 'therapeutic' coercion. (shrink)

This paper analyzes the metaphysical system developed in Cheyne’s Philosophical Principles of Religion. Cheyne was an early proponent of Newtonianism and tackled several philosophical questions raised by Newton’s work. The most pressing of these concerned the causal origin of gravitational attraction. Cheyne rejected the occasionalist explanations offered by several of his contemporaries in favor of a model on which God delegated special causal powers to bodies. Additionally, he developed an innovative approach to divine conservation. This allowed him to argue that (...) Newton’s findings provided evidence for God’s existence and providence without the need for continuous divine intervention in the universe. (shrink)

Gerrit Lindeboom’s biography, Herman Boerhaave: The Man and His Work, presents a heroic account of Herman Boerhaave’s life and his many contributions to medicine and medical education. He is portrayed as an outstanding eighteenth century educator who introduced into Leiden’s Medical School a novel method of clinical teaching that was to be widely adopted and today remains at the centre of medical student instruction. Lindeboom’s historiography induced a resurgence of interest in Boerhaave, a renewal of the myth concerning Boerhaave’s innovative (...) teaching and the publication of many acclamatory articles and false epithets, and several critical analyses. Such varying responses prompted this critical examination of the extant Boerhaavian literature, an appraisal of Lindeboom’s objectivity and an assessment of his representations of Boerhaave’s clinical teaching. In doing so, the moral nature of his historiography and that of those who were to sustain his assertions will be established, and the myth that surrounds the novelty and excellence of Boerhaave’s clinical teaching will be evident.

This book offers a comprehensive overview of the arguments relating to the extent and manner to which social influences enable epistemic agents.

On the 4th of December 1967, Hans Kamp sent his UCLA seminar notes on the logic of ‘now’ to Arthur N. Prior. Kamp’s two-dimensional analysis stimulated Prior to an intense burst of creativity in which he sought to integrate Kamp’s work into tense logic using a one-dimensional approach. Prior’s search led him through the work of Castañeda, and back to his own work on hybrid logic: the first made temporal reference philosophically respectable, the second made it technically feasible in a (...) modal framework. With the aid of hybrid logic, Prior built a bridge from a two-dimensional UT calculus to a one-dimensional tense logic containing the ‘now’ operator J. Drawing on material from the Prior archive, and the paper “‘Now”’ that detailed Prior’s findings, we retell this story. We focus on Prior’s completeness conjecture for the hybrid system and the role played by temporal reference. (shrink)

In this paper we argue that Prior and Reichenbach are best viewed as allies, not antagonists. We do so by combining the central insights of Prior and Reichenbach in the framework of hybrid tense logic. This overcomes a well-known defect of Reichenbach’s tense schema, namely that it gives multiple representations to sentences in the future perfect and the future-in-the-past. It also makes it easy to define an iterative schema for tense that allows for multiple points of reference, a possibility noted (...) by Prior and demanded by Comrie, and we sketch how this schema can be generalized to a shift-and-restrict pattern in which special propositional symbols act as restrictors on the range of tense operators.

From social media to the halls of academia all the way to the White House, everyone is talking about “lived experience”. Yet, there is considerable confusion about what, precisely, the term means. Part of this confusion results from the lack of awareness about the origin of the term and the philosophical need that it was introduced to address. Accordingly, the first aim of this essay is to elucidate the meaning of “lived experience” by teasing out and enumerating its various features (...) as found in the thought of Wilhelm Dilthey, who first developed and popularized it as a philosophical concept. The second goal is to critique the use of “lived experience” in contemporary academic and political discourse. Lived experience is simultaneously denigrated by those who regard it as merely subjective and exalted by those who regard it as epistemically authoritative. A return to Dilthey’s original formulation reveals that both of these attitudes are predicated on misunderstandings of the nature of lived experience. (shrink)

This paper offers a new approach to an old debate about superaddition in Locke. Did Locke claim that some objects have powers that are unrelated to their natures or real essences? The question has split commentators. Some (Wilson, Stuart, Langton) claim the answer is yes and others (Ayers, Downing, Ott) claim the answer is no. This paper argues that both of these positions may be mistaken. I show that Locke embraced a robust epistemic humility. This epistemic humility includes ignorance of (...) the real essences of bodies, of the causal processes underlying the production of natural phenomena, and of God’s method of creation. I show how this epistemic humility offers strong support for an agnostic response to the question of superaddition. Locke did not intend to claim that bodies either do or do not have properties unrelated to their real essences. Instead, his primary goal in discussing the topic was to emphasize the strict limits to human knowledge. (shrink)

This paper explores the metaphysical system developed in Richard Bentley’s 1692 Boyle Lectures. The lectures are notable for their attempt to argue that developments in natural philosophy, including Newton’s Principia, could bolster natural theology. The paper explores Bentley’s matter theory focusing on his commitment to a particular form of mechanism and his rejection of occult qualities. It then examines his views on the nature of divine omnipotence. Finally, it turns to his understanding of gravitational attraction. While some recent commentators have (...) argued for a “superaddition” interpretation of gravitation in Bentley, this paper argues for an “occasionalist” interpretation. The argument proceeds on the basis of both textual considerations and considerations stemming from the systematic interpretation of Bentley’s metaphysics developed earlier in the paper. (shrink)

This essay addresses a stream of thought manifested in some forms of social justice activism – namely, that members of marginalized groups have privileged insight into the nature of social reality which others cannot understand, much less critique. This position, which I call “epistemic isolationism,” seems to rest on the claim that the knowledge that is embedded in lived experience is incommunicable. The essay proceeds in three parts: first, there is a brief overview of standpoint epistemology, including a recent version (...) which seems to support epistemic isolationism. Second, there is an explication of the concept of “lived experience” as developed by Wilhelm Dilthey. Third, there is an argument against the claim that lived experience is incommunicable, drawing from the work of Dilthey, Hans-Georg Gadamer, and Paul Ricoeur. The payoff of the argument is that sharing lived experience through expressions like literature and narrative inspires mutual recognition and respect which can, in turn, support a robust form of solidarity and serve as a foundation for more effective social justice advocacy.

Despite its philosophical interest, Susanna Newcome’s Enquiry Into the Evidence of the Christian Religion (1728, revised 1732) has received little attention from commentators. This paper seeks to redress this oversight by offering a reconstruction of Newcome’s innovative argument for God’s existence. Newcome employs a cosmological argument that differs from Thomist and kalām version of the argument. Specifically, Newcome challenges that idea that the causal chains observed in nature can exist independently. She does this through an appeal to findings from Newtonian (...) natural philosophy that suggest that the universe has entropic tendencies. This suggests that the continued operations of nature are dependent on a cause external to the universe. Newcome identifies this external cause with God. Various strengths and weaknesses of Newcome’s argument are discussed and an attempt is made to situate the argument within her broader epistemic framework and the larger context of Newtonian physico-theology. The paper also explores what is known of Newcome’s biography and intellectual milieu. (shrink)

The central claim of this book is that the dichotomy between economic dependence and economic independence is completely inadequate for describing the political challenges faced by contemporary capitalist welfare states. The simplistic contrast between markets and states as sources of income renders invisible the relations of dependence established in our basic economic institutions such as the family, property, and money. This book is a work of political theory that attacks narrow conceptions of dependence and identifies distinct senses of dependence that (...) might allow political communities to make clearer decisions about the justice of our economic institutions and practices. Inheritance, for example, is as much a form of dependence as support by a welfare state, but these are never compared in debates about economic justice. This book begins the work of comparing forms of economic dependence, and argues that economic dependence is always an issue of both vulnerability and parasitism. It builds bridges between political theory and social science, and is of relevance to those concerned with social and economic justice in and beyond contemporary capitalist welfare states. (shrink)

Locke's account of the idea of power is thought to be seriously problematic. Commentators allege that the idea of power causes problems for Locke's taxonomy of ideas, that it is defined circularly, and that, contrary to Locke's claims, it cannot be acquired in experience. This paper defends Locke's account. Previous commentators have assumed that there is only one idea of power. But close attention to Locke's text, combined with background features of his theory of ideas, supports the drawing of a (...) distinction between four different ideas of power. The paper describes each idea and its role in the Essay. It then argues that this distinction can help Locke to avoid the traditional criticisms. (shrink)

Locke famously claimed that morality was capable of demonstration. But he also refused to provide a system of demonstrative morality. This paper addresses the mismatch between Locke’s stated views and his actual philosophical practice. While Locke’s claims about demonstrative morality have received a lot of attention it is rare to see them discussed in the context of his general theory of demonstration and his specific discussions of particular demonstrations. This paper explores Locke’s general remarks about demonstration as well as his (...) claims about demonstration in natural philosophy, mathematics, and morality. Careful attention to these detailed discussions motivates a reevaluation of Locke’s views on demonstrative knowledge of morality. Specifically, while Locke did believe that some demonstrative moral knowledge might be in-principle available to us he also believed that facts about the difficulty of demonstration meant that this knowledge would in-practice be largely unattainable.

In a recent article Fred Ablondi compares the different approaches to occasionalism put forward by two eighteenth-century Newtonians, Colin Maclaurin and Andrew Baxter. The goal of this short essay is to respond to Ablondi by clarifying some key features of Maclaurin's views on occasionalism and the cause of gravitational attraction. In particular, I explore Maclaurin's matter theory, his views on the explanatory limits of mechanism, and his appeals to the authority of Newton. This leads to a clearer picture of the (...) way in which Maclaurin understood gravitational attraction and the workings of nature. (shrink)

This article explores a previously neglected manuscript essay in which Thomas White offers an account of the metaphysics underpinning transubstantiation. White’s views are of particular interest because his explanation employs a broadly mechanist framework, rather than the hylomorphism traditionally associated with Roman Catholic discussions of the Eucharist. The manuscript helps to shed light on a number of topics of importance to early modern philosophy including the reception of Descartes’ views, the relationship between theology and natural philosophy, and mechanist accounts of (...) identity and individuation.

In the Queries to the Latin version of the Opticks Newton claims that space is God’s sensorium. Although these passages are well-known, few commentators have offered interpretations of what Newton might have meant by these cryptic remarks. As is well known, Leibniz was quick to pounce on these passages as evidence that Newton held untenable or nonsensical views in metaphysics and theology. Subsequent commentators have largely agreed. This paper has two goals. The first is to offer a clear interpretation of (...) Newton’s claim about space and God’s sensorium by situating those claims within Newton’s philosophical thought. The second is to show how my interpretation rescues Newton from Leibniz’s critiques. I show that Newton had a considered position on the sensorium and the role it played in sensation and volition. The primary evidence for this comes from an experiment Newton performed involving after-images; an experiment he recorded in his student notebook and corresponded with Locke about. I also discuss Newton’s views on mind-body causation, divine extension, and divine analogy. My final position is that we should read Newton as claiming that space in the venue in which God exercises his divine will. I also consider the problem of the missing tanquam pointed out by Koyré and Cohen and propose a solution. (shrink)
