Mathematicians, physicists, and philosophers of physics often look to the symmetries of an object for insight into the structure and constitution of the object. My aim in this paper is to explain why this practice is successful. In order to do so, I present a collection of results that are closely related to (and in a sense, generalizations of) Beth’s and Svenonius’ theorems.

Chater & Loewenstein argue that i-frame research has been coopted by private interests opposed to system-level reform, leading to ineffective interventions. They recommend that behavioural scientists refocus on system-level interventions. We suggest that the influence of private interests on research is problematic for wider normative and epistemic reasons. A system-level intervention to shield research from private influence is needed.

This essay disambiguates the relationship between phenomenology and explanation, whereby we uncover a fundamentally new way to understand the function of phenomenology within the sciences. These objectives are accomplished in two stages. First, we propose an original way to interpret Husserl's claim that his phenomenology is non-explanatory. We demonstrate, contra accepted interpretations, that Husserl did not think phenomenology is non-explanatory, because it is descriptive or because it does not deal with causes. Instead, we demonstrate that Husserl concluded that phenomenology is (...) non-explanatory, because it engages in a dialectical process of conceptual clarification. To substantiate this interpretation, we examine how Husserl understood the function of explanation in three different tiers of standard science and how he grasped the role of phenomenology in pure logic. Having properly clarified Husserl's conclusion—that phenomenology is non-explanatory—we then execute our second task, namely to challenge just that idea. We argue that Husserl has—despite his claims to the contrary—de facto and inadvertently described his phenomenology as an explanatory nomological science. Our paper therefore not only clears up a longstanding misinterpretation of Husserl, but opens a new area of debate concerning the status of phenomenology within the scientific nexus. (shrink)

This paper presents a simple pair of first-order theories that are not definitionally (nor Morita) equivalent, yet are mutually conservatively translatable and mutually 'surjectively' translatable. We use these results to clarify the overall geography of standards of equivalence and to show that the structural commitments that theories make behave in a more subtle manner than has been recognized.

The purpose of this paper is to examine in detail a particularly interesting pair of first-order theories. In addition to clarifying the overall geography of notions of equivalence between theories, this simple example yields two surprising conclusions about the relationships that theories might bear to one another. In brief, we see that theories lack both the Cantor-Bernstein and co-Cantor-Bernstein properties.

Husserl’s early picture of explanation in the sciences has never been completely provided. This lack represents an oversight, which we here redress. In contrast to currently accepted interpretations, we demonstrate that Husserl does not adhere to the much maligned deductive-nomological (DN) model of scientific explanation. Instead, via a close reading of early Husserlian texts, we reveal that he presents a unificationist account of scientific explanation. By doing so, we disclose that Husserl’s philosophy of scientific explanation is no mere anachronism. It (...) is, instead, tenable and relevant. We discuss how Husserl and other contemporary thinkers draw theoretical inspiration from the same source—namely, Bernard Bolzano. Husserl’s theory of scientific explanation shares a common language and discusses the same themes as, for example, Phillip Kitcher and Kit Fine. To advance our novel reading, we discuss Husserl’s investigations of grounding, inter-lawful explanation, intra-mathematical explanation, and scientific unification. (shrink)

The translational research community, in general, and the Clinical and Translational Science Awards (CTSA) community, in particular, share the vision of repurposing EHRs for research that will improve the quality of clinical practice. Many members of these communities are also aware that electronic health records (EHRs) suffer limitations of data becoming poorly structured, biased, and unusable out of original context. This creates obstacles to the continuity of care, utility, quality improvement, and translational research. Analogous limitations to sharing objective data in (...) other areas of the natural sciences have been successfully overcome by developing and using common ontologies. This White Paper presents the authors’ rationale for the use of ontologies with computable semantics for the improvement of clinical data quality and EHR usability formulated for researchers with a stake in clinical and translational science and who are advocates for the use of information technology in medicine but at the same time are concerned by current major shortfalls. This White Paper outlines pitfalls, opportunities, and solutions and recommends increased investment in research and development of ontologies with computable semantics for a new generation of EHRs.

Objectives. The purpose of this study was to conduct the first randomized controlled trial (RCT) to evaluate the effectiveness of a second-generation mindfulness-based intervention (SG-MBI) for treating fibromyalgia syndrome (FMS). Compared to first generation mindfulness-based interventions, SG-MBIs are more acknowledging of the spiritual aspect of mindfulness. Design. A RCT employing intent-to-treat analysis. Methods. Adults with FMS received an 8-week SG-MBI known as meditation awareness training (MAT; n = 74) or an active control intervention known as cognitive behaviour theory for groups (...) (n = 74). Assessments were performed at pre-, post-, and 6-month follow-up phases. Results. Meditation awareness training participants demonstrated significant and sustained improvements over control group participants in FMS symptomatology, pain perception, sleep quality, psychological distress, non-attachment (to self, symptoms, and environment), and civic engagement. A mediation analysis found that (1) civic engagement partially mediated treatment effects for all outcome variables, (2) non-attachment partially mediated treatment effects for psychological distress and sleep quality, and (3) non-attachment almost fully mediated treatment effects for FMS symptomatology and pain perception. Average daily time spent in meditation was found to be a significant predictor of changes in all outcome variables. Conclusions. Meditation awareness training may be a suitable treatment for adults with FMS and appears to ameliorate FMS symptomatology and pain perception by reducing attachment to self. (shrink)

There are two general routes that Augustine suggests in De Trinitate, XV, 14-16, 23-25, for a psychological account of the Father's intellectual generation of the Word. Thomas Aquinas and Henry of Ghent, in their own ways, follow the first route; John Duns Scotus follows the second. Aquinas, Henry, and Scotus's psychological accounts entail different theological opinions. For example, Aquinas (but neither Henry nor Scotus) thinks that the Father needs the Word to know the divine essence. If we compare the (...) theological views entailed by their psychologies we find a trajectory from Aquinas, through Henry, and ending with Scotus. This theological trajectory falsifies a judgment that every Augustinian psychology of the divine persons amounts to a pre-Nicene functional Trinitarianism. This study makes clear how one's awareness of the theological views entailed by these psychologies enables one to assess more thoroughly psychological accounts of the identity and distinction of the divine persons.

The theory of collective agency and intentionality is a flourishing field of research, and our understanding of these phenomena has arguably increased greatly in recent years. Extant theories, however, are still ill-equipped to explain certain aspects of collective intentionality. In this article we draw attention to two such underappreciated aspects: the failure of the intentional states of collectives to supervene on the intentional states of their members, and the role of non-human factors in collective agency and intentionality. We propose a (...) theory of collective intentionality which builds on the ‘interpretationist’ tradition in metasemantics and the philosophy of mind as initiated by David Lewis and recently developed further by Robbie Williams. The collective-level analogue of interpretationism turns out to look different in some ways from the individual-level theory, but is well-suited to accommodating phenomena such as hybrid collective intentionality. Complemented with Kit Fine’s theory of variable embodiment, such a theory also provides a diachronic account of intentional collectives. (shrink)

This essay examines the promise of the notion of modus vivendi for realist political theory. I interpret recent theories of modus vivendi as affirming the priority of peace over justice, and explore several ways of making sense of this idea. I proceed to identify two key problems for modus vivendi theory, so conceived. Normatively speaking, it remains unclear how this approach can sustain a realist critique of Rawlsian theorizing about justice while avoiding a Hobbesian endorsement of absolutism. And conceptually, the (...) theory remains wedded to a key feature of social contract theory: political order is conceived as based on agreement. This construes the horizontal tensions among individual or group agents in society as prior to the vertical, authoritative relations between authorities and their subjects. Political authority thereby appears from the start as a solution to societal conflict, rather than a problem in itself. I argue that this way of framing the issue abstracts from political experience. Instead I attempt to rethink the notion of modus vivendi from within the lived experience of political conflict, as oriented not primarily toward peace, but political survival. With this shift of perspective, the idea of modus vivendi shows us, pace Bernard Williams, that the “first political question” is not how to achieve order and stability, but rather: what can I live with?

The aim of this paper is to discuss the “Austro-American” logical empiricism proposed by physicist and philosopher Philipp Frank, particularly his interpretation of Carnap’s Aufbau, which he considered the charter of logical empiricism as a scientific world conception. According to Frank, the Aufbau was to be read as an integration of the ideas of Mach and Poincaré, leading eventually to a pragmatism quite similar to that of the American pragmatist William James. Relying on this peculiar interpretation, Frank intended to (...) bring about a rapprochement between the logical empiricism of the Vienna Circle in exile and American pragmatism. In the course of this project, in the last years of his career, Frank outlined a comprehensive, socially engaged philosophy of science that could serve as a “link between science and philosophy”.

Open theists deny that God knows future contingents. Most open theists justify this denial by adopting the position that there are no future contingent truths to be known. In this paper we examine some of the arguments put forward for this position in two recent articles in this journal, one by Dale Tuggy and one by Alan Rhoda, Gregory Boyd, and Thomas Belt. The arguments concern time, modality, and the semantics of ‘will’ statements. We explain why we find none (...) of these arguments persuasive. This wide road leads only to destruction. (shrink)

Abstract: One of the institutional highlights of the encounter between Austrian “wissen¬schaftliche Philosophie” and French “philosophie scientifique” in the first half of the 20th century was the “First International Congress for Unity of Science” that took place 1935 in Paris. In my contribution I deal with an episode of the philosophical mega-event whose protagonist was the American philosopher and semiotician Charles William Morris. At the Paris congress he presented his programme of a comprehensive, practice-oriented scientific philosophy and, in a (...) more elaborated version he published it two years later in Logical Positivism, Pragmatism and Scientific Empiricism (Morris 1937). Morris aimed at a synthesis of formalism, pragmatism, and traditional empiricism that combined the virtues of these accounts while avoided their shortocmings. The core of approach was a comprehensive theory of the concept of meaning. Through an analysis of the concept of meaning he sought to sort out the existing differences and the options for a possible future rapprochment between logical empiricism and pragmatism. Against the overly narrow logical empiricist understanding of philosophy as the syntax of the language of science Morris argued for a “scientific pragmatism” that comprised four levels: (1) Philosophy as Logic of Science, (2) Philosophy as Clarification of Meaning (Peirce), (3) Philosophy as Empirical Axiology (Dewey), and (4) Philosophy as Empirical Cosmology (Whitehead).

In this paper we critically evaluate an argument put forward by William Lane Craig for the existence of God based on the assumption that if there were no God, there could be no objective morality. Contrary to Craig, we show that there are some necessary moral truths and objective moral reasoning that holds up whether there is a God or not. We go on to argue that religious faith, when taken alone and without reason or evidence, actually risks undermining (...) morality and is an unreliable source of moral truths. We recommend a viewpoint on morality that is based on reason and public consensus, that is compatible with science, and that cuts across the range of religious and non-religious positions. (shrink)

Within the Thomistic moral tradition, the is-ought gap is regularly treated as identical to the fact-value gap, and these two dichotomies are also regularly treated as being identical to Aristotle and Aquinas’s distinction between the practical and speculative intellect. The question whether (and if so, how) practical (‘ought’) knowledge derives from speculative (‘is’) knowledge has driven some of the fiercest disputes among the schools of Thomistic natural lawyers. I intend to show that both of these identifications are wrong and the (...) debate has been misframed. The is-ought gap is not the fact-value gap, nor does the is-ought gap correspond to Aquinas’s distinction between the speculative and practical. This opens the possibility of a resolution--within the Thomistic school--to a debate that has, heretofore, proven particularly resistant of consensus. I close by offering a tentative account of precisely how synderesis gives us our first awareness of moral law from a prior speculative understanding. (shrink)

The late Jerry Cohen struggled to reconcile his egalitarian political principles with his personal style of life. His efforts were inconclusive, but instructive. This comment locates the core of Cohen’s discomfort in an abstract principle that connects what we morally ought to be compelled to do and what we have a duty to do anyway. The connection the principle states is more general and much tighter than Cohen and others, e.g. Thomas Nagel, have seen. Our principles of justice always (...) put our personal integrity to the test, unless those principles are designed not to. But to craft principles with an view to avoiding that test is, as Cohen argued, itself to undermine both justice and our integrity. (shrink)

Williams, Elster and Pears hold that an effort to induce in oneself a belief in the truth of some proposition that one believes to be false can succeed only if one manages, somewhere along the way, to forget that one is engaged in such an effort. Although this view has strong intuitive appeal, it is false, and in this paper it is shown to be false by example.

Are demands for equality motivated by envy? Nietzsche, Freud, Hayek, and Nozick all thought so. Call this the Envy Objection. For egalitarians, the Envy Objection is meant to sting. Many egalitarians have tried to evade the Envy Objection.. But should egalitarians be worried about envy? In this paper, I argue that egalitarians should stop worrying and learn to love envy. I argue that the persistent unwillingness to embrace the Envy Objection is rooted in a common misunderstanding of the nature of (...) the charge, what it reveals, and what can be said in response to it. I develop what Bernard Williams might call a vindicatory genealogy of envy, thereby allowing us to see that envy, rather than undermining egalitarian intuitions, can in fact play a distinct justificatory role (when it is fitting), which undermines the Envy Objection.

This article investigates the original meaning of dependent arising in the Buddha’s teaching, by focussing on the imasmi" sati formula. Modern scholars such as the Rhys Davidses, K.N. Jayatilleke and Paul Williams have interpreted it as a princi- ple of causation, comparable to a scientific conception of causation. I argue instead that this formula implies that the Buddha held that causation is nothing more than the correlation of causes and effects, and that it commits the Buddha to a Humean regularity (...) thesis about causation. I draw a distinction between the Buddhist and scientific concepts of causation, and then summarise an alternative approach made by more recent scholars such as Sue Hamilton, Noa Ronkin and Eviatar Shulman, who present dependent arising in terms of conditionality in the causal structure of subjective experience. I conclude by presenting the argument that the imasmi" sati formula does not express a principle of causation but is rather a formula for the method of discovering and presenting causation as conditionality in experience.

Joseph Hannon has expressed a most surprising objection to Aquinas scholar Prof William E. Carroll in his latest paper “Theological Objections to a Metaphysicalist Interpretation of Creation.” The main claim is that Prof. Carroll misunderstands Aquinas' doctrine of creatio ex nihilo by reducing it to a metaphysical notion, rather than considering it in its full theological sense. In this paper I show Hannon's misinterpretation of Carroll's and Thomas Aquinas' thought, particularly by stressing the dependence that the doctrine of (...) providence through secondary causes has on the doctrine of creatio ex nihilo.

This paper reconsiders Ockham's critique of the species theory of cognition. As Ockham understands this theory, it says that the direct objects of cognition are mental representations, or species. According to many commentators, one of Ockham's main objections to this theory was that, if the direct objects of cognition are species rather than external objects, we will never be able to establish whether or not a given species is a veridical representation of the world. In this paper I argue that (...) this line of interpretation sits uneasily with Ockham's epistemology, and offer a new interpretation of Ockham's critique of species. (shrink)

Discussions concerning whether there is a natural right to health care may occur in various forms, resulting in policy recommendations for how to implement any such right in a given society. But health care policies may be judged by international standards including the UN Universal Declaration of Human Rights. The rights enumerated in the UDHR are grounded in traditions of moral theory, a philosophical analysis of which is necessary in order to adjudicate the value of specific policies designed to enshrine (...) rights such as a right to health care. We begin with an overview of the drafting of the UDHR and highlight the primary influence of natural law theory in validating the rights contained therein. We then provide an explication of natural law theory by reference to the writings of Thomas Aquinas, as well as elucidate the complementary “capabilities approach” of Martha Nussbaum. We conclude that a right to health care ought to be guaranteed by the state. (shrink)

I explore what BernardWilliams means by regarding one’s action ‘purely externally, as one might regard anyone else’s action’, and how it links to regret and agent-regret. I suggest some ways that we might understand the external view: as a failure to recognize what one has done, in terms of Williams’s distinction between intrinsic and extrinsic luck, and as akin to Thomas Nagel’s distinction between an internal and external view. I argue that none of these captures what Williams was getting (...) at because they do not allow one to take a view on one’s action. I offer two alternative accounts. One turns around what we identify with, the other concerns what we care about. Both accounts capture how I might regret, rather than agent-regret, my own action. I demonstrate that these accounts can explain the relationship between an insurance payout and the external view, and they can explain the agent-relativity of agent-regret. (shrink)

The concept of empiricism evokes both a historical tradition and a set of philosophical theses. The theses are usually understood to have been developed by Locke, Berkeley, and Hume. But these figures did not use the term “empiricism,” and they did not see themselves as united by a shared epistemology into one school of thought. My dissertation analyzes the debate that elevated the concept of empiricism (and of an empiricist tradition) to prominence in English-language philosophy. -/- In the 1870s and (...) ’80s a lively debate about psychology emerged. Neo-Kantian idealists criticized the very idea that the mind can be studied scientifically. A group of philosopher-psychologists responded, often in Mind. They were among the first to call themselves “empiricists,” arguing that psychology could provide a scientific basis for philosophical progress. Idealists held that empirical psychology depended on premises developed by Locke, Berkeley, and Hume. These premises were allegedly absurd because they rendered ideas of extension, as well as other ideas crucial to natural science, unreal. Those who wanted to advance psychology towards becoming a legitimate science were forced to engage these philosophical attacks, while at the same time to develop empirical theories that could successfully explain some characteristics of experience. I show how James’s theory of space perception accomplished both tasks. -/- In developing this theory, James found he had to reject the Lockean notion that reality is associated with passively-registered sensations. James also abandoned Berkeley and Hume’s claim that ideas are ultimately derived from atomic sensations. Instead, James presented experimental evidence that sensation is a continuous stream. The mind must actively parse this stream if it is to gain a coherent representation of its environment. I argue that James’s stream-of-thought thesis served as a presupposition of his entire psychology. The thesis showed how the labor of investigating the mind could be divided between philosophers and scientists, and in a manner sensitive to the concerns of both. The stream thesis also provided a scientific basis for a new philosophical empiricism that, I argue, has a hidden legacy in the history of analytic philosophy. (shrink)

An overview of debates in ethical theory within Christian Scholasticism in the decades after Thomas Aquinas.

Although the question of whether, in the thought of Thomas Aquinas, sanctifying grace is “created” or “uncreated” has received considerable attention in the last several decades, many of the questions and arguments proposed by those, such as Karl Rahner, Jerome Ebacher, and A.N. Williams, in favor of grace being uncreated have gone unanswered. Among these ancillary questions and arguments are those concerning the proper subject of grace, the categorial classification of grace, and the reason for the mystery and unconsciousness (...) of grace. These questions appear unrelated, but, as this paper argues, they are each logically connected to each other and to the overall thesis that sanctifying grace is created, not uncreated. This paper aims to make Aquinas’s thesis that grace is created more palatable to objectors by addressing each of these previously unaddressed ancillary questions. (shrink)

From the early eighteenth century onward, primacy for the invention of binary numeration and arithmetic was almost universally credited to the German polymath Gottfried Wilhelm Leibniz (1646–1716). Then, in 1922, Frank Vigor Morley (1899–1980) noted that an unpublished manuscript of the English mathematician, astronomer, and alchemist Thomas Harriot (1560–1621) contained the numbers 1 to 8 in binary. Morley’s only comment was that this foray into binary was “certainly prior to the usual dates given for binary numeration”. Almost thirty years (...) later, John William Shirley (1908–1988) published reproductions of two of Harriot’s undated manuscript pages, which, he claimed, showed that Harriot had invented binary numeration “nearly a century before Leibniz’s time”. But while Shirley correctly asserted that Harriot had invented binary numeration, he made no attempt to explain how or when Harriot had done so. Curiously, few since Shirley’s time have attempted to answer these questions, despite their obvious importance. After all, Harriot was, as far as we know, the first to invent binary. Accordingly, answering the how and when questions about Harriot’s invention of binary is the aim of this short paper. (shrink)

Among medieval Aristotelians, William of Ockham defends a minimalist account of artifacts, assigning to statues and houses and beds a unity that is merely spatial or locational rather than metaphysical. Thus, in contrast to his predecessors, Thomas Aquinas and Duns Scotus, he denies that artifacts become such by means of an advening ‘artificial form’ or ‘form of the whole’ or any change that might tempt us to say that we are dealing with a new thing (res). Rather, he (...) understands artifacts as per accidens composites of parts that differ, but not so much that only divine power could unite them, as in the matter and form of a proper substance. For Ockham, artifacts are essentially rearrangements, via human agency, of already existing things, like the clay shaped by a sculptor into a statue or the stick and bristles and string one might fashion into a broom. Ockham does not think that a new thing is thereby created, although his emphasis on the contribution of human artisans seems to leave questions about the ontological status of their agency open. In any case, there are no such things as natural statues, any more than substances created by human artifice. (shrink)

Moral luck is an important issue in meta- ethics. Its conflict to principle of control make challenges to moral moral assessment, moral judgment and moral responsibility. Bernard Williams is the first philosopher who uses the expression "moral luck" and tries to show that the contradiction between “moral” and “luck” is not so serious. Against Kantian’s idea and also our intuitions Williams doesn’t believe that morality is immune of luck and that unlike other values, is accessible to all people. If moral (...) value is accessible to all, according to his idea, it should be not only immune of luck but also supreme. Giving some examples, Williams by concepts like justification, regret and retrospective, shows that morality hasn’t these characteristics. Dividing moral luck into four types: resultant, circumstantial, constitutive and causal, Thomas Nagel puts Williams' moral luck under the first type and criticizes it. This study seeks to explain Bernard Williams’ viewpoint on moral luck. At first it clears types of moral luck, principle of control and its contradiction with moral luck, then after explaining Williams’ account of moral luck criticizes it. Nagel’s criticisms and others show that although they accept the existence of moral luck and also their account is compatible to williams’ but they deny williams’ success in defending of this phenomenon. Finally, despite of all critiques, it seems that Williams’ failure in defense of moral luck didn’t decrease the importance of this matter, but made some stronger ideas were appeared by Thomas Nagel in this regard.

As Thomas Uebel has recently argued, some early logical positivists saw American pragmatism as a kindred form of scientific philosophy. They associated pragmatism with William James, whom they rightly saw as allied with Ernst Mach. But what apparently blocked sympathetic positivists from pursuing commonalities with American pragmatism was the concern that James advocated some form of psychologism, a view they thought could not do justice to the a priori. This paper argues that positivists were wrong to read James (...) as offering a psychologistic account of the a priori. They had encountered James by reading Pragmatism as translated by the unabashedly psychologistic Wilhelm Jerusalem. But in more technical works, James had actually developed a form of conventionalism that anticipated the so-called “relativized” a priori positivists themselves would independently develop. While positivists arrived at conventionalism largely through reflection on the exact sciences, though, James’s account of the a priori grew from his reflections on the biological evolution of cognition, particularly in the context of his Darwin-inspired critique of Herbert Spencer.

Some of the most forceful objections to William Wollaston's moral theory come from his early critics, namely, Thomas Bott (1688-1754), Francis Hutcheson (1694-1746), and John Clarke of Hull (1687-1734). These objections are little known, while the inferior objections of Hume, Bentham, and later prominent critics are familiar. This fact is regrettable. For instance, it impedes a robust understanding of eighteenth-century British ethics; also, it fosters a questionable view as to why Wollaston's theory, although at first well received, soon (...) faded in esteem among philosophers. This paper gives Wollaston's early critics some of the attention they deserve. It reconstructs some of their objections to Wollaston's philosophy, addresses replies to those objections, and shows that despite some minor flaws, the objections succeed. A fact that becomes clear is that Wollaston's philosophy had suffered devastating criticism years before Hume wrote anything against it. (shrink)

This paper challenges Francis Hutcheson's and John Clarke of Hull's alleged demonstrations that William Wollaston's moral theory is inconsistent. It also present a form of the inconsistency objection that fares better than theirs, namely, that of Thomas Bott (1688-1754). Ultimately, the paper shows that Wollaston's moral standard is not what some have thought it to be; that consequently, his philosophy withstands the best-known efforts to expose it as inconsistent; and further, that one of the least-known British moralists is (...) more important than hitherto thought, in that he uncovers the inconsistency Clarke and Hutcheson try in vain to elicit.

During the 13th century, several logicians in the Latin medieval tradition showed a special interest in the nature of impossibility, and in the different kinds or ‘degrees’ of impossibility that could be distinguished. This discussion resulted in an analysis of the modal concept with a fineness of grain unprecedented in earlier modal accounts. Of the several divisions of the term ‘impossible’ that were offered, one became particularly relevant in connection with the debate on ars obligatoria and positio impossibilis: the distinction (...) between ‘intelligible’ and ‘unintelligible’ impossibilities. In this article, I consider some 13th-century tracts on obligations that provide an account of the relation between impossibility and intelligibility and discuss the inferential principles that are permissible when we reason from an impossible – but intelligible – premise. I also explore the way in which the 13th-century reflection on this topic survives, in a revised form, in some early 14th-century accounts of positio, namely, those of William of Ockham, Roger Swineshead and Thomas Bradwardine.

A short reconstruction of the ethical, political and economic doctrines of Thomas Hodgskin, William Thompson and John Gray.

In this collection of essays, philosopher Paul Russell addresses major figures and central topics of the history of early modern philosophy. Most of these essays are studies on the philosophy of David Hume, one of the great figures in the history of philosophy. One central theme, connecting many of the essays, concerns Hume's fundamental irreligious intentions. Russell argues that a proper appreciation of the significance of Hume's irreligious concerns, which runs through his whole philosophy, serves to discredit the deeply entrenched (...) framework for understanding Hume - and much of early modern philosophy - in terms of the idea of "British Empiricism". In a substantive introduction, Russell outlines how his various insights overlap and connect to each other. -/- The volume is organized thematically into five sections: metaphysics, free will, ethics, religion, and general interpretations of Hume's philosophy. The collection also features a previously unpublished essay on Hume's atheism and an essay on Adam Smith's views on religion and ethics that has not been previously published in English. -/- Recasting Hume and Early Modern Philosophy presents the reader with Russell's substantial and significant set of interconnected observations and insights on the matters and figures of the greatest importance in early modern philosophy. These essays not only provide different and original perspectives on the subject, they also show that the various issues addressed are very relevant to each other, as well as to a number of major topics in contemporary philosophy.

Reprinted in Philosophical and Theological Essays on the Trinity, Oxford, 2009, eds Michael Rea and Thomas McCall. In this essay, I assess a certain version of ’social Trinitarianism’ put forward by J. P. Moreland and William Lane Craig, ’trinity monotheism’. I first show how their response to a familiar anti-Trinitarian argument arguably implies polytheism. I then show how they invoke three tenets central to their trinity monotheism in order to avoid that implication. After displaying these tenets more fully, (...) I argue that Trinitarians would do well to hold Moreland’s and Craig’s trinity monotheism at arms length. (shrink)

This presentation of Aristotle's natural deduction system supplements earlier presentations and gives more historical evidence. Some fine-tunings resulted from conversations with Timothy Smiley, Charles Kahn, Josiah Gould, John Kearns,John Glanvillle, and William Parry.The criticism of Aristotle's theory of propositions found at the end of this 1974 presentation was retracted in Corcoran's 2009 HPL article "Aristotle's demonstrative logic".

This chapter will amount to a detailed exposition and exploration of one of the most prominent arguments against the existence of an unsurpassable world: the argument from addition. Endorsed by a variety of thinkers such as St. Thomas Aquinas, Alvin Plantinga, and William Rowe, the argument from addition uses the possibility of adding good things to a candidate unsurpassable world to argue that every world is surpassable. While widely endorsed, the argument has come under recent criticism. By carefully (...) working through a targeted version of the argument, I set out to establish the following: (i) that a world can always contain more good things; (ii) that a suitably restricted additive aggregation principle allows us to say that adding more good things in a certain way is an improvement, and (iii) that objections to the argument from widespread value incomparability fail.

By reconsidering all the available sources (from Simon du Val’s inquisitorial summons of November 1276 to the Continuatio brabantina, from the Fiore to the X canto of Dante’s Paradiso, from William of Tocco to Peckham’s letters) the article calls into question the thesis – still widely shared – according to which Siger of Brabant died in Italy, and more precisely in Orvieto, at the Papal Court, before November 1284. Above all, from a doctrinal point of view, it shows how (...) it is completely implausible that Peckham could refer to Siger of Brabant when, in his letter to the University of Oxford of November 10, 1284, he mentions two Seculars as the main defenders or ‘inventors’ of the thesis of the uniqueness of the substantial form in the human compound. The end of Siger in Italy could thus be, for the most part, a ‘black legend’, like that of the poisoning of Thomas Aquinas on behalf of Charles of Anjou. The article closes by showing some possible implications, even of a methodological nature, of this different approach. (shrink)

The sense of balance remains a Cinderella among our senses. Although the vestibular apparatus and the apprehension of motion, equilibrium and orientation which it serves has now been studied extensively and descriptions abound in textbooks on perceptual psychology, its key role in our agency remains neglected in philosophical accounts of perception. Popularly received wisdom on the senses also largely ignores balance and it has recently even been called 'the lost sense'. -/- Recognition for the discovery of this sense should probably (...) be accorded to Thomas Reid and his contemporary William Charles Wells. Both made crucial observations before the close of the eighteenth century. Since there is now a tendency to emphasize the role of the agent, brain plasticity, and the development of motor skills in all perceptual tasks, some of Reid's comments in particular strike us as remarkably modern. Reid also differs from many authorities in crediting the sense with specific sensations, as would be expected given the role of sensations in his epistemological scheme. -/- In this paper some of the fascinating facts about the sense of balance are reviewed so that Reid's remarks can be evaluated in a modern context. Similarities and differences in the approaches of Wells and Reid are considered and the value that Reid's insights have even now in understanding perceptual processes is explored. It is suggested that Reid should indeed be counted among the hitherto unacknowledged discoverers of this fundamental sense. (shrink)

These reflections are an attempt to get to the heart of the "reason is the slave of the passions" debate. The whole point of deliberation is to arrive at a choice. What factors persons find to be choice-relevant is a purely empirical matter. This has significant consequences for the views of Hume, Williams, Nagel, Parfit and Korsgaard regarding practical reason.

This paper offers an analysis of a hitherto neglected text on insoluble propositions dating from the late XiVth century and puts it into perspective within the context of the contemporary debate concerning semantic paradoxes. The author of the text is the italian logician Peter of Mantua (d. 1399/1400). The treatise is relevant both from a theoretical and from a historical standpoint. By appealing to a distinction between two senses in which propositions are said to be true, it offers an unusual (...) solution to the paradox, but in a traditional spirit that contrasts a number of trends prevailing in the XiVth century. It also counts as a remarkable piece of evidence for the reconstruction of the reception of English logic in italy, as it is inspired by the views of John Wyclif. Three approaches addressing the Liar paradox (Albert of Saxony, William Heytesbury and a version of strong restrictionism) are first criticised by Peter of Mantua, before he presents his own alternative solution. The latter seems to have a prima facie intuitive justification, but is in fact acceptable only on a very restricted understanding, since its generalisation is subject to the so-called revenge problem.

As noted in 1962 by Timothy Smiley, if Aristotle’s logic is faithfully translated into modern symbolic logic, the fit is exact. If categorical sentences are translated into many-sorted logic MSL according to Smiley’s method or the two other methods presented here, an argument with arbitrarily many premises is valid according to Aristotle’s system if and only if its translation is valid according to modern standard many-sorted logic. As William Parry observed in 1973, this result can be proved using (...) my 1972 proof of the completeness of Aristotle’s syllogistic. (shrink)

Before you think of buying it read some reviews on Amazon and read reviews of its competition: For example, my review of the 2008 Oxford Companion to Philosophy, History and Philosophy of Logic,29:3,291-292. URL: http://dx.doi.org/10.1080/01445340701300429 -/- Some of the entries have already been found to be flawed. For example, Tarski’s expression ‘materially adequate’ was misinterpreted in at least one article and it was misused in another where ‘materially correct’ should have been used. The discussion provides an opportunity to bring more flaws to light. -/- Acknowledgements: Each of these entries was presented at meetings of The Buffalo Logic Dictionary Project sponsored by The Buffalo Logic Colloquium. The members of the colloquium read drafts before the meetings and were generous with corrections, objections, and suggestions. Usually one 90-minute meeting was devoted to one entry although in some cases, for example, “axiomatic method”, took more than one meeting. Moreover, about half of the entries are rewrites of similarly named entries in the 1995 first edition. Besides the help received from people in Buffalo, help from elsewhere was received by email.

En 1969 Harry Frankfurt publica su seminal artículo “Alternate Possibilities and Moral Responsibility”. Allí ataca la necesidad del principio de posibilidades alternativas (PPA) para la adscripción de responsabilidad moral a los agentes cuando estos realizan una acción. Desde entonces, muchos han sido los intentos de defender el PPA y de mostrar su necesidad para la adscripción de la responsabilidad moral. En este ensayo se examina uno de esos intentos: el que se basa en la causalidad-agencial propuesta por Thomas Reid (...) (1710-1796), y que cuenta con William Rowe como uno de sus defensores dentro de la discusión contemporánea. Esto, con el objetivo de mostrar que, si bien esta defensa podría permitir la aparición de lo que se conoce como un “parpadeo” de libertad, ello no es suficiente para sustentar la atribución de responsabilidad moral.

I discuss Malthus, Thomas Robert "The unpublished papers in the collection of Kanto Gakuen University", Pullen, John; Parry, Trevor Hughes (eds). I argue that the theological dimension in Malthus’s overall project may be stressed in the light of some of the original materials published here for the first time. -/- .

In a recent article on Reid’s theory of single and double vision, James Van Cleve considers an argument against direct realism presented by Hume. Hume argues for the mind-dependent nature of the objects of our perception from the phenomenon of double vision. Reid does not address this particular argument, but Van Cleve considers possible answers Reid might have given to Hume. He finds fault with all these answers. Against Van Cleve, I argue that both appearances in double vision could be (...) considered visible figures of the object, and show how this solution might preserve Reid’s direct realism. However, this solution is not compatible with the single appearance of an object predicted by Reid’s theory of single and double vision. This consequence will appear evident once we consider the critique of Reid’s theory of single and double vision formulated by William Charles Wells (1757-1817). Wells argues that Reid’s theory is either incomplete or incompatible with other claims made by Reid. It is incomplete since it fails to specify the unique direction in which we the object in single vision; if it not incomplete and is compatible with the law of monocular direction given by Reid, then it is incompatible with Reid’s claim that we do not perceive immediately distance by sight.

In this paper, we present the results of the construction and validation of a new psychometric tool for measuring beliefs about free will and related concepts: The Free Will Inventory (FWI). In its final form, FWI is a 29-item instrument with two parts. Part 1 consists of three 5-item subscales designed to measure strength of belief in free will, determinism, and dualism. Part 2 consists of a series of fourteen statements designed to further explore the complex network of people’s associated (...) beliefs and attitudes about free will, determinism, choice, the soul, predictability, responsibility, and punishment. Having presented the construction and validation of FWI, we discuss several ways that it could be used in future research, highlight some as yet unanswered questions that are ripe for interdisciplinary investigation, and encourage researchers to join us in our efforts to answer these questions.
