Schizophrenia patients exhibit impairments across multiple clinical, cognitive, and functional domains. A fundamental abnormality of the timing and/or efficiency of neural processes across disparate brain regions (i.e., cortico-cortical communications) may underlie many of the deficits in schizophrenia. Because gamma synchrony is temporally correlated with many cognitive processes, probing patterns of gamma activation may shed light on the functional integrity of neural circuits in schizophrenia and related disorders.

Edward Harold Fulcher Swain (1883?1970) developed a unique idea about the importance of forests, advocating the creation of a new society based upon forests, and he pursued policies to implement his unique vision of forestry when he served as the Director of Queensland's Forestry Board from 1918 to 1924 and the Forestry Commissioner for New South Wales from 1935 to 1948. Swain's beliefs developed out of a combination of his Australian experiences and connections with foresters in the British Empire and (...) America. When he could not convince Australian elites about the need to create a forest-based society, he asked foresters at the 1947 Empire Forestry Conference in London to assert the primacy of forestry in land management in the British Empire. Many foresters positively received parts of Swain's argument, but his ideas could never be fully implemented in the British Empire because of the dominance of agrarian doctrines of development in post-Second World War colonial planning and the rapid process of decolonization. Swain's life sheds light onto current debates among historians about the origin and legacy of forestry in Australia and the British Empire. His ideas, many that parallel the basic tenets of modern environmentalism, require historians to rethink the relationship between Empire forestry and environmentalism. (shrink)

This third volume in a series devoted to luminaries in the history of psychology--features chapter authors who are themselves highly visible and eminent scholars. They provide glimpses of the giants who shaped modern cognitive and behavioral science, and shed new light on their contributions and personalities, often with a touch of humor or whimsy and with fresh personal insights. The animated style, carefully selected details, and lively perspective make the people, ideas, and controversies in the history of psychology come (...) alive. The fields touched on in this and other volumes cover all of the subfields of psychology. As such, all volumes of _Portraits of Pioneers in Psychology_ will be of interest to psychologists, as well as scholars in related fields. The resourceful teacher could use a selection of chapters as supplementary readings to enhance almost any course in the discipline. The major purpose of these books is to provide source materials for students and their teachers in undergraduate and graduate courses in the history of psychology. Each of the five volumes in this series contains different profiles thereby bringing more than 100 of the pioneers in psychology more vividly to life. (shrink)

Recently O’Grady argued that Quine’s “Two Dogmas” misses its mark when Carnap’s use of the analyticity distinction is understood in the light of his deflationism. While in substantial agreement with the stress on Carnap’s deflationism, I argue that O’Grady is not sufficiently sensitive to the difference between using the analyticity distinction to support deflationism, and taking a deflationary attitude towards the distinction itself; the latter being much more controversial. Being sensitive to this difference, and viewing Quine as having reason (...) to insist on a non-arbitrary analyticity distinction, we see that “Two Dogmas” makes direct contact with Carnap’s deflationism. We must look beyond “Two Dogmas” to Quine’s other critiques of analyticity to understand why the arbitrariness of the distinction threatens to undermine or overextend Carnap’s deflationism, collapsing it into a view much like Quine’s. Quine is then seen to achieve many of Carnap’s ends, with the important exception of deflationism. (shrink)

(Updated 5/23/24) This unpublished paper, which readers should feel free to cite, is posted primarily for the historical record. In recent work that has, deservedly, received some attention, Paul R. Daniels presents and defends a non-standard theory of persistence that he dubs transdurantism, according to which persisting objects are temporally extended simples. This is exactly what I do in work dating back to Spring 2004. (This work includes this version of this paper, as well as later version that was presented (...) to the University of Rochester's Philosophy Department in 2005.) While this might be a total coincidence, I doubt that it is, especially given that 'transdurantism' appears as a name for a theory of persistence associated with me in at least two places in the literature, one of which includes a citation of this paper. The paper begins with a discussion of what I call 'locative relations' (the relations borne by material objects to the regions of space and time they occupy), which draws relevant distinctions that others have failed to draw. The results of this discussion are then used in constructing spatial analogues for the three established theories of persistence--endurantism, perdurantism, and exdurantism--as well as for transdurantism. Next, these four views concerning persistence are explicitly formulated and a defense of their formulation is offered. Finally, transdurantism's advantages and disadvantages relative to the other theories are discussed. The main goal of the paper is to challenge the trichotomy between the established theories by arguing that transdurantism is also a viable view concerning persistence through time. [Note: Befitting its status as a historical document, with the exception of some light editing to fix typos that might impede understanding, no changes have been made to the paper.]. (shrink)

ABSTRACT:Although Alasdair MacIntyre has criticized both the market economy and applied ethics, his writing has generated significant discussion within the literature of business ethics and organizational studies. In this article, I extend this conversation by proposing the use of MacIntyre’s account of the virtues to conceive of management as a domain-relative practice that requires and develops practical wisdom. I proceed in four steps. First, I explain MacIntyre’s account of the virtues in light of his definition of a “practice.” Second, (...) I examine his distinction between “practices” and “institutions.” Third, I explain what I mean by a “domain-relative practice” and defend the claim that it is helpful to conceive of management in those terms. Finally, I highlight several features of practical wisdom as a virtue developed in and integral to standards of excellence within management as a domain-relative practice. (shrink)

A number of recent historians claim to have defeated what they call the ‘conflict thesis’, the idea that there exists some inevitable conflict between Darwinism and Christianity. This is often thought to be part of a broader ‘warfare thesis’, which posits an inevitable conflict between science and religion. But, all they have defeated is one, relatively uninteresting form of this thesis. There remain other forms of the conflict theses that remain entirely plausible, even in light of the historical record.

What really makes the concepts of obligation or permission so important for practical philosophy? What if we could find a better concept, one that, despite the simplicity, could show itself as intuitive and rich as possible? Could justifications be used in common language and practice as a sign of ethical judgment and as a strong motive for action? In most scenarios, for example, it really doesn’t matter if a given action is obliged, permitted or forbidden, one may perform the action (...) as long as a justification for doing it is present. In this sense, the notion of justification seems to be more basic and powerful than other concepts used in the philosophical discourse. The existence of formal systems based on the epistemological side of justification, created by Artemov, led us primarily to think that justification could make the formal discourse much more accurate for ethics than the ones using deontological concepts. In the semantical and syntactical aspects, almost all of Artemov’s systems directly proved to be fruitful for ethical purposes. We also developed combinations between the standard deontic logic and logics of justification, resulting in what whe called the Logics of Normative Justification. These systems were able to change the object of the justification formulas and shed some light in ethics as a whole, normative and metaethics. Metaethics were a forgotten subject in formal ethics. We were also able to deal with some known problems in deontic logic, like the famous Ross’s paradox and the expressiveness of prima facie and all-things-considered obligations. (shrink)

There is widespread agreement that medical care offered at the end of a life ought to accord with the preferences of the person whose life it is, at least if the care requested would not be futile. There is considerable evidence, too, that making care more “patient‐centered” in this way would tend to lower the cost of care, for the simple reason that people in those straits often prefer to avoid the most intrusive and therefore most expensive care. So patient‐centered (...) care could be a win‐win of sorts: there could be a collective benefit of lowering costs along with the individual benefit of conforming care better to what the patient wants. But to what degree should the collective benefit be an express goal of health reform, in light of the fact that a given patient might want whatever intrusive, aggressive interventions stand a chance of prolonging life? This question animates several items in this issue of the Report. (shrink)

In this paper, I show that we should understand the direction of fit of beliefs and desires in normative terms. After rehearsing a standard objection to Michael Smith’s analysis of direction of fit, I raise a similar problem for Lloyd Humberstone’s analysis. I go on to offer my own account, according to which the difference between beliefs and desires is determined by the normative relations such states stand in. I argue that beliefs are states which we have reason to change (...) in light of the world, whereas desires are states that give us reason to change the world. After doing this, I show how the view avoids various objections, including two from David Sobel and David Copp. The paper ends by briefly discussing the relevance of the view to the Humean theory of motivation.

The use of contingent valuation methods for estimating the economic value of environmental improvements and damages has increased significantly. However, doubts exist regarding the validity of the usual willingness to pay CV methods. In this article, we examine the CV approach in light of recent findings from behavioral decision research regarding the constructive nature of human preferences. We argue that a principal source of problems with conventional CV methods is that they impose unrealistic cognitive demands upon respondents. We propose (...) a new CV approach, based on the value-structuring capabilities of multiattribute utility theory and decision analysis, and discuss its advantages and disadvantages. (shrink)

Earl Conee and Richard Feldman have recently argued that the evidential support relation should be understood in terms of explanatory coherence: roughly, one's evidence supports a proposition if and only if that proposition is part of the best available explanation of the evidence. Their thesis has been criticized through alleged counterexamples, perhaps the most important of which are cases where a subject has a justified belief about the future. Kevin McCain has defended the thesis against Byerly's counterexample. I argue that (...) McCain's defense is inadequate before pointing toward a more promising solution for explanationism. The Byerly–McCain exchange is important because it casts light on the difficult issues of the standards for justification and the nature of epistemic support. Furthermore, McCain's defense of explanationism about epistemic support represents an important recent development of the burgeoning explanationist program in epistemology and philosophy of science.

Psychophysical scaling models of the form R = f, with R the response and I some intensity of an attribute, all assume that people judge the amounts of an attribute. With simple biases excepted, most also assume that judgments are independent of space, time, and features of the situation other than the one being judged. Many data support these ideas: Magnitude estimations of brightness increase with luminance. Nevertheless, I argue that the general model is wrong. The stabilized retinal image literature (...) shows that nothing is seen if light does not change over time. The classification literature shows that dimensions often combine to produce emergent properties that cannot be described by the elements in the stimulus. These and other effects cannot be adjusted for by simply adding variables to the general model because some factors do not combine linearly. The proposed alternative is that people initially judge the entire stimulus – the object in terms of its environment. This agrees with the constancy literature that shows that objects and their attributes are identified through their relations to other aspects of the scene. That the environment determines judgments is masked in scaling studies where the standard procedure is to hold context constant. In a typical brightness study the essential stimulus might be the intensity of the light or a difference between the light and the background. The two are perfectly confounded. This issue is examined in the case of audition. Judgments of the loudness of a tone depend on how much that tone differs from the previous tone in both pitch and loudness. To judge loudness people first seem to process the stimulus object in terms of differences between it and other aspects in the situation; only then do they assess the feature of interest. Psychophysical judgments will therefore be better interpreted by theories of attention that are based in biology or psychology than those that are based in classical physics. (shrink)

Frege's Grundgesetze der Arithmetik offers a conception of cpLogic as the study of functions. Among functions are included those that are concepts, i.e. characteristic functions whose values are the logical objects that are the True/the False. What, in Frege's view, are the objects the True/the False? Frege's stroke functions are themselves concepts. His stipulation introducing his negation stroke mentions that it yields [...]. But curiously no accommodating axiom is given, and there is no such theorem. Why is it that some (...) of Frege's informal stipulations never made appearances as axioms? I offer an explanation that sheds new light on the Grundgesetze. No axioms should over-determination the True as a logical object. Perhaps the True = 0, as would be common in the mathematics of characteristic functions. But the logical objects that are cardinal numbers are value ranges correlated with second-level numerical concepts by a non-homogeneous second-level value-range function [...]. The existence of concepts would be ontologically circular if the True is itself a number. We find this circularity perfectly agreeable to Frege, and suggest that he had accepted that the existence of functions that are concepts in his cpLogic may well be ontologically inseparable from the existence of his value-range function. His cpLogic itself stands or falls with the viability of some value-range function. (shrink)

In a number of texts throughout his career, Thomas Aquinas identifies different senses of the term ‘esse’. Most notably, he notes that according to one sense, the term signifies the act of existence (actus essendi), which he famously holds is really distinct from essence in all beings other than God. Perhaps surprisingly, he also notes on a number of occasions that according to another sense, the term ‘esse’ can signify that very principle that he says is distinct from the act (...) of existence, namely, essence. In light of Aquinas's semantic theory, this paper investigates how he coherently holds within his metaphysical system that this term ‘esse’ can signify in different ways both essence and the act of existence. More broadly, what it shows is how, for Aquinas, the metaphysician can look to the modes of signification (modi significandi) of terms and as well as their modes of predication (modi praedicandi) to draw careful conclusions about the modes of existence (modi essendi) of real beings. These considerations reveal that in Aquinas's view, although the grammarian and logician in their way are also concerned with these semantic modes, it is not their job to employ them to discern the various senses of the term ‘being’ or the fundamental modes of being. In the end, this is a task for the metaphysician. (shrink)

The Philosophy of Forgiveness, Volume IV: Christian Perspectives on Forgiveness is a collection of essays that explores different Christian views on forgiveness. Each essay takes up a different topic, such as the nature of divine forgiveness, the basis for forgiving our enemies, and the limits of forgiveness. In some chapters, the views of different philosophers and theologians are explored, figures such as St. John Climacus, Bonaventure, and Nietzsche. In other chapters, the concept of forgiveness is analyzed in light of (...) historical events, such as the Nickel Mines shooting, the Charleston shooting, and the Armenian genocide. The contributors to the volume come from different backgrounds, including philosophy, theology, and psychology. The essays are written for scholars in the humanities, social sciences, and theology, as well as graduate students and upper-division undergraduate students. (shrink)

Denunciations, disclosures and reporting: why do whistleblowing procedures create an ethical dilemma in French corporations? Since July 2006, the requirement that foreign multinationals listed on the New York Stock Exchange (NYSE) implement this practice has been met with stiff resistance in many French companies. French labor unions see this controversy as a clash between the French and Anglo-Saxon models of transparency. To understand the moral reticence of French companies towards whistleblowing, we investigate five distinct perspectives: legal, economic, historical, philosophical and (...) sociological. 1/ We first probe into the legal contradictions in French regulations and find in these paradoxes the symptoms of a national taboo. 2/We report on an economic survey, that gathers empirical data from 82 large French corporations, and analyzes different business sectors in France and the working population covered by a whistleblowing procedure. 3/ To elicit the etiology of this taboo, we return to the historical sources of the Dreyfus Affair and the Vichy regime, whose political traumas remain imprinted on the collective French memory. The linguistic confusion between the two French terms délation and dénonciation shows why whistleblowing is perceived in France more as an act of betrayal than of heroism. 4/ The philosophical roots of whistleblowing also shed light on the organizational behavior of French companies and the transparency they are struggling to promote. 5/Entangled in sociological ambiguities, we discuss why French companies see whistleblowing as a risk, not as a means to prevent risk.

Theology and philosophy have traditionally assumed a radical split between human beings and the rest of creation. Philosophically, the split is usually justified in terms of a locus humanus, some one cognitive trait that human beings possess and nonhuman animals do not. Theologically, this trait is usually identified as that which makes us in the image of God. Research in animal cognition, however, suggests that we are not unique in as many respects as we think we are. This suggests that (...) we rethink the idea of the image of God. In light of this, I propose that we think of nature itself as being in the image of God, with humankind as part of the broader natural and theological process. (shrink)

Many discussions of J. S. Mill's concept of liberty focus too narrowly on On Liberty and fail to acknowledge that his treatment of related issues elsewhere may modify its leading doctrines. Mill and Paternalism demonstrates how a contextual reading suggests that in Principles of Political Economy, and also his writings on Ireland, India and on domestic issues like land reform, Mill proposed a substantially more interventionist account of the state than On Liberty seems to imply. This helps to explain Mill's (...) sympathies for socialism after 1848, as well as his Malthusianism and feminism, which, in conjunction with Harriet Taylor's views, are central to his later discussions of the family and marriage. Feminism, indeed, is shown to provide the answer to the problem which most agitated Mill, overpopulation. Thus Gregory Claeys sheds new lights on many of Mill's overarching preoccupations, including the theory of liberty at the heart of On Liberty. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Scholars of Bonaventure's thought labor under the difficulty that the Seraphic Doctor is more widely admired than read. Yet there is one advantage they may claim: the immense popularity down through the centuries of his magnum opus: the Itinerarium mentis in Deum, "The Journey of the Mind to God." The text is poetic, concise, and dense. It summarizes many points in Bonaventure's philosophy, theology, and spirituality – indeed, it (...) has sometimes been called a summa of his spiritual theology.In the present essay, I offer a proposal for reading the Itinerarium. I do so with two types of readers in mind. One is the Bonaventure scholar, for whom I make certain arguments concerning the logic of the text and its relationship to other works of Bonaventure. The other is the non-specialist who wishes to teach the Itinerarium as a significant part of the Christian theological patrimony. To the latter, I offer a schematic to understand the different elements of the text in their relationship to each other. This guided reading will, I hope, help the teacher to present the scientific power of Bonaventure's theology.I. Preliminary NoteMy preliminary claim is that the Itinerarium is best understood as divided into two trajectories: one involves the three stages of seeing God through the visible world, the soul, and what is above the soul; the other involves the three stages of seeing God in the visible world, the soul, and what is above the soul. This claim might be criticized by readers of the text. Bonaventure gives several possibilities for understanding the structure of the text in the first part of chapter 1, and does not state that one should be privileged above the others. However, as he goes on to explain each stage, the division that keeps reappearing is that of seeing God through and in the visible world, the soul, and what is above the soul. I therefore regard that division as the most significant. In what follows, I first examine certain antecedents to the Itinerarium's structural argument in earlier works of Bonaventure. I then outline the first trajectory, highlighting its similarities and differences with those earlier works, and then the second trajectory, highlighting its uniqueness and proposing a key by which it may be understood. I close with a brief statement of the significance of my reading in light of some recent scholarship.For reference, one may use the following chart, delineating the trajectories.Knowing God through Knowing God inwhat is below the soul chap. 1: the consideration of God through his vestiges in the universe chap. 2: the consideration of God in his vestiges in this visible worldthe soul chap. 3: the consideration of God through his image imprinted on our natural powers chap. 4: the consideration of God in his image reformed through the gifts of gracewhat is above the soul chap. 5: the consideration of the divine unity through its primary name which is Being chap. 6: the consideration of the most blessed Trinity in its name which is the GoodII. Antecedents to This Kind of Consideration of GodA) Knowing God through and inThe distinction between seeing God through and in is not unique to the Itinerarium. It occurs earlier, in the Commentary on the Sentences, in two places. Though the contexts and the language are slightly different, the content of the distinction is the same. To know God through creatures is "to be raised from the knowledge of the creature to the knowledge of God as by way of a intermediate ladder." To know God in creatures is rather to know "his presence and influence in the creature." Bonaventure says further that knowing God through creatures is characteristic of wayfarers, and is a knowledge that is.. (shrink)

This paper will deal with three questions regarding Carnap's transition from the position he held at the time of writing Syntax to the doctrines he held during his semantic phase: (1) What was Carnap's attitude towards truth at the time of writing Syntax? (2) What was Carnap's position regarding questions of reference and ontology at the time of writing Syntax? (3) Was Carnap's acceptance of Tarski's analysis of truth and reference detrimental to his philosophical project? Section 1 of this paper (...) will deal with the first of these questions. Special attention will be paid to identifying what it was that prevented Carnap from defining a truth predicate for descriptive languages in Syntax. Section 2 of this paper will deal with the question of Carnap's attitude towards reference and ontology in Syntax. It will be shown that the attempt in Syntax to address ontological questions is seriously defective. Section 3 of this paper addresses the last of the questions posed above. It is argued that in the light of what is established in Sections 1 and 2, Carnap could not have retained the position of Syntax with respect to truth and reference. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:RUSSELL TO FREGE, 24 MAY 1903: "I BELIEVE I HAVE DISCOVERED THAT CLASSES ARE ENTIRELY SUPERFLUOUS" GREGORY LANDINI Philosophy / University of Iowa Iowa City, IA 52242, USA It was his consideration of Cantor's proof that there is no greatest cardinal, Russell recalls in My Philosophical Development, that led in the spring of 1901 to the discovery of the paradox of the class of all classes not members (...) of themselves. "Never glad confident morning again", were Whitehead's reported words (MPD, p. 58). Whitehead was, of course, wrong. Russell had many new confident mornings. One in particular apparently occurred on 19 May 1903. On 23 May Russell wrote in his journal: "Four days ago 1 solved the Contradiction -the relief of this is unspeakable" (Papm 12: 24). The "solution" was communicated to Whitehead, who responded by telegram: "Heartiest congratulations Aristoteles secundus. 1 am delighted" (Clark, p. III). But it was not long before Russell knew his proposal was inadequate. On the form he would scrawl: "A propos of solVing the Contradiction. [But the solution was wrong]" (ibid; Russell's brackets). The episode is intriguing. What was the proposal? Russell's correspondence with Frege sheds some light. On 20 October 1902 Frege had sent a letter suggesting a way to avoid the contradiction. Frege's suggestion, formulated in a great hurry so that it might appear in the Appendix of Vol. II of the Grundgesetze der Arithmetik, was to abandon his Basic Law V; zcj>z =zez. ==. (x)(x. ==. ex), and to replace it by Russell to Frege, 24 May I903 161 V' zz =zez. ==. (x)(x *zz & x* zez: ~ : x. ==. ex). The underlying idea was to accept that one concept may have the same extension as another even though the two concepts are not coextensive. Though he thought the underlying idea "probably correct",! Russell expressed reservation in a reply of 12 December:... I find it difficult to accept your solution even though it is probably correct. Do you deny, e.g., that all classes form a class? And if this is admitted, then it is possible that - ana. Moreover, the class of non-humans is a. non-human. Otherwise it must be admitted that not ail objects fall either under a or not-a; namely, if a is a range of values, then a fails neither under a nor under not-a. This contradicts the law of excluded middle, which will be inconvenient to say the least.2 (Frege I980, p. 151) Frege's response of 28 December does not mention the contradiction, and Volume II of his Grundgesetze appeared early in 1903. Russell's reservations concerning Frege's solution· continue in a letter to Frege of 20 February 1903: What you say about my contradiction is of the greatest interest to me. Do you believe that the range of values remains unchanged if some subclass of the class is assigned to it as a new member? Extension seems to fit this view better than intension. Bur I fe;el far from clear about this question. (Frege I980, p. 155) Frege replied on 21 May, explaining that in general a class does not remain unchanged when a particular subclass is added to it, but that two concepts may have the same extension (the same class) when the only difference between them is that this class falls under the first concept but not under the second (p. 157). Then on 24 May 1903 Russell excitedly wrote Frege of a solution of the paradox of classes: "I received your letter this morning, and 1 am replying to it at once, for russell: the Journal of the Berrrand Russdl Archives McMasrer University Library Press n.S.•2 (wincer 1992-93): 160-85 ISSN 0036-01631 • The same evaluation appears in Russell's Appendix to The Principles ofMathematics (p. 522). 2 Frege's '\- a II b" is Peano and Russell's "a E b".

This paper is a restatement of my earlier analysis of this argument (1954), Revised in the light of critical comments by other scholars and of closer study of the text. It includes a critical discussion of an alternative formalization of the argument, First offered by wilfrid sellars (1955) and retained (with modifications) by colin strang (1963), Which eliminates successfully the inconsistency of the premises of the argument but has dubious support from plato's text.

Groups of people are commonly said to be collectively responsible for what has happened. Sometimes the groups claimed to be responsible are vast in size, as when collective responsibility is ascribed to the class of all Americans or the class of all white males. In this book the concept of collective responsibility is analyzed. It is examined not only in the light of what philosophical proponents have said about it, but a genuine attempt is made to make sense of (...) what ordinary people say about responsibility when it is ascribed to groups of people. Accordingly, it is distinguished from related concepts such as shared responsibility and moral taint. Parallels are examined between the actions of an individual and the actions of a group or collective, parallels which seem to make ascriptions of collective responsibility more plausible. Some philosophers oppose collective responsibility and argue for an individualist type of position; in this regard the positions of Lewis and Sverdlik are critically examined. The final chapter contains the author's own position, a position which affirms that collective responsibility is possible but which also preserves some of the central intuitions of the individualist.

Some recent authors have argued that Aquinas deliberately integrated a pacifist outlook into his just war theory. Others, by contrast, have maintained that his rejection of pacifism was unequivocal. The present article attempts to set the historical record straight by an examination of Aquinas's writings on this topic. In addition to Q. 40, A. 1 of Summa theologiae II–II, the text usually cited in this connection, this article considers the biblical commentaries where Aquinas explains how the Gospel “precepts of patience,” (...) especially Matthew 5:39, “Do not resist evil,” should be interpreted in light of the doctrine of just war. The article concludes that Aquinas formulated a two-stage theory whereby pacifism was rejected as a suitable form of agency for the state (respublica), while it was affirmed as the appropriate response to evil for the agency of the church (ecclesia).

This collection of essays examines urban communities and societies in Asia and the West to shed much-needed light on issues that have emerged as the world experiences its new urban turn. An urbanized world should be an improving place, one that is better to live in, one where humans can flourish.

One thing that unites all of these papers is their people-centred approach, because, after all, a city is its people. (shrink)

Given its title, one might expect Ayn Rand's Introduction to Objectivist Epistemology (ITOE) to outline her positions on the issues normally covered in introductory courses and texts on epistemology. In particular, one might expect to find discussions of epistemic justification- i.e., "our right to the beliefs we have" (Dancy 2005, 263). Justification and the nature of knowledge are widely regarded as the essential subject matter of the field, and, as we will see, Rand effectively agrees with this consensus. 1 Yet (...) her monograph says little directly on these subjects. Rather, it is devoted entirely to the presentation of a theory of concepts. My subject in this essay is how a theory of concepts can be an introduction to an epistemology. More specifically, I will show how Rand's theory and the view of consciousness that it embodies relate to some concerns about justification that are familiar from the contemporary, analytic literature on epistemology. Though I will present some exegesis of Rand and some arguments in support of her positions and related theses of my own, this essay is not primarily exegetical or argumentative. My aim is, rather, to sketch the outlines of an epistemology in a way that brings out the relations between a seldom studied theory of concepts and some much debated questions about justification. I hope in doing so to shed light both on the theory and on the questions. I hope this paves the way for others to argue in greater detail for (or against) the theses I sketch here, and to do so in a way that engages more substantially with the analytic literature. In my view, the chief obstacle to work of this kind has been the lack of a big-picture account of the relation between the subject matter of ITOE and the central concern of analytic epistemology. This is the lack that I aim to remove. (shrink)

It breathed and its form faded; a face appeared that was not its own. His lungs had filled with air of barely breathable density. He was dying. He was dying. He was still dying. The red, pale, hard surfaces of that face turned blue. His inert body became a brownish powder of decaying matter and gave birth to two new organisms.After a minute of silence, the other organism developed. It barely had a face. I watched as this new element emerged from the cranial surface. I looked at a pair of teeth. I thought I saw two sets of tongues, perhaps a beak. I also thought I saw eyes, but it was without eyes. [End Page 153]I started to choke. I felt my body give out on me. I tried to voluntarily get up from my bed. I couldn't. I couldn't and I was exactly aware at that moment of where my body was. I looked at the machine right next to the bed that was breathing for me. I tried to lift it, but I couldn't hold it between my arms. It was too wide and too heavy.My body was shaking with cold, but I didn't feel the cold, I felt the exact opposite. The machine was still working, slowly, now it was useless. I kept it on the bed and kept coughing, I was afraid I would die if I kept doing this... Finally, I got up from the bed. I was ready to die. I was about to take my last breath. I felt this great relief at the idea of disappearing to myself, and also of subsisting in this existence in an insensible form. I was still spitting, and I knew that I was going to die. I was sure that if I continued to cough, I would die again.When he tried to breathe again, the first body closed its jaw with its two legs running outside of me, and he turned on his side to feel the waves invading him and the corals embedding themselves in his organs. The second body continued to fill the mouth of the first machine with air. The second machine exhaled on its own. I can hardly say how long it took for both parties to breathe in again in unison. After that, they got their feet back on the floor and closed their mouths with their tongues, just like in the configuration they were in before.In the room, one of the machines opened and closed to breathe with a slow, muffled sound. It was like a metal accordion that unfolded and seemed to take over the atmosphere of the whole room. I knew that my breathing was following the exact same rhythm. It was a very profound experience in which I felt extreme terror and almost strange excitement all over my body, but I kept my thoughts under control. I remained focused by staring at points of light somewhere behind my skull.The pain of being forced to think is an unhappy pain that is exerted from within, but is felt as from without. I am going to take a last breath. I am going to die. Not now, you are not going to die. Just a moment more. The machine continues to breathe and the pipes vibrate with this breath. I am locked in this hospital room. Nothing changes from one day to the next, the same mechanical breathing. I've probably been poisoned, but without the will to do so. We'll get it over with by ourselves and I'll disappear in a few minutes.I can barely speak... (shrink)

Some critics claim that ontological arguments are dialectically ineffective against sceptics, whatever the sceptics’ broader metaphysical commitments. In this paper, I examine and contest arguments for this conclusion. I suggest that such critics overlook important claims about God’s nature (viz. divine simplicity and divine inimitability) typically advanced by proponents of ontological arguments who endorse classical theism. I reformulate two representative ontological arguments in light of this characterization of God, arguing that for philosophers prepared to endorse Meinongianism or modal Platonism, (...) alongside divine simplicity and inimitability, such arguments are not invalid, question-begging, or obviously liable to parody. Accordingly, two species of ontological argument may possess some persuasive force, albeit for a select audience. (shrink)

One way creatures of fiction seem to differ from real things is in their essential properties. While you and I might not have done many of the things we did do, Anna Karenina could not, surely, have been other than a lover of Vronsky. Is that right? Not straightforwardly: while it is true that “Necessarily, someone who was not a lover of Vronsky would not be Anna”, it is also true that “Someone who was necessarily a lover of Vronsky would (...) not be Anna”. I use a framework developed by Stalnaker to explain this, and to shed light on the semantics of fictional names. (shrink)

This article examines the doctrinal status of just war in the contemporary teaching of the Catholic magisterium. Some passages from Pope Francis’s 2020 encyclical Fratelli tutti, On Fraternity and Social Friendship appear to exclude the just war idea from the social doctrine of the Catholic Church. To gauge whether this is so, the article establishes a baseline comparison to the seminal teaching of Thomas Aquinas on peace and just war. Both St. Thomas and Pope Francis proceed from the assumption that (...) “war” designates a sinful violation of peace. They appear to differ, however, on the question whether a positive meaning should be ascribed to the Roman term bellum justum. To understand if this divergence is purely verbal or involves a substantive disagreement, I consider why Pope Francis’s predecessors have (since the mid-twentieth century) abstained from employing the expression “just war” in their official documents. Finally, Pope Francis’s emphatic statement that St. Augustine ‘forged a concept of “just war” that we no longer uphold in our own day’ is interpreted in light of the passage from his Epistle 229 to Darius that Francis references in Fratelli tutti.

In lieu of an abstract, here is a brief excerpt of the content:318 BOOK REVIEWS ture. But when it comes to love, " we should measure the love of different persons according to the different kinds of union." Thomas underscores what Outka calls the " inclusive " conception of universal love. God is to be loved as the supreme good, as the source of all happiness; the neighbor is loved as sharing in the happiness we receive from God. Charity eviscerates (...) neither our natural inclination for happiness nor our natural associations with others. Rather, it " commands each act of other sorts of friendship " in relation to our friendship with God. Charity is inherently prudential and thus an account of " special relations,'' which Werpehowski and others address, is incorporated into the discussion of charity. Of course one might make the same objection against Thomas's appropriation of Aristotle that I have leveled against the appropriation of modern notions. But Aristotle is not so much a secular rival of Christianity as he is a philosopher of human nature. A return to Christian Aristotelianism is suggested by Kierkegaard's dictum that we have forgotten what it means to be Christian because we have forgotten what it means to be human. THOMAS s. HIBBS Boston College Chestnut Hill, MA The Trinity: An Analysis of St. Thomas Aquinas' Expositio of the "De Trinitate" of Boethius. By DOUGLAS C. HALL. Studien und Texte zur Geistesgeschichte des Mittelalters 33. Leiden/New York: Brill, 1992. Pp. vi + 131. $40 (cloth). Aquinas's expositio of the De Trinitate of Boethius is an admirable paradigm of profound analysis and interpretive genius. Adhering closely to a literal reading of the short sexpartite Boethian tractate, but breaking off his analysis (for reasons unknown) just before the end of section two where Boethius begins his ex professo treatment of the Trinity, Aquinas ends up mainly plumbing the depth of Boethius's prefatory remarks about the epistemological status of theology, and thus in six questions (comprising 24 articles) constructs the most extensive treatment in all his works of the nature and method of theology. Little wonder, then, that Leo Elders titles his introduction to the expositio of Aquinas Faith and Science (Rome, 1974) or that Armand Maurer names his two volume translation of it Faith, Reason and Theology and The Division and Methods of the Sciences (Toronto, 198687 ). In Thomas's commentary, only the fourth article of question three treats the doctrine of the Trinity directly, though the four articles of BOOK REVIEWS 319 question four also discuss the cause of plurality, a crucial topic for trinitarian theology. I was mildly surprised, then, that Douglas Hall gives the title The Trinity to what professes to offer a " careful textual analysis and criticism " (112) of the methods and contents of Aquinas's commentary. In this slender book of four chapters, Hall inserts, between a short introduction and a conclusion, a second chapter on all five of Boethius's tractates and a third on Aquinas's commentary on the De Trinitate. He has some interesting things to say about the dating and contents of the Boethian works, and also makes some good points about Thomas's commentary, especially as regards questions five and six. But the title is a misnomer, for Hall skips over lightly the five articles mentioned above where Aquinas treats trinitarian issues, devoting only three pages to them. Hall's main concern, like Aquinas's, is theological methodology and epistemology. Hall attempts a rather Hegelian, dialectical appraisal of Aquinaswhich stresses Aquinas's reconstruction of Boethius by highlighting their common methodological theme of agnosia-and links it with an integrative approach which grounds itself in " a transcendental reading of Aquinas, while retaining themes from participationist and analogical literature" (112). The first chapter discusses the participationist, analogical, and transcendental strains of contemporary Thomism, and evinces a certain predilection for Rahner (his influence is also evident on pages 50, 58, 92-95). In sum, Hall combines a Rahnerian and dialectical reading of Aquinas. Due to his presupposition, however, he frequently does not engage Aquinas on his own grounds but burdens him with false problems and dubious theses as he seeks to sort out Aquinas's " dialectical tensions." Often the result is a rather gratuitous reading encumbered with unsubstantiated non sequiturs that... (shrink)

Discussions of risk taking in the modern business organization frequently focus upon the behavior of individual moral agents. Here I attempt to identify some of the complexities of risk taking when it is a group phenomenon and to do so in such a way as to shed some light upon the ethics of group risk taking in business organizations.

In lieu of an abstract, here is a brief excerpt of the content:Gregory Currie TEXT WITHOUT CONTEXT: SOME ERRORS OF STANLEY FISH "Intuition told him that the vast ineptitude of the venture would serve as proof that no fraud was afoot." —Jorge Luis Borges, "Tom Castro, the Implausible Imposter," in A Universal History ofInfamy There are those of us who seek unity, universality, patterns of invariance in any diverse multitude of particulars. With the interpretation of texts, the diversity is (...) evident, the unity, universality and invariance less so. Still, we have the text itself, a sequence of determinately meaningful signs, independent of, and a constraint on, the activities of interpreters. We universalists might want more than that, but it's a start. It's a start some people are not prepared to give us. Stanley Fish is one of them. According to him we are looking for something which does not exist, and which we do not need. I shall argue that Fish is wrong on both counts. According to Stanley Fish, there are no constraints on interpretation that transcend particular, local interpretive communities. Indeed, there is no truth or validity that is community transcendent, no standard of lightness, proof or confirmation that has any warrant other than community approval. Intellectual ascendency is always ultimately a matter of rhetorical power, and the locus of power shifts as the norms of the community change. Yet we need not worry that this implies any dangerous kind ofrelativism or subjectivism. Each ofus is deeply immersed Philosophy and Literature, © 1991, 15: 212-228 Gregory Currie213 in his or her own community. Our thoughts, intentions, and actions gain their very identity from the structure of public, communitarian relations we enter into, and the community imposes on us a tight structure of norms and intellectual options that "situate" us (a favored word in the Fish vocabulary) in such a way that it is always clear what interpretive move is appropriate.1 Fish is no epistemological anarchist in the style of Feyerabend: it is not the case, for him, that "anything goes." There is always a clear distinction between what goes and what does not; it is just that the rules, the structure, the hierarchy of options are not invariant across time or communities.2 Now we do it like this, tomorrow we may do it like that; we do it this way, they do it that way. Wherever you are, the rules are always clear, but the rules depend on where you are. I shall call this thesis "internalism." It bears some resemblance to views of the later Wittgenstein, and rather closely parallels Thomas Kuhn's theory of scientific paradigms. It has a negative and a positive aspect. The negative aspect is that community-specific constraints on interpretation are all we have. The positive aspect is that they are all we need. Is internalism correct? I say it is not. I say that the positive claim is false, because internal constraints alone can never answer the relativist's challenge, when that challenge is properly understood; more about that in a moment. But this merely serves to highlight the importance of the negative thesis: if that is correct then relativism carries the day. So my primary concern here is with the negative thesis. Fish's main argument for the negative thesis is that what seems to most of us to be an obvious external constraint on interpretation—the literal meaning of the text in question—is no such thing. And he bases this claim on some arguments which purport to show that there L· no such thing as literal meaning. So my aim, it emerges at last, is to defend the idea of literal meaning. But first, I shall say something about the question of relativism. II Fish's answer to relativism, it will be remembered, is that interpretive communities constrain the interpretive choices of their members in such away that there can always be seen tobe nonarbitrary ways ofproceeding when it comes to formulating and choosing between interpretive hypotheses. This claim, the positive claim of Fish's internalism, raises two questions: Is Fish right, as a matter of fact, about the ways in which interpretive, and more generally intellectual communities constrain the 214Philosophy and Literature thoughts and actions...

What is the role (or roles) of mathematical theory in ecology and evolutionary biology? How does the construction of such theory advance our understanding? The lack of clear answers to this pair of questions has been a source of controversy both within the sciences themselves, and in the philosophical discussions of these sciences as well. In an attempt to shed some light on these issues, I look at what some biologists have had to say on the matter and at (...) some particular examples. I then draw some morals about the constraints on a successful philosophical treatment of the problem and on the limitations of current philosophical approaches to this type of theoretical explanation.

At the fore of concern within Whitehead scholarship are the main interpretive issues revolving around the relationships of God, creativity, and the world. Some critics have charged that Whitehead’s mature thought suffers from a lack of coherence in his formulation of the relationship between God and creativity as they function in cosmic generativity, a charge proven difficult to overcome. Such critics have posed the following question. In light of Whitehead’s commitment to the Ontological Principle, how can God and creativity (...) stand as separate formative elements in the world’s creative advance? This question illustrates, some say, how the separation of God from creativity within Whitehead’s process philosophy.. (shrink)

It has now been more than 50 years since H. L. A Hart and Lord Patrick Devlin first squared off in perhaps the most celebrated jurisprudential debate of the twentieth‐century (1959–1967). The central issue in that dispute—whether the state may criminalize immoral behavior as such—continues to be debated today, but in a vastly changed legal landscape. In this article I take a fresh look at the Hart‐Devlin debate in the light of five decades of social and legal changes.

This volume brings together a number of original articles by leading Leibniz scholars to address the meaning and significance of Leibniz’s notions of compossibility and possible worlds. In order to avoid the conclusion that everything that exists is necessary, or that all possibles are actual, as Spinoza held, Leibniz argued that not all possible substances are compossible, that is, capable of coexisting. In Leibniz’s view, the compossibility relation divides all possible substances into disjoint sets, each of which constitutes a possible (...) world, or a way that God might have created things. For Leibniz, then, it is the compossibility relation that individuates possible worlds; and possible worlds form the objects of God’s choice, from among which he chooses the best for creation. Thus the notions of compossibility and possible worlds are of major significance for Leibniz’s metaphysics, his theodicy, and, ultimately, for his ethics. Given the fact, however, that none of the approaches to understanding Leibniz’s notions of compossibility and possible words suggested to date have gained universal acceptance, the goal of this book is to gather a body of new papers that explore ways of either refining previous interpretations in light of the objections that have been raised against them, or ways of framing new interpretations that will contribute to a fresh understanding of these key notions in Leibniz’s thought.

(Open Access.) Quantifiers frequently figure in works of fiction. But occurrences of quantificational expressions within fictions seem no more inevitably to be associated with real domains than uses of names within fictions seem inevitably to be associated with existing referents. The paper outlines some philosophical puzzles resulting from this apparent lack of associated domains, puzzles that are broadly analogous to more familiar ones raised by the apparently nonreferential nature of many fictional names. The paper argues, in the light of (...) an important disanalogy between quantifiers and names, that the quantificational puzzles are substantive, in that they cannot be resolved merely by appealing to the possibility of empty domains. It then argues that, despite the cited parallels between occurrences of quantifiers and names within fictions, promising treatments of fictional names do not always straightforwardly generalise to provide accounts of the quantificational phenomena: the quantificational puzzles are therefore not only substantive but also distinctive. The paper provides further testament to the depth and interest of the problems involving content that are generated by fiction, by identifying a very wide range of previously neglected cases, while also helping to situate within a broader context the notoriously hard philosophical challenges posed by fictional names.

When a rainbow spans the sky the eye may rest with simple rapture on the arch of colours, or the mind may interpret it as an interplay between raindrops and light. This perceptibly separates the aesthetic relish of the colours from the scientific understanding of the bow. Archbishop Temple distinguished the restfulness of art from the restlessness of science. This applies to the wider aesthetic which includes natural products, such as snow-scenes or daffodils or rainbows, with the pictures, statues, (...) buildings, poems, and other products of man-made art. The rainbow clearly separates the understanding sought by science from the immediate contemplative aesthetic satisfaction with the colours. (shrink)

In his Tractatus, Wittgenstein sets out what he calls his N-operator notation which can be used to calculate whether an expression is a tautology. In his Laws of Form, George Spencer Brown offers what he calls a “primary algebra” for such calculation. Both systems are perplexing. But comparing two blurry images can reduce noise, producing a focus. This paper reveals that Spencer Brown independently rediscovered the quantifier-free part of the N-operator calculus. The comparison sheds a flood light on each (...) and from the letters of correspondence we shall find that Russell, as one might have surmised, was a catalyst for both. (shrink)

Few texts summarize and at the same time compound the challenges of their author's philosophy so sharply as Hermann Cohen's Das Prinzip der Infinitesimalmethode und seine Geschichte . The book's meaning and style are greatly illuminated by placing it in the scientific, political, and academic context of late-nineteenth century Germany. As this context changed, so did both the reception of the philosophy of the infinitesimal and of the Marburg school more generally. A study of this transformation casts significant light (...) on the political relevance of the philosophy of science in theWilhelmine era. As a means of following this development across time, Cohen's text is read through its changing reception in the philosophy of his closest disciple, Ernst Cassirer. (shrink)

This volume shows Russell in transition from a neo-Kantian and neo-Hegelian philosopher to an analytic philosopher of the first rank. During this period his research centred on writing The Principles of Mathematics where he drew together previously unpublished drafts. These shed light on Russell's paradox. This material will alter previous accounts of how he discovered his paradox and the related paradox of the largest cardinal. The volume also includes a previously unpublished draft of an early attempt to solve his (...) paradox, as well as the earliest known version of his generalised relation arithmetic. It contains three articles which have never previously been published in English. (shrink)
