We discuss the principles for a primitive, object-linguistic notion of consequence proposed by ) that yield a version of Curry’s paradox. We propose and study several strategies to weaken these principles and overcome paradox: all these strategies are based on the intuition that the object-linguistic consequence predicate internalizes whichever meta-linguistic notion of consequence we accept in the first place. To these solutions will correspond different conceptions of consequence. In one possible reading of these principles, they give (...) rise to a notion of logical consequence: we study the corresponding theory of validity by showing that it is conservative over a wide range of base theories: this result is achieved via a well-behaved form of local reduction. The theory of logical consequence is based on a restriction of the introduction rule for the consequence predicate. To unrestrictedly maintain this principle, we develop a conception of object-linguistic consequence, which we call grounded consequence, that displays a restriction of the structural rule of reflexivity. This construction is obtained by generalizing Saul Kripke’s inductive theory of truth. Grounded validity will be shown to satisfy several desirable principles for a naïve, self-applicable notion of consequence. (shrink)

The paper considers the philosophical component of the approach to the time as an emergent phenomenon absent at the fundamental level. The anthropic principle is shown as arising from the time emergence. Consciousness is shown as an epiphenomenon in such a model, although it is more fundamental than matter in this case. An answer to the question about the prime cause is suggested.

Some approaches to the assessment of moral intuitions are discussed. The controlled ethical trial isolates a moral issue from confounding factors and thereby clarifies what a person's intuition actually is. Casuistic reasoning from situations, where intuitions are clear, suggests or modifies principles, which can then help to make decisions in situations where intuitions are unclear. When intuitions are defended by a supporting principle, that principle can be tested by finding extreme cases, in which it is counterintuitive to follow (...) the principle. An approach to the resolution of conflict between valid moral principles, specifically the utilitarian and justice principles, is considered. It is argued that even those who justify intuitions by a priori principles are often obliged to modify or support their principles by resort to the consideration of consequences. (shrink)

At first glance, the formulation of the principle of inertia—not. yet complete with Galileo, more precise with Gassendi, finally systematic with Newton—seems to constitute but one of the aspects of a process of deep transformations at the end of which traditional cosmology was replaced by various world systems. These transformations—or, to use a more classic term, this “ scientific revolution” —have been the object of numerous works, a list, of which would alone fill the pages of a thick volume. (...) But the principle of inertia itself, a principle about which can be said without exaggeration that it expressed the essence of this revolution at the same time as it stimulated it, has perhaps not received all the attention it deserves. And especially the impact of this principle on Western culture has not been fully measured. True, Alexandre Koyré has always insisted on the fact that, by reducing movement to a state like that of the state of rest, the principle of inertia expressed a new vision of the world more than a scientific result. But his admirable analyses deal more with the slow advent of the priciple of inertia among the natural philosophers who preceded, accompanied and then followed Galileo than with the theological, philosophical and literary impact of this principle. Moreover, by examining this impact, we discover that it is necessary to make a distinction between Euclidian space and absolute space, a distinction which is frequently implicit with certain scientific historians, but, and this must be emphasized, is more often ignored.

According to Boole it is possible to deduce the principle of contradiction from what he calls the fundamental law of thought and expresses as \. We examine in which framework this makes sense and up to which point it depends on notation. This leads us to make various comments on the history and philosophy of modern logic.

Given intractable secular moral pluralism, the force and significance of the four principles (autonomy, beneficence, non-maleficence, and justice) of Tom Beauchamp and James Childress must be critically re-considered. This essay examines the history of the articulation of these four principles of bioethics, showing why initially there was an illusion of a common morality that led many to hold that the principles could give guidance across cultures. But there is no one sense of the content or the theoretical justification of these (...) principles. In addition, a wide range of secular moral and bioethical choices has been demoralized into lifestyle choices; the force of the secular moral point of view has also been deflated, thus compounding moral pluralism. It is the political generation of the principles that provides a common morality in the sense of an established morality. The principles are best understood as embedded not in a common morality, sensu stricto, but in that morality that is established at law and public policy in a particular polity. Although moral pluralism is substantive and intractable at the level of moral content, in a particular polity a particular morality and a particular bioethics can be established, regarding which health care ethics consultants can be experts. Public morality and bioethics are at their roots a political reality. (shrink)

Philosophers disagree about whether vagueness requires us to admit truth-value gaps, about whether there is a gap between the objects of which a given vague predicate is true and those of which it is false on an appropriately constructed sorites series for the predicate---a series involving small increments of change in a relevant respect between adjacent elements, but a large increment of change in that respect between the endpoints. There appears, however, to be widespread agreement that there is some sense (...) in which vague predicates are gappy which may be expressed neutrally by saying that on any appropriately constructed sorites series for a given vague predicate there will be a gap between the objects of which the predicate is denitely true and those of which it is denitely false. Taking as primitive the operator ‘it is denitely the case that’, abbreviated as ‘D’, we may stipulate that a predicate F is denitely true (or denitely false) of an object just in case ‘DF (a)’, where a is a name for the object, is true (or false) simpliciter.1 This yields the following conditional formulation of a ‘gap principle’: (D Φ (x) ∧ D¬ Φ (y)) → ¬R(x, y). Here ‘ Φ ’ is to be replaced with a vague predicate, while ‘R’ is to stand for a sorites relation for that predicate: a relation that can be used to construct a sorites series for the predicate---such as the relation of being just one millimetre shorter than for the predicate ‘is tall’. Disagreements about the sense in which it is correct to say that vague predicates are gappy can then be recast as disagreements about how to understand the denitely operator. One might give it, for example, a pragmatic construal such as ‘it would not be misleading to assert that’; or an epistemic construal such as ‘it is known that’ or ‘it is knowable that’; or a semantic construal such as ‘it is true that’.

In lieu of an abstract, here is a brief excerpt of the content:The Journal of Aesthetic Education 40.3 (2006) 92-114 [Access article in PDF] A Global Art System: An Exploration of Current Literature on Visual Culture, and a Glimpse at the Universal Promethean Principle—with Unintended Oedipal Consequences Art Education 11-18: Meaning, Purpose And Direction, edited by Richard Hickman; New York, Continuum; 2nd edition, 2004; 176 pp. Global Visual Culture within a Global Art System I have harbored misgivings about the (...) term "visual culture" for several years. Having read Hickman's book with its collection of notable scholars in art and design education, those misgivings turned into qualified acceptance of "visual culture"—so long as it is understood as a global visual culture within a global art system. The ten chapters presented in Hickman's book clearly explore the notion of visual culture in the context of generating an expansive and appropriate canon of art distinctly relevant to our postmodern, multicultural, multidimensional classroom of multiple intelligences.1 And so, art and design education for the twenty-first century must perform three essential functions: one, it must color the classroom with signs of global human pictorial and textual expressions; two, it must attempt to comprehend an immeasurable universe through creative, scaled-down explorations of the phenomenal world all of humanity is subject to; and three, it must open up the Blakeian doors of perception,2 while remaining free of emotional, educational, social, political, or religious ideological bonds. In this light, Hickman's Art Education 11-18 (2004), is a must read for art and design educators currently bogged down in old curriculum, and a must read for educators who incorporate new pedagogical literature easily into their new curriculum. And I say must read because we are on the verge of a revolution in visual art history and education—immersed in it, struggling to make sense of our beloved classical canon of art, and struggling to come to grips with a strangely foreign, beautifully alien, semeiotic reality we call (vaguely) "visual culture." It is a visual culture and history from the north, east, and south. Not just from the west.Key innovative educational issues addressed in these chapters are (respectively) using the dynamic nature of art to expand the curricula (Richard Hickman); the collapse of cultural borders (Lesley Burgess and Nicholas [End Page 92] Addison); a balanced cultural history of the world (Colin Grigg); recognizing art and recognizing visual culture (Howard Hollands); a range of visual cultures and literacy (Darren Newbury); using computer technology as a pathway to a new art and visual culture (Andy Ash); critical study and analysis (Michele Tallack); hand-making as a universal link to nature and art (Rachel Mason); spirituality in the process of art creation (James Hall); and cross-cultural heritage toward a new canon of art (Hickman).I will review each chapter as it pertains to current literature exploring popular pedagogical terms like "visual culture," "postmodernism," "pluralism," and "radicalism" and (more importantly) as it fits into a global system of art and culture. In addition, I suggest another term ("cosmopolitanism"—to identify the viable gay and lesbian aesthetic and culture) not that they are necessarily different, but they are indeed relevant and operate from a fresh literary and historical perspective. Then, I will illustrate how a new, postmodern canon of art must be linked to global visual culture and art in order to expand the concept of visual culture. Thus, I see two tasks before me: the first task is to inventory the philosophy, pedagogy, and meanings within each of the ten chapters in Hickman's Art Education 11-18; and the second task is to integrate key pedagogical ideas highlighted in each chapter as a method of generating a meaningful, holistic, integrated direction for art and design education in the twenty-first century. Integrating Art and Design Education Art is a design process. All subject regimes, D. N. Perkins suggests, are a design process.3 This may seem too obvious now after all these years since the publication of Knowledge... (shrink)

We study the arithmetical schema asserting that every eventually decreasing elementary recursive function has a limit. Some other related principles are also formulated. We establish their relationship with restricted parameter-free induction schemata. We also prove that the same principle, formulated as an inference rule, provides an axiomatization of the Σ2-consequences of IΣ1.Using these results we show that ILM is the logic of Π1-conservativity of any reasonable extension of parameter-free Π1-induction schema. This result, however, cannot be much improved: by adapting (...) a theorem of D. Zambella and G. Mints we show that the logic of Π1-conservativity of primitive recursive arithmetic properly extends ILM.In the third part of the paper we give an ordinal classification of -consequences of the standard fragments of Peano arithmetic in terms of reflection principles. This is interesting in view of the general program of ordinal analysis of theories, which in the most standard cases classifies Π-classes of sentences. (shrink)

When ethics committees evaluate the research proposals submitted to them by biomedical scientists, they can seek guidance from laws and regulations, their own beliefs, values and experiences, and from the theories of philosophers. The starting point of this paper is that philosophers can only be helpful to the members of ethics committees if they take into account in their models both the basic moral intuitions that most of us share and the consequences of people's choices. A moral view which can (...) be labelled as a consequentialist interpretation of mid-level principlism is developed, defended and applied to some real-life and hypothetical research proposals.

The principle of sufficient reason asserts that anything that happens does so for a reason: no definite state of affairs can come into being unless there is a sufficient reason why that particular thing should happen. This principle is usually attributed to Leibniz, although the first recorded Western philosopher to use it was Anaximander of Miletus. The demand that nature be rational, in the sense that it be compatible with the principle of sufficient reason, conflicts with a (...) basic feature of contemporary orthodox physical theory, namely the notion that nature’s response to the probing action of an observer is determined by pure chance, and hence on the basis of absolutely no reason at all. This appeal to pure chance can be deemed to have no rational fundamental place in reason-based Western science. It is argued here, on the basis of other basic principles of quantum physics, that in a world that conforms to the principle of sufficient reason, the usual quantum statistical rules will naturally emerge at the pragmatic level, in cases where the reason behind nature’s choice of response is unknown, but that the usual statistics can become biased when the reason for the choice is empirically identifiable. It is explained here that if the statistical laws of quantum mechanics were to be biased in this way then the basically forward-in-time unfolding of empirical reality described by orthodox quantum mechanics would generate the appearances of backward-time-effects of the kind that have been reported in the scientific literature.

ABSTRACT Clinicians, researchers and the informed public have come to view addiction as a brain disease. However, in nature even extreme events often reflect normal processes, for instance the principles of plate tectonics explain earthquakes as well as the gradual changes in the face of the earth. In the same way, excessive drug use is predicted by general principles of choice. One of the implications of this result is that drugs do not turn addicts into compulsive drug users; they retain (...) the capacity to say ?no?. In support of the logical implications of the choice theory approach to addiction, research reveals that most addicts quit using drugs by about age 30, that most quit without professional help, that the correlates of quitting are the correlates of decision making, and, according to the most recent epidemiological evidence, the probability of quitting remains constant over time and independent of the onset of dependence. This last result implies that, after an initial period of heavy drug use, remission is independent of any further exposure to drugs. In short, there is much empirical support for the claim that addiction emerges as a function of the rules of everyday choice. (shrink)

Any theory of experience which postulates that brain mechanisms generate "raw feel" encounters the impassable "explanatory gap" separating physics from phenomenology.

In this article we argue that the principle of need, on some interpretations, could be used to justify the spending of publically funded health care resources on cognitive enhancement and that this also holds true for individuals whose cognitive capacities are considered normal.The increased, and to an extent, novel demands that the modern technology and information society places on the cognitive capacities of agents, e.g., regarding good and responsible decision-making, have blurred the line between treatment and enhancement. More specifically, (...) it has shifted upwards. As a consequence, principles of need on their most reasonable interpretations can be used to support publically funded cognitive enhancement. At least this is so, if broader aims than curing and ameliorating diseases are included in the goals of health care. We suggest that it would be plausible to see health care as accepting such broader goals already today. (shrink)

Excerpt from Some Principles of Moral Theology: And Their Application The present book is an attempt to bring together, from the Bible and from Christian experience, the principles which have guided the Church in dealing with individual souls; to test those principles by the light of modern knowledge; and to apply them to present-day conditions and needs. Some of the traditional terminology of moral theology has been discarded; much has been retained, either because it seemed the best medium for expressing (...) what had to be expressed, or because it would have been impossible otherwise to indicate the development and formulation of Christian thought on the subject. Thus the book may prove of interest not merely to the clergy and others who are confronted by the practical problems of conduct and morality, but also to students entering upon the study of moral theology for its own sake. The Church of England affords her clergy singularly little expert guidance in this matter of the direction of souls. Two branches of the subject - those which go by the names of Christian ethics and the theory and practice of the confessional respectively - have indeed been systematically and fully treated by recent writers and there is a wealth of practical experience to be drawn both from manuals of pastoral theology and from biographies. Moral theology, however, as will appear, com prises much more than the two topics just mentioned. Yet within the last fifty years, apparently, only three books have attempted to present the whole content of moral theology in such a form as should guide the theory and practice of the Church of England, and all three are out of print and consequently difficult of access.

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in (...) turn, indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.

The principle that a necessarily false proposition implies any proposition, and that a necessarily true proposition is implied by any proposition, was apparently first propounded in twelfth century Latin logic, and came to be widely, though not universally, accepted in the fourteenth century. These principles seem never to have been accepted, or even seriously entertained, by Arabic logicians. In the present study, I explore some thirteenth century Arabic discussions of conditionals with impossible antecedents. The Persian-born scholar Afdal al-Dīn al-Kh (...) najī (d.1248) suggested the novel idea that two contradictory propositions may follow from the same impossible antecedent, and closely related to this point, he suggested that if an antecedent implies a consequent, then it will do so no matter how it is strengthened. These ideas led him, and those who followed him, to reject what has come to be known as 'Aristotle's thesis' that no proposition is implied by its own negation. Even these suggestions were widely resisted. Particularly influential were the counter-arguments of Na īr al-Dīn al-T ī (d.1274). (shrink)

This theoretical paper argues for prioritarianism as an ethical underpinning for digital health in contexts of extreme disadvantage. In support of this claim, the paper develops three prioritarian principles for making ethical decisions for digital health programme design, grounded in the normative position that the greater the need, the stronger the moral claim. The principles are positioned as an alternative view to the prevailing utilitarian approach to digital health, which the paper argues is not sufficient to address the needs of (...) the worst off. As researchers of digital health, we must ensure that the most globally marginalised are not overlooked by overtly technocentric implementation practices. Consequently, the paper concludes by advocating for use of the three principles to support stronger critical reflection on the ethics involved in the design and implementation of digital health programmes.

From the beginning, the implications of quantum theory for our most general understanding of the world have been a matter of intense debate. Einstein argues that the theory had to be regarded as fundamentally incomplete. Its inability, for example, to predict the exact time of decay of a single radioactive atom had to be due to a failure of the theory and not due to a permanent inability on our part or a fundamental indeterminism in nature itself. In 1964, John (...) Bell derived a theorem which showed that any deterministic theory which preserved locality would have certain consequences for measurements performed at a distance from one another. An experimental check seems to show that these consequences are not, in fact, realized. The correlation between the sets of events is much stronger than any local deterministic theory could allow. What is more, this stronger correlation is precisely that which is predicted by quantum theory. The astonishing result is that local deterministic theories of the classical sort seem to be permanently excluded. Not only can the individual decay not be predicted, but no future theory can ever predict it. The contributors in this volume wrestle with this conclusion. Some welcome it; others leave open a return to at lease some kind of deterministic world, one which must however allow something like action-at-a distance. How much lit it? And how can one avoid violating relativity theory, which excludes action-at-a-distance? How can a clash between the two fundamental theories of modern physics, relativity and quantum theory, be avoided? What are the consequences for the traditional philosophic issue of causality explanation and objectivity? One thing is certain; we can never return to the comfortable Newtonian world where everything that happened was, in principle, predictable and where what happened at one measurement site could not affect another set of measurements being performed light-years away, at a distance that a light-signal could not bridge.

_ Source: _Volume 56, Issue 3-4, pp 340 - 366 The history of thinking about consequences in the Middle Ages divides into three periods. During the first of these, from the eleventh to the middle of the twelfth century, and the second, from then until the beginning of the fourteenth century, the notion of natural consequence played a crucial role in logic, metaphysics, and theology. The first part of this paper traces the development of the theory of natural (...) class='Hi'>consequence in Abaelard’s work as the conditional of a connexive logic with an equivalent connexive disjunction and the crisis precipitated by the discovery of inconsistency in this system. The second part considers the accounts of natural consequence given in the thirteenth century as a special case of the standard modal definition of consequence, one for which the principle _ex impossibili quidlibet_ does not hold, in logics in which disjunction is understood extensionally.

Sensitivity is a modal epistemic principle. Modal knowledge accounts are externalist in nature and claim that the knowledge yielding connection between a true belief and the truthmaker must be spelled out in modal terms. The sensitivity condition was introduced by Robert Nozick. He suggests that if S knows that p, then S’s belief that p tracks truth. Nozick argues that this truth-tracking relation can be captured by subjunctive conditionals. As a first approximation, he provides the following modal analysis of (...) knowledge: S knows that p iff (1) p is true; (2) S believes that p; (3) if p were false, S wouldn’t believe that p and (4) if p were true, S would believe that p. The dominant terminology in the literature, also adopted here, is to call condition (3) the sensitivity condition and condition (4) the adherence condition. The sensitivity condition is intuitively appealing since it states that a subject does not know that p if she would believe that p even if p were false. Nozick used the sensitivity condition to accomplish two major tasks. First, he provided a solution to the Gettier problem by arguing that in Gettier cases subjects do not know since the sensitivity condition is violated. Second, he presented a controversial solution to the skeptical problem according to which we have external world knowledge but do not know that the skeptical hypothesis is false. This solution is available because sensitivity is not closed under known entailment. Quickly, criticism of the sensitivity condition emerged. First, most epistemologists regarded the price of abandoning knowledge closure as a price too high to pay. Second, it was noted that sensitivity leads to the counterintuitive consequence of precluding us from inductive knowledge since induction typically yields insensitive beliefs. The most dominant reaction to these problems was to replace sensitivity by the modal principle of safety, nowadays the most popular modal principle. However, sensitivity is not only important as a starting point of modal epistemology. Because of its intuitive attractiveness, many authors aimed at refining the original sensitivity account in order to avoid well-known problems. This has led to a second wave of sensitivity accounts. As of today, various sensitivity-based theories are on the market, including accounts that avoid closure failure, probabilistic interpretations of sensitivity and adherence, and contextualist approaches. There is thus a vivid and ongoing debate about the sensitivity principle in epistemology. (shrink)

Living systems are characterized as self-generating and self-maintaining systems. This type of characterization allows integration of a wide variety of detailed knowledge in biology.The paper clarifies general notions such as processes, systems, and interactions. Basic properties of self-generating systems, i.e. systems which produce their own parts and hence themselves, are discussed and exemplified. This makes possible a clear distinction between living beings and ordinary machines. Stronger conditions are summarized under the concept of self-maintenance as an almost unique character of living (...) systems. Finally, we discuss the far-reaching consequences that the principles of self-generation and self-maintenance have for the organization, structure, function, and evolution of single- and multi-cellular organisms.

One of Etchemendy's arguments against the Tarskian and model‐theoretic notion of logical truth is based on a reduction principle according to which a universally quantified sentence is true if, and only if, all of its instances are logically true. The reduction of logical truth to mere truth reveals that the concept of validity at play in Tarski and in model‐theory relies upon extra‐logical assumptions. A similar reduction had already been put forward by Prawitz, although not with focus on extra‐logical (...) assumptions. Prawitz's reduction concerns rather the possibility of understanding the Tarskian and model‐theoretic approach as implying any epistemic modality. We take into account a possible strategy that an advocate of Tarski and model‐theory may use against Etchemendy's objection, and argue that this strategy fails with respect to Prawitz's criticism. This permits us to shed light upon a difference between Prawitz's and Etchemendy's standpoints: while Etchemendy's reduction shows that the Tarskian and model‐theoretic notion of logical truth cannot be understood as an adequate formal counterpart of truth‐preservation solely by virtue of logical form, Prawitz's reduction insists on the fact that truth‐preservation solely by virtue of logical form is insufficient for epistemic modality to obtain.

What are the limits of the use of artificial intelligence (AI) in the relational aspects of medical and nursing care? There has been a lot of recent work and applications showing the promise and efficiency of AI in clinical medicine, both at the research and treatment levels. Many of the obstacles discussed in the literature are technical in character, regarding how to improve and optimize current practices in clinical medicine and also how to develop better data bases for optimal parameter (...) adjustments and predictive algorithms. This paper argues that there are also in principle obstacles to the application of AI in clinical medicine and care where empathy is important, and that these problems cannot be solved with any of the technical and theoretical approaches that shape the current application of AI in specific areas of clinical medicine in which care for patients is fundamental. This is important, because it generates specific risks that may be overlooked otherwise, and it justifies the necessity of human monitoring and emotional intervention in clinical medicine. Consequently, difficult issues concerning moral and legal responsibility may ensue if these in principle problems are ignored. (shrink)

According to some currents of modern historiography, Galilei's propensity for circular motion would have led him to consider this and not rectilinear motion as “natural motion”; therefore the principle of inertia could not be fully attributed to Galileo, which he would never have formulated. The question of the authorship of the principle of inertia certainly weighs on both nationalistic elements and returns of antigaleleism, while the question of its not explicit formulation as a principle is due to (...) ignorance of the type of organization that Galileo intended to give to the exposition of his physics. The author, after having hinted at possible prodromes of the principle of inertia and having reported the adverse opinions of illustrious historians of science (A. Koyré, I. B. Cohen, P. M. Duhem, P. Rossi, G. Holton), through a careful analysis of the Galilean writings, conducted on the digital versions with the help of text analysis programs, firmly reaffirms Galileo's authorship of the principle of inertia and the consequent principle of classical relativity.

Ethics of social consequences as a form of satisficing non-utilitarian consequentialism can be one of the methodological basis of bioethics education. The primary values in ethics of social consequences are humanity, human dignity and moral rights, which are developed and realized in correlation with positive social consequences. Secondary values in ethics of social consequences include justice, responsibility, moral duty and tolerance. The author analyses human dignity and humanity as principles of bioethics education.

We group the existing variants of the familiar set-theoretical and truth-theoretical paradoxes into two classes: connective paradoxes, which can in principle be ascribed to the presence of a contracting connective of some sort, and structural paradoxes, where at most the faulty use of a structural inference rule can possibly be blamed. We impute the former to an equivocation over the meaning of logical constants, and the latter to an equivocation over the notion of consequence. Both equivocation sources are (...) tightly related, and can be cleared up by adopting a particular substructural logic in place of classical logic. We then argue that our perspective can be justified via an informational semantics of contraction-free substructural logics. (shrink)

Logic, the tradition has it, is normative for reasoning. But is that really so? And if so, in what sense is logic normative for reasoning? As Gilbert Harman has reminded us, devising a logic and devising a theory of reasoning are two separate enterprises. Hence, logic's normative authority cannot reside in the fact that principles of logic just are norms of reasoning. Once we cease to identify the two, we are left with a gap. To bridge the gap one would (...) need to produce what John MacFarlane has appropriately called a bridge principle, i.e. a general principle articulating a substantive and systematic link between logical entailment and norms of reasoning. This is Harman's skeptical challenge. In this paper I argue that Harman's skeptical challenge can be met. I show how candidate bridge principles can be systematically generated and evaluated against a set of well‐motivated desiderata. Moreover, I argue that bridge principles advanced by MacFarlane himself and others, for all their merit, fail to address the problem originally set forth by Harman and so do not meet the skeptical challenge. Finally, I develop a bridge principle that meets Harman's requirements as well as being substantive. (shrink)

According to an appealing and common view, the moral status of an action – whether it is wrong, for example – is sometimes important in itself in terms of the moral status of other actions – especially those that respond to the original action. This view is especially influential with respect to the criminal law. It is accepted not only by legal moralists but also by adherents of the harm principle, for example. In this paper, I argue against this (...) view. The main arguments emphasize the distinctions between the moral status of actions, consequences, and agents. I argue that what matters, in terms of other actions, is not the moral status of the original action but rather other factors that may be confused with it, such as the moral status of its consequences – whether they are good or bad – and the moral status of the agent – whether she is praiseworthy or blameworthy. The intuitive appeal of the common view is, I argue, at least partly due to a conflation of these factors. Most importantly, once we recall the distinctions between these factors, we can see more clearly that this view lacks a compelling rationale. Or, at least, that it is based on assumptions that, first, are much more controversial than their conclusion, and, second, do not support every aspect of this view – and thus do not offer a unified foundation for this view.

We establish the thesis that in moral education, particularly in the first years of the child’s development, unreflexive acts or unreflexiveness in certain behaviours of adults is a condition for the development of the personality structure and virtues that enable autonomous ethical reflection and a relation to the Other. With the notion of unreflexiveness we refer to resolvedness in the response of adults when it is necessary to establish a limit, or cut, in the child’s demand for pleasure, as well (...) as to resolvedness as one of the structurally essential elements in behaviours with which the adult subordinates the child to the symbolic order or language. In philosophy, a symptomatic position in this context is represented by Kant’s theory of education. On the basis of the “traditional” concept of “negative education”, and through Freud’s and Lacan’s psychoanalytic concepts, we identify two principles that should, in contemporary times, be an essential part of the moral educational behaviours of adults: the principle of a delimited response to the child’s demand for the satisfaction of pleasure, and the principle of reasoned, reflected, but nevertheless certain, persevering, resolved unreflexiveness in the subordination of the child’s desire to the symbolic order . On the basis of the preceding analysis, we highlight certain consequences of this structure of the subject for the contexts of particular theoretical discussions and for school practice. (shrink)

We say that a sentence A is a permissive consequence of a set X of premises whenever, if all the premises of X hold up to some standard, then A holds to some weaker standard. In this paper, we focus on a three-valued version of this notion, which we call strict-to-tolerant consequence, and discuss its fruitfulness toward a unified treatment of the paradoxes of vagueness and self-referential truth. For vagueness, st-consequence supports the principle of tolerance; for (...) truth, it supports the requisite of transparency. Permissive consequence is non-transitive, however, but this feature is argued to be an essential component to the understanding of paradoxical reasoning in cases involving vagueness or self-reference.

Guiding principles are central to theory development in physics, especially when there is only limited empirical input available. Here I propose an approach to such principles looking at their heuristic role. I suggest a distinction between two modes of employing scientific principles. Principles of nature make descriptive claims about objects of inquiry, and principles of epistemic action give directives for further research. If a principle is employed as a guiding principle, then its use integrates both modes of employment: (...) guiding principles imply descriptive claims, and they provide directives for further research. By discussing the correspondence principle and the naturalness principle as examples, I explore the consequences for understanding and evaluating current guiding principles in physics. Like principles of nature, guiding principles are evaluated regarding their descriptive implications about the research object. Like principles of epistemic action, guiding principles are evaluated regarding their ability to respond to context-specific needs of the epistemic agent. (shrink)

This paper argues for two principal conclusions about natural language semantics based on John Buridan's considerations concerning the notion of formal consequence, that is, formally valid inference. (1) Natural languages are essentially semantically closed, yet they do not have to be on that account inconsistent. (2) Natural language semantics has to be token based, as a matter of principle. The paper investigates the Buridanian considerations leading to these conclusions, and considers some obviously emerging objections to the Buridanian approach.

I argue that moral principles involve the same sort of generalization as ordinary yet elusive generic generalizations in natural language such as ‘Tigers are striped’ or ‘Peppers are spicy’. A notable advantage of the generic view is that it simultaneously allows for pessimism and optimism about the role and status of moral principles in our lives. It provides a new perspective on the nature of moral principles on which principles are not apt for determining the moral status of particular actions (...) while they may be apt, and even fundamental, to our acquisition of moral knowledge. A natural consequence of the view is variation among moral principles, with some regularly warranting exceptions and some appearing arguably exceptionless. I will also argue that this generic conception of moral principles has significant advantages, as a normative model of moral reasoning, over the view of moral principles as defaults advanced in recent years.
