Modern societies are characterized by a division of epistemic labor between laypeople and epistemic authorities. Authorities are often far more competent than laypeople and can thus, ideally, inform their beliefs. But how should laypeople rationally respond to an authority’s beliefs if they already have beliefs and reasons of their own concerning some subject matter? According to the standard view, the beliefs of epistemic authorities are just further, albeit weighty, pieces of evidence. In contrast, the Preemption View claims that, when one (...) discovers what an authority believes, it is not permissible to rely on any of one’s own reasons concerning the subject matter. The original version of this view, as proposed by Linda Zagzebski, has recently been severely criticized for recommending blind trust and for abandoning even minimal standards for critical thinking. In our paper, we defend a new version of the Preemption View—Defeatist Preemptionism—in a way that differs radically from Zagzebski’s. We argue that our view can be derived from certain widely accepted general epistemic principles. In particular, we claim that preemption can be identified as a special case of source sensitive defeat. Moreover, we argue that Defeatist Preemptionism does not lead to the undesirable consequences that critics ascribe to the Preemption View. The paper thus articulates the foundations and refinements of the Preemption View, such that it adequately captures the phenomenon of epistemic authority and the rational requirements related to it.

We investigated whether motivationally determined stimulus valence can be processed in an automatic way, as is assumed in many appraisal theories (e.g., Frijda, 1986, 1993; Lazarus, 1991; Scherer, 1993a). Whereas appraisal theorists typically use conscious self-report methods to investigate their assumptions, our experiments used indirect experimental methods that leave less room for deliberate, conscious reflections of the participants. Using variants of the affective priming and Simon paradigms, we demonstrated that intrinsically neutral, but wanted stimuli facilitated responses with a positive valence, (...) whereas intrinsically neutral, but unwanted stimuli facilitated negative responses. In addition, the second experiment proved to be supportive of another assumption made by appraisal theorists according to which a relation exits between different (automatic) outcomes of motivational appraisal (positive-negative) and different action tendencies (approach-withdrawal).

The basic bearer of responsibility is individuals, because that isall there are – nothing else can literally be the bearer of fullresponsibility. Claims about group responsibility therefore needanalysis. This would be impossible if all actions must be understoodas ones that could be performed whether or not anyone else exists.Individuals often act by virtue of membership in certain groups;often such membership bears a causal role in our behavior, andsometimes people act deliberately in order to promote the prospectsof members of a given (...) group. Nevertheless, it is rational to awardproportionally to individual contributions to those actions andindividual shares in the production of the consequences of thoseactions. (shrink)

Many views define the concept of automaticity in terms of a number of features, but they differ with regard to the features they put most emphasis on, as well as with regard to the coherence they assume among the features. One contemporary account is the gradual and decompositional view, which proposes to investigate each automaticity feature separately and determine the degree to which it is present. In this chapter, we engage in a detailed analysis of the most important features in (...) order to examine whether they can indeed be regarded as gradual, and whether they can be conceptually and logically separated.

The discovery that people far away are in bad shape seems to generate a sense of guilt on the part of many articulate people in our part of the world, even though they are no worse off now that we’ve heard about them than they had been before. I will take it as given that we are certainly responsible for evils we inflict on others, no matter where, and that we owe those people compensation. Not all similarly agree that it (...) is not in general our duty to make other people better off, and therefore not in general our fault when people are not better off than they happen to be, even if perhaps we could have made them so by efforts of our own. Nev ertheless, I have seen no plausible argument that we owe something, as a matter of general duty, to those to whom we have done nothing wrong. Still, morally commendable motives of humanity and sympathy support beneficence, and if we wish to call those “duties,” there is something to be said for that, too. I shall, in fact, try to say it later in this essay. (shrink)

Of all the attitudes and theories associated with or identified as "pacifism," only the doctrine that everyone ought not to resist violence with force is of philosophical interest, And it is logically incoherent. Pacifism's popularity rests on confusions about what the doctrine really is. If we have rights, We have the right to prevent infringements upon them. We have the right to use force to protect our rights, And in the degree necessary to accomplish that end. (staff).

Is knowledge-how, or “practical” knowledge, a species of knowledge-that, or “theoretical” knowledge? There is no comfortable position to take in the debate around this question. On the one hand, there are counterexamples against the anti-intellectualist thesis that practical knowledge is best analysed as an ability. They show that having an ability to ϕ is not necessary for knowing how to ϕ. On the other hand, the intellectualist analysis of practical knowledge as a subspecies of theoretical knowledge is threatened by its (...) own set of counterexamples, which convincingly establish that practical knowledge lacks many of the typical characteristics of theoretical knowledge. Most strikingly it does not even appear to require a belief. In this paper, I develop an account of practical knowledge that avoids these counterexamples. It also manages to preserve both the status of such knowledge as a cognitive achievement and its apparently close conceptual relation to abilities. I start with the counterexamples against the necessity of abilities for practical knowledge and show that they fail because they underestimate the cognitive demands of attempts. I then make use of the logic of dispositions to bridge the gap that counterexamples against the necessity of abilities for practical knowledge open. It is argued that, instead of the ability to ϕ, it is a specific disposition to have the ability to ϕ that constitutes practical knowledge about ϕ. The resulting theory is an anti-intellectualist position that preserves essential intellectualist motivations and thus should be satisfactory for proponents of both views. (shrink)

As the theory of the atom, quantum mechanics is perhaps the most successful theory in the history of science. It enables physicists, chemists, and technicians to calculate and predict the outcome of a vast number of experiments and to create new and advanced technology based on the insight into the behavior of atomic objects. But it is also a theory that challenges our imagination. It seems to violate some fundamental principles of classical physics, principles that eventually have become a part (...) of western common sense since the rise of the modern worldview in the Renaissance. So the aim of any metaphysical interpretation of quantum mechanics is to account for these violations. (shrink)

The book gives an painstaking analysis of Niels Bohr's understanding of quantum mechanics based on a claim that Bohr was influenced by Harald Høffding's approach to philosophical problems.

This brief paper is a general treatment of war – its morality and its political and social effects. Accordingly, we discuss primarily those armed interactions between nations, or, in “civil” wars, those aimed at securing the reins of government. These must, we contend, be inherently immoral on one side – the one which “starts” the war in question – and inherently moral on the other, who after all are defending their lives against the first. To say this requires a moral (...) theory, which we briefly develop. It proceeds on Hobbesian-contractarian lines: if mankind occupies a “state of nature,” then we will all be worse off than if we join with each other in adopting the restrictions of morality – fundamentally, and primarily, of nonviolence, of living at peace with each other. This raises a question about the very rationality of war, to be sure. And yet, war we have, in considerable and unfortunate abundance. How can this be? Some tentative answers are suggested. (shrink)

This study is part of a programme to elicit and examine community preferences for health care in different contexts. Data were obtained from a group of predominantly Australian health care decision-makers. A short questionnaire contained six valuation questions and four demographic questions. The six valuation questions posed choices where equal health gains were to be allocated to different population groups based upon: age; sex; current health; socio-economic status; across time; and across different numbers of individuals. The results provide some evidence (...) that respondents were prepared to discriminate between health gains derived in different contexts especially where health gains were to be allocated between groups of different health status and over time. Further research is planned and the possible implications for health policy, and in particular for resource allocation in health care, are briefly discussed. (shrink)

The last decade has seen an increasing number of references to quantum mechanics in the humanities and social sciences. This development has in particular been driven by Karen Barad’s agential realism: a theoretical framework that, based on Niels Bohr’s interpretation of quantum mechanics, aims to inform social theorizing. In dealing with notions such as agency, power, and embodiment as well as the relation between the material and the discursive level, the influence of agential realism in fields such as feminist science (...) studies and posthumanism has been profound. However, no one has hitherto paused to assess agential realism’s proclaimed quantum mechanical origin including its relation to the writings of Niels Bohr. This is the task taken up here. We find that many of the implications that agential realism allegedly derives from a Bohrian interpretation of quantum mechanics dissent from Bohr’s own views and are in conflict with those of other interpretations of quantum mechanics. Agential realism is at best consistent with quantum mechanics and consequently, it does not capture what quantum mechanics in any strict sense implies for social science or any other domain of inquiry. Agential realism may be interesting and thought provoking from the perspective of social theorizing, but it is neither sanctioned by quantum mechanics nor by Bohr’s authority. This conclusion not only holds for agential realism in particular, it also serves as a general warning against the other attempts to use quantum mechanics in social theorizing. (shrink)

The concept of an ontological category is central to metaphysics. Metaphysicians argue about which category of existence an object should be assigned to, whether one category can be reduced to another one, or whether there might be different equally adequate systems of categorization. Answers to these questions presuppose a clear understanding of what precisely an ontological category is, and Jan Westerhoff now provides the first in-depth analysis. After examining a variety of attempted definitions, he proceeds to argue for a new (...) understanding of ontological categories, according to which they are systematizations of our knowledge of the world rather than essential characteristics of the world itself. Metaphysicians will find his work highly stimulating. (shrink)

We define a first-order theory FIN which has a recursive axiomatization and has the following two properties. Each finite part of FIN has finite models. FIN is strong enough to develop that part of mathematics which is used or has potential applications in natural science. This work can also be regarded as a consistency proof of this hitherto informal part of mathematics. In FIN one can count every set; this permits one to prove some new probabilistic theorems.

The bulk of the present book has not been published previously though Chapters II and IV are based in part on two earlier papers of mine: "The Influence of Harald H!1lffding's Philosophy on Niels Bohr's Interpretation of Quantum Mechanics", which appeared in Danish Yearbook of Philosophy, 1979, and "The Bohr-H!1lffding Relationship Reconsidered", published in Studies in History and Philosophy of Science, 1988. These two papers comple ment each other, and in order to give the whole issue a more extended treatment (...) I have sought, in the present volume by drawing on relevant historical material, to substantiate the claim that H!1lffding was Bohr's mentor. Besides containing a detailed account of Bohr's philosophy, the book, at the same time, serves the purpose of making H!1lffding' s ideas and historical significance better known to a non-Danish readership. During my work on this book I have consulted the Royal Danish Library; the National Archive of Denmark and the Niels Bohr Archive, Copenhagen, in search of relevant material. I am grateful for permission to use and quote material from these sources. Likewise, I am indebted to colleagues and friends for commenting upon the manuscript: I am especially grateful to Professor Henry Folse for our many discussions during my visit to New Orleans in November-December 1988 and again here in Elsinore in July 1990.

In "De malorum subsistentia" chs 30-7, Proclus criticizes the view that evil is to be identified with matter. His main target is Plotinus' account in Enn. I,8 [51]. Proclus denies that matter is the cause of evil in the soul, and that it is evil or a principle of evil. According to Proclus, matter is good, because it is produced by the One. Plotinus' doctrine of matter-evil is the result of a different conception of emanation, according to which matter does (...) not revert to its principle. Proclus claims that to posit a principle of evil either amounts to a coarse dualism, or makes the Good ultimately responsible for evil. Plotinus does not seem to be able to escape the latter consequence, if he is to remain committed to the Neoplatonic conception of causation. Plotinus equated matter with privation and said it is a kind of non-being that is the contrary of substance, thus violating fundamental Aristotelian tenets. Proclus reinstates Aristotelian orthodoxy, as does Simplicius in his "Commentary on the Categories." It is possible that lamblichus was the source of both Proclus and Simplicius, and that he was the originator of the parhypostasis theory and the inventor of the anti-Plotinian arguments. (shrink)

For the Critical Theory tradition of the Frankfurt School, rationalisation is a central concept that refers to the socio-cultural closure of capitalist modernity due to the proliferation of technical, ‘instrumental’ rationality at the expense of some form of political reason. This picture of rationalisation, however, hinges on a separation of technology and politics that is both empirically and philosophically problematic. This article aims to re-conceptualise the rationalisation thesis through a survey of research from science and technology studies and the conceptual (...) framework of Niklas Luhmann's systems theory. It argues that rationalisation indeed exhibits a logic of closure, namely the ‘operational closure’ of sociotechnical systems of measurement, but that this closure in fact produces the historical logics of technical reason and, paradoxically, also generates spaces of critical-political openness. This opens up the theoretical and practical opportunity of connecting the politically just to the technically efficient. (shrink)

A number of well-developed theories shed light on the question, under what circumstances our beliefs enjoy epistemic justification. Yet, comparatively little is known about epistemic defeat--when new information causes the loss of epistemic justification. This book proposes and defends a detailed account of epistemic defeaters. The main kinds of defeaters are analyzed in detail and integrated into a general framework that aims to explain how beliefs lose justification. It is argued that defeaters introduce incompatibilities into a noetic system and thereby (...) prompt a structured re-evaluation process that makes a justified reinstatement of the defeated belief impossible. The account is then applied to the topic of disagreement, where it is used in an argument for conciliationism, as well as a new explanation for higher-order defeat. Throughout the book, the notion of defeat is the center of attention, while a number of new issues are discussed at the intersections of defeat and justification. Specifically, new problems are raised for broadly internalist accounts of defeat, a fully descriptive reliabilist account of defeat is provided, and the case for normative defeat is revisited.

This book provides the reader with an analysis of backward causation. The notion of backward causation faces many different paradoxes that threaten to make the notion inconsistent or incoherent. The book denies that these pose a real threat. It developed a theory of causation according to which the orientation of causation is not dependent on the direction of time. In this process it takes issues with David Lewis' contrafactual analysis of causation, and denies that the direction of time is determined (...) by irreversible processes . Likewise the book argues that the conceptual possibility of backward causation requires that the future is just as real as the past and present. Finally the book considers what the physical processes may look like if backward causation not only a a conceptual possibility but also a physical possibility. The conclusion is that no normal matter can possibly participate in backward causal processes. Instead objects moving backwards in time seem to posses negative mass and energy, a kind of objects that would be different from both ordinary objects and hypothetical tachyons. (shrink)

Students of Thomas Aquinas have so far lacked a comprehensive study of his doctrine of the transcendentals. This volume fills this lacuna, showing the fundamental character of the notions of being, one, true and good for his thought. The book inquires into the beginnings of the doctrine in the thirteenth century and explains the relation of the transcendental way of thought to Aquinas's conception of metaphysics. It analyzes 'Being', 'One', 'True', 'Good' and 'Beautiful' individually and discusses their importance for the (...) philosophical knowledge of God. Medieval Philosophy and the Transcendentals: The Case of Thomas Aquinas is intended as a contribution to the question 'What is philosophy in the Middle Ages?' It argues that the doctrine of the transcendentals is essential for understanding medieval philosophy. (shrink)

This paper develops a probabilistic reconstruction of the No Miracles Argument in the debate between scientific realists and anti-realists. The goal of the paper is to clarify and to sharpen the NMA by means of a probabilistic formalization. In particular, we demonstrate that the persuasive force of the NMA depends on the particular disciplinary context where it is applied, and the stability of theories in that discipline. Assessments and critiques of "the" NMA, without reference to a particular context, are misleading (...) and should be relinquished. This result has repercussions for recent anti-realist arguments, such as the claim that the NMA commits the base rate fallacy. It also helps to explain the persistent disagreement between realists and anti-realists. (shrink)

Sometimes also called retro causation. A common feature of our world seems to be that in all cases of causation, the cause and the effect are placed in time so that the cause precedes its effect temporally. Our normal understanding of causation assumes this feature to such a degree that we intuitively have great difficulty imagining things differently. The notion of backward causation, however, stands for the idea that the temporal order of cause and effect is a mere contingent feature (...) and that there may be cases where the cause is causally prior to its effect but where the temporal order of the cause and effect is reversed with respect to normal causation, i.e. there may be cases where the effect temporally, but not causally, precedes its cause.

In this paper, I present a solution to the problem that the need to accommodate the phenomenon of epistemic defeat poses for reliabilism. Defeaters are supposed to remove justification for previously justified beliefs. According to standard process reliabilism, the justification of a belief depends on the reliability of a process that is already completed when a defeater for that belief is obtained. It is hard to see, then, how a defeater can affect reliabilist justification, if that justification, from the perspective (...) of the defeater, lies wholly in the past. What is more, undercutting defeaters plausibly defeat by generating incompatibilities with higher-order propositions :105–118, 2014; Melis in Philos Stud 170:433–442, 2014). This is hard to integrate with reliabilism which explicitly denies higher-order conditions for justification. I argue that both of these phenomena can be accommodated by it via what I call the “Replacement Principle”: when a defeater is obtained, it generates either a logical incompatibility or a doxastic incompatibility. The resulting tension is registered and initiates a reasoning process that compares the epistemic support for the defeater with that for the defeated belief. This process may replace the original reliable formation process as a doxastic base for the defeated belief. If the defeater is not given its due weight in the reasoning process, that process was unreliable and if the defeated belief is retained as a result, it will be unjustified. This is intuitively the right result. Since reasoning is reliable, only if it is rational, the account manages to capture the intuition that disregarding a defeater would be irrational without having to make rationality a condition for justification. Replacement is not only plausible on causal pictures of doxastic basing, but also required in order to allow for the possibility of belief reevaluation in general and is therefore not an ad hoc addition to reliabilism, but rather part of its inherent explanatory resources.

Jeffrey Friedman broaches a number of criticisms of Libertarianism as a conceptual basis for opposing the extensive modern welfare state, examining several variants and concluding that they are fundamentally unsupported. He opts for a “consequentialist” view of foundations. Nevertheless, he thinks that the modem welfare state is subject to effective critique along such lines. But rational contractarian individualism works and does provide foundations for libertarianism, while “consequentialism” is an ill‐defined theory.that is quite unpromising for the proposed critique; nevertheless, Friedman's empirical (...) and economic critique of the welfare state is valid.

In recent years, the use of historical cases in philosophy of science has become a proper topic of reflection. In this article I will contribute to this research by means of a discussion of one very famous example of case-based philosophy of science, namely the debate on the London & London model of superconductivity between Cartwright, Suárez and Shomar on the one hand, and French, Ladyman, Bueno and Da Costa on the other. This debate has been going on for years, (...) without any satisfactory resolution. I will argue here that this is because both sides impose on the historical case a particular philosophical conception of scientific representation that does not do justice to the historical facts. Both sides assume, more specifically, that the case concerns the discovery of a representational connection between a given experimental insight – the Meissner effect – and the diamagnetic meaning of London and London’s new equations of superconductivity. I will show, however, that at the time of the Londons’ publication, neither the experimental insight nor the meaning of the new equations was established: both were open for discussion and they were stabilized only later. On the basis of this historical discussion, I will then propose an alternative approach to the case study: the case should not be seen as a site of confrontation between pre-existing philosophical accounts, but rather as a way to historically elaborate and develop philosophical concepts. I will then show how approaching the historical episode in this way suggests an alternative approach to the philosophical study of representation, according to which it involves the establishment, over time, of a stable connection between constellations of different elements that, through discussion and engagement with alternative views and approaches, come to constitute phenomenon and meaning.

Niels Bohr and Philosophy of Physics: Twenty-First Century Perspectives examines the work, influences and legacy of the Nobel Prize physicist and philosopher of experiment Niels Bohr. While covering Bohr's groundbreaking contribution to quantum mechanics, this collection reveals the philosophers who influenced his work. Linking him to the pragmatist C.I. Lewis and the Danish philosopher Harald Høffding, it draws strong similarities between Bohr's philosophy and the Kantian way of thinking. Addressing the importance of Bohr's views of classical concepts, it discusses how (...) his interpretation of quantum mechanics now compares with a variety of issues that have arisen only since his lifetime, including decoherence and other non-collapse arguments. Balancing historical themes with contemporary ideas, Niels Bohrs and Philosophy of Physics reveals Bohr's on-going contribution to the philosophy of science and confirms his place in the history of philosophy.

Belief in the afterlife is still very much alive in Western civilisation, even though the truth of its existence is no longer universally accepted. Surprisingly, however, heaven, hell and the immortal soul were all ideas which arrived relatively late in the ancient world. Originally Greece and Israel - the cultures that gave us Christianity - had only the vaguest ideas of an afterlife. So where did these concepts come from and why did they develop? In this fascinating, learned, but highly (...) readable book, Jan N. Bremmer - one of the foremost authorities on ancient religion - takes a fresh look at the major developments in the Western imagination of the afterlife, from the ancient Greeks to the modern near-death experience.

According to influential accounts of scientific method, such as critical rationalism, scientific knowledge grows by repeatedly testing our best hypotheses. But despite the popularity of hypothesis tests in statistical inference and science in general, their philosophical foundations remain shaky. In particular, the interpretation of non-significant results—those that do not reject the tested hypothesis—poses a major philosophical challenge. To what extent do they corroborate the tested hypothesis, or provide a reason to accept it? Popper sought for measures of corroboration that could (...) adequately answer this question. According to Popper, corroboration is different from probability-raising, and grounded in the predictive success and testability of a hypothesis. As such, corroboration becomes an indicator of the scientific value of a hypothesis and guides our practical preferences over hypotheses that have been subjected to severe tests. This article proves two impossibility results for corroboration measures based on statistical relevance. The generality of these results shows that Popper’s qualitative characterization of corroboration must be misguided. I explore what a more promising and scientifically useful concept of corroboration could look like. (shrink)

The aim of this article is to provide a historical response to Michel Janssen’s (2009) claim that the special theory of relativity establishes that relativistic phenomena are purely kinematical in nature, and that the relativistic study of such phenomena is completely independent of dynamical considerations regarding the systems displaying such behavior. This response will be formulated through a historical discussion of one of Janssen's cases, the experiments carried out by Walter Kaufmann on the velocity-dependence of the electron's mass. Through a (...) discussion of the different responses formulated by early adherents of the principle of relativity (Albert Einstein, Max Planck, Hermann Minkowski and Max von Laue) to these experiments, it will be argued that the historical development of the special theory of relativity argues against Janssen's historical presentation of the case, and that this raises questions about his general philosophical claim. It will be shown, more specifically, that Planck and Einstein developed a relativistic response to the Kaufmann experiments on the basis of their study of the dynamics of radiation phenomena, and that this response differed significantly from the response formulated by Minkowski and Laue. In this way, it will be argued that there were, at the time, two different approaches to the theory of relativity, which differed with respect to its relation to theory, experiment, and history: Einstein's and Planck's heuristic approach, and Minkowski's and Laue's normative approach. This indicates that it is difficult to say, historically speaking, that the special theory of relativity establishes the kinematical nature of particular phenomena. Instead, it will be argued that the theory of relativity should not be seen as a theory but rather as outlining an approach, and that the nature of particular scientific phenomena is something that is open to scientific debate and dispute.

Many philosophers consider explanation to be objective such that facts explain facts independently of human beings. This paper rejects such an ontological view and argues in favor of an epistemic view, named the pragmatic-rhetorical view, according to which explanations depend on our knowledge and are grounded in the public or scientific discourse.

Recent research in Baroque Scholastic and early modern meditational exercises has demonstrated similarity between Descartes’s Meditations and St. Teresa of Ávila’s El Castillo Interior. While there is growing agreement on the influence of Catholic meditations on Descartes, the extent of Teresa’s role is debated. Instead of discussing the full extent of Teresa’s influence, this paper concentrates on one example of the considered influence: the skeptical scenario of demonic deception, having clear anticipation in Teresa’s work where the exercitant faces off against (...) deceiving demonic forces, which confound and temporarily halt the meditative progress. The paper analyzes Teresa’s use of deceptive demons and its influence on the Cartesian Evil Demon scenario, while contrasting both with a discussion of demonic deception in the late Medieval and Baroque Scholastic context, arguing that demonological discussions in 1500s allowed both Teresa’s and Descartes’s deceivers to not only cause diversions but to make the deception laborious to resist.

G. A. Cohen's Rescuing Justice and Equality proposes that both concepts need rescuing from the work of John Rawls. Especially, it is concerned with Rawls' famous second principle of justice according to which social primary goods should be distributed equally unless an unequal distribution is to the benefit of the worst off. The question is why this would ever be necessary if all parties are just. Cohen and I agree that Rawls cannot really justify inequalities on the basis given. But (...) he also thinks equality is the correct analysis of justice, though he provides no actual direct arguments for this. He does, however, provide a striking analytical argument claiming that fundamental principles of justice must be fact insensitive, and that Rawls's view of justice violates this requirement. I argue that the requirement is itself misconceived and that principles of justice cannot possibly be fact insensitive in the sense developed by Cohen. Few philosophers share this view of Cohen's—which I argue is due to several conceptual mistakes. With these ironed out, the contractarian view, broadly speaking, is seen to be plausible and powerful. Meanwhile Cohen appears to embrace intuitionism, a stance that cannot possibly be acceptable in social philosophy. In the end, Cohen is successful in arguing that Rawls cannot have what he wants, but neither is Cohen successful in claiming that justice is equality. (shrink)

Inductive logic generalizes the idea of logical entailment and provides standards for the evaluation of non-conclusive arguments. A main application of inductive logic is the generalization of observational data to theoretical models. In the empirical sciences, the mathematical theory of statistics addresses the same problem. This paper argues that there is no separable purely logical aspect of statistical inference in a variety of complex problems. Instead, statistical practice is often motivated by decision-theoretic considerations and resembles empirical science.

New computer systems of discovery create a research program for logic and philosophy of science. These systems consist of inference rules and control knowledge that guide the discovery process. Their paths of discovery are influenced by the available data and the discovery steps coincide with the justification of results. The discovery process can be described in terms of fundamental concepts of artificial intelligence such as heuristic search, and can also be interpreted in terms of logic. The traditional distinction that places (...) studies of scientific discovery outside the philosophy of science, in psychology, sociology, or history, is no longer valid in view of the existence of computer systems of discovery. It becomes both reasonable and attractive to study the schemes of discovery in the same way as the criteria of justification were studied: empirically as facts, and logically as norms. (shrink)

It is widely thought that Robert Nozick’s views on rectification of past injustices are of critical importance to his theory of distributive justice, even perhaps justifying wholesale redistributive taxes in the present because of the undoubted injustices that have pervaded much past history. This essay undertakes to correct this impression—not mostly by disagreeing with Nozick’s claims, but nevertheless proceeding on basic libertarian theory. Of enormous importance is the role of putative innocents, who are defrauded by miscreants carefully covering their tracks (...) so that these recipients have no reason to think they are buying stolen property. But of equal importance is simply that the duty to rectify past injustices is not comparable to the original duty to respect property rights in the first place. (shrink)

The pragmatic theory of explanation is an attempt to see explanation as a linguistic response to a cognitive problem where the content of the response depends on the context of the scientific inquiry. The present paper draws on the rhetorical situation, as it is defined by Loyld Bitzer, in order to understand how the context may influence the content as well as the acceptability of the response.

The ability to anticipate the future is of great benefit to any organism. Whenever such a foreseeing takes place, it typically happens because an organism has been able to learn about some regularity in the past and then uses this information to expect some happenings in the future. Modern human beings have perfected this capacity far beyond any other animal by getting to know the laws by which nature operates. But it is still based on past experience that even human (...) beings are able to say something about the future. So every form of anticipation of the future relies on inductive reasoning based on knowledge of causal processes in the past. Both these processes and the processes by which we learn to anticipate the future are common in the sense that it is always an earlier cause that brings about a later effect. The ability to anticipate depends on the fact that our cognitive faculties only work on information that stems from the past. Had it been possible for us to receive reliable information about the future, the ability of anticipation might not have existed or might have been less faulty than it sometimes is. (shrink)
