The aim of this study was to explore the influences, processes and environments that shaped the practice of European nurses for indigenous New Zealand (NZ) Māori communities who were being overwhelmed by introduced infectious diseases. Historical data were accessed from multiple archival sources and analysed through the lens of colonial theory. Through their work early last century, NZ nurses actively gained professional status and territory through their work with Māori. By living and working alongside Māori, they learned to practise in (...) new ways that influenced Māori health. By developing a new role in new professional territory, nurses extended their practice to include health promotion as well as disease prevention. Māori survival from epidemics improved, and the population grew over that period. For Māori, however, Eurocentric care alleviated their immediate health problems, but the detrimental impact of the mechanisms of colonisation overall has continued to the present day. (shrink)

This text provides a critique of the subjective Bayesian view of statistical inference, and proposes the author's own error-statistical approach as an alternative framework for the epistemology of experiment. It seeks to address the needs of researchers who work with statistical analysis.

There is a growing call for greater public involvement in establishing science and technology policy, in line with democratic ideals. A variety of public participation procedures exist that aim to consult and involve the public, ranging from the public hearing to the consensus conference. Unfortunately, a general lack of empirical consideration of the quality of these methods arises from confusion as to the appropriate benchmarks for evaluation. Given that the quality of the output of any participation exercise is difficult to (...) determine, the authors suggest the need to consider which aspects of the process are desirable and then to measure the presence or quality of these process aspects. To this end, a number of theoretical evaluation criteria that are essential for effective public participation are specified. These comprise two types: acceptance criteria, which concern features of a method that make it acceptable to the wider public, and process criteria, which concern features of the process that are liable to ensure that it takes place in an effective manner. Future research needs to develop instruments to measure these criteria more precisely and identify the contextual and environmental factors that will mediate the effectiveness of the different participation methods.

Imprecise definition of key terms in the “public participation” domain have hindered the conduct of good research and militated against the development and implementation of effective participation practices. In this article, we define key concepts in the domain: public communication, public consultation, and public participation. These concepts are differentiated according to the nature and flow of information between exercise sponsors and participants. According to such an information flow perspective, an exercise’s effectiveness may be ascertained by the efficiency with which full, (...) relevant information is elicited from all appropriate sources, transferred to all appropriate recipients, and combined to give an aggregate/consensual response. Key variables that may theoretically affect effectiveness—and on which engagement mechanisms differ—are identified and used to develop a typology of mechanisms. The resultant typology reveals four communication, six consultation, and four participation mechanism classes. Limitations to the typology are discussed, and future research needs identified.

Despite the widespread use of key concepts of the Neyman–Pearson (N–P) statistical paradigm—type I and II errors, significance levels, power, confidence levels—they have been the subject of philosophical controversy and debate for over 60 years. Both current and long-standing problems of N–P tests stem from unclarity and confusion, even among N–P adherents, as to how a test's (pre-data) error probabilities are to be used for (post-data) inductive inference as opposed to inductive behavior. We argue that the relevance of error probabilities (...) is to ensure that only statistical hypotheses that have passed severe or probative tests are inferred from the data. The severity criterion supplies a meta-statistical principle for evaluating proposed statistical inferences, avoiding classic fallacies from tests that are overly sensitive, as well as those not sensitive enough to particular errors and discrepancies. Introduction and overview 1.1 Behavioristic and inferential rationales for Neyman–Pearson (N–P) tests 1.2 Severity rationale: induction as severe testing 1.3 Severity as a meta-statistical concept: three required restrictions on the N–P paradigm Error statistical tests from the severity perspective 2.1 N–P test T(): type I, II error probabilities and power 2.2 Specifying test T() using p-values Neyman's post-data use of power 3.1 Neyman: does failure to reject H warrant confirming H?

While many philosophers of science have accorded special evidential significance to tests whose results are "novel facts", there continues to be disagreement over both the definition of novelty and why it should matter. The view of novelty favored by Giere, Lakatos, Worrall and many others is that of use-novelty: An accordance between evidence e and hypothesis h provides a genuine test of h only if e is not used in h's construction. I argue that what lies behind the intuition that (...) novelty matters is the deeper intuition that severe tests matter. I set out a criterion of severity akin to the notion of a test's power in Neyman-Pearson statistics. I argue that tests which are use-novel may fail to be severe, and tests that are severe may fail to be use-novel. I discuss the 1919 eclipse data as a severe test of Einstein's law of gravity.

Although both philosophers and scientists are interested in how to obtain reliable knowledge in the face of error, there is a gap between their perspectives that has been an obstacle to progress. By means of a series of exchanges between the editors and leaders from the philosophy of science, statistics and economics, this volume offers a cumulative introduction connecting problems of traditional philosophy of science to problems of inference in statistical and empirical modelling practice. Philosophers of science and scientific practitioners (...) are challenged to reevaluate the assumptions of their own theories - philosophical or methodological. Practitioners may better appreciate the foundational issues around which their questions revolve and thereby become better 'applied philosophers'. Conversely, new avenues emerge for finally solving recalcitrant philosophical problems of induction, explanation and theory testing. (shrink)

Via the existential questioning outlook supplied by the Grasshopper’s three visions as relevant to the fate of humankind – oblivion, delusion, and really magnificent games – this article seeks to alleviate some of the ambiguity surrounding Bernard Suits’ provocative claim that Utopian existence is fundamentally concerned with game-playing. Specifically, after proposing an interpretation of Suits’ parable designed to enrich the logical intelligibility of his Utopian thesis, I advance the suggestion that the Grasshopper’s picture of people playing really magnificent games is (...) reasonably interpreted as a clue that the philosopher’s quest to discern games worthy of a Utopian might very well be that which saves humanity from the desolate oblivion-delusion paradox erected as a consequence of the initial two visions.

The notion that the metric field in general relativity can be understood as a property of space-time rests on a feature of the theory sometimes called universal coupling—the claim that rods and clocks “measure” the metric in a way that is independent of their constitution. It is pointed out that this feature is not strictly a consequence of the central dynamical tenets of the theory, and argued that the metric field would better be regarded as a field in space-time, rather (...) than as the very fabric of space-time itself.

The key problem in the controversy over group selection is that of defining a criterion of group selection that identifies a distinct causal process that is irreducible to the causal process of individual selection. We aim to clarify this problem and to formulate an adequate model of irreducible group selection. We distinguish two types of group selection models, labeling them type I and type II models. Type I models are invoked to explain differences among groups in their respective rates of (...) production of contained individuals. Type II models are invoked to explain differences among groups in their respective rates of production of distinct new groups. Taking Elliott Sober's model as an exemplar, we argue that although type I models have some biological importance--they force biologists to consider the role of group properties in influencing the fitness of organisms--they fail to identify a distinct group-level causal selection process. Type II models if properly framed, however, do identify a group-level causal selection process that is not reducible to individual selection. We propose such a type II model and apply it to some of the major candidates for group selection. (shrink)

The Lysis is one of Plato's most engaging but also puzzling dialogues; it has often been regarded, in the modern period, as a philosophical failure. The full philosophical and literary exploration of the dialogue illustrates how it in fact provides a systematic and coherent, if incomplete, account of a special theory about, and special explanation of, human desire and action. Furthermore, it shows how that theory and explanation are fundamental to a whole range of other Platonic dialogues and indeed to (...) the understanding of the corpus as a whole. Part One offers an analysis of, or running commentary on, the dialogue. In Part Two Professors Penner and Rowe examine the philosophical and methodological implications of the argument uncovered by the analysis. The whole is rounded off by an epilogue of the relation between the Lysis and some other Platonic texts. (shrink)

The concept of public participation is one of growing interest in the UK and elsewhere, with a commensurate growth in mechanisms to enable this. The merits of participation, however, are difficult to ascertain, as there are relatively few cases in which the effectiveness of participation exercises have been studied in a structured manner. This seems to stem largely from uncertainty in the research community as to how to conduct evaluations. In this article, one agenda for conducting evaluation research that might (...) lead to the systematic acquisition of knowledge is presented. This agenda identifies the importance of defining effectiveness and of operationalizing one’s definition. The article includes analysis of the nature of past evaluations, discussion of potential difficulties in the enactment of the proposed agenda, and discussion of some potential solutions. (shrink)

The growing availability of computer power and statistical software has greatly increased the ease with which practitioners apply statistical methods, but this has not been accompanied by attention to checking the assumptions on which these methods are based. At the same time, disagreements about inferences based on statistical research frequently revolve around whether the assumptions are actually met in the studies available, e.g., in psychology, ecology, biology, risk assessment. Philosophical scrutiny can help disentangle 'practical' problems of model validation, and conversely, (...) a methodology of statistical model validation can shed light on a number of issues of interest to philosophers of science.

The question of acceptability in respect to the strategic foul in sport has provoked a rich and seemingly irreconcilable dispute with normative theorists currently divided amongst three schools of thought including formalism, conventionalism and interpretivism. In this paper, I seek to transcend the three-way intellectual stalemate portrayed in the literature via a consideration as to whether or not the strategic foul qualifies as ‘Utopian’. More specifically, after demonstrating that Bernard Suits’ theory of game-playing is fully capable of embracing all three (...) rival accounts, I seek to end the normative debate altogether via a conceptual analysis of the strategic foul as unacceptable via the higher-order point of view afforded by essentialism.

In The Grasshopper: Games, Life, and Utopia, Suits maintains the following two theses: game-playing is defined as ‘activity directed towards bringing about a specific state of affairs, using only means permitted by rules, where the rules prohibit more efficient in favour of less efficient means, and where such rules are accepted just because they make possible such activity’ and ‘game playing is what makes Utopia intelligible.’ Observing that these two theses cannot be jointly maintained absent paradox, this essay explores the (...) logical possibility that if is true, then must be false. More specifically, in the tradition of conceptual analysis it is argued that Suits’ definition of game-playing is too narrow inasmuch as it excludes really magnificent Utopian games of significance.

Much light has been shed on important features of teaching and learning by Alasdair MacIntyre's writings. Yet there are experiences that are crucial to teaching and learning that are unaddressed in MacIntyre's arguments; experiences that reveal education as a distinctive kind of practice. This paper examines one kind of such experience: an experience I call ‘being pulled up short’. Drawing on the work of Hans-Georg Gadamer and Gerald L. Bruns, I analyse an example of teaching King Lear to argue that (...) being pulled up short is a unique experience of disorientation that cannot be taught merely by pedagogical skill, including the modern tools and approaches provided by constructivist learning theory and meta-cognition. The paper concludes by identifying challenges that being pulled up short poses for the education of disposition, and for the aims and activities of teaching. (shrink)

In seeking general accounts of evidence, confirmation, or inference, philosophers have looked to logical relationships between evidence and hypotheses. Such logics of evidential relationship, whether hypothetico-deductive, Bayesian, or instantiationist fail to capture or be relevant to scientific practice. They require information that scientists do not generally have (e.g., an exhaustive set of hypotheses), while lacking slots within which to include considerations to which scientists regularly appeal (e.g., error probabilities). Building on my co-symposiasts contributions, I suggest some directions in which a (...) new and more adequate philosophy of evidence can move. (shrink)

The Toulmin diagram layout is very familiar and widely used, particularly in the teaching of critical thinking skills. The conventional box-and-arrow diagram is equally familiar and widespread. Translation between the two throws up a number of interesting challenges. Some of these challenges represent slightly different ways of looking at old and deep theoretical questions. Others are diagrammatic versions of questions that have already been addressed in artificial intelligence models of argument. But there are further questions that are posed as a (...) specific result of examining the diagram inter-translation problem. These three classes of problems are discussed. To the first class are addressed solutions based on engineering pragmatism; to the second class are addressed solutions drawn from the appropriate literature; and to the third class, fuller exploration is offered justifying the approaches taken in developing solutions that offer both pragmatic utility and theoretical interest. Finally, these solutions are explored briefly in the context of the Araucaria system, showing the ways in which analysts can tackle arguments either using one diagrammatic style or another, or even a combination of the two.

Research on detrimental workplace behaviors has increased recently, predominantly focusing on justice issues. Research from the integrity testing literature, which is grounded in trait theory, has not received as much attention in the management literature. Trait theory, agency theory, and psychological contracts theory each have different predictions about employee performance that is harmful to the organization. While on the surface they appear contradictory, this paper describes how each can be integrated to increase our understanding of detrimental workplace behaviors.

I argue that the Bayesian Way of reconstructing Duhem's problem fails to advance a solution to the problem of which of a group of hypotheses ought to be rejected or "blamed" when experiment disagrees with prediction. But scientists do regularly tackle and often enough solve Duhemian problems. When they do, they employ a logic and methodology which may be called error statistics. I discuss the key properties of this approach which enable it to split off the task of testing auxiliary (...) hypotheses from that of appraising a primary hypothesis. By discriminating patterns of error, this approach can at least block, if not also severely test, attempted explanations of an anomaly. I illustrate how this approach directs progress with Duhemian problems and explains how scientists actually grapple with them. (shrink)

This study explores the complex relationships between anomalous experiences, mental health, creativity, and psi within a sample of 113 visual artists in three art schools. The main objective was to assess whether psi could play a role in the emergence of anomalous experiences and their association with mental health and creativity. Participants took part in a retro-priming task, already used by Bem to assess unconscious precognitive abilities. They then completed three questionnaires evaluating anomalous experiences, mental health, and creativity. The results (...) show no significant effect on the retro-priming task, but the number of anomalous experiences reported by each participant was significantly correlated with their retro-priming performance. Creativity did not correlate with retro-priming, except for one subscale, the use of analogies. Anomalous experiences as a whole were correlated with mental health and creativity, in keeping with the high rate of unusual experiences previously reported in artistic populations. The theoretical implication of these findings and possible directions for future studies are discussed. (shrink)

Adaptations can occur at different hierarchical levels (e.g., cells and multicellular organisms), but it can be difficult to identify the level(s) of adaptation in specific cases. A major problem is that selection at a lower level can filter up, creating the illusion of selection at a higher level. We use optimality modeling of the volvocine algae to explore the emergence of genuine group (i.e., colony-level) adaptations. We find that it is helpful to develop an explicit model for what group fitness (...) would be in the absence of group-level relationships between traits and group fitness. We call this “counterfactual fitness,” because in many actual cases of interest there are group-level relationships. Once counterfactual fitness is modeled, the difference between effects that filter up and genuine group selection is explicit and so, therefore, is the distinction between apparent and genuine group adaptations. We call the latter group-specific adaptations. Recognizing group-specific adaptations is important because only group-specific adaptations would cause the lower-level units (cells in this case) to be maladapted if they were to leave the group and enter a global cell-level population. Thus, as group-specific adaptations evolve, they create selective pressure for increased cohesiveness and individuality of groups. This article suggests that group-specific adaptations could be present in the simplest, earliest branching colonial volvocine species, which do not have distinct specialized cells. The article also makes predictions about the kind of empirical evidence needed to support or refute the hypothesis that a particular trait is a group-level adaptation. (shrink)

The issues of double-counting, use-constructing, and selection effects have long been the subject of debate in the philosophical as well as statistical literature. I have argued that it is the severity, stringency, or probativeness of the test—or lack of it—that should determine if a double-use of data is admissible. Hitchcock and Sober ([2004]) question whether this ‘severity criterion' can perform its intended job. I argue that their criticisms stem from a flawed interpretation of the severity criterion. Taking their criticism as (...) a springboard, I elucidate some of the central examples that have long been controversial, and clarify how the severity criterion is properly applied to them. Severity and Use-Constructing: Four Points (and Some Clarificatory Notes) 1.1 Point 1: Getting beyond ‘all or nothing’ standpoints 1.2 Point 2: The rationale for prohibiting double-counting is the requirement that tests be severe 1.3 Point 3: Evaluate severity of a test T by its associated construction rule R 1.4 Point 4: The ease of passing vs. ease of erroneous passing: Statistical vs. ‘Definitional’ probability The False Dilemma: Hitchcock and Sober 2.1 Marsha measures her desk reliably 2.2 A false dilemma Canonical Errors of Inference 3.1 How construction rules may alter the error-probing performance of tests 3.2 Rules for accounting for anomalies 3.3 Hunting for statistically significant differences Concluding Remarks.

Traditionally, acts of sportsmanship have been upheld as worthy of praise. The purpose of this paper is to discern whether Bernard Suits’ Grasshopper -- in "The Grasshopper: Games, Life and Utopia" -- would share this approval. The paper begins with a conceptual analysis of good sportspersonship. From this, four action categories are identified including good sportspersonship in the forms of game desertion, changing the game, not trying, and lusory self-handicapping. A strategy for evaluation is derived from the Grasshopper’s theory. Game-playing (...) is defined as action reflecting lusory attitude acknowledgement. Game-spoiling is introduced as action demonstrating lusory attitude abandonment. Three of the four actions categories are characterized as game-spoiling including good sportspersonship in the forms of game desertion, changing the game, and not trying. It is concluded that genuine good sportspersonship is characterized solely by altruistic forms of lusory self-handicapping. (shrink)

Recently, scholars have looked more closely at the philosophical importance of the imaginative and literary aspects of Plato's writing, and have begun to appreciate the methods of ancient philosophers and commentators who studied Plato. This study brings together leading philosophical and literary scholars to investigate these new-old approaches.

While orthodox (Neyman-Pearson) statistical tests enjoy widespread use in science, the philosophical controversy over their appropriateness for obtaining scientific knowledge remains unresolved. I shall suggest an explanation and a resolution of this controversy. The source of the controversy, I argue, is that orthodox tests are typically interpreted as rules for making optimal decisions as to how to behave--where optimality is measured by the frequency of errors the test would commit in a long series of trials. Most philosophers of statistics, however, (...) view the task of statistical methods as providing appropriate measures of the evidential-strength that data affords hypotheses. Since tests appropriate for the behavioral-decision task fail to provide measures of evidential-strength, philosophers of statistics claim the use of orthodox tests in science is misleading and unjustified. What critics of orthodox tests overlook, I argue, is that the primary function of statistical tests in science is neither to decide how to behave nor to assign measures of evidential strength to hypotheses. Rather, tests provide a tool for using incomplete data to learn about the process that generated it. This they do, I show, by providing a standard for distinguishing differences (between observed and hypothesized results) due to accidental or trivial errors from those due to systematic or substantively important discrepancies. I propose a reinterpretation of a commonly used orthodox test to make this learning model of tests explicit. (shrink)

BackgroundHealth data-driven activities have become central in diverse fields (research, AI development, wearables, etc.), and new ethical challenges have arisen with regards to privacy, integrity, and appropriateness of use. To ensure the protection of individuals’ fundamental rights and freedoms in a changing environment, including their right to the protection of personal data, we aim to identify the ethical approaches adopted by scientists during intensive data exploitation when collecting, using, or sharing peoples’ health data.MethodsTwelve scientists who were collecting, using, or sharing (...) health data in different contexts in Sweden, were interviewed. We used systematic expert interviews to access these scientists’ specialist knowledge, and analysed the interviews with thematic analysis. Phrases, sentences, or paragraphs through which ethical values and norms were expressed, were identified and coded. Codes that reflected similar concepts were grouped, subcategories were formulated, and categories were connected to traditional ethical approaches.ResultsThrough several examples, the respondents expressed four different ethical approaches, which formed the main conceptual categories: consideration of consequences, respect for rights, procedural compliance, and being professional.ConclusionsTo a large extent, the scientists’ ethical approaches were consistent with ethical and legal principles. Data sharing was considered important and worth pursuing, even though it is difficult. An awareness of the complex issues involved in data sharing was reflected from different perspectives, and the respondents commonly perceived a general lack of practical procedures that would by default ensure ethical and legally compliant data collection and sharing. We suggest that it is an opportune time to move on from policy discussions to practical technological ethics-by-design solutions that integrate these principles into practice. (shrink)

Kuhn maintains that what marks the transition to a science is the ability to carry out ‘normal’ science—a practice he characterizes as abandoning the kind of testing that Popper lauds as the hallmark of science. Examining Kuhn's own contrast with Popper, I propose to recast Kuhnian normal science. Thus recast, it is seen to consist of severe and reliable tests of low-level experimental hypotheses (normal tests) and is, indeed, the place to look to demarcate science. While thereby vindicating Kuhn on (...) demarcation, my recasting of normal science is seen to tell against Kuhn's view of revolutionary science. (shrink)

Since the advent of the women's movement, women have made unprecedented gains in almost every field, from politics to the professions. Paradoxically, doctors and mental health professionals have also seen a staggering increase in the numbers of young women suffering from an epidemic of depression, eating disorders, and other physical and psychological problems. In The Cost of Competence, authors Brett Silverstein and Deborah Perlick argue that rather than simply labeling individual women as, say, anorexic or depressed, it is time (...) to look harder at the widespread prejudices within our society and child-rearing practices that lead thousands of young women to equate thinness with competence and success, and femininity with failure. They argue that continuing to treat depression, anxiety, anorexia and bulimia as separate disorders in young women can, in many cases, be a misguided approach since they are really part of a single syndrome. Furthermore, their fascinating research into the lives of forty prominent women from Elizabeth I to Eleanor Roosevelt show that these symptoms have been disrupting the lives of bright, ambitious women not for decades, but for centuries. Drawing on all the latest findings, rare historical research, cross-cultural comparisons, and their own study of over 2,000 contemporary women attending high schools and colleges, the authors present powerful new evidence to support the existence of a syndrome they call anxious somatic depression. Their investigation shows that the first symptoms usually surface in adolescence, most often in young women who aspire to excel academically and professionally. Many of the affected women grew up feeling that their parents valued sons over daughters. They identified intellectually with their successful fathers, not with their traditional homemaker mothers. Disordered eating is one way of rejecting the feminine bodies they perceive as barriers to achievement and recognition. Silverstein and Perlick uncover medical descriptions matching their diagnosis in Hippocratic texts from the fourth century B.C., in anthropological studies of Africa, Asia, and Latin America, and in case studies of many noted psychologists and psychiatrists, including the "hysteric" patients Freud used to develop his theories on psychoanalysis. They have also discovered that statistics on disordered eating, depression, and a host of other symptoms soared in eras in which women's opportunities grew--particularly the 1920s, when record numbers of women entered college and the workforce, the boyish silhouette of the flapper became the feminine ideal, and anorexia became epidemic, and again from the 1970s to the present day. The authors show that identifying this devastating syndrome is a first step toward its prevention and cure. The Cost of Competence presents an urgent message to parents, educators, policymakers, and the medical community on the crucial importance of providing young women with equal opportunity, and equal respect.

Theories of statistical testing may be seen as attempts to provide systematic means for evaluating scientific conjectures on the basis of incomplete or inaccurate observational data. The Neyman-Pearson Theory of Testing (NPT) has purported to provide an objective means for testing statistical hypotheses corresponding to scientific claims. Despite their widespread use in science, methods of NPT have themselves been accused of failing to be objective; and the purported objectivity of scientific claims based upon NPT has been called into question. The (...) purpose of this paper is first to clarify this question by examining the conceptions of (I) the function served by NPT in science, and (II) the requirements of an objective theory of statistics upon which attacks on NPT's objectivity are based. Our grounds for rejecting these conceptions suggest altered conceptions of (I) and (II) that might avoid such attacks. Second, we propose a reformulation of NPT, denoted by NPT*, based on these altered conceptions, and argue that it provides an objective theory of statistics. The crux of our argument is that by being able to objectively control error frequencies NPT* is able to objectively evaluate what has or has not been learned from the result of a statistical test.

Understanding good design requires addressing the question of what units undergo natural selection, thereby becoming adapted. There is, therefore, a natural connection between the formal Darwinism project (which aims to connect population genetics with the evolution of design and fitness maximization) and levels of selection issues. We argue that the formal Darwinism project offers contradictory and confusing lines of thinking concerning level(s) of selection. The project favors multicellular organisms over both the lower (cell) and higher (social group) levels as the (...) level of adaptation. Grafen offers four reasons for giving such special status to multicellular organisms: (1) they lack appreciable within-organism cell selection, (2) they have multiple features that appear contrived for the same purpose, (3) they possess a set of phenotypes, and (4) they leave offspring according to their phenotypes. We discuss why these rationales are not compelling and suggest that a more even-handed approach, in which multicellular organisms are not assumed to have special status, would be desirable for a project that aims to make progress on the foundations of evolutionary theory.

We review Evolution and the Levels of Selection by Samir Okasha. This important book provides a cohesive philosophical framework for understanding levels-of-selections problems in biology. Concerning evolutionary transitions, Okasha proposes that three stages characterize the shift from a lower level of selection to a higher one. We discuss the application of Okasha’s three-stage concept to the evolutionary transition from unicellularity to multicellularity in the volvocine green algae. Okasha’s concepts are a provocative step towards a more general understanding of the major (...) evolutionary transitions; however, the application of certain ideas to the volvocine model system is not straightforward.

Cartwright argues for being a realist about theoretical entities but non-realist about theoretical laws. Her reason is that while the former involves causal explanation, the latter involves theoretical explanation; and inferences to causes, unlike inferences to theories, can avoid the redundancy objection--that one cannot rule out alternatives that explain the phenomena equally well. I sketch Cartwright's argument for inferring the most probable cause, focusing on Perrin's inference to molecular collisions as the cause of Brownian motion. I argue that either the (...) inference she describes fails to be a genuinely causal one, or else it too is open to the redundancy objection. However, I claim there is a way to sustain Cartwright's main insight: that it is possible to avoid the redundancy objection in certain cases of causal inference from experiments (e.g., Perrin). But, contrary to Cartwright, I argue that in those cases one is able to infer causes only by inferring some theoretical laws about how they produce experimental effects. (shrink)

There are two reasons, I claim, scientists do and should ignore standard philosophical theories of objective evidence: Such theories propose concepts that are far too weak to give scientists what they want from evidence, viz., a good reason to believe a hypothesis; and They provide concepts that make the evidential relationship a priori, whereas typically establishing an evidential claim requires empirical investigation.
