In the methodology of scientific research programs (MSRP) there are important features on the problem of prediction, especially regarding novel facts. In his approach, Imre Lakatos proposed three different levels on prediction: aim, process, and assessment. Chapter 5 pays attention to the characterization of prediction in the methodology of research programs. Thus, it takes into account several features: (1) its pragmatic characterization, (2) the logical perspective as a proposition, (3) the epistemological component, (4) its role in the appraisal of research (...) programs, and (5) its place as a value for scientific research. -/- The notion of “novel facts” is highly relevant in his conception, where several aspects are involved: the directions of novel facts, the different kinds of novelty, and the transition from six possible options of “novel facts” to four choices. Thereafter, the prediction of novel facts as the criterion of appraisal is considered. On the one hand, this requires analyzing the theoretical, empirical, and heuristic possibilities of appraisal; and, on the other, whether there is an overemphasis on the role of prediction in methodology of scientific research programs. As a consequence, there is an analysis of Lakatos’ criterion of appraisal in MSRP and economics. (shrink)

The purpose of this essay is to defend the deductive-nomological model of explanation against a number of criticisms that have been made of it. It has traditionally been thought that scientific explanations were causal and that scientific explanations involved deduction from laws. In recent years, however, this three-fold identity has been challenged: there are, it is argued, causal explanations that are not scientific, scientific explanations that are not deductive, deductions from laws that are neither causal explanations nor scientific explanations, and (...) causal explanations that involve no deductions from laws. The aim of the present essay is to defend the traditional identities, and to show that the more recent attempts at invalidating them fail in their object. More specifically, this essay argues that a Humean version of the deductive-nomological model of explanation can be defended as the correct account of scientific explanation of individual facts and processes, and as the correct account of causal explanations of individual facts and processes. The deductive-nomological model holds that to explain an event E, say that a is G, one must find some initial conditions C, say that a is F, and a law or theory T such that T and C jointly entail E, and both are essential to the deduction.

: The notion of a delusion occupies a central place in psychotherapy. The presence of delusional thinking in a patient is often regarded as indicative of psychosis. And yet, the nature of a delusion is still widely disputed. The difficulty of defining a delusion has proved so difficult that some prominent authors have declared the task impossible. The aim of this paper is to offer a characterisation of delusional systems of thought. In this paper is argued that delusions, unlike scientific (...) explanations and the explanations generally offered by common sense, fail to minimise that which requires explanation. In the first part of the paper, difficulties with extant accounts will be discussed. In the following parts, the author’s own account of delusional thoughts will be developed and some difficult cases considered. It will be argued that delusions differ from more typical beliefs in the number of things that they leave unexplained. Delusions, unlike those beliefs we typically see as rational, bring about an increase in the number of things requiring explanation. Keywords: Delusions; Epistemology; Analysis; Explanation; Rationality Aspetti epistemologici del pensiero delirante Riassunto: La nozione di delirio occupa una posizione centrale nell’ambito della psicoterapia. La presenza del pensiero delirante in un paziente è considerata spesso come un indice di psicosi. E, tuttavia, la natura del delirio non è ancora oggetto di ampio accordo tra gli studiosi. La difficoltà nel definire il delirio si è mostrata talmente ostica che diversi importanti studiosi hanno dichiarato questo compito impossibile. Lo scopo di questo lavoro è quello di offrire una caratterizzazione dei sistemi di pensiero delirante. Si sosterrà che i deliri, diversamente dalle spiegazioni scientifiche e da quelle offerte generalmente dal senso comune, non riescono a ridurre quanto necessita di una spiegazione. Nella prima parte del lavoro, saranno discusse le difficoltà degli approcci correnti. Nelle parti seguenti verrà proposto l’approccio dell’autore ai pensieri deliranti e verranno presi in esame alcuni casi complessi. Si sosterrà che i deliri si distinguono dai casi più tipici di credenza per il numero di cose che lasciano senza spiegazione. I deliri, diversamente dalle credenze che tipicamente consideriamo irrazionali, determinano un incremento del numero di cose che richiedono una spiegazione. Parole chiave: Delirio; Epistemologia; Analisi; Spiegazione; Razionalità. (shrink)

The claim that scientific explanation is deductive has been attacked on both systematic and historical grounds. This paper briefly defends the claim against the systematic attack. Essential to this defence is a distinction between perfect and imperfect explanation. This distinction is then used to illuminate the differences and similarities between Aristotelian (anthropomorphic) explanations of certain facts and those of classical mechanics. In particular, it is argued that when one attempts to fit classical mechanics into the Aristotelian framework the latter becomes (...) structurally incoherent. It is suggested that this, together with the fact that classical mechanics embodied the first piece of perfect knowledge, accounts, in part at least, for the historical fact of the rapid demise of the Aristotelian patterns as the new science developed. On the basis of this discussion, the inadequacies of the attack on the deductive model on historical grounds by Toulmin come to be seen. (shrink)

This article is intended to contribute to the discussion on the meaning of volunteering by investigating voluntary work from the viewpoint of volunteers active in Swedish civil society organizations.Meaning refers both to the cognitive meaning of concepts and to the perceived meaning in life. The aim to uncover the predicates that people attribute to the concept is an attempt to anatomize volunteering as a social construct. Five predicates emerged and they make up the phenomenological structure of volunteering. By contextualizing this (...) structure in contemporary Swedish society, it is demonstrated that the conceptual meaning of volunteering has significance for its existential meaning. The volunteers say that their authenticity is confirmed through the voluntary work since they are making themselves manifest in public. Following Hannah Arendt, the reasons for this is that authenticity demands that the volunteers conduct their actions in a public realm where their actions acquire an intrinsic value as neither coerced nor instrumental.

In this article I am going to reconstruct Stephen Toulmin’s procedural theory of concepts and explanations in order to develop two overlooked ideas from his philosophy of science: methods of representations and inferential techniques. I argue that these notions, when properly articulated, could be useful for shedding some light on how scientific reasoning is related to representational structures, concepts, and explanation within scientific practices. I will explore and illustrate these ideas by studying the development of the notion of instantaneous speed (...) during the passage from Galileo’s geometrical physics to analytical mechanics. At the end, I will argue that methods of representations could be considered as constitutive of scientific inference; and I will show how these notions could connect with other similar ideas from contemporary philosophy of science like those of models and model-based reasoning.

Scientists and laypeople alike use the sense of understanding that an explanation conveys as a cue to good or correct explanation. Although the occurrence of this sense or feeling of understanding is neither necessary nor sufficient for good explanation, it does drive judgments of the plausibility and, ultimately, the acceptability, of an explanation. This paper presents evidence that the sense of understanding is in part the routine consequence of two well-documented biases in cognitive psychology: overconfidence and hindsight. In light of (...) the prevalence of counterfeit understanding in the history of science, I argue that many forms of cognitive achievement do not involve a sense of understanding, and that only the truth or accuracy of an explanation make the sense of understanding a valid cue to genuine understanding.

This article investigates the challenges posed by the reliability of knowledge in neurophenomenology and its connection to reality. Neurophenomenological research seeks to understand the intricate relationship between human consciousness, cognition, and the underlying neural processes. However, the subjective nature of conscious experiences presents unique epistemic challenges in determining the reliability of the knowledge generated in this research. Personal factors such as beliefs, emotions, and cultural backgrounds influence subjective experiences, which vary from individual to individual. On the other hand, scientific knowledge (...) aims to uncover universal truths based on empirical observations and objective principles. Reconciling the subjective and objective realms presents a significant challenge in determining the reliability of knowledge generated through neurophenomenological research. This article aims to examine the inherent limitations and challenges of neurophenomenological research to shed light on the complexities involved in understanding the nature of knowledge itself. This article highlights that the ontological implications of the reliability of knowledge in neurophenomenology arise from the question of how subjective experiences relate to objective reality. Understanding the neural correlates and mechanisms behind subjective experiences can provide insight into the underlying ontological nature of consciousness. (shrink)

The basic theory of scientific understanding presented in Sections 1–2 exploits three main ideas.First, that to understand a phenomenonP (for a given agent) is to be able to fitP into the cognitive background corpusC (of the agent).Second, that to fitP intoC is to connectP with parts ofC (via arguments in a very broad sense) such that the unification ofC increases.Third, that the cognitive changes involved in unification can be treated as sequences of shifts of phenomena inC. How the theory fits (...) typical examples of understanding and how it excludes spurious unifications is explained in detail. Section 3 gives a formal description of the structure of cognitive corpuses which contain descriptive as well as inferential components. The theory of unification is then refined in the light of so called puzzling phenomena, to enable important distinctions, such as that between consonant and dissonant understanding. In Section 4, the refined theory is applied to several examples, among them a case study of the development of the atomic model. The final part contains a classification of kinds of understanding and a discussion of the relation between understanding and explanation. (shrink)

The interpretive plasticity of Kuhn’s philosophical work has been reinforced by readings informed by other philosophical, historiographic or sociological projects. This paper highlights several aspects of Kuhn’s work that have been neglected by such readings. First, Kuhn’s early contribution to several subsequent philosophical developments has been unduly neglected. Kuhn’s postscript discussion of “exemplars” should be recognized as one of the earliest versions of a conception of theories as “mediating models.” Kuhn’s account of experimental practice has also been obscured by readings (...) that assimilate his views to Quinean holism. Second, three distinctive Kuhnian themes have been insufficiently recognized. Kuhn’s challenge to received philosophical views has been domesticated by reading him as offering an alternative conception of scientific knowledge. Kuhn is better understood as rejecting knowledge-centric accounts altogether, in favor of understanding the practice of research. Kuhn’s conception of that activity, as conceptual “articulation,” has accordingly also not been given its due. Finally, Kuhn’s career-long insistence on the mutual accountability of philosophy of science and the philosophy of mind and language calls attention to the extent to which these fields have now drifted apart.

Remarks on the Relations between Neurophysiology and Psychology. In the last decades of Analytical Philosophy, contributions to the so-called mind-body-problem have been suffering by several serious methodological misunderstandings: they have failed, for instance, to distinguish between explanations of particular and strictly general ("necessary") properties and between two important senses of existential statements; and they have overlooked the role conceptual explanations play in the development of science. Changing our methodological premisses, we should be able to put questions like that of the (...) relation between (neuro)physiological and psychological phenomena in a new way - and we should be able to see that such newly understood questions allow answers which evade the pitfalls of both reductionist and holistic positions. The paper tries to illustrate and to defend these contentions by reference to a very elementary example: the rational re-building of our concepts to identify behaviour by which a subject controls the position of his body in space.

The topic of the presence, legitimacy and epistemic worth of narrative explanations in different kinds of scientific discourse has already enjoyed several revivals within related discussions in contemporary philosophy of science. In fact, we have recently witnessed a more extensive, more unprejudiced and ambitious attention to narrative modes of making science. I think we need a systematic theoretical framework in order to categorize these different functions of narratives and understand their role in scientific explanatory and justificatory practice. My claim is (...) that some distinctions and analytic tools developed within the field of contemporary Argumentation Theory might be of help. (shrink)

Descartes held that practicing mathematics was important for developing the mental faculties necessary for science and a virtuous life. Otherwise, he maintained that the proper uses of mathematics were extremely limited. This article discusses his reasons which include a theory of education, the metaphysics of matter, and a psychologistic theory of deductive reasoning. It is argued that these reasons cohere with his system of philosophy.

In this paper, I propose that the debate in epistemology concerning the nature and value of understanding can shed light on the role of scientific idealizations in producing scientific understanding. In philosophy of science, the received view seems to be that understanding is a species of knowledge. On this view, understanding is factive just as knowledge is, i.e., if S knows that p, then p is true. Epistemologists, however, distinguish between different kinds of understanding. Among epistemologists, there are those who (...) think that a certain kind of understanding—objectual understanding—is not factive, and those who think that objectual understanding is quasi-factive. Those who think that understanding is not factive argue that scientific idealizations constitute cognitive success, which we then consider as instances of understanding, and yet they are not true. This paper is an attempt to draw lessons from this debate as they pertain to the role of idealizations in producing scientific understanding. I argue that scientific understanding is quasi-factive.

Scientific revolution is a widely known concept. But does revolution really occur in science? Change through revolution means that present thinking does not retain anything from the past, because everything is thrown away due to the revolution. Does this pattern of change really correspond to the history of science? There is another pattern which is called evolution. This writing will show that process of evolution rather than revolution presents the real situation of scientific change. According to this concept, science grows (...) as an organic species grows in certain environment. An organism is different from its every former stage, yet it remains the same organism throughout its life. In the same way, we will find both change and continuity in scientific growth. (shrink)

Knowledge of many facts does not amount to understanding unless one also has a sense of how the facts fit together. This aspect of coherence among scientific observations and theories is usually overlooked in summaries of scientific method, since the emphasis is on justification and verification rather than on understanding. I argue that the inter-theoretic coherence, as the hallmark of understanding, is an essential and informative component of any accurate description of science.

In this article I discuss the justification of scientific change and argue that it rests on different sorts of invariance. Against this background I consider notions of observation, meaning, and regulative standards. I sketch an account of the rationale of scientific change which preserves the merits and avoids the shortcomings of the approach of Feyerabend, Hanson, Kuhn, Toulmin, and others. Each of these writers would hold that transitions from one scientific tradition to another force radical changes in what is observed, (...) in the meanings of the terms employed, and in the metastandards involved. They would claim that "incommensurable" replacement is what does, and should, occur during scientific "revolutions." Such writers, however, have trouble in comparing different scientific theories. My account permits different theories to be compared in various ways. These comparisons, I argue, are possible through appeal to "first-level" and "second-level" invariance. In this connection I argue that observation, meaning, and regulative standards should be, and in fact usually are, nontrivially invariant with respect to scientific change. (shrink)

Genetic epistemology analyzes the growth of knowledge both in the individual person (genetic psychology) and in the socio-historical realm (the history of science). But what the relationship is between the history of science and genetic psychology remains unclear. The biogenetic law that ontogeny recapitulates phylogeny is inadequate as a characterization of the relation. A critical examination of Piaget's Introduction à l'Épistémologie Généntique indicates these are several examples of what I call stage laws common to both areas. Furthermore, there is at (...) least one example of a paradoxical inverse relation between the two — geometry. Both similarities and differences between the two domains require an explanation, a developmental explanation. Although such an explanation seems to be psychological in nature, it is not merely empirical but also normative (since psychology is both factual and normative according to Piaget). Hence genetic epistemology need not be reduced to psychology (narrowly conceived), but rather should be seen as being both empirical and normative and thus similar to certain types of contemporary philosophy of science.

Recently, a book was published, the sole purpose of which was to discourage researchers from using the scientific phenomenological method. The author had previously been critical of nurses who had used the scientific phenomenological method but in the new book he goes after the originators of different methods of scientific phenomenological research and attempts to criticize them severely. In this review I defend only the scientific phenomenological method that is strictly based upon the thought of Edmund Husserl. Given the entirely (...) negative project of only critiquing phenomenologically grounded scientific research, one would expect the author to be sensitive to the cautions historians and philosophers of science speak about when one attempts to criticize concepts and procedures that belong to a different research community. Paley, an empiricist, uses empirical criteria to criticize phenomenological work.Moreover, given the entirely negative project of critiquing phenomenologically grounded scientific research one would expect the author to be knowledgeable about phenomenology and the innovative research practices used by a new research community. However, the author has only a thin, superficial understanding of phenomenology. One gets the impression that he only reads phenomenology in order to critique it. He displays an outsider’s understanding of it which means that his criticisms of it are faulty because he does not know how to think and dwell within the phenomenological framework; he does not understand “discovery-oriented” research and he keeps judging such research according to criteria from the “context of verification” perspective which are the wrong criteria for “discovery-oriented” research; he denigrates and reduces nursing research strategies because he interprets them to be based on pragmatic motivations only. He does not even grant that nurses can have authentic scientific motivations for seeking phenomenologically based methods; he uses unfair rhetorical strategies in the sense that he uses strategies himself that he criticizes when others use them. The review below documents what has been summarized here. (shrink)

Thesis: Art like science radically affects our perceiving and thinking, and the two are substantially alike in that together--along with an inherited "natural" language system with which they overlap--they enable us to articulate the world. Science has been advanced as the measure of all things: scientific realism. By implication, art pertains to beauty, science truth. Science effects conceptual break-throughs, changes our models of natural order. On the contrary (I argue), as a nonverbal symbol system art similarly affects paradigm-induced expectations. Substantively (...) there is no difference in the way each enables us to articulate or measure the world: symbolic realism. The myth of resemblance as a criterion of representation--imitation as a one-one relation--has, at least since the time of Plato, obscured this truth. Once the distinction between representational and nonrepresentational art falls, the true nature of artist (like scientist) as maker is illumined. The artist, the scientist (disciplinarian), the cosmologist (those responsible for the formulation of so-called natural languages--in time all of us) make the world or, what practically amounts to the same thing, the known, perceived world. This is the claim of the symbolic realist. Is symbolic realism itself only a watershed? What implication does this critique have for assessing the role of the philosopher today? (shrink)

Imre Lakatos gained fame in the English-speaking world as a follower and critic of philosopher of science Karl Popper. However, Lakatos’ background involved other philosophical and scientific sources from his native Hungary. Lakatos surreptitiously used Hegelian Marxism in his works on philosophy of science and mathematics, disguising it with the rhetoric of the Popper school. He also less surreptitiously incorporated, particularly in his treatment of mathematics, work of the strong tradition of heuristics in twentieth century Hungary. Both his Marxism and (...) his emphasis on heuristics contained a view of science and mathematics that contrasted with the mainstream of Anglo-American philosophy of science. Both involved a dynamic view of science, whether historical or psychological, and an emphasis on practice as opposed to static, formal representations of scientific theories. (shrink)

By briefly reviewing three well-known scientific revolutions in fundamental physics (the discovery of inertia, of special relativity and of general relativity), I claim that problems that were supposed to be crying for a dynamical explanation in the old paradigm ended up receiving a structural explanation in the new one. This claim is meant to give more substance to Kuhn’s view that revolutions are accompanied by a shift in what needs to be explained, while suggesting at the same time the existence (...) of a pattern that is common to all of the discussed case-studies. It remains to be seen whether also quantum mechanics, in particular entanglement, conforms to this pattern. (shrink)

I conceptualise the role of dualities in quantum gravity, in terms of their functions for theory construction. I distinguish between two functions of duality in physical practice: namely, discovering and describing ‘equivalent physics’, versus suggesting ‘new physics’. I dub these the ‘theoretical’ versus the ‘heuristic’ functions of dualities. The distinction seems to have gone largely unnoticed in the philosophical literature: and it exists both for dualities, and for the more general relation of theoretical equivalence. The paper develops the heuristic function (...) of dualities: illustrating how they can be used, if one has any luck, to find and formulate new theories. I also point to the different physical commitments about the theories in question that underlie these two functions. I show how a recently developed schema for dualities articulates the differences between the two functions. (shrink)

The main cognitive target of Ecology is the functional analysis of the ecological processes and systems. It does not suppose, meanwhile, that these processes and systems are designed systems and processes like individual leaving beings. The Ecology, likewise Physiology, is constitutively guided by the presupposition of a privileged state , to be explained, that it is the persistence of the systems and processes that she studied; and its functional analyses obey to this presupposition. Ecology supposes an ideal of natural order (...) , under which consideration this privileged state is thinking as an improbable state of things and, for that, needed of explanation; and, in what concerns this latter point, the analogy between Ecology and Physiology can also result instructive.

El arquetipo vertebrado delineado por Richard Owen a mediados del Siglo XIX fue un modelo concebido para pautar el análisis morfológico de los seres vivos dentro de los lineamientos definidos por la idea de una unidad de composición cuando ella se aplicaba al caso específico de los vertebrados.

Firstly, in this article it is examined the nature of the putative remarks concerning evolution of species that are found in the works that Richard Owen published before 1858; and then it is made the same thing with the few and vague evolutionist conjectures that Owen certainly made after the public presentation of Natural Selection Theory. Regarding the former topic, the goal will be to highlight the ambiguity of those Owen’s remarks, and concerning the latter topic what is looked for (...) is to show that, when he explained his transmutationist thesis, Owen didn’t go beyond a pious theistic evolutionism, without postulating any mechanism of evolutionary change and remaining faithful to Design Theology praised by Paley.

El objetivo de este trabajo es poner al descubierto los principales valores cognitivos y epistemológicos desde los que Warren Weaver puso en marcha el Programa de Biología Experimental, un programa que llevado a cabo desde la presidencia de la división de ciencias naturales de la Fundación Rockefeller, marcó y condicionó en buena medida el posterior desarrollo de la investigación biológica. Para tal fin se mostrará, en primer lugar, cómo fue la llegada de Weaver a la Fundación Rockefeller, así como las (...) razones bajo las cuáles el consejo de esa institución decidió entre 1932 y 1933 dar prioridad a las investigaciones biomédicas, y la manera por la cual lo hicieron. En un segundo momento, el más extenso e importante, veremos algunos de los elementos más significativos de la perspectiva epistemológica y cognoscitiva de de Weaver. Finalizaremos viendo cómo esa perspectiva, desarrollada en conexión con el Programa de Biología Experimental, inter-actuó con la visión reduccionista de la biología a la que el programa parecía apuntar. The aim of this article is to uncover the main cognitive and epistemological values that influenced Warren Weaver in starting the Experimental Biology Program, a program carried out from the time that he became president of the Natural Sciences Division of the Rockefeller Foundation, and which significantly marked and conditioned the subsequent development of biological research. To this end, we first describe the arrival of Warren Weaver at the Rockefeller Foundation, and the reasons for which the Board of this Foundation, between 1932 and 1933, decided to prioritize biomedical research, and the manner in which they did so. Then, secondly, in the largest and most important part of the article, we will present some of the most significant elements of Weaver's epistemological and cognitive perspective. Finally, we will show how this perspective, developed in connection with the Experimental Biology Program, interacted with the reductionist view of biology to which the program seemed to point.

The articulation of an overarching account of scientific explanation has long been a central preoccupation for the philosophers of science. Although a while ago the literature was dominated by two approaches—a causal account and a unificationist account—today the consensus seems to be that the causal account has won. In this paper, I challenge this consensus and attempt to revive unificationism. More specifically, I aim to accomplish three goals. First, I add new criticisms to the standard anti-unificationist arguments, in order to (...) motivate the need for a revision of the doctrine. Second, and most importantly, I sketch such a revised version. Then I argue that, contrary to widespread belief, the causal account and this revised unificationist account of explanation are compatible. Moreover, I also maintain that the unificationist account has priority, since a most satisfactory theory of explanation can be obtained by incorporating the causal account, as a sub-component of the unificationist account. The driving force behind this reevaluation of the received view in the philosophy of explanation is a reconsideration of the role of scientific understanding. (shrink)

Aristotle's rule of proportions of the factors of motion, presented in VII 5 of the Physics, characterizes Aristotelian force. Observing that the locomotion to which Aristotle applied the Rule is the motion produced by manual labor, I develop an interpretation of the factors of motion that reveals that Aristotelian force is Newtonian power. An alternate interpretation of the Rule by Toulmin and Goodfield implicitly identifies Aristotelian force with Newtonian force. In order to account for the absence of an acceleration in (...) the rate of forced motion, they incorporate into the Rule the medium's resistance to motion due to viscosity as an additional factor. The resulting interpretations of the original factors of motion lose the exactness the power interpretation grants them. The constant rate of forced motion follows immediately from the power interpretation. It is also compatible with the Rule's description of the motion that is produced by the sum of forces. (shrink)

In this book Martin Bunzl considers the prospects for a general and comprehensive account of explanation, given the variety of interests that prompt explanations in science. Bunzl argues that any successful account of explanation must deal with two very different contexts - one static and one dynamic. Traditionally, theories of explanation have been built for the former of these two contexts. That is to say, they are designed to show how it is that a 'finished' body of scientific knowledge can (...) be put to explanatory use. But finished sciences are few and far between. Real 'explanation' also occurs in a dynamical context in which questions are asked and answers are given as theories are in the process of being constructed. Here, Bunzl argues that attending to explanation produced under these dynamic circumstances undermines prominent features of the theory of explanation produced in the traditional static context.

This inaugural handbook documents the distinctive research field that utilizes history and philosophy in investigation of theoretical, curricular and pedagogical issues in the teaching of science and mathematics. It is contributed to by 130 researchers from 30 countries; it provides a logically structured, fully referenced guide to the ways in which science and mathematics education is, informed by the history and philosophy of these disciplines, as well as by the philosophy of education more generally. The first handbook to cover the (...) field, it lays down a much-needed marker of progress to date and provides a platform for informed and coherent future analysis and research of the subject. -/- The publication comes at a time of heightened worldwide concern over the standard of science and mathematics education, attended by fierce debate over how best to reform curricula and enliven student engagement in the subjects There is a growing recognition among educators and policy makers that the learning of science must dovetail with learning about science; this handbook is uniquely positioned as a locus for the discussion. -/- The handbook features sections on pedagogical, theoretical, national, and biographical research, setting the literature of each tradition in its historical context. Each chapter engages in an assessment of the strengths and weakness of the research addressed, and suggests potentially fruitful avenues of future research. A key element of the handbook’s broader analytical framework is its identification and examination of unnoticed philosophical assumptions in science and mathematics research. It reminds readers at a crucial juncture that there has been a long and rich tradition of historical and philosophical engagements with science and mathematics teaching, and that lessons can be learnt from these engagements for the resolution of current theoretical, curricular and pedagogical questions that face teachers and administrators.

Ao deduzir causa de efeito, ele acreditava chegar a uma causa primeira de todas as coisas. A essa primeira causa de tudo, onde toda a ordem e leis (...) tiveram início, a qual para ele assume um caráter divino, Newton aponta para um Deus sábio e poderoso e responsável pela ordem inteligente e pela a harmonia das leis físicas e universais de tudo o que existe – Deus como criador e preservador da ordem do universo.

This thesis studies the role of conceptual content in inference and reasoning. The first two chapters offer a theoretical and historical overview of the relation between inference and meaning in philosophy and psychology. In particular, a critical analysis of the formality thesis, i.e., the idea that rational inference is a rule-based and topic-neutral mechanism, is advanced. The origins of this idea in logic and its influence in philosophy and cognitive psychology are discussed. Chapter 3 consists of an analysis of the (...) relationship between inference and representation. It is argued that inference has to be studied from a pluralistic per- spective due to its dependence on different formats of representing information. The following four chapters apply conceptual spaces, a formal theory of concepts within cognitive semantics, to three concept-based inference-types. First, an explication of Sellars notion of material inference is advanced. Later, the model is extended to account for nonmonotonic inference by studying the role expectations in reasoning. Finally, a conceptual space-model of category-based induction is presented. This model predicts most of the empirical properties of this psychological phenomenon and subsumes some of the previous theories in psychology. It is stated that the explanatory fruitfulness of this new approach is evidence for the failure of the formality thesis and calls for a unified model of rational inference that puts semantics at center stage. The last chapter of the thesis discusses how inference and concepts interact in scientific reasoning, which makes constant use of hybrid symbolic structures for representing conceptual information. Stephen Toulmin’s notions of method of representation and inferential technique are developed and applied in a case study about the emergence of the notion of instantaneous speed during the passage from geometrical physics to analytical mechanics. It is claimed that this analysis provides support to the pluralistic perspective for theorizing about reasoning. (shrink)

This work consists of two parts. Part I will be a contribution to a philo- sophical discussion of the nature of causal explanation. It will present my contrastive counterfactual theory of causal explanation and show how it can be used to deal with a number of problems facing theories of causal explanation. Part II is a contribution to a discussion of the na- ture of interest explanation in social studies of science. The aim is to help to resolve some controversies (...) concerning interest explanation by explicating the concept of interest and its explanatory uses by using the account of explanation developed in Part I.

Selection explanations explain some non-accidental generalizations in virtue of a selection process. Such explanations are not particulaizable - they do not transfer as explanations of the instances of such generalizations. This is unlike many explanations in the physical sciences, where the explanation of the general fact also provides an explanation of its instances (i.e. standard D-N explanations). Are selection explanations (e.g. in biology) therefore a different kind of explanation? I argue that to understand this issue, we need to see that (...) a standard D-N explanation of some non-accidental generalization (al Fs are Gs) may also ipso facto explain its contrapositive (all non-Gs are non-Fs), but the explanation is particularizable with respect to the former but not to the latter. This can be seen by noting that the Raven Paradox counterexample to the H-D model of confirmation also generates a counterexample to the D-N model of explanation (all ravens are black does not explain why the non-black shoe is a non-raven). In such cases it is natural to take the generalization with the positive predicates to have a particularizable explanation. However, this need not be the case, and in selection explanations it is the generalization with the positive predicates whose explanation is no particularizable. Thus there is no need to suppose that selection explanations are fundamentally different. (shrink)

This article demonstrates that theory-laden perception is a pure fiction of some philosophers of science and does not in fact exist. It shows by examples from L. Fleck that non-neutral or person-bound observation is an important source of scientific knowledge and suggests that we can explain those changes in scientific knowledge that are caused by divergent perceptions of different observers by means of differences in the repertoires of visual concepts of the respective observers. Visual concept is introduced by means of (...) a performance model of perception.

The aim ofthis article is to present the explication of these concepts, and of their relationships, made within the framework of Sneedean or Metatheoretical Structuralism (Balzer et al. 1987), and of their application to a case from the realm of biology: Population Dynamics. The analysis carried out will make it possible to support, contrary to what some philosophers of science in general and of (...) biology in particular hold, the following claims: a) there are "laws" in biological sciences, b) many of the heterogeneous and different "models" of biology can be accommodated under some "theory", and c) this is exactly what confers great unifying power to biological theories.

I characterize the deductivist ideal of justification and, following to a great extent Toulmin’s work The Uses of Argument, I try to explain why this ideal is erroneous. Then I offer an alternative model of justification capable of making our claims to knowledge about substantial matters sound and reasonable. This model of justification will be based on a conception of justification as the result of good argumentation, and on a model of argumentation which is a pragmatic linguistic reconstruction of Toulmin’s (...) model of argument.
