Physical superpositions exist both in classical and in quantum physics. However, what is exactly meant by ‘superposition’ in each case is extremely different. In this paper we discuss some of the multiple interpretations which exist in the literature regarding superpositions in quantum mechanics. We argue that all these interpretations have something in common: they all attempt to avoid ‘contradiction’. We argue in this paper, in favor of the importance of developing a new interpretation of superpositions which takes into account contradiction, (...) as a key element of the formal structure of the theory, “right from the start”. In order to show the feasibility of our interpretational project we present an outline of a paraconsistent approach to quantum superpositions which attempts to account for the contradictory properties present in general within quantum superpositions. This approach must not be understood as a closed formal and conceptual scheme but rather as a first step towards a different type of understanding regarding quantum superpositions. (shrink)

This paper argues for Kantian “universalism,” according to which the subject of empirical cognition is not merely individual, but universal. In the first section, I consider the limitations of Hume’s individualist view of the subject of judgment, which is able to explain how another person exerts power over my judgments, but cannot explain how what she says can challenge or support my judgments. In the second section, I argue that Kant’s universalism accounts for the possibility of rational support both among (...) different judgments in me, and among judgments of different subjects. The third section looks at the consequences of universalism for Kant’s account of testimony. I argue that on Kant’s view, it does not matter whether I learn something from my own experience or from your experience. Testimony thus does not emerge in Kant’s philosophy as a significant topic. In the fourth section, I argue that the enlightenment project of overcoming prejudice and acquiring wisdom makes it imperative that knowledge be not only universally shareable, but also actually shared among members of an epistemic community.

In Good White People: The Problem with Middle-Class White Anti-Racism, Shannon Sullivan considers: "What can white people do to help end racial injustice?". As one response to this question, Sullivan argues that prescribing "white shame" and "white guilt" is useless, since promoting these ideas leads to self-hate and inaction on the part of white people. In this paper, I agree with Sullivan, but for different reasons. I argue that assuming that white people can feel ashamed simply about being white within (...) our current society is unfounded. I will maintain that the project of "promoting white shame" is fraught to begin with, and show the significance of this finding for conversations about white people's role in... (shrink)

Background: In the ever-changing and complex healthcare environment, nurses encounter challenging situations that may involve a clash between their personal and professional values resulting in a profound impact on their practice. Nevertheless, there is a dearth of literature on how nurses develop their personal–professional values. Aim: The aim of this study was to understand how nurses develop their foundational values as the base for their value system. Research design: A constructivist grounded theory methodology was employed to collect multiple data sets, (...) including face-to-face focus group and individual interviews, along with anecdote and reflective stories. Participants and research context: Fifty-four nurses working across various nursing settings in Indonesia were recruited to participate. Ethical considerations: Ethics approval was obtained from the Monash University Human Ethics Committee, project approval number 1553. Findings: Foundational values acquisition was achieved through family upbringing, professional nurse education and organisational/institutional values reinforcement. These values are framed through three reference points: religious lens, humanity perspective and professionalism. This framing results in a unique combination of personal–professional values that comprise nurses’ values system. Values are transferred to other nurses either in a formal or informal way as part of one’s professional responsibility and customary social interaction via telling and sharing in person or through social media. Discussion: Values and ethics are inherently interweaved during nursing practice. Ethical and moral values are part of professional training, but other values are often buried in a hidden curriculum, and attained and activated through interactions during nurses’ training. Conclusion: Developing a value system is a complex undertaking that involves basic social processes of attaining, enacting and socialising values. These processes encompass several intertwined entities such as the sources of values, the pool of foundational values, value perspectives and framings, initial value structures, and methods of value transference.

In this study, we explore the future of work by examining differences in productivity when teams are composed of only humans or both humans and machine agents. Our objective was to characterize the similarities and differences between human and human–machine teams as they work to coordinate across their specialized roles. This form of research is increasingly important given that machine agents are becoming commonplace in sociotechnical systems and playing a more active role in collaborative work. One particular class of machine (...) agents, bots, is being introduced to these systems to facilitate both taskwork and teamwork. We investigated the association between bots and productivity outcomes in open source software development through an analysis of hundreds of project teams. The presence of bots in teams was associated with higher levels of productivity and higher work centralization in addition to greater amounts of observed communication. The adoption of bots in software teams may have tradeoffs, in that doing so may increase productivity, but could also increase workload. We discuss the theoretical and practical implications of these findings for advancing human–machine teaming research. (shrink)

Nicholas Maxwell takes on the ambitious project of explaining, both epistemologically and metaphysically, the physical universe and human existence within it. His vision is appealing; he unites the physical and the personal by means of the concepts of aim and value, which he sees as the keys to explaining traditional physical puzzles. Given the current popularity of theories of goal-oriented dynamical systems in biology and cognitive science, this approach is timely. But a large vision requires firm and nuanced arguments (...) to support it. Here Maxwell's work is weakest; his arguments for contingent mind-body identity and for free will, on which his larger theory depends, are inadequate. The book is valuable both for its comprehensive view of the human condition and its mysteries, and for its demonstration of the difficulties in making such a view coherent. (shrink)

There is increasing emphasis on the need for collaboration between practice and academic leaders in health care research. However, many problems can arise owing to differences between academic and clinical goals and timelines. In order for research to move forward it is important to name and address these issues early in a project. In this article we use an example of a participatory action research study of ethical practice in nursing to highlight some of the issues that are not (...) frequently discussed and we identify the impact of things not-named. Further, we offer our insights to others who wish to be partners in research between academic and practice settings. These findings have wide implications for ameliorating misunderstandings that may develop between nurse leaders in light of collaborative research, as well as for participatory action research.

This book explains the background and rationale of the German poet Johann Wolfgang von Goethe's notorious attack on Isaac Newton's classic theory of white light and colors. Though the merits of Goethe's color science, as advanced in his massive Zur Farbenlehre, have often been acknowledged, it has been almost unanimously proclaimed invalid as physics. How could Goethe have been so mistaken? In his book, Dennis Sepper shows that the condemnation of Goethe's attacks on Newton has been based on (...) erroneous assumptions about the history of Newton's theory and the methods and goals of Goethe's color science. By illuminating the historical background and the experimental, methodological, and philosophical aspects of Goethe's work, the author shows that his color theory is in an important sense genuinely physical and that, as simultaneously poet, scientist, historian, and philosopher, Goethe managed to anticipate important twentieth-century research not only in the history and philosophy of science, but even in color science itself.

This paper has the aim to provide a general view of the so called Jesuit Edition (hereafter JE) of Newton’s Philosophiae Naturalis Principia Mathematica (1739–1742). This edition was conceived to explain all Newton’s methods through an apparatus of notes and commentaries. Every Newton’s proposition is annotated. Because of this, the text – in four volumes – is one of the most important documents to understand Newton’s way of reasoning. This edition is well known, but systematic works (...) on it are still missing. We are going to fill this gap by means of a project exposed in the final remarks of this paper. In this paper we will: A) expound the way in which the notes and the additions to the JE were conceived by the commentators; B) provide some pieces of information about the commentators; C) summarize the most important of their notes; D) examine closely their notes as to a particularly important question: the so called "inverse problem of the central forces".

Newton’s Principia reconceptualizes rational mechanics and physics, and offers a novel unification of these heretofore distinct disciplines. In this paper, I argue for a reading of the Principia that insists on a strict distinction between the rational mechanics (in Books 1 and 2) and the physics (in Book 3), in which the Definitions and the Axioms/Laws play a surprising dual role that both distinguishes the rational mechanics from the physics and unifies them into a single project: a philosophical (...) mechanics.

Immanuel Kant's Metaphysical Foundations of Natural Science (1786) provides metaphysical foundations for the application of mathematics to empirically given nature. The application that Kant primarily has in mind is that achieved in Isaac Newton's Principia (1687). Thus, Kant's first chapter, the Phoronomy, concerns the mathematization of speed or velocity, and his fourth chapter, the Phenomenology, concerns the empirical application of the Newtonian notions of true or absolute space, time, and motion. This paper concentrates on Kant's second and third chapters—the (...) Dynamics and the Mechanics, respectively—and argues that they are best read as providing a transcendental explanation of the conditions for the possibility of applying the (mathematical) concept of quantity of matter to experience. Kant again has in mind the empirical measures of this quantity that Newton fashions in the Principia, and he aims to make clear, in particular, how Newton achieves a universal measure for all bodies whatsoever by projecting the static quantity of terrestrial weight into the heavens by means of the theory of universal gravitation. Kant is not attempting to prove a priori what Newton has established empirically but, rather, to clarify the character of Newton's mathematization by building Newton's empirical measures into the very concept of matter that is articulated in the Metaphysical Foundations.

Irena Štěpánová in this book explores Isaac Newton’s engagement with ancient wisdom, the Hexameral tradition, Hermeticism, theology, alchemy as well as natural philosophy. In so doing, she brings together the established historiography with her own new insights. Štěpánová’s study is more than a study of Newton’s thought, for it contains a good deal of background on ancient (e.g., Hermeticism) and early modern thought (e.g., the Cambridge Platonists). She also uses the interpretative lenses of several contemporary Newton and (...) non-Newton scholars in her work. Moreover, provides helpful summaries of Newton’s thought (e.g., his theology). Štěpánová has provided Newton scholarship a great service in this book, not only by making her Czech-language work available in English, but bringing to the English-language reader learning on Hebraic thought, philosophy of life and Hermeticism originally published in Czech.

Commentators attempting to understand the empirical method that Isaac Newton applies in his Mathematical Principles of Natural Philosophy (1687) are forced to grapple with the thorny issue of how to reconcile Newton's rejection of hypotheses with his appeal to absolute space. On the one hand, Newton claims that his experimental philosophy does not rely on claims that are assumed without empirical evidence, and on the other hand, Newton appeals to an absolute space that, by his own (...) characterization, does not make any impressions on our senses. Howard Stein (1967, 2002) has offered an insightful strategy for reconciling this apparent contradiction and suggested a way to enhance our understanding of Newton's 'empiricism' such that absolute space can be preserved as a legitimate part of Newton's experimental project. Recently, Andrew Janiak (2008) has posed a worthy challenge to Stein's empirical reading of Newton and directed our attention to the metaphysical commitments that underlie the experimental philosophy of Newton's Principia . Although Stein and Janiak disagree on the degree to which Newton's empiricism influences his natural philosophy, both agree and clearly show that an adequate treatment of Newton's empiricism cannot be divorced from consideration of Newton's views on God and God's relationship to nature.

Not a full treatment of Newton’s scientific method, this book discusses his optical research only in passing (342–43). Its subtitle better indicates its scope: it focuses narrowly on the argument for universal gravitation in Book III of the Principia. The philosophical project is to set out an “ideal of empirical success” realized by the argument. Newton claims his method is to “deduce” propositions “from phenomena.” On Harper’s interpretation Newton’s phenomena are patterns of data, which are used (...) to measure “parameters” by which the theory explains them. An example is Kepler’s Area Rule. Its fit to the data confirms the hypothesis that the force maintaining a body in orbit is directed toward the .. (shrink)

In this paper, I argue that major elements of Hume’s metaphysics and epistemology are not only directed at the inductive argument from design which seemed to follow from the success of Newton’s system, but also have far larger aims. They are directed against the authority of Newton’s natural philosophy; the claims of natural philosophy are constrained by philosophic considerations. Once one understands this, Hume’s high ambitions for a refashioned ‘true metaphysics’ or ‘first philosophy’, that is, Hume’s ‘Science of (...) Human Nature’, can be seen and evaluated in their proper light. Hume has three motives for his attack on Newton: his work is informed by and gives cover to superstitious beliefs; his project is not useful to the public; and its success generates a challenge to the independent authority of philosophy. This essay consists of five sections. First, I discuss Hume’s attitude toward Newton. Newton claims that natural philosophy should be the foundation for other sciences, while in the ‘Introduction’ to the Treatise Hume asserts the supremacy of the ‘science of man’. For Hume the human sciences can attain the high epistemic status of ‘proof’, while much of the physical sciences must do with lower forms of ‘probability’. Furthermore, Hume’s ‘rules by which to judge of causes and effects’ do not replicate Newton’s fourth Rule; this opens a gap between the ontologies and methodologies of Newton and Hume. Moreover, Hume’s account of causation is designed to undercut the reductionist bias of natural philosophy. According to Hume the parts of natural sciences that go beyond common life can be evaluated from the point of view of the science of man. I end with remarks on the philosophic origins and significance of Hume’s attack on Newton’s natural philosophy. I depart from two independent traditions of interpreting Hume. One tradition makes many references to Newton’s influence on Hume. On a more detailed level, proponents of this view may call attention to Hume’s ‘rules’, his ‘Experiments’ and ‘Anatomy’, his method of investigation, the application of Newtonian metaphors works (e.g., an ‘attraction’ in the ‘mental world’ on a par with that in the ‘natural world’ – the principles of association are, then, analogous to the laws of motion). Hume’s ‘science of man’ is said to be inspired by Newton’s science of nature. Hume wants his readers to feel that he is modeling his project on the successes of natural philosophy, exemplified by Newton. In the ‘Introduction’ to the Treatise and more explicitly in the opening pages of EHU, Hume suggests that his ‘science of man’ can parallel recent achievements in natural philosophy (especially planetary astronomy). Thus, my claim is not that Newton did not figure importantly in Hume’s philosophy, but, instead, that Hume’s project is in many respects more hostile to Newton’s achievements – as available to well-informed eighteenth-century readers – than many recent interpreters have realized. There is a different tradition that argues Hume simply did not understand Newton. Hume’s philosophy, thus, cannot do justice to Newtonian science. Hume’s lack of mathematical competence is said to be a barrier to his understanding of Newton’s mathematical natural philosophy. One finds this attitude behind the cranking of Bayesian machinery in John Earman’s attack on Hume’s treatment ‘Of Miracles’. However, this tradition begs the question; it takes the authority of ‘science’ for granted in Hume. Against this second tradition I argue that Hume did understand salient features of Newton’s methodology and position, although in ways often unappreciated by the first tradition mentioned above. For example, in his comments on Newton in the History of England, Hume discerns the (broad) outlines of Newton’s commitment to the method of analysis and synthesis (see Newton’s Opticks, Query 31) and how it differs from Boyle’s methodology. So, Hume has a subtle understanding of Newton’s methodology – even if one were to grant that he lacks appreciation of the role of mathematics in Newton’s natural philosophy. Leaving open the question whether Hume understood all the details of Newton’s system, Hume’s departures from Newton are best interpreted not as ‘ironic’, but as philosophically motivated. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:166 HUME'S INTEREST IN NEWTON AND SCIENCE Many writers have been forced to examine — in their treatments of Hume's knowledge of and acquaintance with scientific theories of his day — the related questions of Hume's knowledge of and acquaintance with Isaac Newton and of the nature and extent of Newtonian influences upon Hume's thinking. Most have concluded that — in some sense — Hume was acquainted (...) with and influenced by Newton's thought in particular and scientific thought in general. The genesis of this paper is the recent point of view put forward by Peter Jones which challenges the many permutations of this almost ritualistic standard line by removing Hume entirely from the Newtonian and the scientific scenes of thought. Jones argues that Hume knew less about Newton and science, and needed to know less about Newton and 2 science, than he believes is required by the above interpretation. Indeed, Jones argues that Hume's fundamental assumptions, which, according to Jones, derive ultimately from a form of Ciceronian humanism, drive a "wedge" between Newton's thought and that of 3 Hume. Even Hume's introductory remarks in the Treatise about his universal "science of man" are, for Jones, a declaration of independence from the materialistic trend (as Jones sees it) of Newtonian 4 science and not, as so many commentators have maintained — however tenuously or strongly evidence for linkage of Hume's project with Newtonian or scientific thought. Jones baldly argues that Hume totally lacked interest in science in general and in Newton and Newtonian science in particular. Following J. H. Burton's observation that Hume's work is surprisingly free from the "opinions" of contemporary scientists, 167 Jones states there is no evidence that Hume ever studied science at the University of Edinburgh or that he "pursued" scientific studies of any formal sort. Regarding Newtonian scientific thought, he emphasizes the paucity of specifically Newtonian scientific textbooks in the early eighteenth century 7 which might have been available for Hume to study and argues that nowhere in Hume's writings is there evidence of precise and detailed knowledge of Newton's science beyond what is available in Q Chamber's Cyclopaedia. Jones acknowledges that, in the Introduction to the Treatise, Hume utilizes a "general version" of Newton's "Regulae Philosophandi" from the beginning of Book III of Newton's Principia. Nevertheless, in Jones' view, Hume's fundamentally humanistic orientation separates him completely from g any Newtonian influence. Finally, according to Jones, Hume does not betray the least bit of knowledge of Newton's mathematics and its role in Newton's experimental methodology. On this evidence Jones grounds his central claim of Hume's "total lack of interest in contemporary science." What references there are to Newton and to science in Hume's works Jones finds "traceable to essentially literary predecessors such as Fontenelle or Montesquieu, or to standard works of theologians ] 2 or free-thinkers." The absence of clearly direct references to what Jones feels are scientific works results both from Hume's "total lack of interest in science" and from his commitment to a form of Ciceronian humanism which is "inimical" to what Jones finds to be the obvious materialistic tendencies of 13 science in the early modern period. Jones' account of the Ciceronian and French contexts of Hume's thought is excellent. But his claim that Hume had no interest whatsoever in science 168 is simply too strong and finally forces us to view science in Hume's day as equivalent to science in our own time, a manifestly anachronistic point of view. Throughout this paper, my argument will be conditioned by my view that Hume's interest in science cannot be separated from his epistemology or his religious scepticism. Hume's interest in science was precisely that of a man of letters of the eighteenth century vitally engaged in determining the proper use of scientific methodology in establishing the limits of the secular science of man once it has 14 been freed from the fetters of theology. Hume's interest in theological and epistemological issues inevitably gave rise to a strong interest on his part in the science of his day and in Newton's contributions... (shrink)

In §69.b of BT Heidegger attempts an existential genetic analysis of science, i.e. a phenomenology of the conceptual process of the constitution of the logical view of science (science seen as theory) starting from the Dasein. It attempts to do so by examining the special intentional-existential modification of (human) being-in-the-world, which is called the "mathematical projection of nature"; that is, by examining that special modification of our being, which places us in the state of experience that presents the world to (...) us as taught by, e.g., Galileo and Newton. The idea he puts forward is that modern mathematical physics and the corresponding experience of the real is the result of the mathematical projection of nature. Modern science, Heidegger says, stands out because it is mathematical. But we cannot get the answer to what this mathematicality consists in from mathematics, because mathematics is only a special manifestation of mathematicality. Here is what Heidegger means by "mathematicality" and, accordingly by "mathematical projection of nature." If one were to let two bodies of different weights fall simultaneously from the top of the tower of Pisa, Heidegger notes, both Galileo and an Aristotelian would see that the two bodies would reach the ground with as little time difference as possible, and not at exactly the same moment. Galileo, however, does something decisive: he claims that under conditions that would be impossible to ensure (if we removed absolutely all resistance to the motion of the bodies), the two bodies would reach the ground absolutely simultaneously. This is not something that he or the Aristotelian sees happening empirically. How, then, does Galileo insist so firmly on his position? How exactly does it happen that he has before him such a view of things? Heidegger's answer is that Galileo is mathematically projecting nature. In his Dialogues Galileo says "I conceive with my mind" (mente concipio) a body thrown to move on an infinitely extending horizontal plane, having eliminated from its path every possible obstacle. Finally, I argue that from the detailed interpretation of Heidegger's points of the mathematical and of the notion of mathematical projection of nature, we can arrive at the conclusions I had arrived at in my doctoral dissertation (2000) as regards the meaning and function of thought experiments in physics as seen from a Husserlian phenomenological point of view as intentional acts. In a nutshell, in thought experiments physics constitutes the special metaphysics (to use the Kantian term) of the primordial ontological region it investigates as well as attempts to make natural sense of the mathematical formalism in cases it proves necessary.

Newton characterizes the reasoning of Principia Mathematica as geometrical. He emulates classical geometry by displaying, in diagrams, the objects of his reasoning and comparisons between them. Examination of Newton’s unpublished texts shows that Newton conceives geometry as the science of measurement. On this view, all measurement ultimately involves the literal juxtaposition—the putting-together in space—of the item to be measured with a measure, whose dimensions serve as the standard of reference, so that all quantity is ultimately related to (...) spatial extension. I use this conception of Newton’s project to explain the organization and proofs of the first theorems of mechanics to appear in the Principia. The placementof Kepler’s rule of areas as the first proposition, and the manner in which Newton proves it, appear natural on the supposition that Newton seeks a measure, in the sense of a moveable spatial quantity, of time. I argue that Newton proceeds in this way so that his reasoning can have the ostensive certainty of geometry. (shrink)

In the Introduction to the Treatise Hume very enthusiastically announces his project to provide a secure and solid foundation for the sciences by grounding them on his science of man. And Hume indicates in the Abstract that he carries out this project in the Treatise. But most interpreters do not believe that Hume's project comes to fruition. In this paper, I offer a general reading of what I call Hume's ‘foundational project’ in the Treatise, but I (...) focus especially on Book 1. I argue that in Book 1 much of Hume's logic is put in the service of the other sciences, in particular, mathematics and natural philosophy. I concentrate on Hume's negative thesis that many of the ideas central to the sciences are ideas that we cannot form. For Hume, this negative thesis has implications for the sciences, as many of the texts I discuss make evident. I consider and criticize different proposals for understanding these implications: the Criterion of Meaning and the ‘Inconceivability Principle’. I introduce what I call Hume's ‘No Reason to Believe’ Principle, which I argue captures more adequately the link Hume envisions between his logic, in particular his examination of ideas, and the other sciences.

I discuss the three distinctions “absolute and relative”, “true and apparent”, and “mathematical and common”, for the specific case of time in Newton’s Principia. I argue that all three distinctions are needed for the project of the Principia and can be understood within the context of that project without appeal to Newton’s wider metaphysical and theological commitments. I argue that, within the context of the Principia, the three claims that time is absolute rather than relative, true (...) rather than apparent, and mathematical rather than common, are to be evaluated with respect to the needs of, and relative to the success of, the project of the Principia. I claim that Newton is thereby offering a new, and empirical, philosophy of time. (shrink)

It is often claimed (most recently by Michael Friedman) that Kant intended to justify Newton’s most fundamental claims expressed in the Principia, such as his laws of motion and the law of universal gravitation. In this article, I argue that the differences between Newton’s laws of motion and Kant’s laws of mechanics are not superficial or merely apparent. Rather, they reflect fundamental differences in their respective projects. This point can be seen especially clearly by considering the nature of (...) the various projects undertaken in Germany prior to Kant that discuss the laws of motion. Wolff and his followers qua metaphysicians were especially interested in providing nonempirical justifications of their laws of motion as well as an intelligible account of the fundamental properties of bodies in terms of substance, accident, and force. Maupertuis and Euler, despite often being seen as Newtonians, both drew on traditions other than Newton’s. Physics textbooks (by figures such as Erxleben, Karsten, ‘s Gravesande, and Musschenbroek) vary considerably in their aims, but in none of these cases is Newton’s main argument of the Principia presented. In light of the fact that these projects are distinct in significant ways from Newton’s project, the differences between Newton’s laws of motion and Kant’s laws of mechanics are most likely not merely apparent but reflect the fact that Kant, too, was pursuing a project fundamentally distinct from Newton’s.

In this expository article, a presentation is given of A.C. Crombie's life work in the history of science, Styles of Scientific Thinking in the European Tradition. The History of Argument and Explanation in the Mathematical and Biomedical Sciences and Arts (1994). The importance of this work for the philosophy of science and epistemology is comparable to the more renowned work of the 1960's and '70s, but threatens to be paradoxically overlooked because of its gigantic proportions. (No thorough study of the (...) book appeared up to now.) Crombie's earlier work started from a provocative version of continuism in the debate about the rise of modern science, ascribing the origin of the experimental tradition to methodological forebears in the thirteenth century (Grosseteste). Rather than revivifying this quarrel now, Crombie has offered us an emergentist picture of the rise of six subsequent major styles of science (using grand units of analysis) from the Greeks up to Darwin. These styles of thinking are superimposed upon another in that the definite breakthrough of each next style is consequent upon the recognition of the proper limits of the full grown previous style. In a first group, Crombie assembles three major styles for revealing regularities in individual phenomena, i.e. where the consideration of the collective to which the phenomenon belongs is not required for recognizing the regularity. Here we have (S1) the ancient style of postulating principles and entities according to a more or less apriorical evidence type or in axiomatic fashion; (S2) the experimental tradition from Alhazen up to Newton, and (S3) the style of hypothetical modelling, combining the former two in the vein of the rational artist as an (ultimately, also cognitive) engineer. In a second group the styles dealing with regularities discoverable only in a collectivity of phenomena are dealt with. Here we have the (S4) probabilistic style superimposed on the classical picture of rationality made up by the achieved styles in the first group. Then (S5) the taxonomic style is ready to be combined, finally, with S4, in order to discover the statistical economy of living nature in (S6), the 'genetic' style, culminating in Darwin's history of nature (which was to be expected). On the other hand, the latter style is traced back to the 16th and 17th century project of a history of languages and culture, of knowledge, and of mankind (which is a more surprising connection made by Crombie). In a final section some philosophical remarks are made regarding Crombie's project; mainly with respect to the larger perspective, in Crombie's terms, of an 'intellectual anthropology', or alternatively, in terms of a 'comparative epistemology'. Also the absence of a real analysis of the very concept of style is noted. (shrink)

The two books discussed here make important contributions to our understanding of the role of spacetime concepts in physical theories and how that understanding has changed during the evolution of physics. Both emphasize what can be called a ‘dynamical’ account, according to which geometric structures should be understood in terms of their roles in the laws governing matter and force. I explore how the books contribute to such a project; while generally sympathetic, I offer criticisms of some historical claims (...) concerning Newton, and argue that the dynamical account does not undercut ontological issues as the books claim. *Received January 2009; revised March 2009. †To contact the author, please write to: Department of Philosophy, 1423 University Hall MC 267, University of Illinois at Chicago, 601 S.

Por fim, procura-se mostrar como a querela entre Goethe e Newton é utilizada para defender as abstrações da física teórica dos ataques da assim denominada "física ariana" e, ao mesmo tempo, preservar o valor das considerações intuitivas de Goethe. This paper aims at exposing the Heisenberg's conference "The teachings of Goethe and Newton on colors in the light of modern physics", presented in 1941, whose translation is presented here. In the first place the paper analyzes the philosophical project of an ordination of the reality, developed by the physicist in the early 1940s and which is the basis for the discussion of the "Teachings of Goethe and Newton on colors". Secondly it exposes some philosophical implications of the quantum theory by emphasizing the point of view of the Copenhagen school. Finally, it shows how the dispute between Goethe and Newton is exploited to defend the abstractions of the theoretical physics against the attacks of the so called "German physicists" and, at the same time, to preserve the worth of the Goethe's intuitive analysis.

In lieu of an abstract, here is a brief excerpt of the content:Hume's Demarcation Project John Losee Demarcation, Ideas and Impressions David Hume sought to exclude certain concepts from the domain of empirically significant discourse. He was critical of talk about "substances" that bear qualities, "forces" that cause motions, "powers" that produce effects, "necessary connections" that determine sequences of events, "extension without matter" and "time independent of succession or change in any real existence."1 Hume proposed a demarcation ofideas, a (...) demarcation intended to exclude these notions. The demarcation project, if successful, would exclude Locke's notion of "substance" as well as Newton's notions of "Absolute Space" and "Absolute Time." Some interpreters have taken the demarcation project to be the centrepiece of Hume's philosophy. Others have seen it to be an incidental aspect of Hume's search for an empirical theory of human nature. I believe that David Pears was correct to insist that an acceptable account ofHume's philosophy include both the "destructive emphasis" and the "constructive emphasis."2 Hume's demarcation project is based on a presumed relation, or relations, between ideas and impressions. Hume made the following claims about "simple ideas," those ideas that "admit of no distinction nor separation" (T 2): 1)every simple idea in its first appearance is derived from some impression (Derivability Principle); 2)every simple idea in its first appearance copies some impression (Copy Principle); 3)every simple idea represents some impression (Representation Principle); 4)simple ideas and impressions resemble one another; 5)simple ideas correspond to impressions; 6)every simple idea is borroVd from some impression; Volume XVII Number 2 51 JOHN LOSEE 7)for every simple idea there is some temporally antecedent impression; and 8)impressions cause simple ideas. Primafacie, these claims are empirical claims about the genesis of our ideas. But within Hume's demarcation project these claims also function as criteria for membership in the class of simple ideas. Those ideas that satisfy the criteria constitute raw material from which complex ideas are formulated. Complex ideas are constructed from simple ideas. However, they are not copies of simple ideas. Aparticular complex idea is empirically significant provided that, 1) it is derivable from simple ideas; and 2) each of those simple ideas is derivable from impressions. The Case of the Missing Shade ofBlue Tensions arise within the demarcation project in part because Hume employs nonequivalent criteria—Derivability Principle, Copy Principle, Representation Principle—as if they were equivalent. The tension is acute in the case of the missing shade ofblue. The "missing shade" is an idea formulated by a person with extensive experience of colours, but no prior exposure to the shade in question. If this idea is a simple idea, then it is false that every simple idea copies some antecedent impression. Why did Hume cite—in both Treatise and Inquiry—this apparently destructive exception? Bernard Rollin has suggested that Hume may have cited the missing-shade-of-blue example as a rhetorical device toprotecthis dichotomous divisionofpropositionsinto those that are analytic a priori and those that are synthetic a posteriori (including the Derivabihty Principle).11 John O. Nelson agreed that Hume is concerned to emphasize the contingent, empirical status of the Derivabihty Principle.12 Nelson suggested that Hume sought tomake two points. The first pointis that an exception to the Derivability Principle is empirically possible. The second point is that thought-experiments like the missing-shade example are inadequate to establish conclusions about matters offact. To entertain such thought-experiments is to lapse into hypothetical speculation, a violation ofthe "experimental method ofreasoning."13 Perhaps it was for this reason that Hume dismissed the missing-shade case as unimportant. Hume urged that this case is "so particular and singular" thatit provides nogoodreason to abandon the Copy Principle (T 6). 52Hume Studies HUME'S DEMARCATION PROJECT D. M. Johnson has developed a hypothesis to explain why Hume believed that this exceptional case is not damaging to his demarcation project. According to Johnson, Hume may have believed that for a person to reconstruct a shade he never saw before, he must have developed an appropriately detailed Tiabitual spectrum'—i.e., an ordered set oftendencies and expectations concerning colours, built up as a result oflong experience with thingshavingthese colours—whichhe then employs...

From Clockwork to Crapshoot provides the perspective needed to understand contemporary developments in physics in relation to philosophical traditions as far ...

This paper explores the possibility of constructing a Cartesian space-time that can resolve the dilemma posed by a famous argument from Newton's early essay, De gravitatione. In particular, Huygens' concept of a center-of-mass reference frame is utilized in an attempt to reconcile Descartes' relationalist theory of space and motion with both the Cartesian analysis of bodily impact and conservation law for quantity of motion. After presenting a modern formulation of a Cartesian space-time employing Huygens' frames, a series of Newtonian (...) counter-replies are developed in order to estimate the viability of this relationalist project.

We apply the recently elaborated notions of ‘pragmatic truth’ and ‘pragmatic probability’ to the problem of the construction of a logic of inductive inference. It is argued that the system outlined here is able to overcome many of the objections usually levelled against such attempts. We claim, furthermore, that our view captures the essentially cumulative nature of science and allows us to explain why it is indeed reasonable to accept and believe in the conclusions reached by inductive inference.

An introduction to the model-theoretic approach in the philosophy of science is given and it is argued that this program is further enhanced by the introduction of partial structures. It is then shown that this leads to a natural and intuitive account of both "iconic" and mathematical models and of the role of the former in science itself.

Henry Harris noted that ‘the Baconian applied science of this world is the solid foundation upon which Hegel’s ladder of spiritual experience rests’. Understanding the philosophical character of Hegel’s Philosophy of Nature requires recognizing some basic legitimate philosophical issues embedded in the development of physics from Galileo to Newton (§2). These issues illuminate the character of Hegel’s analysis of philosophical issues regarding nature (§3) and the central aims and purposes of Hegel’s philosophy of nature (§4). Hegel recognized some key (...) weaknesses in Newton’s own mathematical treatment of planetary orbits which were only rectified when Johann Bernoulli recast Newtonian gravitational theory on the basis of mathematical analysis (calculus). So reconstructed, Newtonian physics provides sufficient grounds to ascribe gravitational force to matter (Enz. §§262, 269). Hegel incorporated this important point into his illuminating accounts of causal laws of nature and natural-scientific explanation. These points reveal how Hegel’s Science of Logic and Philosophy of Nature are interdependent works, integrated in part by Hegel’s critical, moderately holistic theory of semantic meaning and reference. Highlighting these features of Hegel’s Philosophy of Nature illuminates Hegel’s emergentist account of structural and functional organization of various kinds of natural phenomena. (shrink)
