Abstract: In an attempt to avert Laudan’s pessimistic induction, Worrall and Psillos introduce a narrower version of scientific realism. According to this version, which can be referred to as “localized realism”, realists need not accept every component in a successful theory. They are supposed only to accept those components that led to the theory’s empirical success. Consequently, realists can avoid believing in dubious entities like the caloric and ether. This paper examines and critiques localized realism. It also scrutinizes Psillos’s historical study of the caloric theory of heat, which is intended to support localized realism.
Models, fiction and fictional models
Summary: The use of models to scientifically represent and study reality is widely recognized with good reasons as indispensable for the practice of science. Because models, unlikely pure verbal representation, are justifiably regarded as vehicles of representation that are not truth-apt, philosophical questions are natural raised concerning the nature of such vehicles and how they represent. A sizeable literature generated in recent years explores the possibility that ”scientific models are works of fiction”. Idealization and other similar strategies are often taken to be the means by which models are made. Arguing against this last claim, the thesis of this article is that most models in science are not fictional. The author argues against the idea that idealization is the means by which models of typically unobservable systems or mechanisms are made.
Pierre Duhem’s Good Sense as a Guide to Theory Choice
Abstract: This paper examines Duhem’s concept of good sense as an attempt to support a non rule-governed account of rationality in theory choice. Faced with the underdetermination of theory by evidence thesis and the continuity thesis, Duhem tried to account for the ability of scientists to choose theories that continuously grow to a natural classification. The author examines the concept of good sense and the problems that stem from it. The paper presents a recent attempt by David Stump to link good sense to virtue epistemology. It is argued that even though this approach can be useful for the better comprehension of the concept of good sense, there are some substantial differences between virtue epistemologists and Duhem. The athor proposes a possible way to interpret the concept of good sense, which overcomes the noted problems and fits better with Duhem’s views on scientific method and motivation in developing the concept of good sense.
Reasoning without the principle of sufficient reason
Abstract: According to Principles of Sufficient Reason, every truth (in some relevant group) has an explanation. One of the most popular defenses of Principles of Sufficient Reason has been the presupposition of reason defense, which takes endorsement of the defended PSR to play a crucial role in our theory selection. According to recent presentations of this defense, our method of theory selection often depends on the assumption that, if a given proposition is true, then it has an explanation, and this will only be justified if we think this holds for all propositions in the relevant group. In this paper the author argues that this argument fails even when restricted to contingent propositions, and even if we grant that there is no non-arbitrary way to divide true propositions that have explanations from those that lack them. The author gives an alternate explanation of what justifies our selecting theories on the basis of explanatory features: the crucial role is not played by an endorsement of a PSR, but rather by our belief that, prima facie, we should prefer theories that exemplify explanatory power to greater degrees than their rivals.
Dispositional Essentialism and the Laws of Nature
Summary: In this paper, Vetter looks at the argument for Dispositional Essentialism (DE) that has been put forward by A. Bird in his recent book Nature’s Metaphysics. Bird’s overall argument comes in two parts, one negative and one positive, which together are to establish DE as the best contender for a theory of properties and laws. Vetter argues that, even if all their particular steps go through, both parts of the argument have significant gaps. The negative argument, if successful, shows that at least one property has an essence, but not that any property has a dispositional essence. The positive argument, which aims to demonstrate the explanatory power of DE, fails to take account of the quantitative nature of the fundamental natural properties and laws. The paper finishes by suggesting a revision of DE’s doctrine that might solve the latter problem, but yet remains to be spelled out.
Evolution of Quine’s Thinking on the Thesis of Underdetermination and Scott Soames’s Accusation of Paradoxicality
Abstract: Scott Soames argues that interpreted in the light of Quine’s holistic verificationism, Quine’s thesis of underdetermination leads to a contradiction. It is contended here that if we pay proper attention to the evolution of Quine’s thinking on the subject, particularly his criterion of theory individuation, Quine’s thesis of underdetermination escapes Soames’ charge of paradoxicality.
Reductionist Philosophy of Technology: Stones Thrown from Inside a Glass House
Introduction: Mark Twain said that, for people whose only tool is a hammer, everything looks like a nail. In Thinking about Technology, Joe Pitt’s main tools appear to be those of the philosopher of science, so it is not surprising that he claims most problems of philosophy of technology are epistemic problems. As he puts it: ‘The strategy here is straightforward. Philosophers of science have examined in detail a number of concepts integral to our understanding of what makes science what it is. The bottom line is this: philosophical questions about technology are first and foremost questions about what we can know about a specific technology and its effects and in what that knowledge consists’ . Although Pitt points out important disanalogies between scientific and technological knowledge, nevertheless he emphasizes that philosophy of technology is primarily epistemology. Pitt has stipulatively defined ethical and political analyses of technology as not part of philosophy and philosophy of technology. While claiming to assess the foundations of philosophy of technology, he has adopted a reductionist approach to his subject matter, one that ignores or denigrates the majority of work in philosophy of technology. Does Pitt’s bold, reductionist move succeed?
History and philosophy of science reapproachment: Shared methodological framework
Abstract: The paper intends to identify some particular basic assumptions, approaches and means of proceeding, which are spontaneously shared by philosophers, sociologists and historians of science, besides the common interchange of meta-notions describing science. To this end, the specific subject matter, scope, meta-cognitive goals and methodological background of each of the three domains of science study is first outlined. Only two shared proceedings are further discussed in details: the objective attitude, called ‘playing a stranger’, and the historiographers’ involvement in demarcational problem resolution. A far-reaching prospect is finally suggested for philosophers and historiographers: methodological partnership, leading towards the elaboration of an impending integral metatheory of science.
The Hunt for Scientific Reason
Abstract: The thesis of underdetermination of theory by evidence has led to an opposition between realism and relationism in philosophy of science. Various forms of the thesis are examined, and it is concluded that it is true in at least a weak form that brings realism into doubt. Realists therefore need, among other things, a theory of degrees of confirmation to support rational theory choice. Recent such theories due to Glymour and Friedman are examined, and it is argued that their criterion of “unification” for good theories is better formulated in Bayesian terms. Bayesian confirmation does, however, have consequences that tell against realism. It is concluded that the prospects are dim for scientific realism as usually understood.
Potentiality: From Dispositions to Modality
Publisher’s Note: This book develops and defends dispositionalism about modality: the view that metaphysical modality is a matter of the dispositions that objects have. Dispositionalism is an attractive view for actualists about modality, and for anyone who embraces an anti-Humean metaphysics of powers. This book shows in detail how such a view is to be formulated, which challenges it faces, and how they may be met. The metaphysics of potentiality is examined in detail to show that the view meets the three main challenges for a metaphysics of modality: (1) Extensional correctness: providing the right truth-values for statements of possibility and necessity; (2) formal adequacy: providing the right logic for metaphysical modality; and (3) semantic utility: providing a semantics that links ordinary modal language to the metaphysics of modality.
