Philosophical discussions of biological classification have failed to recognise the central role of homology in the classification of biological parts and processes. One reason for this is a misunderstanding of the relationship between judgments of homology and the core explanatory theories of biology. The textbook characterisation of homology as identity by descent is commonly regarded as a definition. I suggest instead that it is one of several attempts to explain the phenomena of homology. Twenty years ago the ‘new experimentalist’ movement (...) in philosophy of science drew attention to the fact that many experimental phenomena have a ‘life of their own’: the conviction that they are real is not dependent on the theories used to characterise and explain them. I suggest that something similar can be true of descriptive phenomena, and that many homologies are phenomena of this kind. As a result the descriptive biology of form and function has a life of its own—a degree of epistemological independence from the theories that explain form and function. I also suggest that the two major ‘homology concepts’ in contemporary biology, usually seen as two competing definitions, are in reality complementary elements of the biological explanation of homology.

This paper discusses an argument for scientific realism put forward by Anthony Quinton in The Nature of Things. The argument – here called the controlled continuity argument – seems to have received no attention in the literature, apparently because it may easily be mistaken for a better-known argument, Grover Maxwell’s “argument from the continuum”. It is argued here that, in point of fact, the two are quite distinct and that Quinton’s argument has several advantages over Maxwell’s. The controlled continuity argument (...) is also compared to Ian Hacking’s “argument from coincidence”. It is pointed out that both arguments are to a large extent independent from considerations about high-level scientific theories, and that both are abductive arguments at the core. But these similarities do not dilute an important difference related to the fact that Quinton’s argument cleverly seeks to anchor belief in unobservable entities in realism about ordinary objects, which is a position shared by most contemporary scientific anti-realists.

Van Fraassen does not argue that everyone should be a constructive empiricist. He claims only that constructive empiricism (CE) is a coherent post-positivist alternative to realism, notwithstanding the realist's charge that CE is arbitrary and irrational. He does argue, however, that the empiricist is obliged to limit belief as CE prescribes. Criticism of CE has been largely directed at van Fraassen's claim that CE is a coherent option. Far less attention has been directed at his claim that empiricists should be (...) constructive empiricists. I consider his various attempts to support this claim, conclude that they are unsuccessful, and suggest that the empiricist who repudiates CE does not thereby abandon contemporary empiricism itself.

Credibility in a scientific community (sensu Shapin) is a vicarious selector (sensu Campbell) for the reliability of reports by individual scientists or institutions. Similarly, images from a microscope (sensu Hacking) are vicarious selectors for studying specimens. Working at different levels, the process of indirect reasoning and checking indicates a unity to experimentalist and sociological perspectives, along with a resonance of strategies for assessing reliability. The perspective sketched here can open dialogue between philosophical and sociological interpretations of science and resolves at (...) least one tension regarding the "primary" factors by which scientists evaluate claims.

This paper defends a Hackingian approach to the scientific realism debate by arguing against mainstream realists’ and antirealists’ common claim that no experimental arguments for the reality of posited entities can be theory-independent. Opposing this claim, I argue that some experimental arguments can warrant belief in the existence of entities without depending on the truth of the theories that posit the entities and describe their properties and the theories that explain the interactions between the entities and the experimental devices. To (...) achieve this goal, I investigate Hacking’s case of electron spraying, the famous experiment of positioning atoms by means of a scanning tunnelling microscope, and some novel experiments that use Ashkin’s optical tweezers. By introducing the distinction between theoretical properties and ontic properties, I argue that we can build up some theory-independent criteria of reality on the basis of ontic properties. Manipulability is an ontic property and the manipulation criterion is thus a theory-independent one, which should be reexamined and used for those experimental cases along a local approach to the realism debate. Resisting the mainstream realists’ and antirealists’ objections, I contend that some experiments using optical tweezers can warrant belief in the existence of the experimented entities without depending on theories.

Martin Kusch has recently defended Bas van Fraassen’s controversial view on microscopes, according to which these devices are not ‘windows on an invisible world’, but rather ‘image generators’. The two authors also claim that, since in a microscopic detection it is not possible to empirically investigate the geometrical relations between all the elements involved, one is entitled to maintain an agnostic stance about the reality of the entity allegedly represented by the produced image. In this paper I argue that, contrary (...) to what Kusch maintains, this might not be a neutral way to render scientific evidence. Moreover, a constructive empiricist can support a realist interpretation of microscopic images. In fact, constructive empiricism and van Fraassen’s own anti-realism do not necessarily amount to the same thing. (shrink)

Evoluția testelor gravitaționale dintr-o perspectivă epistemologică încadrată în conceputul de reconstrucție rațională al lui Imre Lakatos, pe baza metodologiei acestuia a programelor de cercetare. Perioada evaluată este foarte vastă, începând cu filosofia naturală a lui Newton și până la teoriile gravitației cuantice din zilele noastre. Pentru a explica mai rațional evoluția complexă a conceptului de gravitație din ultimul secol, propun o extindere naturală a metodologiei programelor de cercetare pe care o folosesc apoi pe parcursul lucrării. Consider că această abordare oferă (...) o nouă perspectivă asupra modului în care au evaluat în timp conceptul de gravitație și metodele de testare a fiecărei teorii a gravitației, prin observații și experimente. Argumentez, pe baza metodologiei programelor de cercetare și a studiilor oamenilor de știință și filosofilor, că actualele teorii ale gravitației cuantice sunt degenerative, datorită lipsei dovezilor experimentale pe o perioadă îndelungată de timp și a auto-imunizării împotriva posibilității falsificării. Mai mult, în prezent este în curs de dezvoltare un curent metodologic care atribuie un rol secundar, neimportant, verificărilor prin observații și/sau experimente. Din această cauză, nu va fi posibilă o teorie completă a gravitației cuantice în forma actuală care să includă la limită relativitatea generală, întrucât teoriile fizice au fost dintotdeauna ajustate, în decursul evoluției lor, pe baza testelor observaționale sau experimentale, și verificate prin predicțiile făcute. De asemenea, contrar unei opinii răspândite și a unor programe active actuale privind unificarea tuturor forțelor fundamentale ale fizicii într-o singură teorie finală, pe baza teoriei corzilor, argumentez că este puțin probabil în general să se realizeze această unificare, și nu este posibil oricum ca unificarea să se elaboreze pe baza teoriilor actuale ale gravitației cuantice, inclusiv prin teoria corzilor. În plus, susțin punctele de vedere ale unor oameni de știință și filosofi că în prezent se consumă mult prea multe resurse pe ideea dezvoltării teoriilor gravitației cuantice, și în special teoria corzilor, care să includă relativitatea generală și să unifice gravitația cu celelalte forțe, în condițiile în care știința nu impune astfel de programe de cercetare. -/- DOI: 10.13140/RG.2.2.14582.75842 .

Although scientific realism is the default position in the life sciences, philosophical accounts of realism are geared towards physics and run into trouble when applied to fields such as biology or neuroscience. In this paper, I formulate a new robustness-based version of entity realism, and show that it provides a plausible account of realism for the life sciences that is also continuous with scientific practice. It is based on the idea that if there are several independent ways of measuring, detecting (...) or deriving something, then we are justified in believing that it is real. I also consider several possible objections to robustness-based entity realism, discuss its relationship to ontic structural realism, and show how it has the potential to provide a novel response to the pessimistic induction argument.

Agreement between "independent" measurements of a theoretically posited quantity is intuitively compelling evidence that a theory is, loosely speaking, on the right track. But exactly what conclusion is warranted by such agreement? I propose a new account of the phenomenon's epistemic significance within the framework of Bayesian epistemology. I contrast my proposal with the standard Bayesian treatment, which lumps the phenomenon under the heading of "evidential diversity".

Au cours des dernières décennies, la philosophie des sciences est devenue la philosophie des sciences particulières. En conséquence, certaines des questions majeures de la philosophie des sciences sont adressées à la recherche en nanosciences et technologie. C’est le cas notamment des questions concernant la nature de la connaissance, le rôle de la théorie, les pratiques expérimentales et observationnelles. Ces questions habituelles suscitent des réponses inattendues, suggérant que la nanotechnoscience est un exemple non pas d’une science mais d’une technoscience.

Wesley Salmon defends an ontic realism that distinguishes explanatory from descriptive knowledge. Explanatory knowledge makes appeals to (unobservable) theoretical acausal mechanisms. Salmon presents an argument designed both to legitimize attributing truth values to theoretical claims and to justify treating theoretical claims as descriptions. The argument succeeds but only at the price of calling the distinction between explanation and description into question. Even if Salmon's attempts to distinguish causal mechanisms from other mechanisms are successful, the assumed centrality of the appeal to (...) such mechanisms in providing scientific explanations is left open by Salmon's account.

The aim of this paper is to note the convergence between two critical realist philosophies of science, namely, that of Roy Bhaskar and Bernard Lonergan with regard to the intelligibility of experimental activity. Bhaskar very explicitly argues that ‘differentiation implies stratification.’ The idea is that because the situations produced in laboratories are special instances of closure the significance of experimental activity is that it brings about regularities with a view to understanding scientific laws at a deeper level. This is to (...) say, when experiment is properly understood, the weaknesses of empiricism are exposed. Although he is not as explicit, Lonergan also has recourse to this argument. The parallels between Bhaskar and Lonergan are not surprising given the Aristotelian heritage that is manifest in their common concern for a realist ontology. Nevertheless, some differences between the two emerge, for example, in Lonergan's concern with the development of statistical science, and as well, a firm commitment to substance. Some attention to the significance of experimental activity for the debate surrounding realism is explored; it is suggested that Lonergan has something to offer in the subsequent conversation associated with Maxwell, van Fraassen, Hacking and Cartwright.

This paper takes part in the methodological debate concerning the nature and the justification of hypotheses about computational systems in software engineering by providing an epistemological analysis of Software Testing, the practice of observing the programs’ executions to examine whether they fulfil software requirements. Property specifications articulating such requirements are shown to involve falsifiable hypotheses about software systems that are evaluated by means of tests which are likely to falsify those hypotheses. Software Reliability metrics, used to measure the growth of (...) probability that given failures will occur at specified times as new executions are observed, is shown to involve a Bayesian confirmation of falsifiable hypotheses on programs. Coverage criteria, used to select those input values with which the system under test is to be launched, are understood as theory-laden principles guiding software tests, here compared to scientific experiments. Redundant computations, fault seeding models and formal methods used in software engineering to evaluate test results are taken to be instantiations of some epistemological strategies used in scientific experiments to distinguish between valid and non-valid experimental outcomes. The final part of the paper explores the problem, advanced in the context of the philosophy of technology, of defining the epistemological status of software engineering by conceiving it as a scientifically attested technology.

Ever since Hilary Putnam claimed that a realist philosophy is “the only philosophy that doesn’t make the success of science a miracle,” explanations for the success of science have proliferated in the philosophical literature (Putnam 1975, p. 73). Realists argue that the success of science, as exhibited by our ability to accurately predict and explain a wide range of phenomena, indicates that our theories have identified some of the underlying causal structures of the world (e.g., Boyd 1985, Ellis 1985, McMullin (...) 1984, Salmon 1984). Nonrealists counter that success cannot provide a warrant for belief in the truth of scientific theories because there have been successful theories in the past that are now believed to be false (Laudan 1981b). Instead, they offer a naturalized account whereby our theories are designed to be successful predictors and only those which fulfill this goal survive (Laudan 1987, van Fraassen, 1980). (shrink)

Kendall Walton argues that photographs are transparent; we literally see the things depicted in them, not just the depictions. This intriguing claim has endured numerous criticisms from those I call the ‘egocentrists’, according to whom seeing—literal seeing—requires the conveyance of egocentric information; to count as seeing something, a visual experience of that thing must impart some information, however spare, about its position relative to the viewer. Since photographs fail to convey such information, the egocentrists claim, Walton’s transparency thesis fails. This (...) paper considers several ways this egocentric condition on seeing has been developed and shows that none of them is persuasive. Seeing, I argue, does not require the conveyance of egocentric information. As such, and barring other problems, Walton’s transparency thesis stands. The paper closes with a speculative discussion of the kinds of empirical and action-guiding considerations that motivate egocentrism. (shrink)

The use of multiple means of determination to “triangulate” on the existence and character of a common phenomenon, object, or result has had a long tradition in science but has seldom been a matter of primary focus. As with many traditions, it is traceable to Aristotle, who valued having multiple explanations of a phenomenon, and it may also be involved in his distinction between special objects of sense and common sensibles. It is implicit though not emphasized in the distinction between (...) primary and secondary qualities from Galileo onward. It is arguably one of several conceptions involved in Whewell’s method of the “consilience of inductions” (Laudan 1971) and is to be found in several places in Peirce. (From M. Brewer and B.

There is good reason to believe that, if it can be decided at all, the realism debate must be decided on a posteriori grounds. But at least prima facie the prospects for an a posteriori resolution of the debate seem bleak, given that realists and antirealists disagree over two of the most fundamental questions pertaining to any kind of empirical research, to wit, what the range of accessible evidence is and what the methodological status of explanatory considerations is. The present (...) paper aims to show that, while the difficulties that face an empirical approach to the realism debate are not to be discounted, they are not insurmountable either. Specifically, it presents a broadly Bayesian strategy for resolving the debate that is capable of solving those difficulties. The strategy crucially involves answers to the aforementioned questions that diverge from both the standard realist and the standard antirealist answers, but that should appear more natural and plausible than those to realists and antirealists alike.

Ludwik Fleck is a pioneer of the contemporary social constructionist trend in scientific theory, where his central concept of thinking style has become standard fare. Yet the concept is too often misunderstood and simplified with serious consequences not only for Fleck studies.

Let us call ‘veridicalism’ the view that perceptual beliefs and observational reports are largely truthful. This paper aims to make a case for veridicalism by, among other things, examining in detail and ultimately deflating in import what many consider to be the view’s greatest threat, the so-called ‘theory-ladenness’ of perception and/or observation. In what follows, it is argued that to the extent that theoretical factors influence the formation of perceptual beliefs and observational reports, as theory-ladenness demands, that influence is typically (...) not detrimental to their veridicality or at least not irreversibly so. Central to the defence of veridicalism are two principles: that of internal similarities and that of internal dissimilarities. (shrink)

Setting out to understand Frege, the scholar confronts a roadblock at the outset: We just have little to go on. Much of the unpublished work and correspondence is lost, probably forever.

According to a popular strategy amongst economists and philosophers, in order to solve the problem of interpersonal utility comparisons, we have to look at how ordinary people make such comparisons in everyday life. The most recent attempt to develop this strategy has been put forward by Goldman in his “Simulation and Interpersonal Utility” (Ethics 4:709–726, 1995). Goldman claims, first, that ordinary people make interpersonal comparisons by simulation and, second, that simulation is reliable for making interpersonal comparisons. In this paper, I (...) focus on Goldman’s latter claim. After updating Goldman’s account of how ordinary people make interpersonal comparisons in the light of Goldman’s newest formulation of his simulation theory of mental ascription (Goldman, Simulating Minds. Oxford University Press, Oxford, 2006), I develop and assess Goldman’s arguments in favour of the reliability of simulation for interpersonal comparisons. I argue that, under certain conditions, there may be room for a scientifically acceptable solution to the problem of interpersonal utility comparisons. (shrink)

La cuestión de la subjetividad en el campo de la comunicación. Una reflexión epistemológica.

RESUMO Neste artigo pretendo expor sinteticamente os problemas levantados contra uma das formas de realismo científico conhecida como realismo experimental, além de propor uma formulação mais aceitável do mesmo, resistente a tais críticas. Os problemas alegados pelos oponentes do realismo experimental variam desde a acusação de inadequação em relação à prática da comunidade científica, até a inconsistência ao admitir entidades e propriedades postuladas teoricamente recusando, entretanto, as teorias em que tais entidades e propriedades aparecem. Some-se a essas críticas a de (...) que o próprio critério do realismo de entidades seria implausível, seja porque falha na produção de crenças verdadeiras ou porque não fornece garantias melhores do que outras formas de realismo científico. Argumentarei que, adotando o realismo experimental exclusivamente como um critério epistêmico e aplicando tal critério às propriedades é possível contornar as críticas, reabilitando uma proposta realista que muitos consideravam já descartada. ABSTRACT In this paper, I will expose briefly the problems raised against one kind of scientific realism known by experimental realism and also will propose an acceptable formulation of that realism, resistant to those criticisms. The problems claimed by the experimental realism’s opponents range from the accusation of inadequacy with the scientific community’s practice to the claim that the admission of entities and proprieties without accepting the theories in which those proprieties and entities are supposed is incoherent. Besides, there is another criticism which states that the entities realism’s criterion is implausible, either because it fails to produce true beliefs or because there is no better warranty in adopting it than other kinds of scientific realism. I will argue that adopting experimental realism exclusively as an epistemic criterion and applying that criterion to proprieties it is possible to escape the criticisms, rehabilitating a realist propose that many people though already discarded.

In this chapter I investigate the prospects of integrated history and philosophy of science, by examining how philosophical issues raised by “hidden entities”, entities that are not accessible to unmediated observation, can enrich the historical investigation of their careers. Conversely, I suggest that the history of those entities has important lessons to teach to the philosophy of science. Hidden entities have played a crucial role in the development of the natural sciences. Despite their centrality to past scientific practice, however, several (...) of them (e.g., phlogiston, caloric, and the ether) turned out to be fictitious. For this reason, they have figured prominently in recent debates on scientific realism. The issues I explore in this paper are entangled with those debates. I argue that our understanding of hidden entities and their role in experimental practice can be enhanced by adopting an integrated historical-cum-philosophical approach. On the one hand, philosophical reflection on the reality of those entities has a lot to gain by examining historically how they were ntroduced and investigated. On the other hand, the historical reconstruction of the careers of those entities may profit from philosophical reflection on their existence. (shrink)

Multiple determination is the epistemic strategy of establishing the same result by means of multiple, independent procedures. It is an important strategy praised by both philosophers of science and practicing scientists. Despite the heavy appeal to multiple determination, little analysis has been provided regarding the specific grounds upon which its epistemic virtues rest. This article distinguishes between the various dimensions of multiple determination and shows how they can be used to evaluate the epistemic force of the strategy in particular cases. (...) Distinguishing between the various dimensions helps to resolve the disagreements regarding the relevance and epistemic import of multiple determination for scientific research. It also suggests a fruitful mode of interaction between the philosophy of science and (historical) accounts of scientific practice. (shrink)

In my dissertation I define historical disciplines as disciplines that aim to give a historical interpretation of the evidence.

Bas van Fraassen’s recent book Scientific Representation: Paradoxes of Perspective modifies and refines the “constructive empiricism” of The Scientific Image in a number of ways. This paper investigates the changes concerning one of the most controversial aspects of the overall position, that is, van Fraassen’s agnosticism concerning the veridicality of microscopic observation. The paper tries to make plausible that the new formulation of this agnosticism is an advance over the older rendering. The central part of this investigation is an attempt (...) to answer Marc Alspector-Kelly’s 2004-criticism of an early version of van Fraassen’s new position. Alspector-Kelly’s contribution it is to date the most extensive attack on van Fraassen’s twenty-first-century work on the topic of microscopic observation. One of the central ideas emerging from the present discussion is a link between the debate over the veridicality of microscopic observation and the issue of the theory-ladenness of experience.

In many scientific fields, today’s practices of empirical enquiry rely heavily on the production of images that display the investigated phenomena. And while scientific images of phenomena have been important for a long time, what is striking now is that scientists have found ways to visualize such widely different types of phenomena. In the past twenty or thirty years, we have become accustomed to seeing images of galaxies, of cells, of the human brain but also of blood flow or of (...) turbulent fluids. This success in making images relies first on the set of imaging devices that have flourished in the twentieth century, instruments such as radio-telescopes, electronic microscopes, MRI and many more.

Inference to the Best Explanation has become the subject of a livelydebate in the philosophy of science. Scientific realists maintain, while scientificantirealists deny, that it is a compelling rule of inference. It seems that anyattempt to settle this debate empirically must beg the question against theantirealist. The present paper argues that this impression is misleading. A methodis described that, by combining Glymour's theory of bootstrapping and Hacking'sarguments from microscopy, allows us to test IBE without begging any antirealistissues.

Carnap's mature philosophy of science is an attempt to dissolve the scientific realism debate altogether as a philosophical pseudo-question. His argument depends upon a logico-semantic thesis regarding the structure of a scientific theory, and more importantly, a meta-ontological thesis regarding the explication of existence claims. The latter commits Carnap to a distinction between the analytic and the synthetic, which was allegedly refuted by Quine. The contemporary philosophy of science has therefore sought to distance itself from logico-semantic considerations, and has pursued (...) the scientific realism debate as an essentially epistemological thesis. I show however that one of the most prominent positions in this recent debate—van Fraassen's constructive empiricism—not only ends up in very close proximity to Carnap's attempted dissolution, but even provides the resources for extending and refining his programme. Rather than a historical footnote, Carnap's mature philosophy of science offers a live-option in the current debate. (shrink)

Bachelard regarded the scientific changes that took place in the early twentieth century as the beginning of a new era, not only for science, but also for philosophy. For him, the theory of relativity and quantum mechanics had shown that a new philosophical ontology and a new epistemology were required. I show that the type of philosophy with which he was more closely associated, in particular that of Léon Brunschvicg, offered to him a crucial starting point. Brunschvicg never considered scientific (...) objects as independent of the mind, and as a consequence questions such as the existence of particles independently of the mind, theory or apparatus, were absent from his philosophy, which was rather aimed at analyzing the mind critically, and above all historically. Bachelard accepted the fundamental ideas of Brunschvicg’s philosophy; however, his own reading of contemporary science enabled him to go beyond it, as shown by his emphasis on the social production of knowledge, and by his removal of the distinction between ideas and technologically produced objects of knowledge. For him, modern science teaches philosophy that knowledge is not a phenomenology but rather a ‘phenomenotechnique’. I argue that Bachelard’s view that philosophy ‘should follow science’ stems from moral considerations.Keywords: Gaston Bachelard; Léon Brunschvicg; Phenomenotechnique; Chosisme; Theory of relativity; Quantum mechanics.

The article analyses the role of time in the visual culture of two phases in embryological research: at the end of the nineteenth century, and in the years around 2000. The first case study involves microscopical cytology, the second reproductive genetics. In the 1870s we observe the first of a series of abstractions in research methodology on conception and development, moving from a method propagated as the observation of the “real” living object to the production of stained and fixated objects (...) that are then aligned in temporal order. This process of abstraction ultimately fosters a dissociation between space and time in the research phenomenon, which after 2000 is problematized and explicitly tackled in embryology. Mass data computing made it possible partially to re-include temporal complexity in reproductive genetics in certain, though not all, fields of reproductive genetics. Here research question, instrument and modelling interact in ways that produce very different temporal relationships. Specifically, this article suggests that the different techniques in the late nineteenth century and around 2000 were employed in order to align the time of the researcher with that of the phenomenon and to economize the researcher’s work in interaction with the research material’s own temporal challenges.

This discussion paper proposes that a meaningful distinction between science and technoscience can be found at the level of the objects of research. Both notions intermingle in the attitudes, intentions, programs and projects of researchers and research institutions—that is, on the side of the subjects of research. But the difference between science and technoscience becomes more explicit when research results are presented in particular settings and when the objects of research are exhibited for the specific interest they hold. When an (...) experiment is presented as scientific evidence which confirms or disconfirms a hypothesis, this agrees with traditional conceptions of science. When organic molecules are presented for their capacity to serve individually as electric wires that carry surprisingly large currents, this would be a hallmark of technoscience. Accordingly, we propose research on the ontology of research objects. The focus on the character and significance of research objects makes this a specifically philosophical project. (shrink)

Notre visée, dans cet article, consiste à souligner que la prise en compte d’une stratégie couramment employée par les chercheurs au sein des sciences expérimentales, l’interinstrumentalité, permet de réduire l’impact des facteurs micro- et macrosociaux, privilégiés par les tenants du programme relativiste empirique de Harry Collins, lorsqu’il s’agit d’expliquer la clôture des débats sur la valeur à conférer aux données collectées.
