El descubrimiento de Neptuno fue uno de los mayores logros de la astronomía del siglo XIX. Armados con las herramientas del cálculo y con las observaciones del movimiento anómalo de Urano, Adams y Le Verrier determinaron, independientemente, la posible ubicación y masa de un hipotético planeta, lo que llevaría a su descubrimiento observacional. En este artículo me propongo demostrar que los métodos empleados por estos estaban influenciados por el método de análisis y síntesis de Newton. Mostraré, además, algunos principios epistemológicos (...) generales de la astronomía que se pueden extraer cuando consideramos estos métodos de investigación. (shrink)

REVIEW (1): "Jeff Kochan’s book offers both an original reading of Martin Heidegger’s early writings on science and a powerful defense of the sociology of scientific knowledge (SSK) research program. Science as Social Existence weaves together a compelling argument for the thesis that SSK and Heidegger’s existential phenomenology should be thought of as mutually supporting research programs." (Julian Kiverstein, in Isis) ---- REVIEW (2): "I cannot in the space of this review do justice to the richness and range of Kochan's (...) discussion [...]. There is a great deal in this foundational portion of Kochan's discussion that I find tremendously interesting and engaging [...]." (David R. Cerbone, in Studies in History and Philosophy of Science) ---- REVIEW (3): "Science as Social Existence will be of interest not only to Heidegger scholars but to anyone engaged in science and technology studies. [...] This is an informative and original book. Kochan should be praised for his clear, pleasant-to-read prose." (Michael Butler, in CHOICE). (shrink)

Historians of science have frequently sought to exclude modern scientific knowledge from their narratives. Part I of this paper, published in the previous issue, cautioned against seeing more than a literary preference at work here. In particular, it was argued—contra advocates of the Sociology of Scientific Knowledge —that a commitment to epistemological relativism should not be seen as having straightforward historiographical consequences. Part II considers further SSK-inspired attempts to entangle the currently fashionable historiography with particular positions in the philosophy of (...) science. None, I argue, is promising. David Bloor’s proposed alliance with scientific realism relies upon a mistaken view of contrastive explanation; Andrew Pickering’s appeal to instrumentalism is persuasive for particle physics but much less so for science as a whole; and Bruno Latour’s home-grown metaphysics is so bizarre that its compatibility with SSK is, if anything, a further blow to the latter’s plausibility.

ABSTRACT The argument of inference to the best explanation sets up that, given a phenomenon to be explained, several rival hypotheses race to provide an explanation and the hypothesis that explains the phenomenon better than its rival gives good reasons for the belief in its truth and, therefore, for the acceptance of such hypothesis. The argument supposes that these rival hypotheses share the same phenomenon to be explained. In this paper it is argued that, in a few scientific episodes, scientists (...) with different hypotheses, even if sharing the phenomenon to be explained, have different goals regarding the handling of the phenomenon; but then an issue arises as to the structure of the argument, since setting different aims to handle a phenomenon would result in an axiological targeting by the scientists, one not enclosed in the structure of the argument. In addition, axiological targeting can also show itself as something crucial for the issue of accepting a hypothesis, a state of affair not foreseen in the argument of inference to the best explanation again. The purpose of this paper is, by means of “research programs” principle by Imre Lakatos, and by means of a case study – the acceptance of the DNA double helix model – to sustain the concept that the axiological difference may prove to be crucial for the acceptance of one hypothesis rather than other rival hypotheses.

The discovery of Neptune was one of the greatest achievements of nineteenth-century astronomy. Using nothing but calculus and some observations of the Uranus’ anomalous motion, Adams and Le Verrier got to determine, independently, the possible place and mass of a hypothetical planet, which would produce its observational discovery. In this paper I will demonstrate that the methods used by these astronomers were influenced by Newton’s method of analysis and synthesis. Considering this, I will also expose, that some astronomy’s general epistemological (...) principles could be deduced when we consider these investigation methods. (shrink)

Alex Mesoudi’s book shows cultural evolution to be a mature field, which has already illuminated many instances of cultural change. Mesoudi’s presentation of the discipline nonetheless invites three objections. First, the culture concept it makes use of is not clearly defined; second, Mesoudi’s historical argument which looks back to the modern synthesis in order to predict an analogous synthesis in the social sciences is flawed; third, Mesoudi’s understanding of the positions held by leading figures within social science is shaky.

In this essay, I respond to Tim Lewens's proposal that realists and Strong Programme theorists can find common ground in reliabilism. I agree with Lewens, but point to difficulties in his argument. Chief among these is his assumption that reliabilism is incompatible with the Strong Programme's principle of symmetry. I argue that the two are, in fact, compatible, and that Lewens misses this fact because he wrongly supposes that reliabilism entails naturalism. The Strong Programme can fully accommodate a reliabilism which (...) has been freed from its inessential ties to naturalism. Unlike naturalistic epistemologists, the Strong Programme's sociologistic reliabilist insists that all scientific facts are the product of both natural and social causal phenomena. Anticipating objections, I draw on Wittgenstein's rule-following considerations to explain how the sociologistic reliabilist can account for standard intuitions about the objective elements of knowledge. I also explain how the Strong Programme theorist can distinguish between a belief's seeming reliable and its being reliable. (shrink)

This paper presents a survey of the literature on the problem of contingency in science. The survey is structured around three challenges faced by current attempts at understanding the conflict between “contingentist” and “inevitabilist” interpretations of scientific knowledge and practice. First, the challenge of definition: it proves hard to define the positions that are at stake in a way that is both conceptually rigorous and does justice to the plethora of views on the issue. Second, the challenge of distinction: some (...) features of the debate suggest that the contingency issue may not be sufficiently distinct from other philosophical debates to constitute a genuine, independent philosophical problem. And third, the challenge of decidability: it remains unclear whether and how the conflict could be settled on the basis of empirical evidence from the actual history of science. The paper argues that in order to make progress in the present debate, we need to distinguish more systematically between different expressions that claims about contingency and inevitability in science can take. To this end, it introduces a taxonomy of different contingency and inevitability claims. The taxonomy has the structure of an ordered quadruple. Each contingency and each inevitability claim contains an answer to the following four questions: (how) are alternatives to current science possible, what types of alternatives are we talking about, how should the alternatives be assessed, and how different are they from actual science?

Over the past decade or so a number of historians of science and historical geographers, alert to the situated nature of scientific knowledge production and reception and to the migratory patterns of science on the move, have called for more explicit treatment of the geographies of past scientific knowledge. Closely linked to work in the sociology of scientific knowledge and science studies and connected with a heightened interest in spatiality evident across the humanities and social sciences this 'spatial turn ' (...) has informed a wide-ranging body of work on the history of science. This discussion essay revisits some of the theoretical props supporting this turn to space and provides a number of worked examples from the history of the life sciences that demonstrate the different ways in which the spaces of science have been comprehended.

Debates about scientific realism are closely connected to almost everything else in the philosophy of science, for they concern the very nature of scientific knowledge. Scientific realism is a positive epistemic attitude toward the content of our best theories and models, recommending belief in both observable and unobservable aspects of the world described by the sciences. This epistemic attitude has important metaphysical and semantic dimensions, and these various commitments are contested by a number of rival epistemologies of science, known collectively (...) as forms of scientific antirealism. This article explains what scientific realism is, outlines its main variants, considers the most common arguments for and against the position, and contrasts it with its most important antirealist counterparts.

(i) Scientific realism is primarily a metaphysical doctrine about the existence and nature of the unobservables of science. (ii) There are good explanationist arguments for realism, most famously that from the success of science, provided abduction is allowed. Abduction seems to be on an equal footing, at least, with other ampliative methods of inference. (iii) We have no reason to believe a doctrine of empirical equivalence that would sustain the underdetermination argument against realism. (iv) The key to defending realism from (...) the pessimistic meta-induction is that we have greatly improved our capacity to understand the unobservable world over recent centuries. (shrink)

In the article “A Tension in the Strong Program: The Relation between the Rational and the Social,” I stated that David Bloor, citing the principle of symmetry, expresses that rational and irrational beliefs must be explained in the same way, that is, by causes of the same kind. On this wise, he rejects the methodology of traditional philosophers and historians of science as asymmetrical; since they explain evidence-based beliefs with epistemic reasons and unreasonable beliefs—e.g. beliefs based on indoctrination, propaganda, ideology, (...) and superstition—citing social factors. On the other hand, Bloor argues that the rational is made entirely of the social and, therefore, is itself a kind of social factor. But by admitting this maximum conception of social constructivism, Bloor can no longer consider the rational and the social as two separate identities and accuse the traditional view of asymmetry. However, Professor Finn Collin says that Bloor’s critique of the traditional model never commits him to the duality of the rational and the social. (shrink)
