En este artículo haré un análisis crítico del debate entre Larry Laudan y algunos defensores del Realismo Epistemológico Convergente. Según esta postura, las mejores teorías científicas exhiben éxito referencial y este rasgo prueba que tales teorías son, al menos, aproximadamente verdaderas. Para Laudan, es irrelevante considerar y tratar a las teorías científicas como si fueran verdaderas. Mostraré que los argumentos de Laudan en contra del Realismo Epistemológico Convergente son bastante plausibles, por lo que la defensa realista en contra de estos (...) argumentos parece no ser exitosa.

The dispute between scientific realism and anti-realism is one of the most exciting topics in the current general philosophy of science. In the debate, the anti-realists attack their opponents with two main arguments, the pessimistic induction and the underdetermination of theories by all possible data. The realists, on the other hand, defend their position through the famous no miracle argument, which seems to be their most important standpoint. In this paper, I will expose two reconstructions of this argument and will (...) make a criticism of it, so that the realistic approach will be seriously questioned . (shrink)

When it comes to name-calling, structural realists have heard pretty much all of it. Among the many insults, they have been called ‘empiricist anti-realists’ but also ‘traditional scientific realists’. Obviously the collapse accusations that motivate these two insults cannot both be true at the same time. The aim of this paper is to defend the epistemic variety of structural realism against the accusation of collapse to traditional scientific realism. In so doing, I turn the tables on traditional scientific realists by (...) presenting them with a dilemma. They can either opt for a construal of their view that permits epistemic access to non-structural features of unobservables but then face the daunting task of substantiating a claim that seems to have little hope of being true or they can drop the requirement of epistemic access to non-structural features but then face a collapse to epistemic structural realism. There is thus only one well supported way to be a realist. No wonder then that many traditional scientific realists have over the years expressed views that are strikingly similar to epistemic structural realism. It is high time to let these epistemic structural realists out of the closet. (shrink)

My talk will be guided by the idea that there are some familiar scientific practices that are epistemically significant. I will argue that we can test for the success of these practices empirically by examining cases in the history of science. Specifically, I will reconstruct one particular episode in the history of medicine – John Snow's reasoning concerning the infectiousness of cholera – and offer this case as a concrete example of the sort of empirical research that needs to be (...) done in order to discover what kinds of methodological practices and rules are actually of epistemic interest. Analysing this case, I will explain how it (and other cases like it) can help us resolve specific cases of underdetermination. After exploring some possible anti-realist responses to this argument, I will conclude that, while the anti-realist is (more or less legitimately) able to construct underdetermination scenarios on a case-by-case basis, he will likely have to abandon the strategy of using algorithms to do so, thus losing the much needed guarantee that there will always be rival cases of the required kind.

This paper discusses three shortcomings of the current state of the debate regarding historical evidence against scientific realism. Attending to these issues will direct the debate away from over-generalising wholesale arguments.

This paper presents Minimal Information Structural Realism. MISR claims that information is an ontologically and epistemologically objective physical entity1 and is perceived as, but not identical to, organization, form, or structure of nature. There is a relatively significant body of literature claiming that the essential, if not fundamental, element of nature is information. Authors differ on the precise description of information conceived this way. However, they do agree that it would be a forming element in nature, a factor responsible for (...) patterns observed in reality, apprehended through order, organization or structures. To express the fundamental ontological role of information in nature, a new kind of structural realism, or rather information structural realism, is needed. This paper is proposing exactly this in the form of minimal information structural realism. The basic claim of MISR is that information is a foundation of reality and it is perceived or apprehended through patterns or structures. This claim embodies basic intuitions regarding the role of information in nature. MISR is not associated with the structural realism SR of the ontic or epistemic kinds, and is only remotely related to the concept of information structural realism defined by Floridi. (shrink)

This paper shows that, under certain reasonable conditions, if the investigation of the behavior of a physical system is difficult, no scientific change can make it significantly easier. This impossibility result implies that complexity is then a necessary feature of models which truly represent the target system and of all models which are rich enough to catch its behavior and therefore that it is an inevitable element of any possible science in which this behavior is accounted for. I finally argue (...) that complexity can then be seen as representing an intrinsic feature of the system itself. (shrink)
