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.

Since the publication of Kitcher’s influential paper The Division of Cognitive Labor, some philosophers wondered about these two related issues: (1) which is the optimal distribution of cognitive efforts among rival methods within a scientific community?, and (2) whether and how can a community achieve such an optimal distribution? Though not committing to any specific answer to question (1), I claim that issue (2) does not depend exclusively on an invisible hand like mechanism, since both intra-scientific and extra-scientific institutions may (...) play a major role. Finally, I examine some practical difficulties of reallocating scientists from a method to another, which leads to stress the importance of well-planned training and recruitment. (shrink)

ABSTRACT This article addresses the prospects of applied naturalistic metaphysics from both a global and a local perspective. Adopting a broad Sellarsian approach, I look into whether metaphysics has a place and role in the overall scientific image and assess whether it has its own subject matter as a first- or second- order discipline. After outlining the general argument in section 1, section 2 examines our construal of science and metaphysics, drawing some considerations for restating the question about the viability (...) of naturalistic metaphysics. Sections 3 and 4, in turn, suggest two styles of naturalistic metaphysics that can be respectively applied on a global and on a local basis. I briefly outline their respective goals, problems and categories. I argue, in particular, that globally applied naturalistic metaphysics deals with issues about the fundamental structure of reality, whereas locally applied naturalistic metaphysics tackles riddles arising from the examination of specific unobservable posits in the frontiers of scientific ontology. Section 5 closes with concluding remarks that put metaphysics within the scientific image. (shrink)
