Inspired by Bas van Fraassen’s Stance Empiricism, Anjan Chakravartty has developed a pluralistic account of what he calls epistemic stances towards scientific ontology. In this paper, I examine whether Chakravartty’s stance pluralism can exclude epistemic stances that licence pseudo-scientific practices like those found in Scientology. I argue that it cannot. Chakravartty’s stance pluralism is therefore prone to a form of debilitating relativism. Consequently, we need (1) some ground or constraint in relation to which epistemic stances can be ranked by degrees, (...) and (2) some way to demarcate science from pseudo-science so that we know what epistemic stances are about. Regarding (1), I argue that empirical detectability can serve as the ground in relation to which epistemic stances are ranked by degrees. Regarding (2), I argue for ranking sciences on a continuum according to established institutional criteria, rather than attempting to draw a strict demarcation. (shrink)

The commentators in this Special Issue on ‘Epistemology, ontology, and scientific realism’ raise substantial questions about, and objections to, central aspects of my own thinking about semirealism (a proposal for how best to formulate scientific realism), as well as the larger philosophical context in which debates about scientific realism unfold. This larger context concerns the nature of realism more generally and the epistemic stances that underlie our considered opinions of what the sciences are telling us about the ontology of the (...) world. In this paper, I consider my critics’ remarks, and endeavor to lay their criticisms to rest. (shrink)
