 It is not uncommon to hear philosophers remark that the dialogue between the forms of realism and antirealism surveyed in this article shows every symptom of a perennial philosophical dispute. The issues contested range so broadly and elicit so many competing intuitions (about which, arguably, reasonable people may disagree) that some question whether a resolution is even possible. This prognosis of potentially irresolvable dialectical complexity is relevant to a number of further views in the philosophy of science, some of which arise as direct responses to it. For example, Fine ([1986b] 1996: chs. 7–8) argues that ultimately, neither realism nor antirealism is tenable, and recommends what he calls the “natural ontological attitude” (NOA) instead (see Rouse 1988, 1991 for detailed explorations of the view). NOA is intended to comprise a neutral, common core of realist and antirealist attitudes of acceptance of our best theories. The mistake that both parties make, Fine suggests, is to add further epistemological and metaphysical diagnoses to this shared position, such as pronouncements about which aspects of scientific ontology should be viewed as real, which are proper subjects of belief, and so on. Others contend that this sort of approach to scientific knowledge is non- or anti-philosophical, and defend philosophical engagement in debates about realism (Crasnow 2000, Mcarthur 2006). Musgrave (1989) argues that the view is either empty or collapses into realism.
