Scientific realists contend that theory-conjunction presents a problem for empiricist conceptions of scientific knowledge and practice. Van Fraassen (1980) has offered a competing account of theory-conjunction which I argue fails to capture the mercenary character of epistemic dependence in science. Representative cases of theory-conjunction developed in the present paper show that mercenary reliance implies a "principle of epistemic symmetry" which only a realist can consistently accommodate. Finally, because the practice in question involves the conjunction of theories, a version of realism (...) more robust than the "entity realism" of Cartwright (1983, 1989) and Hacking (1983) is required to explain the success of theory-conjunction.

This paper aims to defend scientific realism against two versions of agnostic empiricism: a naive agnostic position, which suggests that the only rational option is to remain agnostic as to the truth of theoretical assertions, and van Fraassen's more sophisticated agnostic empiricism - which may be called "Hypercritical Empiricism". It first argues that given semantic realism, naive agnostic empiricism cannot be maintained: there is no relevant epistemic difference between theoretical assertions and observational ones. It then focuses on van Fraassen's more (...) sophisticated alternative to scientific realism and suggests that an attitude towards science which involves less than aiming at theoretical truth and believing in theories would be, in some concrete respect that empiricists should recognize, worse off than the recommended realist attitude. To this end, the paper develops the so-called conjunction argument into a diachronic argument for scientific realism. (shrink)

In “Well-Being and Pluralism” (2021), Polly Mitchell and Anna Alexandrova defend conceptual pluralism about well-being. Conceptual pluralism about well-being holds that there are multiple, irreducible concepts of well-being that are employed in different contexts, all equally legitimate as concepts of well-being. Moreover, “Conceptual pluralism about well-being entails that there is no single essence which characterises all and only instances of well-being.” (Mitchell and Alexandrova, 2021, p. 2422) Conceptual monism about well-being, on the other hand, holds, at a minimum, that there (...) is some essence that unites all legitimate uses of ‘well- being’. In this paper, I will argue that there is a version of conceptual monism about well-being, the network theory of well-being defended by Michael Bishop in his book The Good Life (2015), that can secure all of the benefits of Mitchell and Alexandrova’s conceptual pluralism, namely accommodating the wide range of uses of “well-being” in the sciences of well-being and in ordinary language. Mitchell and Alexandrova’s argument for pluralism depends on the inability of a monistic theory of well-being to account for this diversity of conceptions of well-being and the diversity of instruments used to measure well-being in the sciences. Bishop’s network theory, like Mitchell and Alexandrova’s pluralism, is designed to accommodate the scientific study of well-being. Because of this, it avoids the pitfalls of traditional, monistic conceptions of well-being despite its monistic credentials. I conclude with two novel arguments for the network theory. (shrink)
