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.

The standard reliabilist line on defeat is open to counterexamples regarding its necessity and sufficiency. In this paper, I present three problems for the standard reliabilist line from the recent literature on defeat before arguing that reliabilists can solve those problems by adopting an account of justification that ties defeat to the evidence possessed by the relevant agent. In doing so, I show that there is a conception of having evidence that reliabilists can adopt without giving up on the core commitments of their research program, namely the reduction of epistemic facts and having a psychologically realistic account of justification. My account of defeat draws on the account of propositional justification, transglobal evidentialism, defended by David Henderson, Terry Horgan, and Matjaž Potrč.
