According to the argument from underconsideration, since theory evaluation is comparative, and since scientists do not have good reasons to believe that they are epistemically privileged, it is unlikely that our best theories are true. In this paper, I examine two formulations of this argument, one based on van Fraassen’s “bad lot” premise and another based on what Lipton called the “no-privile...

It is sometimes claimed that if moral realism is true, then rational and informed individuals would not disagree about morality. According to this line of thought, the moral realist is committed to an extremely substantive convergence thesis, one that might very well turn out to be false. Although this idea has been accepted by prominent moral realists as well as by antirealists, I argue that w...

The notion of literal construal divides anti-realists into two kinds: the kind who say that science aims to be true when construed non-literally; and kind van Fraassen belongs to, who say that while theories should be literally construed, they don’t have to be true. The first kind of anti-realist might claim e.g. that the theory of phlogiston and the modern theory of combustion say the same thi...

Scientific realists are committed to the claim that scientific discourse should be interpreted realistically, so that theoretical terms are understood as putatively referring expressions that have putative reference to empirical entities. In order to argue against realistic interpretation, I draw on an episode from the history of chemistry. One of the hypothetical entities of late 18th century ...

Randomized trials of complex public health interventions generally aim to identify what works, accrediting specific intervention 'products' as effective. This approach often fails to give sufficient consideration to how intervention components interact with each other and with local context. 'Realists' argue that trials misunderstand the scientific method, offer only a 'successionist' approach ...

I begin here in §1 with some prima facie linguistic difficulties had by two prominent metaethical accounts of the meaning of normative terms – basically the accounts implicit in realism and expressivism – when these are applied in a straightforward albeit naïve way to the word ‘ought’. In §2, I explain what I take to be the standard framework in theoretical semantics for accounting for the sema...

Scholars in international relations have long known that ideas matter in matters of international politics, yet theories of the discipline have failed to capture their impact either in the making of foreign policy or the nature of the international system. Recent reengagement with the insights of classical realists has pointed to the possibility of a neoclassical realist approach that can take ...

In this paper, I consider the pessimistic induction construed as a deductive argument (specifically, reductio ad absurdum) and as an inductive argument (specifically, inductive generalization). I argue that both formulations of the pessimistic induction are fallacious. I also consider another possible interpretation of the pessimistic induction, namely, as pointing to counterexamples to the sci...
