First, I answer the controversial question ’What is scientific realism?’ with extensive reference to the varied accounts of the position in the literature. Second, I provide an overview of the key developments in the debate concerning scientific realism over the past decade. Third, I provide a summary of the other contributions to this special issue.

Scientific realists argue that a good track record of multi-agent, and multiple method, validation of empirical claims is itself evidence that those claims, at least partially and approximately, reflect ways nature actually is independent of the ways we conceptualize it. Constructivists contend that successes in validating empirical claims only suffice to establish that our ways of modelling the world, our “constructions,” are useful and adequate for beings like us. This essay presents a thought experiment in which beings like us intersubjectively (...) validate claims about properties of particular things in nature under conditions in which those beings have profoundly different personal phenomenological experiences of those properties. I submit that the thought experiment scenario parallels our actual situation, and argue that this shows that successes in intersubjectively validating empirical claims are indeed enough to claim victory for the realist. More specifically, I champion a variation of realism that marries Ronald Giere’s brand of ‘perspectival realism’ with Philip Kitcher’s ‘real realism,’ and posits that causal relations between ourselves and properties instantiated in nature ground our references to the relevant properties even though our conceptions of them are perspective relative.

This essay extends my “invisible disagreement” argument for Color Realism (2017) to formulate an argument for Direct Realism. It uses a variation of an “inverted qualia” thought experiment to show that successes in intersubjectively validating empirical claims about colors is proof that a nuanced version of Direct Realism is correct.

A Metaphysics for Scientific Realism: Knowing the Unobservable has two primary aims. The first is to extract the most promising refinements of the idea of scientific realism to emerge in recent decades and assemble them into a maximally defensible realist position, semirealism. The second is to demonstrate that, contra antirealist scepticism to the contrary, key concepts typically invoked by realists in expounding their views can be given a coherent and unified explication. These concepts include notions of causation, laws of nature, (...) scientific kinds, and approximate truth, and consequently, the demonstration undertaken includes a metaphysical study of ideas more commonly employed unreflectively in epistemological assessments of the sciences. In this paper, I answer searching critiques of this project by Steven French, Michel Ghins, and Stathis Psillos. (shrink)
