Abstract

In a recent volume of this journal Saatsi [Saatsi, J.. Reconsidering the Fresnel–Maxwell theory shift: How the realist can have her cake and EAT it too. Studies in History and Philosophy of Science, 36, 509–536.] suggests that we adopt an approach where we explain phenomena reductively, by properties that are described via their nomological roles. These properties are conceived of as higher-order multiply realisable properties. Such properties are however not causally efficacious independent of their causal basis. Therefore Saatsi has left it open what kind of explanatory work these properties could possibly do.Keywords: Realism; Multi realisability; Structuralism; Semirealism; Eclectic realism; Higher-order propertiess.
