Between Abduction and the Deep Blue Sea

Stathis Psillos and James Ladyman et al. have recently joined battle over Bas van Fraassen's account of abduction and inference to the best explana-tion (IBE), and while van Fraassen makes many interesting criticisms, Psillos has had the best of the exchange. In part I of this paper I aim to extend Psillos' criticisms by suggesting that van Fraassen's critique of IBE is at odds, not only with The Scientific Image but also with his later work. Part II uses some of van Fraassen's ideas to suggest a third way between realist IBE and outright abductive scepticism.
