Abstract

Inference to the best explanation has at times appeared almost indistinguishable from a rule that recommends simply that we should infer the hypothesis which is most plausible given available evidence. In this paper I argue that avoiding this collapse requires the identification of peculiarly explanatory virtues and consider Woodward's concept of invariance as an example of such a virtue. An additional benefit of augmenting IBE with Woodward's model of causal explanation is also suggested.
