Peter Lipton has attempted to flesh out a model of Inference to the Be
st Explanation (IBE) by clarifying explanation in terms of a causal mo
del. But Lipton's account of explanation makes an adequate explanation
depend on a principle which is virtually identical to Mill's Method o
f Difference. This has the result of collapsing IBE on Lipton's accoun
t of it into causal inference as conceived by the Causal-Inference mod
el of induction. According to this model, many of our inductions are i
nferences from effects to their probable causes, and Mill's Methods ar
e canons to guide such inferences. Thus, Lipton's account of IBE fails
to represent an advance over the already familiar Causal-Inference Mo
del of induction.
