Kratzer (1981) discussed a naıve premise semantics of counterfactual conditionals, pointed to an empirical inadequacy of this interpretation, and presented a modification-partition semantics-which Lewis (1981) proved equivalent to Pollock's (1976) version of his ordering semantics. Subsequently, Kratzer (1989) proposed lumping semantics, a different modification of premise semantics, and argued it remedies empirical failings of ordering semantics as well as of naïve premise semantics. We show
