Can Counterfactuals Be Accounted for as Tense and Modality Combined?

Abstract

Linguistic expressions of counterfactually usually accomany tense and modal morphemes, which opens up the question whether they can be reduced into logical operations pertinent to the two. An attempting trial in this approach appears to be successful, but can not satisfactorily explicate failures of strengthend antecedent and transitivity, crues ingenious to counterfactuals. Davidian possible world semantics provides a reasonable account for why the apparent success cannot be extended further by always accompanying incompatible worlds for each stage of the conjunct counterfactuals.
