 To a large extent, the development of conditional logics over the past century has thus been driven by the quest for a more sophisticated account of the connection between antecedent and consequent in conditionals. A number of conditional logics have thus been developed within the framework of modal logic, to capture the idea that conditional sentences express a necessary connection of sort between antecedent and consequent, whether metaphysical, epistemic, or deontic (see C. I. Lewis 1912; Stalnaker 1968; D. Lewis 1973; Kratzer 2012). A related wave of work encompasses the so-called cotenability theories of conditionals, in which the idea is that a conditional is assertable if its antecedent, together with suitable (co-tenable) premises, entails its consequent (see Chisholm 1946; Goodman 1955; Rescher 1964).
