 The basic idea behind “variably strict conditionals” (an expression due to D. Lewis 1973) is that the standard of necessity relevant to evaluate a conditional sentence depends on the antecedent. Roughly speaking, in order to evaluate a conditional \(A&gt;B\), one has to extend the reach of the accessibility relation to the “closest” or “most similar” worlds in which the antecedent is true. In what follows we present three related ways of stating the truth conditions of the variably strict conditional.
