23283 Necessity implies possibility, but in experience it matters which comes first [Williams,B]
10. Modality / B. Possibility / 8. Conditionals / a. Conditionals

10. Modality / B. Possibility / 8. Conditionals / c. Truth-function conditionals
13764 Are conditionals truth-functional - do the truth values of A and B determine the truth value of 'If A, B'? [Edgington]
