 Nevertheless, he found fault with Reichenbach’s argument for the justification of the rule of induction. Both descriptive and inductive simplicity apply to statements, not to rules, and even if one wanted to apply them to rules, one would have to consider that asymptotic rules do not converge uniformly, which means that they “are not in any sense empirically equivalent” (Salmon 1963c: 28). Simplicity would be a sufficient criterion for justifying the choice of a particular rule from the class of asymptotic rules only if such rules were empirically equivalent, but they are not. Salmon set himself the task of spelling out the conditions under which all asymptotic rules could be rejected except the rule of induction.
