 Notably, (Cons) was defended by Hempel (1945) and, in fact, one can show that it follows from the conjunction of (qualitative) Confirmation Complementary and the Special Consequence Condition, and so from both Hempelian and \(F\)-confirmation. This is but one sign of how stringent the Special Consequence Condition is. Mainly because of the latter, both the Hempelian and the firmness views of confirmation must depart from the plausible HD idea that hypotheses are generally confirmed by their verified consequences (see Hempel 1945, 103–104). We will come back to this while discussing our next topic: a very different Bayesian explication of confirmation, based on the notion of probabilistic relevance.
