Here: This syllogism is of considerable practical importance: This raises the issue of denying the consequent, ~q. If p –> q and ~q, then as q is necessary for p, ~p. Where, p is sufficient for q, by reason of its core characteristics, the states of affairs associated with p, causal power, requirement of logic of being etc. Let us note, p –> q is equivalent in import to ~q –> ~p. (Let’s add, that denying the antecedent, thinking this falsifies the consequent also fails, p –> q does not mean there isn’t another way, say r, to get q. There’s more than one way to skin a cat-fish.) Connected to ID, Newton’s rules demand that causal adequacy be shown Read More ›
