 Arnauld quotes Malebranche’s statement, “The à priori proofs are too abstract to convince most people of the truth I am proposing. It is more à propos to prove it à posteriori,” and goes on to consider the a posteriori arguments (OA, 39:625–43). He is less sarcastic in dealing with these arguments than with the a priori ones. He says that there are “three or four of them, but they all amount to the same thing: There are graces that are inefficacious, and this would not occur if God gave His graces by particular volitions.” He mentions three such arguments, based on the premise that graces are given to sinners who are not entirely converted; on the premise that grace often falls upon hearts disposed in such a way that the grace does not bear fruit; and, finally, on the premise that graces given to sinners sometimes end up making them even more guilty.
