Third difference: why the aid is needed
Thesis LXXVI. Further, the recent Thomists hold that physical predetermination is necessary for the human will to act well because the will, like all other secondary causes, needs to be premoved by God, the First Cause, in order actually to act. They also derive this necessity from the will's indifference, which on that account must be determined to act by a higher cause.
Jansenius, however, thinks the efficacious aid of divine grace necessary to the human will for one reason only: the wound inflicted by sin, and the weakness contracted from the concupiscence that clings to fallen man.
Latin
LXXVI. Praeterea physicam praedeterminationem voluntati humanae ad bene operandum necessariam esse, ideo existimant Thomistae recentiores, quod voluntas, ut omnes reliquae causae secundae, opus habet a Deo causa prima praemoveri, ut actu operetur. Atque etiam illam necessitatem petunt a voluntatis indifferentia, quam propterea necesse sit a causa superiori ad agendum determinari. Sed Jansenius non alia de causa gratiae divinae auxilium efficax humanae voluntati necessarium putat, quam propter vulnus a peccato inflictum, & infirmitatem ex concupiscentia homini lapso adhaerente contractam.
