Le Blanc: an endless earthly life without supernatural help is improbable; he follows Pierre du Moulin. De Primi Hominis Immortalitate closes
But that man could have lived forever an earthly, animal life without any supernatural gift or help, as the first opinion maintains, seems to me in no way probable. I cannot see how a body made of the elements, and so naturally and in itself corruptible, could be kept from corruption forever without some help above nature.
Here I follow the judgment of Pierre du Moulin, who also has no doubt that man, however perfect the natural balance of his body, needs supernatural help and God's continual aid to keep that good balance (eukrasia) (Du Moulin, On the State of Innocence, thesis 50).
Latin
XXXV. Hominem autem in aeternum vivere potuisse vita terrena atque animali, ut prior illa sententia asserit, absque ullo supernaturali dono, vel auxilio, nullo modo mihi probabile videtur. Nec enim capere possum quomodo corpus ex elementis constans, adeoque naturaliter & in se corruptibile, absque ullo supra naturam auxilio, a corruptione possit in perpetuum praeservari. Qua in re judicium sequor Petri Molinaei, cui quoque dubium non est quin, homo quantumvis perfecto corporis temperamento naturali, opus habeat auxilio supernaturali, & Dei ope continua ad servandam hanc εὐκρασίαν. De statu Innocentiae Thesi 50.
