Jansenius, book 3 chapter 19: every love but charity is blameworthy cupidity
This is seen especially in chapter 19 of that third book of On the state of fallen nature, already cited often. Its title is 'There is no middle between charity and blameworthy cupidity'. There he proves it from the fact that there is no middle between the love of God and the love of the creature.
'All the affections of the mind,' he says, 'turn on the love of some thing as on a hinge. That love can only be love of the Creator or love of the creature. The first is good; the second is blameworthy, since the Apostle calls it love of the world and, according to Augustine, it is the very character of sin, which rules in every kind of wrongdoing. So it is surely clear that every love other than that charity is that blameworthy cupidity.'
Latin
XL. Id praesertim videre est libri illius tertii de statu naturae lapsae saepius jam citati capite decimo nono. Cujus titulus est, Non datur medium inter charitatem & culpabilem cupiditatem. Ubi istud probat ex eo quod nullum est medium inter amorem Dei, amoremque creaturae. Omnes enim, inquit, affectus animi in alicujus rei amore velut cardine versantur: qui cum non possit esse alius, nisi vel Creatoris, vel creaturae, & ille bonus hic culpabilis sit, utpote amor mundi ab Apostolo vocatus, & juxta Augustinum, ipsa ratio peccati, quae in omni malefaciendi genere dominatur: profecto liquet omnem amorem praeter istam charitatem esse culpabilem illam cupiditatem.
