This is the Jansenists' teaching in their short Catechism on grace: a rational creature without grace would be disordered
This is the teaching of those who follow the doctrine and positions of Jansenius, as can be seen in the short Catechism on grace they published.
In its fourth chapter, after stating that the first man was created in a state of holiness and righteousness, of knowledge and love of God, with God at once forming his nature and giving him grace, they teach that man could not have been created in any other state. God can make nothing that is not well ordered, and a rational creature would be disordered unless it were created in a state of grace.
They prove this from the claim that an intellectual creature's essential order is to tend toward God as toward its center and its source. It cannot tend there except by the help grace supplies. It follows that such a creature, if deprived of grace before it was corrupted by sin, would be outside its proper order.

XIV. Haec est doctrina eorum qui Jansenii doctrinam & placita sequuntur, ut videre est in brevi Catechismo quem de gratia ediderunt. Ibi enim capite quarto, postquam asseruerunt primum hominem fuisse creatum in statu sanctitatis & justitiae, cognitionis & amoris divini, Deo simul naturam formante, & gratiam communicante, docent hominem in alio statu creari non potuisse: quoniam Deus nihil facere potest quod ordinatum non sit: jam vero creaturam rationalem inordinatam fore, nisi in statu gratiae crearetur. Id autem ita esse probant ex eo, quod creaturae intellectualis ordo essentialis est, ut ad Deum tendat tanquam ad centrum suum, & originem suam. Illuc autem tendere non potest, nisi per auxilium quod gratia subministrat. Unde sequitur creaturam talem futuram extra proprium ordinem, si nondum peccato corrupta, gratia privaretur.
