This knowledge of what would be is placed before every free decree of God's will
Foreknowledge of what will absolutely happen must follow some decree of God's will. By that decree he has resolved to create these or those agents, to place them in this or that order of things, and to concur with them in acting as needed.
By contrast, they hold that God's knowledge of things that will not simply happen, but would happen only on some supposition, comes before every free decree of his will. That is, to speak in our human way of conceiving, before God made any decree about anything at all, he knew with certainty and distinctness what any possible creature would freely do. He knew this on the supposition that he chose to create it, not to withhold his concurrence from it, and to set these or those objects before it in these or those circumstances.
Latin
III. Porro, cum praescientia eorum quae sunt absolute futura, necessario sequatur decretum aliquod divinae voluntatis, quo statuerit haec & illa agentia creare, & in hoc, vel illo rerum ordine constituere, atque cum illis, prout necesse est, ad agendum concurrere; hanc scientiam eorum quae simpliciter futura non sunt, sed ex hypothesi tantum futura essent, volunt in Deo praecedere liberum omne voluntatis decretum. Nempe juxta nostrum concipiendi modum, Deum, priusquam ullum de re quacunque decretum condiderit, certo & distincte novisse quid creatura quaelibet possibilis libere factura sit, si voluerit Deus illam creare, & concursum suum illi non denegare, atque haec & illa objecta, sub circumstantiis istis & illis ei proponere.
