Voetius (Nethenus): the whole controversy turns on whether conditional futures can become future except by God's decree
Voetius, or rather Nethenus in Voetius's work, after arguing at length against middle knowledge, finally concludes: 'From what has been argued so far against middle knowledge, it is clear that the whole difficulty of the present controversy comes down to this point.
Could free conditional futures, which by their own nature are open to being future or not future, have passed from eternity into the state of something future in any way other than by the divine decree, which is the cause of every kind of futurity whatever? This is the foundation of foundations, on which the whole weight of the case rests. It is the postulate that we cannot grant our opponents and they cannot prove to us.'
Latin
XLIII. Voetius vero, seu apud ipsum Nathenus, postquam multis disputavit contra scientiam Mediam, sic tandem concludit, Ex iis quae hactenus contra scientiam mediam disputata sunt, manifestum est totam praesentis controversiae difficultatem recidere in hoc punctum: An futura conditionata libera, ex sua natura ad futuritionem & non futuritionem indifferentia, ab aeterno potuerint transiisse in statum rei futurae aliter quam per decretum divinum, quod causa sit omnis qualiscunque etiam futuritionis? Hoc est fundamentum fundamentorum, cui tota causae moles incumbit; hoc est postulatum illud quod & nos adversariis concedere, & ipsi nobis probare non possunt.
