The converse difficulty: how acts that may or may not happen can be foreseen certainly
In these various ways Christian theologians try to show how human freedom can stand alongside God's foreknowledge of all future things.
Yet it is no less difficult to explain the reverse. If creatures have freedom to act or not to act, how can God foresee their future acts with certainty and without fail? How can anything be known with certainty that has no certain existence either in itself or in its causes, and is as able not to be or happen as to happen and be?
Latin
XXIX. Et sic quidem variis modis ostendere conantur Christiani Theologi, quomodo posita futurorum omnium in Deo praescientia, stare possit humana libertas. Sed non minor est difficultas in explicando quomodo posita libertate, qua creaturae possint agere, & non agere, eorum futuri actus possint a Deo praevideri certo & infallibiliter. Quomodo enim certo cognosci potest quod neque in se, neque in causis suis, certam habet existentiam; sed tam non esse & fieri, quam fieri & esse potest?
