One mistake Eriugena claims to find in Gottschalk is a confusion between God’s foreknowing that I will do something, and His predestining that I will do it (§2.2, 5.1, 11.7). As Boethius had already argued in late antiquity, knowing that something is going to happen doesn’t mean causing that thing to happen. Thus, God can foreknow sin without predestining it.
