The link between time and modality was severed by Duns Scotus, who proposed a notion of possibility based purely on the notion of semantic consistency. 'Possible' means for him logically possible, that is, not involving contradiction.

Gist of Idea

Scotus based modality on semantic consistency, instead of on what the future could allow
