10. Modality / A. Necessity / 2. Nature of Necessity

17742	Scotus based modality on semantic consistency, instead of on what the future could allow [Walicki]
	Full Idea: 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.
	From: Michal Walicki (Introduction to Mathematical Logic [2012], History B.4)
