Well Founding Grounding Grounding [PDF]

open access: yesJournal of Philosophical Logic, 2015
Those who wish to claim that all facts about grounding are themselves grounded (“the meta-grounding thesis”) must defend against the charge that such a claim leads to infinite regress and violates the well-foundedness of ground. In this paper, we defend.

Grounding Essentialism and the Challenge of Foundationalism [PDF]

open access: yesحکمت و فلسفه, 2022
Grounding depicts the layered structure of the facts. If we let grounding facts be in the theory, what is their status in the hierarchy? Based on the Purity Principle, grounding facts could not be fundamental because they contain non-fundamental parts ...
