Abstract: We study the extension of propositional ground non-monotonic modal logic to the firstorder case. We show that first-order ground non-monotonic modal logic well complies with first-order default logic by interpreting the latter in the former by the Truszczyński like translation and present a minimal model semantics of first-order ground non-monotonicmodal logic.

Keywords: First-order ground non-monotonic modal logic, first-order default logic, preference semantics, minimal model semantics, Herbrand semantics
