Czeżowskis Axiological Concepts as Full-Fledged Modalities. We Must either Make What is Good, or Become Revisionists

This short paper provides a tentative formalization of Czeżowski's ideas about axiological concepts: Good and Evil are conceived of as modalities rather than as predicates. A natural account of the resulting “ethical logic” appears to be very close to standard deontic logic. If one does not resolve to become an antirealist regarding moral values, a possible way out is to become a revisionist about deontology: convert to intuitionism or some other kind of revisionism in deontic logic, and remain classical in ethical logic.
