 Logics that combine operators for (impersonal) obligation and agency have been very widely  employed.[68]  Krogh and Herrestad 1996 reinterpret the Meinong-Chisholm analysis so that the deontic operator is personal, yet not agential. This is arguably a more plausible way to preserve a componential analysis of agential obligation. McNamara 2004a also makes the case that a person’s being obligated to be such that a certain condition holds (e.g., being obligated to be at home at noon, as promised) is the more basic idiom, and being obligated to bring about something is just being obligated to be such that you do bring it about.
