Conscience

Responsibility
Man tried under conscience is the subject of the next age. The sense of responsibility is coupled with the knowledge of good and evil which man got by the fall. Responsibility is not a mode of thought, but the very basis of all morality.
Accusing or Excusing Monitor
We have no prohibition now as in the former age, but instead a living monitor, conscience, "accusing" or else "excusing," but never acquitting.
