* Conscience: This is the internal sense of what is right and wrong, guiding our actions and judgments. It's often described as a "voice" or a feeling of guilt or shame when we act against our own values.
* Antecedent: This refers to something that comes before something else.
It's also possible there's a misunderstanding about the term or that it's used in a specific context you haven't provided.
