INDIFFERENCE. The state of not being determined to act or not act, to act in one way rather than another. Among persons, active indifference is the ability to determine oneself to a given course of action; passive indifference is the capacity to be moved or determined by someone else. In ascetical theology, indifference is the state of being freed from inordinate attachments or desires that would keep a person from total dedication to God. It is internal liberty that enables the soul to give itself unreservedly to follow Christ.
