Enright Forgiveness Inventory

"Forgiveness is a person-to-person response to unfairness, which leads the offended side to give up the right for resentment toward the offending person, eventually influencing the development of compassion, care, and even moral love toward the other.... forgiveness as a moral response involves the following major domains of human development: positive emotions (e.g., feelings of empathy), negative emotions (e.g., feelings of anger and resentment), positive behaviors (e.g., altruism) and negative behaviors (e.g., revenge-seeking) and, finally, positive (e.g., he/she is a good person) or negative (e.g., condonation) thoughts toward the offending person.

--Robert D. Enright and Julio Rique, EFI Manual
A PSYCHOLOGICAL DEFINITION

Interpersonal Forgiveness is a willingness to abandon one's right to resentment, negative judgment, and indifferent behavior toward one who unjustly injured us, while fostering the undeserved qualities of compassion, generosity and even love toward him or her.
