Here comes a definition of Goodwill by Roberto Assagioli from this source.
Here, the love element and the will element are both present and active, in more or less balanced proportions. It can be said that the fundamental or primary quality of goodwill is love, in its aspects of understanding and compassion. It then arouses the urge, the determination, to act in order to resolve conflicts, to counterbalance selfish and separative tendencies and activities, to create right human relationships and also right relationships with all living beings and with nature in general. Thus, it can be said that this initial love arouses the action of the will in its various stages and aspects.« Back to Glossary Index
