Definition of altruism. 1  1 : unselfish regard for or devotion to the welfare of others charitable acts motivated purely by altruism. 2  2 : behavior by an animal that is not beneficial to or may be harmful to itself but that benefits others of its species.
Cognitive Reasons: While the definition of altruism involves doing for others without reward, there may still be cognitive incentives that are not obvious. For example, we might help others to relieve out own distress or because being kind to others upholds our view of ourselves as kind, empathetic people.
