This week we are learning about helping behavior and altruism.  Altruism is defined as "unselfish regard or devotion to the welfare of others. "  Some might argue, however, that authentic altruism doesn't exist.  Please consider what your opinion is regarding altruism, whether you feel it truly exists or not, and then provide two references that support your argument.  Please cite one professional reference (peer-reviewed journal article) outside of classroom resources.
