In Deep Brain Learning: Pathways to Potential with Challenging Youth, Brendtro, Mitchell, and McCall summarize empathy as follows:
Empathy is the foundation of moral development and pro-social behavior. The original word began in the German language as Einfuhlung which is literally translated as feeling into. Empathy taps the ability of mirror neurons to display in our own brain the emotions, thoughts, and motives of another. Empathy allows us to share anothers joy and pain and motivates care and concern.
