Empathy is the recognition and understanding of the states of mind, beliefs, desires, and particularly, emotions of others. It is often characterized as the ability to "put oneself into another's shoes", or experiencing the outlook or emotions of another being within oneself; a sort of emotional resonance.
It is possible, according to J.L.Moreno, to experience two-way empathy. He termed that phenomenon, tele. The ability to put oneself into another's shoes, he termed role reversal. The combination of several of Moreno's ideas is usually called Psychodrama. The same concepts now exist in many disciplines.
