Faustian bargain

Faustian bargain, a pact whereby a person trades something of supreme moral or spiritual importance, such as personal values or the soul, for some worldly or material benefit, such as knowledge, power, or riches. The term refers to the legend of Faust (or Faustus, or Doctor Faustus), a character in German folklore and literature, who agrees to surrender his soul to an evil spirit (in some treatments, Mephistopheles, or Mephisto, a representative of Satan) after a certain period of time in exchange for otherwise unattainable knowledge and magical powers that give him access to all the world’s pleasures. A Faustian bargain is made with a power that the bargainer recognizes as evil or amoral. Faustian bargains are by their nature tragic or self-defeating for the person who makes them, because what is surrendered is ultimately far more valuable than what is obtained, whether or not the bargainer appreciates that fact.
