Compromise
Extremism is often considered as antonym to compromise, which, depending on context, may be associated with concepts of balance or tolerance. In the negative connotation, compromise may be referred to as capitulation, referring to a "surrender" of objectives, principles, or material, in the process of negotiating an agreement. In human relationships, "compromise" is frequently said to be an agreement that no party is happy with, this is because the parties involved often feel that they either gave away too much or that they received too little.
