detachment

n. separation; disinterest, aloofness; lack of bias; division of soldiers who have been sent on a mission

Detachment is a state in which a person overcomes his or her attachment to desire for things, people or concepts of the world and thus attains a heightened perspective. Detachment as release from desire and consequently from suffering is an important principle in Hinduism, Buddhism, the Bahá'í Faith and Kabbalah. In psychology it is referred to as dissociation or apathy. Many feminist epistemologists have questioned the viability of such a state of detachment, particularly as it contributes to the 'view from nowhere' of objectivity.
