Acedia

Acedia (/əˈsiːdiə/; also accidie or accedie /ˈæksᵻdi/, from Latin acedĭa, and this from Greek ἀκηδία, "negligence") is a state of listlessness or torpor, of not caring or not being concerned with one's position or condition in the world. It can lead to a state of being unable to perform one's duties in life. Its spiritual overtones make it related to but arguably distinct from depression. Acedia was originally noted as a problem among monks and other ascetics who maintained a solitary life.

The Oxford Concise Dictionary of the Christian Church defines acedia (or accidie) as "a state of restlessness and inability either to work or to pray". Some see it as the precursor to sloth—one of the seven deadly sins. In his sustained analysis of the vice in Q. 35 of the Second Part (Secunda Secundae) of his Summa Theologica, the 13th-century theologian Thomas Aquinas identifies acedia with "the sorrow of the world" (compare Weltschmerz) that "worketh death" and contrasts it with that sorrow "according to God" described by St. Paul in 2 Cor. 7:10. For Aquinas, acedia is "sorrow about spiritual good in as much as it is a Divine good." It becomes a mortal sin when reason consents to man's "flight" (fuga) from the Divine good, "on account of the flesh utterly prevailing over the spirit." Acedia is essentially a flight from the divine that leads to not even caring that one does not care. The ultimate expression of this is a despair that ends in suicide.
