Acédie
ἀκηδία (akèdia)
Spiritual torpor and disgust that seizes the monk in the middle of the day, which monastic tradition calls "the noonday demon" after Psalm 90/91. Evagrius of Pontus ranks it among the eight evil thoughts and describes it as the heaviest: neither sensuality nor vainglory, but a revulsion toward the present hour and the place where one is. The Greek word *akèdia* literally means "absence of care," the inability to concern oneself with what should matter. Its surest sign is not rest but restlessness: disgust for the cell drives one to leave it.
J'étais, dit-il, assis un jour dans ma cellule, et je sentais un si grand découragement dans mon cœur, que je pensais presque à la quitter.
The Greek word akèdia combines the privative a- with kḗdos, meaning care, concern—the attention one gives to something or someone. Akèdia is thus first and foremost a failure of care: not the suffering of having too much to do, but the inability to hold fast to what one is doing. Evagrius Ponticus, who provided its first precise description in the 4th century, locates it in the middle of the day, when the sun seems to stand still—hence the name it has retained, “the noonday demon,” drawn from Psalm 90/91. The monk rereads the same line ten times, glances out the window to see if anyone is coming, counts the hours until the next meal.
What makes it so insidious is that it does not resemble a vice. It wears the guise of good sense: the cell is too harsh, the rule too rigid, one would be of more use elsewhere—among the brothers, in the world. The Desert Fathers saw beneath these arguments the same single impulse—a flight. John Climacus speaks of it in the first person, seated in his cell, overcome by such discouragement that he thinks “almost of leaving.” Akèdia does not attack faith head-on; it attacks place, hour, duration—everything that demands one stay put.
This is why the remedy handed down by tradition is not rest but stability: to remain, precisely when everything urges departure. The monk does not argue with the thought; he refuses to move. The torpor of akèdia is thus the exact double of a restlessness: the soul wants both to do nothing and to change everything. It is on this weakened ground that vainglory later takes root, offering escape as a promotion.
Hence a distinction that must be held firmly. Akèdia is ≠ sloth: sloth seeks rest and finds it, while akèdia tolerates neither rest nor effort and searches everywhere for a way out. Nor is it clinical depression, which is a disorder of mood without spiritual object or ascetic remedy. Akèdia, as the monks describe it, is a temptation: a disgust directed at a specific place—the cell—and undone by refusing to leave it.
