In this candid chronicle of what many would call a prolonged depression occasioned in part by her husband's illness and death, Norris, a popular memoirist and essayist, seeks carefully to distinguish the psychological or psycho-medical category of "depression" from the spiritual state of "acedia" or, more bluntly, "sloth," in its oldest and most precise sense.  In doing so she raises important questions about widespread and often imprecise use of categories derived from clinical psychology, an imprecision that may muddy the distinction between spiritual and psychopathological experience.

"Acedia" she defines as a failure of will, signifying a need for spiritual guidance and prayer, whereas "depression" requires medical treatment.  Going beyond the confessional, Norris suggests that acedia may be an endemic condition among middle-class Americans, over-busy but spiritually slothful.  The book is loosely organized, often characteristically lyrical, and more invitational than diagnostic.  Her purpose, finally, seems to be to inspire readers to embrace simple life-giving spiritual disciplines like reading the Psalms as a stay against excessive self-preoccupation and actual depression as well as spiritual depletion.
