acedia holds a very special place among them, because it is arises from all the faculties at once, and hence its terrible character. It is found, we could say, at the intersection of two series of vices: one that comes from below (the corporeal passions) and the other that comes from above (the spiritual passions). Acedia affects the body and the soul simultaneously. It takes advantage of a weakness of the body so as to affect the soul.
This is something that I have recognized in myself. When my body cannot resist the temptation to sin, my spirituality suffers as well.
