accidie: translation
State that inhibits pleasure and prompts the rejection of life; one of the Seven Deadly Sins . Aquinas associates it with turning one's back on things, through depression or self-hatred, and nicely defines it as a torpor of spirit which prevents one from getting down to anything good (Summa Theologiae, IIa 35. 1). Often it is translated as sloth, which is actually quite different. See also apathy.
