"Sloth, he says, is not mere laziness — 'lying too long in the bath or postponing our letters of congratulation or condolence' — but rather 'sadness in the face of spiritual good.' It is knowing what will lead one to success, joy, or salvation, but remaining inert because 'the whole apparatus of salvation fills [one] with tedium and disgust.'"
The analysis of sloth itself is interesting, and the essay effectively pins it on Kerry and his party.
My conscience pins it on me, but that's (sigh!) another story.
