Sloth is not to be confused with laziness. A lazy man, a man who sits around and watches the grass grow, may be a man at peace. His sun-drenched, bumblebee dreaming may be the prelude to action or itself an act well worth the acting.
A slothful man, on the other hand, may be a very busy man. He is a man who goes through the motions, who flies on automatic pilot. Like a man with a bad head cold, he has mostly lost his sense of taste and smell. He knows somethings wrong with him, but not wrong enough to do anything about. Other people come and go, but through glazed eyes he hardly notices them. He is letting things run their course. He is getting through his life.
