“now must thou cast off all sloth…. for sitting on down or under blankets none comes to fame, and without it he that consumes his life leaves no trace of himself on earth, as smoke in air or foam on the water. rise, therefore, conquer thy distress with the soul, which conquers in every battle if it doesnot sink with its bodys weight. there is a longer stair which must be climbed.”
Dante, Commedia, Inferno XXIV, 46-55.
