The contradiction between the quatrains is mainly shown by the use of passive and active verbs. The first quatrain contradicts the second quatrain, because it shows nature in the eyes of science, the second quatrain is the active part: "Till rising and gliding out, I wander’d off by myself" (7), " Look’d up in perfect silence at the stars " (9).
