Paley's work, and Natural Theology: or Evidences of the Existence and Attributes of the Deity in particular, is admired for its rigorous and logical treatment of evidence. He examines the natural world: plants, animals, human anatomy and the heavens, and from the intricate details he deduces the existence of a benevolent deity, primarily by the now famous watchmaker argument. Though most remembered for Natural Theology, Paley received numerous ecclesiastical honors, including a stall in St. Paul's Cathedral, for his earlier work Evidences of Christianity.

N.B. This edition contains both Natural Theology and Evidences of Christianity.
