Natural Theology (Or, Evidences of the Existence and Attributes of the Deity, Collected from the Appearances of Nature), was written by English clergyman, Christian apologist, philosopher, and utilitarian William Paley, and originally published in 1805.The book is a work of Christian apologetics, philosophy of religion, and expounds many arguments from natural theology. It also makes a teleological argument for the existence of God, which begins with the famous watchmaker analogy. Natural Theology reads as an extended argument, written around a series of examples. For example, that of finding a watch, the comparison of the eye to a telescope, and the existence of finely adapted mechanical structures in animals, like joints and hinges. Paley argues that these elements lead to the notion of an intelligent Creator, and that a system is always more than the sum of its parts. The final chapters argue that the attributes of God need to be sufficient for scope of his operations, and that God must be good, because his designs manifest within nature are beneficial.
