William Paley (1743-1805) was an English Anglican priest, Utilitarian philosopher, and author of influential works on Christianity, ethics, and science, among them the standard exposition in English theology of the teleological argument for the existence of God. He is best known for his work Natural Theology; or, Evidences of the Existence and Attributes of the Deity, which made use of the watchmaker analogy. The argument states that design implies a designer.
