watchmaker analogy

The watchmaker analogy, or watchmaker argument, is a teleological argument for the existence of God. By way of an analogy the argument states that design implies a designer. In the 17th and 18th centuries, the analogy was used (by Descartes and Boyle, for instance) as a device for explaining the structure of the universe and God's relationship to it. Later, the analogy played a prominent role in natural theology and the "argument from design," where it was used to support arguments for the existence of God and for the intelligent design of the universe.

The most famous statement of the teleological argument using the watchmaker analogy was given by William Paley in 1802. Paley's argument was seriously challenged by Charles Darwin's formulation of the theory of natural selection, and how it combines with mutation to improve survivability of a species, even a new species. In the United States, starting in the 1980s, the concepts of evolution and natural selection (usually referred to as "Darwinism") became the subject of a concerted attack by Christian creationists. This attack included a renewed interest in, and defense of, the watchmaker argument by the intelligent design movement.

The Watchmaker argument

The watchmaker analogy consists of the comparison of some natural phenomenon to a watch. Typically, the analogy is presented as a prelude to the teleological argument and is generally presented as:

1. If you look at a watch, you can easily tell that it was designed and built by an intelligent watchmaker.
2. Similarly, if you look at some natural phenomenon X (a particular organ or organism, the structure of the solar system, life, the entire universe) you can easily tell that it was designed and built by an intelligent creator/designer.
