Natural-law argument

The Natural-law argument for the existence of God states that the observation of governing laws and existing order in the universe indicates the existence of a superior being who enacted these laws. The argument was popularised by Isaac Newton, René Descartes, and Robert Boyle. The argument of natural laws as a basis for God was changed by Christian figures such as Thomas Aquinas, in order to fit biblical scripture and establish a Judeo-Christian teleological law.

Bertrand Russell criticized the argument, arguing that many of the things considered to be laws of nature, in fact, are human conventions. The teleological argument assumes that one can infer the existence of intelligent design merely by examination, and because life is reminiscent of something a human might design, it too must have been designed. However, considering "snowflakes and crystals of certain salts", "[i]n no case do we find intelligence". "There are other ways that order and design can come about" such as by "purely physical forces."
