Discussion about the existence of God of William Perry and David Hume is called theoretical argumentation or design theory. Discussion from design is an argument about the existence of God and the existence of certain creator based on the idea of order and purpose in the universe. Hume adopted a method against design argument, Paley defended it. Both Hume and Paley are making very strong claims, but we will reach the conclusion to distinguish which philosopher is taking a stronger position.
Hume also advocated a discussion to support and oppose the purpose of the argument in his dialogue on natural religion. The role of Cleanthes summarizes the theoretical argument that compares the universe with an artificial machine and derives a conclusion based on the principle of similar effect and similar reasons that must have wisdom of design. It turns out that it is a wonderful machine fragmented into countless machines. Also, we recognize again that the degree of fragmentation exceeds the range that can be interpreted by tracking human's senses and abilities. These different machines, even their smallest part, can be adjusted precisely to each other, and everyone who takes it into account is admired. In nature as a whole, the adaptation of means curiosity to purpose is completely analogous to human design production; human design, thought, wisdom, and wisdom
Modern argumental arguments are somewhat different from the construction theory of Paley. Paley is particularly impressed with the design of biological systems such as eyes and animals, but contemporary editorials often find evidence of design in physics. Modern discussion tends to focus on the "fine tuning" of the universe, and indeed it is the fact that in order to support life ("fine tuning") it is necessary. One of the advantages of contemporary design theory compared to Paley is that it is less susceptible to attack based on evolution theory. From the perspective of Paley, people oppose the evolution that explains the emergence of biological designs, but the evolutionary process does not apply to the laws of nature.
