The teleological or physico-theological argument, also known as the argument from design, or intelligent design argument is an argument for the existence of god or, more generally, for an intelligent creator based on perceived evidence of deliberate design in the natural world. The argument as he constructed it is thus an argument from analogy modern teleological arguments look somewhat different to that constructed by paley while paley was particularly impressed by the appearance of design in biological systems, such as the eye, or animals, modern teleological arguments often find evidence of design in physics.
The teleological argument is a posteriori and like the cosmological argument, attempts to prove the existence of god it claims that certain phenomena within the universe appear to display features of design and are perfectly adapted to fulfil their function.
This argument, also referred to as the “design argument”, is an a posteriori argument claiming that through observation of the universe we can discover evidence of intelligent design that justifiably infers the existence of a “grand designer”, usually posited as god.
The teleological argument reflects one of three possibilities for the existence of this incredible fine-tuning: law, chance or design scientists have puzzled over it for years and have found no natural laws that can account for it.
Teleological arguments are arguments from the order in the universe to the existence of god they are also known as arguments from design (or, to be precise, arguments to design) the name “the teleological argument” is derived from the greek word telos, meaning “end” or “purpose” when such arguments speak of the universe being ordered, they mean that it is ordered towards some end or purpose. The teleological argument is an attempt to prove the existence of god that begins with the observation of the purposiveness of nature the teleological argument moves to the conclusion that there must exist a designer. A teleological argument for god’s existence is so named because it argues, in so many words, that the material universe is purposeful, or goal-directed, in nature and from that it reasons to god’s existence as the architect, or designer, of the material universe.
The teleological argument applies this principle to the whole universe if designs imply a designer, and the universe shows marks of design, then the universe was designed clearly, every life form in earth's history has been highly complex.
The teleological argument is also known as the argument from design quite simply, it states that a designer must exist since the universe and living things exhibit marks of design in their order, consistency, unity, and pattern a common analogy of this is the watchmaker argument, which was given.
