Final answer:
Thomas Aquinas's argument from design is known as the teleological argument, which posits that the intentional design observed in nature suggests the existence of a designer, who is argued to be God.
Step-by-step explanation:
Thomas Aquinas's argument from design is also called the teleological argument. This argument, also referred to as the design argument, observes the intricacies of design and the order in nature, inferring that such complexity necessitates the existence of a designer, which is argued to be God. The teleological argument is distinguished from other arguments for God’s existence such as the cosmological and ontological arguments.
The teleological argument looks at the apparent purposiveness or the intentional design in the universe, drawing the conclusion that there must be a designer behind it. This concept is significantly different from the cosmological argument, which seeks to prove God's existence based on the existence and order of the universe, and from the ontological argument, which uses a priori reasoning based on the concept of God’s being to argue for His existence.
