Stanford Encyclopedia of Philosophy “Teleological Arguments for God's Existence”
Some phenomena within nature exhibit such exquisiteness of structure, function or interconnectedness that many people have found it natural - if not inescapable - to see a deliberative and directive mind behind those phenomena. The mind in question, being prior to nature itself, is typically taken to be supernatural. Philosophically inclined thinkers have both historically and at present labored to shape the relevant intuition into a more formal, logically rigorous inference. The resultant theistic arguments, in their various logical forms, share a focus on plan, purpose, intention and design, and are thus classified as teleological arguments (or, frequently, as arguments from or to design).
A teleological argument, or argument from design, is an argument for the existence of God or a creator based on perceived evidence of order, purpose, design, or direction—or some combination of these—in nature. The word “teleological” is derived from the Greek word telos, meaning end or purpose. Teleology is the supposition that there is purpose or directive principle in the works and processes of nature.
