    A less popular consideration in metaphysics is teleology. ‘Teleology’ is just the jargon-heavy way of saying we are looking to ascertain purpose. Most famously, teleology is used as an argument for God’s existence. While the argument actually predates him by hundreds of years, the teleological argument is most commonly associated with William Paley. Paley argued that the fact that naturally occurring phenomena are often complex and seem to be designed with a purpose in mind was proof that nature must have had an intelligent designer (who Paley then went ahead and assumed was the Judeo-Christian god) .

    Teleology can be found elsewhere in philosophy though. The question most students show up to their Introduction to Philosophy class jazzed to discuss, (but which virtually no philosophy instructor has any interest in talking about) is, “what is the meaning of life?” This is just a teleological question in a different frame – it’s the same as asking, “what is the purpose of life?” Don’t get your hopes up; we aren’t going to answer that question. In fact, we aren’t even going to address the various answers people have suggested over the years. Instead, we want to observe that questions of teleology are themselves an extension of the explanation reflex. Most people jump straight to questioning what the purpose of something is, skipping right over the possibility that there could be no purpose at all. We should be careful not to assume there must be a purpose for all things. In fact, existentialism is a school of philosophical of thought that explicitly rejects the idea that things have innate purposes. Instead, existentialists argue that purposes are assigned to things, including lives, by people.

    Two jointly related concepts worth thinking about when considering teleology are testability and falsifiability. Imagine you or someone you know thinks they have identified the purpose of a naturally occurring thing. How would you go about testing if they were right? Our old friend Wilbur says he has determined that the purpose of trees is to make baseball bats. It won’t be enough for Wilbur to show us that trees can be used to make baseball bats; his claim is much stronger than that. We would need some way of knowing that trees are for baseball bats even though they can be used for all sorts of things.
