### **Succinct** Teleology is the explanation of phenomena by their **purpose or goal** rather than by their causes. --- ### **Simple** Imagine you see a flower turning toward the sun. A **teleological** explanation says: _it turns to get sunlight in order to survive_. It focuses on **what something is for**, not **what caused it**. This kind of thinking is common in biology, philosophy, and even in daily life when we say _“the heart is for pumping blood”_. --- ### **Accurate** The term _teleology_ comes from the Greek _telos_ (end, goal) and _logos_ (reason, explanation). It contrasts with **mechanistic** or **causal** explanations, which describe _how_ things happen rather than _why_ they aim toward an end. In philosophy, **Aristotle** formalized this through his concept of the **final cause** — one of four types of causes. In modern science, teleological language is often reinterpreted metaphorically or functionally (e.g., in evolutionary biology, where purposes are reframed as selected functions). Teleological reasoning can be useful for describing **systems with goal-directed behavior**, but it risks **anthropomorphism** if the purpose is imposed by the observer rather than inherent in the system.
