Telos
conceptThe ultimate purpose or goal toward which something naturally develops.
The Myth
For Aristotle, everything in nature has a telos — an acorn's telos is to become an oak, a knife's telos is to cut well, and a human's telos is eudaimonia. This teleological worldview shaped Western thought for two millennia. Understanding something meant understanding its purpose. The concept was central to ethics: to know the good life, you must first know what humans are for. Modern science largely abandoned teleological explanation, but the concept persists in philosophy of biology, ethics, and everyday reasoning about purpose and meaning.

Fun Fact
The "tele-" in telephone and television comes from a different Greek word (tele, meaning "far"), not telos — a common confusion even among etymologists.
