目的(從希臘τ?λο?“結束”,“目的”,或“目標”)是一個結束或目的,在一個相當受限等哲學家亞里士多德所使用的感覺。它是“目的論”一詞的詞根，大致是對目的性的研究，或研究對象的目的、目的或意圖。目的論在亞里士多德的生物學和他的原因理論中居于核心地位。它是一些歷史哲學理論的核心，如黑格爾和馬克思的理論。

A telos (from the Greek τ?λο? for "end", "purpose", or "goal") is an end or purpose, in a fairly constrained sense used by philosophers such as Aristotle. It is the root of the term "teleology", roughly the study of purposiveness, or the study of objects with a view to their aims, purposes, or intentions. Teleology figures centrally in Aristotle's biology and in his theory of causes. It is central to some philosophical theories of history, such as those of Hegel and Marx.
