 In Aristotle’s (384–322 BCE) seminal biological writings, the external teleology of a designer-creator was replaced by an internal teleological purposiveness associated with the immanent action of an internal cause—in living beings their informing soul (psuche)— which functioned as the formal, final and efficient cause of life (Aristotle, De Anima II: 415b, 10–30). Aristotle also did not endorse the concept of an historical origin of the world, affirming instead the eternity of the world order (Physics, I: 192a, 25–34). At least this was how he was understood by a later tradition (Dales and Argerami 1991).
