Final Cause

The final cause is the end, goal, or purpose toward which a process is directed — one of Aristotle's four causes and the one most thoroughly rejected by the mechanistic program of the Scientific Revolution. For Aristotle, the final cause of an acorn is the oak tree; the final cause of a house is shelter; the final cause of a heart is pumping blood. The rejection of final causation by Galileo, Descartes, and Newton was not merely a methodological choice but a metaphysical one: the universe, on the new view, operates by efficient causation alone, with no teleology except what is imposed by conscious minds. The revival of systems theory and artificial life suggests that this rejection was premature: goal-directed behavior can emerge from self-organizing dynamics without requiring a conscious designer, making final causation a natural rather than supernatural category.
