Teleology is the idea of final causes. Things happen for an external reason and theres an end point in mind. It’s heading towards a ‘destination’, know where it’s going.

Stories have to be teleological. There is no such thing as an accident in a story. Everything crafted within a story is there for a purpose; to get to the end.

The problem with teleology is it’s not the way of the world. Nothing in your life has this shape, only written or visual story material.

Why do stories end? They have a last page or a last frame; they have to! Material in a linear form must end.
