Pathei-Mathos

The Greek term πάθει μάθος (pathei-mathos) derives from The Agamemnon of Aeschylus (written c. 458 BCE), and can be translated as learning from adversary, and thus interpreted as implying that wisdom arises from (personal) suffering and that personal experience is the genesis of true learning.

To Adam he said, Because you listened to your wife and ate fruit from the tree about which I commanded you, You must not eat from it, Cursed is the ground because of you; through painful toil you will eat food from it all the days of your life.

Gen 3,17
