Moral freedom is impossible too in a universe populated and governed by a rag tag collection of warring gods playing different games with ill defined rules. The Odyssey is more than a grand adventure. Those existential Jobian question are there too. Life, as Homer discovers, is indeed a bitch. I also believe it's the right answer.
Moral freedom is a meaningless concept in a universe where injustice is a no-no.
Moral freedom gives us the right to screw up. When we screw up, people get hurt. I want now to skip forward to a particularly revealing episode in the life of Odysseus. Odysseus expresses doubt and skepticism. Where were you when I needed you, he seems to say.
