What does opening your eyes and realizing your vulnerability have to do with the knowledge of good and evil? Here's the key: You know you're vulnerable. No other animal knows that. You know what hurts you, because you're vulnerable. And now that you know what hurts you, you can figure out what hurts someone else. And as soon as you know what can hurt someone as, and you can use that, then you have the knowledge of good and evil. Well it's a pretty good trick that the snake pulled because it doesn't seem like the thing that we would have exactly wanted if we knew what the consequence was going to be. As soon as a human being is self conscious and aware of his nakedness, then he has the capacity for evil. That's introduced into the world right at that point.
