“There are several huge monasteries—of which Khang Phi is the greatest—dedicated to the preservation of knowledge. The monks do not sort it into good and evil knowledge, nor do they make moral judgments. They take the position that no knowledge is evil until someone chooses to do evil with it.”

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."

This comment is modified in a later article derived from these talks:
:Frederick Douglass told in his Narrative how his condition as a slave became worse when his master underwent a religious conversion that allowed him to justify slavery as the punishment of the children of Ham. Mark Twain described his mother as a genuinely good person, whose soft heart pitied even Satan, but who had no doubt about the legitimacy of slavery, because in years of living in antebellum Missouri she had never heard any sermon opposing slavery, but only countless sermons preaching that slavery was God's will. With or without religion, good people can behave well and bad people can do evil; but for good people to do evil — that takes religion.
