It’s the knowledge of good and evil that isn’t good. Knowing is an experience. For example, if you have been kind to someone then you know kindness, it’s a Spirit. If you are kind to some and unkind to others then you have knowledge of both kindness and unkindness. The tree of the knowledge of good and evil (Light and darkness), in other words a hypocrite. A hypocrite is the worst kind of evil because it proves a person can’t be trusted to be faithful to either. “If you love those that love you, what thanks do you have?”
Knowledge about natural stuff like math, science, history, politics, movies, books, or whatever, is completely irrelevant. Consume as much as you want.
