“Knowledge is like a knife. You hone it until it’s sharp—really sharp. Then you put it away. The knife can cause both benefits and harm. When a person of discernment uses it, it’s sharp. A person of discernment can get lots of benefits from it because it’s sharp. But a person without discernment can use it to destroy the nation, destroy happiness, destroy harmony—all kinds of things.
And he can do it easily because the knife is sharp.
When knowledge comes to a fool, it’s like putting a weapon in the hands of a bandit or an evil person. He’ll shoot people all over the place, kill all over the place. When knowledge comes to a wise person, the nation and its people get along easily.
These days we pin our hopes on knowledge. We worship knowledge. We rarely worship goodness or correctness. When you have knowledge, you need to have goodness and correctness as well. When you encourage these things, the world will go well. But here it’s, “I’ve got knowledge, so I’m in charge.” In this way, everything goes to hell. That’s what it’s like when you have knowledge without goodness.”
