Well, it’s ideas that hijack our brains. Now, am I saying that a sizable minority of the world’s population has had their brain hijacked by parasitic ideas? No, it’s worse than that. Most people have. There are a lot of ideas to die for. Freedom, if you’re from New Hampshire. Justice. Truth. Communism. Many people have laid down their lives for communism, and many have laid down their lives for capitalism. And many for Catholicism. And many for Islam. These are just a few of the ideas that are to die for. They’re infectious.
