Think about it this way: When you’re at home and the power goes out, you call an electrician. He shows up. What do you want? You want the lights back on. Do you want to know everything he knows? Do you follow him around and ask him for the schematics of the breaker box? Perhaps you do, but I don’t. I don’t know how electricity works, and it doesn’t matter. I know one thing; the electrician can fix it so that when I hit the switch the lights turn on, and that’s about all I want to know.
