In this episode I read from Voltaire's Philosophical Dictionary. He had much to say about it. The truth that we are machines is so difficult for most people to accept. When you look at the machines such as computers, phone, cars, airplanes and others that humans depend on, you will be glad that they don't have a free will. We expect machines to do their job reliably and deterministically. While humans are machines, they are far less reliable or predictable than machines built by humans. This is only because we don't understand all the causes of what they do. We are machines assembled by more causes than we can fully know.
