So this is big, this is really individualism. Before it was authority told you what the truth was and Descartes is saying that we can be the factors, that we can investigate and explore through our mind and our reason ideas that can spread like wildfire and affect the world around us. So instead of the world affecting us, we in fact are going to be affecting the world. We are the ones with the flashlight, that is the darkness out there of the middle ages and it's time for us to start doing it because the Catholic Church is certainly not going to be doing it. And then technology is going to aid and abet this revolution as well. This is a revolution, a revolution of ideas. But throw an invention at you, the guy in the middle.
