So let's go through a couple of other Enlightenment thinkers and then we can probably do it for you. I just have to cough really quick. And I would move on now and go to kind of our government philosophers. So Descartes is really the guy who said that we could do that. We can investigate how we are in relationship to our government and how that system might work rather than being told how it works. So we get different philosophers, different writers that are going to do just that. And they pop up on the exam, what do you know.
