And they pop up on the exam, what do you know. One of them would be Thomas Hobbes. Thomas Hobbes wrote a book and the book is called Levithan. And I know, I just remember in my mind, it's a big sea monster. Levithan is the idea that Hobbes believed that human beings were evil by nature. That they were greedy and selfish and warfare orientated and that they really couldn't be trusted. So Hobbes believed that human beings, because they couldn't be trusted, would basically have a social contract with a government that would be able to keep us safe from each other.
