Thomas Hobbes thought that all humans were naturally selfish and greedy, and needed the power of an absolute ruler to hold them back. He thought that the people should obey the rulers every word. Locke said that a true government was meant to protect all natural rights of a person, and that the people had to have a voice in government. He was against the monarchy, because he believed that it was not protecting the natural rights of the people, and reversely, going against them.
Both Hobbes and Locke shared ideas based on the social contract theory. Not only did many enlightenment thinkers want to form government based on ideas from the theory, but, it supported John Locke's idea of natural rights.
