In his book, Second Treatise of Government, John Locke (1632 - 1704) writes that all humans are born equal with the same ability to reason for themselves, and because of this, government should have limitations to ensure that people are free from the arbitrary will of another person, according to the laws of nature. Government, in Locke's view, is a social contract between the people in control, and the people who submit to it. Locke's book served as a philosophical justification for revolting against tyrannical monarchies in the Glorious Revolution and the American Revolution. His book was practically quoted in the Declaration of Independence. Locke lays out his basis for government on the foundation that people are able to reason. Because of this, people have inherent freedoms or natural rights. Though he believed in reason, Locke was an empiricist, meaning he believed that all knowledge of the world comes from what our senses tell us. The mind starts as a "tabula rasa," latin for an empty slate. As soon as we are born, we immediately begin learning ideas. Thus, all the material for our knowledge of the world comes to us through sensations. Nevertheless, Locke had an unshakable faith in human reason. He believed that people do learn what is right and wrong, regardless of what they choose to do.
