Scroll of The Natural State

I have been pondering this question: How did John Locke use the idea of a "state of nature" to try to establish or figure out what the purpose of government should be? Now I'm not going to say where I got this from but I like it. He used it to come up with the advantages and disadvantages of government. What do people need to be protected but at the same time free? I'll answer that one, rules and people to watch out for them. How can that happen if the person you entrusted to do that has no power over you. You need to give them power so that you can be protected. Can you trust one man with your power?   No.   This is because everybody is self motivated.
