The Governments and States of Locke, Aquinas, and St. Augustine

In John Locke's Second Treatise of Government, he identifies a government that is of the peoples consent with his essential raison d΄être being the preservation and protection of personal property. This type of government is extremely comparable with the type of government that St. Augustine describes in his work City of God, while at the same time contrasts the views of Aquinas in the ways a state should operate. The end goal of how each of these philosophers' states purposes presents the greatest split between each of their philosophies. To understand how each of these philosophers' states are similar and different from each other, a deeper analysis is necessary.
The first and possibly most striking similarity between the states that both Locke and St. Augustine propose lies in the fact that both see the state as a necessary evil. Locke describes the perfect life as one in the "state of nature", where there are limitless boundaries to freedom. Within these limitless boundaries to do whatever you want lays the ability for others to do harm to you and your property, because they have complete freedom as well. In order to overcome this lack of security, Locke describes the state as a necessary evil which one must give up certain freedoms in order to be protected under the rule of law. This is similar to St. Augustine in the respect that within the world there are evil men who will do harm to others. Augustine argues that laws are necessary to make sure that people can live with the peace of mind that they are protected from the sins of others.
One of the contrasting points the states of Aquinas and Locke possess is rooted in how each state should set up and decide their laws. Aquinas argues that we should set up our laws based on high morals, which all men could agree on, and on the high ideals of natural law. Locke disagrees with this in the respect that all men are Tabula Rasa, which begin life as blank slates and develop their views and ideas
