This book mainly focused on a comparative analysis of state of nature and social contract in Thomas Hobbes and John Locke political philosophy. Though there are differences between them in adddresing state of nature, which this book explored, for both of them state of nature has so many inconveniences. It is to remedy inconveniences in state of nature that they both argue for the neccesity of state, which should be formed with social contract. However, they differ in their account of social contract. For instance, Hobbes's social contract is somehow rigid that favors government power even at the expense of human liberty where as for Locke Government has only delegated power and the people can rightfully withdraw the government when it acts against the will of the people, and Locke advocated limited government.
