John Locke laid the groundwork of modern liberalism. He argued that political societies exist to defend the lives, liberties and properties of their citizens and that no government has any authority except by the consent of the people. When rulers became tyrants and act against the common good, then the people have the right of revolution against them. Writing against the backdrop of Charles II's savage purge of the Whig movement, Locke set out to attack the fabric of the divine right of rulers. The rights of property- owners, of Native Americans, and of women and children, the need for economic improvement, the separation of commands, and the nature and limits of consent--these are all topics within Locke's compass and make this book the subject of intense debate. This is the first modernized edition of the Two Treatises based on Locke's own corrected text as he left it for posterity at his death. It includes an introduction, chronology of Locke's life and times, extensive glossary and keyword index.
