John Locke 
Two Treatises of Government and A Letter Concerning Toleration 

John Locke’s 'Two Treatises of Government’ are considered to be some of the most important works of western philosophy ever written. In the first treatise Locke disputes the divine right of monarchial rule principle that is put forth in the book 'Patriarcha’ by Sir Robert Filmer. In the second treatise Locke sets forth the basic principles of natural law that lay the foundation for basic human rights and the government of man. Also contained within this volume is the shorter work, 'A Letter Concerning Toleration.’
