Show synopsis The Two Treatises of Government (or Two Treatises of Government: In the Former, The False Principles and Foundation of Sir Robert Filmer, And His Followers, are Detected and Overthrown. The Latter is an Essay concerning The True Original, Extent, and End of Civil-Government) is a work of political philosophy published anonymously in 1689 by John Locke. The First Treatise attacks patriarchalism in the form of sentence-by-sentence refutation of Robert Filmer's Patriarcha and the Second Treatise outlines a theory of political or civil society based on natural rights and contract theory. In the Second Treatise Locke develops a number of notable themes. It begins with a depiction of the state of nature, wherein individuals are under no obligation to obey one another but are each themselves judge of what the law of nature requires. It also covers conquest and slavery, property, representative government, and the right of revolution.
