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, while the Second Treatise outlines Locke's ideas for a more civilized society based on natural rights and contract theory.
