As one of the early Enlightenment philosophers in England, John Locke sought to bring reason and critical intelligence to the discussion of the origins of civil society.Endeavoring to reconstruct the nature and purpose of government, a social contract theory is proposed. The Second Treatise sets forth a detailed discussion of how civil society came to be and the nature of its inception. Locke's discussion of tacit consent, separation of powers, and the right of citizens to revolt against repressive governments, has made The Second Treatise one of the most influential essays in the history of political philosophy.
