Locke, John /lɒk $ lɑːk/ 
 (1632–1704) an English 
philosopher who developed the idea of 
empiricism in his
 Essay Concerning Human Understanding. In his
 Two Treatises on Civil Government he wrote that a king or government received the right to rule from the people and not from God, and that the people should be able to change their government if they were not satisfied with it. These ideas influenced the 
Declaration of Independence in the US.
