Matthew Fielding Locke
After the war, Locke returned to Mississippi, and in 1849 married Elizabeth A. Biue. Shortly thereafter they moved to Upshur County, Texas. He established a plantation about 13 miles (21 km) northeast of present-day Gilmer and founded the nearby town of LaFayette (which he named after his son, LaFayette C. Locke, who was born in 1850). Locke began the first of two terms as a state representative in 1855 in the Sixth Texas Legislature. In the Seventh Legislature, Locke was elected Speaker of the House "pro tempore" on 26 December 1857 when Speaker William S. Taylor took ill. When Taylor resigned on 18 January 1858, Locke was elected Speaker over Reps. Isaac N. Dennis and John Henry Brown, 39 votes to 14 and 13, respectively.
Natural and legal rights
This marked an important departure from medieval natural law theories which gave precedence to obligations over rights.
John Locke (1632 – 1704) was another prominent Western philosopher who conceptualized rights as natural and inalienable. Like Hobbes, Locke believed in a natural right to life, liberty, and property. It was once conventional wisdom that Locke greatly influenced the American Revolutionary War with his writings of natural rights, but this claim has been the subject of protracted dispute in recent decades. For example, the historian Ray Forrest Harvey declared that Jefferson and Locke were at "two opposite poles" in their political philosophy, as evidenced by Jefferson’s use in the Declaration of Independence of the phrase "pursuit of happiness" instead of "property." More recently, the eminent legal historian John Phillip Reid has deplored contemporary scholars’ "misplaced emphasis on John Locke," arguing that American revolutionary leaders saw Locke as a "commentator" on established constitutional principles. Thomas Pangle has defended Locke's influence on the Founding, claiming that historians who argue to the contrary either misrepresent the classical republican alternative to which they say the revolutionary leaders adhered, do not understand Locke, or point to someone else who was decisively influenced by Locke. This position has also been sustained by Michael Zuckert.
