John Locke 1632-1704

John Locke was an English philosopher and aristocrat who wrote about people and freedom during the Enlightenment period. He considered humans to be individuals with the natural right to defend “life, health, liberty and possessions” and that to do so they found “civil society” which resolves conflicts “civilly” and establishes state and government.

Locke is sometimes referred to as "The Father of Classical Liberalism". His combination of social contract theory with early notions of citizenship and sovereignty form the building blocks of modern democracy. For this reason, it's important to note that, as a British aristocrat, Locke's definition of "humans" or "people" seems to preclude any gender, race, class... any "kind" in general, that isn't his own.
