The "Radical Enlightenment" promoted the concept of separating church and state, an idea that often credited to English philosopher John Locke (16321704). According to his principle of the social contract, Locke said that the government lacked authority in the realm of individual conscience, as this was something rational people could not cede to the government for it or others to control. For Locke, this created a natural right in the liberty of conscience, which he said must therefore remain protected from any government authority.
