John Locke in particular exemplified this new age of political theory with his work Two Treatises of Government. In it Locke proposes a state of nature theory that directly complements his conception of how political development occurs and how it can be founded through contractual obligation. Locke stood to refute Sir Robert Filmer's paternally founded political theory in favor of a natural system based on nature in a particular given system. The theory of the divine right of kings became a passing fancy, exposed to the type of ridicule with which John Locke treated it. Unlike Machiavelli and Hobbes but like Aquinas, Locke would accept Aristotle's dictum that man seeks to be happy in a state of social harmony as a social animal. Unlike Aquinas's preponderant view on the salvation of the soul from original sin, Locke believes man's mind comes into this world as tabula rasa. For Locke, knowledge is neither innate, revealed nor based on authority but subject to uncertainty tempered by reason, tolerance and moderation. According to Locke, an absolute ruler as proposed by Hobbes is unnecessary, for natural law is based on reason and seeking peace and survival for man.
