Political naturalism is a political ideology and legal system positing that there is a natural law, just and obvious to all, which crosses ideologies, faiths, and personal thinking, and that naturally guaranties justice. It is first explicitly mentioned in Aristotle's Politics. It is inspired by sociological naturalism, and methodological naturalism's belief that the precision of natural sciences can be applied to social sciences, and hence to practical social activities like politics and law. It may be seen as a natural law-based version of legalism and constitutionalism, especially of prescriptive constitutionalism in the way it tries to make a constitution how it should justly be. It also bears relation with many constitutional monarchies, which believe in rule of the law and in certain things who are naturally correct like monarchy and monarchic institutions and traditions.
