             This was an ideology that was based on the belief in reason and the rational or scientific approach to life and society. It was a mode of thought opposed to ancient traditions of law and political governance, such as the idea of Kingship, which could not be proven or substantiated through rational discourse. These ideals can be found in the works of thinkers like Rene Descartes and Voltaire.
