hierarchical_section_title: Rationalism
context_page_description: Rationalism is a branch of philosophy where the validity of an idea is determined by logic, rather than religious means such as revelations, meditation, emotions or observations.
  Rationalist philosophers believe that all knowledge can be understood through a process of reasoning, without any external sources. They do not believe that human beings can understand everything this way, but that it is theoretically possible. Rationalist philosophers attempt to understand ideas like God and the Soul in this manner.
  The first people to talk about rationalism were Marin Mersenne and René Descartes, in the 17th and 18th centuries. Other philosophers who are seen as rationalist today include Baruch Spinoza, Gottfried Leibniz and Immanuel Kant. Famous people opposed to this idea were David Hume and John Locke.
  Rationalism also influenced natural law. Natural law is a theory that says that there are laws given by nature, valid everywhere. Deism was also influenced by rationalism. According to deism, a supreme being created the universe. This being, and other religious truths can be determined by observing nature, and finding natural laws.

This would make religions that are based on revelation unnecessary.
  Rationalism is the view that accepts reason as the chief source of,or justification of knowledge.
