Rationalism

In epistemology, rationalism is the view that "regards reason as the chief source and test of knowledge"[1] or "any view appealing to reason as a source of knowledge or justification".[2] More formally, rationalism is defined as a methodology or a theory "in which the criterion of the truth is not sensory but intellectual and deductive".[3] In an old controversy, rationalism was opposed to Empiricism, where the rationalists believed that reality has an intrinsically logical structure. https://en.wikipedia.org/wiki/Rationalism
