Rationalism and Relativism:Relativism Based on the Theory of Natural Rationality

This article reconstructs the most significant proofs set forth by the Edinburgh school as regards relativism and then makes some critical remarks on them. This is why this school of thought has proposed the theory of natural rationality which considers all epistemological beliefs or assertions as naturally rational. If this theory proves to be successful in its claims, then our secondary explanation of how and why epistemological beliefs or assertions are accepted or rejected needs no rational or irrational grounds, for, according to this theory, all beliefs and theries are rational in nature. Through this speculation, the Edinburgh school mainly aims to make epistemologically identical all epistemological claims in respect of their rationality. Furthermore, the application of the concept of social interests in the theory of this school of thought on "theory of active social use of nature" has been studied and criticized.
