The law of non-contradiction is found in ancient Indian logic as a meta-rule in the Shrauta Sutras, the grammar of PÄá¹ini, and the Brahma Sutras attributed to Vyasa. It was later elaborated on by medieval commentators such as Madhvacharya.
A contradiction is two propositions used in combination where one makes the other impossible. It is something that is A and non-A at the same time. A contradiction, therefore, cannot exist in reality, since existence exists (whereas a contradiction could not possibly exist). In the cognitive process, reaching a contradiction as a conclusion or evaluation of reality is proof of an error in one's thinking. A square circle is a contradiction in terms.
