Law of noncontradiction
Ravi Zacharias has said most eastern philosophies reject the law of noncontradiction. The law of non-contradiction is found in ancient Indian logic as a rule in the Shrauta Sutras, the writing of Pāṇini, and the Brahma Sutras attributed to Vyasa. It was later elaborated on by medieval commentators such as Madhvacharya. The idea of noncontradiction is rejected in some strands of Buddhism.
