The development of Navya Nyaya (Neo-logistic system) begins with the entry of Gangesh Upadhyaya in the field of Indian Nyaya in c. 13th A. D. But for four centuries the Jaina logicians were unacquainted with this new literary genre and continued to follow the style of Vadidevasuri. Thus, the development of Jaina Logic (Nyayasastra) remained interrupted after c. 12thA.D.

It was the period of origination of Anekāntavāda.
Basically, the non-violent and tolerant attitude of Mahāvīra helped much in the development of the nonabsolutistic principle of Anekāntavāda. In Sūtrakritānga, he
