Abstract
It has been a matter of great debate among scholars of religious studies and philosophers of religion whether we can speak about religious truth. This paper traces Wittgenstein's and Nagarjuna's philosophical ways of thinking concerning language which tries to transmit the truth to us. Though the religious and cultural backgrounds are different for Wittgenstein and Nagarjuna, both of them teach us in their unique and profound ways that even the most religious people cannot speak directly about religious truth itself, but they can indirectly indicate it. In short, religious language has a "function" that indirectly indicates religious truth to us.
