 However, the Nyāya-Vaiśeṣika philosopher might bite the bullet on this challenge. She might say that not all cases of explanatory regress are bad, so there is no harm in positing a beginningless chain of causes and effects. In response, Śrīharṣa is happy to grant that not all explanatory regresses are vicious. But if an explanatory regress involving occasionality and causal relevance is to get off the ground, we would have to cite at least one case where the occasionality of a putative effect e is in fact explained by the causal relevance of a distinct entity c. The Nyāya-Vaiśeṣika philosopher is yet to show that; in fact, she is appealing to the infinite explanatory regress in order to establish that claim.
