Abstract

The article discusses Bhāviveka’s Prajñāpradīpavṛtti and Avalokitavrata’s Prajñāpradīpaṭīkā commentaries on the “not without a cause” (nāpy ahetutaḥ) alternative of Nāgārjuna’s Mūlamadhyamakakārikā 1.1ab, from which it emerges that at least two distinct theories of causality can be attributed to the Lokāyata school. The first one is a physicalist theory that confines all causal relations within the sphere of material elements and is assimilated to accidentalism. The second one is a naturalist theory that attributes causal power to inner nature (svabhāva). The paper discusses the theoretical differences between these two approaches, considers Bhāviveka’s and Avalokitavrata’s counter-arguments and concludes that some of the conjectures that modern scholars have put forward on the relation between svabhāvavāda, accidentalism and Lokāyata should be revised.
