 Nyāya-Vaiśeṣika atomism developed in constant dialogue with other Indian philosophical schools: in a context where Buddhism offered a compelling narrative of personal salvation through detachment from the unrealities of the experienced world, some Hindu philosophers responded by bolstering their case for the realism of the experienced world, and real atomic substances were invoked to explain both mental and physical events (Ganeri 2011, 167–8). The idea that experienced properties inhere in real external substances was used to account for intersubjective agreement about the external world.
