In this fourth chapter, Somānanda and Utpaladeva engage logical and philosophical works that exerted tremendous influence in the Indian subcontinent in its premodernity. Among the authors and schools addressed by Somānanda in this chapter are the Buddhist Epistemologists, and Dharmakīrti in particular; the Hindu school of hermeneutics, i.e., the Mīmāṃsā; the Hindu realist schools of the logic- and debate-oriented Nyāya and their ontologically-oriented partners, the Vaiśeṣika; and the Hindu, dualist Sāṃkhya and Yoga schools.
Throughout this chapter, Somānanda endeavors to explain his brand of Śaivism philosophically. Somānanda challenges his philosophical interlocutors with a single over-arching argument: he suggests that their views cannot cohere--they cannot be explained logically--unless their authors accept the Śaiva non-duality for which he advocates. The argument he offers, despite its historical influence, remains virtually unstudied. The Ubiquitous Śiva Volume II offers the first English translation of Chapter Four of the Śivadṛṣṭi and Śivadṛṣṭivṛtti along with an introduction and critical edition.
