Development of Logic in India: Significance of ‘The Duologue between Pāyāsi and Kassapa’ (“Long Discourses”)
The “Duologue of King Pāyāsi” highlights a pivotal shift in early Indian philosophy toward formal logic. Moving beyond the Kaṭha Upaniṣad’s reliance on scriptural authority (śabda) to prove an afterlife, both Buddhist and Jain versions pits empirical perception—observation and experiment—against argument by analogy. Together, these texts illustrate the early evolution of epistemological methods.

From Proto-materialism to Materialism:
The Indian ScenarioShadows of ancient doubt linger beneath the sacred canonical texts. Long before modern skepticism arose, Indian thinkers dismantled the afterlife, challenged scriptural inerrancy, and asserted that consciousness dies with the flesh. Step past orthodox dogma to explore the suppressed, rationalist roots of pre-Cārvāka thought and the sharp materialist tradition.

Epistemological Parallels :
Cārvāka and David HumeComparing David Hume and Cārvāka, Bina Gupta examines skepticism across Eastern and Western philosophy. The essay explores how both traditions treat perception as fundamental, rejecting dogmatic metaphysics and necessary causal connections. However, Gupta highlights key differences: Cārvāka adopts radical materialism, whereas Hume’s epistemological framework leads to a more nuanced, mitigated skepticism.

Tattvopaplavavāda of Jayarāśi and its Alleged Relation to the Cārvāka/Lokāyata
Ramkrishna Bhattacharya challenges the classification of Jayarāśibhaṭṭa’s Tattvopaplava-siṁha as a Cārvāka text. Highlighting internal textual evidence, he argues Jayarāśi rejected all pramāṇas and claimed intellectual superiority over Bṛhaspati. Rather than endorsing materialism, Jayarāśi established a distinct, radical doctrine—tattvopaplavavāda—aimed at upsetting all philosophical principles and refuting all opposing views.

Udbhaṭa’s Revisionism and Nyāya-Style Exegesis
This essay analyzes Bhaṭṭodbhaṭa’s controversial commentary on the Cārvākasūtra. Utilizing Nyāya terminology and linguistic reinterpretations, Udbhaṭa departed from traditional monistic materialism toward a dualist stance on body and consciousness. His revisionist exegesis was heavily cited by opponents like Jayanta Bhaṭṭa to critique materialist philosophy in Indian debate.

Commentators on the Cārvākasūtra:
A Critical SurveyThis critical survey examines thirty surviving commentary fragments of the lost Cārvākasūtra. It analyzes four key commentators—Kambalāśvatara, Purandara, Aviddhakarṇa, and Udbhaṭa—highlighting how late commentators introduced Nyāya-Vaiśeṣika concepts, diverged from classical monist materialism into dualist interpretations, and maintained perception as the primary pramāṇa while accepting verifiable empirical inference.

The Ontology and Epistemology of the Cārvāka/Lokāyata
Ramakrishna Bhattacharya outlines Cārvāka four-elemental ontology and perception-based epistemology, examining how commentators defended these views. While Purandara and Aviddhakarṇa affirmed empirical inference, revisionists like Udbhaṭa introduced Nyāya categories and dualism. Bhattacharya argues that forced glosses moving away from the author’s original intent represent hermeneutical inconsistencies rather than genuine internal development.

What the Cārvākas Originally Meant:
More on the Commentators on the CārvākasutraThis paper reviews the methodology of reconstructing the lost Cārvāka/Lokāyata text tradition from surviving fragments. By evaluating commentators like Purandara, Aviddhakarṇa, and Udbhaṭa, it contrasts faithful explications of empirical inference with radical, inconsistent innovations. It argues that historicist intent must precede studying later accretions to accurately understand ancient Indian materialism.

Lokāyata Materialism:
Classification of Source MaterialsThis paper analyzes five commentators of the lost Cārvākasūtra—Aviddhakarṇa, Udbhaṭabhaṭṭa, Kambalāśvatara, Purandara, and Bhāvivikta. It contrasts traditional, literal explications with Udbhaṭa’s revisionist interpretations, which introduced Nyāya-Vaiśeṣika categories and near-idealist stances. Despite these divergent developments, all commentators consistently upheld the foundational Cārvāka principle of the primacy of empirical perception.

Elements of Materialism in the Nyaya and Vaisesika Philosophy
Founded by Gotama and Kaṇāda, the Nyāya and Vaiśeṣika systems contain significant materialist foundations. Nyāya emphasizes empirical logic and sensory perception as primary tools for acquiring reliable knowledge. Meanwhile, Vaiśeṣika introduces early atomism, proposing that indivisible, eternal physical atoms interact in space under natural laws to construct all observable reality and consciousness.

Materialism in India: A Synoptic View
Cārvāka, or Lokāyata, emerged around the sixth century CE as India’s only systematized materialist school, featuring formal sūtras and commentaries. Rejecting supernaturalism, immortal souls, and ritualism, it prioritized matter, perception, and empirical inference. Historical texts lost by the fourteenth century led opponents to misrepresent its teachings as unrefined, hedonistic, and promiscuous.
