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.

Lectures on the Cārvāka/Lokāyata (Part II) :
Some Common Misrepresentations ExaminedThis lecture refutes common misconceptions surrounding Cārvāka/Lokāyata philosophy. It demonstrates that Cārvākas did not reject inference entirely, but accepted empirical reasoning while rejecting transcendent claims. Furthermore, it dispels the caricature of Cārvākas as unrestrained sensualists, showing that orthodox critics misrepresented their rejection of asceticism and ritualism as moral depravity.

Lectures on the Cārvāka/Lokāyata (Part I) :
An Overview of the Cārvāka/Lokāyata MaterialismThis lecture provides an overview of philosophical materialism, examining its foundational tenets and unique emergence within ancient India. It traces the development of Cārvāka/Lokāyata as a systematized, indigenous school, contrasting its empirical epistemology, materialist ontology, and anti-ascetic ethics with Presocratic Greek thought, pre-Cārvāka proto-materialism, and various regional folk-tradition cults.

Jayanta Bhaṭṭa’s Inconsistencies and Misrepresentations
This section analyzes Nyāya scholar Jayanta Bhaṭṭa’s contradictory polemics against Cārvāka epistemology in the Nyāyamañjarī. By shifting inconsistently between the base sūtra text and Udbhaṭa’s commentary, Jayanta obscured the Cārvāka acceptance of practical, worldly inference, misrepresenting their nuanced empirical position as absolute agnostic skepticism to undermine their materialist philosophy in debate.

The Base Text and Its Commentaries
Problems of Representing and Understanding the Cārvāka/LokāyataAncient Indian philosophical sūtras are terse aphorisms requiring balanced reading alongside commentaries. Relying solely on either literal texts or commentaries leads to misunderstandings. Opponents of Cārvāka/Lokāyata like Jayanta Bhaṭṭa and Hemacandra failed to maintain this crucial balance, resulting in misrepresentations of materialist doctrines in their polemical works.

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.

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.
