Position summary
Ruegg is one of the foremost Western scholars of Indian and Tibetan Buddhist philosophy, known for meticulous philological work and for sensitivity to the philosophical substance of the texts he studies. On the Svātantrika-Prāsaṅgika distinction, his view is that it turns on several interrelated criteria, all of them converging on the status of conventional reality (saṃvṛti/vyavahāra). He treats the distinction as a dynamic set of philosophical and methodological issues, not a frozen dichotomy between two immutable doctrinal positions. Handled with care and historical awareness, he argues, it keeps its descriptive, taxonomic, analytical, and heuristic value — even though the formal nomenclature is unattested in Indian sources.
Hermeneutical approach
Ruegg works across two registers at once: traditional Indo-Tibetan scholastic positions and modern academic method. He reads Sanskrit and Tibetan sources in the original and takes the internal philosophical logic of Indian and Tibetan thinkers seriously. Throughout, he keeps a careful line between the emic level of analysis (tradition-internal, synchronic) and the etic (historical, comparative). He will draw on comparative philosophy — quantum-physics analogies, Wittgensteinian connections — but he is candid about how far such comparisons can reach. His engagement with the tathāgatagarbha, with gotra, and with Madhyamaka runs across decades.
Key claims
- The terms svātantrika and prāsaṅgika are Tibetan codifications, not Indian technical terms (ruegg-svat-pras-2006)
- The distinction involves six (or more) interrelated criteria, all concerning the status of saṃvṛti (ruegg-svat-pras-2006)
- Candrakīrti was largely ignored in Indian Buddhism for centuries after his time (ruegg-svat-pras-2006)
- Apophatic and cataphatic descriptions in Madhyamaka may be understood through an indeterminacy/complementarity model (ruegg-svat-pras-2006)
- The distinction is not a “simple ready-made tool” but retains analytical and heuristic usefulness (ruegg-svat-pras-2006)
