Age of the Sutra

The second part of our series on philosophy in India examines the "age of the sūtra." The sūtra (literally "thread") was a genre of writing in which ideas were set forth in brief, aphoristic form. Various sūtras were taken as authoritative and foundational for numerous schools of Indian thought, which devoted further commentaries to the sūtras. Historically, these episodes cover the period in which most of the sūtras and initial commentaries were written, that is, approximately the first several centuries CE (though some sūtras are older, and the commentaries were written over many centuries). At this time, we see numerous intellectual traditions emerge: Sāṃkhya, Yoga, Nyāya, Vaiśeṣika, Mīmāṃsā, Vedānta, and Cārvāka. These episodes cover the main developments and disputes found in the sūtras and commentaries, with a focus on such issues as the self and mind's relation to the material world, philosophy of language, the efficacy of ritual, and the sources of human knowledge. Look out for interviews with experts on this period, including Monima Chadha, Francis Clooney, Elisa Freschi, V.N. and Ujjwala Jah, and Philipp Maas.
