Studies on the Doctrine of Trairūpya presents a rigorous textual and logical analysis of the foundational rule of inference (anumāna) in classical Indian logic. Written by Indologist Claus Oetke, this monograph investigates the historical and structural mechanics of the trairūpya (the "three characteristics of a valid logical reason" or hetu). The doctrine dictates that a valid middle term must strictly satisfy three criteria: presence in the subject (pakṣadharmatvam), presence in similar instances (sapakṣe sattvam), and complete absence from dissimilar instances (vipakṣe cāsatvam)
