 While Caraka-saṃhitā provides only one illustration of its canonical syllogism, the earliest extant commentary on the Nyāya-sūtra, called the Nyāya-bhāṣya (Commentary on logic), has passages in its commentary on NS 1.1.33–39, which permit the reconstruction of two analogical syllogisms, corresponding to those using similarity and using dissimilarity discussed above. The commentary, attributed to Vātsyāyana (fifth ce), also known as Pakṣilasvāmin, explicitly distinguishes the syllogisms as one based on similarity (sādharmya) and the other based on dissimilarity (vaidharmya) discussed earlier. (For details, see Gillon 2020.) The analogical syllogism based on similarity differs but slightly from the syllogism found in the Caraka-saṃhitā.
