Vaisheshika's Legacy: An Ancient Physics Still Read

Kanada's atomism is regularly set beside Democritus and Leucippus as one of the ancient world's few fully worked out theories that matter is built from indivisible, indestructible units, arrived at independently of Greek philosophy and on different argumentative grounds entirely; where Greek atomism reasoned from the logic of divisibility, Vaisheshika reasoned from a systematic classification of the categories that make any object what it is, arriving at atoms as the smallest unit reality's structure requires. Vaisheshika never survived as an independent living school; its distinctive vocabulary and its doctrine of adrishta, the unseen moral force carrying the effects of past action forward into future events, were absorbed into the merged Nyaya Vaisheshika synthesis and are now studied as part of that combined tradition rather than as Kanada's system standing alone. That absorption preserved rather than erased the content: the Encyclopedia of Indian Philosophies traces Vaisheshika's categorial scheme forward through the syncretic school into Navya Nyaya's formal logic, still an active subject of academic study and, in more limited circles, of traditional Sanskrit scholarly training in India today. Kanada's own biography remains almost entirely unrecoverable, a name attached to a text rather than a documented life, but the categories that text set out, substance, quality, action, generality, particularity and inherence, continued to organize Indian philosophical argument about the physical world for well over a thousand years after whoever first wrote them down.
