Kaṇāda

Kaṇāda (also Kaśyapa, Ulūka, Kaṇabhuj) is the sage traditionally credited with founding the Vaiśeṣika school of Indian philosophy and with composing the Vaiśeṣika Sūtras, its root text. His dates are unknown — estimates range from the sixth to the first century BCE — and he is known only through legend and through the Sūtras, which were expanded and reorganised over time.

The name

Kaṇāda means “particle-eater” or “grain-eater”. One explanation is ascetic: he lived on the grains left in the fields after harvest, like a bird. Another is philosophical: he “ate” — analysed — the world into its smallest particles, kaṇas. A third name, Ulūka (“owl”), gave his school the nickname aulūkya-darśana, “the owl’s philosophy”, used mockingly by opponents; a legend says Śiva appeared to him in the form of an owl and taught him the system.

The teaching

The Vaiśeṣika Sūtras, in ten books, open: “Now, therefore, we shall explain dharma. Dharma is that from which comes prosperity and the highest good. The authority of the Veda comes from its being the word of that (dharma or God).” They then claim that the highest good results from knowledge of six categories — substance, quality, action, universal, particularity and inherence — by their similarities and differences.

The Sūtras enumerate the nine substances, define qualities and actions, discuss the nature of causation and of the self (inferred from breathing, the opening and closing of the eyes, life, the movement of the mind, the operations of the senses, pleasure, pain, desire, aversion and effort), and argue for the eternal, imperceptible atoms of earth, water, fire and air. They explain natural phenomena — the upward movement of fire, the sideways movement of wind, the falling of bodies by weight, the flow of liquids, the rising of sap in plants, the magnet attracting iron — in terms of the categories and of the unseen force (adṛṣṭa). See Vaiśeṣika.

Legacy

Kaṇāda’s system was reworked by Praśastapāda in the sixth century CE and later merged with Nyāya. In modern India, he has become a national hero of science, often presented as the discoverer of the atom centuries before the Greeks — a claim that reflects pride more than evidence, since the dating of both traditions is uncertain and their atomisms differ greatly. What is certain is that he founded a sophisticated, original analysis of reality whose categories shaped Indian thought for two millennia.
