Note 297 — Chapter XII · THE JAIMINI-DARŚANA.
Edward B. (Edward Byles) Cowell translation
The Nyáya holds that wrong knowledge is produced by a "defect," as jaundice, &c., in the eye, and right knowledge by a guṇa or "virtue" (as the direct contact of the healthy organ with a true object), or by the absence of a "defect."
