Philosophical Context

In classical Indian logic and the Nyāya-Vaiśeṣika system:

• The term apadeśa refers to a “reason” or hetu used in inferential 
• knowledge (anumāna).
• Anapadeśa, then, is a case where no valid reason applies—either
• because the proposed reason is unknown, contradictory
• (viruddha), or unproven (asiddha) with respect to the property
• to be inferred

  .
• For example, in the Vaiśeṣika Sūtra III-1-15, it is stated that a 
• mark or “liṅga” that differs in one or both aspects from the standard
• cannot be accepted as a valid inferential sign; this establishes the 
• concept of anapadeśa as a logical fallacy or absence of a 
• reliable basis
