Inference as Pramāṇa
Anumāna ('inferring,' 'reasoning after the fact') is the second recognized pramāṇa in Vishishtadvaita. It is the process of inferring the presence of an unobserved object or fact from observed evidence, through a known relationship (vyāpti — invariable concomitance) between the two.
Classic Structure
The classic structure of anumāna in Indian logic: pakṣa (the subject of inference) — 'The hill has fire'; hetu (the reason) — 'because it has smoke'; vyāpti (invariable concomitance, the major premise) — 'wherever there is smoke there is fire'; dṛṣṭānta (example) — 'as in a kitchen.' This structure is applied throughout Indian philosophical debate.
Use in Vishishtadvaita
Rāmānuja uses anumāna to establish that Brahman is the cause of the universe (from the evidence of the universe's design and order), that the soul is distinct from the body (from the evidence of different states of the same person), and that the jīva's knowledge is genuine even in bondage. Anumāna supports and extends what pratyakṣa observes.
Limitations
Anumāna cannot establish the specific nature of Brahman, the details of karma and liberation, or the means of mokṣa. For these, śabda-pramāṇa (scriptural testimony) is indispensable. The role of anumāna in theology is primarily to demonstrate coherence and resolve contradictions — the substantive content comes from śāstra.

Anumānam — Inference as a Means of Valid Knowledge
Anumānam (Sanskrit: anu = after/following + māna = measure/knowledge; 'knowledge that follows') is the second of the three primary pramāṇas (valid means of knowledge) in Indian philosophical epistemology — the process of arriving at knowledge through logical inference from a visible mark (liṅga) to an invisible conclusion (sādhya).
Classic Example: 'There is fire on the mountain' — inferred from seeing smoke. The smoke (observable mark) is the liṅga; fire (unobservable) is the sādhya. The logical bridge is the invariable relationship (vyāpti): wherever there is smoke, there is fire.
Structure of an Inference (Nyāya system):
- Pratijñā — statement ('The mountain has fire')
- Hetu — reason ('Because it has smoke')
- Udāharaṇa — example ('Like a kitchen')
- Upanaya — application ('The mountain has smoke')
- Nigamana — conclusion ('Therefore the mountain has fire')
Role in Viśiṣṭādvaita: Anumānam is valuable but limited — it can only work from what the senses have observed (its vyāpti requires empirical backing). For transcendent truths (the nature of Brahman, the soul's liberation), anumānam cannot reach — only śabda pramāṇam (Vedic testimony) can. 'Inference is a good servant of śabda but a poor replacement for it in matters beyond sense-experience.'
The Three Pramāṇas Together: Pratyakṣa (perception) → anumānam (inference from perception) → śabda (Vedic testimony transcending perception) — these three together give complete valid knowledge. Rāmānuja accepts all three, in this hierarchy.
