Anumana or Inference:
- This word is derived from two Sanskrit words, 'Anu' means after and 'Mana' means measurement. So it means measuring after something.
- Anumana is the knowledge after proof.
- Anumana is a means of knowledge or one of the six types of Pramans in Indian Philosophy.
Gautama has classified anumana into three,
| Anumana | Definition |
| Puvovat anumana |
Here we infer the unperceived effect from a perceived cause. Example: After the appearance of the dark cloud, we can infer future rain |
| Sesvat anuman |
Here we infer the unperceived cause from a perceived effect. Example: To infer rain in the past by perceiving muddy water in the pond |
|
Samanayatodrasta anumana |
Here we infer not based on causal relation but the experience of uniformity Example: To see the changing position of the moon we can infer about its motion |
Based on Vyapti, the inference can also be classified into three,
| Inference | Definition |
| Kevalanvayi |
In this anumana, vyâpti between the middle and the major term is derived from a uniform agreement in presence alone. Example: All knowable objects are nameable; |
| Kevalavyatireki |
In this anumana, vyapti between the middle and the major is derived from a uniform agreement in absence alone. Example: What is not different from other elements has no smell; |
| Anvayavyatireki |
Here, the middle term in inference is both positively and negatively related to the major term. Example: All smoky objects are fiery; No non-fiery object is smoky; |
Therefore, option 2 is the correct answer.
