The Marigolds and the Missing Gardener: A Nyaya Debate
At a Sanskrit school's debate session, a student argues that a recently vacated plot of land has a gardener. The student's inference is: 'This plot has a gardener, because it has flowering marigolds.' The student offers the five-membered Nyaya form: 'This plot has a gardener; because it has flowering marigolds; whatever has flowering marigolds has a gardener, like the school flowerbed; this plot has flowering marigolds; therefore this plot has a gardener.' An opponent objects that a wild hillside two kilometres away has self-seeded marigolds and no gardener, and that the plot's marigolds may have self-seeded after the previous gardener left. The teacher asks the class to evaluate the inference using Nyaya categories: paksha, sadhya, hetu, vyapti, sapaksha, vipaksha, and the fallacies asiddha, savyabhicara, and viruddha. The class must decide whether the conclusion is established and how the inference could be repaired.
1. Identify the five members of the inference and the paksha, sadhya, and hetu. State the vyapti that the inference needs.

Five members:
- Pratijna (thesis): 'This plot has a gardener.'
- Hetu (reason): 'Because it has flowering marigolds.'
- Udaharana (example): 'Whatever has flowering marigolds has a gardener, like the school flowerbed.'
- Upanaya (application): 'This plot has flowering marigolds.'
- Nigamana (conclusion): 'Therefore this plot has a gardener.'
Paksha: the recently vacated plot under discussion. Sadhya: having a gardener. Hetu: having flowering marigolds.
Vyapti needed: wherever there are flowering marigolds, there is a gardener; the hetu must be pervaded by the sadhya. The school flowerbed is offered as a sapaksha, a similar example where both hetu and sadhya are present. The wild hillside is a potential vipaksha, a dissimilar example where the sadhya is absent.
2. Classify the defect raised by the opponent. Is it asiddha, savyabhicara, or viruddha? Explain using sapaksha and vipaksha.

The defect is savyabhicara, the deviating hetu.
A hetu is savyabhicara when it is not invariably accompanied by the sadhya: it occurs in a vipaksha, a case where the sadhya is absent. The wild hillside has flowering marigolds but no gardener. So the hetu 'has flowering marigolds' is present where the sadhya 'has a gardener' is absent. The required vyapti therefore fails.
It is not asiddha, because the presence of flowering marigolds in the paksha is not in doubt; the opponent does not deny that the plot has marigolds. It is not viruddha, because the hetu does not prove the opposite of the sadhya; it does not establish that the plot has no gardener. It merely fails to establish that it has one.
The school flowerbed is a genuine sapaksha, but one sapaksha cannot establish universal vyapti when a vipaksha is available. The udaharana therefore overgeneralizes from a single favourable example.
3. Repair the inference so that it is a valid Nyaya inference. State the revised hetu, the vyapti, and the sapaksha/vipaksha check. Does the original conclusion survive?
Read the worked answer
A repair must strengthen the hetu so that it is invariably accompanied by the sadhya. For example, revise the hetu to: 'This plot has recently watered, weed-free marigold beds planted in straight rows.'
Revised vyapti: wherever there are recently watered, weed-free marigold beds in straight rows, a gardener tends them. The school flowerbed can serve as sapaksha: it has such beds and a gardener. The wild hillside serves as vipaksha: it lacks such cultivated beds and lacks a gardener, so it no longer counts against the vyapti.
Check the paksha: one must first establish that the plot actually has recently watered, weed-free beds in straight rows. If it does, the hetu is present and the inference is strong. If it does not, the revised hetu is asiddha, unproved.
The original conclusion does not survive on the original hetu, because the wild hillside defeats the vyapti. With the stronger hetu, a conclusion about a gardener can be supported, but only if the new evidence about cultivation is independently verified.
