* As of now, I have not been introduced to a seven membered and eleven membered
syllogism. So the five membered syllogism is what I know. On a lighter note, I
could not get this thing about syllogism properly in my twenties (I am nearly 40
now) in English. Now, I seem to understand tarka in Sanskrit :-).

So, if one shows that the symptom exists, and symptom and the
sAdhya, the truth to be established, co-exist in an anvayi-vyatireki fashion,
one has proven one's hypothesis.

Here what is referred as sadhya is, if i correctly understand, the "Udaharana"?
i.e the case of kitchen fire & smoke taken as example for the ultimate
deduction?

* The sAdhya is contained in the hypothesis: that is, the agnimatvam of the
mountain (fire on mountain is the truth to be established).

I would try to further understand and refresh the concept in the example given
in Ramana maharishi episode

Thank you very much again, for refreshing my memories on logic and especially
for the way Anvayi-vyatireki has been explained

Shriman, the concept has been explained in a crystal clear manner and I am
extremely thankful to you. Decades back when I was in school studying principles
of western logic, we were given introduction of Indian Logic also.

In any philosophical discourse, I use to come across mention of Anvaya Vyatireka
logic.  Although what is explained was clear to me, the matter explained
vis.a.vis Anvaya Vyatireka was elusive.

After the five steps based deduction, I find the crux of the logic is made
crystal clear here, i.e

"First anvaya: Wherever there is smoke, there ought to be fire (as in the
kitchen); vyatireka: where there is no fire, there ought to be no smoke (as in a
lake or a river)"

I remember vaguely the five steps through which the inference is made was
explained to us as "Five membered syllogism".  I vaguely again remember of seven
membered and eleven membered syllogism. I am not sure.
