I think - "tarka" is an approximation as for as my understanding goes. Tarka stands for all most all meanings that u hv shown. regards, shrivara

Dear Indology Colleagues,

I was wondering two questions:

(1) If Sanskrit presents a single term with the ideological baggage of the Greek Logos: (a term that stands for thought, reason, word/language, opinion)

(2) If the answer to (1) is yes, if such a term is of special importance for any particular school of thought.

My impression is that while Indian languages have many words for reason or knowledge, opinion and thought, and words for linguistic items such as "word," these are often different words.

Thanks in advance!
