Panini was born in Shalatula, a town near to Attock on
the Indus river in present day Pakistan. The dates given for Panini are pure
guesses. Experts give dates in the 4th, 5th,
6th and 7th century BC and there is also no agreement
among historians about the extent of the work which he undertook. What is in
little doubt is that, given the period in which he worked, he is one of the most
innovative people in the whole development of knowledge. We will say a little
more below about how historians have gone about trying to pinpoint the date when
Panini lived.
Panini was a Sanskrit grammarian who gave a comprehensive and
scientific theory of phonetics, phonology, and morphology. Sanskrit was the
classical literary language of the Indian Hindus and Panini is considered the
founder of the language and literature. It is interesting to note that the word
"Sanskrit" means "complete" or "perfect" and it was thought of as the divine
language, or language of the gods.
A treatise called Astadhyayi (or Astaka ) is
Panini's major work. It consists of eight chapters, each subdivided into quarter
chapters. In this work Panini distinguishes between the language of sacred texts
and the usual language of communication. Panini gives formal production rules
and definitions to describe Sanskrit grammar. Starting with about 1700 basic
elements like nouns, verbs, vowels, consonants he put them into classes. The
construction of sentences, compound nouns etc. is explained as ordered rules
operating on underlying structures in a manner similar to modern theory. In many
ways Panini's constructions are similar to the way that a mathematical function
is defined today. Joseph writes in [2]:-
[Sanskrit's] potential for scientific use was greatly enhanced as a result of the thorough systemisation of its grammar by Panini. ... On the basis of just under 4000 sutras [rules expressed as aphorisms], he built virtually the whole structure of the Sanskrit language, whose general 'shape' hardly changed for the next two thousand years. ... An indirect consequence of Panini's efforts to increase the linguistic facility of Sanskrit soon became apparent in the character of scientific and mathematical literature. This may be brought out by comparing the grammar of Sanskrit with the geometry of Euclid - a particularly apposite comparison since, whereas mathematics grew out of philosophy in ancient Greece, it was ... partly an outcome of linguistic developments in India.
Joseph goes on to make a convincing argument for the algebraic
nature of Indian mathematics arising as a consequence of the structure of the
Sanskrit language. In particular he suggests that algebraic reasoning, the
Indian way of representing numbers by words, and ultimately the development of
modern number systems in India, are linked through the structure of language.
Panini should be thought of as the forerunner of the modern
formal language theory used to specify computer languages. The Backus Normal
Form was discovered independently by John Backus in 1959, but Panini's
notation is equivalent in its power to that of Backus and has many similar properties.
It is remarkable to think that concepts which are fundamental to today's
theoretical computer science should have their origin with an Indian genius
around 2500 years ago.
At the beginning of this article we mentioned that certain
concepts had been attributed to Panini by certain historians which others
dispute. One such theory was put forward by B Indraji in 1876. He claimed that
the Brahmi numerals developed out of using letters or syllables as numerals.
Then he put the finishing touches to the theory by suggesting that Panini in the
eighth century BC (earlier than most historians place Panini) was the first to
come up with the idea of using letters of the alphabet to represent numbers.
There are a number of pieces of evidence to support Indraji's
theory that the Brahmi numerals developed from letters or syllables. However it
is not totally convincing since, to quote one example, the symbols for 1, 2 and
3 clearly do not come from letters but from one, two and three lines
respectively. Even if one accepts the link between the numerals and the letters,
making Panini the originator of this idea would seem to have no more behind it
than knowing that Panini was one of the most innovative geniuses that world has
known so it is not unreasonable to believe that he might have made this step
too.
There are other works which are closely associated with the
Astadhyayi which some historians attribute to Panini, others attribute to
authors before Panini, others attribute to authors after Panini. This is an area
where there are many theories but few, if any, hard facts.
We also promised to return to a discussion of Panini's dates.
There has been no lack of work on this topic so the fact that there are theories
which span several hundreds of years is not the result of lack of effort, rather
an indication of the difficulty of the topic. The usual way to date such texts
would be to examine which authors are referred to and which authors refer to the
work. One can use this technique and see who Panini mentions.
There are ten scholars mentioned by Panini and we must assume
from the context that these ten have all contributed to the study of Sanskrit
grammar. This in itself, of course, indicates that Panini was not a solitary
genius but, like Newton, had "stood on the shoulders of
giants". Panini must have lived later than these ten but this is absolutely no
help in providing dates since we have absolutely no knowledge of when any of
these ten lived.
What other internal evidence is there to use? Well of course
Panini uses many phrases to illustrate his grammar any these have been examined
meticulously to see if anything is contained there to indicate a date. To give
an example of what we mean: if we were to pick up a text which contained as an
example "I take the train to work every day" we would know that it had to have
been written after railways became common. Let us illustrate with two actual
examples from the Astadhyayi which have been the subject of much study.
The first is an attempt to see whether there is evidence of Greek influence.
Would it be possible to find evidence which would mean that the text had to have
been written after the conquests of Alexander the Great? There is a little
evidence of Greek influence, but there was Greek influence on this north east
part of the Indian subcontinent before the time of Alexander. Nothing conclusive
has been identified.
Another angle is to examine a reference Panini makes to nuns.
Some argue that these must be Buddhist nuns and therefore the work must have
been written after Buddha. A nice argument but there is a counter argument which
says that there were Jaina nuns before the time of Buddha and Panini's reference
could equally well be to them. Again the evidence is inconclusive.
There are references by others to Panini. However it would
appear that the Panini to whom most refer is a poet and although some argue that
these are the same person, most historians agree that the linguist and the poet
are two different people. Again this is inconclusive evidence.
Let us end with an evaluation of Panini's contribution by
Cardona in [1]:-
Panini's grammar has been evaluated from various points of view. After all these different evaluations, I think that the grammar merits asserting ... that it is one of the greatest monuments of human intelligence.
