Panini's grammar is the earliest scientific grammar in the world, the earliest extant grammar of any language, and one of the greatest ever written. It was the discovery of Sanskrit by the West, at the end of the 18th century, and the study of Indian methods of analyzing language that revolutionized our study of language and grammar, and gave rise to our science of comparative philology ... The study of language in India was much more objective and scientific than in Greece or Rome. The interest was in empirical investigation of language, rather than philosophical and syntactical. Indian study of language was as objective as the dissection of a body by an anatomist.
