My chief object, therefore, as Professor of Comparative Philology at Oxford, will be to treat the classical languages under that new aspect which they have assumed, as viewed by the microscope of Curtius and Corssen, rather than by the telescope of Bopp, Pott, and Benfey. I shall try not only to give results, but to explain what is far more important, the method by which these results were obtained, so far as this is possible without, for the present at least, presupposing among my hearers a knowledge of Sanskrit. Sanskrit certainly forms the only sound foundation of Comparative Philology, and it will always remain the only safe guide through all its intricacies. A comparative philologist without a knowledge of Sanskrit is like an astronomer without a knowledge of mathematics. He may admire, he may observe, he may discover, but he will never feel satisfied, he will never feel certain, he will never feel quite at home. I hope, therefore, that, besides those who attend my public lectures, there will be at least a few to form a private class for the study of the elements of Sanskrit. Sanskrit, no doubt, is a very difficult language, and it requires the study of a whole life to master its enormous literature. Its grammar, too, has been elaborated with such incredible minuteness by native grammarians, that I am not surprised if many scholars who begin the study of Sanskrit turn back from it in dismay. But it is quite possible to learn the rules of Sanskrit declension and conjugation, and to gain an insight into the grammatical organization of that language, without burdening one’s memory with all the phonetic rules which generally form the first chapter of every Sanskrit grammar, or without devoting years of study to the unraveling of the intricacies of the greatest of Indian, if not of all grammarians,--Pâṇini. There are but few among our very best comparative philologists who are able to understand Pâṇini. Professor Benfey, whose powers of work are truly astounding, stands almost alone in his minute knowledge of that greatest of all grammarians. Neither Bopp, nor Pott, nor Curtius, nor Corssen, ever attempted to master Pâṇini’s wonderful system. But a study of Sanskrit, as taught by European grammarians, cannot be recommended too strongly to all students of language. A good sailor may, for a time, steer without a compass, but even he feels safer when he knows that he may consult it, if necessary; and whenever he comes near the rocks,--and there are many in the Aryan sea,--he will hardly escape shipwreck without this magnetic needle.[8]
