_As_ meant originally _to breathe_, and from it we have _asu_, breath, spirit, life, also _âs_ the mouth, Latin _ôs_, _ôris_. By constant wear and tear this root _as_, to breathe, had first to lose all signs of its original material character, before it could convey that purely abstract meaning of existence, without any qualification, which has rendered to the higher operations of thought the same service which the nought, likewise the invention of Indian genius, has to render in arithmetic. Who will say how long the friction lasted which changed _as_, to breathe, into _as_, to be? And even a root _as_, to breathe, was an Aryan root, not Semitic, not Turanian. It possessed an historical individuality--it was the work of our forefathers, and represents a thread which unites us in our thoughts and words with those who first thought for us, with those who first spoke for us, and whose thoughts and words men are still thinking and speaking, though divided from them by thousands, it may be by hundreds of thousands of years. This is what I call _history_ in the true sense of the word, something really worth knowing, far more so than the scandals of courts, or the butcheries of nations, which fill so many pages of our Manuals of History. And all this work is only beginning, and whoever likes to labor in these the most ancient of historical archives will find plenty of discoveries to make--and yet people ask, What is the use of learning Sanskrit? We get accustomed to everything, and cease to wonder at what would have startled our fathers and upset all their stratified notions, like a sudden earthquake. Every child now learns at school that English is an Aryan or Indo-European language, that it belongs to the Teutonic branch, and that this branch, together with the Italic, Greek, Celtic, Slavonic, Iranic, and Indic branches, all spring from the same stock, and form together the great Aryan or Indo-European family of speech. But this, though it is taught now in our elementary schools, was really, but fifty years ago, like the opening of a new horizon of the world of the intellect, and the extension of a feeling of closest fraternity that made us feel at home where before we had been strangers, and changed millions of so-called barbarians into our own kith and kin. To speak the same language constitutes a closer union than to have drunk the same milk; and Sanskrit, the ancient language of India, is substantially the same language as Greek, Latin, and Anglo-Saxon. This is a lesson which we should never have learned but from a study of Indian language and literature, and if India had taught us nothing else, it would have taught us more than almost any other language ever did.
