There is, therefore, ample scope and a peremptory demand for both methods of lingual development. The New Scientific Language herein suggested would be universal within the limit within which Science itself is universal. But there is another sphere within which Science, born of the Intellect, has only a subordinate sway, and in which instinct, or that faculty which, in the higher aspect of it, we denominate Intuition, is supreme. This faculty has operated as instinct in the first stage of the growth of Language, the Natural or Instinctual; it should now give place to the Intellect, in the second stage, the Scientific; after which it should regain its ascendency as Intuition, in the final finish and perfectionment of the Integral Speech of Mankind, the Artistic. Such a Language would be, to all other Languages, precisely what a unitary Science would be to all the special Sciences; and we have seen how it might happen that the same discovery should furnish both the Language and the Science. Without rudely displacing any existing Language, it would, besides filling its own central sphere of uses, furnish a rallying point of unity between them all. It would ally them to itself, not by the destruction of their several individualities, but by developing the genius of each to the utmost. It would enrich them all, by serving as the common interpreter between them, until each would attain something of the powers of all, or at least the full capacity for availing itself of the aid of all others, and chiefly of the central tongue, in all those respects in which in consequence of its own special character it should remain individually defective. The new Scientific and Central Language might thus plant itself in the midst of the Languages; gradually assimilate them to itself; drawing at the same time an augmentation of its own materials from them, until they would become mere idioms of it, and finally, perhaps, in a more remote future, disappear altogether as distinct forms of speech, and be blended into harmony in the bosom of the central tongue.
