444 The Loom of Language voyages of discovery Navigation and missionary fervour fostered new knowledge of near and middle Eastern languages, including Coptic, Ethiopic, and Persian It made samples of Amerindian, of Dravidian, of Malay, and of North Indie vernaculars available to European scholars In becoming Bible-conscious, Europe became Babel-consaous One linguistic discovery of the seventeenth century is of special importance, because it suggested a possible remedy for the confiision of tongues. The labours of Jesuit missionaries diffused new knowledge about Chinese script. To seventeenth-century Europe Chinese, a script which substituted words for sounds, was a wholly novel way of writing. Still more novel was one consequence of doing so To the reader of the Loom it is now a commonplace that two people from different parts of China can read the same texts without being able to converse with one another To seventeenth-century Europe it was a nine days' wonder, and the knowledge of it synchronized with a spectacular innovation. Symbolic algebra was taking new shapes The invention of logarithms and the calculus of Leibniz, himself in the forefront of the linguistic movement, gave mankind an international vocabulary of computation and motion Without doubt, the novelty of mathematical symbolism and the novelty of Chinese logographic writing influenced the first proposals for a system of international communication through script Leibniz corresponded with Jesuit missionaries to find out as much as possible about Chinese; and Descartes, the French philosopher-mathematician, outlined a scheme for a constructed language in 1629 Thanks to our Hindu numerals, anyone—and by anyone Descartes meant anyone except the common people of his time—can master the art of naming all possible numbers which can exist in any language in less than a days' work. If so, the ingenuity of philosophers should be up to the job of finding equally universal symbols for things and notions set out in a systematic way. These would be the bricks of a language more logical, more economical, more precise, and more easy to learn than any lan- guage which has grown out of the makeshifts of daily intercourse At least, that is what Descartes believed He did not put his conviction to the test by trying to construct a universal catalogue of things and notions. Forty years later the dream materialized. In 1668 Bishop Wilkins published the Essay towards a Real Character and a Philosophical Language Wilkins was not first in the field George Dalgarno, of Abefdeen, also author of a language for the deaf and dumb, and inventor of a new
