Comenius was a severe critic of the defects of natural languages. In his Pansophiae Christianae liber III (1639-40), he advocated a reform that would eliminate the rhetorical and figurative use of words, which he regarded as a source of ambiguity. The meaning of words should be fixed, he demanded, with one name of each thing, thus restoring words to their original meanings. In 1668, in the Via lucis, Comenius offered prescriptions for the creation of an artificial universal language. By now, pansophy was more than an educational method; it was a utopian vision in which a world council was supposed to create the perfect state along with its perfect philosophical language, the Panglottia. It is interesting to concider that Comenius had in fact written this work before 1641, when, after wandering through the whole of Europe in the course of the Thirty Years War, he had taken refuge in London. Via lucis certainly circulated, in manuscript form, in the English milieu at that time (see, for example Cram 1989). Although Comenius was never to construct his new language in extenso, he had broached the idea of a universal tongue which had to overcome the political and structural limitations of Latin. […] Comenius became the forerunner of that search for an a priori philosophical language that would later be implemented by English utopian thinkers whose inspiration was more scientific than theological or mystical.
