 Bacon’s concerns with language in his later works transgress the disciplinary boundaries of the medieval university. First, he demands that the universities study the Wisdom languages, i.e., Hebrew, Greek, Latin in one list, or Hebrew, Greek, Arabic, and Chaldean in another. He wrote Greek and Hebrew grammars (GGHG). Bacon takes Latin as a model for a natural language, the “mother language” of the West. For Bacon, this language is dependent on Greek and Hebrew. He distinguishes the “vulgar language” or “language of the laity” from the “language of learning” of the clergy. For him, vulgar language cannot be used in learning; it does not have an adequate technical vocabulary.
