Abstract

Literacy is, literally, a question not of education but of the letter. More than that, it is the question of the letter in the two senses the word has in English: as a symbol of the alphabet and a piece of correspondence. It is my hypothesis that ecological literacies may learn a great deal from the literalization, or even the hyper-literalization, of the letter and that they may do so by turning to the corpus of twelfth-century Benedictine abbess, polymath, and mystic St. Hildegard of Bingen. After all, Hildegard, who was exquisitely attuned to the vegetal world, which was at the core of her theological and scientific endeavors, corresponded through letters with the leading personalities of her times and also invented a language, called _lingua ignota_ (the unknown language) replete with _ignotas litteras_ (the unknown letters). Who better than her can spell out the senses of ecological literacy?
