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?

宾根圣希尔德加德的生态素养

从字面上看，识字不是教育问题，而是文字问题。更重要的是，这是一个字母在英语中的两种含义的问题：作为字母表的符号和一段对应关系。我的假设是生态文学可以从字母的字面化甚至超字面化中学到很多东西，并且他们可以通过转向 12 世纪本笃会修道院院长、博学者和神秘的圣约翰的语料库来做到这一点。宾根的希尔德加德。毕竟，希尔德加德 (Hildegard) 对植物世界非常了解，这是她神学和科学努力的核心，她通过信函与她那个时代的主要人物通信，还发明了一种语言，称为lingua ignota（未知语言）充满ignotas litteras（未知字母）。谁能比她更能说出生态素养的含义？
