An international conference that takes Philosophy Educating Humanity as its theme does well to revisit the liberal arts tradition. Although the liberal arts are most often assimilated to studies brought together as the Humanities, the old usage included the arts which employed artificial languages in mathematics, music, and astronomy, as well as the literature and letters of the various natural languages. The current conflation of liberal education with the humanities does violence to the historical tradition in education, reducing it to fluff in the eyes of tough-minded scientists who know that only numbers deliver objectivity. The liberal arts of the traditional undergraduate curriculum provided the skills to liberate the student's linguistic powers so that he or she could read, speak, and understand natural language in all its functions. To educate human persons to master language is to encourage students to take possession of their natural powers so that they can express themselves, understand what others say, and reason together. The arts of natural language lead to mastery of the mathematical arts which use a language that is no one's mother tongue. Together, the seven arts rid students of the worst enemies of humankind: ignorance and prejudice.
