He went on to the University of Halle, whose Law School he entered in 1727. He finished his preliminary studies within two years, titling his thesis "Dissertatio Inauguralis de Jure Maurorum in Europa" (1729). This manuscript on "The Rights of Moors in Europe" is lost, but a summary was published in his university's "Annals" (1730). For his further studies Amo moved to the University of Wittenberg, studying logic, metaphysics, physiology, astronomy, history, law, theology, politics, and medicine, and mastered six languages (English, French, Dutch, Latin, Greek, and German). His medical education in particular was to play a central role in much of his later philosophical thought.
