 Amo matriculated at the university in nearby Wittenberg the following year, and was promptly awarded a Magister in philosophy. While in Wittenberg, Amo wrote a dissertation, entitled De humanae mentis apatheia (On the Impassivity of the Human Mind) in 1734, which qualified him to teach, and later in the same year he supervised a dissertation which he is also thought to have had a hand (at least) in writing (Menn &amp; Smith 2020: 68–71). Amo would return to teach philosophy at Halle, and in 1738 published a wide-ranging manual for his philosophical lectures, Tractatus de arte sobrie et accurate philosophandi (Treatise on the Art of Philosophizing Soberly and Accurately). Not long after, however, Amo applied for a position at the University of Jena, claiming indigence, and was granted permission to lecture there in 1740. For reasons that we can only speculate about, Amo would request passage on a ship to return to Africa in 1746 (Menn &amp; Smith 2020: 38), and it was in Axim that a Swiss doctor would report encountering Amo in the early 1750s. Amo is thought to have died not long after.
