Anton Wilhelm Amo or Anthony William Amo (c. 1703 – c. 1759) was an African from what is now Ghana, who became a respected philosopher and teacher at the universities of Halle and Jena in Germany after studying there. Brought to Germany by the Dutch West India Company in 1707 as a child, and given as a gift to the Dukes of August Wilhelm and Ludwig Rudolf von Wolfenbuttel, he was treated as a member of the family of Anthony Ulrich, Duke of Brunswick-Wolfenbuttel, he was the first African known to have attended a European university.
Amo was a Nzema (an Akan people). He was born in Awukena in the Axim region of present-day Ghana, but at the age of about four he was taken to Amsterdam by the Dutch West India Company. Some accounts say that he was taken as a slave, others that he was sent to Amsterdam by a preacher working in Ghana. Whatever the truth of the matter, he was given as a "present" to Anthony Ulrich, Duke of Brunswick-Wolfenbuttel, to whose palace in Wolfenbuttel he was taken.
Amo was baptised (and later confirmed) in the palace's chapel. He was treated as a member of the Duke's family, and was educated at the Wolfenbuttel Ritter-Akademie (1717–1721) and at the University of Helmstedt (1721–1727).
He went on to the University of Halle, whose law School he entered in 1727. He finished his preliminary studies within two years, his dissertation being: “The Rights of Moors in Europe”. 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.
He gained his doctorate in philosophy at Wittenberg in 1734; his thesis (published as On the Absence of Sensation in the Human mind and its Presence in our Organic and Living body) argued against Cartesian dualism in favour of a broadly materialist account of the person. He accepted that it is correct to talk of a mind or soul, but argued that it is the body rather than the mind which perceives and feels.
Whatever feels, lives; whatever lives, depends on nourishment; whatever lives and depends on nourishment grows; whatever is of this nature is in the end resolved into its basic principles; whatever comes to be resolved into its basic principles is a complex; every complex has its constituent parts; whatever this is true of is a divisible body. If therefore the human mind feels, it follows that it is a divisible body.
Amo returned to the University of Halle to lecture in philosophy under his preferred name of Antonius Guilelmus Amo Afer. In 1736 he was made a professor. From his lectures, he produced his second major work in 1738, Treatise on the Art of Philosophising Soberly and Accurately, in which he developed an empiricist epistemology very close to but distinct from that of philosophers such as John Locke and David Hume. In it he also examined and criticised faults such as intellectual dishonesty, dogmatism, and prejudice.
In 1740 Amo took up a post in philosophy at the University of Jena, but while there he experienced a number of changes for the worse. The Duke of Brunswick-Wolfenbuttel had died in 1735, leaving him without his long-standing patron and protector. That coincided with social changes in Germany, which was becoming intellectually and morally narrower and less liberal. Those who argued against the secularisation of education (and against the rights of Africans in Europe) were regaining their ascendancy over those (such as Christian Wolff) who campaigned for greater academic and social freedom.
Amo was subjected to an unpleasant campaign by some of his enemies, including a public lampoon staged at a theatre in Halle. He finally decided to return to the land of his birth. He set sail on a Dutch West India Company ship to Ghana via Guinea, arriving in about 1747; his father and a sister were still living there. His life from then on becomes more obscure. According to at least one report, he was taken to a Dutch fortress, Fort San Sebastian, in the 1750s, possibly to prevent him sowing dissent among his people. The exact date, place, and manner of his death are unknown, though he probably died in about 1759 at Fort Chama in Ghana.
Later, during the time of German idealism and romanticism, Amo's philosophical work was ignored by other Jena-based German intellectuals such as Schiller, Fichte, Schelling, Hegel, Brentano, or the Schlegel brothers.He is cited in "De la litterature des negres" (1808) of l'Abbe Gregoire.
