This article highlights the long accomplishments of Claude Sumner, S.J. in the field of African philosophy. During his lifetime he published over 33 books and 184 articles. He lived and worked in Ethiopia for 44 years. He translated into English and analysed several key historical works in Ethiopian philosophy, written originally in Ge’ez. He argued that modern rationalist philosophy began in Africa with Zera Yacob at the same time that it began in France with Descartes. He then set to work (...) recording and analyzing oral philosophical sources found in proverbs and songs. He theorized on the definitions of philosophy and the methods to explore philosophy found in different sources. (shrink)
