Abstract

This volume provides the first critical edition of Abbo of Fleurys "De Syllogismis Hypotheticis," together with a German translation, an introduction and an extensive commentary. Abbo of Fleury (940/45-1004) was the first medieval author to write on hypothetical syllogisms. He relies mostly on Boethius, but he must have had at his disposal a further source which has since been lost.
