 Abelard’s hypothetical syllogistic does not repeat Boethius’ mistake of mixing a term logic like the theory of the syllogism with a sentential logic. Rather, Abelard’s work should be seen as a very sophisticated development of a sentential logic. I will therefore not treat it in this overview, since it belongs to the history of sentential logic rather than syllogistic. It seems that the medievals also rather quickly stopped associating the word ‘syllogism’ with this theory.
