Niko Strobach: Neuere Interpretationen der aristotelischen Syllogistik (PDF; 112 kB), Seite 13, insbesondere das dort gebrachte Prior-Zitat „The Prior Analytics ... is not a book of syllogisms, but a book about syllogisms, and the statement ‚If B is predicable of every M, and M of every A, then B is predicable of every A‘ is a perfectly natural way of talking about syllogisms of the form ‚Every B is M, and every M is A, therefore etc.‘, and saying that all such syllogisms are valid.“
