 The second major division of hypothetical syllogisms consisting of a conditional and a categorical premise obtains when the sharing occurs in the antecedent. The analysis of these syllogisms is the subject of Qiyās VI.5, which is the only place in the corpus where they are treated explicitly. Elsewhere (e.g., Nağāt 82), hypothetical syllogisms of this kind are said to be less used in the sciences. In spite of the structural analogy to the cases discussed above (the conclusion is still a conditional proposition, even though here the categorical “fragment” occupies the place of the antecedent), the way the quantification of the conditional and the quantification of the antecedent interact generate results that do not generally mirror categorical syllogisms. The classification is parallel to the previous case and consists of two main groups: the first with a conditional major and a categorical minor, the second with a categorical major and a conditional minor. Each group is divided into three figures, as above, and the moods of each figure are analyzed with respect the four combinations of quality and quantity of the conditional premise.
