 In hypothetical syllogisms with two conditional premises, the shared part is a proposition which plays the same role as the middle term in categorical syllogisms. Depending on whether it is (i) the consequent of the major premise and the antecedent of the minor, (ii) the consequent of both or (iii) the antecedent of both, arguments of this kind will fall into one of the three familiar figures. The moods in each figure are determined here in function of the quality and quantity of the conditional premises and conclusion, unlike in the case of combinations involving a categorical and a conditional, where figures and moods, as we shall see below, are determined by the categorical premise and another categorical proposition, which is either the consequent or the antecedent of the other (conditional) premise.
