 The next chapters proceed to consider “conjunctive” syllogisms. Such syllogisms include, for example, a conditional proposition in a premise or the conclusion or a disjunction in the major premise. No new formal rules are introduced to deal with these. Instead, the Logic again runs through many examples which are treated by inspection (as we now say) making use of “the natural light of reason” (III.9, 158, see also p. 23). This is understandable given the scope of the general principle established in the preceding chapters.
