Enthymeme(n.) An argument consisting of only two propositions, an antecedent and consequent deduced from it; a syllogism with one premise omitted; as, We are dependent; therefore we should be humble. Here the major proposition is suppressed. The complete syllogism would be, Dependent creatures should be humble; we are dependent creatures; therefore we should be humble.
