|1.||an incomplete syllogism, in which one or more premises are unexpressed as their truth is considered to be self-evident|
|2.||any argument some of whose premises are omitted as obvious|
|[C16: via Latin from Greek enthumēma, from enthumeisthai to infer (literally: to have in the mind), from |
in syllogistic, or traditional, logic, name of a syllogistic argument that is incompletely stated. In the argument "All insects have six legs; therefore, all wasps have six legs," the minor premise, "All wasps are insects," is suppressed. Any one of the propositions may be omitted-even the conclusion; but in general it is the one that comes most naturally to the mind. Often in rhetorical language the deliberate omission of one of the propositions has a dramatic effect. This use of the word differs from Aristotle's original application of it (in his Prior Analytics, ii, 27) to a rhetorical syllogism (employed for persuasion instead of instruction) based on "probabilities or signs"; i.e., on propositions that are generally valid or on particular facts that may be held to justify a general principle or another particular fact.
