An enthymeme is a particular means of expressing a syllogistic argument which has one proposition suppressed— i.e. , one proposition (either a premiss or a conclusion) is not stated. 2  In ordinary language, nearly all syllogistic arguments are expressed as enthymemes.

- The rules of this test are simple: it's your job to determine whether an argument is valid or not. All the arguments are syllogisms. Here is a standard example: All humans are mortal. All Greeks are humans. Therefore, all Greeks are mortal. An argument is valid if and only if the conclusion necessarily follows from the premises. Thus, the argument above is valid, because if all humans are mortal, and if all Greeks are human, it follows as a matter of logical necessity that all Greeks are mortal. It is important to stress that this kind of logical entailment has nothing to do with the truth of the premises or conclusion.
