Syllogisms and Enthymemes

Syllogism: Syllogism is a rhetorical device that starts an argument with a reference to something general and from this it draws conclusion about something more specific.

Syllogisms  a form of reasoning in which a conclusion is drawn (whether validly or not) from two given or assumed premises, each of which shares a term with the conclusion, and shares a common or middle term not present in the conclusion

Syllogism: Let us try to understand the concept with the help of an example. We start with a general argument “All men are mortal,” we know that “John is a man” so “John is mortal.” It is a deductive approach to reason and is based on deducing specific conclusions from general facts.

Syllogism: deductive reasoning as distinct from induction. (e.g., all dogs are animals; all animals have four legs; therefore all dogs have four legs ). deductive reasoning as distinct from induction.

Syllogism: We notice in the above example that Syllogism is a three-part set of statements; a major statement or premise, a minor statement or premise and a conclusion that is deduced. Therefore, “All men are mortal” is a major statement or premise which stands as a general fact. “John is a man” is minor statement or premise that is specific and “John is mortal” is the logical conclusion deduced from the two prior statements.

Syllogism / Enthymeme Syllogism takes the form of Enthymeme when it is compressed. Enthymeme combines the minor premise and the conclusion and omitting the major statement.

Syllogism / Enthymeme For instance, a syllogism “All dogs are canine. Tommy is a dog. Therefore, Tommy is a canine.” can be compressed in an enthymeme as “Tommy is a canine because it is a dog.” The major premise remains implied or hidden.

Syllogism Fallacy Syllogism may also be used to form incorrect conclusions that are odd. For instance, “All crows are black and the bird in my cage is black. So, the bird in my cage is a crow.” This is a false argument as it implies a conclusion “all blackbirds are crows” is incorrect. It is known as Syllogism Fallacy. Another example of Syllogism fallacy is “Some televisions are black and white and all penguins are black and white. Therefore, some televisions are penguins”. You can easily see that the conclusion is practically impossible and in fact has a comical outcome.

Syllogism Purpose Function of Syllogism In logic, syllogism aims at identify the general truths in a particular situation. It is a tool in the hands of a speaker or a writer to persuade the audience or the readers as their belief in a general truth may tempt them to believe in a specific conclusion drawn from those truths. In literature, syllogism can contribute to add wit to the statements. Moreover, Syllogism fallacy may give us an opportunity to enjoy the nonsensical conclusion.
