Syllogisms

It is a figure of deductive thinking which contains two premises (the major and minor) or Judgments inferred conclusion.

Classification of trials or Premises

A = Affirmative Universal .- Includes all items. Every human dies.

Universal Negative E = .- rejects all elements. No human is vegetable.

I = Individual Affirmative .- Includes some elements. Some humans have twins.

O = .- Not Particular Negative include some elements. Some animals are carnivores.

Two basic characteristics of the syllogisms are:

Truth = that what is said or preached is true.

Validity = probable syllogisms That match the three figures or models exactly unchanged.
Some rules of the syllogism:

Every syllogism must have three terms. (M, S, P)

Two negative premises nothing is concluded.

Two particular premises nothing is concluded.

Two positive premises, positive conclusion.

Do not use a term with two meanings (amphibology).

Every premise must be true. (Truth).

Each syllogism must match the figure to which it belongs.

Universal conclusion from two premises Universal.

Figures of the syllogism:

We can affirm or deny the major term (A) the average (B), and affirm the average (B) the lesser term C, using different types of propositions.

We can affirm or deny the term average major and minor term, which gives us another arrangement of the terms. The middle term is predicate of both premises.

The major term may be affirmed or denied of the middle term and the term child can be said of the average in the minor premise. The average appears as the subject of both premises.
