The standard form of an argument is a way of presenting the argument which makes clear which statements are premises, how many premises there are, and which statements is the conclusion. In standard form, the conclusion of the argument is listed last.

A categorical syllogism infers a conclusion from two premises. It is defined by the following four attributes. Each of the three propositions is an A, E, I, or O proposition. The subject of the conclusion (called the minor term) also occurs in one of the premises…

A. Standard-Form Categorical Syllogisms. A categorical syllogism is an argument containing three categorical propositions: two premises and one conclusion. The most methodical way to study categorical syllogisms is to learn how to put them in standard-form, which looks like: Major premise.

To be in standard form a categorical syllogism meets the following strict qualifications:

1. · It is an argument with two premises and one conclusion.
2. ·
3. · Major term (P) = Predicate of conclusion.
4. · Minor term (S) = Subject of conclusion.
5. · Middle term (M) = Term that occurs in both premises.

Thus, categorical propositions are of four basic forms: “Every S is P,” “No S is P,” “Some S is P,” and “Some S is not P.” These forms are designated by the letters A, E, I, and O, respectively, so that “Every man is mortal,” for example, is an A-proposition.

In this chapter we will be looking at a special kind of statement called categorical. They are so called because sentences that express them can be interpreted as asserting a relation between two categories or classes of things. Some examples of sentences expressing categorical statements are: All mice are rodents.

There are four types of categorical proposition, each of which is given a vowel letter A, E, I and O. A way of remembering these is: Affirmative universal, nEgative universal, affIrmative particular and nOgative particular.

Translation Rules of Thumb:

1. Rule 1: The subject and predicate terms must be the names of classes.
2. Rule 2: Categorical propositions should have a form of the verb “to be” as the copula in the present tense.[1]
3. Rule 3: The quality and quantity indicators are set up from the meaning of the sentences.

In order to make obvious the similarities of structure shared by different syllogisms, we will always present each of them in the same fashion. A categorical syllogism in standard form always begins with the premises, major first and then minor, and then finishes with the conclusion.

33. To reduce a proposition to its logical form, the following steps must be taken: 1. First, state the subject with an appropriate word to express its quantity, usually “all” or “some” 2. Then express its copula in the form of “am”, “is”, or “are” (“not” should be added if the proposition is negative) 3.

All logical form arguments are either inductive or deductive. The most reliable forms of logic are modus ponens, modus tollens, and chain arguments because if the premises of the argument are true, then the conclusion necessarily follows.

Logic is the science that evaluates arguments. An argument is a group of statements including one or more premises and one and only one conclusion. A premise is a statement in an argument that provides reason or support for the conclusion. There can be one or many premises in a single argument.

Sometimes the best evidence for your argument is a hard fact or visual representation of a fact. This type of evidence can be a solid backbone for your argument, but you still need to create context for your reader and draw the connections you want him or her to make.
