Sect. 4.1 reading - The Components of Categorical Propositions

categorical proposition

a proposition that relates two classes (or categories).

subject term

in a standard-form categorical proposition, the term that comes immediately after the quantifier.

predicate term

in a standard-form categorical proposition, the term that comes immediately after the copula.

1). assert that the whole subject class is included in the predicate class,

2). assert that part of the subject class is included in the predicate class,

3) assert that the whole subject class is excluded from the predicate class,

4). assert that part of the subject class is excluded from the predicate class.

the four types of categorical propositions:

standard-form categorical proposition

a proposition that has one of the following forms: “All S are P;” “No S are P”; “Some S are P”; “Some S are not P.”

quantifiers

in standard-form categorical propositions, the words “all,” “no,” and “some.”

copula

in standard-form categorical propositions, the words “are” and “are not.”
